Synthetic Biologics Provides Update on Investigator-Sponsored Phase 2b Clinical Study of SYN-010 in IBS-C Patients
Synthetic Biologics (NYSE American: SYN) announced that the Phase 2b clinical trial of SYN-010 for irritable bowel syndrome with constipation (IBS-C) will be discontinued due to an interim futility analysis conducted by Cedars-Sinai Medical Center. Although SYN-010 was well-tolerated, it is unlikely to meet its primary efficacy objective. The trial aimed to assess improvements in complete spontaneous bowel movements (CSBMs) over a 12-week period for two dosage strengths. The company remains committed to advancing its other candidates, SYN-004 and SYN-020.
- SYN-010 was well-tolerated during the Phase 2b clinical trial.
- The company plans to advance clinical trials for SYN-004 and SYN-020.
- The Phase 2b trial of SYN-010 is being discontinued due to lack of efficacy.
- SYN-010 is unlikely to meet its primary objective by the end of enrollment.
ROCKVILLE, Md., Oct. 2, 2020 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE American: SYN), a diversified clinical-stage company leveraging the microbiome to develop therapeutics designed to prevent and treat gastrointestinal ("GI") diseases in areas of high unmet need, today announced the results of a planned interim futility analysis of the investigator-sponsored Phase 2b clinical study of SYN-010 being conducted by Cedars-Sinai Medical Center ("CSMC"). Based on the review of the interim analysis, it was concluded that although SYN-010 was well-tolerated, it is unlikely to meet its primary objective by the time enrollment is completed. As a result, CSMC has agreed to discontinue the trial and will conduct a comprehensive review of the final data set and publish its findings.
The Phase 2b study was being conducted by the Medically Associated Science and Technology ("MAST") Program at CSMC and designed to evaluate two dose strengths of oral SYN-010 (21 mg and 42 mg) in patients diagnosed with irritable bowel syndrome with constipation (IBS-C). The primary objective of the study was intended to determine the efficacy of SYN-010, measured as an improvement from baseline in the weekly average number of complete spontaneous bowel movements ("CSBMs") during the 12-week treatment period for SYN-010 21 mg and 42 mg daily doses relative to placebo.
"We are grateful to the patients and Cedars-Sinai who supported this clinical trial. Although the results were disappointing for SYN-010, we remain committed to the development of new life changing medications for GI diseases" said Steven A. Shallcross, Chief Executive Officer of Synthetic Biologics. "Looking forward, we remain focused on working with our clinical development partners to advance the planned Phase 1b/2a clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant (HCT) patients, and to advance the clinical development program for SYN-020 intestinal alkaline phosphatase (IAP) in multiple potential indications."

About Irritable Bowel Syndrome
IBS affects an estimated 10 to 15 percent of the population, or as many as 45 million people in North America. The condition affects both men and women; however, two-thirds of diagnosed sufferers are women. It has been reported that up to 20 percent of all IBS patients have IBS-C and current FDA-approved therapies for the treatment of IBS-C, which include prescription and over-the-counter laxatives, do little to treat the underlying cause of the disease. These products provide patients with temporary relief from the symptoms of constipation by elevating the amount of water which passes through the gastrointestinal tract, but they tend to cause an IBS-C patient to swing from suffering from constipation, to suffering from diarrhea.
About SYN-010
SYN-010 is a proprietary, modified-release formulation of lovastatin lactone that is intended to reduce methane production by certain microorganisms (M. smithii) in the gut while minimizing disruption to the microbiome to treat an underlying cause of IBS-C. SYN-010 is intended to act primarily in the intestinal lumen while avoiding systemic absorption, thereby targeting a major cause of IBS-C, not just the symptoms.

About Synthetic Biologics, Inc.
Synthetic Biologics, Inc. (NYSE American: SYN) is a clinical-stage company leveraging the microbiome to develop therapeutics designed to prevent and treat gastrointestinal (GI) diseases in areas of high unmet need. The Company's lead clinical candidates are: (1) SYN-004 (ribaxamase) which is designed to degrade certain commonly used intravenous (IV) beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, C. difficile infection (CDI), overgrowth of pathogenic organisms, the emergence of antimicrobial resistance (AMR) and acute graft-versus-host-disease (aGVHD) in allogeneic hematopoietic cell transplant (HCT) recipients, and (2) SYN-010, which is intended to reduce the impact of methane-producing organisms in the gut microbiome to treat an underlying cause of irritable bowel syndrome with constipation (IBS-C). The Company is also advancing SYN-020, an oral formulation of the enzyme intestinal alkaline phosphatase (IAP) to treat both local GI and systemic diseases.
