We are a clinical-stage immuno-oncology company focused on using our specialized knowledge of the biological pathways critical to the immunosuppressive tumor microenvironment, or the TME, for the development of next-generation cancer therapies. While first-generation immuno-oncology therapies, such as checkpoint inhibitors, are a remarkable therapeutic advancement, we believe most patients do not achieve durable clinical benefit primarily because these therapies focus on only one element of the complex and interconnected immunosuppressive TME. We believe there is a significant opportunity to more broadly engage the body’s immune system in a multi-faceted, coordinated and personalized approach, to meaningfully improve cure rates for patients with a variety of cancers. Our approach is to identify key components within the TME to gain a deep understanding of its biology, leverage this understanding to define optimal therapeutic targets and the patients most likely to benefit and develop novel antibody therapeutics with differentiated biologic activity. By utilizing our specialized knowledge and expertise in immunology, oncology, antibody selection and characterization, and translational research, we have developed a broad pipeline of TME-focused programs that we believe are the next generation of immuno-oncology therapies. In January 2016, we entered into a strategic collaboration with Novartis to leverage our combined expertise and resources to develop novel immunotherapies targeting the TME.
