ADA 2025: Progress in Managing Type 1 Diabetes
This transcript has been edited for clarity. The one study that my patients with type 1 diabetes asked me about from the American Diabetes Association meetings was the Vertex study, where stem cell-derived islet cells were given to individuals with type 1 diabetes and followed for a year. They reported on 12 participants, and basically, these little islet cells worked. The problem, of course — and the reason I had to disappoint my patients — is that it didn't work without immunosuppression. These patients required immunosuppression, but in the setting of immunosuppression, the little new islet cells worked. We saw an increase in C-peptide production. Most patients got off of insulin. The patients had no further episodes of severe hypoglycemia, and the patients really were cured, in essence, of their type 1 diabetes — at least the small number of people followed for a year. The downside, of course, is the immunosuppression, and that's where the side effects occurred. I think this was really interesting because it's certainly proof of concept that we can take stem cells, make islet cells, and infuse them into people and have them work. We just have to figure out a way to do it without immunosuppression. The next study that my patients and I found interesting came from the Barbara Davis Center and was done by Dr Halis Akturk and his colleagues. It was looking at the use of semaglutide 1 mg as an adjunct to insulin in people with type 1 diabetes and obesity who are on automated insulin delivery systems. Now, in full disclosure, I do this all the time in my patients who are overweight or obese who wish to try combination therapy off-label with semaglutide, but this is the first randomized controlled trial to show the benefit. This was called the ADJUST-T1D trial. It was a double-blind study. This was a 26-week placebo-controlled study, and they enrolled 72 individuals with type 1 diabetes from four US clinics. They were randomized 1:1 to semaglutide or placebo once weekly while they continued on their usual automated insulin delivery systems. The insulin adjustments were guided by the investigators, along with the patients, looking at time in range, time below range, and other continuous glucose monitoring parameters. These individuals had to have a BMI ≥ 30 and an A1c between 7% and 10% coming into the study. These are fairly typical individuals with type 1 diabetes who are overweight, and they had a baseline A1c of 7.7%. The primary outcome was a composite one, looking at how many people achieved a time in range of > 70%, time below range of < 4%, and ≥ 5% weight loss. This composite endpoint was met in 36% of the participants in the semaglutide group, and this was highly significant compared to the placebo group. In terms of secondary outcomes, there was a reduction in A1c by 0.7% in the semaglutide group compared to 0.3% in the placebo group. Time in range improved. People lost, on average, 18 lb, and there was a reduction in total daily insulin dose. There was no diabetic ketoacidosis, but there were two episodes of severe hypoglycemia in each group. This was really proof of concept, which I think all of us who treat many people with type 1 diabetes and have been using incretin therapy have shown to be beneficial. I think the things we still need to watch for is obviously weight loss that's too fast because I don't think this is good for anybody, and the fact that people will need less insulin, so the insulin doses need to be reduced as people use these agents. Patients on these automated insulin delivery systems tend to do pretty well. I'm often adjusting the carb ratio and maybe the sensitivity depending on the pump, but I found this to be a pretty safe and effective way to do it. I think you just start lower, you go up slowly, and you make sure patients are tolerating the medication. I think patients really see benefit. What's not measured here are the nonglycemic benefits that we know are part of the use of incretin therapies, which I think is important. In my own clinic, I looked at outcomes at 2 years retrospectively, and people had still maintained the weight loss but some of the glycemic improvements waned over time. I think that just goes to show the difficulty of managing people with type 1 diabetes. I think this helps, and I think this was a really good trial. I'm very grateful to the investigators for doing this study. These two presentations highlight some of the progress in how we're thinking about dealing with type 1 diabetes. First, the notion of hopefully, someday having a cure that helps people with type 1 diabetes, having new beta cells that actually work. The second is using some of the drugs that we're now familiar with in terms of their benefits to people with type 2 diabetes in people with type 1 diabetes, and showing that it can be done safely and effectively. This has been Dr Anne Peters for Medscape. Thank you.

Cancer Risk in MMF-Treated Patients Differs by Indication
TOPLINE: Patients with dermatologic conditions showed a 74% lower risk for malignancy with mycophenolate mofetil (MMF) than transplant patients, a study found. METHODOLOGY: Researchers conducted a single-center retrospective chart of patients who had taken MMF for ≥ 5 years between 2012 and 2025 at Atrium Health Wake Forest Baptist Medical Center. The analysis included 126 patients (mean age, 64.2 years; 35.7% men) who received MMF for dermatologic conditions, 226 organ transplant recipients (mean age, 59.6 years; 61.5% men) who received MMF plus other immunosuppressive agents, and 296 patients (mean age, 64.1 year; 34.5% men) with dermatologic conditions who had no exposure to systemic immunosuppression. About two thirds of patients were White individuals and one fourth were Black individuals. Dermatologic patients received a mean daily MMF dose of 1390 mg over an average of 7.5 years, while transplant recipients received a lower mean daily dose of 807 mg for a mean duration of 9.9 years. Concomitant immunosuppressive therapy was administered to 40% of the patients with dermatologic conditions (MMF plus prednisone) and to 100% of transplant recipients (tacrolimus, prednisone, or cyclosporine). Researchers compared malignancy rates between the groups. TAKEAWAY: Overall, 9.5% of the dermatologic patients who received MMF developed malignancies compared with 36% of the transplant recipients (P < .0001); the risk for malignancy was 74% lower in dermatologic patients treated with MMF (95% CI, 0.1487-0.4518). No difference was found between dermatologic patients who received MMF vs those without exposure to systemic immunosuppression (8.4%). Cutaneous malignancies were significantly more common in transplant patients than in dermatologic patients who received MMF (26.5% vs 5.6%; P < .0001). The prevalence of urological/reproductive cancers was higher in transplant patients than dermatologic patients treated with MMF (9.3% vs 2.4%; P = .0143). IN PRACTICE: 'The use of MMF for dermatologic conditions does not appear to expose patients to the same malignancy risk as those treated with MMF and other chronic immunosuppressive treatments in the transplant setting and did not confer an elevated malignancy risk compared to dermatologic patients without systemic immunosuppression,' the authors of the study wrote. SOURCE: The study was led by Robin Yi, Department of Dermatology, Wake Forest University School of Medicine, Winston-Salem, North Carolina, and was published online on July 17 in the Journal of the American Academy of Dermatology. LIMITATIONS: Limitations included the MMF dosing variability and small sample size. DISCLOSURES: The study did not receive any funding. One author reported receiving research, speaking and consulting support from numerous pharmaceutical companies including Eli Lilly, GlaxoSmithKline/Stiefel, AbbVie, and Janssen and disclosed being founder and part owner of Causa Research and holding stock in Sensal Health. This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

Sarepta Provides Safety Update for ELEVIDYS and Initiates Steps to Strengthen Safety in Non-Ambulatory Individuals with Duchenne
- The Company is developing an enhanced immunosuppressive regimen in consultation with a panel of multi-disciplinary clinical experts and engaging with regulators - Shipments of ELEVIDYS for infusions in non-ambulatory patients in commercial setting are suspended until enhanced regimen is approved and in place - ENVISION study is paused while seeking a protocol amendment to incorporate additional immunosuppression - Sarepta to host investor call on June 16, 2025, at 8:00 am Eastern time CAMBRIDGE, Mass., June 15, 2025--(BUSINESS WIRE)--Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today provided a safety update regarding ELEVIDYS (delandistrogene moxeparvovec-rokl), the only approved gene therapy for patients with Duchenne muscular dystrophy, and steps the Company is taking to strengthen the safety profile in non-ambulatory patients. These steps follow a second reported case of acute liver failure (ALF) resulting in death. The cases of ALF to date have both occurred in non-ambulatory individuals with Duchenne. Sarepta extends its deepest sympathies to the affected families and care teams. Key Safety Initiatives Evaluating and Enhancing Immunosuppressive Regimen: As part of a comprehensive review of safety data, Sarepta is taking proactive steps to mitigate the risk of acute liver failure in non-ambulatory patients. Sarepta is working to immediately convene an independent group of leading experts in Duchenne and liver health to consider an enhanced immunosuppression regimen for ELEVIDYS. This panel will evaluate data and assess our proposed regimen, which includes sirolimus and is supported by preclinical data demonstrating the effectiveness of additional immunosuppression in moderating liver enzyme elevations, a key factor in mitigating potential safety events. Sarepta will share the panel's recommendations with the U.S. Food & Drug Administration (FDA), and implementation of any new regimen will be subject to FDA guidance and allowance. Suspending Shipments of ELEVIDYS for Non-Ambulatory Patients: Sarepta is temporarily suspending shipments of ELEVIDYS for non-ambulatory patients while an enhanced immunosuppressive regimen is evaluated, discussed with regulatory bodies, and put in place. For ambulatory patients, no treatment changes are being proposed and the current practice of administering corticosteroids before and after ELEVIDYS infusion, along with post-treatment monitoring, remains the same. ENVISION Study Paused: Sarepta has voluntarily paused dosing in the ENVISION clinical study (also known as Study SRP-9001-303). FDA concurs with this action. The pause will allow for the evaluation of a protocol amendment to incorporate an enhanced immunosuppressive regimen for the non-ambulatory patient cohort and incorporate any additional feedback from the FDA. Regulatory alignment is needed before screening and dosing in ENVISION may resume. ENVISION is a global, randomized, double-blind, placebo-controlled trial evaluating ELEVIDYS in older ambulatory and non-ambulatory individuals living with Duchenne muscular dystrophy. In the U.S., it serves as the confirmatory trial required under the FDA's accelerated approval pathway for non-ambulatory patients. "Our paramount priority is the safety and well-being of the patients we serve. We are taking immediate, decisive steps to better understand and mitigate the risk of acute liver failure, including enhancing the immunosuppressive regimen, for those with Duchenne who are non-ambulatory," said Louise Rodino-Klapac, Ph.D., chief scientific officer and head of research & development, Sarepta. "We are deeply saddened by the loss of a second patient and extend our heartfelt condolences to the patient's family and his care team during this incredibly difficult time. Duchenne muscular dystrophy is a devastating disease that profoundly affects lives and often cuts them far too short. With more than 900 individuals treated to-date, we know how much hope families place in new treatment options like ELEVIDYS – and we are committed to honoring that hope by acting swiftly, guided by scientific rigor and the insights of leading experts, to strengthen safety for all future patients." Commitment to Long-Term Safety and Understanding Sarepta remains committed to a thorough approach and the highest standards of patient safety and scientific rigor. The event has been reported to FDA and global health authorities and will inform ongoing discussions around a potential label update to reflect the risk of severe ALF and additional immune management strategies for non-ambulatory patients. While elevated liver enzymes are a known class effect of all AAV-based gene therapies, the exact mechanism behind AAV-related liver toxicity remains unclear. Current evidence suggests it is likely driven by an adaptive immune response. The Company will provide additional updates as appropriate. Investor Conference Call Details Sarepta will be hosting a conference call and webcast to discuss this update and provide an update on the Company's business on Monday, June 16, 2025, at 8:00 am Eastern time. The event will be webcast live under the investor relations section of Sarepta's website at: and following the event a replay will be archived there for one year.

About ELEVIDYS (delandistrogene moxeparvovec-rokl) ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy – mutations or changes in the DMD gene that result in the lack of dystrophin protein – through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle. ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age. For patients who are ambulatory and have a confirmed mutation in the DMD gene For patients who are non-ambulatory and have a confirmed mutation in the DMD gene. The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). IMPORTANT SAFETY INFORMATION CONTRAINDICATION: ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene. WARNINGS AND PRECAUTIONS: Infusion-related Reactions: Infusion-related reactions, including hypersensitivity reactions and anaphylaxis, have occurred during or up to several hours following ELEVIDYS administration. Closely monitor patients during administration and for at least 3 hours after the end of infusion. If symptoms of infusion-related reactions occur, slow, or stop the infusion and give appropriate treatment. Once symptoms resolve, the infusion may be restarted at a lower rate. ELEVIDYS should be administered in a setting where treatment for infusion-related reactions is immediately available. Discontinue infusion for anaphylaxis. Acute Serious Liver Injury: Acute serious liver injury has been observed with ELEVIDYS, and administration may result in elevations of liver enzymes (such as GGT, GLDH, ALT, AST) or total bilirubin, typically seen within 8 weeks. Patients with preexisting liver impairment, chronic hepatic condition, or acute liver disease (e.g., acute hepatic viral infection) may be at higher risk of acute serious liver injury. Postpone ELEVIDYS administration in patients with acute liver disease until resolved or controlled. Prior to ELEVIDYS administration, perform liver enzyme test and monitor liver function (clinical exam, GGT, and total bilirubin) weekly for the first 3 months following ELEVIDYS infusion. Continue monitoring if clinically indicated, until results are unremarkable (normal clinical exam, GGT, and total bilirubin levels return to near baseline levels). Systemic corticosteroid treatment is recommended for patients before and after ELEVIDYS infusion. Adjust corticosteroid regimen when indicated. If acute serious liver injury is suspected, consultation with a specialist is recommended. Immune-mediated Myositis: In clinical trials, immune-mediated myositis has been observed approximately 1 month following ELEVIDYS infusion in patients with deletion mutations involving exon 8 and/or exon 9 in the DMD gene. Symptoms of severe muscle weakness, including dysphagia, dyspnea, and hypophonia, were observed. Limited data are available for ELEVIDYS treatment in patients with mutations in the DMD gene in exons 1 to 17 and/or exons 59 to 71. Patients with deletions in these regions may be at risk for a severe immune-mediated myositis reaction. Advise patients to contact a physician immediately if they experience any unexplained increased muscle pain, tenderness, or weakness, including dysphagia, dyspnea, or hypophonia, as these may be symptoms of myositis. Consider additional immunomodulatory treatment (immunosuppressants [e.g., calcineurin-inhibitor] in addition to corticosteroids) based on patient's clinical presentation and medical history if these symptoms occur. Myocarditis: Acute serious myocarditis and troponin-I elevations have been observed following ELEVIDYS infusion in clinical trials. If a patient experiences myocarditis, those with pre-existing left ventricle ejection fraction (LVEF) impairment may be at higher risk of adverse outcomes. Monitor troponin-I before ELEVIDYS infusion and weekly for the first month following infusion and continue monitoring if clinically indicated. More frequent monitoring may be warranted in the presence of cardiac symptoms, such as chest pain or shortness of breath. Advise patients to contact a physician immediately if they experience cardiac symptoms. Preexisting Immunity against AAVrh74: In AAV-vector based gene therapies, preexisting anti-AAV antibodies may impede transgene expression at desired therapeutic levels. Following treatment with ELEVIDYS, all patients developed anti-AAVrh74 antibodies. Perform baseline testing for presence of anti-AAVrh74 total binding antibodies prior to ELEVIDYS administration. ELEVIDYS administration is not recommended in patients with elevated anti-AAVrh74 total binding antibody titers greater than or equal to 1:400. Adverse Reactions: The most common adverse reactions (incidence ≥5%) reported in clinical studies were vomiting, nausea, liver injury, pyrexia, and thrombocytopenia. Report negative side effects of prescription drugs to the FDA. Visit or call 1-800-FDA-1088. You may also report side effects to Sarepta Therapeutics at 1-888-SAREPTA (1-888-727-3782).

We are taking immediate, decisive steps to better understand and mitigate the risk of acute liver failure, including enhancing the immunosuppressive regimen, for those with Duchenne who are non-ambulatory," said Louise Rodino-Klapac, Ph.D., chief scientific officer and head of research & development, Sarepta. "We are deeply saddened by the loss of a second patient and extend our heartfelt condolences to the patient's family and his care team during this incredibly difficult time. Duchenne muscular dystrophy is a devastating disease that profoundly affects lives and often cuts them far too short. With more than 900 individuals treated to-date, we know how much hope families place in new treatment options like ELEVIDYS – and we are committed to honoring that hope by acting swiftly, guided by scientific rigor and the insights of leading experts, to strengthen safety for all future patients." Commitment to Long-Term Safety and Understanding Sarepta remains committed to a thorough approach and the highest standards of patient safety and scientific rigor. The event has been reported to FDA and global health authorities and will inform ongoing discussions around a potential label update to reflect the risk of severe ALF and additional immune management strategies for non-ambulatory patients. While elevated liver enzymes are a known class effect of all AAV-based gene therapies, the exact mechanism behind AAV-related liver toxicity remains unclear. Current evidence suggests it is likely driven by an adaptive immune response. The Company will provide additional updates as appropriate.

About ELEVIDYS (delandistrogene moxeparvovec-rokl) ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy – mutations or changes in the DMD gene that result in the lack of dystrophin protein – through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle. ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age. For patients who are ambulatory and have a confirmed mutation in the DMD gene For patients who are non-ambulatory and have a confirmed mutation in the DMD gene. The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). IMPORTANT SAFETY INFORMATION CONTRAINDICATION: ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene. WARNINGS AND PRECAUTIONS: Infusion-related Reactions: Infusion-related reactions, including hypersensitivity reactions and anaphylaxis, have occurred during or up to several hours following ELEVIDYS administration. Closely monitor patients during administration and for at least 3 hours after the end of infusion. If symptoms of infusion-related reactions occur, slow, or stop the infusion and give appropriate treatment. Once symptoms resolve, the infusion may be restarted at a lower rate. ELEVIDYS should be administered in a setting where treatment for infusion-related reactions is immediately available. Discontinue infusion for anaphylaxis. Acute Serious Liver Injury: Acute serious liver injury has been observed with ELEVIDYS, and administration may result in elevations of liver enzymes (such as GGT, GLDH, ALT, AST) or total bilirubin, typically seen within 8 weeks. Patients with preexisting liver impairment, chronic hepatic condition, or acute liver disease (e.g., acute hepatic viral infection) may be at higher risk of acute serious liver injury. Postpone ELEVIDYS administration in patients with acute liver disease until resolved or controlled. Prior to ELEVIDYS administration, perform liver enzyme test and monitor liver function (clinical exam, GGT, and total bilirubin) weekly for the first 3 months following ELEVIDYS infusion. Continue monitoring if clinically indicated, until results are unremarkable (normal clinical exam, GGT, and total bilirubin levels return to near baseline levels). Systemic corticosteroid treatment is recommended for patients before and after ELEVIDYS infusion. Adjust corticosteroid regimen when indicated. If acute serious liver injury is suspected, consultation with a specialist is recommended. Immune-mediated Myositis: In clinical trials, immune-mediated myositis has been observed approximately 1 month following ELEVIDYS infusion in patients with deletion mutations involving exon 8 and/or exon 9 in the DMD gene. Symptoms of severe muscle weakness, including dysphagia, dyspnea, and hypophonia, were observed. Limited data are available for ELEVIDYS treatment in patients with mutations in the DMD gene in exons 1 to 17 and/or exons 59 to 71. Patients with deletions in these regions may be at risk for a severe immune-mediated myositis reaction. Advise patients to contact a physician immediately if they experience any unexplained increased muscle pain, tenderness, or weakness, including dysphagia, dyspnea, or hypophonia, as these may be symptoms of myositis. Consider additional immunomodulatory treatment (immunosuppressants [e.g., calcineurin-inhibitor] in addition to corticosteroids) based on patient's clinical presentation and medical history if these symptoms occur. Myocarditis: Acute serious myocarditis and troponin-I elevations have been observed following ELEVIDYS infusion in clinical trials. If a patient experiences myocarditis, those with pre-existing left ventricle ejection fraction (LVEF) impairment may be at higher risk of adverse outcomes. Monitor troponin-I before ELEVIDYS infusion and weekly for the first month following infusion and continue monitoring if clinically indicated. More frequent monitoring may be warranted in the presence of cardiac symptoms, such as chest pain or shortness of breath. Advise patients to contact a physician immediately if they experience cardiac symptoms. Preexisting Immunity against AAVrh74: In AAV-vector based gene therapies, preexisting anti-AAV antibodies may impede transgene expression at desired therapeutic levels. Following treatment with ELEVIDYS, all patients developed anti-AAVrh74 antibodies. Perform baseline testing for presence of anti-AAVrh74 total binding antibodies prior to ELEVIDYS administration. ELEVIDYS administration is not recommended in patients with elevated anti-AAVrh74 total binding antibody titers greater than or equal to 1:400. Adverse Reactions: The most common adverse reactions (incidence ≥5%) reported in clinical studies were vomiting, nausea, liver injury, pyrexia, and thrombocytopenia.
