A Biologics License Application (BLA) for margetuximab for the treatment of patients with pre-treated metastatic HER2-positive breast cancer in combination with chemotherapy is under review by the U.S. Food and Drug Administration (FDA), with a Prescription Drug User Fee Act (PDUFA) goal date of December 18, 2020.“We believe that margetuximab, if approved, could become a valuable treatment option for patients living with this devastating disease,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “We are excited to partner with EVERSANA and leverage their integrated commercial services to efficiently launch margetuximab. We have been working closely with EVERSANA to fully align our commercialization strategies to educate healthcare providers and ensure patient access to margetuximab, while maintaining MacroGenics’ cash runway to fund our broader portfolio.”Jim Lang, CEO of EVERSANA, added, “We’ve built a suite of comprehensive commercial services for biopharmaceutical innovators like MacroGenics and look forward to entering this risk-sharing arrangement with MacroGenics to support the commercialization of margetuximab, if approved. Our partnership with MacroGenics puts the patient first by supporting broad market access and comprehensive patient support services. We will work closely with MacroGenics on each stage of the product launch and roll-out.”Under the terms of the agreement, MacroGenics maintains ownership of margetuximab, including all manufacturing, regulatory and development responsibilities for the product. This includes MacroGenics’ continued development of margetuximab in combination with immune checkpoint inhibitors in gastroesophageal cancer in the Phase 2/3 MAHOGANY study, as well as other ongoing studies. EVERSANA receives a co-exclusive right to conduct approved commercialization activities. EVERSANA will utilize its internal capabilities to support sales and marketing, market access, channel management services, data and analytics, medical affairs, and other patient access related services.  MacroGenics will book sales for margetuximab.  Upon the potential approval of margetuximab, EVERSANA and MacroGenics will equally share in funding EVERSANA’s commercialization expenses.

The term of the agreement is five years following the date of FDA approval, subject to predefined termination provisions.About HER2-Positive Breast Cancer
Human epidermal growth factor receptor 2 (HER2) is a protein found on the surface of some cancer cells that promotes growth and is associated with aggressive disease and poor prognosis. Approximately 15-20% of breast cancer cases are HER2-positive. Antibody-based therapies targeting HER2 have greatly improved outcomes of patients with HER2-positive breast cancer and are now standard of care in both early-and late-stage disease. However, metastatic breast cancer remains an area of unmet need and ongoing HER2 blockade is recommended for the treatment of patients with relapsed or refractory disease.About Margetuximab
Margetuximab is an Fc-engineered, monoclonal antibody that targets the HER2 oncoprotein. HER2 is expressed by tumor cells in breast, gastroesophageal and other solid tumors. Margetuximab was designed to provide HER2 blockade and has similar HER2 binding and antiproliferative effects as trastuzumab. In addition, margetuximab has been engineered to enhance the engagement of the immune system through MacroGenics’ Fc Optimization technology. Margetuximab is also being evaluated in combination with checkpoint blockade in the Phase 2/3 MAHOGANY trial for the treatment of patients with HER2-positive gastroesophageal cancer (NCT04082364), and in combination with tebotelimab (PD-1 × LAG-3 bispecific DART® molecule) in various HER2+ indications (NCT03219268).
