Orum Therapeutics Inc. struck a potential $945 million (₩1.3 trillion) deal with Vertex Pharmaceuticals Inc. to discover novel degrader antibody conjugates (DAC) as targeted conditioning agents for use with gene editing, including Vertex’s gene therapy, Casgevy (exagamglogene autotemcel).
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).
Though the PDUFA date for its BLA wasn’t until March 30, 2024, Vertex Pharmaceuticals Inc. celebrated the U.S. FDA approval Jan. 16 for Casgevy (exagamglogene autotemcel), expanding use the CRISPR/Cas9 gene-edited cell therapy in patients, 12 and older, with transfusion-dependent beta-thalassemia.
The EMA has once again come in behind the U.S. FDA, granting market access to 77 new products in 2023, fewer than half the 157 approvals the FDA processed in the 11 months from January through December 2023.
Both Vertex Pharmaceuticals Inc.’s Casgevy (exagamglogene autotemcel, exa-cel) and Bluebird Bio Inc.’s Lyfgenia (lovotibeglogene autotemcel, lovo-cel) received U.S. FDA approval Dec. 8, providing 16,000 American sickle cell patients who have recurring vaso-occlusive events with access to the first cell-based gene therapies.
With a landmark U.K. approval in hand for Casgevy (exagamglogene autotemcel [exa-cel]) to treat sickle cell disease and transfusion-dependent beta thalassemia, Crispr Therapeutics AG and partner Vertex Therapeutics Inc. are turning their attention to the PDUFA dates set by the U.S. FDA for the treatment in both conditions.
Had it been asked to, the FDA’s Cellular, Tissue and Gene Therapies Advisory Committee would have voted Oct. 31 to recommend approval of Vertex Pharmaceutical Inc. and Crispr Therapeutics AG’s exagamglogene autotemcel, or exa-cel, as a one-time transformative treatment for severe sickle cell disease in individuals 12 and older.
It’s just a discussion next week of Vertex Pharmaceuticals Inc. and Crispr Therapeutics AG’s sickle cell disease (SCD) therapy, with no vote expected from the U.S. FDA’s Cellular, Tissue and Gene Therapies Advisory Committee. The FDA isn’t questioning the drug’s efficacy as much as it is concerned about the effects of off-target editing.
Somatic human genome editing has made huge strides in the past five years, but the likely extremely high prices will be unsustainable. A global commitment to affordable, equitable access is urgently needed because the costs and infrastructure needs of this form of treatment are not manageable for either patients or health care systems.
CRISPR-based cell therapies continued to gain steam Sept. 27 with the announcements of a potentially valuable big pharma collaboration and an ambitious global regulatory push.
