Pfizer’s Marstacimab Meets Phase 3 Goals
Pfizer says that its investigational hemophilia drug marstacimab met its primary endpoints in the Phase 3 BASIS trial, demonstrating statistically significant and clinically meaningful effects. A company statement says marstacimab is an investigational anti-tissue factor pathway inhibitor being studied to treat hemophilia A or B for people without inhibitors to Factor VIII or Factor IX.
“The BASIS trial demonstrated that prophylactic treatment with marstacimab resulted in a statistically significant and clinically relevant reduction in annualized bleeding rate in people living with severe hemophilia A and moderately severe to severe hemophilia B without inhibitors,” the statement says.
The company says the safety profile for marstacimab was consistent with Phase 1/2 results and treatment was generally well tolerated. No deaths were reported and there have been no thromboembolic events or events of consumptive coagulopathy recorded in patients who have been enrolled in clinical trials investigating marstacimab, Pfizer says.
