ROCKVILLE, Md., April 30, 2014 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE MKT: SYN), a developer of novel anti-infective biologic and drug candidates targeting specific pathogens that cause serious infections and diseases,will host a conference call today to discuss in further detail the topline Phase II study results of Trimesta™ (oral estriol), which the Company is developing as a once-daily adjunctive oral treatment for relapsing-remitting multiple sclerosis (RRMS) in women. Topline data were announced yesterday by the University of California, Los Angeles (UCLA) School of Medicine and presented at the 66th Annual Meeting of the American Academy of Neurology by the study's lead investigator, Rhonda Voskuhl, M.D., Professor, Department of Neurology, Jack H. Skirball Chair in Multiple Sclerosis Research and Director, Multiple Sclerosis Program at UCLA David Geffen School of Medicine.
In this Phase II study, women receiving oral Trimesta plus injectable Copaxone® demonstrated a statistically significant 47 percent decrease in annualized MS relapse rate in the first 12 months of treatment compared to women receiving placebo plus Copaxone (p=0.0306), and a 32 percent decrease in annualized relapse rate at 24 months (p=0.1527). Patients in both treatment arms demonstrated improved scores on the Expanded Disability Status Scale (EDSS) compared to baseline. Cognitive function test scores, as measured by the Paced Auditory Serial Addition Test (PASAT), in women receiving Trimesta plus Copaxone also improved compared to baseline and were significantly different from placebo plus Copaxone at 12 months.
Treatment was generally safe and well tolerated. There were 21 serious adverse events (9 in the Trimesta plus Copaxone group and 12 in the placebo plus Copaxone group). Adverse events were typically mild in nature and balanced between treatment groups except for an increase in irregular menses in patients who received Trimesta.
The investigator-initiated, Phase II, two-year, multi-center, randomized, double-blinded, placebo-controlled (1:1) study evaluated Trimesta as an oral, once-daily dose of 8 mg per day plus Copaxone in women with RRMS, aged 18-50 years. At randomization, of the 158 women enrolled across 16 clinical sites in the United States, 99.4 percent had at least one relapse in the preceding 24 months.
Dr. Voskuhl's work is supported by grants exceeding $8 million, awarded primarily by the National Multiple Sclerosis Society (NMSS) in partnership with the NMSS's Southern California chapter, and the National Institutes of Health (NIH). UCLA and the NIH issued concurrent press releases April 29, 2014.
Jeffrey Riley, Chief Executive Officer, and Joe Sliman, Senior Vice President, Clinical & Regulatory Affairs, of Synthetic Biologics, Inc. will host a conference call to discuss in further detail the topline Phase II study results of Trimesta™ (oral estriol).
