Pembrolizumab improves event-free survival in early TNBC
The original trial data in more than 1,100 patients with early-stage TNBC indicated that adding pembrolizumab to chemotherapy prior to surgery and giving the drug for a year afterward improves event-free survival (EFS) over placebo by 37%.
Now, the researchers conducted a series of prespecified sensitivity and subgroup analyses, finding remarkably consistent EFS outcomes whether considering the addition of adjuvant chemotherapy, positive surgical margins, or disease characteristics such as nodal status and disease stage.
The analyses showed that the benefit with pembrolizumab over placebo was “robust,” said study presenter Peter Schmid, MD, PhD, Centre for Experimental Cancer Medicine, Barts Cancer Institute, Queen Mary University of London.
“These results further support pembrolizumab plus platinum-containing neoadjuvant chemotherapy followed by adjuvant pembrolizumab after surgery as a new standard of care treatment regimen for patients with high-risk, early-stage TNBC,” he said.
The research was presented at the San Antonio Breast Cancer Symposium on Dec. 7.
Hope S. Rugo, MD, who was invited to comment on the findings, noted that, while the sensitivity analyses showed the benefit with pembrolizumab was seen across the board, the numbers in each group of interest were “very small, making any impact unlikely.”
She continued that there also remain a number of unanswered questions, chief among them being: “Does everybody need a checkpoint inhibitor? Perhaps studies ... could help us understand which patients might do well with chemotherapy alone.”
Dr. Rugo, who is professor of medicine in the division of hematology and oncology at the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco, , added that “we need to understand the balance of risk and toxicity” asking whether there are patients whose risk of an immunotoxicity is “so high that we should not give them a checkpoint inhibitor.”
It is not clear what constitutes the optimal chemotherapy backbone. “Does everybody need carboplatin? Does everyone need a year of pembrolizumab, even with a pathologic complete response given the intriguing data from GeparNUEVO and previously the I-SPY trial?” she asked.
“Of course, we don’t know the answers to those questions,” she said, but it is nevertheless possible to draw a roadmap for the treatment of early TNBC, although the choice of adjuvant therapy following surgery is less clear.
Dr. Rugo conducted a Twitter poll to canvas opinion on what to give to patients following surgery, depending on whether or not they have a pathological complete response.
At 73%, most of almost 200 respondents said patients with a pathological complete response should continue pembrolizumab for 1 year, while 72% said that patients without a pathological complete response should receive combination therapy of pembrolizumab and either capecitabine or olaparib, depending on mutational status.
Dr. Schmid began his presentation by noting that KEYNOTE-522 was the first prospective, randomized, phase 3 trial of pembrolizumab in early TNBC in the neoadjuvant and adjuvant setting.
Previously presented results showed that adding neoadjuvant pembrolizumab to chemotherapy was associated with a clinically meaningful increase in pathological complete response, while continuing with adjuvant chemotherapy after surgery led to a clinically meaningful improvement in EFS.
Consequently, the Food and Drug Administration approved pembrolizumab in this setting for patients with high-risk early-stage TNBC.
He reminded the audience that the trial included 1,174 patients randomized 2:1 to pembrolizumab or placebo every 3 weeks alongside eight cycles of chemotherapy, followed by pembrolizumab over placebo alone for up to nine cycles after undergoing definitive surgery.
After a median follow-up of 39.1 months, 15.7% of patients treated with pembrolizumab experienced an event versus 23.9% of those in the placebo group, at a hazard ratio of 0.63 (P = .00031). At 36 months, the EFS rate was 84.5% with pembrolizumab and 76.8% in patients treated with placebo.
Dr. Schmid said that they then performed five prespecified sensitivity analyses, which revealed that the results were “consistent with the primary EFS in all five sensitivity analyses, showing the robustnesses of the event-free survival benefit in the pembrolizumab arm.”
The first analysis, he continued, is of “particular interest as it considered the impact of postsurgery new anticancer therapy. For example, the use of adjuvant capecitabine.”
Censoring 31 patients from the pembrolizumab arm who received the drug and 13 of those given placebo, the team found that the hazard ratio for EFS for pembrolizumab versus placebo was 0.64.
Removing “positive margin at last surgery” as part of the definition of EFS also did not change the results substantially, with the HR for EFS for pembrolizumab versus placebo at 0.65.
Subgroup analysis revealed “consistent EFS results,” Dr. Schmid said, irrespective of whether stratifying the patients by nodal status, overall disease stage, menopausal status, HER2 status, or lactate dehydrogenase levels.
While patients in both treatment arms who had nodal involvement had worse outcomes than those without, those in the pembrolizumab arm “still had improved outcomes, compared with placebo, suggesting that it provides benefit regardless of nodal status.”
“Similarly, the EFS benefit with pembrolizumab was irrespective of disease stage,” Dr. Schmid said. Although the EFS improvement was greater in patients with stage II rather than III disease, at a HR of 0.60 versus 0.68, it highlights “the importance of early intervention.”
He said that the “rate of adverse events with pembrolizumab was low, especially in the adjuvant setting.”
Following his presentation, Dr. Schmid was asked whether he would consider retrying immunotherapy in patients after progression on pembrolizumab.
He replied that this is currently a “data-free zone.”
However, he said: “If a patient responded immunotherapy initially, had a disease-free interval and then has recurrence, then I would consider, if the patient is PD-L1 [programmed death–ligand 1] positive, at that time to add immunotherapy. We can’t say whether those patients will derive the same benefit” as that seen in randomized controlled trials in later stage TNBC, he added, “but there is, in my opinion, little to lose, especially if we have already established the patient tolerates immunotherapy well in that setting.”
Dr. Schmid continued that he “personally found it reassuring” that, in the current study, even patients without a complete pathological response “still showed a substantially better event-free survival compared to patients without immunotherapy, so I personally would consider immunotherapy for those patients when they relapse but we can discuss what the optimal disease-free interval is.”
The study was funded by Merck Sharp and Dohme. Both Dr. Rugo and Dr. Schmid reported relationships numerous pharmaceutical companies.

Genomic instability varies between breast cancer subtypes
More than 1,000 patients with TNBC, ER+ breast cancer, or ovarian cancer from five cohorts were examined for genomic instability scores (GIS) and the presence of BRCA deficiency, which showed that, while GIS was similar in BRCA-deficient TNBC and ovarian cancer, it was significantly different in ER+ breast cancer.
The analysis, presented at the San Antonio Breast Cancer Symposium, showed that the genomic instability scores threshold, which could be used to dictate a patient’s treatment, should be lower for ER+ breast cancer than for TNBC.
“This indicates that different GIS thresholds are appropriate for breast cancer subtypes, and that the GIS threshold developed for ovarian caner is not appropriate for ER+ breast cancer,” said lead author Kirsten Timms, PhD, from Myriad Genetics.
This, she noted, is “consistent with the fact that ovarian cancer and TNBC are known to have similar molecular signatures.”
The researchers suggest that the “more inclusive” thresholds assessed in the study should be examined in further studies “to determine whether these cutoffs are associated with a benefit from treatment with DNA-targeting agents,” such as poly (ADP-ribose) polymerase (PARP) inhibitors.
Thomas P. Slavin, MD, chief medical officer at Myriad Genetics, said in an interview that there is “not a one size fits all” for GIS thresholds.
“When you look at ER+ breast cancer you see we need a different cutoff because it’s probably not as driven by homologous recombination deficiency [HRD], as least as a whole, compared to the other two,” he said. “There’s a little less genomic instability.”
He continued that their results suggest around half of TNBC patients have a GIS score that indicates the presence of significant HRD, which is “spot on for what we see with ovarian cancer” and “those people should respond pretty well to PARP-inhibitor therapies,” which is currently being investigated in clinical trials.
“But even in the ER+ group, when we look at the thresholds we used in this research, still about a third have what looks like a substantial amount of HRD, so that’s a huge biomarker,” Dr. Slavin said.
He explained that the importance of their score is that, rather than looking for the causes of HRD, they are looking for the consequences.
“We don’t know all the causes of why, all of a sudden, a tumor cell looks like it can’t replicate through homologous combination [but] what this test does is it says: ‘We don’t really care what the cause is ... we can just look at the genomic scarring and the consequences.’ ”
Elena Provenzano, MD, CRUK Therapeutic Discovery Laboratories, Cambridge (England) University Hospitals NHS Foundation Trust, who was not involved in the study, said in an interview it is “interesting work.”
“We have a personalized breast cancer program here in Cambridge and we’re running trials where we use PARP inhibitors and platinum-based therapy, and what we’re using to make these sorts of decisions is COSMIC mutational signatures associated with genetic instability. And I guess we also look at the total mutational burden,” Dr. Provenzano said.
She continued that the GIS is one of several ways of measuring HRD. “So the question is how it compares with the other measures that are being used to assess whether or not patients are suitable for PARP inhibitor and platinum-based therapy.”
Dr. Provenzano underlined that it has been known since the “early 2000s” that breast cancer is a group of different diseases. “Even within those categories there’s quite a lot of tumor types,” so it “makes sense you need to adjust the threshold slightly for it to become relevant to types of breast cancer.”
She added that the “holy grail in oncology is this concept of personalized medicine, so all these tests help us make sure that the right patient is getting the right treatment.
“At the moment TNBC is often getting treated in a similar way, although we know that there are different biological subtypes, so while there’s a significant group that falls into this BRCA-deficient group that are going to respond to PARPs there are other types that don’t.
“So these sorts of tests help us decide which subset are going to help us the most, and for the others ones we potentially need to identify other treatments as being optimal,” Dr. Provenzano said.
Previous studies have shown that HR-deficient tumors may benefit from treatment with DNA-damaging agents, and that tools such as the three-biomarker GIS can be used to identify HR deficiency.
The Food and Drug Administration has already approved a GIS threshold for identifying HR deficiency in ovarian cancer of 42, which was set as the 5th percentile for BRCA-deficient tumors. However, a recent published in Molecular Cancer Research, and a second published on MDPI Open Access Journals, indicated that a lower, first percentile, cutoff of at least 33 was associated with improved outcomes after platinum-based treatment.
As TNBC is known to have a similar molecular profile to ovarian cancer, the researchers investigated whether it has a different GIS threshold to that in ER+ breast cancer, gathering data on patients newly diagnosed with ovarian cancer, TNBC, or ER+ breast cancer from across five cohorts.
They included 127 ovarian cancer patients from Nature, 434 ovarian cancer, 44 TNBC, and 213 ER+ breast cancer patients from The Cancer Genome Atlas, 55 TNBC and 112 ER+ breast cancer patients from Breast Cancer Research, 19 TNBC and 25 ER+ breast cancer patients from TBCRC 008, and 56 ER+ breast cancer patients from OlympiAD.
GIS was defined as a combination of loss of heterozygosity, telomeric-allellic imbalance, and large-scale state transitions, identified through next-generation sequencing, and GIS distributions were compared between cancer types and subtypes.
The team also determined the presence of BRCA deficiency, finding that, among BRCA deficient tumors, the GIS distribution among patients with ER+ breast cancer was significantly different from that seen in both ovarian cancer (P = 9.6 x 10–5) and TNBC (P = 2.1 x 10–4).
The first percentile of a normal distribution of BRCA-deficient ER+ breast cancers indicated a GIS threshold of 24, with 45.1% of all ER+ tumors at or above this threshold found to be GIS positive. This translated into 98.7% of BRCA-deficient tumors and 32.7% that were BRCA intact.
The results also showed, however, that the GIS distribution for TNBC was not significantly different from that seen in ovarian cancer (P = .72), with the threshold of at least 33 Identifying 64.4% of TNBC tumors as GIS positive. This equated to 100% of BRCA-deficient tumors and 41.7% that were BRCA intact.

He explained that the importance of their score is that, rather than looking for the causes of HRD, they are looking for the consequences.
“We don’t know all the causes of why, all of a sudden, a tumor cell looks like it can’t replicate through homologous combination [but] what this test does is it says: ‘We don’t really care what the cause is ... we can just look at the genomic scarring and the consequences.’ ”
Elena Provenzano, MD, CRUK Therapeutic Discovery Laboratories, Cambridge (England) University Hospitals NHS Foundation Trust, who was not involved in the study, said in an interview it is “interesting work.”
“We have a personalized breast cancer program here in Cambridge and we’re running trials where we use PARP inhibitors and platinum-based therapy, and what we’re using to make these sorts of decisions is COSMIC mutational signatures associated with genetic instability. And I guess we also look at the total mutational burden,” Dr. Provenzano said.
She continued that the GIS is one of several ways of measuring HRD. “So the question is how it compares with the other measures that are being used to assess whether or not patients are suitable for PARP inhibitor and platinum-based therapy.”
Dr. Provenzano underlined that it has been known since the “early 2000s” that breast cancer is a group of different diseases. “Even within those categories there’s quite a lot of tumor types,” so it “makes sense you need to adjust the threshold slightly for it to become relevant to types of breast cancer.”
She added that the “holy grail in oncology is this concept of personalized medicine, so all these tests help us make sure that the right patient is getting the right treatment.
“At the moment TNBC is often getting treated in a similar way, although we know that there are different biological subtypes, so while there’s a significant group that falls into this BRCA-deficient group that are going to respond to PARPs there are other types that don’t.
“So these sorts of tests help us decide which subset are going to help us the most, and for the others ones we potentially need to identify other treatments as being optimal,” Dr. Provenzano said.
Previous studies have shown that HR-deficient tumors may benefit from treatment with DNA-damaging agents, and that tools such as the three-biomarker GIS can be used to identify HR deficiency.
The Food and Drug Administration has already approved a GIS threshold for identifying HR deficiency in ovarian cancer of 42, which was set as the 5th percentile for BRCA-deficient tumors. However, a recent published in Molecular Cancer Research, and a second published on MDPI Open Access Journals, indicated that a lower, first percentile, cutoff of at least 33 was associated with improved outcomes after platinum-based treatment.
As TNBC is known to have a similar molecular profile to ovarian cancer, the researchers investigated whether it has a different GIS threshold to that in ER+ breast cancer, gathering data on patients newly diagnosed with ovarian cancer, TNBC, or ER+ breast cancer from across five cohorts.
They included 127 ovarian cancer patients from Nature, 434 ovarian cancer, 44 TNBC, and 213 ER+ breast cancer patients from The Cancer Genome Atlas, 55 TNBC and 112 ER+ breast cancer patients from Breast Cancer Research, 19 TNBC and 25 ER+ breast cancer patients from TBCRC 008, and 56 ER+ breast cancer patients from OlympiAD.
GIS was defined as a combination of loss of heterozygosity, telomeric-allellic imbalance, and large-scale state transitions, identified through next-generation sequencing, and GIS distributions were compared between cancer types and subtypes.
The team also determined the presence of BRCA deficiency, finding that, among BRCA deficient tumors, the GIS distribution among patients with ER+ breast cancer was significantly different from that seen in both ovarian cancer (P = 9.6 x 10–5) and TNBC (P = 2.1 x 10–4).
The first percentile of a normal distribution of BRCA-deficient ER+ breast cancers indicated a GIS threshold of 24, with 45.1% of all ER+ tumors at or above this threshold found to be GIS positive. This translated into 98.7% of BRCA-deficient tumors and 32.7% that were BRCA intact.
The results also showed, however, that the GIS distribution for TNBC was not significantly different from that seen in ovarian cancer (P = .72), with the threshold of at least 33 Identifying 64.4% of TNBC tumors as GIS positive. This equated to 100% of BRCA-deficient tumors and 41.7% that were BRCA intact.

Does vitamin D benefit only those who are deficient?
, suggests a new large-scale analysis.
Data on more than 380,000 participants gathered from 35 studies showed that, overall, there is no significant relationship between 25(OH)D concentrations, a clinical indicator of vitamin D status, and the incidence of coronary heart disease (CHD), stroke, or all-cause death, in a Mendelian randomization analysis.
However, Stephen Burgess, PhD, and colleagues showed that, in vitamin D–deficient individuals, each 10 nmol/L increase in 25(OH)D concentrations reduced the risk of all-cause mortality by 31%.
The research, published in The Lancet Diabetes & Endocrinology, also suggests there was a nonsignificant link between 25(OH)D concentrations and stroke and CHD, but again, only in vitamin D deficient individuals.
In an accompanying editorial, Guillaume Butler-Laporte, MD, and J. Brent Richards, MD, praise the researchers on their study methodology.
They add that the results “could have important public health and clinical consequences” and will “allow clinicians to better weigh the potential benefits of supplementation against its risk,” such as financial cost, “for better patient care – particularly among those with frank vitamin D deficiency.”
They continue: “Given that vitamin D deficiency is relatively common and vitamin D supplementation is safe, the rationale exists to test the effect of vitamin D supplementation in those with deficiency in large-scale randomized controlled trials.”
However, Dr. Butler-Laporte and Dr. Richards, of the Lady Davis Institute, Jewish General Hospital, Montreal, also note the study has several limitations, including the fact that the lifetime exposure to lower vitamin D levels captured by Mendelian randomization may result in larger effect sizes than in conventional trials.
Prior RCTS underpowered to detect effects of vitamin D supplements
“There are several potential mechanisms by which vitamin D could be protective for cardiovascular mortality, including mechanisms linking low vitamin D status with hyperparathyroidism and low serum calcium and phosphate,” write Dr. Burgess of the MRC Biostatistics Unit, University of Cambridge (England), and coauthors.
They also highlight that vitamin D is “further implicated in endothelial cell function” and affects the transcription of genes linked to cell division and apoptosis, providing “potential mechanisms implicating vitamin D for cancer.”
The researchers note that, while epidemiologic studies have “consistently” found a link between 25(OH)D levels and increased risk of cardiovascular disease, all-cause mortality, and other chronic diseases, several large trials of vitamin D supplementation have reported “null results.”
They argue, however, that many of these trials have recruited individuals “irrespective of baseline 25(OH)D concentration” and have been underpowered to detect the effects of supplementation.
To overcome these limitations, the team gathered data from the UK Biobank, the European Prospective Investigation Into Cancer and Nutrition Cardiovascular Disease (EPIC-CVD) study, 31 studies from the Vitamin D Studies Collaboration (VitDSC), and two Copenhagen population-based studies.
They first performed an observational study that included 384,721 individuals from the UK Biobank and 26,336 from EPIC-CVD who had a valid 25(OH)D measurement and no previously known cardiovascular disease at baseline.
Researchers also included 67,992 participants from the VitDSC studies who did not have previously known cardiovascular disease. They analyzed 25(OH)D concentrations, conventional cardiovascular risk factors, and major incident cardiovascular morbidity and mortality using individual participant data.
The results showed that, at low 25(OH)D concentrations, there was an inverse association between 25(OH)D and incident CHD, stroke, and all-cause mortality.
Next, the team conducted a Mendelian randomization analysis on 333,002 individuals from the UK Biobank and 26,336 from EPIC-CVD who were of European ancestry and had both a valid 25(OH)D measurement and genetic data that passed quality-control steps.
Information on 31,362 participants in the Copenhagen population-based studies was also included, giving a total of 386,406 individuals, of whom 33,546 had CHD, 18,166 had a stroke, and 27,885 died.
The mean age of participants ranged from 54.8 to 57.5 years, and between 53.4% and 55.4% were female.
Up to 7% of study participants were vitamin D deficient
The 25(OH)D analysis indicated that 3.9% of UK Biobank and 3.7% of Copenhagen study participants were deficient, compared with 6.9% in EPIC-CVD.
Across the full range of 25(OH)D concentrations, there was no significant association between genetically predicted 25(OH)D levels and CHD, stroke, or all-cause mortality.
However, restricting the analysis to individuals deemed vitamin D deficient (25[OH]D concentration < 25 nmol/L) revealed there was “strong evidence” for an inverse association with all-cause mortality, at an odds ratio per 10 nmol/L increase in genetically predicted 25(OH)D concentration of 0.69 (P < .0001), the team notes.
There were also nonsignificant associations between being in the deficient stratum and CHD, at an odds ratio of 0.89 (P = .14), and stroke, at an odds ratio of 0.85 (P = .09).
Further analysis suggests the association between 25(OH)D concentrations and all-cause mortality has a “clear threshold shape,” the researchers say, with evidence of an inverse association at concentrations below 40 nmol/L and null associations above that threshold.
They acknowledge, however, that their study has several potential limitations, including the assumption in their Mendelian randomization that the “only causal pathway from the genetic variants to the outcome is via 25(OH)D concentrations.”
Moreover, the genetic variants may affect 25(OH)D concentrations in a different way from “dietary supplementation or other clinical interventions.”
They also concede that their study was limited to middle-aged participants of European ancestries, which means the findings “might not be applicable to other populations.”
The study was funded by the British Heart Foundation, Medical Research Council, National Institute for Health Research, Health Data Research UK, Cancer Research UK, and International Agency for Research on Cancer. Dr. Burgess has reported no relevant financial relationships. Disclosures for the other authors are listed with the article.

Surgery offers best chance in cancer but needs more ‘support’
warns a European expert.
In addition, there are many obstacles to the delivery of optimal cancer surgery, says Domenico M. D’Ugo, MD, professor of surgery at the Catholic University of Rome – A. Gemelli Medical School, Rome, Italy.
Dr. D’Ugo, who is president of the European Society of Surgical Oncology (ESSO), calls for a range of measures to improve the quality of cancer surgery and patient access in Europe.
These measures include recognition of surgical oncology as a specialist discipline, greater support for surgical research and innovation, and a greater role for surgery in multidisciplinary care.
The demands were made in open letter that was published by ESSO on Nov. 9 to coincide with the society’s annual meeting, held in Lisbon, Portugal.
The theme of this year’s meeting was the future of cancer surgery in Europe – a future that “holds many promises to make surgical oncology safer, more efficient and minimally invasive,” writes Dr. D’Ugo.
However, ESSO needs the support of European leaders to bring the recommendations to life and, ultimately, to help provide high-quality cancer treatment, he adds. This is particularly important given the upcoming implementation of Europe’s Beating Cancer Plan.
The open letter is addressed to Stella Kyriakides, European commissioner for health and food safety, and Bartosz Arłukowicz, chair of the European Parliament Special Committee on Beating Cancer, among others.
Best chance of cure
“High-quality surgery remains the best chance to cure solid cancer when diagnosed early,” Dr. D’Ugo notes in his letter. It is also the most cost-effective treatment for the majority of nonmetastasized tumors, he writes.
In addition, surgery is “fundamental” to the prevention of cancer in patients with inherited susceptibility and to the diagnosis and staging of cancer, as well as to the treatment of metastatic disease, the preservation of quality of life, and the alleviation of cancer symptoms, he writes.
There is thus a substantial and steadily growing demand for surgical oncology.
It is estimated that approximately 80% of cancer patients will require surgical intervention at some point during the course of their disease, and 45 million surgical procedures will be needed worldwide by 2030.
Dr. D’Ugo says that at present, fewer than a quarter of cancer patients receive safe, affordable, or timely surgery.
It is time to give surgical oncology the political and financial attention it deserves, he argues. He outlines a four-point plan to achieve this.
The first point is to enhance recognition of surgical oncology as a specialist discipline through, for example, the global curriculum proposed by ESSO and the Society of Surgical Oncology in 2016.
At present, only eight countries in Europe recognize surgical oncology as a specialty, and the lack of harmonization is “causing disparities in training, qualifications and practices,” as well as in patient access, Dr. D’Ugo says.
Next is a call to support research and innovation. Despite recent advances, research in cancer surgery “remains highly underfunded in Europe when compared with pharmaceutical research,” he says.
Improved screening and early detection of cancer are the next key area, because when the disease is diagnosed at an early stage, curative surgery has “a greater chance to be successful.”
At present, screening programs in Europe address only colorectal, breast, and cervical cancers, and the uptake remains “low,” he writes.
Lastly, he emphasizes that surgery is “integral” to multidisciplinary care and that outcomes for patients are better in comprehensive cancer centers that support patients throughout the disease pathway.
Dr. D’Ugo suggests that surgical oncologists take on a “bigger role” in multidisciplinary care, and he calls for the certification and accreditation of cancer units to increase and unify standards of care across the region.
D’Ugo has disclosed no relevant financial relationships.

Antiepileptic medications linked to increased priapism risk
Several antiepileptic drugs (AEDs) are associated with an increased risk for priapism, new research suggests.
After analyzing U.S. adverse event reporting data, investigators found that among nearly 200 cases of priapism, a persistent, often painful erection unrelated to sexual interest or stimulation that lasts more than 4 hours, eight AEDs were associated with a positive “safety signal” for priapism.
These included valpromide, brivaracetam, valproic acid, topiramate, oxcarbazepine, clonazepam, levetiracetam, and carbamazepine. Of these, valpromide had the largest association.
“Based on our results, we would recommend to clinicians to be cautious about the possibility of encountering priapism” in patients receiving the eight AEDs identified, lead researcher Ana Pejcic, PhD, department of pharmacology and toxicology, University of Kragujevac, Serbia, told meeting attendees.
If clinicians encounter such cases, they should be “reported to the regulatory authorities,” Dr. Pejcic added.
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
Noteworthy limitations
Dr. Pejcic told this news organization that the safety signal with AEDs “does not directly mean that a medicine has caused the reported adverse event” because an illness or other drug taken by the patient could be responsible instead.
She also noted that the U.S. Food and Drug Administration’s Adverse Event Reporting System relies on “spontaneous reports of adverse events,” which have multiple limitations.
These limitations include that the FDA “does not require that a causal relationship between a drug and event be proven, and reports do not always have enough information to properly evaluate an event.”
Nevertheless, Dr. Pejcic added that if a causal relationship was to be shown, the underlying mechanism could be linked to the pharmacological properties of the individual antiepileptic, such as altered alpha-1 adrenergic receptor expression or increased dopamine release.
Still, that would require “further evaluation in larger pharmacoepidemiological studies, with adjustment for potential confounding variables,” she said.
Replication needed
Priapism has recently been observed in case reports in association with the use of some AEDs. In addition, use of the drugs has been associated with hypo- and hypersexuality, as well as erectile and ejaculatory dysfunction.
Because the relationship between priapism and AED use “has not been well characterized,” the researchers mined data from the FDA’s Adverse Event Reporting System.
They examined entries from the first quarter of 2004 and the third quarter of 2020, focusing on 47 AEDs from the N03A subgroup of the Anatomical Therapeutic Chemical Classification System.
The researchers identified 8,122,037 cases for data analysis, of which 1,936 involved priapism as an adverse event. In total, 16 antiepileptic medications had at least one case of an adverse event involving priapism.
A positive safety signal was defined as a Proportional Reporting Ratio (PRR) of at least two, a chi-squared of at least four, or three or more cases. The signal was detected for valpromide, brivaracetam, valproic acid, topiramate, oxcarbazepine, clonazepam, levetiracetam, and carbamazepine.
The largest association with priapism was with valpromide, at a PRR of 61.79. That was followed by PRR of 9.61 for brivaracetam, 7.28 for valproic acid, and 3.23 for topiramate.
“Considering that the proportionality analysis we applied in our study is used for hypothesis generation, our results will need to confirm in large cohorts and case-control studies,” said Dr. Pejcic.
New and important hypothesis?
Commenting on the study, Daniel Goldenholz, MD, PhD, instructor in the Division of Epilepsy, Beth Israel Deaconess Medical Center, Boston, said priapism is not something that practicing epileptologists are instructed “to look for.”
He noted that “the idea of looking for a hidden signal in a massive database like this is very appealing” because it could reveal patterns that were previously undetected.
However, the event rate in the study suggests priapism, which “in the right context would be considered a medical emergency, [is] relatively uncommon,” said Dr. Goldenholz, who was not involved with the research.
He noted that medications that could cause priapism, “such as antidepressants, blood pressure meds, and anticoagulants,” are commonly used by many people – including those with epilepsy.
It is consequently possible that “the finding from this study can be explained by comorbid medical problems,” Dr. Goldenholz said. This is particularly likely because many of the AEDs in question “have been on the market for decades,” he added.
“If a seemingly dangerous symptom would be happening as a result of one of these medications, ,” he said.
Still, Dr. Goldenholz noted that it is “possible that these authors have a new and important hypothesis which must now be tested: Does priapism occur in patients with antiseizure medications when other causes are already ruled out?”
The investigators and Dr. Goldenholz have disclosed no relevant financial relationships.

Art therapy linked to slowed Parkinson’s progression
Adding art therapy to standard drug treatment in Parkinson’s disease (PD) not only improves severity of both motor and nonmotor symptoms, but also slows rates of disease progression, new research suggests.
Fifty PD patients were randomly assigned to receive either art therapy, including sculpting and drawing, plus drug therapy or drug therapy alone, and followed up over 12 months.
Patients receiving combined therapy experienced improvements in symptoms, depression, and cognitive scores, and had reduced tremor and daytime sleepiness. They were also substantially less likely to experience disease progression.
“The use of art therapy can reduce the severity of motor and nonmotor manifestations of Parkinson’s disease,” said study investigator Iryna Khubetova, MD, PhD, head of the neurology department, Odessa (Ukraine) Regional Clinical Hospital.
she added.
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
A promising approach
Dr. Khubetova told this news organization that offering art therapy to PD patients was “very affordable,” especially as professional artists “provided materials for painting and other art supplies free of charge.”
“We hope this approach is very promising and would be widely adopted.”
She suggested the positive effect of art therapy could be related to “activating the brain’s reward neural network.”
This may be via improved visual attention acting on visuospatial mechanisms and emotional drive, with “activation of the medial orbitofrontal cortex, ventral striatum, and other structures.”
The researchers note PD, a “multisystem progressive neurodegenerative disease,” is among the three most common neurological disorders, with an incidence of 100-150 cases per 100,000 people.
They also note that nonpharmacologic approaches are “widely used” as an adjunct to drug therapy and as part of an “integrated approach” to disease management.
To examine the clinical efficacy of art therapy, the team recruited patients with PD who had preserved facility for independent movement, defined as stages 1-2.5 on the Hoehn and Yahr scale.
Patients were randomly assigned to art therapy sessions alongside standard drug therapy or to standard drug therapy alone. The art therapy included sculpting, free drawing, and coloring patterns.
Multiple benefits
Participants were assessed at baseline and at 6 and 12 months with the Unified Parkinson Disease Rating Scale (UPDRS), the Beck Depression Inventory, the Montreal Cognitive Assessment, and the Pegboard Test of finger dexterity.
Fifty patients were included in the study, with 30 assigned to standard drug therapy alone and 20 to the combined intervention. Participants had a mean age of 57.8 years, and 46% were women.
Over the study period, investigators found patients assigned to art therapy plus drug treatment had improved mood, as well as decreased daytime sleeping, reduced tremor, and a decrease in anxiety and fear intensity.
Between baseline and the 6- and 12-month assessments, patients in the combined therapy group showed improvements in scores on all of the questionnaires, and on the Pegboard Test. In contrast, scores were either stable or worsened in the standard drug therapy–alone group.
The team notes that there was also a marked difference in rates of disease progression, defined as a change on the Hoehn and Yahr scale of at least 0.5 points, between the two groups.
Only two (10%) patients in the combined drug and art therapy progressed over the study period, compared with 10 (33%) in the control group (P = .05).
The findings complement those of a recent study conducted by Alberto Cucca, MD, of the Fresco Institute for Parkinson’s and Movement Disorders, New York University, and colleagues.
Eighteen patients took part in the prospective, open-label trial. They were assessed before and after 20 sessions of art therapy on a range of measures.
Results revealed that following the art therapy, patients had improvements in the Navon Test (which assesses visual neglect, eye tracking, and UPDRS scores), as well as significantly increased functional connectivity levels in the visual cortex on resting-state functional MRI.
Many benefits, no side effects
Rebecca Gilbert, MD, PhD, vice president and chief scientific officer of the American Parkinson Disease Association, who was not involved in either study, told this news organization that the idea of art therapy for patients with Parkinson’s is “very reasonable.”
She highlighted that “people with Parkinson’s have many issues with their visuospatial abilities,” as well as their depth and distance perception, and so “enhancing that aspect could potentially be very beneficial.”
“So I’m hopeful that it’s a really good avenue to explore, and the preliminary data are very exciting.”
Dr. Gilbert also highlighted that the “wonderful” aspect of art therapy is that there are “so many benefits and not really any side effects.” Patients can “take the meds … and then enhance that with various therapies, and this would be an additional option.”
Another notable aspect of art therapy is the “social element” and the sense of “camaraderie,” although that has “to be teased out from the benefits you would get from the actual art therapy.”
Finally, Dr. Gilbert pointed out that the difference between the current trial and Dr. Cucca’s trial is the presence of a control group.
“Of course, it’s not blinded, because you know whether you got therapy or not … but that extra element of being able to compare with a group that didn’t get the treatment gives it a little more weight in terms of the field.”
No funding was declared. The authors have disclosed no relevant financial relationships.

‘Impressive’ results for novel antidepressant, so why the FDA delay?
A novel antidepressant (AXS-05, Axsome Therapeutics) appears to have a rapid and durable effect in patients with major depressive disorder (MDD), results of an open label, phase 3 trial, show. Yet, its new drug application (NDA) remains in limbo with the U.S. Food and Drug Administration for reasons that are unclear.
In the study, which included 876 patients with MDD, results showed the drug, a combination of dextromethorphan and bupropion, had a clinical response rate of 80% and a remission rate of almost 70%. In addition, functional improvements were “substantial” and AXS-05 was determined to be “generally safe and well-tolerated.”
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
The study
The COMET trial was a phase 3, multicenter, U.S. trial, in which patients with MDD were treated with AXS-05 twice daily for up to 12 months. Patients had to have a Montgomery-Åsberg Depression Rating Scale (MADRS) score of at least 25. They could have completed a prior AXS-05 study or be newly enrolled.
Of 876 patients included in the study, 611 were newly enrolled. The mean age was 42.4 years, and 62.4% were women. Just over half (58.1%) were White, with 35.6% Black, and 2.0% Asian. The mean body mass index was 31.4 kg/m2.
The mean MADRS total score at baseline was 32.7 and the Sheehan Disability Scale (SDS) score was 20.0.
Presenting efficacy data in 609 newly enrolled patients, the team showed that MADRS total scores fell sharply on starting AXS-05, by 9.1 points at week 1, 14.0 points at week 2, and 21.2 points at week 6.
By 6 months, the reduction over baseline was 23.9 points, which was maintained out to 12 months, at a mean reduction of 23.0 points.
The proportion of patients achieving a clinical response, defined as a greater than or equal to 50% improvement in MADRS scores, was 18.8% at week 1, 39.7% at week 2, and 73.2% at week 6. There was a clinical response in 84.6% of patients at 6 months and in 82.8% at 12 months.
Clinical remission, defined as a MADRS score less than or equal to 10, was achieved in 8.3% of patients at week 1, rising to 21.5% at week 2, and 52.5% at week 6. At 6 months, 68.7% of patients were in clinical remission, reaching 69.0% at 12 months.
These benefits were accompanied by substantial improvements in depressive symptoms on the Clinical Global Impression of Improvement scale, with a marked or moderate improvement seen in 86.7% of patients at 6 months and 93.1% at 12 months.
Moreover, a clinical response in functioning on the SDS was achieved by 80.6% of patients at 6 months and 75.9% at 12 months.
The safety analysis of AXS-05 in the entire cohort suggested it was well-tolerated, with dizziness seen in 12.7% of patients, along with nausea in 11.9%, headache in 8.8%, dry mouth in 7.1%, and decreased appetite in 6.1%.
The rate of discontinuation due to adverse events was 8.4%, and there were no signs of psychotomimetic effects, cognitive impairment, weight gain, or increased sexual dysfunction.
and increased rates of suicidal ideation resolution, and was also effective for treatment-resistant depression.
Results from an analysis of the ASCEND phase 2 and GEMINI phase 3 trials also suggested that AXS-05 was superior to both bupropion and placebo in achieving rapid and sustained improvements in depression symptoms.
FDA delay
Yet despite these seemingly positive findings, the FDA appears to have issues with the agent’s new drug application.
As reported in August, the agency reviewed the NDA for AXS-05 for the treatment of MDD, but at that time the drug’s manufacturer revealed that the agency had identified “deficiencies that preclude labeling discussions at this time.”
With the latest results presented at ECNP 2021, this news organization asked Axsome about the status of the NDA and whether there had been any further discussions and/or movement with the FDA.
Instead of a direct reply from the drug company, this news organization was directed to a statement released by Axsome in August announcing that the FDA had informed the company that its NDA review “would not be completed by the Prescription Drug User Fee Act target action date of August 22, 2021.”
“The FDA did not request additional information from the company, and the review of the application is ongoing,” the statement said. Axsome did not respond to further questions.
‘Impressive’ remission rate
Commenting on the research, Marin Jukic, PhD, department of physiology and pharmacology, Karolinska Institutet, Stockholm, who was not involved in the research, said AXS-05 “looks promising in relation to the efficacy and tolerability results” with a remission rate that is “truly impressive.”
However, Dr. Jukic cautioned that it was an open-label trial and therefore had no placebo or active comparator arms.
He noted that it would be “interesting to compare the efficacy with placebo and escitalopram, for example, to evaluate the potential for the benefits and efficacy better.”
The research was funded by Axsome Therapeutics, and, except for one, the researchers for the four studies are employees of Axsome Therapeutics.

A novel antidepressant (AXS-05, Axsome Therapeutics) appears to have a rapid and durable effect in patients with major depressive disorder (MDD), results of an open label, phase 3 trial, show. Yet, its new drug application (NDA) remains in limbo with the U.S. Food and Drug Administration for reasons that are unclear.
In the study, which included 876 patients with MDD, results showed the drug, a combination of dextromethorphan and bupropion, had a clinical response rate of 80% and a remission rate of almost 70%. In addition, functional improvements were “substantial” and AXS-05 was determined to be “generally safe and well-tolerated.”
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
The study
The COMET trial was a phase 3, multicenter, U.S. trial, in which patients with MDD were treated with AXS-05 twice daily for up to 12 months. Patients had to have a Montgomery-Åsberg Depression Rating Scale (MADRS) score of at least 25. They could have completed a prior AXS-05 study or be newly enrolled.
Of 876 patients included in the study, 611 were newly enrolled. The mean age was 42.4 years, and 62.4% were women. Just over half (58.1%) were White, with 35.6% Black, and 2.0% Asian. The mean body mass index was 31.4 kg/m2.
The mean MADRS total score at baseline was 32.7 and the Sheehan Disability Scale (SDS) score was 20.0.
Presenting efficacy data in 609 newly enrolled patients, the team showed that MADRS total scores fell sharply on starting AXS-05, by 9.1 points at week 1, 14.0 points at week 2, and 21.2 points at week 6.
By 6 months, the reduction over baseline was 23.9 points, which was maintained out to 12 months, at a mean reduction of 23.0 points.
The proportion of patients achieving a clinical response, defined as a greater than or equal to 50% improvement in MADRS scores, was 18.8% at week 1, 39.7% at week 2, and 73.2% at week 6. There was a clinical response in 84.6% of patients at 6 months and in 82.8% at 12 months.
Clinical remission, defined as a MADRS score less than or equal to 10, was achieved in 8.3% of patients at week 1, rising to 21.5% at week 2, and 52.5% at week 6. At 6 months, 68.7% of patients were in clinical remission, reaching 69.0% at 12 months.

Lower thyroid hormone levels a red flag for elevated suicide risk?
Patients with comorbid anxiety and mood disorders who have reduced, albeit “normal” serum levels of thyroid-stimulating hormone (TSH) may be at increased risk for suicidal ideation, new research suggests.
In a cross-sectional study, clinical data on diagnosis, medication use, and symptom scores were gathered, along with assessments of blood levels of thyroid axis hormones, in patients with both anxiety and mood disorders.
After investigators accounted for age, gender, symptoms, medication use, and other potential confounders, patients with suicidal ideation were 54% less likely to have higher TSH levels. There was no association found with other thyroid hormones.
Based on the results, the assessment of thyroid hormone levels “may be important for suicide prevention and might allow clinicians to evaluate the potential of the suicidal ideation risk in individuals with [anxiety and mood disorders],” co-investigator Vilma Liaugaudaite, PhD student, Neuroscience Institute of the Lithuanian University of Health Sciences, Palanga, and colleagues note.
The findings were presented at the 34th European College of Neuropsychopharmacology (ECNP) Congress.
‘Complex mechanism’
Ms. Liaugaudaite told this news organization that thyroid hormones are known to have a “profound” effect on mood and behavior.
Recent studies show “various degrees of hypothalamic-pituitary-thyroid axis dysregulation are associated with suicidal behavior” in patients with depression, she added.
Noting that disturbances in the serotonin system “constitute the most common biochemical abnormality associated with suicidal behavior,” Ms. Liaugaudaite said it is thought thyroid hormones “are involved in a complex compensatory mechanism to correct reduced central 5-hydroxytryptamine activity” via lower TSH levels.
In addition, hypersecretion of thyrotropin-releasing hormone, which stimulates the release of TSH, “has been considered a compensatory mechanism to maintain normal thyroid hormone secretion and normalize serotonin activity in depressed patients,” she said.
To investigate associations between thyroid axis hormones and suicidality in individuals with comorbid anxiety and mood disorders, the researchers assessed consecutive patients attending a stress disorders clinic.
Sociodemographic and clinical information was gathered, and patients completed the Mini International Neuropsychiatric Interview, the Patient Health Questionnaire-9 (PHQ-9), and the General Anxiety Disorder-7 (GAD-7) scale.
Fasting blood samples were also tested for free thyroxine (FT4), free triiodothyronine (FT3), and TSH levels.
Significant association
Suicidal ideation was identified in 42 participants. Serum FT4, FT3, and TSH levels were within the normal range.
There were no significant differences between patients with and without suicidal ideation in terms of age, gender, education, obesity, smoking, and medication use.
Suicidal ideation was associated with higher scores on the PHQ-9 (15.5 vs. 13.3; P = .085), and with lower TSH levels (1.54 IU/L vs. 2.04 IU/L; P = .092).
The association between serum TSH levels and suicidal ideation was significant after multivariate logistic regression analysis accounted for age, gender, PHQ-9 and GAD-7 scores, education, body mass index, smoking, and use of antidepressants, tranquilizers, mood stabilizers, and neuroleptics.
Specifically, patients with suicidal ideation were significantly less likely to have higher TSH levels than those without, at an odds ratio of 0.46 (P = .027).
There were no significant associations between serum FT4 and FT3 levels and suicidal ideation.
Interesting, but preliminary
Commenting on the findings, Sanjeev Sockalingam, MD, vice chair and professor of psychiatry at the University of Toronto, said it is an “interesting study” because the literature on trying to identify individuals at risk for suicidal ideation or behaviors is “quite mixed, in terms of the results.”
However, it was a cross-sectional study with a relatively small sample size, and studies of this nature typically include patients with hypothyroidism “who end up having suicidal thoughts,” said Dr. Sockalingam, who was not involved with the research.
“I do wonder, given the sample size and patient population, if there may be other factors that may have been related to this,” he added.
Dr. Sockalingam noted that he would like to see more data on the medications the patients were taking, and he underlined that the thyroid levels were in the normal range, “so it’s a bit difficult to untangle what that means in terms of these subtle changes in thyroid levels.”
Robert Levitan, MD, Cameron Wilson Chair in Depression Research at the Centre for Addiction and Mental Health, Toronto, also emphasized that the thyroid levels were in the normal range.
He commented that it therefore “seems unlikely that there’s going to be some biological effect that’s going to affect the brain in a significant enough way” to influence suicidal ideation.
Dr. Levitan continued, “What’s probably happening is there’s some other clinical issue here that they just haven’t picked up on that’s leading in one direction to the suicidal ideation and perhaps affecting the TSH to some extent.”
Although the study is, therefore, “preliminary,” the findings are nevertheless “interesting,” he concluded.
The study received no funding. Ms. Liaugaudaite, Dr. Sockalingam, and Dr. Levitan have disclosed no relevant financial relationships.

Steroid a promising short-term treatment option for major depression?
Study results of an experimental agent that improves symptoms of major depression and boosts quality of life in as little as 3 days suggest it may be an effective short-term treatment option.
Phase 3 results of a randomized, placebo-controlled trial compared zuranolone, an neuroactive steroid that binds to both synaptic and extra-synaptic GABA-A receptors, to placebo in patients with major depressive disorder (MDD). Overall, 30% of participants were already taking antidepressants.
Investigators found the drug was associated with a significant improvement in depression scores versus placebo, with benefit observed as early as day 3. This was accompanied by improved function and well-being.
, said study presenter Colville Brown, MD, Sage Therapeutics, Cambridge, Mass.
“These data continue to support the development of zuranolone as a potential 14-day short course treatment for major depressive disorder episodes.”
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
High placebo response
However, despite being significant, the drug’s benefit was only slightly higher than that of placebo, raising questions about the study design and the true performance of the drug.
Dr. Brown explained that patients with MDD were randomized to oral zuranolone 50 mg or placebo once daily for 14 days, with dose reductions to 40 mg or matching placebo permitted in case of perceived intolerance.
Patients were assessed at baseline and day 15 via the 17-item Hamilton Rating Scale for Depression (HAMD-17) before entering a 28-day follow-up period off the study drug.
Among the 268 participants who received zuranolone, 90.3% completed the study, compared with 87.4% of 269 patients in the placebo group.
The mean age of participants was 40 years. Women made up 69.4% of those who received zuranolone and 61.7% assigned to placebo.
The mean HAMD-17 score at baseline was 26.8 and 26.9 in the zuranolone and placebo groups, respectively. Dr. Brown noted that 29.5% of patients in the zuranolone group and 30.1% of those assigned to placebo were taking antidepressants at baseline.
The study’s primary endpoint was met, with patients taking the study drug experiencing a significantly greater reduction in HAMD-17 scores from baseline to day 15 versus those given placebo, at 14.1 versus 12.3 points (P = .0141).
Dr. Brown highlighted that the difference in reduction in HAMD-17 scores between the zuranolone and placebo groups was already significant at day 3 (P < .0001), and again at day 8 (P < .0001) and day 12 (P < .001).
At day 3, response rates on the HAMD-17 were significantly higher among zuranolone-treated patients than among those given placebo, at 29.3% versus 16.3% (P < .001). However, the differences on day 15 and on day 42 were no longer significant.
A similar effect was seen for HAMD-17 remissions, which were seen in 7.6% of zuranolone-treated patients and 2.3% of those given placebo at day 3 (P < .01), rising to 29.8% versus 27.1% at day 15, and 30.8% versus 29.6% at day 42, and neither difference was significant.
Dr. Brown also showed that, at all time points during the treatment and follow-up periods, improvements in response rates in Global Improvement on the Clinical Global Impression scale favored zuranolone.
On the SF-36v2 quality of life questionnaire, improvements again favored zuranolone on all domains, although the difference between active treatment and placebo was significant only for vitality on day 15, at 12.8 versus 9.7 points (P < .05).
Treatment-emergent adverse events were more common with zuranolone, with 60.1% of patients experiencing at least one event of any grade versus 44.6% with placebo. However, severe events were seen in only 3.0% versus 1.1% of patients, and serious adverse events were recorded in only two patients (0.7%) in both groups.
The most common adverse events were somnolence, dizziness, headache, sedation, and diarrhea, with no increase in suicidal ideation or withdrawal. Dr. Brown noted that there was “no change in the safety signal” between patients with or without prior antidepressant therapy.
From the audience, Marie-Josée Filteau, MD, department of psychiatry, Laval University, Quebec, drew attention to the similarity in the improvement in HAMD-17 scores between the zuranolone and placebo groups, asking: “How is that compelling?”
Dr. Brown replied that “what they are excited about is that change from baseline with zuranolone,” adding: “You do see it in the placebo group as well, and ... this isn’t new to psychiatry.
“This is a heterogeneous disease, and remember this [study] was conducted during COVID, so patients were being seen with clinic visits during COVID.
“What impact did that have? The placebo is not really placebo” in this case.
More effective than results suggest?
Approached for comment by this news organization, Maurizio Fava, MD, executive vice chair, department of psychiatry, and executive director, Clinical Trials Network and Institute, Massachusetts General Hospital, Boston, noted there are several issues with the trial.
Because of those, the drug “is likely to be much more efficacious than it looks because it achieved statistical significance despite an extremely high placebo response,” he said
“Whenever your change on placebo is greater than 10 points on the HAMD, you have an excessive response ... and a very, very low chance of detecting a signal,” he said.
Dr. Fava said that another issue was including patients who were either on or off antidepressants, which meant the population was not sufficiently homogenous.
Another “flaw” was to assume that the placebo effect would be “transient” and deteriorate over time, whereas the results showed the opposite.
Nevertheless, “it’s a positive study because of the sample size ... that provides further evidence for the antidepressant activity of zuranolone” and the drug was “well tolerated.”
Dr. Fava expects zuranolone “will make it to the market,” as an indication from the Food and Drug Administration is likely, “but if you’re asking me: Is the drug as effective as shown in their studies? It’s probably much more effective.”
The study was funded by Sage Therapeutics and Biogen. Dr. Brown is an employee of Sage Therapeutics.

Study results of an experimental agent that improves symptoms of major depression and boosts quality of life in as little as 3 days suggest it may be an effective short-term treatment option.
Phase 3 results of a randomized, placebo-controlled trial compared zuranolone, an neuroactive steroid that binds to both synaptic and extra-synaptic GABA-A receptors, to placebo in patients with major depressive disorder (MDD). Overall, 30% of participants were already taking antidepressants.
Investigators found the drug was associated with a significant improvement in depression scores versus placebo, with benefit observed as early as day 3. This was accompanied by improved function and well-being.
, said study presenter Colville Brown, MD, Sage Therapeutics, Cambridge, Mass.
“These data continue to support the development of zuranolone as a potential 14-day short course treatment for major depressive disorder episodes.”
The findings were presented at the virtual congress of the European College of Neuropsychopharmacology.
High placebo response
However, despite being significant, the drug’s benefit was only slightly higher than that of placebo, raising questions about the study design and the true performance of the drug.
Dr. Brown explained that patients with MDD were randomized to oral zuranolone 50 mg or placebo once daily for 14 days, with dose reductions to 40 mg or matching placebo permitted in case of perceived intolerance.
Patients were assessed at baseline and day 15 via the 17-item Hamilton Rating Scale for Depression (HAMD-17) before entering a 28-day follow-up period off the study drug.
Among the 268 participants who received zuranolone, 90.3% completed the study, compared with 87.4% of 269 patients in the placebo group.
The mean age of participants was 40 years. Women made up 69.4% of those who received zuranolone and 61.7% assigned to placebo.
The mean HAMD-17 score at baseline was 26.8 and 26.9 in the zuranolone and placebo groups, respectively. Dr. Brown noted that 29.5% of patients in the zuranolone group and 30.1% of those assigned to placebo were taking antidepressants at baseline.
The study’s primary endpoint was met, with patients taking the study drug experiencing a significantly greater reduction in HAMD-17 scores from baseline to day 15 versus those given placebo, at 14.1 versus 12.3 points (P = .0141).
Dr. Brown highlighted that the difference in reduction in HAMD-17 scores between the zuranolone and placebo groups was already significant at day 3 (P < .0001), and again at day 8 (P < .0001) and day 12 (P < .001).
At day 3, response rates on the HAMD-17 were significantly higher among zuranolone-treated patients than among those given placebo, at 29.3% versus 16.3% (P < .001). However, the differences on day 15 and on day 42 were no longer significant.
A similar effect was seen for HAMD-17 remissions, which were seen in 7.6% of zuranolone-treated patients and 2.3% of those given placebo at day 3 (P < .01), rising to 29.8% versus 27.1% at day 15, and 30.8% versus 29.6% at day 42, and neither difference was significant.
Dr. Brown also showed that, at all time points during the treatment and follow-up periods, improvements in response rates in Global Improvement on the Clinical Global Impression scale favored zuranolone.
On the SF-36v2 quality of life questionnaire, improvements again favored zuranolone on all domains, although the difference between active treatment and placebo was significant only for vitality on day 15, at 12.8 versus 9.7 points (P < .05).
Treatment-emergent adverse events were more common with zuranolone, with 60.1% of patients experiencing at least one event of any grade versus 44.6% with placebo. However, severe events were seen in only 3.0% versus 1.1% of patients, and serious adverse events were recorded in only two patients (0.7%) in both groups.
The most common adverse events were somnolence, dizziness, headache, sedation, and diarrhea, with no increase in suicidal ideation or withdrawal. Dr. Brown noted that there was “no change in the safety signal” between patients with or without prior antidepressant therapy.

Constipation med boosts cognitive performance in mental illness
, new research suggests.
In a randomized controlled trial, 44 healthy individuals were assigned to receive the selective serotonin-4 (5-HT4) receptor agonist prucalopride (Motegrity) or placebo for 1 week.
After 6 days, the active-treatment group performed significantly better on memory tests than the participants who received placebo. In addition, the drug increased activity in brain areas related to cognition.
“What we’re hoping is...these agents may be able to help those with cognitive impairment as part of their mental illness,” lead author Angharad N. de Cates, a clinical DPhil student in the department of psychiatry, University of Oxford, Oxford, United Kingdom, told meeting attendees.
“Currently, we’re looking to see if we can translate our finding a step further and do a similar study in those with depression,” Ms. de Cates added.
The findings were presented at the 34th European College of Neuropsychopharmacology (ECNP) Congress and were simultaneously published in Translational Psychiatry.
“Exciting early evidence”
“Even when the low mood associated with depression is well-treated with conventional antidepressants, many patients continue to experience problems with their memory,” co-investigator Susannah Murphy, PhD, a senior research fellow at the University of Oxford, said in a release.
“Our study provides exciting early evidence in humans of a new approach that might be a helpful way to treat these residual cognitive symptoms,” Dr. Murphy added.
Preclinical and animal studies suggest that the 5-HT4 receptor is a promising treatment target for cognitive impairment in individuals with psychiatric disorders, although studies in humans have been limited by the adverse effects of early agents.
“We’ve had our eye on this receptor for a while,” explained de Cates, inasmuch as the animal data “have been so good.”
However, she said in an interview that “a lack of safe human agents made translation tricky.”
As previously reported, prucalopride, a selective high-affinity 5-HT4 partial agonist, was approved in 2018 by the U.S. Food and Drug Administration for the treatment of chronic idiopathic constipation.
The current researchers note that the drug has “good brain penetration,” which “allowed us to investigate 5-HT4-receptor agonism in humans.”
Having previously shown that a single dose of the drug has “pro-cognitive effects,” the investigators conducted the new trial in 44 healthy participants. All were randomly assigned in a 1:1 ratio to receive either prucalopride 1 mg for 7 days or placebo.
In accordance with enrollment criteria, patients were 18 to 36 years of age, right-handed, and were not pregnant or breastfeeding. Participants’ body mass index was 18 to 30 kg/m2, and they had no contraindications to the study drug. The two treatment groups were well balanced; the participants who received placebo were significantly more likely to be nonnative English speakers (P = .02).
On day 6 of treatment administration, all participants underwent 3T MRI.
Before undergoing imaging, the participants were presented with eight emotionally neutral images of animals or landscapes and were asked to indicate whether or not the images were of animals. The task was then repeated with the eight familiar images and eight novel ones.
During the scan, participants were shown the same images or eight novel images and were again asked whether or not the images contained an animal. They were also instructed to try to remember the images for a subsequent memory task. In that task, the eight original images, 48 novel images, and 27 “distractor” images were presented.
Better memory
In the pre-scan assessment, results showed no significant differences in the ability of members of the prucalopride and placebo groups to identify images as being familiar or different.
However, taking prucalopride was associated with significantly improved memory performance in the post-scan recall task.
Compared to the placebo group, participants in the prucalopride group were more accurate in selecting images as familiar vs distractors (P = .029) and in distinguishing images as familiar, novel, or distractors (P = .035).
Functional MRI revealed increased activity in the left and right hippocampus in response to both novel and familiar images among the participants in the prucalopride group in comparison with those in the placebo group.
There was also increased activity in the right angular gyrus in the prucalopride group in comparison with the placebo group in response to familiar images (P < .005).
“Clinically, angular gyri lesions cause language dysfunction, low mood, and poor memory and can mimic dementia or pseudodementia,” the investigators write. They note that the right angular gyrus “shows significantly decreased activity” in mild cognitive impairment.
“Therefore, the increased activity seen in the right angular gyrus following prucalopride administration in our study is consistent with the pro-cognitive behavioural effects we observed,” they add.
Ms. De Cates noted that the dose used in their study was lower than the 2 mg given for constipation.
“At the low dose, there were no differences in side effects between groups and no withdrawals from the prucalopride group for side effects. We are going to try increasing the dose in our next study actually, as we don’t have PET data to tell us what the optimal dose for binding at the receptor should be,” said Ms. de Cates.
“In safety studies, the dose was trialled in healthy volunteers at 4 mg, which was found to be safe, although perhaps less well tolerated than 2 mg,” she said.
Generalizable findings?
Commenting on the research, Vibe G. Frøkjær, MD, adjunct professor, department of psychology, Copenhagen University, Denmark, said the study “highlights a very interesting and much needed potential for repurposing drugs to help cognitive dysfunction.”
He noted that cognitive dysfunction is often associated with psychiatric disorders -- even in states of remission.
“Importantly, as the authors also state, it will be vital to translate these findings from healthy populations into clinical populations,” said Dr. Frøkjær, who was not involved in the research.
“It will also be important to understand if prucalopride adds to the effects of existing antidepressant treatments or can be used as a stand-alone therapy,” he added.
The study was funded by the NIHR Oxford Health Biomedical Research Center and by the Wellcome Center for Integrative Neuroscience. Ms. De Cates has received a travel grant from the Royal College of Psychiatrists/Gatsby Foundation and support from Wellcome. The other authors have relationships with P1vital Ltd, Janssen Pharmaceuticals, Sage Therapeutics, Pfizer, Zogenix, Compass Pathways, and Lundbeck.

He noted that cognitive dysfunction is often associated with psychiatric disorders -- even in states of remission.
“Importantly, as the authors also state, it will be vital to translate these findings from healthy populations into clinical populations,” said Dr. Frøkjær, who was not involved in the research.
“It will also be important to understand if prucalopride adds to the effects of existing antidepressant treatments or can be used as a stand-alone therapy,” he added.
The study was funded by the NIHR Oxford Health Biomedical Research Center and by the Wellcome Center for Integrative Neuroscience. Ms. De Cates has received a travel grant from the Royal College of Psychiatrists/Gatsby Foundation and support from Wellcome. The other authors have relationships with P1vital Ltd, Janssen Pharmaceuticals, Sage Therapeutics, Pfizer, Zogenix, Compass Pathways, and Lundbeck.
