| Manufacturing We currently manufacture our drug substance for our clinical trials at our manufacturing facilities located in Rockville, Maryland. For our antibody product candidates, we have supplemented our drug substance manufacturing capacity through an arrangement with AGC Biologics, Inc. (AGC, formerly CMC Biologics, Inc.), a contract manufacturing organization, and plan to commercially produce margetuximab at AGC assuming approval of margetuximab. We have also completed the build-out of a manufacturing suite at our headquarters building in Rockville, Maryland, which has been designed to increase our internal capacity to manufacture more drug substance lots, at larger scale and in full compliance with current Good Manufacturing Practices (cGMP) to be able to sell commercial product, when and if approved by the FDA . In addition, we currently rely on and will continue to rely on contract fill-finish service providers, primarily Ajinomoto Althea, Inc. and Baxter Healthcare Corporation, to fulfill our fill-finish needs for our current and future product candidates.
