Biomarin Pharmaceutical IncBioMarin's ROCTAVIAN was withdrawn from the market, a commercial setback for its gene therapy.
Nearly nine in ten EU4+UK hematologists now require longer-term efficacy data before referring patients with hemophilia A for gene therapy, according to new research from Spherix Global Insights. The 2026 Market Dynamix study of 160 hematologists across France, Germany, Italy, Spain, and the United Kingdom found that 89% of physicians need longer-term efficacy data, up 23 percentage points from 66% in 2025. Patient research shows 37% of 169 US patients with hemophilia A or B were considered good candidates for gene therapy but were not currently pursuing it, while 36% of hemophilia A patients and 24% of hemophilia B patients expressed strong interest. The findings come amid commercial setbacks including the discontinuation of BEQVEZ by Pfizer, withdrawal of ROCTAVIAN by BioMarin, and supply challenges for HEMGENIX by CSL Behring.
