Alnylam Pharmaceuticals Inc., of Cambridge, Mass., and Dicerna Pharmaceuticals Inc., of Lexington, Mass., formed 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). In addition, the companies have 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). The companies said those agreements will enhance and accelerate Alnylam’s and Dicerna’s ability to bring those orphan product candidates to market. ALN-AAT02 and Dicerna’s DCR-A1AT, investigational RNAi therapeutics, each in phase I/II development, will be explored for the treatment of alpha-1 liver disease. Dicerna assumes responsibility for both ALN-AAT02 and DCR-A1AT at its cost, and may progress one or both of those investigational medicines through clinical development. Dicerna will select which product candidate(s) to advance in development. At the completion of phase III work, Alnylam has the no-cost opportunity to opt-in to commercialize the selected candidate in countries outside the U.S., where it already has a commercialization infrastructure in place. If Alnylam exercises its opt-in right, each party will pay tiered royalties to the other party based on net product sales generated in its territory at rates dependent on which candidate is commercialized. In the event Alnylam waives its commercialization option, Dicerna will keep worldwide rights to commercialize the selected candidate(s) in exchange for milestones and royalties payable to Alnylam, also at a rate dependent on which candidate is ultimately commercialized. In a separate agreement, Alnylam and Dicerna granted each other a nonexclusive 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 candidate. Shares of Dicerna (NASDAQ:DRNA) gained $1.91, or 10.7%, to close April 6 at $19.81, while Alnylam (NASDAQ:ALNY) gained $6.32 to close at $112.14.

Assembly Biosciences Inc., of South San Francisco, said results from a research study evaluating the turnover rate of covalently closed circular DNA (cccDNA), which plays a pivotal role in the establishment and persistence of hepatitis B virus (HBV) infection, were published in Hepatology, the journal of the American Association for the Study of Liver Diseases. The study was conducted in collaboration with Nanfang Hospital, Southern Medical University in Guangzhou, China and used a molecular genetic approach to monitor the appearance and disappearance of resistance mutations as a biomarker of cccDNA turnover in longitudinal liver biopsies and serum samples obtained from patients from two clinical trials. HBV virion DNA, cccDNA and HBV pgRNA were isolated and sequenced from clinical samples. The genetic makeup of cccDNA pools were shown to turnover in as little as three to four months, consistent with frequent cccDNA replacement in chronically infected patients and suggesting that regimens which fully inhibit cccDNA replenishment may achieve a finite cure through decay of the existing cccDNA pool during treatment. Results also showed a strong correlation observed between cccDNA composition and serum pgRNA in paired liver and serum samples, suggesting that serum HBV pgRNA is a primary surrogate marker of cccDNA when liver biopsies are unavailable. Shares of Assembly (NASDAQ:ASMB) gained $1.85, or 12%, to close April 6 at $16.95.
