New CFTR [cystic fibrosis transmembrane conductance regulator] modulator therapies can offer life-altering benefits to some patients with cystic fibrosis, even those with advanced disease.

Triple combination therapy in cystic fibrosis patients with advanced lung disease appears to improve lung function, and may delay the need for lung transplantation, according to a multicenter analysis of patients taking elexacaftor, tezacaftor, and ivacaftor.

The study participants had a percent predicted forced expiratory volume in 1 second (ppFEV₁) of 40% or below, or other high-risk factors. Researchers compared them to control patients who were genetically ineligible for triple combination therapy.

Previous studies of such patients on individual drugs or previous combinations showed increases in lung function in patients with advanced disease, though the magnitude of improvement varied across regimens. “With this improvement, it’s unclear how CFTR modulators should affect lung transplant referral timing,” Brent Bermingham, MD, said during a presentation of the study at the virtual North American Cystic Fibrosis Conference.

“The rationale for our study was that despite patients with advanced lung disease being excluded from phase III trials (of elexacaftor, tezacaftor, and ivacaftor), they are receiving a therapy with an unknown clinical efficacy and safety profile,” said Dr. Bermingham, a pulmonary and critical care fellow at the Medical University of South Carolina, Charleston.

Lung transplant referral guidelines recommend that physicians initiate discussions about the potential benefit of lung transplant when FEV₁ drops below 50% of the predicted value. Patients should be referred for a transplant when the value is below 50% and rapidly declining (>20% decline in the past 12 months), when it drops below 40% with accompanying predictors of shortened survival, or when it drops below 30%. The guidelines were published before approval of triple combination therapy.

The researchers conducted an open-label retrospective analysis of 60 patients started on triple combination therapy between September 2019 and February 2020 at three centers in the Southeast. They compared percent predicted ppFEV₁ values prior to initiation of therapy to ppFEV₁ values obtained 2-12 weeks after the start of therapy. Patients on therapy were compared with 10 genetically ineligible controls. The two groups were generally similar aside from genetic status, though 100% of the therapy group had pancreatic insufficiency, compared with 90% of controls (P = .013).

The therapeutic group experienced a 7.8% increase in ppFEV₁ after starting therapy (P < .001), compared with a 0.5% decrease in controls (P = .65). Before initiation of therapy, 33% of the therapy group met the criteria for initiating a transplant discussion, while 67% had been recommended for transplant. After therapy, 55% met the criteria for discussion, 33% were recommended for transplant, and 12% no longer met the criteria for discussion of transplantation. Fifty percent of controls were in discussion, and this dropped to 40%, while 50% were referred for transplantation, and this increased to 60%. On therapy, transplant referral candidates had an increase of forced vital capacity from 48.9 to 59.16 (P < .001).

Adverse events were rare, with only one discontinuation that occurred following a lung transplant and was not believed to be treatment related.

“Our study had a large number of patients taken from multiple centers, which suggests generalizabilty and real-world experience,” said Dr. Bermingham.

The results are encouraging, said Robert J. Giusti, MD, clinical professor of pediatrics at the New York University and director of the Pediatric Cystic Fibrosis Center.

“We’re all remarking how wonderful patients feel these days. It’s really a disease-altering treatment. But for the high-risk group, whose FEV₁ is less than 40%, those are the patients we’re more concerned about because we thought maybe they had too much lung disease, and that they wouldn’t benefit from triple combination. But they seem to be improving, so that’s very reassuring,” said Dr. Giusti, who was not involved in the study.

The study received funding from the Cystic Fibrosis Foundation and Dartmouth College. Dr. Bermingham and Dr. Giusti have no relevant financial disclosures.

Pilonidal disease (PD) is common in Turkey. In a study in Turkey, 19,013 young patients aged 17 to 28 years were examined; PD was detected in 6.6% of patients (0.37% of females in the cohort and 6.23% of males).¹ The incidence of PD in military personnel (women 18 years and older; men 22 years and older) is remarkably higher, with an incidence of 9% reported in Turkish soldiers.²

Pilonidal disease has become common in Turkish adolescents, who now experience an increase in desk time because of computer use and a long duration of preparation for high school and university entrance examinations. In adolescent and adult population studies, Yildiz et al³ and Harlak et al⁴ reported that sitting for 6 hours or more per day was found to significantly increase the risk for PD compared to the control group (P=.028 and P<.001, respectively).

Surgery for PD often is followed by a considerable and unpleasant postoperative course, with a long period of limited physical activity, loss of school time, and reduced social relationships. The recurrence rate of PD is reported to be as high as 40% to 50% after incision and drainage, 40% to 55% with rigorous hygiene and weekly shaving, and as high as 30% following operative intervention. Drawbacks of operative intervention include associated morbidity; lost work and school time; and prolonged wound healing, which can take days to months.^5-7

For these reasons, minimally invasive surgical techniques have become popular for treating PD in adolescents, as surgery can cause less disruption of the school and examination schedule and provide an earlier return to normal activities. Gips et al⁸—who operated on 1358 adults using skin trephines to extirpate pilonidal pits and the underlying fistulous tract and hair debris—reported a low recurrence rate and good postoperative functional outcomes with this technique. Herein, we present our short-duration experience with the Gips procedure of minimally invasive sinusectomy in adolescent PD.

Methods

Patients
We performed a retrospective medical record review of patients with symptomatic PD who were treated in our clinic between January 2018 and February 2019 using the Gips procedure of minimally invasive sinusectomy. We identified 19 patients younger than 17 years. Patients with acute inflammation and an acute undrained collection of pits were treated with incision and drainage, with close clinical follow-up until inflammation resolved. We also recommended that patients take a warm sitz bath at least once daily and chemically epilate the hair in the affected area if they were hirsute.

Gips Procedure
For all patients, the Gips procedure was performed in the left lateral position under general anesthesia using a laryngeal mask airway for anesthesia. Patients were closely shaved (if hirsute) then prepared with povidone-iodine solution. First, each fistulous opening was probed to assess depth and direction of underlying tracts using a thin (0.5–1.0 mm), round-tipped probe. Next, a trephine—comprising a cylindrical blade on a handle—was used to remove cylindrical cores of tissue. All visible median pits and lateral fistulous skin openings were excised using skin trephines of various diameters (Figure, A and B). Once the pilonidal cavity was reached, attention was directed to removing all residual underlying tissue—granulation tissue, debris, and hair—through all available accesses. The cavity was cleaned with hydrogen peroxide and normal saline. Then, all trephine-made openings were left unpacked or were packed for only a few hours and were not sutured (Figure, C and D); a light gauze bandage was eventually applied with a minimum of tape and skin traction. Patients were kept supine during a 1- or 2-hour clinical observation period before they were discharged.

Results

Of the 19 patients who underwent the Gips procedure, 17 (90%) were male; 2 (10%) were female. The mean (standard deviation [SD]) body mass index was 25 (3.7). (Body mass index was calculated as weight in kilograms divided by height in meters squared.) The mean age (SD) of patients was 15 (1.1) years (range, 12–17 years). The most common symptom at presentation was purulent discharge (11/19 [58%]). Other common symptoms included pain (8/19 [42%]), pilonidal abscess (6/19 [32%]), and bleeding (4/19 [21%]). Nine patients (47%) had prior abscess drainage at presentation; 1 (5%) had previously undergone surgery, and 5 (26%) previously had phenol injections.

The median (SD) length of stay in the hospital was 15 (3.2) hours (range, 11–22 hours). The mean (SD) time before returning to daily activities and school was 2 (0.6) days (range, 1–3 days). In our patients, the Gips procedure was performed on either a Thursday or more often a Friday; therefore, patients could be scheduled to be discharged from the hospital and return to home the next day, and then return to school on Monday. All patients were advised to take an oral analgesic for 2 days following the procedure.

The mean (SD) duration of the operative procedure was 14 (3) minutes (range, 10–20 minutes). One patient (5%) developed bleeding that ceased spontaneously. The mean (SD) complete wound healing time was 3 (0.6) weeks (range, 2–4 weeks).

Postoperative clinical examination and telephone interviews were performed for follow-up. The mean follow-up period was 5 months (range, 1–13 months); 17 of 19 patients (89%) made a complete recovery. Two patients (11%) reported recurrence in the third and fourth months following the procedure and were treated with a repeat Gips procedure 6 months after the first treatment. Improvement was noted after a second Gips procedure in 1 of 2 patients who had recurrence, leaving the success rate of the procedure in our practice at 95% (18/19).

Comment

Treatment Options for PD
Various treatment methods for PD have been postulated,^5-7 including incision and drainage, hair removal and hygiene alone, excision and primary wound closure, excision and secondary wound closure, and various flap techniques. More recently, there has been a dramatic shift to management of patients with PD in an outpatient setting. The Gips procedure, an innovative minimally surgical technique for PD, was introduced in 2008 based on a large consecutive series of more than 1300 patients.⁸ Studies have shown promising results and minimal recovery time for the Gips procedure in adult and pediatric patients.^8-10

Nevertheless, conventional excision down to the sacral fascia, with or without midline or asymmetrical closure, is still the procedure performed most often for PD worldwide.^5,10 This surgery often requires general anesthesia and a long period of postoperative care; furthermore, children who undergo conventional excision at this age generally experience lengthy periods of missing school. In addition, conventional excision is associated with a notable recurrence rate and a potentially unacceptable cosmetic result.^10,11 Therefore, we prefer the Gips procedure of minimally invasive sinusectomy to treat PD in adolescents.

A larger study from an Israeli military pilonidal sinus clinic, in which 1358 adult PD patients were treated with the Gips procedure under local anesthesia, showed a recurrence rate of 13% at 5 years and 16% at 10 years.⁸Di Castro et al¹⁰ reported use of the same technique on 2347 patients and demonstrated a recurrence rate of 5.8% at a median follow-up of 16 months. Speter et al⁹ compared minimal incision using trephines and wide excision on a matched cohort of 42 adolescent patients (mean age, 16 years). Findings indicated better functional outcomes, shorter duration of analgesia required (≤48 hours), and fewer sick days in the minimal incision group but failed to demonstrate a statistically significant difference in overall recurrence. An overall favorable outcome was reported in 61.9% (26/42) of patients in the minimal incision group and 45% (19/42) in the wide excision group. Reoperation was performed in 28% (12/42) of patients in the minimal incision group and 9% (4/42) of the wide excision group.⁹ Delshad et al⁵ found that pit-picking procedures resolved pilonidal symptoms in 92% (47/51) of patients, without recurrence at 5 months on average.

Advantages of the Gips Procedure
Advantages of the Gips procedure are numerous. It is easily applicable, inexpensive, well tolerated, and requires minimal postoperative care. Placing the patient in the lateral position for the procedure—rather than the prone position that is required for more extensive surgical procedures—is highly feasible, permitting the easy application of a laryngeal mask for anesthesia. The Gips procedure can be performed on patients with severe PD after a period of improved hygiene and hair control and allows for less morbidity than older surgical techniques. Overall, results are satisfactory.

Health services and the hospital admissions process are less costly in university hospitals in Turkey. This procedure costs an average of 400 Turkish liras (<US $50). For that reason, patients in our review were discharged the next day; however, patients could be discharged within a few hours. In the future, it is possible for appropriate cases to be managed in an outpatient setting with sedation and local anesthesia only. Because their postoperative courses are eventless, these patients can be managed without hospitalization.

Recovery is quick and allows for early return to school and other physical activities. Because the procedure was most often performed on the last school day of the week, we did not see any restriction of physical or social activities in our patients.

Lastly, this procedure can be applied to PD patients who have previously undergone extensive surgery or phenol injection, as was the case in our patients.

Conclusion

The Gips procedure is an easy-to-use technique in children and adolescents with PD. It has a high success rate and places fewer restrictions on school and social activities than traditional surgical therapies.

Patients
We performed a retrospective medical record review of patients with symptomatic PD who were treated in our clinic between January 2018 and February 2019 using the Gips procedure of minimally invasive sinusectomy. We identified 19 patients younger than 17 years. Patients with acute inflammation and an acute undrained collection of pits were treated with incision and drainage, with close clinical follow-up until inflammation resolved. We also recommended that patients take a warm sitz bath at least once daily and chemically epilate the hair in the affected area if they were hirsute.

Gips Procedure
For all patients, the Gips procedure was performed in the left lateral position under general anesthesia using a laryngeal mask airway for anesthesia. Patients were closely shaved (if hirsute) then prepared with povidone-iodine solution. First, each fistulous opening was probed to assess depth and direction of underlying tracts using a thin (0.5–1.0 mm), round-tipped probe. Next, a trephine—comprising a cylindrical blade on a handle—was used to remove cylindrical cores of tissue. All visible median pits and lateral fistulous skin openings were excised using skin trephines of various diameters (Figure, A and B). Once the pilonidal cavity was reached, attention was directed to removing all residual underlying tissue—granulation tissue, debris, and hair—through all available accesses. The cavity was cleaned with hydrogen peroxide and normal saline. Then, all trephine-made openings were left unpacked or were packed for only a few hours and were not sutured (Figure, C and D); a light gauze bandage was eventually applied with a minimum of tape and skin traction. Patients were kept supine during a 1- or 2-hour clinical observation period before they were discharged.

Results

Of the 19 patients who underwent the Gips procedure, 17 (90%) were male; 2 (10%) were female. The mean (standard deviation [SD]) body mass index was 25 (3.7). (Body mass index was calculated as weight in kilograms divided by height in meters squared.) The mean age (SD) of patients was 15 (1.1) years (range, 12–17 years). The most common symptom at presentation was purulent discharge (11/19 [58%]). Other common symptoms included pain (8/19 [42%]), pilonidal abscess (6/19 [32%]), and bleeding (4/19 [21%]). Nine patients (47%) had prior abscess drainage at presentation; 1 (5%) had previously undergone surgery, and 5 (26%) previously had phenol injections.

The median (SD) length of stay in the hospital was 15 (3.2) hours (range, 11–22 hours). The mean (SD) time before returning to daily activities and school was 2 (0.6) days (range, 1–3 days). In our patients, the Gips procedure was performed on either a Thursday or more often a Friday; therefore, patients could be scheduled to be discharged from the hospital and return to home the next day, and then return to school on Monday. All patients were advised to take an oral analgesic for 2 days following the procedure.

The mean (SD) duration of the operative procedure was 14 (3) minutes (range, 10–20 minutes). One patient (5%) developed bleeding that ceased spontaneously. The mean (SD) complete wound healing time was 3 (0.6) weeks (range, 2–4 weeks).

Postoperative clinical examination and telephone interviews were performed for follow-up. The mean follow-up period was 5 months (range, 1–13 months); 17 of 19 patients (89%) made a complete recovery. Two patients (11%) reported recurrence in the third and fourth months following the procedure and were treated with a repeat Gips procedure 6 months after the first treatment. Improvement was noted after a second Gips procedure in 1 of 2 patients who had recurrence, leaving the success rate of the procedure in our practice at 95% (18/19).

Comment

Treatment Options for PD
Various treatment methods for PD have been postulated,^5-7 including incision and drainage, hair removal and hygiene alone, excision and primary wound closure, excision and secondary wound closure, and various flap techniques. More recently, there has been a dramatic shift to management of patients with PD in an outpatient setting. The Gips procedure, an innovative minimally surgical technique for PD, was introduced in 2008 based on a large consecutive series of more than 1300 patients.⁸ Studies have shown promising results and minimal recovery time for the Gips procedure in adult and pediatric patients.^8-10

Nevertheless, conventional excision down to the sacral fascia, with or without midline or asymmetrical closure, is still the procedure performed most often for PD worldwide.^5,10 This surgery often requires general anesthesia and a long period of postoperative care; furthermore, children who undergo conventional excision at this age generally experience lengthy periods of missing school. In addition, conventional excision is associated with a notable recurrence rate and a potentially unacceptable cosmetic result.^10,11 Therefore, we prefer the Gips procedure of minimally invasive sinusectomy to treat PD in adolescents.

A larger study from an Israeli military pilonidal sinus clinic, in which 1358 adult PD patients were treated with the Gips procedure under local anesthesia, showed a recurrence rate of 13% at 5 years and 16% at 10 years.⁸Di Castro et al¹⁰ reported use of the same technique on 2347 patients and demonstrated a recurrence rate of 5.8% at a median follow-up of 16 months. Speter et al⁹ compared minimal incision using trephines and wide excision on a matched cohort of 42 adolescent patients (mean age, 16 years). Findings indicated better functional outcomes, shorter duration of analgesia required (≤48 hours), and fewer sick days in the minimal incision group but failed to demonstrate a statistically significant difference in overall recurrence. An overall favorable outcome was reported in 61.9% (26/42) of patients in the minimal incision group and 45% (19/42) in the wide excision group. Reoperation was performed in 28% (12/42) of patients in the minimal incision group and 9% (4/42) of the wide excision group.⁹ Delshad et al⁵ found that pit-picking procedures resolved pilonidal symptoms in 92% (47/51) of patients, without recurrence at 5 months on average.

Advantages of the Gips Procedure
Advantages of the Gips procedure are numerous. It is easily applicable, inexpensive, well tolerated, and requires minimal postoperative care. Placing the patient in the lateral position for the procedure—rather than the prone position that is required for more extensive surgical procedures—is highly feasible, permitting the easy application of a laryngeal mask for anesthesia. The Gips procedure can be performed on patients with severe PD after a period of improved hygiene and hair control and allows for less morbidity than older surgical techniques. Overall, results are satisfactory.

Health services and the hospital admissions process are less costly in university hospitals in Turkey. This procedure costs an average of 400 Turkish liras (<US $50). For that reason, patients in our review were discharged the next day; however, patients could be discharged within a few hours. In the future, it is possible for appropriate cases to be managed in an outpatient setting with sedation and local anesthesia only. Because their postoperative courses are eventless, these patients can be managed without hospitalization.

Recovery is quick and allows for early return to school and other physical activities. Because the procedure was most often performed on the last school day of the week, we did not see any restriction of physical or social activities in our patients.

Lastly, this procedure can be applied to PD patients who have previously undergone extensive surgery or phenol injection, as was the case in our patients.

Conclusion

The Gips procedure is an easy-to-use technique in children and adolescents with PD. It has a high success rate and places fewer restrictions on school and social activities than traditional surgical therapies.

The number of primary care providers is increasing per capita in the United States, but they are still disproportionately concentrated in urban centers, researchers say.

The finding may provide some reassurance for those who have worried about a shortage of health care workers and whether they will be able to meet the nation’s growing burden of chronic diseases.

“Access to primary care doctors is critical to population health and to reduce health care disparities in this country,” said Donglan Zhang, PhD, an assistant professor of public health at the University of Georgia, Athens.

However, many counties remain underserved, Dr. Zhang said in an interview. The need for primary care in the United States is increasing not only with population growth but because the population is aging.

Dr. Zhang and colleagues published the finding in JAMA Network Open.

Many previous reports have warned of a shortage in primary care providers. To examine recent trends in the primary care workforce, Dr. Zhang and colleagues obtained data on all the primary care clinicians registered with the Centers for Medicare & Medicaid Services from 2009 to 2017.

For the study, the researchers included general practitioners, family physicians and internists without subspecialties, nurse practitioners, and physician assistants. They then compared the number of providers with the number of residents in each county as recorded by the US Census, using urban or rural classifications for each county from the Centers for Disease Control and Prevention.

Because the U.S. Health Resources and Services Administration defines a primary care “shortage” as fewer than 1 primary care practitioner per 3,500 people, the researchers focused on this ratio. They found that the number of nurse practitioners and physician assistants was increasing much faster than the number of primary care physicians. This was true especially in rural areas, but the percentage increase for both nurse practitioners and physician assistants was lower in rural areas versus urban.

The researchers also found that there were more primary care physicians per capita in counties with higher household incomes, a higher proportion of Asian residents, and a higher proportion of college graduates.

They didn’t find a significant association between the median household income and per capita number of nurse practitioners.

They found that counties with a higher proportion of Black and Asian residents had a higher number of nurse practitioners per capita. But they found an opposite association between the proportion of Black residents and the number of physician assistants per capita.

The authors hypothesized that health care reform, particularly the passage of the Affordable Care Act in 2010, may explain the recent increase in the primary care workforce. The legislation expanded the number of people with health insurance and provided incentives for primary and preventive care.

Another factor behind the increase in the primary care workforce could be state laws that have expanded the scope of practice for nurse practitioners and primary care providers, she said.
 

Numbers may overestimate available care

The gap between rural and urban areas could be even wider than this study suggests, Ada D. Stewart, MD, president of the American Academy of Family Physicians, said in an interview. Many nurse practitioners and physician assistants don’t actually practice primary care, but instead assist physicians in other specialties such as orthopedics or general surgery.

“They are part of a team and I don’t want to diminish that at all, but especially when we talk about infant and maternal mortality, family physicians need to be there themselves providing primary care,” she said. “We’re there in hospitals and emergency rooms, and not just taking care of diabetes and hypertension.”

In addition, the primary care workforce may have been reduced since the conclusion of the study period (Dec. 31, 2017) as a result of the COVID-19 pandemic forcing some primary care physicians into retirement, Dr. Stewart said.

Measures that could help reduce the disparity include a more robust system of teaching health centers in rural counties, higher reimbursement for primary care, a lower cost of medical education, and recruiting more people from rural areas to become physicians, Dr. Stewart said.

Telehealth can enhance health care in rural areas, but many people in rural areas lack internet or cellular service, or don’t have access to computers. “We don’t want to create another healthcare disparity,” she said.

And physicians can get to know their patients’ needs better in a face-to-face visit, she said. “Telehealth does have a place, but it does not replace that person-to-person visit.”

This study was funded by National Institute on Minority Health and Health Disparities. Dr. Zhang and Dr. Stewart disclosed no relevant financial relationships.

The Oct. 5, 2020 move by the Food and Drug Administration’s Center for Drug Evaluation and Research (CDER) suggesting the withdrawal of the approval of Makena incited some opposition.

herjua/Thinkstock

Amag Pharmaceuticals’ 17 alpha-hydroxyprogesterone caproate (17OHP) injection received accelerated approval in 2011 to reduce the risk of recurrent preterm birth in women with previous unexplained preterm birth. Makena is the only drug approved for preventing recurrent preterm birth.
 

The back story

The approval was based on findings from a randomized, placebo-controlled trial that demonstrated a 34% relative risk reduction in births before 37 weeks – from 55% in the placebo arm to 36% in the 17OHP-treated arm.

The trial was not designed to measure neonatal outcomes, with the surrogate outcome of recurrent preterm birth being determined as “reasonably likely” to predict benefit to the neonate.

Subsequently, results of the required postapproval confirmatory PROLONG trialproduced conflicting results, failing to show a benefit of 17OHP on either preterm birth or neonatal outcome, which prompted the proposed withdrawal of the drug’s approval.

The CDER advisory committee agreed unanimously that the PROLONG trial did not support the clinical benefit of 17OHP, but the committee was not unanimous in deciding what to do. Of the 16 members, 9 voted to withdraw the drug’s approval, while seven voted to retain it and require another confirmatory trial.

When CDER recommends withdrawal, the company can request a public hearing, which it has done. The FDA commissioner will recommend whether to grant this request.

In the meantime, the New England Journal of Medicine has published opposing views on withdrawal of FDA approval of 170HP: one from a group of three doctors who are against it and the other from the CDER.
 

Arguments from the opposing views

“We sympathize with women who are at risk for recurrent preterm birth that could result in death or significant lifelong health effects in neonates, but retaining on the market a drug not shown to be effective for this use does not protect or promote their health,” wrote Christina Chang, MD, MPH and associates from CDER.

On the other hand, “the widespread use of 17OHP after accelerated approval has not uncovered important safety signals,” countered Michael F. Greene, MD, from Massachusetts General Hospital, Boston; David Harrington, PhD, from the Harvard T. Chan School of Public Health, Boston; and Mark A. Klebanoff, MD, MPH, who was coauthor on the original preapproval study and is with Nationwide Children’s Hospital, the Ohio State University College of Medicine, and Ohio State University College of Public Health, all in Columbus. “Withdrawal of the approval for 17OHP, as imperfect as it may be, will leave a very vulnerable demographic group of U.S. women at high risk for this complication of pregnancy with absolutely no available therapeutic option.”

While both the preapproval study and postapproval PROLONG trial had the same enrollment criteria – namely women with a singleton pregnancy and previous singleton spontaneous preterm birth – all parties acknowledged that the studies ended up with very different cohorts. Approval of the drug in the United States made it difficult to recruit U.S. participants for the second trial “because of a lack of equipoise perceived by health care providers and patients,” noted Dr. Greene and associates, resulting in 75% of the PROLONG study’s cohort coming from Europe. This meant that 59% of those in the first study were non-Hispanic black compared with just 6.6% in the PROLONG study, a difference that is important because of the increased risk of preterm birth in Black women.

“Black women are generally underrepresented in U.S. clinical trials, and they are clearly underrepresented in the PROLONG study,” noted Dr. Greene and colleagues, adding that “the total number of qualifying composite neonatal outcome events among Blacks or African Americans in the entire PROLONG study population of 1,700 participants was 9 (6 of 69 in the 17OHP group and 3 of 40 in the placebo group). This is not a robust database from which to conclude that there is no effect in Black women.”

But, Dr. Chang and the CDER group argued, while the first study showed 17OHP “reduced the risk of recurrent preterm birth in both Black and non-Black participants, the lack of even a trend toward efficacy among either Black or non-Black women in [the PROLONG study] argues that the smaller proportion of Black women [in the PROLONG study] does not explain the lack of efficacy.”

In addition to race, there were other risk factors for preterm birth, such as tobacco, alcohol, and street drug use; marital status; and age that differed between the two study cohorts. Even after subcategorizing PROLONG trial participants into higher or lower risk for preterm birth based on these risk factors, Dr. Chang and associates still found no evidence of benefit to 17OHP treatment in any risk group.

Withdrawing approval of 17OHP for a recurrent preterm indication would still allow off-label prescribing, but would most likely end insurance coverage and eventually manufacturing of the drug, noted Dr. Greene and associates.

“When the majority of a population achieves little benefit from a drug, but a minority demographic group at greatest risk for a serious medical problem appears to obtain significant benefit, any decision that will ultimately make it impossible to obtain the drug should be undertaken cautiously,” they warned. “This issue is particularly pressing when that minority group may be the least able to find and financially afford work-arounds to obtain the needed medication in our complex medical system that has a history of failing to serve them well.”

Dr. Chang and associates reported they had no relevant financial disclosures. Dr. Greene and associates reported that they had no relevant conflicts of interest or financial disclosures. Dr. Greene reported he is employed by the New England Journal of Medicine as associate editor. Dr. Harrington reported being employed by the journal as statistical consultant. Dr. Klebanoff reported he was an author of the original article about 17OHP published in the journal and referenced in this article.

Klebanoff, MD, MPH, who was coauthor on the original preapproval study and is with Nationwide Children’s Hospital, the Ohio State University College of Medicine, and Ohio State University College of Public Health, all in Columbus. “Withdrawal of the approval for 17OHP, as imperfect as it may be, will leave a very vulnerable demographic group of U.S. women at high risk for this complication of pregnancy with absolutely no available therapeutic option.”

While both the preapproval study and postapproval PROLONG trial had the same enrollment criteria – namely women with a singleton pregnancy and previous singleton spontaneous preterm birth – all parties acknowledged that the studies ended up with very different cohorts. Approval of the drug in the United States made it difficult to recruit U.S. participants for the second trial “because of a lack of equipoise perceived by health care providers and patients,” noted Dr. Greene and associates, resulting in 75% of the PROLONG study’s cohort coming from Europe. This meant that 59% of those in the first study were non-Hispanic black compared with just 6.6% in the PROLONG study, a difference that is important because of the increased risk of preterm birth in Black women.

“Black women are generally underrepresented in U.S. clinical trials, and they are clearly underrepresented in the PROLONG study,” noted Dr. Greene and colleagues, adding that “the total number of qualifying composite neonatal outcome events among Blacks or African Americans in the entire PROLONG study population of 1,700 participants was 9 (6 of 69 in the 17OHP group and 3 of 40 in the placebo group). This is not a robust database from which to conclude that there is no effect in Black women.”

But, Dr. Chang and the CDER group argued, while the first study showed 17OHP “reduced the risk of recurrent preterm birth in both Black and non-Black participants, the lack of even a trend toward efficacy among either Black or non-Black women in [the PROLONG study] argues that the smaller proportion of Black women [in the PROLONG study] does not explain the lack of efficacy.”

In addition to race, there were other risk factors for preterm birth, such as tobacco, alcohol, and street drug use; marital status; and age that differed between the two study cohorts. Even after subcategorizing PROLONG trial participants into higher or lower risk for preterm birth based on these risk factors, Dr. Chang and associates still found no evidence of benefit to 17OHP treatment in any risk group.

Withdrawing approval of 17OHP for a recurrent preterm indication would still allow off-label prescribing, but would most likely end insurance coverage and eventually manufacturing of the drug, noted Dr. Greene and associates.

“When the majority of a population achieves little benefit from a drug, but a minority demographic group at greatest risk for a serious medical problem appears to obtain significant benefit, any decision that will ultimately make it impossible to obtain the drug should be undertaken cautiously,” they warned. “This issue is particularly pressing when that minority group may be the least able to find and financially afford work-arounds to obtain the needed medication in our complex medical system that has a history of failing to serve them well.”

Dr. Chang and associates reported they had no relevant financial disclosures. Dr. Greene and associates reported that they had no relevant conflicts of interest or financial disclosures. Dr. Greene reported he is employed by the New England Journal of Medicine as associate editor. Dr. Harrington reported being employed by the journal as statistical consultant. Dr. Klebanoff reported he was an author of the original article about 17OHP published in the journal and referenced in this article.
 

The most effective initial step for clearing atopic dermatitis in infants and young children involves daily bathing, followed by immediate application of a moisturizer, topical steroid, or both, according to an expert speaking at the virtual annual Coastal Dermatology Symposium.

“If they are really severe, you can do it twice-daily, but there are several studies that show there is not a huge benefit of twice-daily over once-daily,” said Eric Simpson, MD, professor of dermatology, Oregon Health & Science University, Portland.

He called this technique “soak-and-smear.” The “smear” is performed immediately after the bath when the skin is still damp, he said. When clearing is the goal, and the child has moderate to severe atopic dermatitis (AD), 0.1% triamcinolone or a similar medium potency topical steroid can be applied, and after clearing, the steroid can be switched for a moisturizer, according to Dr. Simpson.

Rather than restricting application to areas of greatest skin involvement, “put it all over,” he advised.

The clearing regimen should be continued “for a couple of more days” after the lesions have resolved, with a return visit in about a week to confirm clearing and reinforce the next steps for keeping patients clear, he added.

The next steps depend on severity. According to Dr. Simpson, severity is defined less by the extent of skin involvement at the baseline examination than the speed at which symptoms return.

For those with only mild symptoms after an extended period of clearing, moisturizer might be sufficient to prevent a significant relapse. For children with a more rapid relapse, it will be necessary to reintroduce topical steroid either every day, every other day, or twice per week.

Whether with moisturizer or with topical steroids, the soak-and-smear technique has now been validated in a recently published crossover randomized trial.

In the trial, children aged 6 months to 11 years, with moderate to severe AD, were randomized to a twice-daily bath, called the “wet method,” versus a twice-weekly bath, called the “dry method.” Both groups received a cleanser and moisturizer along with a low-potency topical steroid as needed.

After 2 weeks, the 40 evaluable patients were crossed over to the opposite bathing technique. The wet, or soak-and-smear approach, was associated with a highly significant reduction in the primary endpoint of SCORing Atopic Dermatitis (SCORAD) index, compared with the dry method (95% confidence interval, 14.9-27.6; P less than .0001). In a secondary analysis, this translated into a 30% relative reduction in favor of the wet method.

In addition, there was improvement in a caregiver assessment of the Atopic Dermatitis Quickscore (ADQ). These data show that “twice-daily baths with topical steroids and moisturizer can help in more moderate to severe population,” said Dr. Simpson, who noted that he has participated in open-label studies with the same soak-and-smear technique that have produced similar results.

Once children are clear, Dr. Simpson recommends a maintenance strategy individualized for severity. In many cases, this will involve moisturizers applied after the bath, supplemented intermittently, such as once or twice per week, with topical steroids. However, if parents find themselves resorting to daily steroids to maintain control, “that’s when you incorporate the TCIs [topical calcineurin inhibitors].”

TCIs “can help you stay at twice-per-week topical steroids,” Dr. Simpson said at the meeting, jointly presented by the University of Louisville and Global Academy for Medical Education.

TCIs also help patients avoid steroid withdrawal, a particularly common phenomenon when topical steroids are applied repeatedly to the face. He recommended a proactive approach. By applying TCIs to areas where skin lesions frequently recur, such as the eyelids, flares can often be prevented.

Repeated applications of TCIs “is perfectly safe and effective, and there are many studies that show proactive treatment is very effective and can prevent you from having to use too much topical steroids” or move to a systemic steroid, Dr. Simpson said.

These steps have been highly effective for sustained control even in challenging cases of AD, but he emphasized the importance of explaining the rationale to parents and eliciting their adherence to these treatment steps. Writing out the instructions will reduce confusion and help parents keep their children clear, he added.

Lawrence F. Eichenfield, MD, professor of pediatrics and dermatology at the University of California, San Diego, agreed that this recently published crossover trial has been helpful in counseling parents about how to manage AD in their children.

There were more new cases of COVID-19 reported in children during the week ending Oct. 29 than any other week during the pandemic, the American Academy of Pediatrics announced Nov. 2.

For the week, over 61,000 cases were reported in children, bringing the number of COVID-19 cases for the month of October to nearly 200,000 and the total since the start of the pandemic to over 853,000, the AAP and the Children’s Hospital Association said in their weekly report.

“These numbers reflect a disturbing increase in cases throughout most of the United States in all populations, especially among young adults,” Yvonne Maldonado, MD, chair of the AAP Committee on Infectious Diseases, said in a separate statement. “We are entering a heightened wave of infections around the country. We would encourage family holiday gatherings to be avoided if possible, especially if there are high-risk individuals in the household.”

For the week ending Oct. 29, children represented 13.3% of all cases, possibly constituting a minitrend of stability over the past 3 weeks. For the full length of the pandemic, 11.1% of all COVID-19 cases have occurred in children, although severe illness is much less common: 1.7% of all hospitalizations (data from 24 states and New York City) and 0.06% of all deaths (data from 42 states and New York City), the AAP and CHA report said.

Other data show that 1,134 per 100,000 children in the United States have been infected by the coronavirus, up from 1,053 the previous week, with state rates ranging from 221 per 100,000 in Vermont to 3,321 in North Dakota. In Wyoming, 25.5% of all COVID-19 cases have occurred in children, the highest of any state, while New Jersey has the lowest rate at 4.9%, the AAP/CHA report showed.

In the 10 states making testing data available, children represent the lowest percentage of tests in Iowa (5.0%) and the highest in Indiana (16.9%). Iowa, however, has the highest positivity rate for children at 14.6%, along with Nevada, while West Virginia has the lowest at 3.6%, the AAP and CHA said in the report.

These numbers, however, may not be telling the whole story. “The number of reported COVID-19 cases in children is likely an undercount because children’s symptoms are often mild and they may not be tested for every illness,” the AAP said in its statement.

“We urge policy makers to listen to doctors and public health experts rather than level baseless accusations against them. Physicians, nurses and other health care professionals have put their lives on the line to protect our communities. We can all do our part to protect them, and our communities, by wearing masks, practicing physical distancing, and getting our flu immunizations,” AAP President Sally Goza, MD, said in the AAP statement.

A gel derived from birch bark is the first topical medication ever tested in the treatment of epidermolysis bullosa (EB) to heal wounds faster than placebo. The results come from the largest double-blind, randomized trial performed in this patient population.

Dr. Dedee Murrell

More than 41% of EB target wounds that were treated with Oleogel-S10 healed within 45 days, compared with about 29% of target wounds treated with placebo, in the EASE phase 3 trial, conducted at 58 sites in 28 countries.

A group of rare genetic disorders, EB “is described as the worst disease you’ve never heard of,” explained lead investigator Dedee Murrell, MD, director of dermatology, St. George Hospital at the University of New South Wales, Sydney. “It starts in children and is like having burns that heal with scars, and no treatment has been approved for it” by the Food and Drug Administration.

“This is the first large clinical trial with placebo of a topical treatment that’s worked for this terrible disease,” Dr. Murrell said in an interview. She noted that standard EB treatment currently consists of applying nonstick dressings to wounds to protect skin from trauma and infection.

Dr. Murrell, who has focused her work on EB patients since 1990, presented the findings at the virtual annual Congress of the European Academy of Dermatology and Venereology.

The trial enrolled 223 patients (average age, 12 years, but ages ranged to 81 years) with three types of EB, including dystrophic and junctional EB and Kindler syndrome. For each participant, a target wound was selected for use as the primary efficacy endpoint. Those wounds had a partial thickness of between 10 cm² and 50 cm² and lasted between 21 days and 9 months. Patients were stratified into groups depending on type of EB and size of target wound.

Participants were randomly assigned to receive either Oleogel-S10 (n = 109) or placebo (n = 114). All applied the blinded-study gel to all their wounds at least every 4 days at the time dressings were changed.

The primary endpoint was the percentage of patients whose target wounds completely closed within 45 days. Key secondary endpoints included time to wound healing and percentage of target wounds that healed within 90 days of treatment; incidence and severity of target wound infection; change in total body wound burden, as measured by the Epidermolysis Bullosa Disease Activity and Scarring Index skin activity subscore; change in itching, as measured by the Itch Man Scale and the Leuven Itch Scale; and adverse events.

Nearly 92% of patients who were treated with Oleogel-S10 completed the double-blind phase of the trial, compared with nearly 87% who received placebo. As noted, the primary endpoint was met, with 41.3% of Oleogel-S10 patients achieving target wound closure within 45 days, compared with 28.9% of the patients who received placebo (P = .013).

But the difference in time to wound healing by day 90 between the two patient groups was not statistically significant (P = .302), with 50.5% of Oleogel-S10 patients achieving wound closure vs. 43.9% of control patients.

Target-wound infection occurred in eight participants, including three who used Oleogel-S10 and five who received placebo; all moderate or severe infections occurred in patients who received placebo. Total wound burden was reduced to a greater extent among Oleogel-S10 patients by day 60, but there was no apparent difference at day 90.

Both treatment groups reported qualitative improvements in itch, with no significant differences between groups. The prevalence of adverse events was also similar between groups (Oleogel-S10, 81.7%; placebo, 80.7%). The most frequently reported adverse events among Oleogel-S10 patients, compared with patients who received placebo, were wound complications, pyrexia, wound infection, pruritus, and anemia; only 4.5% of adverse events were deemed severe.

Dr. Murrell said that, on the basis of the trial results, she expects the FDA to fast-track approval of Oleogel-S10, which contains triterpene extract and sunflower oil.

The gel is “a treatment patients will be able to put under their dressings, added to normal treatment, which will accelerate their wound healing, with no significant increase in any side effects,” she added.

Jemima Mellerio, MD, of St. Thomas’ Hospital in London who sees about 400 EB patients each year, agreed with Dr. Murrell that the results are “very exciting.” Dr. Mellerio was not involved in the study.

“Practicing dermatologists seeing people with EB will have something to offer that appears to speed up wound healing in chronic wounds,” Dr. Mellerio said in an interview. “It’s a positive option rather than just supportive treatment, something that makes a difference to the natural history of wounds.”

She said the trial’s biggest strength was including “such a large cohort of patients.

“It’s extremely difficult to do that kind of study, especially with a placebo-controlled arm and especially in a rare disease,” Dr. Mellerio said. “If you think about the product itself, it’s easy to apply, so it’s not particularly onerous for people to add to their daily regimen of dressings.”

The study was funded by Amryt Pharma. Dr. Murrell is an advisory board member for Amryt Pharma. Dr. Mellerio is a consultant for Amryt Pharma.

The most frequently reported adverse events among Oleogel-S10 patients, compared with patients who received placebo, were wound complications, pyrexia, wound infection, pruritus, and anemia; only 4.5% of adverse events were deemed severe.

Dr. Murrell said that, on the basis of the trial results, she expects the FDA to fast-track approval of Oleogel-S10, which contains triterpene extract and sunflower oil.

The gel is “a treatment patients will be able to put under their dressings, added to normal treatment, which will accelerate their wound healing, with no significant increase in any side effects,” she added.

Jemima Mellerio, MD, of St. Thomas’ Hospital in London who sees about 400 EB patients each year, agreed with Dr. Murrell that the results are “very exciting.” Dr. Mellerio was not involved in the study.

“Practicing dermatologists seeing people with EB will have something to offer that appears to speed up wound healing in chronic wounds,” Dr. Mellerio said in an interview. “It’s a positive option rather than just supportive treatment, something that makes a difference to the natural history of wounds.”

She said the trial’s biggest strength was including “such a large cohort of patients.

“It’s extremely difficult to do that kind of study, especially with a placebo-controlled arm and especially in a rare disease,” Dr. Mellerio said. “If you think about the product itself, it’s easy to apply, so it’s not particularly onerous for people to add to their daily regimen of dressings.”

The study was funded by Amryt Pharma. Dr. Murrell is an advisory board member for Amryt Pharma. Dr. Mellerio is a consultant for Amryt Pharma.

A gel derived from birch bark is the first topical medication ever tested in the treatment of epidermolysis bullosa (EB) to heal wounds faster than placebo. The results come from the largest double-blind, randomized trial performed in this patient population.

Dr. Dedee Murrell

More than 41% of EB target wounds that were treated with Oleogel-S10 healed within 45 days, compared with about 29% of target wounds treated with placebo, in the EASE phase 3 trial, conducted at 58 sites in 28 countries.

A group of rare genetic disorders, EB “is described as the worst disease you’ve never heard of,” explained lead investigator Dedee Murrell, MD, director of dermatology, St. George Hospital at the University of New South Wales, Sydney. “It starts in children and is like having burns that heal with scars, and no treatment has been approved for it” by the Food and Drug Administration.

“This is the first large clinical trial with placebo of a topical treatment that’s worked for this terrible disease,” Dr. Murrell said in an interview. She noted that standard EB treatment currently consists of applying nonstick dressings to wounds to protect skin from trauma and infection.

Dr. Murrell, who has focused her work on EB patients since 1990, presented the findings at the virtual annual Congress of the European Academy of Dermatology and Venereology.

The trial enrolled 223 patients (average age, 12 years, but ages ranged to 81 years) with three types of EB, including dystrophic and junctional EB and Kindler syndrome. For each participant, a target wound was selected for use as the primary efficacy endpoint. Those wounds had a partial thickness of between 10 cm² and 50 cm² and lasted between 21 days and 9 months. Patients were stratified into groups depending on type of EB and size of target wound.

Participants were randomly assigned to receive either Oleogel-S10 (n = 109) or placebo (n = 114). All applied the blinded-study gel to all their wounds at least every 4 days at the time dressings were changed.

The primary endpoint was the percentage of patients whose target wounds completely closed within 45 days. Key secondary endpoints included time to wound healing and percentage of target wounds that healed within 90 days of treatment; incidence and severity of target wound infection; change in total body wound burden, as measured by the Epidermolysis Bullosa Disease Activity and Scarring Index skin activity subscore; change in itching, as measured by the Itch Man Scale and the Leuven Itch Scale; and adverse events.

Nearly 92% of patients who were treated with Oleogel-S10 completed the double-blind phase of the trial, compared with nearly 87% who received placebo. As noted, the primary endpoint was met, with 41.3% of Oleogel-S10 patients achieving target wound closure within 45 days, compared with 28.9% of the patients who received placebo (P = .013).

But the difference in time to wound healing by day 90 between the two patient groups was not statistically significant (P = .302), with 50.5% of Oleogel-S10 patients achieving wound closure vs. 43.9% of control patients.

Target-wound infection occurred in eight participants, including three who used Oleogel-S10 and five who received placebo; all moderate or severe infections occurred in patients who received placebo. Total wound burden was reduced to a greater extent among Oleogel-S10 patients by day 60, but there was no apparent difference at day 90.

Both treatment groups reported qualitative improvements in itch, with no significant differences between groups. The prevalence of adverse events was also similar between groups (Oleogel-S10, 81.7%; placebo, 80.7%). The most frequently reported adverse events among Oleogel-S10 patients, compared with patients who received placebo, were wound complications, pyrexia, wound infection, pruritus, and anemia; only 4.5% of adverse events were deemed severe.

Chimeric antigen receptor natural killer T (CAR NKT) cells can expand in vivo and localize to tumors in patients with relapsed/refractory neuroblastoma, according to results of an ongoing phase 1 trial.

In one of three patients treated thus far, the CAR NKT cells induced an objective response with regression of a metastatic bone lesion.

Andras Heczey, MD, of Baylor College of Medicine, Houston, and colleagues reported outcomes for the first three patients in Nature Medicine.

The three boys – two 12-year-olds and one 6-year-old – had relapsed/refractory neuroblastoma.

NKT cells were collected from the patients, then genetically engineered to express a CAR to recognize the GD2-ganglioside expressed in neuroblastomas and also to express interleukin-15, which supports NKT cell survival. The cells were expanded and reinfused back into the patients.

The initial results suggest that CAR NKT cells can be used safely to treat neuroblastomas and perhaps other solid tumors, investigators said.
 

‘A significant advance’ if confirmed

Treating solid tumors with CAR T cells has been a challenge, in part because of inefficient trafficking into tumors.

However, NKT cells naturally migrate to tumors in response to tumor-derived chemokines, Dr. Heczey and colleagues noted. NKT cells kill macrophages associated with tumor growth and promote NK- and T-cell–mediated antitumor responses.

“We decided to leverage this intrinsic property of NKTs and to arm them with an additional bullet – the so-called CAR – to further potentiate their capacity to destroy the tumor,” investigator Gianpietro Dotti, MD, of the University of North Carolina Lindberger Comprehensive Cancer Center in Chapel Hill, said in a press release.

Overall, the “results are very encouraging and, if confirmed in a larger cohort of patients, present a significant advance in the cell therapy field for solid tumors,” said CAR-T researcher Stephen Gottschalk, MD, of St. Jude Children’s Research Hospital in Memphis, Tenn., when asked for comment.
 

Treatment, safety, and efficacy details

NKT cells are infrequent in human peripheral blood, so the investigators stimulated the NKT cells collected from patients with alpha-galactosylceramide–pulsed irradiated peripheral blood mononuclear cells.

The final products reached a mean NKT cell purity of 95%. The proportion of cells positive for the GD2-CAR ranged from 20% to 70% across the three patients.

After lymphodepletion with cyclophosphamide/fludarabine, the patients were infused with 3 × 10⁶ CAR NKT cells/m².

The cells were well tolerated, with no dose-limiting toxicities. There were grade 3/4 adverse events, but they occurred before CAR NKT-cell infusion and were thought to be related to lymphodepletion.

NKT-cell frequency and absolute numbers increased in the peripheral blood over baseline and remained elevated at the week 4 assessment.

Two patients had stable disease at 4 weeks, but one had a partial response and a change in Curie score from 2 to 1. The patient’s SPECT- and MIBG-merged scans “revealed a dramatic reduction in the size and MIBG uptake of a bone metastasis. The patient consequently received salvage therapy and achieved a complete response that lasted approximately 6 months,” the investigators noted.

The team found higher percentages of CAR NKT cells in primary tumor and metastatic bone marrow biopsies than in peripheral blood. A high percentage of CAR NKT cells from the tumor specimen, but only a small fraction from the bone metastasis, expressed the GD2-CAR.

This research was funded by Kuur Therapeutics, Alex’s Lemonade Stand Foundation for Childhood Cancer, the American Cancer Society, Cookies for Kids’ Cancer Foundation, and the Cancer Prevention and Research Institute of Texas. Dr. Heczey, Dr. Dotti, and two other researchers are coinventors on pending patent applications for NKT cells in cancer immunotherapy that have been licensed to Kuur Therapeutics for commercial development. Dr. Gottschalk has patent applications in the fields of T-cell and/or gene therapy for cancer. He has relationships with TESSA Therapeutics, Immatics, and Tidal.

No clinically meaningful changes in laboratory values occurred in adolescents during 52 weeks on dupilumab for atopic dermatitis in a large, open-label safety study, Michael J. Cork, MBBS, PhD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.

These reassuring results from the ongoing LIBERTY AD PED-OLE study confirm that, as previously established in adults, no blood monitoring is required in adolescents on the monoclonal antibody, which inhibits signaling of interleukins-4 and -13, said Dr. Cork, professor of dermatology and head of Sheffield Dermatology Research at the University of Sheffield (England).

“The practical importance of this finding is that there are no other systemic drugs available that don’t require blood samples. Cyclosporine, methotrexate, and the others used for atopic dermatitis require a lot of blood monitoring, and they’re off-license anyway for use in children and adolescents,” he said in an interview.

Many pediatric patients are afraid of needles and have an intense dislike of blood draws. And in a pandemic, no one wants to come into the office for blood draws if they don’t need to.

“Blood draws are very different from the injection for dupilumab. Taking a blood sample is much more painful for children. The needle in the autoinjector is really, really tiny; you can hardly feel it, and with the autoinjector you can’t even see it,” noted Dr. Cork, who is both a pediatric and adult dermatologist.

This report from the ongoing LIBERTY AD PED-OLE study included 105 patients aged 12-17 years who completed 52 weeks on dupilumab (Dupixent) with assessments of hematologic and serum chemistry parameters at baseline and weeks 16 and 52.

“The results were anticipated, but we want to know the drug is safe in every age group. The immune system is different in different age groups, so we have to be really careful,” Dr. Cork said.

The clinical side-effect profile was the same as in adults, consisting mainly of mild conjunctivitis and injection-site reactions. It’s a much less problematic side effect picture than with the older drugs.

“We’re finding the conjunctivitis to be slightly less severe than in adults, maybe because we’ve learned from the first trials in adults and from clinical experience to use prophylactic therapy. There would be no child going on dupilumab now – and no adult – that I wouldn’t put on prophylactic eye drops with replacement tears. I start them 2 weeks before I start dupilumab,” the dermatologist explained.

He and others with extensive experience using the biologic agent also work closely with an ophthalmologist.

“If we see an eye problem before going on dupilumab we get an assessment and then ophthalmologic monitoring during treatment,” Dr. Cork said.

As a dermatologist specializing in atopic dermatitis, he confessed to feeling deprived over the years as he watched the multitude of targeted biologic agents being developed for psoriasis. When he became involved in the first pediatric clinical trials of dupilumab, he had a realization: “It’s a miraculous treatment.”

“The first child I put on dupilumab spent 70 days in the hospital for IV antibiotics in the prior year. Seventy days! He almost died from MRSA septicemia. His serum IgE was 155,000 kU/L. And his IgE just went down and down and down as the dupilumab took effect. It was just incredible,” he recalled.

Dr. Cork reported receiving research funding from and serving as a consultant to Sanofi and Regeneron, which fund the LIBERTY AD PED-OLE study, as well as numerous other pharmaceutical companies.

The Food and Drug Administration has approved 0.5% lotion formulation of ivermectin (Sklice) as an over-the-counter treatment for head lice infestation in patients aged 6 months and older.

Ivermectin was approved as a prescription treatment for head lice in February 2012, according to an FDA press release, and is now approved as an over-the-counter treatment through an “Rx-to-OTC” switch process. The approval was granted to Arbor Pharmaceuticals.

The expanded approval for ivermectin increases access to effective care for head lice, which is estimated to affect between 6 million and 12 million children each year in the United States, according to the Centers for Disease Control and Prevention.

“The Rx-to-OTC switch process aims to promote public health by increasing consumer access to drugs that would otherwise only be available by prescription,” Theresa Michele, MD, acting director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research, said in the press release.

The FDA also noted in the press release that “Sklice, and its active ingredient ivermectin, have not been shown to be safe or effective for the treatment or prevention of COVID-19 and they are not FDA-approved for this use.”

The drug is approved only for treating head lice, and should be used on the scalp and dry hair, according to the labeling. In the wake of the approval, ivermectin will no longer be available as a prescription drug, according to the FDA, and patients currently using prescription versions should contact their health care providers.

An Rx-to-OTC switch is contingent on the manufacturer’s data showing that the drug is safe and effective when used as directed. In addition, “the manufacturer must show that consumers can understand how to use the drug safely and effectively without the supervision of a health care professional,” according to the FDA.

“The Rx-to-OTC switch process aims to promote public health by increasing consumer access to drugs that would otherwise only be available by prescription,” Theresa Michele, MD, acting director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research, said in the press release.

The FDA also noted in the press release that “Sklice, and its active ingredient ivermectin, have not been shown to be safe or effective for the treatment or prevention of COVID-19 and they are not FDA-approved for this use.”

The drug is approved only for treating head lice, and should be used on the scalp and dry hair, according to the labeling. In the wake of the approval, ivermectin will no longer be available as a prescription drug, according to the FDA, and patients currently using prescription versions should contact their health care providers.

An Rx-to-OTC switch is contingent on the manufacturer’s data showing that the drug is safe and effective when used as directed. In addition, “the manufacturer must show that consumers can understand how to use the drug safely and effectively without the supervision of a health care professional,” according to the FDA.
