BOULDER, Colo. and SEATTLE, Wash., April 18, 2017 –Nivalis Therapeutics, Inc. (NASDAQ:NVLS) and Alpine Immune Sciences, Inc., a privately-held biotechnology company developing novel therapies using its next-generation immune system modulation platform, today jointly announced they have entered into a definitive merger agreement under which Alpine will merge with a wholly-owned subsidiary of Nivalis in an all-stock transaction. The merger will result in a combined company with a novel protein-based discovery platform focused on inflammation and immuno-oncology.

Alpine is focused on developing novel protein‐based therapies using its variant immunoglobulin domain (vIgD™) platform technology. The vIgD platform is designed to create novel therapeutics that modulate multiple therapeutic targets, including many present in the immune synapse. Alpine’s vIgDs are developed via a unique process known as directed evolution which can produce proteins capable of either enhancing or diminishing an immune response, creating a platform applicable to both oncology and inflammatory diseases. Alpine plans to initiate a Phase 1 clinical trial with its first compound, a dual ICOS/CD28 antagonist engineered for use in autoimmune and inflammatory diseases, in the second half of 2018.

“We believe this transaction with Alpine is an exciting path forward to advance important new therapies for patients and to create significant value for shareholders,” said Howard Furst, Chairman of the Board of Nivalis. “Alpine, which has discovered novel ways to target the immune synapse, is led by a solid and experienced management team that has successfully brought immunotherapies to market.”

“This merger provides a unique opportunity to accelerate the development of our novel immunotherapy platform focused on both inflammation and immuno-oncology,” said Mitchell H. Gold, M.D., Executive Chairman and Chief Executive Officer of Alpine Immune Sciences. “We look forward to building on our early success by taking multiple novel programs into the clinic to help patients with significant medical needs.”

Nivalis’ financial advisor for the transaction is Ladenburg Thalmann & Co. Inc., and Nivalis’ legal advisors are Latham & Watkins LLP and Ballard Spahr LLP. Alpine’s legal advisors are Sidley Austin LLP and Ascent Law Partners LLP.

About the Proposed Transaction

On January 3, 2017, Nivalis announced the initiation of a process to explore and review a range of strategic alternatives focused on maximizing stockholder value from its clinical assets and cash resources. As part of that process, bids were solicited from interested parties and over eighty interested parties submitted a proposal to enter into a strategic transaction with Nivalis. After a thorough review of each alternative and extensive negotiation with Alpine Immune Sciences, Nivalis’ board of directors unanimously decided to approve and enter into a definitive merger agreement with Alpine.

Frazier Healthcare Partners, Alpine BioVentures, and OrbiMed Advisors will invest a combined additional $17 million into Alpine Immune Sciences prior to the close of the transaction based on a valuation of Alpine which is consistent with that used to calculate the exchange ratio under the merger agreement. Following the merger, current Alpine shareholders will own approximately 74 percent of the combined company and current Nivalis shareholders will own approximately 26 percent of the combined company. The exchange ratio is based on a valuation of Nivalis equal to $50 million, which includes approximately $44 million in cash expected to be held by Nivalis at the time of closing. The combined company is expected to have approximately $90 million in cash and cash equivalents at the closing of the transaction.

The transaction has been approved by the board of directors of both companies. The merger is expected to close in the third quarter of 2017, subject to the approval of the stockholders of each company and the satisfaction or waiver of other customary conditions.

Management and Organization

Mitchell H. Gold, M.D., Alpine’s Executive Chairman and Chief Executive Officer, will become the Chairman and Chief Executive Officer of the combined company. Following the merger, the board of directors of the combined company will expand to seven seats with two representatives from Nivalis.

Upon closing of the transaction, the name of the combined company will become Alpine Immune Sciences, Inc. and shares of the combined company’s common stock will trade on the NASDAQ Global Market.

Dr. Gold and R. Michael Carruthers, interim president and chief financial officer of Nivalis, will host a conference call and simultaneous webcast to discuss the proposed transaction on April 18, 2017, at 4:30 p.m. Eastern Time.

About Nivalis Therapeutics, Inc.

Nivalis Therapeutics, Inc. ( 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 unique 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
