Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder affecting roughly 1 in 3,500 males. DMD is due to mutations in the dystrophin gene, which encodes for an exceptionally large 427 kD protein. DMD is characterized by repeated degeneration and regeneration of muscle fibers, but ultimately replacement of muscle with fibrotic and adipose tissue. Despite advances in gene therapy and improvements in quality of life, most patients still die by 30 years of age due to cardiopulmonary failure.
Sarepta Therapeutics Inc. has set the wholesale acquisition cost of the first gene transfer therapy for ambulatory patients with Duchenne muscular dystrophy at $3.2 million, making it one of the most expensive gene therapies. The company said the gross-to-net price for Elevidys (delandistrogene moxeparvovec) will be in the mid-20% range, which, suggests Mizuho Group analyst Uy Ear, would put the price at about $2.4 million.
Sarepta Therapeutics Inc. is set to introduce the first gene transfer therapy for ambulatory patients diagnosed with Duchenne muscular dystrophy (DMD), after the U.S. FDA granted accelerated approval to SRP-9001 (delandistrogene moxeparvovec). Branded Elevidys, the therapy marks Sarepta’s fourth approved treatment for DMD and the first to offer patients a one-time treatment option.
With its Duchenne muscular dystrophy (DMD) drug, vamorolone, under U.S. FDA review, Santhera Pharmaceutical AG has signed a $231 million-plus-royalties North America commercialization deal with Catalyst Pharmaceuticals Inc.
It has been a tough spring for Fibrogen Inc., which reported another phase III miss on June 7, this time for rare disease drug pamrevlumab to treat non-ambulatory patients with Duchenne muscular dystrophy (DMD).
Researchers from Huidagene Therapeutics Co. Ltd. have evaluated the effects of adenine base editing (ABE)-induced exon skipping of exon 50 in a humanized mouse model of Duchenne muscular dystrophy (DMD).
Sarepta Therapeutics Inc.’s balloting March 12 from the U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee (OTAT) in favor of gene transfer therapy SRP-9001 (delandistrogene moxeparvovec) in Duchenne muscular dystrophy (DMD) had Wall Street mulling the odds for others in the space.
The debate over Sarepta Therapeutics Inc.’s gene transfer therapy, SRP-9001 (delandistrogene moxeparvovec), in Duchenne muscular dystrophy (DMD) proved as thorny as expected during a closely watched meeting of the U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee. Panelists voted on a single question: “Do the overall considerations of benefit and risk, taking into account the existing uncertainties, support accelerated approval of SRP-9001, using as a surrogate endpoint expression of Sarepta’s microdystrophin at week 12 after administration, for the treatment of ambulatory patients with DMD with a confirmed mutation in the DMD gene?” Balloting turned out 8 yes, 6 no.
How grave they might be remains unknown, but regulatory questions have surfaced in briefing documents related to the soon-to-happen panel meeting on Sarepta Therapeutics Inc.’s gene transfer therapy delandistrogene moxeparvovec in Duchenne muscular dystrophy (DMD). The U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee will meet May 12 to discuss the compound, also known as SRP-9001.
