Profile
From SEC filingsCompany description
A. Overview We are a clinical-stage biopharmaceutical company focused on discovering and developing engineered antibody therapeutics to treat patients with cancer and autoimmune diseases, who have unmet medical needs. We use our protein engineering capabilities to design new technologies and XmAb ® drug candidates with improved properties and multi-target mechanisms of action. We advance these candidates into clinical-stage development, where we are conducting Phase 1 and Phase 2 studies for a broad portfolio of programs, to determine which programs to advance into later stages of development and potentially commercialization, which programs we partner to optimize development, and which programs we discontinue. Our approach to protein design includes engineering Fc domains, the parts of antibodies that interact with multiple segments of the immune system and control antibody structure. The Fc domain is constant and interchangeable across antibodies, and our engineered Fc domains can be readily substituted for natural Fc domains. These Fc domains provide specific features such as bispecific structure and extended half-life and serve as the scaffolds for our XmAb drug candidates. We and our partners develop XmAb antibodies and other types of biotherapeutic drug candidates with improved properties and functionality, which can provide innovative approaches to potentially treating disease and clinical benefits over other treatment options.
