Two days after the U.S. FDA announced approval of gene therapy Lenmeldy (atidarsagene autotemcel), making it the first treatment option for rare disease metachromatic leukodystrophy, Orchard Therapeutics and parent firm Kyowa Kirin Co. Ltd. disclosed the wholesale acquisition price of $4.25 million for the one-time treatment, which edges out hemophilia B gene therapy Hemgenix (etranacogene dezaparvovec) to become the world’s most expensive drug.
The U.S. FDA approved Orchard Therapeutics plc’s BLA for gene therapy atidarsagene autotemcel, making it the first treatment option for metachromatic leukodystrophy in the U.S. The one-time treatment, branded Lenmeldy, is indicated for children with presymptomatic late infantile, presymptomatic early juvenile or early symptomatic early juvenile disease.
Ocular gene therapy specialist Pulsesight Therapeutics SAS has launched with seed funding and is raising a series A to take forward two programs using electroporation to deliver plasmid DNA in the treatment of wet age-related macular degeneration and geographic atrophy.
The new director of the U.S. NIH, Monica Bertagnolli, has set out the prospectus for her tenure, saying she intends to apply the agency’s $47 billion per annum budget to reverse the decline in health and life expectancy in the U.S.
The European Commission approved two therapies for progressive, genetic diseases: Biogen Inc.’s Friedreich’s ataxia drug, Skyclarys (omaveloxolone), and Crispr Therapeutics AG’s CRISPR/Cas9 gene therapy for sickle cell disease and transfusion-dependent beta-thalassemia, Casgevy (exagamglogene autotemcel, exa-cel).
Regenxbio Inc. plans to file a BLA this year seeking accelerated approval for gene therapy candidate RGX-121 to treat young children with mucopolysaccharidosis type II, also known as Hunter syndrome, based on positive data from the phase I/II/III Campsiite trial, which not only hit the biomarker endpoint but also indicated potential systemic benefits.
With Adverum Biotechnologies Inc.’s preliminary safety and efficacy data made public from the ongoing Luna phase II trial testing gene therapy ixoberogene soroparvovec (ixo-vec) in wet age-related macular degeneration (AMD), Wall Street promptly began stacking the results against those of competitors. CEO Laurent Fischer pointed out that ixo-vec boasts the “highest rate of injection-free patients of any study of any program at any dose.”
A disease-modifying gene therapy for Sanfilippo syndrome type A has demonstrated reductions in heparin sulfate within cerebrospinal fluid, as well as increases in the cognitive function of young patients, arming Ultragenyx Pharmaceutical Inc. with data needed to support an accelerated BLA with the U.S. FDA.
Sangamo Therapeutics Inc.’s gene therapy for Fabry disease, isaralgagene civaparvovec (ST-920), is continuing to show promising efficacy and safety in the phase I/II study, Staar, but further ahead, the company needs to either attract a partner or secure financing to move to a registrational trial.
4DMT Molecular Therapeutics Inc. is looking ahead to phase III as positive data continue to roll out for gene therapy candidate 4D-150 in wet age-related macular degeneration (AMD), with the results from the phase II portion of the phase I/II Prism trial showing the single-shot treatment significantly reduced the need for chronic anti-VEGF injections. Presented over the weekend at the Angiogenesis, Exudation, and Degeneration 2024 Conference, results from the 24-week dose-expansion cohort, which comprised wet AMD patients with severe disease and high treatment burdens, showed patients receiving the high dose (3E10 vg/eye) had a 90% reduction in annualized anti-VEGF injection rates.
