SYN-004 to Target C. difficile Infection Prevention

 

C. difficile: Acquisition of Clinical-Stage Program

In November 2012, Synthetic Biologics acquired a series of oral beta-lactamase enzymes (P1A, P2A and P3A) and related assets targeting the prevention of C. difficile infection (CDI), the leading cause of HAIs that generally occurs secondary to treatment with IV antibiotics. The acquired assets include a pre-IND package for P3A (SYN-004), Phase I and Phase II clinical data for P1A, manufacturing processes and data, and a portfolio of issued and pending U.S. and international patents intended to support an IND and Biologics License Application (BLA) with the FDA. Utilizing this portfolio of assets, Synthetic Biologics intends to develop a proprietary oral beta-lactamase enzyme product candidate, SYN-004, previously known as P3A. When co-administered with certain IV beta-lactam antibiotics, it is expected that SYN-004 can degrade the antibiotic that is excreted in the GI tract, thus preserving the natural balance of the patient's microflora, and preventing opportunistic infections including CDI. Beta-lactam antibiotics are a mainstay in hospital infection management and include the commonly used penicillin and cephalosporin classes of antibiotics. Approximately 14.4 million patients are administered "SYN-004 target" IV beta-lactam antibiotics annually, representing an estimated target market for SYN-004 of 117.6 million beta-lactam doses purchased by U.S. hospitals. The addressable market is significant and currently there are no approved treatments designed to protect the microbiome from the damaging effects of IV antibiotics. This worldwide opportunity could represent a multi-billion dollar market.*

C. difficile: Oral Enzyme Background

Synthetic Biologics acquired a series of oral beta-lactamase enzymes. Beta-lactamase enzymes have the ability to degrade beta-lactam antibiotics that may be excreted into the GI tract. P1A (the first generation candidate) showed acceptable safety and tolerability in a Phase I study. In addition, two Phase II clinical studies demonstrated that P1A had the ability to preserve GI microflora in hospitalized patients treated with intravenous ampicillin or the combination of piperacillin and tazobactam.
