Ropinirole, a drug used for Parkinson’s disease (PD), shows promise in slowing the progression of amyotrophic lateral sclerosis (ALS), early research suggests. However, at least one expert believes the study has “significant flaws.”
 

Investigators randomly assigned 20 individuals with sporadic ALS to receive either ropinirole or placebo for 24 weeks. During the double-blind period, there was no difference between the groups in terms of decline in functional status.

However, during a further open-label extension period, the ropinirole group showed significant suppression of functional decline and an average of an additional 7 months of progression-free survival.

The researchers were able to predict clinical responsiveness to ropinirole in vitro by analyzing motor neurons derived from participants’ stem cells.

“We found that ropinirole is safe and tolerable for ALS patients and shows therapeutic promise at helping them sustain daily activity and muscle strength,” first author Satoru Morimoto, MD, of the department of physiology, Keio University School of Medicine, Tokyo, said in a news release.

The study was published online in Cell Stem Cell.
 

Feasibility study

“ALS is totally incurable and it’s a very difficult disease to treat,” senior author Hideyuki Okano, MD, PhD, professor, department of physiology, Keio University, said in the news release.

Preclinical animal models have “limited translational potential” for identifying drug candidates, but induced pluripotent stem cell (iPSC)–derived motor neurons (MNs) from ALS patients can “overcome these limitations for drug screening,” the authors write.

“We previously identified ropinirole [a dopamine D2 receptor agonist] as a potential anti-ALS drug in vitro by iPSC drug discovery,” Dr. Okano said.

The current trial was a randomized, placebo-controlled phase 1/2a feasibility trial that evaluated the safety, tolerability, and efficacy of ropinirole in patients with ALS, using several parameters:

• The revised ALS functional rating scale (ALSFRS-R) score.
• Composite functional endpoints.
• Event-free survival.
• Time to ≤ 50% forced vital capacity (FVC).

The trial consisted of a 12-week run-in period, a 24-week double-blind period, an open-label extension period that lasted from 4 to 24 weeks, and a 4-week follow-up period after administration.

Thirteen patients were assigned to receive ropinirole (23.1% women; mean age, 65.2 ± 12.6 years; 7.7% with clinically definite and 76.9% with clinically probable ALS); seven were assigned to receive placebo (57.1% women; mean age, 66.3 ± 7.5 years; 14.3% with clinically definite and 85.7% with clinically probable ALS).

Of the treatment group, 30.8% had a bulbar onset lesion vs. 57.1% in the placebo group. At baseline, the mean FVC was 94.4% ± 14.9 and 81.5% ± 23.2 in the ropinirole and placebo groups, respectively. The mean body mass index (BMI) was 22.91 ± 3.82 and 19.69 ± 2.63, respectively.

Of the participants,12 in the ropinirole and six in the control group completed the full 24-week treatment protocol; 12 in the ropinirole and five in the placebo group completed the open-label extension (participants who had received placebo were switched to the active drug).

However only seven participants in the ropinirole group and one participant in the placebo group completed the full 1-year trial.
 

‘Striking correlation’

“During the double-blind period, muscle strength and daily activity were maintained, but a decline in the ALSFRS-R … was not different from that in the placebo group,” the researchers write.

In the open-label extension period, the ropinirole group showed “significant suppression of ALSFRS-R decline,” with an ALSFRS-R score change of only 7.75 (95% confidence interval, 10.66-4.63) for the treatment group vs. 17.51 (95% CI, 22.46-12.56) for the placebo group.

The researchers used the assessment of function and survival (CAFS) score, which adjusts the ALSFRS-R score against mortality, to see whether functional benefits translated into improved survival.

The score “favored ropinirole” in the open-extension period and the entire treatment period but not in the double-blind period.

Significant flaws

Commenting for this article, Carmel Armon, MD, MHS, professor of neurology, Loma Linda (Calif.) University, said the study “falls short of being a credible 1/2a clinical trial.”

Although the “intentions were good and the design not unusual,” the two groups were not “balanced on risk factors for faster progressing disease.” Rather, the placebo group was “tilted towards faster progressing disease” because there were more clinically definite and probable ALS patients in the placebo group than the treatment group, and there were more patients with bulbar onset.

Participants in the placebo group also had shorter median disease duration, lower BMI, and lower FVC, noted Dr. Armon, who was not involved with the study.

And only 1 in 7 control patients completed the open-label extension, compared with 7 of 13 patients in the intervention group.

“With these limitations, I would be disinclined to rely on the findings to justify a larger clinical trial,” Dr. Armon concluded.

The trial was sponsored by K Pharma. The study drug, active drugs, and placebo were supplied free of charge by GlaxoSmithKline K.K. Dr. Okano received grants from JSPS and AMED and grants and personal fees from K Pharma during the conduct of the study and personal fees from Sanbio, outside the submitted work. Dr. Okano has a patent on a therapeutic agent for ALS and composition for treatment licensed to K Pharma. The other authors’ disclosures and additional information are available in the original article. Dr. Armon reports no relevant financial relationships.

TOPLINE:

Girls born with congenital diaphragmatic hernia (CDH), a rare birth defect that affects approximately one in 3,600 babies in the United States, are slightly less likely to survive than their male counterparts with the condition, a study published in the Journal of Pediatrics has found.

METHODOLOGY:

• The retrospective cohort study used demographic, clinical, and outcomes data from the  registry to investigate the role of biological sex for babies with CDH.
• The study included more than 7,200 newborns at 105 hospitals across 17 countries from January 2007 to December 2018.
• The primary outcomes were 30-day, 60-day, and in-hospital mortality.
• The secondary outcomes included weight gain during admission, feeding, and oxygen status at 30 days and at discharge.

TAKEAWAY:

• After controlling for markers of disease severity, girls with CDH had a 32% increased risk for death at 30-days (adjusted hazard ratio, 1.32; P = .02).
• Girls had lower survival rates at 30 days (77.3%), compared with boys (80.1%).
• The disparity remained at 60 days, with the survival rate for girls with CDH (73.5%) modestly lower than that for boys (77.2%), and also at discharge – 70.2%, compared with 74.2%, respectively.
• The survival differences between boys and girls primarily affected babies who did not undergo  cannulation; in this group, the survival rate for girls was 77.5%, compared with 82.1% for boys.
• Girls with CDH weighed less at birth (2.8 kg) than boys with the condition (3 kg); birth weight is a  for babies with CDH, .

IN PRACTICE:

“Although racial and ethnic outcome disparities have been documented in CDH, disparities between males and females are not well known,” Shaun Kunisaki, MD, MSc, a senior author of the study and professor of surgery at Johns Hopkins University in Baltimore, said in a press release about the findings. “It is really important to understand if those disparities exist, because it may change how we can better manage these patients.”

STUDY DETAILS:

The authors include seven from the division of general pediatric surgery and the division of pediatric respiratory sciences at Johns Hopkins University. Two authors are from the department of pediatric surgery at the University of Texas and Children’s Memorial Hermann Hospital, both in Houston.

LIMITATIONS:

The authors point to potential challenges with data collection, including diagnosis miscoding and missing data. They acknowledge that MRI fetal lung volumes, degree of liver herniation, and emerging markers of socioeconomic status were not available in the database. The study also could not examine long-term outcomes because data were limited to in-hospital variables.

DISCLOSURES:

The authors report no financial conflicts of interest.

Systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still’s disease (AOSD) should be grouped into one disease, Still’s disease, according to new diagnosis and treatment recommendations presented at the annual European Congress of Rheumatology.

The recommendations, made in collaboration with EULAR and the Pediatric Rheumatology European Society, emphasized that the ultimate treatment target for Still’s disease should be drug-free remission in all patients and that macrophage activation syndrome (MAS) should be identified and treated as soon as possible.

The task force focused on MAS because despite effective, innovative therapies, “we continued to see MAS,” said presenter Bruno Fautrel, MD, Pitié-Salpêtrière University Hospital, Paris. “We have to be very concerned about this potential complication.”

Dr. Fautrel copresented the recommendations with Fabrizio De Benedetti, MD, PhD, head of the division of rheumatology, Bambino Gesù Hospital, Rome.
 

Diagnosis

Dr. Fautrel noted that the cutoff age of 16 that differentiates sJIA and AOSD is “arbitrary.” There are some differences in age: The frequency of the disease is higher in young children, but it plateaus in young adults. Children under 18 months old are also far more likely to develop MAS.

To diagnose and treat Still’s disease, the recommendations state that clinicians should consider four criteria:

• A fever spiking at or above 39° C (102.2° F) for at least 7 days.
• A transient rash, preferentially on the trunk, that coincides with fever spikes, rash is typically erythematous but other rashes, like urticaria, can be consistent with the diagnosis.
• Some musculoskeletal involvement is common, involving arthralgia/myalgia.
• High levels of inflammation identified by neutrophilic leukocytosis, increased serum C-reactive protein (CRP), and ferritin.

Dr. Fautrel noted that, while arthritis can be present, it is not necessary to make a diagnosis. In pediatrics, “arthritis is likely to happen after a few weeks of the evolution of the disease,” and waiting for arthritis to develop can lead to diagnostic delay, “which is a problem.”

For individuals with suspected Still’s disease, NSAIDs can be used as a “bridging therapy” before the diagnosis is confirmed.
 

Treatment

The recommendations emphasized that treatment and therapeutic strategy “should be based on shared decision-making between the parents/patients and the treating team,” with the ultimate goal of drug-free remission.

To achieve this goal, the document outlines time-based targets for clinically inactive disease (CID). At 4 weeks, patients should have no fever, reduction of active or swollen joint count by more than 50%, a normal CRP level, and a rating of less than 20 on a visual analog scale of 0-100. At 3 months, patients should maintain clinically inactive disease with a glucocorticoid dose of less than 0.1 or 0.2 mg/kg per day. At 6 months, CID should be maintained without glucocorticoids.

While the authors of the recommendations noted that glucocorticoids are efficacious, their long-term use should be avoided because of safety issues. An interleukin-1 or IL-6 inhibitor should be prioritized and initiated as soon as possible after diagnosis.

Patients should maintain CID between 3 and 6 months before tapering off biologics.

The recommendations are congruent with the 2021 American College of Rheumatology’s guidelines for sJIA, noted Karen Onel, MD, pediatric rheumatologist, Hospital for Special Surgery, New York, and the principle investigator for the ACR guidelines. One main difference is that the EULAR recommendations included time lines for treatment targets, while the ACR’s did not.

“It’s great to have these time lines in there,” she said in an interview, though there are still some unknowns. “We don’t actually know what the tapering frequency should be,” she said, “but these are definitely goals that we need to explore and see how they evolve.”
 

MAS and lung complications

The EULAR recommendations also touched on two concerning complications, particularly in children: MAS and lung disease. According to the document, MAS should be considered in patients with Still’s disease with these symptoms: fever, splenomegaly, elevated serum ferritin, low cell counts, abnormal liver function tests, elevated serum triglycerides, and intravascular activation of coagulation. The MAS 2016 criteria can also be used to facilitate diagnosis.

“MAS treatment must include high-dose glucocorticoids,” the document states. “In addition, treatments including anakinra, ciclosporin, and/or interferon-gamma inhibitors should be considered as a part of initial therapy.”

The recommendations also addressed the risk for lung disease, “which is an emerging issue, particularly in children, that the physician should be very well aware of,” Dr. De Benedetti said. This complication can arise at any time point of the disease, he added.

The document advised actively screening for lung disease by searching for clinical symptoms such as digital clubbing, persistent cough, and shortness of breath. Pulmonary function tests like pulse oximetry and diffusing capacity of the lungs for carbon monoxide may also be used, but these standard lung function tests are very difficult to do in children under 6 years old, Dr. De Benedetti noted. The recommendations advise performing high-resolution CT in “any patients with clinical concerns.”

“We have lowered the threshold for CT scan because of the emerging features of this lung disease that may actually be lethal and therefore require prompt attention,” Dr. De Benedetti noted.

The recommendations for lung disease are “broad,” as there is still much to learn about the risk for lung disease in a small portion of sJIA patients, Dr. Onel said.

“There’s a lot that we are trying to work out about this; exactly how to screen, who to screen, what to do, who to treat, and how to treat really remains unclear,” she said. “We absolutely agree that this is a major, major issue that we need to come to some sort of agreement upon, but we’re just not there yet.”

Dr. De Benedetti, Dr. Fautrel, and Dr. Onel disclosed no relevant financial relationships.

• High levels of inflammation identified by neutrophilic leukocytosis, increased serum C-reactive protein (CRP), and ferritin.

Dr. Fautrel noted that, while arthritis can be present, it is not necessary to make a diagnosis. In pediatrics, “arthritis is likely to happen after a few weeks of the evolution of the disease,” and waiting for arthritis to develop can lead to diagnostic delay, “which is a problem.”

For individuals with suspected Still’s disease, NSAIDs can be used as a “bridging therapy” before the diagnosis is confirmed.
 

Treatment

The recommendations emphasized that treatment and therapeutic strategy “should be based on shared decision-making between the parents/patients and the treating team,” with the ultimate goal of drug-free remission.

To achieve this goal, the document outlines time-based targets for clinically inactive disease (CID). At 4 weeks, patients should have no fever, reduction of active or swollen joint count by more than 50%, a normal CRP level, and a rating of less than 20 on a visual analog scale of 0-100. At 3 months, patients should maintain clinically inactive disease with a glucocorticoid dose of less than 0.1 or 0.2 mg/kg per day. At 6 months, CID should be maintained without glucocorticoids.

While the authors of the recommendations noted that glucocorticoids are efficacious, their long-term use should be avoided because of safety issues. An interleukin-1 or IL-6 inhibitor should be prioritized and initiated as soon as possible after diagnosis.

Patients should maintain CID between 3 and 6 months before tapering off biologics.

The recommendations are congruent with the 2021 American College of Rheumatology’s guidelines for sJIA, noted Karen Onel, MD, pediatric rheumatologist, Hospital for Special Surgery, New York, and the principle investigator for the ACR guidelines. One main difference is that the EULAR recommendations included time lines for treatment targets, while the ACR’s did not.

“It’s great to have these time lines in there,” she said in an interview, though there are still some unknowns. “We don’t actually know what the tapering frequency should be,” she said, “but these are definitely goals that we need to explore and see how they evolve.”
 

MAS and lung complications

The EULAR recommendations also touched on two concerning complications, particularly in children: MAS and lung disease. According to the document, MAS should be considered in patients with Still’s disease with these symptoms: fever, splenomegaly, elevated serum ferritin, low cell counts, abnormal liver function tests, elevated serum triglycerides, and intravascular activation of coagulation. The MAS 2016 criteria can also be used to facilitate diagnosis.

“MAS treatment must include high-dose glucocorticoids,” the document states. “In addition, treatments including anakinra, ciclosporin, and/or interferon-gamma inhibitors should be considered as a part of initial therapy.”

The recommendations also addressed the risk for lung disease, “which is an emerging issue, particularly in children, that the physician should be very well aware of,” Dr. De Benedetti said. This complication can arise at any time point of the disease, he added.

The document advised actively screening for lung disease by searching for clinical symptoms such as digital clubbing, persistent cough, and shortness of breath. Pulmonary function tests like pulse oximetry and diffusing capacity of the lungs for carbon monoxide may also be used, but these standard lung function tests are very difficult to do in children under 6 years old, Dr. De Benedetti noted. The recommendations advise performing high-resolution CT in “any patients with clinical concerns.”

“We have lowered the threshold for CT scan because of the emerging features of this lung disease that may actually be lethal and therefore require prompt attention,” Dr. De Benedetti noted.

The recommendations for lung disease are “broad,” as there is still much to learn about the risk for lung disease in a small portion of sJIA patients, Dr. Onel said.

“There’s a lot that we are trying to work out about this; exactly how to screen, who to screen, what to do, who to treat, and how to treat really remains unclear,” she said. “We absolutely agree that this is a major, major issue that we need to come to some sort of agreement upon, but we’re just not there yet.”

Dr. De Benedetti, Dr. Fautrel, and Dr. Onel disclosed no relevant financial relationships.

Systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still’s disease (AOSD) should be grouped into one disease, Still’s disease, according to new diagnosis and treatment recommendations presented at the annual European Congress of Rheumatology.

The recommendations, made in collaboration with EULAR and the Pediatric Rheumatology European Society, emphasized that the ultimate treatment target for Still’s disease should be drug-free remission in all patients and that macrophage activation syndrome (MAS) should be identified and treated as soon as possible.

The task force focused on MAS because despite effective, innovative therapies, “we continued to see MAS,” said presenter Bruno Fautrel, MD, Pitié-Salpêtrière University Hospital, Paris. “We have to be very concerned about this potential complication.”

Dr. Fautrel copresented the recommendations with Fabrizio De Benedetti, MD, PhD, head of the division of rheumatology, Bambino Gesù Hospital, Rome.
 

Diagnosis

Dr. Fautrel noted that the cutoff age of 16 that differentiates sJIA and AOSD is “arbitrary.” There are some differences in age: The frequency of the disease is higher in young children, but it plateaus in young adults. Children under 18 months old are also far more likely to develop MAS.

To diagnose and treat Still’s disease, the recommendations state that clinicians should consider four criteria:

• A fever spiking at or above 39° C (102.2° F) for at least 7 days.
• A transient rash, preferentially on the trunk, that coincides with fever spikes, rash is typically erythematous but other rashes, like urticaria, can be consistent with the diagnosis.
• Some musculoskeletal involvement is common, involving arthralgia/myalgia.
• High levels of inflammation identified by neutrophilic leukocytosis, increased serum C-reactive protein (CRP), and ferritin.

Dr. Fautrel noted that, while arthritis can be present, it is not necessary to make a diagnosis. In pediatrics, “arthritis is likely to happen after a few weeks of the evolution of the disease,” and waiting for arthritis to develop can lead to diagnostic delay, “which is a problem.”

CHICAGO – For the chief patient officer of the American Cancer Society, this year’s annual meeting of the American Society of Clinical Oncology was a gem. And it didn’t just sparkle because of the sequined Taylor Swift fans clogging the nearby streets during the meeting.

Arif Kamal, MD, MBA, MHS, who is also an oncologist at Duke University, Durham, N.C., said he was impressed by a pair of landmark studies released at the meeting that show hidden cancer can be targeted with “really remarkable outcomes.” He also highlighted sessions that examined the role of artificial intelligence (AI) in oncology, during an interview.

Below are lightly edited excerpts from a conversation with Dr. Kamal:



Question: What are some of most groundbreaking studies released at ASCO?

Answer: One is an interim analysis of the NATALEE trial, which involved patients with early-stage hormone receptor-positive, HER2-negative (HR+/HER2–) breast tumors. This phase 3 randomized trial compared maintenance therapy with the cyclin-dependent kinase 4/6 (CDK4/6) inhibitor ribociclib (Kisqali) plus endocrine therapy with an aromatase inhibitor to endocrine therapy alone in patients with node-positive or node-negative and stage II or III HR+/HER– breast cancer.

For a long time, the standard care in these patients has been to use endocrine therapy alone. This is the first big trial to show that upstream usage of additional therapy in early stages is also beneficial for disease-free survival. The 3-year invasive disease-free survival rate was 90.4% in the rebociclib-endocrine therapy group vs. 87.1% for patients who received only endocrine therapy (P = .0014).



Q: How do these findings add to current knowledge?

A: Typically, we let people get metastatic disease before we use CDK4/6 inhibitors. These findings show that systemic treatment beyond endocrine therapy will be helpful in cases where you’ve got smaller disease that has not spread yet.

Even in patients with node-negative breast cancer, micrometastatic disease is clearly there, because the medication killed the negative lymph nodes.



Q: What else struck you as especially important research?

A: The NATALEE findings match what we saw in another study – the ADAURA trial, which looked at adjuvant osimertinib in non–small-cell lung cancer patients with EGFR-mutated, stage IB to IIIA disease – cancer that has not spread to the lymph nodes.

This is another example where you have a treatment being used in earlier-stage disease that’s showing really remarkable outcomes. The study found that 5-year overall survival was 88% in an osimertinib group vs. 78% in a placebo group (P < .001). This is a disease where, in stage IB, we wouldn’t even necessarily give these patients treatment at all, other than surgical resection of the tumor and maybe give them a little bit of chemotherapy.

Even in these smaller, early tumors, osimertinib makes a difference.



Q: As a whole, what are these studies telling us about cancer cells that can’t be easily detected?

A: To find a disease-free survival benefit with adding ribociclib in a stage II, stage III setting, particularly in node-negative disease, is remarkable because it says that the cells in hiding are bad actors, and they are going to cause trouble. The study shows that medications can find these cells and reverse that risk of bad outcomes.

If you think about the paradigm of cancer, that’s pretty remarkable because the ADAURA trial does the same thing: You do surgery for [early-stage] lung cancers that have not spread to the lymph nodes and you figure, “Well, I’ve got it all, right? The margins are real big, healthy, clean.” And yet, people still have recurrences, and you ask the same question: “Can any medicine find those few cells, the hundreds of cells that are still left somewhere in hiding?” And the answer is again, yes. It’s changing the paradigm of our understanding of minimal residual disease.

That’s why there’s so much interest in liquid biopsies. Let’s say that after treatment we don’t see any cancer radiologically, but there’s a signal from a liquid biopsy [detecting residual cancer]. These two trials demonstrate that there’s something we can do about it.



Q: There were quite a few studies about artificial intelligence released at ASCO. Where do we stand on that front?

A: We’re just at the beginning of people thinking about the use of generative AI for clinical decision support, clinical trial matching, and pathology review. But AI, at least for now, still has the issue of making up things that aren’t true. That’s not something patients are going to be okay with.



Q: How can AI be helpful to medical providers considering its limitations?

A: AI is going to be very good at the data-to-information transition. You’ll start seeing people use AI to start clinical notes for them and to match patients to the best clinical trials for them. But fundamentally, the clinician’s role will continue to be to check facts and offer wisdom.



Q: Will AI threaten the careers of oncologists?

A: The body of knowledge about oncology is growing exponentially, and no one can actually keep up. There’s so much data that’s out there that needs to be turned into usable information amid a shortage of oncologists. At the same time, the prevalence of cancer is going up, even though mortality is going down.

Synthesis of data is what oncologists are waiting for from AI. They’ll welcome it as opposed to being worried. That’s the sentiment I heard from my colleagues.

MILAN – Targeted synthetic and biologic therapies are recommended as disease-modifying agents for key fibrotic manifestations of systemic sclerosis for the first time in the 2023 update of European Alliance of Associations for Rheumatology recommendations for the treatment of systemic sclerosis.

Reflecting important advances over the past 8 years, mostly relating to the use of new treatments being made available to patients, the recommendations provide an update on the 2017 recommendations, which relied on evidence published through 2014. Of note, these include the use of immunosuppressive agents, for example, the monoclonal antibody rituximab (Rituxan) for skin and lung fibrosis.

“For the first time, synthetic and targeted treatments are recommended for the treatment of systemic sclerosis–interstitial lung disease, including mycophenolate mofetil [Cellcept], nintedanib [Ofev], rituximab, and tocilizumab [Actemra]. None of these were present in 2017. Mycophenolate mofetil is also recommended for the treatment of skin fibrosis, and this was not present in 2017,” Francesco Del Galdo, MD, rheumatology consultant at Leeds Teaching Hospital NHS Trust, Leeds, England, and member of the 2023 recommendations task force, said in an interview. He gave an overview of the preliminary recommendations at the annual European Congress of Rheumatology.

“Phosphodiesterase-5 [PDE-5] inhibitors and endothelin receptor antagonist [ERA] monotherapy are also recommended for up-front combination use for digital ulcers and pulmonary hypertension, and this is new for 2023 and was not present in the 2017 recommendations,” Dr. Del Galdo added.

The new recommendations also note that iloprost is categorized as having grade A evidence for use in Raynaud’s phenomenon and digital ulcers, while it has grade B evidence for pulmonary hypertension.

“We are not allowed to share the final table [of recommendations] today because the wording has only very recently been agreed” upon, Dr. Del Galdo said, but he provided a summary representation and reflected on some changes, noting that the task force is aiming to publish the 2023 recommendations by the end of the year.

Consideration and discussion of both established and new evidence highlighted a need for more evidence on the use of immunosuppressive agents in vascular manifestations of systemic sclerosis, as well as for gastrointestinal and musculoskeletal ones.

In this update to the 2017 recommendations, high-grade evidence was identified for use of immunosuppressants in skin and lung fibrosis. Grade A evidence has been accepted for the use of rituximab in skin fibrosis; for interstitial lung disease, rituximab, cyclophosphamide, and nintedanib also have grade A evidence, which is a change from the 2017 recommendations.

A total of 20 updated recommendations were agreed on, an increase from 16 in 2017. These were grouped into eight disease domains: Raynaud’s phenomenon, digital ulcers, pulmonary arterial hypertension, skin fibrosis, interstitial lung disease, musculoskeletal and gastrointestinal manifestations, and renal crisis. Interventions were then graded A-D based on the evidence reviewed.

“This approach allowed us to see clearly that there were patterns of similar recommendations in different organ manifestations, reflecting an understanding of common pathogenic pathways,” said Dr. Del Galdo.

He also noted that the development of the recommendations highlighted certain gaps in research that limit treatment options. “By grouping the recommendations in blocks – for example, skin fibrosis or vascular [manifestations] – we show that immunosuppressive treatments have only been studied in skin and lung, while vascular manifestations have very little evidence for immunosuppression. They might be effective but there’s no evidence yet [hence no recommendation in vascular manifestations].”

“Also, there’s no grade A evidence at all for musculoskeletal and gastrointestinal manifestations, and this should help to define the research agenda going forward,” Dr. Del Galdo said.

The 2023 recommendations task force comprised 28 members from 14 countries, including 18 rheumatologists, 1 EULAR methodologist, 1 health professional representative, 5 rheumatology fellows, 1 librarian, and 2 patient representatives. They used a consensual approach incorporating the views of 101 European Scleroderma Trials and Research group (EUSTAR) centers, sourced via a survey in which questions were advanced to an extensive systematic review if there was 70% or greater agreement.

Eventually, 31 questions on interventions were chosen, and the task force reviewed 12,500 abstracts (up to December 2022) related to interventions and outcomes that were either included in the 2017 recommendations or were totally new.

Dr. Del Galdo said that the three vascular manifestations of scleroderma – Raynaud’s, pulmonary arterial hypertension, and digital ulcers – were treated with the same drugs, all with a similar grade of evidence. “This suggests two things – firstly there’s a vascular disease continuum in the disease, and secondly, we’ve borrowed these drugs from vascular community, but we have not yet tested synthetic and biologic targeted treatments in these manifestations, and we should.

“Treating one manifestation may benefit the other, and this is important time wise because pulmonary hypertension usually comes around 10 years after the first phenomena so by treating digital ulcers and Raynaud’s phenomena, we may prevent pulmonary hypertension, but a study is needed,” added Dr. Del Galdo, who is also president of EUSTAR.

Finally, he pointed out that research remains particularly open for nonpharmacologic treatments for digital ulcers and severe gastrointestinal involvement. “Patients can now ask for studies into this because of the current lack of evidence.”

Moderator Ariane Herrick, PhD, professor of rheumatology at the University of Manchester (England), shared her thoughts on the guidelines. “These recommendations have been long awaited by the scleroderma community because there has been some exciting progress in recent years, and the new recommendations reflect these new developments.”

Commenting on the paucity of evidence in some areas, she added that “there do remain some huge areas of unmet need that are difficult to address, and these are musculoskeletal, gastrointestinal, and calcinosis, for which there have been no trials at all.”

Dr. Del Galdo declared disclosures relating to AstraZeneca, Janssen, Boehringer Ingelheim, Capella, Chemomab, GlaxoSmithKline, and Mitsubishi-Tanabe. Dr. Herrick disclosed serving as a consultant for Boehringer Ingelheim and Janssen.

“We are not allowed to share the final table [of recommendations] today because the wording has only very recently been agreed” upon, Dr. Del Galdo said, but he provided a summary representation and reflected on some changes, noting that the task force is aiming to publish the 2023 recommendations by the end of the year.

Consideration and discussion of both established and new evidence highlighted a need for more evidence on the use of immunosuppressive agents in vascular manifestations of systemic sclerosis, as well as for gastrointestinal and musculoskeletal ones.

In this update to the 2017 recommendations, high-grade evidence was identified for use of immunosuppressants in skin and lung fibrosis. Grade A evidence has been accepted for the use of rituximab in skin fibrosis; for interstitial lung disease, rituximab, cyclophosphamide, and nintedanib also have grade A evidence, which is a change from the 2017 recommendations.

A total of 20 updated recommendations were agreed on, an increase from 16 in 2017. These were grouped into eight disease domains: Raynaud’s phenomenon, digital ulcers, pulmonary arterial hypertension, skin fibrosis, interstitial lung disease, musculoskeletal and gastrointestinal manifestations, and renal crisis. Interventions were then graded A-D based on the evidence reviewed.

“This approach allowed us to see clearly that there were patterns of similar recommendations in different organ manifestations, reflecting an understanding of common pathogenic pathways,” said Dr. Del Galdo.

He also noted that the development of the recommendations highlighted certain gaps in research that limit treatment options. “By grouping the recommendations in blocks – for example, skin fibrosis or vascular [manifestations] – we show that immunosuppressive treatments have only been studied in skin and lung, while vascular manifestations have very little evidence for immunosuppression. They might be effective but there’s no evidence yet [hence no recommendation in vascular manifestations].”

“Also, there’s no grade A evidence at all for musculoskeletal and gastrointestinal manifestations, and this should help to define the research agenda going forward,” Dr. Del Galdo said.

The 2023 recommendations task force comprised 28 members from 14 countries, including 18 rheumatologists, 1 EULAR methodologist, 1 health professional representative, 5 rheumatology fellows, 1 librarian, and 2 patient representatives. They used a consensual approach incorporating the views of 101 European Scleroderma Trials and Research group (EUSTAR) centers, sourced via a survey in which questions were advanced to an extensive systematic review if there was 70% or greater agreement.

Eventually, 31 questions on interventions were chosen, and the task force reviewed 12,500 abstracts (up to December 2022) related to interventions and outcomes that were either included in the 2017 recommendations or were totally new.

Dr. Del Galdo said that the three vascular manifestations of scleroderma – Raynaud’s, pulmonary arterial hypertension, and digital ulcers – were treated with the same drugs, all with a similar grade of evidence. “This suggests two things – firstly there’s a vascular disease continuum in the disease, and secondly, we’ve borrowed these drugs from vascular community, but we have not yet tested synthetic and biologic targeted treatments in these manifestations, and we should.

“Treating one manifestation may benefit the other, and this is important time wise because pulmonary hypertension usually comes around 10 years after the first phenomena so by treating digital ulcers and Raynaud’s phenomena, we may prevent pulmonary hypertension, but a study is needed,” added Dr. Del Galdo, who is also president of EUSTAR.

Finally, he pointed out that research remains particularly open for nonpharmacologic treatments for digital ulcers and severe gastrointestinal involvement. “Patients can now ask for studies into this because of the current lack of evidence.”

Moderator Ariane Herrick, PhD, professor of rheumatology at the University of Manchester (England), shared her thoughts on the guidelines. “These recommendations have been long awaited by the scleroderma community because there has been some exciting progress in recent years, and the new recommendations reflect these new developments.”

Commenting on the paucity of evidence in some areas, she added that “there do remain some huge areas of unmet need that are difficult to address, and these are musculoskeletal, gastrointestinal, and calcinosis, for which there have been no trials at all.”

Dr. Del Galdo declared disclosures relating to AstraZeneca, Janssen, Boehringer Ingelheim, Capella, Chemomab, GlaxoSmithKline, and Mitsubishi-Tanabe. Dr. Herrick disclosed serving as a consultant for Boehringer Ingelheim and Janssen.

MILAN – Targeted synthetic and biologic therapies are recommended as disease-modifying agents for key fibrotic manifestations of systemic sclerosis for the first time in the 2023 update of European Alliance of Associations for Rheumatology recommendations for the treatment of systemic sclerosis.

Reflecting important advances over the past 8 years, mostly relating to the use of new treatments being made available to patients, the recommendations provide an update on the 2017 recommendations, which relied on evidence published through 2014. Of note, these include the use of immunosuppressive agents, for example, the monoclonal antibody rituximab (Rituxan) for skin and lung fibrosis.

“For the first time, synthetic and targeted treatments are recommended for the treatment of systemic sclerosis–interstitial lung disease, including mycophenolate mofetil [Cellcept], nintedanib [Ofev], rituximab, and tocilizumab [Actemra]. None of these were present in 2017. Mycophenolate mofetil is also recommended for the treatment of skin fibrosis, and this was not present in 2017,” Francesco Del Galdo, MD, rheumatology consultant at Leeds Teaching Hospital NHS Trust, Leeds, England, and member of the 2023 recommendations task force, said in an interview. He gave an overview of the preliminary recommendations at the annual European Congress of Rheumatology.

“Phosphodiesterase-5 [PDE-5] inhibitors and endothelin receptor antagonist [ERA] monotherapy are also recommended for up-front combination use for digital ulcers and pulmonary hypertension, and this is new for 2023 and was not present in the 2017 recommendations,” Dr. Del Galdo added.

A team of researchers has identified genomic variants that cause disabling pansclerotic morphea (DPM), a rare, severe inflammatory skin disorder, and report that the Janus kinase (JAK) inhibitor ruxolitinib may be a useful therapy, especially in patients who have not responded to other interventions.

DPM was first reported in 1923, and while a genetic cause has been suspected, it had not been identified until now. The disease is the most severe form of deep morphea, which affects individuals with juvenile localized scleroderma. Patients, generally children under age 14, experience rapid sclerosis of all layers of the skin, fascia, muscle, and bone. DPM is also deadly: Most patients do not live more than 10 years after diagnosis, as they contract squamous cell carcinoma, restrictive pulmonary disease, sepsis, and gangrene.

In the study, published in the New England Journal of Medicine, the researchers discovered that people with DPM have an overactive version of the protein STAT4, which regulates inflammation and wound healing. The scientists studied four patients from three unrelated families with an autosomal dominant pattern of inheritance of DPM.

“Researchers previously thought that this disorder was caused by the immune system attacking the skin,” Sarah Blackstone, a predoctoral fellow in the inflammatory disease section at the National Human Genome Research Institute and co–first author of the study, said in a statement from the National Institutes of Health describing the results. “However, we found that this is an oversimplification, and that both skin and the immune system play an active role in disabling pansclerotic morphea,” added Ms. Blackstone, also a medical student at the University of South Dakota, Sioux Falls.

The overactive STAT4 protein creates a positive feedback loop of inflammation and impaired wound-healing. By targeting JAK, the researchers were able to stop the feedback and patients’ wounds dramatically improved. After 18 months of treatment with oral ruxolitinib, one patient had discontinued all other medications, and had complete resolution of a chest rash, substantial clearing on the arms and legs, and global clinical improvement.

The authors said that oral systemic JAK inhibitor therapy is preferred over topical therapy. Their research also suggested that anti–interleukin-6 monoclonal antibodies – such as tocilizumab, approved for indications that include rheumatoid arthritis and systemic sclerosis–associated interstitial lung disease, “may be an alternative therapy or may be useful in combination with JAK inhibitors in patients with DPM,” the authors wrote.

Most current DPM therapies – including methotrexate, mycophenolate mofetil, and ultraviolet A light therapy – have been ineffective, and some have severe side effects.

“The findings of this study open doors for JAK inhibitors to be a potential treatment for other inflammatory skin disorders or disorders related to tissue scarring, whether it is scarring of the lungs, liver or bone marrow,” Dan Kastner, MD, PhD, an NIH distinguished investigator, head of the NHGRI’s inflammatory disease section, and a senior author of the paper, said in the NIH statement.

“We hope to continue studying other molecules in this pathway and how they are altered in patients with disabling pansclerotic morphea and related conditions to find clues to understanding a broader array of more common diseases,” Lori Broderick, MD, PhD, a senior author of the paper and an associate professor at University of California, San Diego, said in the statement.

The study was led by researchers at NHGRI in collaboration with researchers from UCSD and the University of Pittsburgh. Researchers from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the National Institute of Allergy and Infectious Diseases also participated.

The study was supported by grants from the American Academy of Allergy, Asthma, and Immunology Foundation; the Ludwig Institute for Cancer Research; the University of California, San Diego, department of pediatrics; and the Novo Nordisk Foundation. Additional support and grants were given by the Deutsche Forschungsgemeinschaft, various institutes at the NIH, the California Institute for Regenerative Medicine, the Hydrocephalus Association, the Scleroderma Research Foundation, the Biowulf High-Performance Computing Cluster of the Center for Information Technology, the Undiagnosed Diseases Program of the Common Fund of the Office of the Director of the NIH, and the NIH Clinical Center.

The U.S. Food and Drug Administration has approved the biosimilar adalimumab-aaty (Yuflyma) in a citrate-free, high-concentration formulation, the manufacturer, Celltrion USA, announced today. It is the ninth biosimilar of adalimumab (Humira) to be approved in the United States.
 

Yuflyma is approved for the treatment of adult patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa. It is also approved for polyarticular juvenile idiopathic arthritis for patients aged 2 years or older, as well as for Crohn’s disease in adults and in pediatric patients aged 6 years or older.

The formulation was approved on the basis of a comprehensive data package of analytic, preclinical, and clinical studies, according to Celltrion USA, “demonstrating that Yuflyma is comparable to the reference product Humira in terms of efficacy, safety, pharmacokinetics, and immunogenicity up to 24 weeks and 1 year following treatment.”

The company conducted a double-blind, randomized phase 3 trial that compared switching from reference adalimumab to Yuflyma with continuing either reference adalimumab or Yuflyma for patients with active rheumatoid arthritis. In that trial, the efficacy, pharmacokinetics, safety, and immunogenicity of Yuflyma and reference adalimumab were comparable after 1 year of treatment, including after switching from reference adalimumab to Yuflyma.

“Currently, more than 80% of patients treated with Humira in the United States rely on a high-concentration and citrate-free formulation of this medication. The availability of a high-concentration and citrate-free formulation adalimumab biosimilar provides an important treatment option for patients with inflammatory diseases who benefit from this effective therapy,” said Jonathan Kay, MD, of the University of Massachusetts, Worcester, in the press release.

The citrate-free formulation is thought to lead to less pain on injection.

Yuflyma will be available in prefilled syringe and autoinjector administration options.

Celltrion USA plans to market the drug in the United States in July 2023. Following the initial launch of 40 mg/0.4 mL, the company plans to launch dose forms of 80 mg/0.8 mL and 20 mg/0.2 mL.

Celltrion USA is also seeking an interchangeability designation from the FDA following the completion of an interchangeability trial of 366 patients with chronic plaque psoriasis. The interchangeability designation would mean that patients successfully switched from Humira to Yuflyma multiple times in the trial. The interchangeability designation would allow pharmacists to autosubstitute Humira with Yuflyma. In these cases, individual state laws control how and whether physicians will be notified of this switch.

If interchangeability is approved for Yuflyma, which the company tentatively expects in the fourth quarter of 2024, it would be just the third interchangeable biosimilar approved by the FDA overall and the second adalimumab biosimilar to be designated as such, after adalimumab-adbm (Cyltezo) in October 2021.

Yuflyma was approved in Canada in December 2021 for 10 indications: rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult Crohn’s disease, adult ulcerative colitis, hidradenitis suppurativa, plaque psoriasis, adult uveitis, and pediatric uveitis.

In February 2022, the European Commission granted marketing authorization for Yuflyma across those 10 indications, as well as for nonradiographic axial spondyloarthritis, pediatric plaque psoriasis, and pediatric Crohn’s disease.

In April 2022, Celltrion USA signed a licensing agreement with AbbVie, the manufacturer of Humira. Under that agreement, Celltrion will pay royalties to AbbVie on sales of their individual biosimilars, and AbbVie agreed to drop all patent litigation.

The full prescribing information for Yuflyma is available here.

Cyltezo was approved by the FDA in 2017 as a prefilled syringe and was the first biosimilar deemed to be interchangeable with Humira in 2021. It is indicated to treat multiple chronic inflammatory conditions, including rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, plaque psoriasis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, and hidradenitis suppurativa. This new design, which features one-button, three-step activation, has been certified as an “Ease of Use” product by the Arthritis Foundation, Boehringer Ingelheim said in a press release. The 40-mg, prefilled Cyltezo Pen will be available in two-, four-, and six-pack options.

“The FDA approval of the Cyltezo Pen is great news for patients living with chronic inflammatory diseases who may prefer administering the medication needed to manage their conditions via an autoinjector,” said Stephen Pagnotta, the executive director and biosimilar commercial lead at Boehringer Ingelheim in a statement; “we’re excited to be able to offer the Cyltezo Pen as an additional option to patients at Cyltezo’s launch on July 1.”

Patients with arginine vasopressin deficiency (AVD) appear to also be deficient in oxytocin, the “love hormone,” suggesting a possible pathway for treating the psychological symptoms associated with the illness.
 

Formerly known as central diabetes insipidus, AVD is a rare neuroendocrine condition in which fluid isn’t regulated, leading to polydipsia and polyuria. The vasopressin receptor 2 agonist desmopressin treats those symptoms, but patients often also experience psychopathological problems, such as increased anxiety, depression, and emotional withdrawal.

It has been hypothesized that those symptoms are caused by a concurrent deficiency of the so-called “love hormone” oxytocin, given the anatomic proximity of vasopressin and oxytocin production in the brain.

Now, for the first time, researchers have demonstrated evidence of that phenomenon using 3,4-methylenedioxymethamphetamine (MDMA, also known as “ecstasy”) to provoke oxytocin release. In individuals without AVD, use of MDMA resulted in large increases in plasma oxytocin concentrations, whereas there was very little response among those with AVD, suggesting that the latter patients were deficient in oxytocin.

“These findings are suggestive of a new hypothalamic–pituitary disease entity and contribute to deepening our understanding of oxytocin as a key hormone in centrally generated socioemotional effects, as reflected by reduced prosocial, empathic, and anxiolytic effects in patients with an oxytocin deficiency,” Cihan Atila, MD, of the University of Basel (Switzerland), and colleagues wrote.

“Future studies should evaluate whether oxytocin replacement therapy can alleviate residual symptoms related to oxytocin deficiency in patients with [AVD],” they added.

The findings, from a single-center study of 15 patients with AVD and 15 healthy control persons, were published online in The Lancet Diabetes and Endocrinology.

“Atila and colleagues provide compelling evidence for a clinically relevant oxytocin deficiency in this population of patients, which appears to be at least partly responsible for the associated increase in psychopathological findings,” say Mirela Diana Ilie, MD, an endocrinologist in training at the National Institute of Endocrinology, Bucharest, Romania, and Gérald Raverot, MD, professor of endocrinology at Lyon (France) University Hospital, France, in an accompanying editorial.

“From a therapeutic viewpoint, the findings ... pave the way to intervention studies assessing the effect of intranasal oxytocin in patients with [AVD] and better clinical care for these patients,” they add.

However, Dr. Ilie and Dr. Raverot urged caution for a variety of reasons, including the fact that, thus far, only one patient with arginine vasopressin deficiency has been administered oxytocin on a long-term basis. They suggested further studies to answer many pertinent questions, such as what the appropriate doses and frequency of oxytocin administration are, whether the dose should remain constant or be increased during stress or particular acute situations, whether long-term administration is suitable for all patients regardless of the extent of oxytocin deficiency, and how follow-up should be conducted.

“Answering these questions seems all the more important considering that oxytocin therapy has shown conflicting results when administered for psychiatric disorders,” said Dr. Ilie and Dr. Raverot.

In the meantime, “independent of the potential use of oxytocin, given the frequent and important psychological burden of [AVD], clinicians should screen patients for psychological comorbidities and should not hesitate to refer them to appropriate psychological and psychiatric care,” the editorialists wrote.
 

Eightfold increase in plasma oxytocin levels in patients vs. control persons

The 15 AVD patients and 15 matched healthy control persons were recruited between Feb. 1, 2021, and May 1, 2022. Of those with AVD, eight had an isolated posterior pituitary dysfunction, and seven had a combined pituitary dysfunction. The patients had significantly higher scores on measures of anxiety, alexithymia, and depression, and self-reported mental health was lower, compared with control persons.

All participants were randomly assigned to receive either a single oral dose of MDMA 100 mg or placebo in the first experimental session and the opposite treatment in a second session. There was a 2-week washout period in between.

Median oxytocin concentrations at baseline were 77 pg/mL in the healthy control persons and peaked after MDMA stimulation to 624 pg/mL after 180 minutes, with a maximum of 659 pg/mL. In contrast, among the patients with AVD, baseline oxytocin levels were 60 pg/mL and peaked to just 92 pg/mL after 150 minutes, with a maximum change in concentration of 66 pg/mL.

In response to MDMA, there was an eightfold increase in plasma oxytocin area under the curve among the control persons versus no notable increase in the patients with AVD.

The net incremental oxytocin area under the curve after MDMA administration was 82% higher among control persons than patients (P < .0001).

The MDMA-induced increase in oxytocin was associated with reduced anxiety scores among the control persons but not the AVD patients. Similar results were seen for subjective prosocial and empathic effects.

The most frequently reported adverse effects of the MDMA provocation in both groups were fatigue, lack of appetite, and dry mouth, all of which occurred in more than half of participants.

“These findings contradict the previous theory that oxytocin stimulation has only a secondary role in the effects of MDMA. Our results, by contrast, suggest a paradigm shift and underline the importance of oxytocin as a key feature of the effects of MDMA,” Dr. Atila and colleagues concluded.

Dr. Atila, Dr. Ilie, and Dr. Raverot have disclosed no relevant financial relationships. One study coauthor owns stock in MiniMed.

The U.S. Food and Drug Administration has approved the first-ever topical gene therapy, which will be used to treat wounds in patients 6 months of age and older who have either recessive or dominant dystrophic epidermolysis bullosa (DEB), a rare skin disease.

Olivier Le Moal/Getty Images

The therapy, Vyjuvek (beremagene geperpavec, formerly known as B-VEC), uses a nonreplicating herpes simplex virus type 1 (HSV-1) vector to deliver the COL7A1 gene directly to skin cells, restoring the COL7 protein fibrils that stabilize skin structure.

Vyjuvek, developed by Krystal Biotech, is designed to be used repetitively to heal a single wound or on more than one wound. In the pivotal study, the gene therapy, delivered in a topical gel, was administered once a week for 6 months.

The FDA gave Vyjuvek priority review, approving the therapy just 9 months after Krystal filed its application for approval. Vyjuvek is also an orphan drug, giving it potentially 7 years of marketing exclusivity.

“Vyjuvek is the first FDA-approved gene therapy treatment for DEB, a rare and serious genetic skin disorder,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in the FDA’s statement  announcing the approval.

“With the FDA approval of Vyjuvek, the DEB population has reached a monumental milestone in the treatment of this horrible disorder,” said Brett Kopelan, executive director of debra of America, a national advocacy group for people with DEB, in a statement issued by Krystal Biotech. “Our hopes have now been realized for a safe and effective treatment for one of the most devastating symptoms of the disorder,” said Mr. Kopelan.

“This is a devastating disease,” said M. Peter Marinkovich, MD, primary investigator of Krystal’s pivotal GEM-3 trial and director of the Blistering Disease Clinic at Stanford Health Care, in the statement issued by Krystal. “Until now, doctors and nurses had no way to stop blisters and wounds from developing on dystrophic EB patient skin, and all we could do was to give them bandages and helplessly watch as new blisters formed,” said Dr. Marinkovich, who is also associate professor of dermatology at Stanford (Calif.) University School of Medicine.

“Because it’s safe and easy to apply directly to wounds, it doesn’t require a lot of supporting technology or specialized expertise, making Vyjuvek highly accessible even to patients who live far away from specialized centers,” he said.

Paras P. Vakharia, MD, PharmD, assistant professor of dermatology at Northwestern University, Chicago, said that Vyjuvek is an important advance for DEB. “This to me would be a treatment that I would consider for almost all patients,” Dr. Vakharia said in an interview.

Dr. Vakharia, who was not involved with trials of Vyjuvek, said he had concerns about whether patients might develop antibodies to either HSV or C7 but that the greater initial worry is if Vyjuvek will be affordable and accessible. “I envision that it will be a costly medication,” he said.

Mr. Kopelan, the patient advocate, said that his organization “will continue to work closely with Krystal to assure patients have ready access to Vyjuvek.”

Krystal did not respond before press time to a request for comment on pricing.

Dystrophic epidermolysis bullosa affects 1 to 3 people per million in the United States. It is caused by mutations in the COL7A1 gene, which encodes the alpha-1 chain of collagen type VII (C7) protein. C7 forms the anchoring fibrils that attach the epidermis to the underlying dermal connective tissue. COL71A mutations that lead to defective, decreased, or absent C7 can make the skin so fragile that it tears with the slightest touch.

DEB usually presents at birth and is divided into two major types depending on the inheritance pattern: recessive dystrophic epidermolysis bullosa and dominant dystrophic epidermolysis bullosa.

People with the dominant form typically have mild cases with blistering primarily on the hands, feet, knees, and elbows. The recessive form can be painful and debilitating, causing widespread blistering. Depending on the severity, it can lead to nonhealing wounds, fusing of fingers and toes, anemia, weak bones, and esophageal and genitourinary strictures. Squamous cell cancers are a frequent cause of death.

Vyjuvek is mixed into an inactive gel and is evenly applied to a wound once a week by a health care professional, according to the FDA.  

The agency recommends the following precautions for patients and caregivers:

• Avoid direct contact with treated wounds and dressings of treated wounds for 24 hours following application. Clean any area that is accidentally exposed.
• Wash hands and wear protective gloves when changing wound dressings.
• Disinfect the bandages used for the first dressing with a viricidal agent, such as 70% isopropyl alcohol, 6% hydrogen peroxide, or less than 0.4% ammonium chloride, and dispose of them in a separate, sealed plastic bag in household waste. Subsequent used dressings and cleaning materials should be disposed of in sealed plastic bags in household waste.

FDA approval of Vyjuvek was based on a randomized, double-blinded, placebo-controlled, 31-patient, phase 3 trial published in the New England Journal of Medicine, which showed that 71% of wounds treated with the gene therapy had complete healing at 3 months, compared with 20% of those treated with placebo (95% confidence interval, 29-73; P < .001). At 6 months, 67% of wounds treated with the gene therapy had complete healing, compared with 22% of wounds treated with placebo (95% CI, 24-68; P = .002).

Almost two-thirds of the patients had at least one adverse event. Most were mild or moderate. The most common events were pruritus, chills, and squamous cell carcinoma, reported in three patients each. SCC cases occurred at wound sites that had not been exposed to Vyjuvek or placebo. Serious adverse events, which were unrelated to the treatment, occurred in three patients and included diarrhea, anemia, and cellulitis.

Krystal will also be seeking marketing approval for Vyjuvek in the European Union, likely in 2024, said the company. In September, the European Medicines Agency’s Pediatric Committee issued a positive opinion on the gene therapy and Krystal’s plan to test B-VEC in children.

Dr. Marinkovich and Dr. Vakharia have disclosed no relevant financial relationships.

Vyjuvek, developed by Krystal Biotech, is designed to be used repetitively to heal a single wound or on more than one wound. In the pivotal study, the gene therapy, delivered in a topical gel, was administered once a week for 6 months.

The FDA gave Vyjuvek priority review, approving the therapy just 9 months after Krystal filed its application for approval. Vyjuvek is also an orphan drug, giving it potentially 7 years of marketing exclusivity.

“Vyjuvek is the first FDA-approved gene therapy treatment for DEB, a rare and serious genetic skin disorder,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in the FDA’s statement  announcing the approval.

“With the FDA approval of Vyjuvek, the DEB population has reached a monumental milestone in the treatment of this horrible disorder,” said Brett Kopelan, executive director of debra of America, a national advocacy group for people with DEB, in a statement issued by Krystal Biotech. “Our hopes have now been realized for a safe and effective treatment for one of the most devastating symptoms of the disorder,” said Mr. Kopelan.

“This is a devastating disease,” said M. Peter Marinkovich, MD, primary investigator of Krystal’s pivotal GEM-3 trial and director of the Blistering Disease Clinic at Stanford Health Care, in the statement issued by Krystal. “Until now, doctors and nurses had no way to stop blisters and wounds from developing on dystrophic EB patient skin, and all we could do was to give them bandages and helplessly watch as new blisters formed,” said Dr. Marinkovich, who is also associate professor of dermatology at Stanford (Calif.) University School of Medicine.

“Because it’s safe and easy to apply directly to wounds, it doesn’t require a lot of supporting technology or specialized expertise, making Vyjuvek highly accessible even to patients who live far away from specialized centers,” he said.

Paras P. Vakharia, MD, PharmD, assistant professor of dermatology at Northwestern University, Chicago, said that Vyjuvek is an important advance for DEB. “This to me would be a treatment that I would consider for almost all patients,” Dr. Vakharia said in an interview.

Dr. Vakharia, who was not involved with trials of Vyjuvek, said he had concerns about whether patients might develop antibodies to either HSV or C7 but that the greater initial worry is if Vyjuvek will be affordable and accessible. “I envision that it will be a costly medication,” he said.

Mr. Kopelan, the patient advocate, said that his organization “will continue to work closely with Krystal to assure patients have ready access to Vyjuvek.”

Krystal did not respond before press time to a request for comment on pricing.

Dystrophic epidermolysis bullosa affects 1 to 3 people per million in the United States. It is caused by mutations in the COL7A1 gene, which encodes the alpha-1 chain of collagen type VII (C7) protein. C7 forms the anchoring fibrils that attach the epidermis to the underlying dermal connective tissue. COL71A mutations that lead to defective, decreased, or absent C7 can make the skin so fragile that it tears with the slightest touch.

DEB usually presents at birth and is divided into two major types depending on the inheritance pattern: recessive dystrophic epidermolysis bullosa and dominant dystrophic epidermolysis bullosa.

People with the dominant form typically have mild cases with blistering primarily on the hands, feet, knees, and elbows. The recessive form can be painful and debilitating, causing widespread blistering. Depending on the severity, it can lead to nonhealing wounds, fusing of fingers and toes, anemia, weak bones, and esophageal and genitourinary strictures. Squamous cell cancers are a frequent cause of death.

Vyjuvek is mixed into an inactive gel and is evenly applied to a wound once a week by a health care professional, according to the FDA.  

The agency recommends the following precautions for patients and caregivers:

• Avoid direct contact with treated wounds and dressings of treated wounds for 24 hours following application. Clean any area that is accidentally exposed.
• Wash hands and wear protective gloves when changing wound dressings.
• Disinfect the bandages used for the first dressing with a viricidal agent, such as 70% isopropyl alcohol, 6% hydrogen peroxide, or less than 0.4% ammonium chloride, and dispose of them in a separate, sealed plastic bag in household waste. Subsequent used dressings and cleaning materials should be disposed of in sealed plastic bags in household waste.

FDA approval of Vyjuvek was based on a randomized, double-blinded, placebo-controlled, 31-patient, phase 3 trial published in the New England Journal of Medicine, which showed that 71% of wounds treated with the gene therapy had complete healing at 3 months, compared with 20% of those treated with placebo (95% confidence interval, 29-73; P < .001). At 6 months, 67% of wounds treated with the gene therapy had complete healing, compared with 22% of wounds treated with placebo (95% CI, 24-68; P = .002).

Almost two-thirds of the patients had at least one adverse event. Most were mild or moderate. The most common events were pruritus, chills, and squamous cell carcinoma, reported in three patients each. SCC cases occurred at wound sites that had not been exposed to Vyjuvek or placebo. Serious adverse events, which were unrelated to the treatment, occurred in three patients and included diarrhea, anemia, and cellulitis.

Krystal will also be seeking marketing approval for Vyjuvek in the European Union, likely in 2024, said the company. In September, the European Medicines Agency’s Pediatric Committee issued a positive opinion on the gene therapy and Krystal’s plan to test B-VEC in children.

Dr. Marinkovich and Dr. Vakharia have disclosed no relevant financial relationships.
