Community-based services that tap into local environments not only reduce the duration of untreated psychosis (DUP) but also provide improved long-term outcomes for patients with first-episode psychosis (FEP), results of two new studies show.

In the first study, investigators led by Vinod Srihari, MD, director of specialized treatment early in psychosis at Yale University, New Haven, Conn., developed a program to reduce DUP to complement their first-episode service (FES).

Through a combination of mass media and social media campaigns, outreach events with local professionals, and rapid triage, the team was able to nearly halve the time from diagnosis to initiation of antipsychotic treatment.

In the second study, a team led by Delbert G. Robinson, MD, of Hofstra University, Hempstead, N.Y., conducted a 5-year follow-up of RAISE-ETP, the first U.S. randomized trial to compare a 2-year comprehensive early intervention service (EIS) with usual care.

These trial results showed that, among more than 400 FEP patients, the EIS significantly improved both symptoms and quality of life and reduced inpatient days in comparison with standard care.

The research was scheduled to be presented at the Congress of the Schizophrenia International Research Society (SIRS) 2020, but the meeting was canceled because of the coronavirus pandemic.
 

Norwegian model

Dr. Srihari and colleagues note that a specialized treatment early in psychosis (STEP), which delivers a specialty team–based FES, was established at their institution in 2006.

However, in a bid to reduce DUP, in 2015 they launched MindMap, a 4-year early-detection campaign based on the Scandinavian TIPS Early Detection in Psychosis Study.

Dr. Srihari said in an interview that they visited the team that developed the TIPS program in Norway “to try to understand what elements of their approach had resulted in a successful reduction of DUP.”

He pointed out that the health care system in Norway has “more reliable pathways to care, with an ability to route people in more predictable ways from primary care to secondary care, and so on.”

In the United States, “there’s no expectation that people will go through a primary care provider,” he said. He noted that patients “make their way to specialty care in many different ways.”

Dr. Srihari said, “The other change we realized we’d have to make was that, since TIPS had been completed many years back, the media environment had changed substantially.

“At the time that TIPS was done, there was no such thing as social media, whereas when we began to think about designing our campaign, we thought social media would be a very efficient and also cost-effective way to target young people.”

MindMap, which covered a 10-town catchment area that has a population of 400,000, targeted both demand- and supply-side aspects of DUP. The former focused on delays in identifying illness and help-seeking, and the latter concentrated on referral and treatment access delays.

The researchers used a combination of mass media and social media messaging, professional detailing, and the rapid triage of referrals.

The media campaign included Facebook, Twitter, and other social media platforms that allowed the team to “target individuals in a somewhat more fine-grained way than mass media allows,” Dr. Srihari said. They focused on individuals in a particular age range and geographic location.

The professional detailing encompassed mental health agencies, emergency departments, and inpatient units, as well as colleges, college counseling centers, high schools, and police departments. The team hosted meetings, “often at local restaurants, where we provided a meal and provided some general education about what our mission was,” said Dr. Srihari. The researchers followed up these meetings with more in-person visits.

“The third arm was finding ways to basically eliminate any kind of a waiting time at our front door, such as ensuring that transportation issues were circumvented, in addition to cutting through any ambivalence they might have about finally making the leap to come to the center.”
 

More rapid treatment

Over the course of the baseline year and the 4 years of the MindMap program, almost 1,500 individuals were assessed. Of these, approximately 200 were eligible, and almost all were enrolled.

The researchers measured DUP at two time points from the onset of psychosis – the initiation of antipsychotic treatment (DUP1) and the initiation of FES care. Across the study period, they found that DUP1 fell significantly between the pre- and postprogram assessments, from 329 days to 185 days (P = .03). By contrast, there was no change over the same period for the Prevention and Recovery in Early Psychosis FES program in Boston, which served as a comparator.

There was also a cumulative effect on DUP, with each year of the 4-year program associated with a 46-day reduction in DUP1. However, the significant reduction was restricted to the third quintile of DUP1 and was not found in the other quintiles of DUP1 or for DUP2, despite all measures showing a consistent trend for reduction over time.

Dr. Srihari acknowledges that the team was “disappointed” that DUP2 did not fall significantly in their study. He suggested, “It might take longer for agencies to change their workloads and refer patients to STEP, which is what ended up resulting in the DUP2 not dropping as quickly.”

To see whether there was indeed a time lag in changes to practice, the team conducted an analysis in which they cut out the first year from the results and analyzed only the last 3 years. Then “we do see a decline in DUP2,” he said.

The study’s full results are currently being prepared for publication, and the investigators are considering relaunching the initiative.

“The question we are having now is how to resource the campaign without the research funds and which parts of it we think we can launch sustainably so we can continue the reduction of DUP,” Dr. Srihari said.

Plans may include developing partnerships with local businesses to help fund the media costs and working with the state government to build a learning health care network, which would make it easier for mental health agencies to consult with the team on problematic cases.

“We’re trying to reduce DUP referrals on the supply side by providing this kind of learning health collaborative ... that we also think might be fiscally a more sustainable way to do this vs. what we did in MindMap,” which would be “very expensive” to implement on a statewide basis, Dr. Srihari added.
 

Long-term benefit

In the second study, Dr. Robinson and colleagues highlight that EISs have been implemented worldwide for FEP patients and have been associated with improved outcomes.

However, these services typically provide care for a limited period, and cross-sectional follow-up studies have identified few advantages in comparison with standard care.

To provide a more robust longitudinal assessment of the ongoing effects of an EIS, the team conducted a 5-year follow-up of the first U.S.-based, multicenter, randomized clinical trial comparing an EIS, NAVIGATE, with usual clinical care in FEP.

RAISE-ETP was conducted at 34 sites across the United States. Seventeen sites provided NAVIGATE to 223 individuals with FEP, and the remaining 17 sites provided usual care to 181 patients.

NAVIGATE, which continued for 2 years, consisted of treatments and services delivered by a coordinated team of providers. Those services included the following:

• Education on schizophrenia and its treatment for patients and their families.
• Symptom and relapse prevention medication, using a computerized decision support system.
• Strategies for illness management building personal resilience.
• A supported employment/education model.

Patients were assessed every 6 months for up to 60 months via a video link using the Heinrichs-Carpenter Quality of Life Scale (QLS) and the Positive and Negative Syndrome Scale (PANSS).

The average age of the participants was 23 years; 78% of those who received NAVIGATE and 66% of those who received usual care were male. The opportunity for each participant to engage in NAVIGATE treatment lasted an average of 33.8 months. The longest was 44.4 months.

Over 5 years, NAVIGATE was associated with a significant improvement over usual care in QLS scores by an average of 13.14 units (P < .001). PANSS scores improved by an average of 7.73 units (P < .002). QLS scores were not affected either by the length of opportunity to participate in NAVIGATE or by DUP, the team reports. Patients who received NAVIGATE also had an average of 2.5 fewer inpatient days, compared with those on usual care (P = .02).

The investigators note that the study “provides compelling evidence of a substantial long-term benefit for FEP treatment with the NAVIGATE EIS, compared with standard care.”
 

A ‘great message’

Commenting on the findings in an interview, Ragy R. Girgis, MD, associate professor of clinical psychiatry at Columbia University, New York, and the New York State Psychiatric Institute, said the research “adds to the growing literature that treating people, especially people with psychosis, early on in their illness leads to better outcomes.”

Dr. Girgis, who was not involved in either study, said that the research is “a great message.” He noted that it is “really important for people to know and it’s really important that we’re still doing research in those areas.”

However, he noted that psychosocial interventions such as these “sometimes take a lot of work.” Dr. Girgis said that it is “so easy to just give people a medication” but that approach has its own disadvantages, including adverse effects and sometimes a lack of efficacy.

“Psychosocial interventions, on the other hand, are very well tolerated by people. They are very effective, but they may require a lot more manpower, and in some ways they can also be more expensive.

“So this is a dialectic that we oftentimes have to deal with when we figure out the right balance between psychosocial vs. medication types of treatments,” he said.

STEP has received research funding from the National Institutes of Health and the Patrick and Catherine Weldon Donaghue Medical Research Foundation. RAISE-ETP was funded by the National Institute of Mental Health as part of the Recovery After an Initial Schizophrenia Episode (RAISE) Project.

ACE levels are lower in individuals with first episode psychosis (FEP) and even lower in those with resistant disease, suggesting the enzyme may be a biomarker of disease severity.

In a longitudinal cohort study, investigators found patients with FEP had significantly reduced ACE levels compared with their healthy peers.

With blood concentrations of the enzyme significantly reduced in those who were treatment-resistant, “ACE alterations appear to be already present at the disease onset” and results suggest “a possible relationship with disease severity,” noted the researchers, led by investigator Luisa Longo, MD, a resident in psychiatry, University of Bari Aldo Moro in Italy.

Moreover, the finding that lower ACE levels were associated with greater cognitive impairment on neuropsychological tests indicates the enzyme plays a role in “the alteration of neurocognitive abilities” in patients with FEP.

Taken together, the results “highlight ACE as a promising peripheral biomarker to identify patients at risk of treatment resistance to antipsychotics,” the investigators reported.

The findings were presented at the annual congress of the Schizophrenia International Research Society.
 

Mechanisms “poorly understood”

Previous studies suggest ACE may play a role in neurologic and psychiatric conditions, including schizophrenia, through alterations in function or blood concentrations.

However, the molecular mechanisms underlying disease onset and response to antipsychotics in patients with FEP “remain poorly understood,” the researchers noted. In addition, “despite adequate antipsychotic treatment, 20% of patients have persistent symptoms.”

To determine whether ACE levels are already altered in FEP patients, the investigators examined data on 138 patients with FEP and 115 healthy controls.

After measuring blood concentrations in 122 of the patients and 78 controls, they found that ACE levels were significantly lower in FEP patients (P = 4.1x10-13) after controlling for age, sex, ethnicity, duration of illness, smoking status, and chlorpromazine equivalents.

Cerebrospinal fluid (CSF) levels, which were measured in 19 patients and 18 controls, were also significantly lower in individuals with FEP (P = .01), with a strong correlation observed between blood and CSF levels (P = .0005).

Next, the team used Treatment Response and Resistance in Psychosis criteria to compare ACE levels in 32 treatment-resistant patients and 106 non–treatment-resistant patients. Results showed that ACE blood levels were significantly lower in the treatment-resistant patients (P = .03).

Finally, the association between ACE blood levels and range of clinical and neurocognitive variables were examined across all FEP patients.

The Scale for the Assessment of Negative and Positive Symptoms was administered, along with a battery of tests looking at processing speed, working memory, verbal learning and memory, visual learning and memory, ideational fluency, and executive function. All were combined into a composite score.

While there was no association between ACE blood levels and symptom severity in the patients, there was a significant association between levels and verbal memory (P = .007) and composite cognitive score (P = .04).
 

Notable finding

In an interview, Thomas W. Sedlak, MD, PhD, assistant professor of psychiatry and behavioral health, Johns Hopkins University, Baltimore, said the finding that ACE levels were associated with lower cognition scores is “notable in that we don’t really have any treatments for cognition.

“Antipsychotic drugs treat more of the famous symptoms of hallucinations and delusions and disordered speech, but they don›t really help cognition a whole lot — and too much medicine might even make that worse,” said Dr. Sedlak, who was not involved with the research.

“So it’s interesting to have another biomarker that might relate a symptom of schizophrenia that we don’t really have a good grip on addressing,” he said.

However, he noted that this study is “preliminary,” has not looked at longitudinal changes in ACE in the same patients, and is one of “many” correlation studies.

“I like to say you can pretty much Google any chemical in the body and somebody has a claim about it and schizophrenia,” Dr. Sedlak said.

Nevertheless, the current analysis is “convergent” with past studies on ACE, including those that have found associations between polymorphisms in the enzyme and schizophrenia, he noted.

Moreover, research has shown that ACE facilitates glutamate transmission, specifically via N-methyl-D-aspartate (NMDA) receptors in the prefrontal cortex, “which is probably the brain region most tied to schizophrenia abnormalities,” Dr. Sedlak said.
 

No tie to inflammation

The findings do contrast, however, with the increasing body of evidence linking schizophrenia to inflammation.

Dr. Sedlak said that is not surprising, as the more that is learned about schizophrenia, “the less it is likely to be a single homogeneous entity but something more akin to intellectual disability.

“We’re finding that there are different subtypes of schizophrenia, some of which might have more of an inflammatory tie and others which don’t.”

He added that it might be possible over the longer term to cluster patients by ACE levels and other biomarkers and then follow them long term to “see if we can predict outcomes better than purely clinical terms.”

In this way, Dr. Sedlak said he believes that psychiatry may become more like rheumatology, “which I’d say is the area of medicine, at least in terms of making diagnoses, most similar.”

The etiology of conditions such as lupus and rheumatoid arthritis is “not absolutely known” and there is “probably no single cause,” with the diagnosis relying on clinical findings alongside biomarker tests.

“I think psychiatry is, long term, hoping to discover some biomarkers ... that would be used together with the clinical findings to help come to more clinical agreement on how to define cases – and would be predictive long term in terms of the course of illness,” Dr. Sedlak concluded.

The study had no specific funding. The study investigators and Dr. Sedlak have disclosed no relevant financial relationships.

ACE levels are lower in individuals with first episode psychosis (FEP) and even lower in those with resistant disease, suggesting the enzyme may be a biomarker of disease severity.

In a longitudinal cohort study, investigators found patients with FEP had significantly reduced ACE levels compared with their healthy peers.

With blood concentrations of the enzyme significantly reduced in those who were treatment-resistant, “ACE alterations appear to be already present at the disease onset” and results suggest “a possible relationship with disease severity,” noted the researchers, led by investigator Luisa Longo, MD, a resident in psychiatry, University of Bari Aldo Moro in Italy.

Moreover, the finding that lower ACE levels were associated with greater cognitive impairment on neuropsychological tests indicates the enzyme plays a role in “the alteration of neurocognitive abilities” in patients with FEP.

Taken together, the results “highlight ACE as a promising peripheral biomarker to identify patients at risk of treatment resistance to antipsychotics,” the investigators reported.

The findings were presented at the annual congress of the Schizophrenia International Research Society.
 

Mechanisms “poorly understood”

Previous studies suggest ACE may play a role in neurologic and psychiatric conditions, including schizophrenia, through alterations in function or blood concentrations.

However, the molecular mechanisms underlying disease onset and response to antipsychotics in patients with FEP “remain poorly understood,” the researchers noted. In addition, “despite adequate antipsychotic treatment, 20% of patients have persistent symptoms.”

To determine whether ACE levels are already altered in FEP patients, the investigators examined data on 138 patients with FEP and 115 healthy controls.

After measuring blood concentrations in 122 of the patients and 78 controls, they found that ACE levels were significantly lower in FEP patients (P = 4.1x10-13) after controlling for age, sex, ethnicity, duration of illness, smoking status, and chlorpromazine equivalents.

Cerebrospinal fluid (CSF) levels, which were measured in 19 patients and 18 controls, were also significantly lower in individuals with FEP (P = .01), with a strong correlation observed between blood and CSF levels (P = .0005).

Next, the team used Treatment Response and Resistance in Psychosis criteria to compare ACE levels in 32 treatment-resistant patients and 106 non–treatment-resistant patients. Results showed that ACE blood levels were significantly lower in the treatment-resistant patients (P = .03).

Finally, the association between ACE blood levels and range of clinical and neurocognitive variables were examined across all FEP patients.

The Scale for the Assessment of Negative and Positive Symptoms was administered, along with a battery of tests looking at processing speed, working memory, verbal learning and memory, visual learning and memory, ideational fluency, and executive function. All were combined into a composite score.

While there was no association between ACE blood levels and symptom severity in the patients, there was a significant association between levels and verbal memory (P = .007) and composite cognitive score (P = .04).
 

Notable finding

In an interview, Thomas W. Sedlak, MD, PhD, assistant professor of psychiatry and behavioral health, Johns Hopkins University, Baltimore, said the finding that ACE levels were associated with lower cognition scores is “notable in that we don’t really have any treatments for cognition.

“Antipsychotic drugs treat more of the famous symptoms of hallucinations and delusions and disordered speech, but they don›t really help cognition a whole lot — and too much medicine might even make that worse,” said Dr. Sedlak, who was not involved with the research.

“So it’s interesting to have another biomarker that might relate a symptom of schizophrenia that we don’t really have a good grip on addressing,” he said.

However, he noted that this study is “preliminary,” has not looked at longitudinal changes in ACE in the same patients, and is one of “many” correlation studies.

“I like to say you can pretty much Google any chemical in the body and somebody has a claim about it and schizophrenia,” Dr. Sedlak said.

Nevertheless, the current analysis is “convergent” with past studies on ACE, including those that have found associations between polymorphisms in the enzyme and schizophrenia, he noted.

Moreover, research has shown that ACE facilitates glutamate transmission, specifically via N-methyl-D-aspartate (NMDA) receptors in the prefrontal cortex, “which is probably the brain region most tied to schizophrenia abnormalities,” Dr. Sedlak said.

Patients with schizophrenia appear to prefer long-acting injectable (LAI) antipsychotics, compared with oral versions of these medications, primarily because injectables are more convenient and give individuals more control over their lives, new research shows.

Patients also prefer injections once every 3 months to monthly injections, citing the need for fewer doctor visits and less pain as key reasons. They also reported a preference for deltoid versus gluteal injections, as they were faster and easier to administer, and less embarrassing.

Study investigator Srihari Gopal, MD, senior director at Janssen Research and Development in Titusville, N.J., said in an interview that stigma, which is a “is a really powerful force in mental health treatment,” underlies these findings in terms of the disease itself and its management.

“It’s one of the [key] reasons that schizophrenia patients decide to abandon their drugs and not go to the doctor,” he added.

The study was scheduled to be presented at the Congress of the Schizophrenia International Research Society 2020, but the meeting was canceled because of the coronavirus pandemic.
 

Outdated perceptions

The investigators noted that there is limited information on patient preference with regard to LAI versus oral antipsychotics in the management of schizophrenia.

They also noted that LAIs have been shown to reduce the risk of relapse and rehospitalization because of treatment discontinuation and may help to improve to medication adherence.

However, these medications are still underutilized in clinical practice. Dr. Gopal estimated that only around 1 in 10 patients with schizophrenia in the United States take an LAI, although that figure varies considerably at a global level and is as high as 1 in 2 in Spain.

This is the result of a number of factors that act as potential barriers to LAI use, not the least of which is misconceptions among caregiver and health care professionals about the drugs.

“When I first was in medical school, this was in the 1990s ... there were really only first-generation antipsychotics available in a depot or a long-acting form, and those had very severe side effects,” said Dr. Gopal.

“They would tend to cause all sorts of movement disorders and would make patients feel really drowsy throughout the day, so they really hated taking them,” he said, noting that these depot medications were oil based, which was painful on injection and caused reactions.

While the newer generations of LAIs are water based and have a much-improved adverse effect profile, doctors “on my end of the age spectrum have all those negative connotations and memories in their minds about what these older LAIs were like, ” Dr. Gopal said

“It’s only the newer generation of doctors who were not around at the time that have a more forward-thinking attitude about the newer long-actings.”
 

Differences by country

To assess factors that determine patients’ medication preferences in order to better understand expectations and reduce potential barriers to treatment, the researchers analyzed data on 1,429 patients with schizophrenia who were participants in a double-blind, randomized, noninferiority study of paliperidone palmitate taken monthly versus once every 3 months.

Participants had a mean age of 38.4 years, and 55% were men. The majority (54%) were white, 8% were black or African American, and 38% were from other races. About one-eighth (12%) of the patients were from the United States.

LAIs were preferred by 77% of patients, ranging from 84.2% among whites, 57.7% among blacks, and 71.2% from other races. The highest preference for LAIs was in Europe, at 88%, vs 59.1% in the United States and 70.7% in the rest of the world.

Interestingly, the preference for LAIs in the United States was comparable across different races, at 59.6% among black patients, 58.8% among whites, and 57.1% for other races.

All study participants had a confirmed diagnosis of schizophrenia and a Positive and Negative Syndrome Scale total score of between 70 and 120 at baseline, with worsening symptoms.

They completed the Medication Preference Questionnaire on day 1, day 120, and at the end of the study, with the current analysis focusing on day 1 responses, as that was the only time when patients would not have received any study medication.
 

Patient empowerment key

The most common reason patients cited for preferring LAIs over oral antipsychotics were that they felt healthier (57%), could get back to their favorite activities (56%), and didn’t have to think about taking their medication (54%).

In terms of their personal experiences, patients preferred LAIs to pills because they “are easier for me” (67% vs. 18%) and offered a greater sense of control and relieved them from having to think about taking medication (64% vs. 14%).

Finally, 50% of patients preferred LAI injections once every 3 months versus 38% for monthly and 3% for daily injections. Main reason cited were fewer injections (96%), less pain (84%), and fewer doctor visits (80%).

The preferred site for LAI injection was deltoid muscle over gluteal muscle, at 59%, with faster administration (63%), easier use (51%), and the location being less embarrassing (44%) cited as the primary reasons.

“Overall, patient empowerment and quality of life–related goals were important for patients who preferred LAI antipsychotics,” the investigators noted.

Logistic regression analysis indicated that only race and country were significantly associated with medication preferences, with white patients significantly more likely than others to prefer LAIs versus oral medications (adjusted odds ratio, 2.39; P < .001). U.S. patients were significantly less likely to prefer the drugs than those from other countries (aOR, 0.41; P < .001).

Dr. Gopal added that significant differences in patient preference for LAIs likely have a lot to do with the prevailing attitudes of doctors from different countries, with low LAI use corresponding to “more negative attitudes.”

“Better understanding of patients’ treatment priorities and perspective could help overcome barriers to LAI use and inform best course of personalized schizophrenia treatment for improved patient satisfaction and medication adherence,” the investigators noted.

Approached for comment, Matej Markota, MD, a psychiatrist at the Mayo Clinic in Rochester, Minn., who was not involved with the research, said that he agreed with the findings of the study.

He said in an interview that, in his clinical experience, the convenience of not having to take medications daily is an important factor that drives patient preference for LAI use over oral medications.

The study was funded by Janssen Research & Development. Dr. Gopal reports he is an employee of Janssen Research & Developmentand owns stock/equity in Johnson & Johnson. Dr. Markota has disclosed no relevant financial relationships.

Patients with COVID-19 who have high levels of the steroid hormone cortisol on admission to hospital have a substantially increased risk of dying, U.K. researchers have discovered.

Waljit S. Dhillo, MBBS, PhD, head of the division of diabetes, endocrinology and metabolism at Imperial College London, and colleagues studied 535 patients admitted to major London hospitals. Their article was published online June 18 in Lancet Diabetes & Endocrinology.

“Our analyses show for the first time that patients with COVID-19 mount a marked and appropriate acute cortisol stress response,” said Dr. Dhillo and colleagues.

Moreover, “high cortisol concentrations were associated with increased mortality and a reduced median survival, probably because this is a marker of the severity of illness.”

So measuring cortisol on admission is potentially “another simple marker to use alongside oxygen saturation levels to help us identify which patients need to be admitted immediately, and which may not,” Dr. Dhillo noted in a statement from his institution.

“Having an early indicator of which patients may deteriorate more quickly will help us with providing the best level of care as quickly as possible. In addition, we can also take cortisol levels into account when we are working out how best to treat our patients,” he said.

However, it’s important to note that this means – particularly in the wake of the RECOVERY trial reported last week – that “in the early part of the disease you don’t need steroids,” he said.
 

In contrast to SARS, no adrenal insufficiency with COVID-19

Cortisol levels when healthy and resting are 100-200 nmol/L and nearly zero when sleeping, the researchers explained.

They decided to examine cortisol levels because, although physiological stress from critical illness normally increases levels of the hormone, the prior coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV), had the opposite effect and induced cortisol insufficiency in some patients.

“We would have said we’re not quite sure” what effect SARS-CoV-2 is having on cortisol levels, “so that’s why we collected the data,” Dr. Dhillo said in an interview.

The researchers studied patients admitted to three large London teaching hospitals between March 9 and April 22 with a clinical suspicion of SARS-CoV-2 infection. All patients had a standard set of blood tests, including full blood count, creatinine, C-reactive protein, D-dimer, and serum cortisol.

After exclusions, the team assessed 535 patients admitted over the study period who had baseline cortisol measured within 48 hours of admission.

Of these, 403 patients were diagnosed with COVID-19 based on a positive result on real-time polymerase chain reaction testing (88%) or a strong clinical and radiological suspicion, despite a negative test (12%).

In total, 132 (25%) individuals were not diagnosed with COVID-19.

Patients with COVID-19 were a mean age of 66.3 years, and 59.6% were men.

Mean cortisol concentrations in patients with COVID-19 were significantly higher than those not diagnosed with the virus (619 vs 519 nmol/L; P < .0001).

And by May 8, significantly more patients with COVID-19 died than those without (27.8% vs 6.8%; P < .0001).

Doubling of cortisol levels associated with 40% higher mortality

Multivariate analysis taking into account age, presence of comorbidities, and laboratory tests revealed that a doubling of cortisol concentrations among those with COVID-19 was associated with a significant increase in mortality, at a hazard ratio of 1.42 (P = .014).

And patients with COVID-19 whose baseline cortisol level was >744 nmol/L had a median survival of just 15 days, compared with those with a level ≤744 nmol/L, who had a median survival of 36 days (P < .0001).

The team notes that the cortisol stress responses in their patients with COVID-19 ranged up to 3,241 nmol/L, which is “a marked cortisol stress response, perhaps higher than is observed in patients undergoing major surgery.”

Of interest, there was no interaction between cortisol levels and ethnicity in their study; a subsequent analysis of the data stratified by black, Asian, and other minority ethnicities revealed no significant differences.

The team note that their results will need to be reproduced in other populations.

“Any potential role for cortisol measurement at baseline and later during an inpatient stay with COVID-19 as a prognostic biomarker, either by itself or in combination with other biomarkers, will require validation in a prospective study.”
 

Implications for treatment: Reserve dexamethasone for critically ill

Dr. Dhillo explained that, because their findings indicate that people initially infected with COVID-19 do mount an appropriate stress (cortisol) response, it is important that people properly understand this in the wake of the RECOVERY trial, reported last week.

The trial showed that the widely available steroid dexamethasone significantly reduced mortality among severely ill COVID-19 patients in the intensive care unit when given at a supraphysiologic dose of 6 mg.

But it would be hazardous for anyone to self-medicate with steroids at an early stage of COVID-19 because that would further increase cortisol levels and could suppress the immune system.

“For the average person on the street with COVID-19,” excess steroids will make their symptoms worse, Dr. Dhillo explained, adding this is important to emphasize because dexamethasone, and similar steroids, “are cheap and likely available on the Internet, and so misunderstanding of the RECOVERY trial could have serious implications.”

But once patients are very sick, with “inflammation in their lungs” and are in the intensive care unit, and often on ventilators – which is a very small subgroup of those with COVID-19 – it becomes a very different story, he stressed.

“RECOVERY shows clearly there seems to be a benefit once you need oxygen or are on a ventilator, and that makes sense because [dexamethasone] is going to be an anti-inflammatory,” in this instance when the “lungs are full of water.”

“But in the early days you definitely don’t need it and it could be harmful,” he reiterated.

The study is funded by the U.K. National Institute for Health Research and Medical Research Council. The authors have reported no relevant financial relationships.

Patients with COVID-19 who have high levels of the steroid hormone cortisol on admission to hospital have a substantially increased risk of dying, U.K. researchers have discovered.

Waljit S. Dhillo, MBBS, PhD, head of the division of diabetes, endocrinology and metabolism at Imperial College London, and colleagues studied 535 patients admitted to major London hospitals. Their article was published online June 18 in Lancet Diabetes & Endocrinology.

“Our analyses show for the first time that patients with COVID-19 mount a marked and appropriate acute cortisol stress response,” said Dr. Dhillo and colleagues.

Moreover, “high cortisol concentrations were associated with increased mortality and a reduced median survival, probably because this is a marker of the severity of illness.”

So measuring cortisol on admission is potentially “another simple marker to use alongside oxygen saturation levels to help us identify which patients need to be admitted immediately, and which may not,” Dr. Dhillo noted in a statement from his institution.

“Having an early indicator of which patients may deteriorate more quickly will help us with providing the best level of care as quickly as possible. In addition, we can also take cortisol levels into account when we are working out how best to treat our patients,” he said.

However, it’s important to note that this means – particularly in the wake of the RECOVERY trial reported last week – that “in the early part of the disease you don’t need steroids,” he said.
 

In contrast to SARS, no adrenal insufficiency with COVID-19

Cortisol levels when healthy and resting are 100-200 nmol/L and nearly zero when sleeping, the researchers explained.

They decided to examine cortisol levels because, although physiological stress from critical illness normally increases levels of the hormone, the prior coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV), had the opposite effect and induced cortisol insufficiency in some patients.

“We would have said we’re not quite sure” what effect SARS-CoV-2 is having on cortisol levels, “so that’s why we collected the data,” Dr. Dhillo said in an interview.

The researchers studied patients admitted to three large London teaching hospitals between March 9 and April 22 with a clinical suspicion of SARS-CoV-2 infection. All patients had a standard set of blood tests, including full blood count, creatinine, C-reactive protein, D-dimer, and serum cortisol.

After exclusions, the team assessed 535 patients admitted over the study period who had baseline cortisol measured within 48 hours of admission.

Of these, 403 patients were diagnosed with COVID-19 based on a positive result on real-time polymerase chain reaction testing (88%) or a strong clinical and radiological suspicion, despite a negative test (12%).

The desire to feel better is a major driver for patients with first-episode psychosis (FEP) to turn to cannabis, new research shows.

An analysis of more than 1,300 individuals from six European countries showed patients with FEP were four times more likely than their healthy peers to start smoking cannabis in order to make themselves feel better.

The results also revealed that initiating cannabis use to feel better was associated with a more than tripled risk of being a daily user.

These findings could be used to help tailor treatment interventions, as well as offer an opportunity for psychoeducation – particularly as the reasons for starting cannabis appear to influence frequency of use, study investigator Edoardo Spinazzola, MD, Institute of Psychiatry, Psychology, and Neuroscience at King’s College London, said in an interview.

Patients who start smoking cannabis because their friends or family partakes may benefit from therapies that encourage more “assertiveness” and being “socially comfortable without the substance,” Dr. Spinazzola said, noting that it might also be beneficial to identify the specific cause of the psychological discomfort driving cannabis use, such as depression, and specifically treat that issue.

The results were scheduled to be presented at the Congress of the Schizophrenia International Research Society 2020, but the meeting was canceled because of the coronavirus pandemic.
 

Answering the skeptics

Previous studies suggest that cannabis use can increase risk for psychosis up to 290%, with both frequency of use and potency playing a role, the researchers noted.

However, they added that “skeptics” argue the association could be caused by individuals with psychosis using cannabis as a form of self-medication, the comorbid effect of other psychogenic drugs, or a common genetic vulnerability between cannabis use and psychosis.

The reasons for starting cannabis use remain “largely unexplored,” so the researchers examined records from the European network of national schizophrenia networks studying Gene-Environment Interactions (EU-GEI) database, which includes patients with FEP and healthy individuals acting as controls from France, Italy, the Netherlands, Spain, United Kingdom, and Brazil.

The analysis included 1,347 individuals, of whom 446 had a diagnosis of nonaffective psychosis, 89 had bipolar disorder, and 58 had psychotic depression.

Reasons to start smoking cannabis and patterns of use were determined using the modified version of the Cannabis Experiences Questionnaire.

Results showed that participants who started cannabis to feel better were significantly more likely to be younger, have fewer years of education, to be black or of mixed ethnicity, to be single, or to not be living independently than those who started it because their friends or family were using it (P < .001 for all comparisons).

In addition, 68% of the patients with FEP and 85% of the healthy controls started using cannabis because friends or family were using it. In contrast, 18% of those with FEP versus 5% of controls starting using cannabis to feel better; 13% versus 10%, respectively, started using for “other reasons.”

After taking into account gender, age, ethnicity, and study site, the patients with FEP were significantly more likely than their healthy peers to have started using cannabis to feel better (relative risk ratio, 4.67; P < .001).

Starting to smoke cannabis to feel better versus any other reason was associated with an increased frequency of use in both those with and without FEP, with an RRR of 2.9 for using the drug more than once a week (P = .001) and an RRR of 3.13 for daily use (P < .001). However, the association was stronger in the healthy controls than in those with FEP, with an RRR for daily use of 4.45 versus 3.11, respectively.

The investigators also examined whether there was a link between reasons to start smoking and an individual’s polygenic risk score (PRS) for developing schizophrenia.

Multinomial regression indicated that PRS was not associated with starting cannabis to feel better or because friends were using it. However, there was an association between PRS score and starting the drug because family members were using it (RRR, 0.68; P < .05).
 

Complex association

Gabriella Gobbi, MD, PhD, professor in the neurobiological psychiatry unit, department of psychiatry, at McGill University, Montreal, said the data confirm “what we already know about cannabis.”

She noted that one of the “major causes” of young people starting cannabis is the social environment, while the desire to use the drug to feel better is linked to “the fact that cannabis, in a lot of cases, is used as a self-medication” in order to be calmer and as a relief from anxiety.

There is a “very complex” association between using cannabis to feel better and the self-medication seen with cigarette smoking and alcohol in patients with schizophrenia, said Dr. Gobbi, who was not involved with the research.

“When we talk about [patients using] cannabis, alcohol, and cigarettes, actually we’re talking about the same group of people,” she said.

Although “it is true they say that people look to cigarettes, tobacco, and alcohol to feel happier because they are depressed, the risk of psychosis is only for cannabis,” she added. “It is very low for alcohol and tobacco.”

As a result, Dr. Gobbi said she and her colleagues are “very worried” about the consequences for mental health of the legalization of cannabis consumption in Canada in October 2018 with the passing of the Cannabis Act.

Although there are no firm statistics yet, she has observed that since the law was passed, cannabis use has stabilized at a lower level among adolescents. “But now we have another population of people aged 34 and older that consume cannabis,” she said.

Particularly when considering the impact of higher strength cannabis on psychosis risk, Dr. Gobbi believes the increase in consumption in this age group will result in a “more elevated” risk for mental health issues.

Dr. Spinazzola and Dr. Gobbi have reported no relevant financial relationships.

Adult patients with Burkitt lymphoma can achieve equally sound survival outcomes with dose-adjusted chemotherapy versus high-intensity regimens, but can do so while avoiding the severe toxicities, U.S. study data shows.

Courtesy Wikimedia Commons/Ed Uthman, MD/Creative Commons License

Although Burkitt lymphoma is the most common B-cell non-Hodgkin lymphoma in children, it accounts for only 1% to 2% of adult lymphoma cases.

Highly dose-intensive chemotherapy regimens, developed for children and young adults, have rendered the disease curable. But older patients in particular, and patients with comorbidities such as HIV, can suffer severe adverse effects, as well as late sequelae like second malignancies.

Mark Roschewski, MD, from the lymphoid malignancies branch at the National Cancer Institute in Bethesda, Md., and colleagues therefore examined whether a dose-adjusted regimen would maintain outcomes while reducing toxicities.

Tailoring treatment with etoposide, doxorubicin, and vincristine with prednisone, cyclophosphamide, and rituximab (EPOCH-R) to whether patients had high- or low-risk disease, they achieved 4-year survival rates of higher than 85%.

The research, published by the Journal of Clinical Oncology, also showed that patients taking the regimen, which was well tolerated, had low rates of relapse in the central nervous system.

The team reports that their results with the dose-adjusted regimen “significantly improve on the complexity, cost, and toxicity profile of other regimens,” also highlighting that it is administered on an outpatient basis.

As the outcomes also “compare favorably” with those with high intensity regimens, they say the findings “support our treatment strategies to ameliorate toxicity while maintaining efficacy.”

Importantly, they suggest highly dose-intensive chemotherapy is unnecessary for cure, and carefully defined low-risk patients may be treated with limited chemotherapy.

Dr. Roschewski said in an interview that, in patients aged 40 years and older, dose-adjusted EPOCH-R is “probably the preferred choice,” despite its “weakness” in controlling the disease in patients with active CNS involvement.

However, the “real question” is what to use in younger patients, Dr. Roschewski said, as the “unknown” is whether the additional magnitude of a high-intensity regimen that “gets into the CNS” outweighs the risk of toxicities.

“What was important about our study,” he said, was that patients with CNS involvement “did the worst but it was equally split among patients that died of toxicity and patients that progressed.”

In other words, each choice increases one risk while decreasing another. “So I would have to have that discussion with the patient, and individual patient decisions are typically based on the details,” said Dr. Roschewski.

One issue, however, that could limit the adoption of dose-adjusted EPOCH-R is that, without a randomized study comparing it directly with a high-intensity regimen, clinicians may to stick to what they know.

Dr. Roschewski said that “this is particularly true of more experienced clinicians.”

“They’re less likely, I think, to adopt something else outside of a randomized study because our natural inclination with this disease has always been dose intensity is critical. ... This is a dogma, and to shift from that probably does require a higher level of evidence, at least for some practitioners,” he explained.
 

Further study details

Following a pilot study of dose-adjusted EPOCH-R in 30 adult patients in which the authors say the regimen showed “high efficacy,” they enrolled 113 patients with untreated Burkitt lymphoma at 22 centers between June 2010 and May 2017.

The patients were divided into low-risk and high-risk categories, with low-risk defined as stage 1 or 2 disease, normal lactate dehydrogenase levels, ECOG performance status ≤ 1, and no tumor mass ≥ 7 cm.

High-risk patients were given six cycles of dose-adjusted EPOCH-R (with rituximab on day 1 only) along with CNS prophylaxis or active therapy with intrathecal methotrexate.

In contrast, low-risk patients were given two cycles of dose-adjusted EPOCH-R, with rituximab on days 1 and 5, followed by positron emission tomography.

If that was negative, the patients had one additional treatment cycle and no CNS prophylaxis, but if it was positive, they were given four additional cycles, plus intrathecal methotrexate.

Of the 113 patients enrolled, 79% were male, median age was 49 years, and 62% were aged at least 40 years, including 26% aged at least 60 years.

The team determined that 13% of the patients were of low risk, 87% were high risk, and 11% had cerebrospinal fluid involvement. One-quarter (24.7%) were HIV positive, with a median CD4+ T-cell count of 268 cells/mm³.

The majority (87%) of low-risk patients received three treatment cycles, and 82% of high-risk patents were administered six treatment cycles.

Over a median follow-up of 58.7 months (4.9 years), the 4-year event-free survival (EFS) rate across the whole cohort was 84.5% and overall survival was 87%.

At the time of analysis, all low-risk patients were in remission; among high-risk patients, the 4-year EFS was 82.1% and overall survival was 84.9%.

The team reports that treatment was equally effective across age groups, and irrespective of HIV status and International Prognostic Index risk group.

Only 2% of high-risk patients with no pretreatment evidence of CNS involvement had relapses in the brain parenchyma. Just over half (55%) of patients with cerebrospinal fluid involvement at presentation experienced disease progression or died.

Five patients died of treatment-related toxicity. Grade 3/4 thrombocytopenia occurred during 17% of cycles, and febrile neutropenia was seen during 16%. Tumor lysis syndrome was rare, occurring in 5% of patients.

Next, the researchers are planning on focusing on CNS disease, looking at EPOCH-R as the backbone and adding intrathecal methotrexate and an additional targeted agent with known CNS penetration.

Dr. Roschewski said that is “a very attractive strategy and ... we will initiate enrollment in that study probably in the next couple of months here at the NCI,” he added, noting that it will be an early phase 1 study.

Another issue he identified that “doesn’t get spoken about quite as much but I do think is important is potentially working on supportive care guidelines for how we manage these patients.” Dr. Roschewski explained, “One of the things you see over and over in these Burkitt lymphoma studies is that some patients don’t make it through therapy because they’re so sick at the beginning, and they have certain risks.

“I think simply improving that type of care, independent of what regimen is used, can potentially improve the outcomes across patient groups.”

The study was funded by the National Cancer Institute, National Institutes of Health, AIDS Malignancy Consortium, and the Cancer Therapy Evaluation Program and Lymphoid Malignancies Branch. The authors have disclosed no relevant financial relationships.

Although Burkitt lymphoma is the most common B-cell non-Hodgkin lymphoma in children, it accounts for only 1% to 2% of adult lymphoma cases.

Highly dose-intensive chemotherapy regimens, developed for children and young adults, have rendered the disease curable. But older patients in particular, and patients with comorbidities such as HIV, can suffer severe adverse effects, as well as late sequelae like second malignancies.

Mark Roschewski, MD, from the lymphoid malignancies branch at the National Cancer Institute in Bethesda, Md., and colleagues therefore examined whether a dose-adjusted regimen would maintain outcomes while reducing toxicities.

Tailoring treatment with etoposide, doxorubicin, and vincristine with prednisone, cyclophosphamide, and rituximab (EPOCH-R) to whether patients had high- or low-risk disease, they achieved 4-year survival rates of higher than 85%.

The research, published by the Journal of Clinical Oncology, also showed that patients taking the regimen, which was well tolerated, had low rates of relapse in the central nervous system.

The team reports that their results with the dose-adjusted regimen “significantly improve on the complexity, cost, and toxicity profile of other regimens,” also highlighting that it is administered on an outpatient basis.

As the outcomes also “compare favorably” with those with high intensity regimens, they say the findings “support our treatment strategies to ameliorate toxicity while maintaining efficacy.”

Importantly, they suggest highly dose-intensive chemotherapy is unnecessary for cure, and carefully defined low-risk patients may be treated with limited chemotherapy.

For the first time, weekly cisplatin plus radiotherapy (CDDP+RT) has been shown to be not only less toxic than dosing once every three weeks but to also achieve better outcomes in patients with postoperative squamous cell carcinoma of the head and neck (SCCHN), say Japanese researchers.

These results, from the JCOG1008 trial, suggest the weekly schedule should become the new standard of care in these patients, potentially settling what has been a “contentious” issue.

The research was presented at the 2020 annual meeting of the American Society of Clinical Oncology (abstract 6502), held virtually because of the coronavirus pandemic.

Lead author Naomi Kiyota, MD, PhD, medical oncology and hematology, Cancer Center, Kobe University Hospital, Japan, said the study involving more than 160 high-risk patients with SCCHN demonstrated comparable overall survival in the weekly and three-weekly CDDP+RT groups.

Moreover, it showed that the weekly schedule was associated with better relapse-free and local relapse-free survival, and, in line with previous studies, had a more favorable safety profile.

“This phase II/III study is the first to show that weekly CDDP+RT is noninferior to three-weekly CDDP+RT [and] is a new standard treatment option for these patients,” Dr. Kiyota said.

Study discussant Hisham M. Mehanna, MD, PhD, Warwickshire Head and Neck Clinic, University of Birmingham, UK, described the study as a “significant achievement” that answers “an important question that we’ve been asking for a very long time.”

He said that, despite three-weekly CDDP+RT being the standard treatment in the postoperative setting for SCCHN, there have been “lingering concerns,” as 40% of patients don’t get all three CDDP cycles “and it is toxic.”

Weekly CDDP is, on the other hand, “widely used, although the evidence for it is not as strong,” and has a number of advantages, including that it can be delivered in the outpatient setting and it may be less toxic.

Dr. Mehanna said there was “a surprise” to the current study, in that it was terminated early because it crossed the boundary for non-inferiority because weekly CDDP has better survival than the three-weekly dose; notably, however, superiority was not achieved.

Dr. Mehanna also expressed some reservations over imbalances in the treatment groups that could have meant the three-weekly cohort had an unfavorable prognosis, and said questions remain over longer-term toxicity.
 

‘Contentious issue’

In a highlights session, Nabil F. Saba, MD, director of the head and neck oncology program at Emory University’s Winship Cancer Institute in Atlanta, Georgia, said the dosing of CDDP in these patients has been “a contentious issue.”

One issue has been whether scheduling of CDDP or the cumulative dose achieved is the key determinant of clinical outcome, and he suggested that the superior results seen in the current study can be attributed to the high cumulative dose the investigators achieved in their patients compared with previous investigations.

For Dr. Saba, the take-home message of the trial is that weekly cisplatin “is now, finally, an accepted standard of care in the postoperative high-risk setting, which is a major change at this ASCO meeting.”

Presenting the trial, Dr. Kiyota said, in a recent study (J Clin Oncol. 2017 Dec 8. doi: 10.1200/JCO.2017.74.9457) from the Tata Memorial Hospital, weekly CDDP at 30 mg/m² plus radiotherapy failed to achieve noninferiority to a three-weekly regimen, “albeit with fewer toxicities.”

He suggested that this could be because it was a single-center trial, two different treatment strategies were used, the majority of primary sites were in the oral cavity, and the dose was insufficient.

His team, on the other hand, undertook a randomized trial in which patients with postoperative high-risk SCCHN were recruited from 28 institutions.

The participants, who were aged 20-75 years and had ECOG performance status 0-1, all had pathological stage III/IV disease and a microscopically positive margin and/or extranodal extension.

They were randomly assigned to 100 mg/m² CDDP once every three weeks or weekly 40 mg/m² CDDP, plus radiotherapy at 66 Gy over 33 fractions.

For the intention-to-treat efficacy analysis, 132 patients received three-weekly CDDP+RT and 129 had weekly CDDP+RT, while the per-protocol safety analysis included 129 and 122 patients, respectively.

The median age of the patients was 61-62 years, and 110 patients in both treatment groups were male. Although there was a similar distribution of primary sites and high-risk factors in the two groups, more patients in the weekly group had pathological stage T2 disease (40) than in the three-weekly group (26).

The dose targets were met in both treatment groups. In the three-weekly group, the cumulative dose of CDDP achieved was 280 mg/m^2, and, in the weekly group, it was 239 mg/m².

The second planned interim analysis showed that, over a median follow-up of 2.2 years, 3-year overall survival was estimated at 71.6% in the weekly group versus 59.1% in the three-weekly group (hazard ratio, 0.69).

As this was below the one-sided P value for noninferiority, the data and safety monitoring committee recommended terminating the trial early.

The researchers also found that the 3-year relapse-free survival was higher with weekly CDDP+RT, at 64.5%, vs 53.0% with three-weekly dosing (HR, 0.71).

Local relapse-free survival was also better with weekly dosing, at a 3-year rate of 69.6% versus 59.5% for patients in the three-weekly group (HR, 0.73).

On a planned subgroup analysis, weekly CDDP+RT was nonsignificantly superior to the three-weekly schedule on almost every measure, whether looking at patient age, ECOG performance status, and primary site.

There were also differences in the occurrence of hematologic toxicities between the two groups, with fewer patients given the weekly schedule experiencing grade 3/4 neutropenia than those on the three-weekly dosing. However, there were more cases of any grade thrombocytopenia for patients getting the weekly dosing.

The weekly CDDP+RT regimen demonstrated its lower toxicity when looking at acute nonhematologic adverse events, with fewer occurrences of any grade dysphagia, nausea, hyponatremia, renal impairment, and hearing impairment versus the three-weekly schedule.

The weekly dosing schedule was also associated with lower rates of grade 3/4 dysphagia, nausea, and infection.

The study was funded by the National Cancer Center Research and Development Fund, Japan Agency for Medical Research and Development Fund.

For the first time, weekly cisplatin plus radiotherapy (CDDP+RT) has been shown to be not only less toxic than dosing once every three weeks but to also achieve better outcomes in patients with postoperative squamous cell carcinoma of the head and neck (SCCHN), say Japanese researchers.

These results, from the JCOG1008 trial, suggest the weekly schedule should become the new standard of care in these patients, potentially settling what has been a “contentious” issue.

The research was presented at the 2020 annual meeting of the American Society of Clinical Oncology (abstract 6502), held virtually because of the coronavirus pandemic.

Lead author Naomi Kiyota, MD, PhD, medical oncology and hematology, Cancer Center, Kobe University Hospital, Japan, said the study involving more than 160 high-risk patients with SCCHN demonstrated comparable overall survival in the weekly and three-weekly CDDP+RT groups.

Moreover, it showed that the weekly schedule was associated with better relapse-free and local relapse-free survival, and, in line with previous studies, had a more favorable safety profile.

“This phase II/III study is the first to show that weekly CDDP+RT is noninferior to three-weekly CDDP+RT [and] is a new standard treatment option for these patients,” Dr. Kiyota said.

Study discussant Hisham M. Mehanna, MD, PhD, Warwickshire Head and Neck Clinic, University of Birmingham, UK, described the study as a “significant achievement” that answers “an important question that we’ve been asking for a very long time.”

He said that, despite three-weekly CDDP+RT being the standard treatment in the postoperative setting for SCCHN, there have been “lingering concerns,” as 40% of patients don’t get all three CDDP cycles “and it is toxic.”

Weekly CDDP is, on the other hand, “widely used, although the evidence for it is not as strong,” and has a number of advantages, including that it can be delivered in the outpatient setting and it may be less toxic.

Dr. Mehanna said there was “a surprise” to the current study, in that it was terminated early because it crossed the boundary for non-inferiority because weekly CDDP has better survival than the three-weekly dose; notably, however, superiority was not achieved.

Dr. Mehanna also expressed some reservations over imbalances in the treatment groups that could have meant the three-weekly cohort had an unfavorable prognosis, and said questions remain over longer-term toxicity.
 

‘Contentious issue’

In a highlights session, Nabil F. Saba, MD, director of the head and neck oncology program at Emory University’s Winship Cancer Institute in Atlanta, Georgia, said the dosing of CDDP in these patients has been “a contentious issue.”

One issue has been whether scheduling of CDDP or the cumulative dose achieved is the key determinant of clinical outcome, and he suggested that the superior results seen in the current study can be attributed to the high cumulative dose the investigators achieved in their patients compared with previous investigations.

For Dr. Saba, the take-home message of the trial is that weekly cisplatin “is now, finally, an accepted standard of care in the postoperative high-risk setting, which is a major change at this ASCO meeting.”

Presenting the trial, Dr. Kiyota said, in a recent study (J Clin Oncol. 2017 Dec 8. doi: 10.1200/JCO.2017.74.9457) from the Tata Memorial Hospital, weekly CDDP at 30 mg/m² plus radiotherapy failed to achieve noninferiority to a three-weekly regimen, “albeit with fewer toxicities.”

He suggested that this could be because it was a single-center trial, two different treatment strategies were used, the majority of primary sites were in the oral cavity, and the dose was insufficient.

His team, on the other hand, undertook a randomized trial in which patients with postoperative high-risk SCCHN were recruited from 28 institutions.

The participants, who were aged 20-75 years and had ECOG performance status 0-1, all had pathological stage III/IV disease and a microscopically positive margin and/or extranodal extension.

They were randomly assigned to 100 mg/m² CDDP once every three weeks or weekly 40 mg/m² CDDP, plus radiotherapy at 66 Gy over 33 fractions.

For the intention-to-treat efficacy analysis, 132 patients received three-weekly CDDP+RT and 129 had weekly CDDP+RT, while the per-protocol safety analysis included 129 and 122 patients, respectively.

The median age of the patients was 61-62 years, and 110 patients in both treatment groups were male. Although there was a similar distribution of primary sites and high-risk factors in the two groups, more patients in the weekly group had pathological stage T2 disease (40) than in the three-weekly group (26).

The dose targets were met in both treatment groups. In the three-weekly group, the cumulative dose of CDDP achieved was 280 mg/m^2, and, in the weekly group, it was 239 mg/m².

The second planned interim analysis showed that, over a median follow-up of 2.2 years, 3-year overall survival was estimated at 71.6% in the weekly group versus 59.1% in the three-weekly group (hazard ratio, 0.69).

As this was below the one-sided P value for noninferiority, the data and safety monitoring committee recommended terminating the trial early.

The researchers also found that the 3-year relapse-free survival was higher with weekly CDDP+RT, at 64.5%, vs 53.0% with three-weekly dosing (HR, 0.71).

Local relapse-free survival was also better with weekly dosing, at a 3-year rate of 69.6% versus 59.5% for patients in the three-weekly group (HR, 0.73).

On a planned subgroup analysis, weekly CDDP+RT was nonsignificantly superior to the three-weekly schedule on almost every measure, whether looking at patient age, ECOG performance status, and primary site.

There were also differences in the occurrence of hematologic toxicities between the two groups, with fewer patients given the weekly schedule experiencing grade 3/4 neutropenia than those on the three-weekly dosing. However, there were more cases of any grade thrombocytopenia for patients getting the weekly dosing.

The weekly CDDP+RT regimen demonstrated its lower toxicity when looking at acute nonhematologic adverse events, with fewer occurrences of any grade dysphagia, nausea, hyponatremia, renal impairment, and hearing impairment versus the three-weekly schedule.

The weekly dosing schedule was also associated with lower rates of grade 3/4 dysphagia, nausea, and infection.

The study was funded by the National Cancer Center Research and Development Fund, Japan Agency for Medical Research and Development Fund.

Continuing adjuvant imatinib (Gleevec, Novartis) for 3 years rather than stopping at 1 year in patients with high-risk gastrointestinal stromal tumors (GIST) could halve the death rate over 10 years, phase 3 trial data suggest.

The most recent analysis of the SSGXVIII/AIO trial shows that, in about 400 patients who underwent surgery and had a high estimated risk of recurrence, there was a 50% increase in overall survival with longer treatment at 10 years on an efficacy analysis.

Moreover, there was a 30% improvement in recurrence-free survival (RFS) with 3 years vs 1 year of imatinib, with an even greater benefit seen in patients with a common tumor mutation.

The research was presented at the 2020 annual meeting of the American Society of Clinical Oncology (abstract 11503), held virtually because of the coronavirus pandemic.

Lead author Peter Reichardt, MD, Helios Klinikum Berlin-Buch, Berlin, Germany, said the results show that “3 years of adjuvant imatinib is highly superior” in terms of RFS and overall survival to 1 year of treatment.

“Overall, approximately 50% of deaths can be avoided during the first 10 years of follow-up after surgery with the longer adjuvant imatinib treatment.”

Study discussant Giovanni Grignani, MD, Division of Medical Oncology, Candiolo Cancer Institute, FPO-IRCCS, Turin, Italy, said that the “burning question” in the sarcoma space is: “Can we improve overall survival by reducing the risk of relapse with a perioperative treatment?

“We would like to able to identify patients for whom the cost of toxicity is paid off by an improvement in their outcome,” he added, noting that this is not achievable “and this is why perioperative treatment is so controversial in oncology.”

Grignani said the picture is a little different for GIST, as the relapse risk is unevenly distributed, the activity of imatinib is “extraordinary,” and the drug toxicity is “certainly bearable but not negligible.”

RFS is, however, affected by the inability of imatinib to eradicate resistant clones left behind by surgery, and replication resumes once the drug is stopped.

The current study nevertheless shows that overall survival “clearly favors 3-year imatinib therapy…with an impressive median follow-up of 119 months [10 years],” commented Patrick Leavey, MD, University of Texas Southwestern Medical Center, Dallas, in a highlights session.

He added that, in GIST, what might be considered “new progress” with the findings “is clarity over the length of imatinib therapy, which ... seems to be safe.”

Reichardt began by noting that several large randomized trials over the past decade have shown that adjuvant imatinib improves both RFS and overall survival.

However, “it is unknown whether imatinib improves overall survival after extended follow-up,” in addition to which “little is known about the long-term safety” of the drug in this setting.

To offer further insights, the protocol of SSGXVIII/AIO was amended in April 2017 to allow for a third analysis to be carried out once the last patient who entered the trial has been followed up for 10 years.
 

More Details

Reichardt recalled that the study, which was an open-label, multicenter phase 3 trial, involved GIST patients who were randomly assigned following surgery in a 1:1 fashion to imatinib for either 12 months or 36 months.

The patients were required to have a high-risk of recurrence, defined as at least one of the following:

• Tumor size >10 cm
• Tumor mitosis count >10/50 on high-powered microscopy (HPF)
• Tumor size >5 cm and mitosis count >5/50 HPF
• Tumor rupture, either spontaneously or at surgery.

Four hundred patients were recruited between February 2004 and September 2008, and 181 patients who were randomly assigned to 12 months of imatinib and 177 to 36 months were included in the efficacy analysis.

The median age of the patients was approximately 61 years, and half were female. The treatment groups were well-balanced in terms of their baseline characteristics.

Of note, 69% of patients in the 1-year treatment group and 71% of those given imatinib for 3 years had a detectable mutation in the KIT exon 11 site. The mean mitosis count was 10/50 and 8/50, respectively.

Over a median follow-up of 119 months (9 years, 11 months), 53% of 1-year treatment patients experienced a recurrence event, and 30% died, of whom 82% died with metastatic GIST.

In the 3-year treatment group, 44% experienced a recurrence event, and 18% died, with 83% of deaths from metastatic GIST.

On intention-to-treat analysis, RFS at 10 years was significantly higher with 3 years of imatinib than with 1 year, at 53% vs 42% (hazard ratio [HR], 0.66; P = .003).

Overall survival at 10 years was also higher with longer imatinib treatment, at 79% with 3 years of therapy vs 65% with 1 year (HR, 0.55; P = .004).

The team found on subgroup analysis that RFS was significantly better with 3-year than 1-year imatinib in patients with:

• A local mitotic count >10 (HR = 0.42)
• A central mitotic count >10 (HR = 0.50)
• A KIT exon 11 tumor mutation (HR = 0.57).

On the efficacy analysis, which included patients who signed informed consent, had GIST at pathology review, and no overt metastases at study entry, the HR for RFS with 3-year vs 1-year therapy was 0.70, whereas the HR for overall survival was 0.50.

Patients treated with imatinib for 3 years had a higher rate of any new cancer during follow-up, at 17%, vs 12% for those treated with imatinib for 1 year. Prostate cancer was the most common form of the disease in both groups.

Cardiac events were, in contrast, evenly distributed between the two groups, with 5% of 3-year patients and 6% of 1-year patients experiencing an event.

The study was funded by Novartis.

The BEACON study tested both a doublet and a triplet of drugs for patients with previously treated BRAF V600E–mutated metastatic colorectal cancer (CRC).

New results from that trial, with an updated survival analysis, show that the doublet is sufficient and that patients can safely be treated with a combination of the BRAF inhibitor encorafenib (Braftovi, Array BioPharma) and the EGFR inhibitor monoclonal antibody cetuximab (Erbitux, Eli Lilly).

This means that the increased toxicity from the addition of the MEK inhibitor binimetinib (Mektovi, Array BioPharma) can be avoided and that good outcomes can be maintained.

The new results were presented as part of the virtual scientific program of the 2020 American Society of Clinical Oncology annual meeting.

Study discussant Michael S. Lee, MD, from the University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, said he “would consider encorafenib and cetuximab now the standard of care in the second line and beyond in BRAF-mutant colorectal cancer.

“I would give the doublet rather than the triplet because of the comparable survival and better side effect profile,” he said.

“This is immediately practice changing, given the FDA approval of encorafenib and cetuximab,” commented Autumn J. McRee, MD, UNC Lineberger Comprehensive Cancer Center.

This is a “clinically relevant” trial, and it demonstrates that the “poorest prognostic group in colorectal cancer now has viable options,” she said at a Highlights of the Day session.

“We will await the results of the ANCHOR-CRC trial to see if we should be using this targeted approach in earlier lines of therapy,” she added.
 

New survival data

The primary analysis of BEACON CRC, presented at the 2019 World Conference on Gastrointestinal Cancer, showed that use of the triplet therapy was associated with a 48% improvement in overall survival in comparison with standard chemotherapy.

Although that was also linked to improved quality of life, questions have been raised as to whether the benefits are worth the cost, and one commentator singled the study out for harsh criticism.

Scott Kopetz, MD, PhD, from the University of Texas MD Anderson Cancer Center, Houston, presented the updated survival results from BEACON CRC, which included data from an additional 6 months of follow-up.

“We know that the V600E mutation in BRAF occurs in about 10%-15% of patients and is associated with a poor prognosis,” Dr. Kopetz commented.

“BRAF inhibitors alone are not effective,” he noted. He said preclinical models point toward an approach that targets multiple pathways, including BRAF, MEK, and EGFR.

The BEACON study had three arms, each with 205 patients, as follows:

• Encorafenib plus binimetinib plus cetuximab
• Encorafenib plus cetixumab
• A control arm of FOLFIRI plus cetuximab or irinotecan plus cetuximab.

The three arms of the trial were relatively well balanced with respect to patient characteristics, Dr. Kopetz commented. The median age of the patients ranged from 60 to 62 years, and 48%-57% of the patients were women.

Of note, between 5% and 10% of the cases were characterized by high microsatellite instability, and 34%-35% of patients had received more than one prior line of therapy.

The data now presented at ASCO represent a post hoc updated analysis that includes 6 months of additional follow-up since the primary analysis was presented, Dr. Kopetz explained.

After a median follow-up of 12.8 months, 13% of triplet therapy patients, 14% of those who received doublet therapy, and 3% of control patients were still on treatment.

The updated analysis shows that median overall survival with the doublet therapy was 9.3 months versus 5.9 months for the control group (hazard ratio, 0.61). The benefit was seen across all subgroups, including those based on the number of prior regimens.

Dr. Kopetz pointed out that overall survival was numerically superior to that seen in the primary analysis, which was 8.4 months.

The updated survival analysis for the triplet therapy indicated that the median overall survival was 9.3 months versus 5.9 months in the control arm (HR, 0.60). Again, this was consistent across subgroups.

In the primary analysis, the median overall survival with the triplet therapy was 9.0 months.

The team also compared the triplet and doublet therapies, finding that, “in contrast to what was seen in the primary analysis ... we see numerically identical median overall survival with the two arms.” The result was sustained across subgroups.

However, there were indications that there may be survival benefits with the triplet in certain patient subgroups, including those with Eastern Cooperative Oncology Group performance status 1, those in whom three or more organs are involved, those with higher baseline levels of C-reactive protein, and those with partially resected or unresected disease.

Progression-free survival was comparable between the two treatment groups, at 4.5 months with the triplet therapy and 4.3 months with the doublet, compared with just 1.5 months in the control arm.

The updated analysis also showed that the objective response rate was 27% with triplet therapy versus 20% with the doublet and 2% in the control arm. In both the doublet and triplet arms, the majority of responses were partial.

With regard to safety, Dr. Kopetz said that the updated data regarding adverse events were in general “consistent with the previously reported safety profile.”

He added it is “notable” that the triplet therapy “had slightly higher rates of GI toxicity and anemia,” which was not seen with the doublet, something that is “again associated with the known safety profile of a MEK inhibitor.”

The study was funded by Pfizer. Dr. Kopetz has stock and other ownership interests with numerous pharmaceutical companies. Other authors, as well as Dr. Lee and Dr. McRee, have also reported relevant financial relationships.

The BEACON study tested both a doublet and a triplet of drugs for patients with previously treated BRAF V600E–mutated metastatic colorectal cancer (CRC).

New results from that trial, with an updated survival analysis, show that the doublet is sufficient and that patients can safely be treated with a combination of the BRAF inhibitor encorafenib (Braftovi, Array BioPharma) and the EGFR inhibitor monoclonal antibody cetuximab (Erbitux, Eli Lilly).

This means that the increased toxicity from the addition of the MEK inhibitor binimetinib (Mektovi, Array BioPharma) can be avoided and that good outcomes can be maintained.

The new results were presented as part of the virtual scientific program of the 2020 American Society of Clinical Oncology annual meeting.

Study discussant Michael S. Lee, MD, from the University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, said he “would consider encorafenib and cetuximab now the standard of care in the second line and beyond in BRAF-mutant colorectal cancer.

“I would give the doublet rather than the triplet because of the comparable survival and better side effect profile,” he said.

“This is immediately practice changing, given the FDA approval of encorafenib and cetuximab,” commented Autumn J. McRee, MD, UNC Lineberger Comprehensive Cancer Center.

This is a “clinically relevant” trial, and it demonstrates that the “poorest prognostic group in colorectal cancer now has viable options,” she said at a Highlights of the Day session.

“We will await the results of the ANCHOR-CRC trial to see if we should be using this targeted approach in earlier lines of therapy,” she added.
 

New survival data

The primary analysis of BEACON CRC, presented at the 2019 World Conference on Gastrointestinal Cancer, showed that use of the triplet therapy was associated with a 48% improvement in overall survival in comparison with standard chemotherapy.

Although that was also linked to improved quality of life, questions have been raised as to whether the benefits are worth the cost, and one commentator singled the study out for harsh criticism.

Scott Kopetz, MD, PhD, from the University of Texas MD Anderson Cancer Center, Houston, presented the updated survival results from BEACON CRC, which included data from an additional 6 months of follow-up.

“We know that the V600E mutation in BRAF occurs in about 10%-15% of patients and is associated with a poor prognosis,” Dr. Kopetz commented.

“BRAF inhibitors alone are not effective,” he noted. He said preclinical models point toward an approach that targets multiple pathways, including BRAF, MEK, and EGFR.

The BEACON study had three arms, each with 205 patients, as follows:

• Encorafenib plus binimetinib plus cetuximab
• Encorafenib plus cetixumab
• A control arm of FOLFIRI plus cetuximab or irinotecan plus cetuximab.

The three arms of the trial were relatively well balanced with respect to patient characteristics, Dr. Kopetz commented. The median age of the patients ranged from 60 to 62 years, and 48%-57% of the patients were women.

Of note, between 5% and 10% of the cases were characterized by high microsatellite instability, and 34%-35% of patients had received more than one prior line of therapy.

The data now presented at ASCO represent a post hoc updated analysis that includes 6 months of additional follow-up since the primary analysis was presented, Dr. Kopetz explained.

After a median follow-up of 12.8 months, 13% of triplet therapy patients, 14% of those who received doublet therapy, and 3% of control patients were still on treatment.

The updated analysis shows that median overall survival with the doublet therapy was 9.3 months versus 5.9 months for the control group (hazard ratio, 0.61). The benefit was seen across all subgroups, including those based on the number of prior regimens.

Testing for HER2 in patients with colorectal cancer (CRC) should become a new standard of care, say experts discussing new results from a phase 2 trial showing benefit with trastuzumab deruxtecan (T-DXd, marketed as Enhertu, AstraZeneca/Daiichi Sankyo).

This drug is approved in the United States for use in the treatment of unresectable or metastatic HER2-positive breast cancer in patients who have already received two or more prior anti–HER2-based regimens in the metastatic setting.

Results come from a phase 2 study, dubbed DESTINY-CRC01, in patients with previously treated HER2+ advanced CRC.

The results show that, in patients with the highest degree of HER2 positivity, T-DXd was associated with an objective response rate of over 45% and a median progression-free survival (PFS) of almost 7 months.

They “demonstrate, in our opinion, the potential of T-DXd as a treatment option” for patients with advanced HER2-positive colorectal cancer that is refractory to standard therapies, said lead investigator Salvatore Siena, MD, from Niguarda Cancer Center, in Milan, Italy.

He presented the results at the 2020 annual meeting of the American Society of Clinical Oncology, held virtually because of the coronavirus pandemic.

At the same time, results from another study, this time in gastric cancer patients, were published online in the New England Journal of Medicine.
 

Interstitial lung disease as adverse event

The safety profile of T-DXd seen in the colorectal trial “is consistent with what has been previously reported,” said Siena, adding that most of the adverse events were low grade. But he noted there was also a serious adverse effect – interstitial lung disease (ILD). This occurred in 6% of patients, two of whom died. This is “an important risk and requires careful monitoring and proper intervention,” he emphasized.

The ILD adverse effect in this study is “a concern…and something to consider,” commented discussant for the study Michael S. Lee, MD, Lineberger Comprehensive Cancer Center, University of North Carolina, Chapel Hill. But he added that these are the “the best data so far for subsequent anti-HER2 therapy in colorectal cancer”.

Also, the dose of drug used in this trial was higher than that approved for breast cancer, and the incidence of ILD “begs the question of whether we should be using a lower dose in this patient population,” said Autumn J. McRee, MD, also from Lineberger, in a highlights session at the meeting.

“The question here really is whether an HER2-specific approach is superior to what we would offer to these patients in the standard of care setting,” McRee said.

She noted that the patients in DESTINY-CRC01 were “heavily pretreated…and if you think about what our options are in the refractory setting, we do have two approved treatments: regorafenib [Stivarga, Bayer] and TAS-102 [Lonsurf, Taiho Oncology].”

The current data suggest, however, that T-DXd is associated with a trend toward higher response rates and improved survival outcomes, as well as lower monthly costs.

“Without a doubt, this trial is clinically relevant,” she said, adding that it’s “important not to miss these patients.”

“They are rare…but I would argue that testing for HER2 amplification in colorectal cancer should be considered standard of care,” she said.

She added that, based on the current evidence, the trial “may be” practice changing, although it is “still to be determined how to sequence HER2 targeted therapies.”
 

Study details

The trial was conducted in 78 patients with previously treated unresectable and/or metastatic CRC that was HER2 expressing, RAS/BRAF wild type, and patients had to have received at least two prior regimens, including prior anti-HER2 treatment. Patients with current or suspected ILD were excluded.

Patients were divided into three cohorts based on the degree of HER2 positivity:

• HER2+ with immunohistochemistry (IHC) scoring 3+ or IHC2+/in-situ-hybridization (ISH)+ (cohort A, n = 53)
• HER2 IHC2+/ISH– (cohort B, n = 7)
• HER2 IHC1+ (cohort C, n = 18)

All patients received T-DXd at 6.4 mg/kg intravenously every 3 weeks until progression or intolerable toxicity.

Across the three cohorts, the median age was 58.5 years, and nearly half (47.4%) of patients were female. The vast majority (98.7%) of patents had ECOG performance status 0 or 1, and the primary tumor site was the left colon or rectum in 89.7%.

Siena noted that “the median number of prior lines of standard therapies was four, ranging from two to 11.” All patients had previously received irinotecan and oxaliplatin, and 20.5% had received an anti-HER2 drug.

At the data cutoff on August 9, 2019, 38.5% of patients remained on treatment. The reason for discontinuation was progressive disease in 41%, and clinical progression in 9%.

Siena reported that the overall response rate, as confirmed by independent central review, was 45.3% in cohort A, with all but one of the 24 responders having a partial response. No responses were recorded in cohorts B and C.

Stable disease was seen in 37.7% of cohort A patients, giving a disease control rate of 83%. The median duration of response was not reached.

Median PFS was 6.9 months in cohort A, and the medial overall survival was not reached.

In terms of safety, 50.9% of patients in cohort A and 48.7% patients overall experienced drug-related treatment emergent adverse events, with 22.6% and 17.9%, respectively, having serious drug-related events.

The most common treatment-emergent adverse events were nausea, anemia, reduced neutrophil count, fatigue, and decreased appetite.

There were two deaths related to the study drug, as determined by investigator assessment: one from pneumonitis and one as a result of ILD, with both occurring in cohort A.

Looking specifically at ILD, Siena said there were five events – two grade 2, one grade 3, and two grade 5 – at a median time to reported onset of 80 days. All patients received corticosteroids, as per the study protocol, and two recovered.

Study discussant Lee commented that biomarker testing, such as for HER2, “is part of our standard of care for colorectal cancer,” although studies such as the current one are providing new data to “better refine” treatment approaches.

Lee said that, overall, T-DXd had a response rate and PFS survival “that looked similar to prior data from previous single arm phase 2 studies,” with response rates generally ranging from 30% to 50%, “and this compares favorably with other standard of care options” for chemotherapy-refractory patients.

Nevertheless, there are several ongoing questions related to the treatment of HER2 amplified metastatic CRC patients, some of which are being addressed in the ongoing SWOG S1613 study.

Lee said that, for now, he would recommend that patients with HER2 amplification enroll in a clinical trial, if possible. “However, if that’s not feasible, there are a range of options to consider,” including trastuzumab plus lapatinib (Tykerb, Novartis), or trastuzumab plus pembrolizumab (Keytruda, Merck).

However, “none of these options are FDA approved so there will be issues potentially with financial toxicity and other regulatory issues,” he said.

The study was funded by Daiichi Sankyo Co, Ltd.

• HER2 IHC1+ (cohort C, n = 18)

All patients received T-DXd at 6.4 mg/kg intravenously every 3 weeks until progression or intolerable toxicity.

Across the three cohorts, the median age was 58.5 years, and nearly half (47.4%) of patients were female. The vast majority (98.7%) of patents had ECOG performance status 0 or 1, and the primary tumor site was the left colon or rectum in 89.7%.

Siena noted that “the median number of prior lines of standard therapies was four, ranging from two to 11.” All patients had previously received irinotecan and oxaliplatin, and 20.5% had received an anti-HER2 drug.

At the data cutoff on August 9, 2019, 38.5% of patients remained on treatment. The reason for discontinuation was progressive disease in 41%, and clinical progression in 9%.

Siena reported that the overall response rate, as confirmed by independent central review, was 45.3% in cohort A, with all but one of the 24 responders having a partial response. No responses were recorded in cohorts B and C.

Stable disease was seen in 37.7% of cohort A patients, giving a disease control rate of 83%. The median duration of response was not reached.

Median PFS was 6.9 months in cohort A, and the medial overall survival was not reached.

In terms of safety, 50.9% of patients in cohort A and 48.7% patients overall experienced drug-related treatment emergent adverse events, with 22.6% and 17.9%, respectively, having serious drug-related events.

The most common treatment-emergent adverse events were nausea, anemia, reduced neutrophil count, fatigue, and decreased appetite.

There were two deaths related to the study drug, as determined by investigator assessment: one from pneumonitis and one as a result of ILD, with both occurring in cohort A.

Looking specifically at ILD, Siena said there were five events – two grade 2, one grade 3, and two grade 5 – at a median time to reported onset of 80 days. All patients received corticosteroids, as per the study protocol, and two recovered.

Study discussant Lee commented that biomarker testing, such as for HER2, “is part of our standard of care for colorectal cancer,” although studies such as the current one are providing new data to “better refine” treatment approaches.

Lee said that, overall, T-DXd had a response rate and PFS survival “that looked similar to prior data from previous single arm phase 2 studies,” with response rates generally ranging from 30% to 50%, “and this compares favorably with other standard of care options” for chemotherapy-refractory patients.

Nevertheless, there are several ongoing questions related to the treatment of HER2 amplified metastatic CRC patients, some of which are being addressed in the ongoing SWOG S1613 study.

Lee said that, for now, he would recommend that patients with HER2 amplification enroll in a clinical trial, if possible. “However, if that’s not feasible, there are a range of options to consider,” including trastuzumab plus lapatinib (Tykerb, Novartis), or trastuzumab plus pembrolizumab (Keytruda, Merck).

However, “none of these options are FDA approved so there will be issues potentially with financial toxicity and other regulatory issues,” he said.
