Wall Street was weighing the gravity of the death from acute liver failure of a patient who was treated for Duchenne muscular dystrophy (DMD) with Sarepta Therapeutics Inc.’s gene therapy, Elevidys (delandistrogene moxeparvovec). Liver injury is a known possible side effect of the product, first approved by the U.S. FDA in June 2023 for DMD, as well as other AAV-mediated gene therapies, and the potential problem is highlighted in Elevidys’ prescribing information.
While data on functional endpoints are still to come, Avidity Biosciences Inc. executives said the firm is moving ahead with plans for a BLA filing by the end of 2025 for del-zota, an antibody-oligonucleotide conjugate, in Duchenne muscular dystrophy with mutations amenable to exon 44 skipping (DMD44), based on positive top-line data that analysts say bode well for Avidity’s other late-stage programs targeting rare neuromuscular diseases.
The pairing of Mallinckrodt plc and Endo Inc. is expected to create a pharma heavyweight that will generate $3.6 billion in 2025 revenue after the duo combines their generic pharmaceuticals businesses and Endo’s sterile injectables setup. Terms call for Dublin-based Endo shareholders to collect $80 million in cash and own 49.9% of the combined firm. Owners of stock in Mallinckrodt will hold the rest of the new entity in the arrangement, which bears an enterprise value of $6.7 billion and is expected to close in the second half of this year.
Celltrion Inc. is on a biosimilar roll with the U.S. FDA this month, having gained clearance of Stoboclo and Osenvelt as products referencing Amgen Inc.’s biologic, denosumab (Prolia, Xgeva), along with Omlyclo becoming the first and only interchangeable biosimilar to omalizumab (Xolair, Genentech Inc. and Novartis AG).
Qyuns Therapeutics Co. Ltd.’s monoclonal antibody targeting IL-17A, QX-002N, met both primary and secondary endpoints in a phase III trial in ankylosing spondylitis.
Pepgen Inc. seems to have gained a leg up on competitors in early data with PGN-EDODM1 in myotonic dystrophy type 1 (DM1), and shares of the Boston-based firm (NASDAQ:PEPG) closed Feb. 24 at $2.29, up 92 cents, or about 67%. The company unveiled initial positive data from the 5- and 10-mg/kg dose cohorts in the ongoing Freedom-DM1 phase I study with PGN-EDODM1, which deploys Boston-based Pepgen’s Enhanced Delivery Oligonucleotide technology to deliver a therapeutic oligonucleotide that is designed to restore the normal function of MBNL1, a key RNA splicing protein.
Solid Biosciences Inc. is preparing for a sit-down with the U.S. FDA this year to discuss the firm’s results with the next-generation gene therapy SGT-003 for Duchenne muscular dystrophy (DMD).
The first successful phase II trial in Duchenne muscular dystrophy (DMD) heart disease rolled out from Cumberland Pharmaceuticals Inc., which said top-line findings from the experiment called Fight DMD showed promising results in the indication that represents the main cause of death for such patients.
Alterity Therapeutics Ltd. reported positive top-line phase II results for lead candidate ATH-434 for treating multiple system atrophy, a rare neurological disorder similar to Parkinson's disease.
Positive data for Veru Inc.’s enobosarm lend more weight to the potential progress of the company’s body-mass preservation program in patients taking Wegovy (semaglutide). The side effect of lean mass loss has dogged those taking GLP-1s. The study results didn’t support the company’s stock on the day of the data release as it had the previous four weeks.
