A phase 3 study has yielded favorable topline results for Marstacimab (HYMPAVZI), showing promising efficacy and safety in treating severe hemophilia A or B with inhibitors.
Pfizer announced the positive findings, highlighting the therapy’s potential to address an important unmet need for patients with antibodies that limit factor-based prophylaxis.
“These encouraging results demonstrate HYMPAVZI’s potential to help people living with hemophilia A or B with inhibitors, meeting an important need for patients with antibodies that neutralize most factor-based prophylactic options used to manage bleeding episodes,” commented Pfizer’s chief inflammation & immunology officer Michael Vincent, MD, PhD.
