About Nivalis Therapeutics, Inc.

Nivalis Therapeutics, Inc. (http://www.nivalis.com) is a pharmaceutical company that has historically been focused on the discovery and development of product candidates for patients with cystic fibrosis, or CF. The Company’s development candidates selectively target an enzyme known as S-nitrosoglutathione reductase (GSNOR). GSNOR regulates levels of an endogenous protein known as S-nitrosoglutathione, or GSNO. Depleted levels of GSNO have been associated with CF, asthma, inflammatory bowel diseases and certain cardiovascular diseases. Following recent disappointing results of a Phase 2 clinical trial of its lead product candidate, cavosonstat, in CF, Nivalis determined to not pursue the development of this compound in CF and to wind down its research and development activities while devoting its efforts to investigating and evaluating strategic alternatives.

About Alpine Immune Sciences, Inc.

Alpine Immune Sciences, Inc. was founded in 2015 and is focused on developing novel protein-based immunotherapies using its proprietary variant immunoglobulin domain (vIgD™) platform technology. The vIgD platform is designed to interact with multiple targets, including many present in the immune synapse. Alpine’s vIgDs are developed using a process known as directed evolution, which can produce proteins capable of either enhancing or diminishing an immune response and thereby may apply therapeutically to both oncology and inflammatory diseases. Alpine has also developed its transmembrane immunomodulatory protein (TIP™) technology, based on the vIgD platform, to enhance engineered cellular therapies. In October 2015, Alpine signed a worldwide research and license agreement with Kite Pharma, Inc. (NASDAQ:KITE) for up to $535 million in up front and potential milestone payments and in addition, royalties on resulting sales. The agreement allows Kite access to certain targets developed using Alpine’s TIP™ platform. For more information visit www.alpineimmunesciences.com/.
