The programs in our portfolio are rooted in our deep mechanistic understanding of immunobiology leading to our translational focus in the disease areas of immunology, inflammation, immuno-oncology and fibrosis. Our core portfolio currently consists of four programs at various stages of clinical and preclinical development and have the potential to meaningfully improve the lives of patients who are suffering from disease. The Gossamer strategy includes leveraging an asset-rich in-licensing environment in our core areas of focus, using our in-house expertise to maximize parallel development where target biology is relevant, and driving internal research efforts on new innovative biology in areas of high unmet need.
