— Data Analysis Did Not Demonstrate Statistically Significant Differences Between Treatment and Placebo Groups —
ROCKVILLE, Md., Feb. 2, 2016 /PRNewswire/ — Synthetic Biologics, Inc. (NYSE MKT: SYN), a clinical stage company focused on developing therapeutics to protect the gut microbiome, today reported independent third party analysis of the investigator-sponsored Phase 2 clinical trial that evaluated Trimesta as a treatment for relapsing-remitting multiple sclerosis (RRMS) in women (NCT00451204).
In November 2015, Synthetic Biologics disclosed its intention to conduct independent third party analysis of the Phase 2 RRMS clinical trial data for purposes of evaluating Trimesta’s potential further development. Evaluations were conducted by two independent clinical research organizations. Both the clinical and magnetic resonance imaging (MRI) results from the independent analyses did not demonstrate statistically significant differences between the Trimesta plus Copaxone treatment group compared to the Copaxone plus placebo group at either 12 or 24 months. On the basis of these findings, the Company has decided to terminate its license and clinical trial agreements relating to Trimesta with the Regents of the University of California.
Third Party Analysis of Trimesta Data from Investigator-Sponsored Phase 2 RRMS Clinical Trial (differences between the Trimesta plus Copaxone treatment group compared to the Copaxone plus placebo group):
- Annualized relapse rate at 24 months 0.17 vs. 0.25 (p=0.302)
- Annualized relapse rate at 12 months 0.13 vs. 0.19 (p=0.252)
- Brain Volumes – change from baseline in patients without enhancing lesions at baseline
- Whole brain at 12 months -0.34 vs. -0.48 (p=0.321) and 24 months -0.70 vs. -0.79 (p=0.686)
- Whole gray matter at 12 months -0.44 vs. -0.70 (p=0.130) and 24 months -0.92 vs. -0.98 (p=0.772)
- Cortical gray matter at 12 months -0.36 vs. -0.76 (p=0.071) and 24 months -0.93 vs. -1.12 (p=0.487)
- White matter at 12 months -0.18 vs. -0.15 (p=0.879) and 24 months -0.38 vs. -0.48 (p=0.713)
- Enhancing lesion volume – odds ratio (OR) for treatment effect
- OR 1.35 at 12 months (p=0.46)
- OR 1.39 at 24 months (p=0.43)
- Total T2 lesion volume – change from baseline
- 29% vs. 27% at 12 months (p=0.54)
- 25% vs. 23% at 24 months (p=0.67)
“We are disappointed with the outcome of the data analyses which did not demonstrate statistically significant treatment effects in this study,” said Jeffrey Riley, Chief Executive Officer of Synthetic Biologics. “We intend to focus the Company’s resources on its other programs, including our two Phase 2 gut microbiome programs which have both demonstrated positive topline clinical results.”
