U.S. patent issued covering Trimesta (combination of Estriol and Copaxone® for multiple sclerosis) from 05/04/13 and for 14 years.
Synthetic Biologics, Inc, a developer of synthetic biologics and innovative medicines for serious infections and diseases, announced today that the U.S. Patent & Trademark Office has issued U.S. Patent No. 8,372,826 entitled, Estriol Therapy for Multiple Sclerosis and Other Autoimmune Diseases, to the Regents of the University of California which includes claims to the use of the Company's drug candidate, Trimesta™ (oral estriol), in combination with glatiramer acetate injection Copaxone®. Copaxone® is the number one selling drug for multiple sclerosis with approximately $4 billion in annual sales. Currently marketed exclusively by Teva Pharmaceutical Industries Ltd., Copaxone® is expected to face generic competition as certain patent terms begin to expire in 2014. Through its wholly owned subsidiary, Synthetic Biologics holds the exclusive worldwide license to U.S. Patent 8,372,826 and 6,936,599 and pending patents for multiple sclerosis and other autoimmune diseases covering the uses of its drug candidate, Trimesta™.
Trimesta™ is currently being utilized in combination with Copaxone® in a randomized, double-blind, placebo-controlled Phase II clinical trial for the treatment of relapsing-remitting multiple sclerosis in women. Lead Principal investigator, Rhonda Voskuhl, M.D., Director, University of California, Los Angeles (UCLA) Multiple Sclerosis Program, UCLA Department of Neurology, along with investigators at 14 other centers in the U.S., are administering either Trimesta™ (8 milligrams orally per day) in combination with Copaxone® (20 milligrams per day), or a placebo plus Copaxone® to patients enrolled in the trial.
"The claims in this new patent further expand Synthetic Biologics' coverage of our proprietary oral estriol product candidate, Trimesta™, to include its use in combination with the leading FDA-approved multiple sclerosis drug, Copaxone®," stated Jeffrey Riley, Chief Executive Officer at Synthetic Biologics. "We look forward to reporting the clinical results of this combination therapy after the relapsing-remitting multiple sclerosis patients complete their two years of dosing and monitoring scheduled for January 2014."
