Our partnerships


In June 2020, we entered into an option and license agreement with AbbVie, which granted AbbVie the option to license worldwide rights to acazicolcept (ALPN-101), a first-in-class dual CD28/ICOS costimulation antagonist, building on AbbVie’s commitment to developing novel therapies in Immunology. During the option period, we will conduct a phase 2 study in systemic lupus erythematosus. Upon exercise of the option, AbbVie will conduct all future clinical development, manufacturing, and commercialization activities for acazicolcept. Under the terms of the agreement, we received an upfront payment of $60 million and to date have received $45 million in pre-option development milestones. As a result of the December 2023 amendment, we will be eligible to receive up to an additional $501.25 million for exercise of the option and achievement of success-based development, regulatory, and commercial milestones. In addition, we are eligible to receive tiered royalties on net sales of acazicolcept. 

Adaptimmune Therapeutics

In May 2019, we entered into a collaboration and license agreement with Adaptimmune Therapeutics to develop next-generation SPEAR™ T-cell products which incorporate our secreted and transmembrane immunomodulatory protein (termed SIP™ and TIP™) technology. Together, our companies will collaborate on a number of programs to develop SIP and TIP candidates with tailored affinities and modulatory activities potentially enhancing the anti-tumor responses seen with Adaptimmune’s SPEAR™ T-cells. For each program, Adaptimmune has an option to take a worldwide exclusive license for development and commercialization of SPEAR™ T-cell products incorporating our SIP or TIP technology for the treatment of cancer. We received an upfront payment and Adaptimmune will provide research funding for ongoing programs. In addition, there are potential downstream development and commercialization milestones up to $288 million, if all pre-specified milestones for each program are achieved and low-single digit royalties on worldwide net sales of the applicable products.

Amgen/Horizon Therapeutics plc

In December 2021, we entered into a license and collaboration agreement with Horizon Therapeutics plc for the development and commercialization of up to four preclinical candidates generated from Alpine’s unique discovery platform. We will advance candidate molecules to pre-defined preclinical milestones and then Horizon will assume responsibility for development and commercialization activities and costs.

Under the terms of the agreement, we will receive an upfront payment of $25 million as well as an equity investment of $15 million at a 25 percent premium to the 30-day volume-weighted average share price. In addition, we are eligible to receive up to $381 million per program, or approximately $1.52 billion in total, in future success-based payments related to development, regulatory and commercial milestones as well as tiered royalties on global net sales.

Join us in the discovery and development of next-generation immunotherapies.
