Upon issuance, this patent will strengthen the intellectual property estate covering the use of SYN-010 for the treatment of IBS-C until at least 2034, affording the Company an extended term for commercialization.

U.S. Patent Application No. 14/776,465, which is owned by Cedars-Sinai Medical Center (CSMC) and exclusively licensed to Synthetic Biologics, is based on innovative research led by Mark Pimentel, M.D., FRCP(C), Program Director of CSMC’s Medically Associated Science and Technology (MAST) Program and Chairman of Synthetic Biologics’ IBS-C Clinical Advisory Board, which correlates methane production in the gut by certain microorganisms (M. smithii) with symptoms commonly associated with IBS-C.
