Hympavzi (marstacimab) is a human monoclonal antibody that promotes clotting activity in patients with Hemophilia A or B by targeting an endogenous anticoagulant protein called tissue factor pathway inhibitor (TFPI). The current standard of care in Hemophilia treatment is factor intravenous infusion (in Hem A and in Hem B) or subcutaneous injection emicizumab (in Hem A only). With a novel mechanism of action, differentiated clinical outcomes, and unique dosing and administration, Hympavzi is a breakthrough in hemophilia treatment. Hympavzi is a critical launch asset with accountability to contribute to near term growth and is important to delivering on Pfizer’s purpose of developing Breakthroughs that change patient’s lives. The hemophilia landscape is poised for disruption with several new molecules either recently launched and/or imminently launching in the next couple of years. As a combined $17B market, this represents one of the largest rare disease areas and the stakes are high in the next couple of years for players to establish market leadership. It will be critical for Hympavzi to motivate patients and caregivers to act with urgency and consider switching to an new efficacious, safe, and convenient treatment. Building a robust understanding of the patient experience, including drivers and barriers of switching and treatment choice, to inform strategy, positioning, messaging, data/evidence generation will be a critical success factor for accelerating Hympavzi growth. This role reports to the Global Hympavzi Lead and will be responsible for building a comprehensive Patient Activation Strategy, including insights development, content creation, and supporting regional/local execution efforts. He/She will work cross-functionally with the global hemophilia organization including other members of the Global Hympavzi Marketing Team, Medical, and Legal. Additionally, this role will work closely with counterparts within the US Hympavzi Team, the International Commercial Office (ICO), the Emerging Markets Commercial Office (EMCO), Local Markets, and Promotional Agencies. This position requires strategic thinking and agility, proven success in establishing partnerships across multiple functions, and the ability to lead through a diverse set of stakeholders.
