About the Inhibrx sdAb Platform

Inhibrx utilizes diverse methods of protein engineering in the construction of therapeutic candidates that can address the specific requirements of complex target and disease biology. A key tool for this effort is the Inhibrx proprietary sdAb platform, which enables the development of therapeutic candidates with attributes superior to other monoclonal antibody and fusion protein approaches. This platform enables the construction of molecules that contain multiple binding units with defined valency or multiple specificities. These novel antibodies can be combined to create therapeutic candidates with the potential to achieve enhanced cell signaling or conditional activation. Importantly, these optimized, multi-functional entities can be manufactured using the established processes that are common in the production of therapeutic proteins.
