Capricor advances amid mixed HOPE-3 data and FDA review

Capricor Therapeutics posted Q2 2026 results with no revenue, cash about $237.9 million, and a net loss of roughly $40.7 million; HOPE-3 data published in The Lancet showed a statistically significant slowing of upper limb disease progression, while an FDA advisory committee split (3 in favor, 9 against) on Deramiocel’s effectiveness for DMD cardiomyopathy left regulatory questions. The company’s BLA remains under FDA review, manufacturing readiness is advancing, and ongoing NS Pharma dispute and a Form 483 from an FDA inspection are being addressed. Capricor projects a cash runway of at least 12 months and will provide updates as regulatory clarity emerges, with regulatory engagement in Europe/Japan and a focus on expanding to younger DMD patients and Becker muscular dystrophy; other programs are on hold pending clarity.

Telomere Protein TRF2 Drives Muscle Regeneration

A University of Pennsylvania study shows TRF2, a protein long known for protecting chromosome ends, also helps muscle stem cells maintain their identity and coordinate the repair cycle. Removing TRF2 in mouse muscle stem cells impairs regeneration, causing fat and scar tissue to accumulate after injury, and accelerates Duchenne muscular dystrophy in a mouse model. TRF2 acts beyond telomeres, targeting regulatory genome regions containing G-quadruplex structures to preserve stem cell identity, with implications for therapies and cancer biology.

Regenxbio hits milestone in Duchenne gene therapy ahead of FDA filing

Regenxbio announced its experimental Duchenne muscular dystrophy gene therapy produced sufficient levels of a miniaturized muscle protein in a clinical trial, paving the way for an FDA submission and aiming to improve on Sarepta’s Elevidys in both efficacy and safety, amid ongoing safety concerns surrounding the competitor.

Entrada's DMD readout underwhelms, sparking a sharp stock slide

Entrada Therapeutics' first readout for ENTR-601-44 in Duchenne muscular dystrophy showed a 2.36% dystrophin increase over baseline 4%, well below analysts' 10–14% targets and rival del-zota's ~25%, triggering a roughly 59% drop in the stock to $6.57. Management attributed the miss to lower-than-expected plasma exposure in juvenile DMD patients (about 50% of adult exposure). New juvenile NHP data hint at a nonlinear exon-skipping response at higher levels, suggesting the second dose cohort could see a disproportionate jump in exon skipping. The company plans a third dose cohort and a higher-dose readout in Q4 to gauge whether ENTR-601-44 can rebound.

Doug Ingram to retire as Sarepta exits turbulent Duchenne era

Sarepta Therapeutics said CEO Doug Ingram will retire by year-end after a decade in which he steered the company to three Duchenne drug approvals and a peak value around $15 billion, followed by a downturn as safety concerns around its gene therapy and the rise of superior rivals weighed on the stock; Ingram cited family health reasons—his wife and son were diagnosed with myotonic dystrophy—and Sarepta is searching for a successor.

ELEVIDYS Slows Duchenne Progression in Three-Year EMBARK Results

Sarepta reports three-year topline results from EMBARK showing ELEVIDYS significantly slows disease progression in ambulatory Duchenne patients treated at ages 4–7. By year 3, NSAA remained above baseline, with a 73% slowing of progression by Time to Rise and a 70% slowing by 10-meter walk/run versus a pre-specified external control; safety signals align with prior data, including a boxed warning for acute liver injury and related risks, with no new safety concerns observed.

Capricor Advances Deramiocel BLA: FDA Seeks Full HOPE-3 CSR

FDA has requested the full HOPE-3 clinical study report (CSR) and supporting data to address Capricor’s Complete Response Letter for the Deramiocel BLA; Capricor will submit the CSR and updates in February 2026 to support continued FDA review and a new PDUFA date, following HOPE-3 topline data showing significant skeletal muscle and cardiac improvements in Duchenne muscular dystrophy.

Sarepta Shares Plunge Amidst Study Failures and Earnings Challenges

Sarepta Therapeutics' stock plummeted by over a third after reporting mixed Q3 results, including two drug failures and delayed test outcomes, despite strong sales of its gene therapy Elevidys. The company plans to seek traditional FDA approval for Amondys 45 and Vyondys 53, but uncertainties around regulatory and reimbursement issues persist. Meanwhile, sales of Elevidys exceeded expectations, though the outlook remains uncertain amid regulatory and demand challenges.

Sarepta Shares Surge as FDA Approves Resumption of Elevidys Shipments

Sarepta Therapeutics' shares rebounded after the FDA approved the resumption of shipments for its gene therapy Elevidys in the US for ambulatory patients with Duchenne muscular dystrophy, easing concerns about liquidity and market withdrawal, though shipments for non-ambulatory patients remain halted following recent deaths and regulatory scrutiny.
