Alnylam and Dicerna Form RNAi Therapeutics Collaboration on Alpha-1 Antitrypsin Deficiency-Associated Liver Disease

The Life Sciences team advised Alnylam Pharmaceuticals (Nasdaq: ALNY) in its agreement with Dicerna Pharmaceuticals (Nasdaq: DRNA) to form a development and commercialization collaboration on investigational RNAi therapeutics for the treatment of alpha-1 antitrypsin (A1AT) deficiency-associated liver disease (alpha-1 liver disease). The companies also completed a cross-license of their respective intellectual property for Alnylam’s lumasiran and Dicerna’s nedosiran investigational programs for the treatment of primary hyperoxaluria (PH). These agreements will enhance and accelerate Alnylam’s and Dicerna’s ability to bring these orphan product candidates to market. The transaction related to alpha-1 liver disease is subject to the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and other customary conditions.

Under the development and commercialization agreement, Alnylam’s ALN-AAT02 and Dicerna’s DCR-A1AT, investigational RNAi therapeutics, each in Phase 1/2 development, will be explored for the treatment of alpha-1 liver disease. Under the agreement, Dicerna assumes responsibility for both ALN-AAT02 and DCR-A1AT at its cost, and may progress one or both of these investigational medicines through clinical development.

In a separate agreement, Alnylam and Dicerna granted each other a non-exclusive cross-license to their respective intellectual property related to their PH treatment investigational programs to ensure that each party has the freedom to develop and commercialize its respective product candidate: Alnylam’s lumasiran targeting glycolate oxidase (GO) for the treatment of PH type 1 and Dicerna’s nedosiran targeting lactate dehydrogenase A (LDHA) for the treatment of PH types 1, 2, and 3.

The Goodwin team was led by Shane Albright and also included Andrea Murino, Kirby Lewis and Kara Kuritz (Antitrust).
