Pfizer’s fidanacogene elaparvovec has hit the mark in a Phase III hemophilia B trial just a month after rival UniQure’s Hemgenix won US approval, with Pfizer’s plans for regulatory action raising the stakes for Hemgenix.

While Hemgenix has courted criticism since its $3.5m price tag was unveiled, a drug pricing expert has told Scrip discounts and value-based agreements could make the therapy more palatable to payers.

Eyestem founder and CEO talks to Scrip about progress made by the firm’s experimental treatment for dry age-related macular degeneration, cell and gene therapy pricing considerations and the wider competitive landscape. The company is also developing treatments for retinitis pigmentosa and idiopathic pulmonary fibrosis.

BioMarin maintains its lead in the race to win approval for a hemophilia A gene therapy in the US by resubmitting Roctavian two years after the FDA issued a CRL in response to the original BLA.
