Item 8.01 Other Events
Synthetic Biologics, Inc. (the “Company”) today issued a press release announcing positive topline data from its Phase 2b clinical trial for SYN-004 (ribaxamase), the Company’s first-in-class oral enzyme designed to protect the gut microbiome from disruption caused by certain intravenous (IV) beta-lactam antibiotics. The trial, a randomized, double-blind, placebo controlled trial of 412 patients, met its primary endpoint of significantly reducing C. difficile Infection (CDI). Preliminary analysis of the data indicates seven confirmed cases of CDI in the placebo group compared to two cases in the ribaxamase treatment group. Patients receiving ribaxamase achieved a 71.4% relative risk reduction (p-value=0.045) in CDI rates compared to patients receiving placebo. Adverse events reported during this trial were comparable between treatment and placebo arms.
Synthetic Biologics is also in the process of analyzing data from several exploratory endpoints that were designed to evaluate ribaxamase’s ability to protect the gut microbiome from colonization by opportunistic bacteria such as C. difficile and other antibiotic-resistant pathogens. Preliminary analysis of the data demonstrated a significant reduction in new colonization by vancomycin-resistant enterococci (VRE) for patients receiving ribaxamase compared to placebo (p-value=0.0002). The study included a secondary endpoint to assess ribaxamase’s capacity to decrease the incidence of antibiotic-associated diarrhea from all cases. Preliminary analysis of the data suggested a trend towards such a reduction (p-value=0.13), which was due, for the most part, to the reduction of CDI.
These data are consistent with ribaxamase’s mechanism of action designed to protect and preserve the natural balance of the gut microbiome from the unintended effects of IV antibiotic use. The Company expects to share additional results from these exploratory endpoints as they become available later this year, including results focused on ribaxamase’s ability to prevent the emergence of antimicrobial resistance in the gut microbiome.
The press release is attached as Exhibit 99.1 to this report on Form 8-K and is incorporated herein by reference.
