Pfizer’s HYMPAVZI Receives FDA Priority Review to Expand Treatment to Children and Patients with Hemophilia A or B Without Inhibitors
Pfizer has reached a major regulatory milestone with the FDA granting Priority Review for HYMPAVZI™ (marstacimab) to include children as young as six and patients with hemophilia inhibitors. If approved, HYMPAVZI would become the first non-factor prophylactic treatment for children aged 6–11 with hemophilia B, offering a simplified, once-weekly injection that addresses a massive unmet medical need in the rare disease community.
