Endometrial thickness could predict cancer, guide lymph node assessment
In a retrospective study of 378 patients who had hysterectomies for EIN, those with a preoperative endometrial stripe of 20 mm or greater were two times more likely to have endometrial cancer on final pathology, and those with an endometrial thickness of 15 mm or greater were 1.8 times more likely to have cancer.
“This data suggests that increasing endometrial thickness may be a useful preoperative marker to identify who’s at higher risk of concurrent endometrial cancer. It could also be considered a criterion for selectively using a sentinel lymph node algorithm in patients with a preoperative diagnosis of EIN. However, prospective studies are warranted to further establish this association,” said Devon Abt, MD, of Beth Israel Deaconess Medical Center in Boston.
She presented the data at the Society of Gynecologic Oncology’s Virtual Annual Meeting on Women’s Cancer (Abstract 11103).
Risk of overtreatment
There are no clear consensus guidelines on lymph node assessment for patients with EIN, Dr. Abt noted. She pointed out that roughly 40% of patients with EIN are diagnosed with endometrial cancer. However, it’s usually low-stage, low-grade disease, and only about 10% of patients will have high-risk features that warrant lymph node evaluation.
“Typically, we identify patients with concurrent endometrial cancer based on intraoperative pathology, or frozen section,” Dr. Abt explained. “We then apply the Mayo criteria, which stratifies patients as high or low risk for lymph node metastasis based on pathologic criteria. ... This information helps guide our intraoperative decisions to perform, or not perform, pelvic and para-aortic lymphadenectomy.”
Dr. Abt noted, however, that “lymphadenectomy is not benign” and increases surgical time as well as the risk of complications.
Taking these factors into account, some centers have implemented routine sentinel lymph node algorithms for staging endometrial cancers, Dr. Abt said.
What she and her colleagues wanted to determine is if there is value in this practice. Should sentinel lymph node mapping and biopsy be offered routinely to all patients with a preoperative diagnosis of EIN?
Study details
Dr. Abt and colleagues conducted a retrospective, single-center study of 378 patients with EIN. Ultimately, 27% (n = 103) of the patients were diagnosed with endometrial cancer – 95% with stage 1a disease and 5% with stage 1b.
Increasing age, White race, and hypertension were significantly associated with the presence of endometrial cancer. Body mass index, parity, hormone therapy exposure, and baseline CA 125 were not.
The median preoperative endometrial thickness was 14 mm among patients with endometrial cancer and 11 mm in patients without cancer (P = .002).
Overall, 31% of the cancer cases were considered high risk for nodal metastases by Mayo criteria, but an endometrial stripe of 15 mm or higher increased the chance of being considered high risk.
The risk of cancer was 47% among patients with an endometrial stripe of at least 20 mm versus 21% among patients with a measurement below 15 mm.
Only 10 patients underwent lymph node evaluation, 5 with sentinel lymph node dissection and 5 with lymphadenectomy. Six of the 10 patients had endometrial cancer on final pathology, but none had positive lymph nodes.
“Given the low-grade and early-stage disease in this cohort, adherence to a routine sentinel lymph node algorithm in all patients with EIN would result in overtreatment,” Dr. Abt said.
Discussant Nicole Fleming, MD, of the University of Texas MD Anderson Cancer Center, Houston, said she would advocate for more selective use of sentinel lymph node biopsies in EIN as well.
Dr. Fleming said, in general, lymph node biopsy may be reasonable in settings where frozen sections are unreliable and the patient seems to be at high risk of invasive cancer. However, at academic centers with dedicated gynecologic pathologists, given the low risk of invasive cancer and the fact that lymph nodes “are probably not going to provide you a lot of useful therapeutic decision-making tools,” potentially eliminating sentinel lymph node biopsy might make sense, Dr. Fleming said.
Dr. Fleming disclosed relationships with Tesaro, Bristol-Myers Squibb, Pfizer, and GlaxoSmithKline. Dr. Abt reported having no relevant disclosures and did not report any study funding.

Despite new ichthyosis treatment recommendations, ‘many questions still exist’
.
According to a consensus statement published in the February issue of Pediatric Dermatology, adequate data exist in the medical literature to demonstrate an improvement in use of systemic retinoids for select genotypes of congenital ichthyosiform erythroderma, epidermolytic ichthyosis, erythrokeratodermia variabilis, harlequin ichthyosis, IFAP syndrome (ichthyosis with confetti, ichthyosis follicularis, atrichia, and photophobia), KID syndrome (keratitis-ichthyosis-deafness), KLICK syndrome (keratosis linearis with ichthyosis congenita and sclerosing keratoderma), lamellar ichthyosis, loricrin keratoderma, neutral lipid storage disease with ichthyosis, recessive X-linked ichthyosis, and Sjögren-Larsson syndrome.
At the same time, limited or no data exist to support the use of systemic retinoids for CHILD syndrome (congenital hemidysplasia with ichthyosiform erythroderma and limb defects), CHIME syndrome (colobomas, heart defects, ichthyosiform dermatosis, intellectual disability, and either ear defects or epilepsy), Conradi-Hunermann-Happle syndrome, ichthyosis-hypotrichosis, ichthyosis-hypotrichosis-sclerosis cholangitis, ichthyosis prematurity syndrome, MEDNIK syndrome (mental retardation, enteropathy, deafness, peripheral neuropathy, ichthyosis, and keratoderma), peeling skin disease, Refsum syndrome, and trichothiodystrophy, according to the statement.
“In particular, we did note that, with any disorder that was associated with atopy, the retinoids were often counterproductive,” one of the consensus statement cochairs, Andrea L. Zaenglein, MD, said during the Society for Pediatric Dermatology pre-AAD meeting. “In Netherton syndrome, for example, retinoids seemed to make the skin fragility a lot worse, so typically, they would be avoided in those patients.”
The statement, which she assembled with cochair pediatric dermatologist Moise L. Levy, MD, professor of pediatrics, University of Texas at Austin, and 21 other multidisciplinary experts, recommends considering use of topical retinoids to help decrease scaling of the skin,“but [they] are particularly helpful for more localized complications of ichthyosis, such as digital contractures and ectropion,” said Dr. Zaenglein, professor of dermatology and pediatrics at Penn State University, Hershey. “A lot of it has to do with the size and the volume of the tubes and getting enough [product] to be able to apply it over larger areas. We do tend to use them more focally.”
While systemic absorption can occur with widespread use, no specific lab monitoring is required. Dr. Zaenglein and her colleagues also recommend avoiding the use of tazarotene during pregnancy, since it is contraindicated in pregnancy (category X), but monthly pregnancy tests are not recommended.
During an overview of the document at the meeting, she noted that the recommended dosing for both isotretinoin and acitretin is 0.5-1.0 mg/kg per day and the side effects tend to be dose dependent, “except teratogenicity, which can occur with even low doses of systemic retinoid exposure and early on in pregnancy.” The authors also advise patients to consider drug holidays or lower doses “especially during warmer, more humid months, where you might not need the higher doses to achieve cutaneous effects,” she said.
They emphasized the importance of avoiding pregnancy for 3 years after completion of treatment with acitretin. “While the half-life of acitretin is 49 hours, it’s easily converted with any alcohol exposure to etretinate,” Dr. Zaenglein noted. “Then, the half-life is 120 days.”
The statement, which was sponsored by the Pediatric Dermatology Research Alliance (PEDRA), also addresses the clinical considerations and consequences of long-term systemic retinoid use on bone health, such as premature epiphyseal closure in preadolescent children. “In general, this risk is greater with higher doses of therapies – above 1 mg/kg per day – and over prolonged periods of time, typically 4-6 years,” she said. Other potential effects on bone health include calcifications of tendons and ligaments, osteophytes or “bone spurs,” DISH (diffuse idiopathic skeletal hyperostosis), and potential alterations in bone density and growth.
“We also have to worry about concomitant effects of contraception, particularly if you’re using progestin-only formulations that carry a black box warning for osteoporosis,” Dr. Zaenglein said. “It is recommended that you limit their use to 3 years.” Other factors to consider include genetic risk and modifiable factors that affect bone health, such as diet and physical activity, which may impact susceptibility to systemic retinoid bone toxicity and should be discussed with the patient.
Recommended bone monitoring in children starts with a comprehensive family and personal medical history for skeletal toxicity risk factors, followed by an annual growth assessment (height, weight, body mass index, and growth curve), asking regularly about musculoskeletal symptoms, and following up with appropriate imaging. “Inquiring about their diet is recommended as well, so making sure they’re getting sufficient amounts of calcium and vitamin D, and no additional vitamin A sources that may compound the side effects from systemic retinoids,” Dr. Zaenglein said.
The document also advises that a baseline skeletal radiographic survey be performed in patients aged 16-18 years. This may include imaging of the lateral cervical and thoracic spine, lateral view of the calcanei to include Achilles tendon, hips and symptomatic areas, and bone density evaluation.
The statement addressed the psychiatric considerations and consequences of long-term systemic retinoid use. One cross-sectional study of children with ichthyosis found that 30% screened positive for depression and 38% screened positive for anxiety, “but the role of retinoids is unclear,” Dr. Zaenglein said. “It’s a complicated matter, but patients with a personal history of depression, anxiety, and other affective disorders prior to initiation of systemic retinoid treatment should be monitored carefully for exacerbation of symptoms. Comanagement with a mental health provider should be considered.”
As for contraception considerations with long-term systemic retinoid therapy use, the authors recommend that two forms of contraception be used. “Consider long-acting reversible contraception, especially in sexually active adolescents who have a history of noncompliance, or to remove the risk of teratogenicity for them,” she said. “We’re not sure what additive effects progestin/lower estrogen have on long-term cardiovascular health, including lipids and bone density.”
The authors noted that iPLEDGE is not designed for long-term use. “It’s really designed for the on-label use of systemic retinoids in severe acne, where you’re using it for 5-6 months, not for 5-6 years,” Dr. Zaenglein said. “iPLEDGE does impose significant and financial barriers for our patients. More advocacy is needed to adapt that program for our patients.”
She and her coauthors acknowledged practice gaps and unmet needs in patients with disorders of cornification/types of ichthyosis, including the optimal formulation of retinoids based on ichthyosis subtype, whether there is a benefit to intermittent therapy with respect to risk of toxicity and maintenance of efficacy, and how to minimize the bone-related changes that can occur with treatment. “These are some of the things that we can look further into,” she said. “For now, though, retinoids can improve function and quality of life in patients with ichthyosis and disorders of cornification. Many questions still exist, and more data and research are needed.”
Sun Pharmaceuticals and the Foundation for Ichthyosis and Related Skin Types (FIRST) provided an unrestricted grant for development of the recommendations.
Dr. Zaenglein disclosed that she is a consultant for Pfizer. She is also an advisory board member for Dermata, Sol-Gel, Regeneron, Verrica, and Cassiopea, and has conducted contracted research for AbbVie, Incyte, Arcutis, and Pfizer. The other authors disclosed serving as investigators, advisers, consultants, and/or had other relationships with various pharmaceutical companies.

FROM THE SPD PRE-AAD MEETING
Enzymatic injections show durable improvement in buttock cellulite
follow-up in an ongoing, 5-year, phase 3b, open-label extension study, Michael H. Gold, MD, said at Innovations in Dermatology: Virtual Spring Conference 2021.
However, outcomes in that study, as well as in the earlier pivotal trials, were assessed via physician and patient subjective assessments of aesthetic appearance. In a separate presentation at the conference, Michael S. Kaminer, MD, presented a different study evaluating the objective quantifiable effects of CCH on buttock cellulite dimple volume using three-dimensional imaging. The results, indicating that smaller cellulite dimples responded better than larger dimples, he noted, were unexpected.
Discussant Zoe D. Draelos, MD, who practices in High Point, N.C., and is a consulting professor of dermatology at Duke University, Durham, N.C., put the two studies in perspective, explaining that there are multiple challenges associated with the use of CCH to treat buttock cellulite, and dermatologists need to understand them in order to maximize the benefit.
“There’s definitely a market for this therapy,” she observed, noting the plethora of over-the-counter products and devices sold for removal of cellulite. “I think if you manage patient expectations, this will be a very, very successful procedure.”
In 2020, the Food and Drug Administration approved subcutaneous injections of CCH (marketed under the brand name QWO) for treatment of cellulite in women’s buttocks on the basis of the randomized RELEASE-1 and -2 trials. But while this is a new indication for CCH, it is not a new drug. The medication has been approved for years for treatment of fibrotic band contracture disorders, namely Dupuytren’s contracture and Peyronie’s disease. The mechanism of action for treatment of cellulite involves a process dubbed enzymatic subcision, in which CCH breaks down mature collagen and stimulates new collagen formation and fat redistribution in an effort to achieve smoother skin contour.
“This adds a whole new wrinkle to injectables available in dermatology. We have fillers, we have toxins, and now we have enzymatic subcision,” Dr. Draelos commented.
Durability of effects
Dr. Gold, founder of the Gold Skin Care Center and at the Tennessee Clinical Research Center, Nashville, reported on 483 women with moderate to severe buttock cellulitis who completed the 71-day, randomized, double-blind, phase 3 RELEASE-1 or RELEASE-2 studies and then enrolled in the open-label extension study. At the end of the randomized trial, 61.7% of women experienced at least a 1-level improvement on the Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS), compared with 36.7% of placebo controls. The key finding in the interim analysis of the extension study: After the first 6 months, during which no one received any additional therapy, 52.7% of the CCH group still had at least a 1-level improvement in PR-PCSS, compared with the randomized trial baseline, as did 32.6% of controls.
Similarly, 63% of CCH-treated patients showed at least a 1-level improvement in the Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) from baseline to the end of the randomized trial, and 52.7% met that standard after 6 months off treatment in the open-label extension. In contrast, the control group had response rates of 36.7% and 32.6%. There were no long-term safety concerns, according to Dr. Gold.
Measuring cellulite dimple volume shrinkage
Dr. Kaminer and coinvestigators measured the change in cellulite dimple volume from baseline to 30 days after the final injection of 33 buttock dimples in 27 women in order to get a quantifiable sense of the effectiveness of the CCH injection. To their surprise, smaller-volume dimples up to 118 mm3 showed a mean 43% reduction in volume, a significantly better result than the 15.8% reduction seen in dimples greater than 118 mm3.
“That’s almost counterintuitive, right? You’d think that larger dimples would have a bigger improvement, but it turns out that the smaller dimples do better,” he said at the conference sponsored by MedscapeLIVE! and the producers of the Hawaii Dermatology Seminar and Caribbean Dermatology Symposium.
Also, cellulite dimples in women age 40 and under responded significantly better than those in older women, added Dr. Kaminer, a dermatologist in private practice in Chestnut Hill, Mass., who is also on the faculty at Yale University, New Haven, Conn., and Brown University, Providence, R.I.
Challenges in using CCH therapy
Dr. Draelos, who is familiar with CCH, having worked on some earlier studies of the product, commented that “this is really the first medical treatment for cellulite that’s been proven to work.”
That being said, there are challenges with this therapy. While roughly 53% of women rated themselves as having at least a 1-level improvement after 6 months of follow-up, so did 33% of placebo-treated controls, for a placebo-subtracted 20% response.
“Is a 1-grade improvement going to be enough for women to engage in this procedure? You do need to remember that it takes multiple injections: most need at least three injections to see durable impact. And there’s discomfort during the procedure and afterwards during the healing process because the mechanism of action is enzymatic. You’re breaking down fibrous bands, and that’s a proinflammatory process. Many women who undergo this procedure may have discomfort and bruising, and they should be warned that this is not a procedure to do before taking a cruise or wearing a bikini. Also, it’s important to note that many women will have discomfort in the area where they sit, so if they have a job where they need to be sitting for long periods of time they need to plan their activities around this particular procedure,” the dermatologist said.
Another consideration: “The area they actually studied – the buttocks – is an area where I’m not sure a lot of women would expose their skin in public. I think thigh dimpling is more bothersome because it shows in shorts and other types of clothing. We need to figure out if the injections work on the posterior thighs, the most common place most postpubertal women get cellulite,” Dr. Draelos noted.
She wasn’t surprised that smaller cellulite dimples did better. Larger dimples presumably have a broader fibrous attachment and tighter fibrous band. She found the less robust outcomes in women over age 40 similarly unsurprising, since cellulitis seems to worsen with age. Cellulitis can’t really be called a disease, anyway, since it occurs in about 90% of postpubertal women.
One last tip about managing patient expectations: “Let a woman know that it’ll be better, but it won’t be gone,” she said.

FROM INNOVATIONS IN DERMATOLOGY
What’s the future of telehealth? It’s ‘complicated’
pre-AAD meeting.
“We have seen large numbers of children struggle with access to school and access to health care because of lack of access to devices, challenges of broadband Internet access, culture, language, and educational barriers – just having trouble being comfortable with this technology,” said Natalie Pageler, MD, a pediatric intensivist and chief medical information officer at Stanford Children’s Health, Palo Alto, Calif.
“There are also privacy concerns, especially in situations where there are multiple families within a household. Finally, it’s important to remember that policy and reimbursement issues may have a significant effect on some of the socioeconomic barriers,” she added. “For example, many of our families who don’t have access to audio and video may be able to do a telephone call, but it’s important that telephone calls be considered a form of telehealth and be reimbursed to help increase the access to health care by these families. It also makes it easier to facilitate coordination of care. All of this leads to decreased time and costs for patients, families, and providers.”
Within the first few weeks of the pandemic, Dr. Pageler and colleagues at Stanford Children’s Health observed an increase from about 20 telehealth visits per day to more than 700 per day, which has held stable. While the benefits of telehealth are clear, many perceived barriers exist. In a study conducted prior to the COVID-19 pandemic, researchers identified a wide variety of barriers to implementation of telehealth, led by reimbursement, followed by poor business model sustainability, lack of provider time, and provider interest.
“Some of the barriers, like patient preferences for inpatient care, lack of provider interest in telehealth, and lack of provider time were easily overcome during the COVID pandemic,” Dr. Pageler said. “We dedicated the time to train immediately, because the need was so great.”
In 2018, Patrick McMahon, MD, and colleagues at Children’s Hospital of Philadelphia, launched a teledermatology program that provided direct-to-patient “E-visits” and recently pivoted to using this service only for acne patients through a program called “Acne Express.” The out-of-pocket cost to patients is $50 per consult and nearly 1,500 cases have been completed since 2018, which has saved patients and their parents an estimated 65,000 miles driving to the clinic.
“In the last year we have piloted something called “E-Consults,” which is a provider-to-provider, store-and-forward service,” said Dr. McMahon, a pediatric dermatologist and director of teledermatology at CHOP. “That service is not currently reimbursable, but it’s funded through our hospital. We also have live video visits between provider and patient. That is reimbursable. We have done about 7,500 of those.”
In a 2020 unpublished membership survey of SPD members, Dr. McMahon and colleagues posed the question, “How has teledermatology positively impacted your practice over the past year?” The top three responses were that teledermatology was safe during COVID-19, it provided easy access for follow-up, and it was convenient. In response to the question, “What is the most fundamental change needed for successful delivery of pediatric teledermatology?” the top three responses were reimbursement, improved technology, and regulatory changes.
“When we asked about struggles and difficulties, a lot of responses surrounded the lack of connectivity, both from a technological standpoint and also that lack of connectivity we would feel in person – a lack of rapport,” Dr. McMahon said. “There’s also the inability for us to touch and feel when we examine, and we worry about misdiagnosing. There are also concerns about disparities and for us being sedentary – sitting in one place staring at a screen.”
To optimize the teledermatology experience, he suggested four pillars: educate, optimize, reach out, and tailor. “I think we need to draw upon some of the digital education we already have, including a handout for patients [on the SPD website] that offers tips on taking a clear photograph on their smartphones,” he said. “We’re also trying to use some of the cases and learnings from our teledermatology experiences to teach the providers. We are setting up CME modules that are sort of a flashcard-based teaching mechanism.”
To optimize teledermatology experiences, he continued, tracking demographics, diagnoses, number of cases, and turnaround time is helpful. “We can then track who’s coming in to see us at follow-up after a new visit through telehealth,” Dr. McMahon said. “This helps us repurpose things, pivot as needed, and find any glitches. Surveying the families is also critical. Finally, we need clinical support to tee-up visits and to ensure photos are submitted and efficient, and to match diagnoses and family preference with the right modality.”
Another panelist, Justin M. Ko, MD, MBA, who chairs the American Academy of Dermatology’s Task Force on Augmented Intelligence, said that digitally enabled and artificial intelligence (AI)-augmented care delivery offers a “unique opportunity” for increasing access and increasing the value of care delivered to patients.
“The role that we play as clinicians is central, and I think we can make significant strides by doing two things,” said Dr. Ko, chief of medical dermatology for Stanford (Calif.) Health Care. “One: extending the reach of our expertise, and the second: scaling the impact of the care we deliver by clinician-driven, patient-centered, digitally-enabled, AI-augmented care delivery innovation. This opportunity for digital care transformation is more than just a transition from in-person visits to video visits. We have to look at this as an opportunity to leverage the unique aspects of digital capabilities and fundamentally reimagine how we deliver care.”
The AAD’s Position Statement on Augmented Intelligence was published in 2019.
Between March and June of 2021, Neil S. Prose, MD, conducted about 300 televisits with patients. “I had a few spectacular visits where, for example, a teenage patient who had been challenging showed me all of her artwork and we became instantly more connected,” said Dr. Prose, professor of dermatology, pediatrics, and global health at Duke University, Durham, N.C. “Then there’s the potential for a long-term improvement in health care for some patients.”
But there were also downsides to the process, he said, including dropped connections, poor picture and sound quality, patient no-shows, and patients reporting they were unable to schedule a telemedicine visit. “The problems I was experiencing were not just between me and my patients; the problems are systemic, and they have to do with various factors: the portal, the equipment, Internet access, and inadequate or no health insurance,” said Dr. Prose, past president of the SPD.
Portal-related challenges include a lack of focus on culture, literacy, and numeracy, “and these worsen inequities,” he said. “Another issue related to portal design has to do with language. Very few of the portals allow patients to participate in Spanish. This has been particularly difficult for those of us who use Epic. The next issue has to deal with the devices the patients are using. Cell phone visits can be very problematic. Unfortunately, lower-income Americans have a lower level of technology adoption, and many are relying on smartphones for their Internet access. That’s the root of some of our problems.”
To achieve digital health equity, Dr. Prose emphasized the need for federal mandates for tools for digital health access usable by underserved populations and federal policies that increase broadband access and view it as a human right. He also underscored the importance of federal policies that ensure continuation of adequate telemedicine reimbursement beyond the pandemic and urged health institutions to invest in portals that address the needs of the underserved.
“What is the future of telemedicine? The answer is complicated,” said Dr. Prose, who recommended a recently published article in JAMA on digital health equity. “There have been several rumblings of large insurers who plan to pull the rug on telemedicine as soon as the pandemic is more or less over. So, all of our projections about this being a wonderful trend for the future may be for naught if the insurers don’t step up to the table.”
None of the presenters reported having financial disclosures.

But there were also downsides to the process, he said, including dropped connections, poor picture and sound quality, patient no-shows, and patients reporting they were unable to schedule a telemedicine visit. “The problems I was experiencing were not just between me and my patients; the problems are systemic, and they have to do with various factors: the portal, the equipment, Internet access, and inadequate or no health insurance,” said Dr. Prose, past president of the SPD.
Portal-related challenges include a lack of focus on culture, literacy, and numeracy, “and these worsen inequities,” he said. “Another issue related to portal design has to do with language. Very few of the portals allow patients to participate in Spanish. This has been particularly difficult for those of us who use Epic. The next issue has to deal with the devices the patients are using. Cell phone visits can be very problematic. Unfortunately, lower-income Americans have a lower level of technology adoption, and many are relying on smartphones for their Internet access. That’s the root of some of our problems.”
To achieve digital health equity, Dr. Prose emphasized the need for federal mandates for tools for digital health access usable by underserved populations and federal policies that increase broadband access and view it as a human right. He also underscored the importance of federal policies that ensure continuation of adequate telemedicine reimbursement beyond the pandemic and urged health institutions to invest in portals that address the needs of the underserved.
“What is the future of telemedicine? The answer is complicated,” said Dr. Prose, who recommended a recently published article in JAMA on digital health equity. “There have been several rumblings of large insurers who plan to pull the rug on telemedicine as soon as the pandemic is more or less over. So, all of our projections about this being a wonderful trend for the future may be for naught if the insurers don’t step up to the table.”

“We have seen large numbers of children struggle with access to school and access to health care because of lack of access to devices, challenges of broadband Internet access, culture, language, and educational barriers – just having trouble being comfortable with this technology,” said Natalie Pageler, MD, a pediatric intensivist and chief medical information officer at Stanford Children’s Health, Palo Alto, Calif.
“There are also privacy concerns, especially in situations where there are multiple families within a household. Finally, it’s important to remember that policy and reimbursement issues may have a significant effect on some of the socioeconomic barriers,” she added. “For example, many of our families who don’t have access to audio and video may be able to do a telephone call, but it’s important that telephone calls be considered a form of telehealth and be reimbursed to help increase the access to health care by these families. It also makes it easier to facilitate coordination of care. All of this leads to decreased time and costs for patients, families, and providers.”
Within the first few weeks of the pandemic, Dr. Pageler and colleagues at Stanford Children’s Health observed an increase from about 20 telehealth visits per day to more than 700 per day, which has held stable. While the benefits of telehealth are clear, many perceived barriers exist. In a study conducted prior to the COVID-19 pandemic, researchers identified a wide variety of barriers to implementation of telehealth, led by reimbursement, followed by poor business model sustainability, lack of provider time, and provider interest.
“Some of the barriers, like patient preferences for inpatient care, lack of provider interest in telehealth, and lack of provider time were easily overcome during the COVID pandemic,” Dr. Pageler said. “We dedicated the time to train immediately, because the need was so great.”
In 2018, Patrick McMahon, MD, and colleagues at Children’s Hospital of Philadelphia, launched a teledermatology program that provided direct-to-patient “E-visits” and recently pivoted to using this service only for acne patients through a program called “Acne Express.” The out-of-pocket cost to patients is $50 per consult and nearly 1,500 cases have been completed since 2018, which has saved patients and their parents an estimated 65,000 miles driving to the clinic.
“In the last year we have piloted something called “E-Consults,” which is a provider-to-provider, store-and-forward service,” said Dr. McMahon, a pediatric dermatologist and director of teledermatology at CHOP. “That service is not currently reimbursable, but it’s funded through our hospital. We also have live video visits between provider and patient. That is reimbursable. We have done about 7,500 of those.”
In a 2020 unpublished membership survey of SPD members, Dr. McMahon and colleagues posed the question, “How has teledermatology positively impacted your practice over the past year?” The top three responses were that teledermatology was safe during COVID-19, it provided easy access for follow-up, and it was convenient. In response to the question, “What is the most fundamental change needed for successful delivery of pediatric teledermatology?” the top three responses were reimbursement, improved technology, and regulatory changes.
“When we asked about struggles and difficulties, a lot of responses surrounded the lack of connectivity, both from a technological standpoint and also that lack of connectivity we would feel in person – a lack of rapport,” Dr. McMahon said. “There’s also the inability for us to touch and feel when we examine, and we worry about misdiagnosing. There are also concerns about disparities and for us being sedentary – sitting in one place staring at a screen.”
To optimize the teledermatology experience, he suggested four pillars: educate, optimize, reach out, and tailor. “I think we need to draw upon some of the digital education we already have, including a handout for patients [on the SPD website] that offers tips on taking a clear photograph on their smartphones,” he said. “We’re also trying to use some of the cases and learnings from our teledermatology experiences to teach the providers. We are setting up CME modules that are sort of a flashcard-based teaching mechanism.”
To optimize teledermatology experiences, he continued, tracking demographics, diagnoses, number of cases, and turnaround time is helpful. “We can then track who’s coming in to see us at follow-up after a new visit through telehealth,” Dr. McMahon said. “This helps us repurpose things, pivot as needed, and find any glitches. Surveying the families is also critical. Finally, we need clinical support to tee-up visits and to ensure photos are submitted and efficient, and to match diagnoses and family preference with the right modality.”
Another panelist, Justin M. Ko, MD, MBA, who chairs the American Academy of Dermatology’s Task Force on Augmented Intelligence, said that digitally enabled and artificial intelligence (AI)-augmented care delivery offers a “unique opportunity” for increasing access and increasing the value of care delivered to patients.
“The role that we play as clinicians is central, and I think we can make significant strides by doing two things,” said Dr. Ko, chief of medical dermatology for Stanford (Calif.) Health Care. “One: extending the reach of our expertise, and the second: scaling the impact of the care we deliver by clinician-driven, patient-centered, digitally-enabled, AI-augmented care delivery innovation. This opportunity for digital care transformation is more than just a transition from in-person visits to video visits. We have to look at this as an opportunity to leverage the unique aspects of digital capabilities and fundamentally reimagine how we deliver care.”
The AAD’s Position Statement on Augmented Intelligence was published in 2019.

Fit-for-Fertility program boosts births, is cost effective
Incorporation of a nonintensive fitness intervention for women with obesity into a standard fertility treatment program could be cost effective, a new analysis finds.
Financial data for the Canadian Fit-for-Fertility program were presented March 20 at the annual meeting of the Endocrine Society by Matea Belan, PhD, of the division of endocrinology at the University of Sherbrooke (Que.).
Women with obesity and infertility are typically advised to lose 5%-10% of their body weight as first-line fertility treatment, as doing so has been shown to increase rates of ovulation and pregnancy. But most established fertility treatment programs don’t incorporate organized lifestyle modification interventions, Dr. Belan explained during a press briefing.
“Mostly they’re just given general advice, not resources. It’s up to the woman to seek help for lifestyle. Our idea is to give them access to intervention that’s integrated into the setting of a fertility clinic,” she said.
Primary results from the Fit-for-Fertility program, including significant weight loss and a 40% increased live birth rate at 18 months, compared with standard fertility treatment, were presented at ENDO 2019 and reported at the time by this news organization.
In the new analysis, the cost in Canadian dollars per additional newborn achieved with the Fit-for-Fertility program was similar to the willingness-to-pay for in vitro fertilization from a health system perspective.
The final goal, lead investigator Jean-Patrice Baillargeon, MD, said in an interview, “would be to convince stakeholders, and mainly the provincial government, to cover the costs of our lifestyle program. This would not be more costly than funding IVF, but [would provide] more long-term benefits for the whole family and the offspring.”
Chloe A. Zera, MD, said in an interview that she supports the idea in principle, but is concerned that, in the U.S. health care system, women don’t always have access to fertility and obesity treatments to begin with.
“There’s a huge equity issue. People with Medicaid don’t necessarily get coverage for IVF. ... Even many commercially insured people are paying out of pocket, which can be $10,000 to $15,000 for a cycle just for the medications, so the cost to patients on the individual level is huge,” said Dr. Zera, who is associate professor of obstetrics, gynecology, and reproductive biology at Harvard Medical School, Boston.
She added: “I’m prolifestyle modification. I’m also proequity in health care delivery so I would want to make sure that the way it’s delivered incorporates that as a consideration. ... Is that money better spent on primary prevention of obesity and access to basic services and basic reproductive health care for everybody?”
Primary results: Improvements in overall and spontaneous pregnancy rates
The study included 130 women with infertility and a body mass index of at least 30 kg/m2 (mean, 40), of whom 65 were randomized to the Fit-for-Fitness program and 65 to standard fertility treatment that did not include a lifestyle intervention, although those women could consult professionals on their own. The women in the lifestyle intervention group had to stop medical fertility treatments for the first 6 months but could use them thereafter while the controls continued to use them throughout.
Based on motivational interviewing, the program focused on womens’ individual likes and dislikes, experiences, and perceived capacities, aiming to improve healthful habits gradually and with “low intensity” so as to maintain them in the long run.
The program combined individual sessions with a nutritionist and kinesiologist every 6 weeks and 12 mandatory group sessions. The women were asked to reduce their total caloric intake by about 500 calories/day but weren’t asked to change their diets. They were also advised to increase physical activity by about 150 minutes/week.
“We want to keep it sustainable in time, so they don’t have a relapse when they become pregnant, and to help the newborn and spouse too. It’s about improving and maintaining habits,” Dr. Belan explained during the briefing.
At 6 months, mean weight changes were –3.4% versus –0.89% for the intervention versus control groups (P = .003).
“What is important for women with obesity and infertility is to improve their lifestyle, both physical activity and nutrition, even if the weight loss is minimal,” noted Dr. Baillargeon, professor of medicine, health sciences research and physiology, also at the University of Sherbrooke.
A total of 46 intervention and 52 control patients finished the 18-month study. Pregnancies occurred in 61% of the intervention group versus 39% of the controls, while spontaneous pregnancies – among those not using medical fertility treatments – occurred in 33.3% versus 12.3% (P = .009).
The primary outcome, live births at 18 months, occurred in 51.0% of the intervention group versus 36.8% of controls, which wasn’t a statistically significant difference, but was “highly clinically significant,” Dr. Belan said.
Cost per additional newborn similar to IVF
Costs (in Canadian dollars) considered in the analysis included those related to the management of infertility, obesity, pregnancy, and childbirth. The incremental cost-effectiveness ratios, a standard cost-effectiveness measure, per live birth were $24,393 from a societal perspective, $12,633 for the health system, and $5,980 for the patient.
Because the $12,633 health system cost per additional newborn with the Fit-for-Fertility program is similar to the health system’s willingness-to-pay for IVF of up to $15,000, a lifestyle intervention could be considered cost-efficient compared with the standard of care, Dr. Belan said.
“We think that the Fit-for-Fertility program could be deemed cost effective and could represent an interesting alternative to the usual standard of care for women with obesity seeking fertility treatments,” she commented.
The Canadian Institutes of Health Research is funding a larger randomized, controlled trial of the program at six Canadian centers to validate these results.
Dr. Belan, Dr. Baillargeon, and Dr. Zera reported no relevant financial relationships.

Hypofractionated radiotherapy: New normal for lung cancer?
The U.K.-based study showed that patients with stage I-III lung cancer who were set to undergo radiotherapy with curative intent were more likely to receive fewer fractions at higher doses when treated between April and October 2020. During that period, 19% of patients had their radiotherapy dose or fractionation schedule changed to deviate from standard care.
In addition, 8% of patients who were set to undergo surgery ultimately received radiotherapy instead, presumably to ease pressures on already struggling intensive care services, said Kathryn Banfill, MBChB, of Christie NHS Foundation Trust in Manchester, England.
Dr. Banfill presented results from the COVID-RT Lung study at the European Lung Cancer Virtual Congress 2021 (Abstract 203MO).
New guidelines prompt study
When the COVID-19 pandemic began, European and joint European and North American guidelines were issued to try to ensure that lung cancer patients would continue to receive the best possible treatment under the circumstances. This included guidance on how and when to use treatments such as radiotherapy.
One U.K. guideline included recommendations on the use of hypofractionation in the COVID-19 era. The recommendations focused on altering the dosage or length of radiotherapy treatments to try to reduce the number of hospital visits, thereby reducing the risk of exposing patients to SARS-CoV-2.
“The aim of these guidelines is very much to reduce the risk to patients,” Dr. Banfill said. “These patients are often at higher risk of serious COVID-19, both as a result of their cancer and also as a result of many of the coexisting medical conditions that they have, such as COPD [chronic obstructive pulmonary disease],” she explained.
The COVID-RT Lung study was essentially born out of these guidelines. The goals of the study were to see what changes to radiotherapy practice occurred as a result of the guidelines and to assess how the changes have affected patient outcomes.
Changes to diagnosis and treatment
COVID-RT Lung is an ongoing, prospective study of patients with biopsy- or imaging-proven stage I–III lung cancer who were referred for, or treated with, radical radiotherapy at one of 26 oncology centers in the United Kingdom between April and October 2020.
Records on 1,117 patients were available for the initial analysis. The patients’ median age was 72 years (range, 38-93 years), and half were women.
The records showed changes to diagnostic investigations in 14% of patients (n = 160). Changes included not obtaining histology (4.6%, n = 51), not conducting nodal sampling (3.1%, n = 35), not performing pulmonary function tests (1.8%, n = 20), not conducting brain imaging (2.9%, n = 32), not performing PET/CT scans or having out-of-date scans (4.2%, n = 47), and delays in diagnosis (0.6%, n = 7).
Changes to treatment – deviations from standard care – occurred in 37% of patients (n = 415). This included 19% of patients (n = 210) having changes to radiotherapy dose or fractionation schedule, 8% (n = 86) undergoing radiotherapy instead of surgery, and 13% (n = 143) having their chemotherapy omitted or reduced.
The median number of radiotherapy fractions was 15 for patients who had their radiotherapy adjusted and 20 for those who had no treatment amendments.
“Those who had their treatment changed were more likely to have hypofractionated or ultra-hypofractionated radiotherapy,” Dr. Banfill said.
This was particularly true for patients with early-stage disease, she noted, where there was an increase in the percentage of patients getting more than 15 Gy per fraction. Even in stage III disease, there was an increased use of 3–5 Gy per fraction, although “virtually nobody” who had a change in treatment received less than 2 Gy per fraction, Dr. Banfill said.
“The changes are in line with what was reported in international recommendations,” observed Yolande Lievens, MD, PhD, of Ghent University Hospital in Belgium, who discussed the findings at the meeting.
Few patients had COVID-19
“It was striking to me to see that so few patients developed COVID-19 prior to radiotherapy or during radiotherapy,” Dr. Lievens noted. “This is actually something that we’ve also experienced in our setting.”
Indeed, just 15 patients (1%) were diagnosed with COVID-19, 10 of whom were diagnosed before receiving radiotherapy.
Dr. Banfill observed that the COVID-19 diagnosis had been “a reasonable time” before the patients started radiotherapy, and some had been diagnosed with lung cancer as a result of having a chest x-ray for suspected COVID-19.
Of the four patients who were diagnosed during treatment, two had their radiotherapy interrupted as a result.
The low COVID-19 rate is perhaps a result of the protective measures recommended in the United Kingdom, such as advising patients to shield from others, Dr. Banfill said.
Are changes to practice likely to hold?
“Part of the reason we actually stopped the data collection in October was that people were starting to go, ‘Well, is this actually a change?’ because they’d been doing it for 6 months,” Dr. Banfill observed during the discussion session.
“It was becoming almost normal for some of these hypofractionated changes. I think there is potential for these to become more embedded going forward,” she said. Data on how these changes might affect patients in the long term is going to be the focus of a future analysis.
“There is ongoing data collection on recurrence and survival and toxicity, which will hopefully provide more information on the outcomes of this patient group,” Dr. Banfill said.
The COVID-RT Lung project is supported by the NIHR Manchester Biomedical Research Centre. Dr. Banfill and Dr. Lievens reported no relevant conflicts of interest.

One U.K. guideline included recommendations on the use of hypofractionation in the COVID-19 era. The recommendations focused on altering the dosage or length of radiotherapy treatments to try to reduce the number of hospital visits, thereby reducing the risk of exposing patients to SARS-CoV-2.
“The aim of these guidelines is very much to reduce the risk to patients,” Dr. Banfill said. “These patients are often at higher risk of serious COVID-19, both as a result of their cancer and also as a result of many of the coexisting medical conditions that they have, such as COPD [chronic obstructive pulmonary disease],” she explained.
The COVID-RT Lung study was essentially born out of these guidelines. The goals of the study were to see what changes to radiotherapy practice occurred as a result of the guidelines and to assess how the changes have affected patient outcomes.
Changes to diagnosis and treatment
COVID-RT Lung is an ongoing, prospective study of patients with biopsy- or imaging-proven stage I–III lung cancer who were referred for, or treated with, radical radiotherapy at one of 26 oncology centers in the United Kingdom between April and October 2020.
Records on 1,117 patients were available for the initial analysis. The patients’ median age was 72 years (range, 38-93 years), and half were women.
The records showed changes to diagnostic investigations in 14% of patients (n = 160). Changes included not obtaining histology (4.6%, n = 51), not conducting nodal sampling (3.1%, n = 35), not performing pulmonary function tests (1.8%, n = 20), not conducting brain imaging (2.9%, n = 32), not performing PET/CT scans or having out-of-date scans (4.2%, n = 47), and delays in diagnosis (0.6%, n = 7).
Changes to treatment – deviations from standard care – occurred in 37% of patients (n = 415). This included 19% of patients (n = 210) having changes to radiotherapy dose or fractionation schedule, 8% (n = 86) undergoing radiotherapy instead of surgery, and 13% (n = 143) having their chemotherapy omitted or reduced.
The median number of radiotherapy fractions was 15 for patients who had their radiotherapy adjusted and 20 for those who had no treatment amendments.
“Those who had their treatment changed were more likely to have hypofractionated or ultra-hypofractionated radiotherapy,” Dr. Banfill said.
This was particularly true for patients with early-stage disease, she noted, where there was an increase in the percentage of patients getting more than 15 Gy per fraction. Even in stage III disease, there was an increased use of 3–5 Gy per fraction, although “virtually nobody” who had a change in treatment received less than 2 Gy per fraction, Dr. Banfill said.
“The changes are in line with what was reported in international recommendations,” observed Yolande Lievens, MD, PhD, of Ghent University Hospital in Belgium, who discussed the findings at the meeting.
Few patients had COVID-19
“It was striking to me to see that so few patients developed COVID-19 prior to radiotherapy or during radiotherapy,” Dr. Lievens noted. “This is actually something that we’ve also experienced in our setting.”
Indeed, just 15 patients (1%) were diagnosed with COVID-19, 10 of whom were diagnosed before receiving radiotherapy.
Dr. Banfill observed that the COVID-19 diagnosis had been “a reasonable time” before the patients started radiotherapy, and some had been diagnosed with lung cancer as a result of having a chest x-ray for suspected COVID-19.
Of the four patients who were diagnosed during treatment, two had their radiotherapy interrupted as a result.
The low COVID-19 rate is perhaps a result of the protective measures recommended in the United Kingdom, such as advising patients to shield from others, Dr. Banfill said.
Are changes to practice likely to hold?
“Part of the reason we actually stopped the data collection in October was that people were starting to go, ‘Well, is this actually a change?’ because they’d been doing it for 6 months,” Dr. Banfill observed during the discussion session.
“It was becoming almost normal for some of these hypofractionated changes. I think there is potential for these to become more embedded going forward,” she said. Data on how these changes might affect patients in the long term is going to be the focus of a future analysis.
“There is ongoing data collection on recurrence and survival and toxicity, which will hopefully provide more information on the outcomes of this patient group,” Dr. Banfill said.
The COVID-RT Lung project is supported by the NIHR Manchester Biomedical Research Centre. Dr. Banfill and Dr. Lievens reported no relevant conflicts of interest.
The U.K.-based study showed that patients with stage I-III lung cancer who were set to undergo radiotherapy with curative intent were more likely to receive fewer fractions at higher doses when treated between April and October 2020. During that period, 19% of patients had their radiotherapy dose or fractionation schedule changed to deviate from standard care.
In addition, 8% of patients who were set to undergo surgery ultimately received radiotherapy instead, presumably to ease pressures on already struggling intensive care services, said Kathryn Banfill, MBChB, of Christie NHS Foundation Trust in Manchester, England.
Dr. Banfill presented results from the COVID-RT Lung study at the European Lung Cancer Virtual Congress 2021 (Abstract 203MO).

Cardiovascular risks elevated in transgender youth
Cardiovascular and metabolic risk factors are increased among transgender youths, compared with youths who are not transgender. Elevations in lipid levels and body mass index (BMI) also occur in adult transgender patients, new research shows.
“This is the first study of its size in the United States of which we are aware that looks at the odds of youth with a diagnosis of gender dysphoria having medical diagnoses that relate to overall metabolic and cardiovascular health,” first author Anna Valentine, MD, of Children’s Hospital Colorado, Aurora, said in a press statement.
Although previous studies have shown that among transgender adults, BMI is higher and there is an increased risk for cardiovascular events, such as stroke or heart attack, compared with nontransgender people, research on adolescent transgender patients has been lacking.
With a recent survey showing that nearly 2% of adolescents identify as transgender, interest in health outcomes among younger patients is high.
To investigate, Dr. Valentine, and colleagues evaluated data from the PEDSnet pediatric database on 4,177 youths who had received a diagnosis of gender dysphoria. The participants had been enrolled at six sites from 2009 to 2019. The researchers compared these patients in a ratio of 1:4 with 16,664 control persons who had not been diagnosed with gender dysphoria. They reported their findings as a poster at the annual meeting of the Endocrine Society.
For the propensity-score analysis, participants were matched according to year of birth, age at last visit, site, race, ethnicity, insurance status, and duration in the database.
In both the transgender and control groups, about 66% were female at birth, 73% were White, and 9% Hispanic. For both groups, the average age was 16.2 years at the last visit. The average duration in the database was 7 years.
Study didn’t distinguish between those receiving and those not receiving gender-affirming hormones
In the retrospective study, among those who identified as transgender, the rates of diagnoses of dyslipidemia (odds ratio, 1.6; P < .0001) and metabolic syndrome (OR, 1.9; P = .0086) were significantly higher, compared with those without gender dysphoria.
Among the transgender male patients (born female) but not transgender female patients (born male), rates of diagnoses of overweight/obesity (OR, 1.7; P < .0001) and polycystic ovary syndrome were higher (OR, 1.9, P = .0006), compared with controls.
Gender-affirming hormone therapy, such as with testosterone or estradiol, is among the suspected culprits for the cardiovascular effects. However, importantly, this study did not differentiate between patients who had received estradiol or testosterone for gender affirmation and those who had not, Dr. Valentine said.
“We don’t know [whether gender-affirming hormone therapy is a cause], as we have not looked at this yet,” she said in an interview. “We are looking at that in our next analyses and will be including that in our future publication.
“We’ll also be looking at the relationship between having overweight/obesity and the other diagnoses that influence cardiovascular health (high blood pressure, liver dysfunction, and abnormal cholesterol), as that could certainly be playing a role as well,” she said.
For many transgender patients, gender-affirming hormone therapy is lifelong. One question that needs to be evaluated concerns whether the dose of such therapy has a role on cardiovascular effects and if so, whether adjustments could be made without compromising the therapeutic effect, Dr. Valentine noted.
“This is an important question, and future research is needed to evaluate whether doses [of gender-affirming hormones] are related to cardiometabolic outcomes,” she said.
Potential confounders in the study include the fact that rates of overweight and obesity are higher among youths with gender dysphoria. This can in itself can increase the risk for other disorders, Dr. Valentine noted.
Furthermore, rates of mental health comorbidities are higher among youths with gender dysphoria. One consequence of this may be that they engage in less physical activity, she said.
Hormone therapy, health care disparities, or both could explain risk
In commenting on the study, Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery, the Mount Sinai Health System, New York, said that although similar cardiovascular effects are known to occur in transgender adults as well, they may or may not be hormone related. Other factors can increase the risk.
“With transgender adults, any differences in lipids or cardiac risk factors relative to cisgender people might be attributable either to hormone therapy or to health care disparities,” he said in an interview.
“The data are mixed. It may be that most differences relate to lack of access to care and to mistreatment by society,” he said. “Even studies that focus on hormones see a worsened situation for trans women versus trans men.”
Other recent research that shows potential cardiovascular effects among adult transgender men includes a study of more than 1,000 transgender men (born female) who received testosterone. That study, which was also presented at the ENDO meeting and was reported by this news organization, found an increased risk for high hematocrit levels, which could lead to a thrombotic event.
However, a study published in Pediatrics, which was also reported by this news organization, that included 611 transgender youths who had taken gender-affirming hormone therapy for more than a year found no increased risk for thrombosis, even in the presence of thrombosis risk factors, including obesity, tobacco use, and family history of thrombosis. However, the senior author of that study pointed out that the duration of follow-up in that study was relatively short, which may have been why they did not find an increased risk for thrombosis.
Dr. Safer noted that transgender youths and adults alike face a host of cultural factors that could play a role in increased cardiovascular risks.
“For adults, the major candidate explanations for worse BMI and cardiac risk factors are societal mistreatment, and for trans women specifically, progestins. For youth, the major candidate explanations are societal mistreatment and lack of access to athletics,” he said.
The authors and Dr. Safer disclosed no relevant financial relationships.

Hyperphagia, anxiety eased with carbetocin in patients with Prader-Willi syndrome
Children and adolescents with Prader-Willi syndrome (PWS) who received three daily, intranasal doses of carbetocin, an investigational, long-acting oxytocin analogue, had significant improvement in hyperphagia and anxiety during 8 weeks on treatment, compared with placebo in a multicenter, phase 3 trial with 119 patients.
The treatment also appeared safe during up to 56 additional weeks on active treatment, with no serious adverse effects nor “unexpected” events, and once completing the study about 95% of enrolled patients opted to remain on active treatment, Cheri L. Deal, MD, PhD, said at the annual meeting of the Endocrine Society.
Based on “the significant results for the placebo-controlled period, as well as for those finishing the 56-week extension, we may well have a new armament for helping these kids and their families deal with the unrelenting hunger of patients with PWS as well as some of the behavioral symptoms,” Dr. Deal, chief of endocrinology and diabetes at the Sainte-Justine Mother-Child University of Montreal Hospital, said in an interview. No treatment currently has labeling for addressing the hyperphagia or anxiety that is characteristic and often problematic for children and adolescents with PWS, an autosomal dominant genetic disease with an incidence of about 1 in 15,000 births and an estimated U.S. prevalence of about 9,000 cases, or about 1 case for every 37,000 people.
‘Gorgeous’ safety
“The results looked pretty positive, and we’re encouraged by what appears to be a good safety profile, so overall I think the PWS community is very excited by the results and is very interested in getting access to this drug,” commented Theresa V. Strong, PhD, director of research programs for the Foundation for Prader-Willi Research in Walnut, Calif., a group not involved with the study. Currently, “we have no effective treatments for these difficult behaviors” of hyperphagia and anxiety. Surveys and studies run by the foundation have documented that hyperphagia and anxiety “were the two most important symptoms that families would like to see treated,” Dr. Strong added in an interview.
PWS “is complex and affects almost every aspect of the lives of affected people and their families. Any treatment that can chip away at some of the problems these patients have can be a huge benefit to the patients and their families,” said Jennifer L. Miller, MD, a professor of pediatric endocrinology at the University of Florida, Gainesville, and a coinvestigator on the study.
But the finding that carbetocin appeared to address, at least in part, this unmet need while compiling a safety record that Dr. Miller called “gorgeous” and “remarkable,” also came with a few limitations.
Fewer patients than planned, and muddled outcomes
The CARE-PWS trial aimed to enroll 175 patients, but fell short once the COVID-19 pandemic hit. Plus the trial had two prespecified primary endpoints – improvements in a measure of hyperphagia, and in a measure of obsessive and compulsive behaviors – specifically in the 40 patients who received the higher of the two dosages studied, 9.6 mg t.i.d. intranasally. Neither endpoint showed significant improvement among the patients on this dosage, compared with the 40 patients who received placebo, although both outcomes trended in the right direction in the actively treated patients.
The study’s positive results came in a secondary treatment group, 39 patients who received 3.2 mg t.i.d., also intranasally. This subgroup had significant benefit, compared with placebo, for reducing hyperphagia symptoms as measured on the Hyperphagia Questionnaire for Clinical Trials (HQ-CT) Total Score. After the first 8 weeks on treatment, patients on the lower carbetocin dosage had an average reduction in their HQ-CT score of greater than 5 points, more than double the reduction seen among control patients who received placebo.
Those on the 3.2-mg t.i.d. dosage also showed significant improvements, compared with placebo, for anxiety, measured by the PWS Anxiety and Distress Questionnaire Total Score, as well as on measures of clinical global impression of severity, and of clinical global impression of change. Like the higher-dosage patients the lower-dosage subgroup did not show a significant difference compared with placebo for the other primary endpoint, change in obsessive and compulsive behaviors as measured by the Children’s Yale-Brown Obsessive-Compulsive Scale Total Score, although also like the higher dosage the effect from the lower dosage trended toward benefit.
A further limitation was that, at the time of her report, presented in abstract OR16-3 at the meeting, Dr. Deal could only present complete 64-week follow-up for 72 patients, although this reassuringly showed that, as time on the 9.6-mg t.i.d. dosage continued beyond 8 weeks, patients gradually improved their HQ-CT response so that by 64 weeks on treatment their hyperphagia score had improved as much as in the patients who received the lower dosage.
In short, documented benefits occurred on the lower dosage, especially for clinically meaningful symptoms like hyperphagia and anxiety, but the study’s overall results were not fully consistent by statistical criteria.
Benefiting an unmet need?
“While it is regrettable that we did not get to 175 patients because of COVID-19, the dataset is significant enough for me to feel that the FDA [Food and Drug Administration] needs to take a very serious look and consider approval,” Dr. Deal said in an interview. “Once safety is assured, which I think it is, I can only hope that regulatory officials understand their unmet needs of this rare disease community and will allow the drug to move to the next stage.”
“This is a very rare disease, and having families participate in trials is really challenging,” especially while the COVID-19 pandemic continues, Dr. Strong said. For the pediatric and adolescent patients targeted in this study “it will take a while for COVID to go away and for families to feel safe again being in a trial, so a real concern is that a need for more clinical trials is not terribly feasible now. Given that the safety profile looked good and one dose seemed to have good efficacy, as long as the long-term data continue to look good we’d love for the FDA to look at the existing data and see whether there is a path forward.”
Dr. Miller highlighted the limitations of what the CARE-PWS findings show.
“Given that it was only an 8-week trial of drug against placebo, and the fact that the primary outcomes weren’t met for the higher dose, my thought is that potentially we need to study more patients for a longer period at the 3.2-mg dose,” she said. She acknowledged that the metric used in the study to assess obsessive and compulsive behaviors is “very difficult” to apply to patients with PWS because of uncertainties in scoring obsessions in patients “who are not very good at telling you what they’re thinking.” Plus, “it’s absolutely not a problem that we did not see an effect on obsession and compulsions if the treatment potentially improves anxiety and hyperphagia, which are very common.” A treatment that reliably reduces these symptoms “would be amazing,” Dr. Miller added.
“PWS is very rare, so it’s very hard to do trials. Maybe the FDA will approve carbetocin because it was safe and gave a signal of efficacy at the lower dose. But my thought is that additional treatment trials are needed with only the lower dose and with longer duration,” she said.
CARE-PWS enrolled patients with nutritional phase 3 PWS who were aged 7-18 years at any of 24 sites in the United States, Canada, or Australia during 2018-2020. They averaged about 12 years of age, and 56% were girls.
The most common adverse effect from carbetocin was flushing, occurring in 14% of those on the lower dose and 21% on the higher dose, but not in any placebo patient. Other adverse effects more common on the lower dose than in the placebo group included headache in 16%, and diarrhea in 9%.
Carbetocin is not only long-lasting in circulation, it also has better affinity for oxytocin receptors than for vasopressin receptors, reducing the potential for causing hyponatremia. The idea to use it in patients with PWS followed prior studies with oxytocin, which had shown dopamine interactions that reduced anxiety and influenced food ingestion behavior. Brain autopsy studies had shown that patients with Prader-Willi syndrome have substantially fewer neurons than usual producing oxytocin. Treatment with intranasal carbetocin had shown efficacy for improving hyperphagia and behavior in a controlled phase 2 study with 37 patients.
Carbetocin is approved for use in reducing excessive bleeding after childbirth, particularly cesarean, in more than 20 countries outside the United States.
CARE-PWS was sponsored by Levo Therapeutics, the company developing carbetocin. Dr. Deal has been an adviser to Levo Therapeutics. Dr. Strong is an employee of the Foundation for Prader-Willi Research, which has received support from Levo Therapeutics as well as from other drug companies, but which receives most of its funding from individuals. Dr. Miller has received research funding from Levo Therapeutics and also from Harmony Biosciences, Rhythm Pharmaceuticals, and Soleno Therapeutics.
Children and adolescents with Prader-Willi syndrome (PWS) who received three daily, intranasal doses of carbetocin, an investigational, long-acting oxytocin analogue, had significant improvement in hyperphagia and anxiety during 8 weeks on treatment, compared with placebo in a multicenter, phase 3 trial with 119 patients.
The treatment also appeared safe during up to 56 additional weeks on active treatment, with no serious adverse effects nor “unexpected” events, and once completing the study about 95% of enrolled patients opted to remain on active treatment, Cheri L. Deal, MD, PhD, said at the annual meeting of the Endocrine Society.
Based on “the significant results for the placebo-controlled period, as well as for those finishing the 56-week extension, we may well have a new armament for helping these kids and their families deal with the unrelenting hunger of patients with PWS as well as some of the behavioral symptoms,” Dr. Deal, chief of endocrinology and diabetes at the Sainte-Justine Mother-Child University of Montreal Hospital, said in an interview. No treatment currently has labeling for addressing the hyperphagia or anxiety that is characteristic and often problematic for children and adolescents with PWS, an autosomal dominant genetic disease with an incidence of about 1 in 15,000 births and an estimated U.S. prevalence of about 9,000 cases, or about 1 case for every 37,000 people.
‘Gorgeous’ safety
“The results looked pretty positive, and we’re encouraged by what appears to be a good safety profile, so overall I think the PWS community is very excited by the results and is very interested in getting access to this drug,” commented Theresa V. Strong, PhD, director of research programs for the Foundation for Prader-Willi Research in Walnut, Calif., a group not involved with the study. Currently, “we have no effective treatments for these difficult behaviors” of hyperphagia and anxiety. Surveys and studies run by the foundation have documented that hyperphagia and anxiety “were the two most important symptoms that families would like to see treated,” Dr. Strong added in an interview.
PWS “is complex and affects almost every aspect of the lives of affected people and their families. Any treatment that can chip away at some of the problems these patients have can be a huge benefit to the patients and their families,” said Jennifer L. Miller, MD, a professor of pediatric endocrinology at the University of Florida, Gainesville, and a coinvestigator on the study.
But the finding that carbetocin appeared to address, at least in part, this unmet need while compiling a safety record that Dr. Miller called “gorgeous” and “remarkable,” also came with a few limitations.
Fewer patients than planned, and muddled outcomes
The CARE-PWS trial aimed to enroll 175 patients, but fell short once the COVID-19 pandemic hit. Plus the trial had two prespecified primary endpoints – improvements in a measure of hyperphagia, and in a measure of obsessive and compulsive behaviors – specifically in the 40 patients who received the higher of the two dosages studied, 9.6 mg t.i.d. intranasally. Neither endpoint showed significant improvement among the patients on this dosage, compared with the 40 patients who received placebo, although both outcomes trended in the right direction in the actively treated patients.
The study’s positive results came in a secondary treatment group, 39 patients who received 3.2 mg t.i.d., also intranasally. This subgroup had significant benefit, compared with placebo, for reducing hyperphagia symptoms as measured on the Hyperphagia Questionnaire for Clinical Trials (HQ-CT) Total Score. After the first 8 weeks on treatment, patients on the lower carbetocin dosage had an average reduction in their HQ-CT score of greater than 5 points, more than double the reduction seen among control patients who received placebo.
Those on the 3.2-mg t.i.d. dosage also showed significant improvements, compared with placebo, for anxiety, measured by the PWS Anxiety and Distress Questionnaire Total Score, as well as on measures of clinical global impression of severity, and of clinical global impression of change. Like the higher-dosage patients the lower-dosage subgroup did not show a significant difference compared with placebo for the other primary endpoint, change in obsessive and compulsive behaviors as measured by the Children’s Yale-Brown Obsessive-Compulsive Scale Total Score, although also like the higher dosage the effect from the lower dosage trended toward benefit.
A further limitation was that, at the time of her report, presented in abstract OR16-3 at the meeting, Dr. Deal could only present complete 64-week follow-up for 72 patients, although this reassuringly showed that, as time on the 9.6-mg t.i.d. dosage continued beyond 8 weeks, patients gradually improved their HQ-CT response so that by 64 weeks on treatment their hyperphagia score had improved as much as in the patients who received the lower dosage.
In short, documented benefits occurred on the lower dosage, especially for clinically meaningful symptoms like hyperphagia and anxiety, but the study’s overall results were not fully consistent by statistical criteria.
Benefiting an unmet need?
“While it is regrettable that we did not get to 175 patients because of COVID-19, the dataset is significant enough for me to feel that the FDA [Food and Drug Administration] needs to take a very serious look and consider approval,” Dr. Deal said in an interview. “Once safety is assured, which I think it is, I can only hope that regulatory officials understand their unmet needs of this rare disease community and will allow the drug to move to the next stage.”
“This is a very rare disease, and having families participate in trials is really challenging,” especially while the COVID-19 pandemic continues, Dr. Strong said. For the pediatric and adolescent patients targeted in this study “it will take a while for COVID to go away and for families to feel safe again being in a trial, so a real concern is that a need for more clinical trials is not terribly feasible now. Given that the safety profile looked good and one dose seemed to have good efficacy, as long as the long-term data continue to look good we’d love for the FDA to look at the existing data and see whether there is a path forward.”

Bimekizumab superior to adalimumab in head-to-head psoriasis study
for treatment of moderate to severe plaque psoriasis in the head-to-head, phase 3 BE SURE trial, Jerry Bagel, MD, said at Innovations in Dermatology: Virtual Spring Conference 2021.
“Results demonstrated that bimekizumab was superior to adalimumab over 16 weeks of treatment in terms of the speed, depth, and durability of skin clearance,” reported Dr. Bagel, a dermatologist at the Psoriasis Center of Central New Jersey, East Windsor.
The Food and Drug Administration is now reviewing UCB’s application for marketing approval of bimekizumab for treatment of moderate to severe psoriasis in adults.
BE SURE was a 478-patient, double-blind, phase 3 trial in which patients were randomized to one of three regimens: 320 mg of bimekizumab every 4 weeks; the tumor necrosis factor blocker adalimumab (Humira) at 40 mg every 2 weeks for 24 weeks, followed by a switch to bimekizumab at 320 mg every 4 weeks; or 320 mg of bimekizumab every 4 weeks for 16 weeks, then ratcheting back to dosing every 8 weeks. The trial concluded at week 56, Dr. Bagel explained at the conference sponsored by MedscapeLIVE! and the producers of the Hawaii Dermatology Seminar and Caribbean Dermatology Symposium.
The two coprimary endpoints were the 16-week rates of a 90% improvement from baseline in Psoriasis Area and Severity Index score, or PASI 90 response, and an Investigator’s Global Assessment (IGA) score of 0 or 1, meaning clear or almost clear. Bimekizumab every 4 weeks bested adalimumab on both endpoints, with a PASI 90 rate of 86.2%, compared with 47.2%, and a IGA 0/1 rate of 85.3% versus 57.2%. The 16-week PASI 100 response rate was 60.8% with bimekizumab and 23.9% with adalimumab.
The response to bimekizumab was notably fast: already by week 4, the PASI 75 rate was 76.4%, compared with 31.4% with adalimumab. And once patients switched from adalimumab to bimekizumab at week 24, their response rates shot up rapidly. Bimekizumab was equally effective whether dosed at 320 mg every 4 weeks or at maintenance dosing every 8 weeks, such that at week 56 patients in all three study arms had PASI 90 rates of 82%-84%.
The most frequent treatment-emergent adverse events associated with bimekizumab were oral candidiasis, nasopharyngitis, and upper respiratory tract infection. The oral candidiasis, which occurred in 13.2% of patients on bimekizumab every 4 weeks, was mainly mild to moderate, localized, and in no instance led to discontinuation of therapy, according to Dr. Bagel.
“Very impressive data,” commented session comoderator Linda Stein Gold, MD. “This study shows some data that’s potentially unprecedented. Bimekizumab was superior to one of the drugs that we know, we’ve used, and know is very, very effective.”
“Note the speed of this drug,” added comoderator Bruce E. Strober, MD, PhD, of Yale University, New Haven, Conn., and Central Connecticut Dermatology, Cromwell, Conn. “It achieved at week 4 the efficacy that it took adalimumab until week 16 to reach. So it is a very fast drug. Bimekizumab will be the fastest drug you’ve ever, ever worked with.”
“You’ll see in the bimekizumab studies about a fivefold increased frequency of oral candidiasis relative to our more legacy IL-17 inhibitors, such as ixekizumab, secukinumab, and brodalumab. I think that means approximately one in five or one in six patients will have some form of candidiasis when you treat them with bimekizumab,” he said. Therefore, he added, “in some patients you’ll have to manage oral candidiasis. Most affected patients don’t leave the studies, so it’s manageable, but you’ll have to become something of an authority on how to treat with, for example, oral antifungal swish-and-swallow, swish-and-spit, or oral fluconazole. And some of these patients will have recurrent infections.”
It’s a prospect that doesn’t concern Dr. Stein Gold. “This is a side effect that we can treat. We can see it, we’re comfortable with it, and it’s certainly something we can get a handle on,” said Dr. Stein Gold, director of dermatology clinical research at the Henry Ford Health System in Detroit.
BE SURE was funded by UCB. Dr. Bagel reported serving as a speaker for, consultant to, and paid investigator for AbbVie, Celgene, Eli Lilly, Leo Pharma, Novartis, and Ortho Pharmaceuticals. Dr. Stein Gold and Dr. Strober reported having financial relationships with numerous pharmaceutical companies.

Most affected patients don’t leave the studies, so it’s manageable, but you’ll have to become something of an authority on how to treat with, for example, oral antifungal swish-and-swallow, swish-and-spit, or oral fluconazole. And some of these patients will have recurrent infections.”
It’s a prospect that doesn’t concern Dr. Stein Gold. “This is a side effect that we can treat. We can see it, we’re comfortable with it, and it’s certainly something we can get a handle on,” said Dr. Stein Gold, director of dermatology clinical research at the Henry Ford Health System in Detroit.
BE SURE was funded by UCB. Dr. Bagel reported serving as a speaker for, consultant to, and paid investigator for AbbVie, Celgene, Eli Lilly, Leo Pharma, Novartis, and Ortho Pharmaceuticals. Dr. Stein Gold and Dr. Strober reported having financial relationships with numerous pharmaceutical companies.

Hedgehog inhibitor alternative dosing advantageous for BCC
in a successful effort to maintain efficacy while reducing treatment discontinuation caused by unacceptable side effects, Vishal Patel, MD, said at Innovations in Dermatology: Virtual Spring Conference 2021.
“It’s the tolerability issues that make these drugs very difficult to prescribe and use regularly. What we’ve seen in the last few years is that a lot of alternative dosing regimens have been published that have been both effective at treating the tumor and keeping the tumor clear and at bay while lowering the side-effect profile,” explained Dr. Patel, a Mohs surgeon and director of the cutaneous oncology program at the George Washington University Cancer Center in Washington, D.C.
Product labeling for the two available hedgehog pathway inhibitors, vismodegib (Erivedge) and sonidegib (Odomzo), calls for once-daily therapy until disease progression or unacceptable toxicity. Studies show that, when used in this way, these agents achieve objective response rates in the 40% range for patients with locally advanced BCC and 15%-33% for those with metastatic BCC.
“The critical thing in these patients is not that the drugs work – although they can work in quite remarkable ways – but rather it’s that nearly all patients experience at least one side effect. And grade 3 or 4 adverse effects that can lead to cessation of drug occur in about 25% of patients,” he said at the conference sponsored by MedscapeLIVE! and the producers of the Hawaii Dermatology Seminar and Caribbean Dermatology Symposium.
The classic side effects of the hedgehog pathway inhibitors are muscle spasms, hair loss, fatigue, loss of taste, diarrhea, and weight loss.
Among the alternative dosing regimens that have been published with good results, mostly in single-center retrospective case series, are a weekdays-on/weekends-off strategy at the Cleveland Clinic and an Italian approach entailing an initial 3-4 months of daily therapy followed by a switch to alternate-day therapy.
But Dr. Patel favors a different off-label regimen in lieu of Food and Drug Administration–recommended daily dosing indefinitely. It takes advantage of the fact that most patients don’t begin to get the classic side effects until about the 3-month mark.
“What we’ve begun to recommend as a much better option for patients who need to be on the drug potentially forever is that the drug is dosed daily for 3 months to shrink the tumor and get the optimal effect, and then at that point we taper the dose down to every other day, then every third day, or even up to a week as long as the tumor continues to stay at bay. If there’s any sign of recurrence or a scouting biopsy shows tumor, we reinstitute the daily medicine,” the dermatologist said.
This strategy requires careful monitoring for emergence of the typical side effects. Also, an important caveat regarding sonidegib is that it shouldn’t be given concomitantly with medications that are moderate or strong inhibitors of CYP3A, so it’s essential to get a complete medical history when giving this drug, Dr. Patel noted.
He reported having no financial conflicts regarding his presentation.
