Somers, Ph.D., was a biotherapeutics research and development leader with more than 30 years of experience across biotechnology and pharmaceutical organizations, including Pfizer. As a scientist living with hemophilia, Dr. Somers played a key role in driving the patient-centric and purposeful design of HYMPAVZI (marstacimab-hncq). This episode will explore how the patient perspective influenced the scientific journey, with a special focus on Will's research and why it was personally important for him to bring HYMPAVZI to people with hemophilia. HYMPAVZI may cause serious side effects, including blood clots (thromboembolic events). HYMPAVZI may increase the risk for your blood to clot in blood vessels in your arm, leg, lung, or head, which can be life-threatening.
