Astrazeneca plc seems on the way to expanding its presence in myasthenia gravis (MG) with positive “high-level” results from a global, randomized, double-blind, placebo-controlled phase III trial with once-weekly, self-administered gefurulimab in adults with anti-acetylcholine receptor antibody-positive, generalized disease.
In an about-face, Sarepta Therapeutics Inc. said it would “voluntarily and temporarily” pause all shipments of Duchenne muscular dystrophy gene therapy Elevidys (delandistrogene moxeparvovec) in the U.S. The move comes only a few days after the firm publicly declined a U.S. FDA request to halt shipping of the therapy in the wake of a third patient death, this one linked to a gene therapy using the same adeno-associated virus (AAV) vector as Elevidys.
Sarepta Therapeutics Inc. is declining a U.S. FDA request to voluntarily halt shipping its gene therapy, Elevidys (delandistrogene moxeparvovec), in the U.S. On July 18, Sarepta said had it received “an informal request” from the FDA to stop the shipments following a third patient’s death, tied to the gene therapy SRP-9004, which uses the same vector as Elevidys.
Sarepta Therapeutics Inc. made known a third gene therapy death, this time with SRP-9004 for limb-girdle muscular dystrophy. The patient was a late-stage, non-ambulatory 51-year-old man participating in the phase I Discovery trial, who expired about a month ago of acute liver failure, as did the two previous subjects who passed away after they were treated with Elevidys (delandistrogene moxeparvovec), Cambridge, Mass.-based Sarepta’s gene product for Duchenne muscular dystrophy.
Carving out $400 million in annual cost savings is going over well with Sarepta Therapeutics Inc.’s investors, as the company’s stock got a 19.6% boost on July 17. Its big seller, the gene therapy Elevidys (delandistrogene moxeparvovec), continued its revenue numbers decline, so Sarepta chopped operating expenses by letting about 500 employees go in a 36% cutback and pared its development path.
Capricor Therapeutics Inc. received a complete response letter (CRL) from the U.S. FDA on the BLA for deramiocel to treat cardiomyopathy in Duchenne muscular dystrophy patients. The company’s CEO said the letter was unexpected.
Ultragenyx Pharmaceutical Inc. and Mereo Biopharma Group plc, along with investors, had hoped for an early halt to the phase III study of setrusumab in treating brittle bones. They didn’t get it, as the clinical trial’s data monitoring committee wants the study to roll on through its final analysis.
In yet another fail for the Duchenne muscular dystrophy (DMD) field, Taiho Pharmaceutical Co. Ltd.’s pizuglanstat (TAS-205) did not meet the primary endpoint in a phase III trial. The phase III Reach-DMD trial, a randomized, placebo-controlled, double-blind and open-label, extension study of pizuglanstat in patients with DMD showed no significant difference in the mean change from baseline to 52 weeks in the primary endpoint of time to rise from the floor in the ambulatory cohort of the study.
An experimental drug for treating diabetes and obesity has been shown to lower blood sugar levels and increase fat burning. It is a β2-adrenergic receptor (β2AR) agonist that mimics the effects of physical exercise by activating skeletal muscle metabolism. Unlike GLP-1-based treatments such as semaglutide and tirzepatide, this new compound, developed by researchers at the Karolinska Institute, Stockholm University, and the biotech company Atrogi AB, does not suppress appetite or cause muscle loss.
Edgewise Therapeutics Inc. CEO Kevin Koch speculated that “perhaps a different environment at the FDA” from four months ago led to reviewers’ caution on sevasemten, his firm’s fast skeletal myelin inhibitor for Becker muscular dystrophy and Duchenne muscular dystrophies.
