For Immediate Release
Rockville, MD, August 8, 2019 – Synthetic Biologics, Inc. (NYSE American: SYN), a late-stage clinical company developing therapeutics that preserve the microbiome to protect and restore the health of patients, today provided an operational update and reported financial results for the three months ended June 30, 2019. The Company also announced today a clinical trial agreement with Washington University School of Medicine in St. Louis (“Washington University") to conduct a Phase 1b/2a clinical trial of SYN-004 (ribaxamase), with enrollment expected to begin in the first quarter of 2020.
“Our clinical trial collaboration with Washington University is an important step in our pursuit of a more cost-effective development strategy for SYN-004 targeting a more specialized patient population,” stated Steven A. Shallcross, Chief Executive and Financial Officer. “SYN-004’s unique mechanism of action designed to degrade intravenous (IV) beta-lactam antibiotics and prevent dysbiosis of the gut microbiome has the potential to significantly improve outcomes for patients who undergo allogeneic hematopoietic cell transplantation (HCT), an area of significant unmet medical need.”
“Prompt initiation of broad-spectrum IV beta-lactam antibiotics at onset of fever after conditioning chemotherapy for allogenic HCT is a life-saving intervention. However, this causes significant disruption of the microbiome, which places these patients at very high risk for infection due to some of our greatest antibiotic resistant threats, such as Clostridioides difficile, vancomycin-resistant Enterococci (VRE), and multidrug-resistant Gram-negative bacteria. We are seeking to determine if coadministration of SYN-004 while the patient is receiving IV beta-lactam antibiotics will preserve the microbiome and thus mitigate the risk from these threats,” said Dr. Erik R. Dubberke Professor of Medicine and Clinical Director, Transplant Infectious Diseases at Washington University. “There are data to suggest preservation of the microbiome in allogeneic HCT recipients results in improved immune function after HCT as well. This would further enhance these patients’ outcomes and quality of life.”
Mr. Shallcross continued, “During the second quarter, we remained focused on executing our strategy to advance our portfolio of gastrointestinal (GI) and microbiome-focused clinical programs. We held a highly informative pre-IND meeting with the U.S. Food and Drug Administration (FDA) for our SYN-020 intestinal alkaline phosphatase (IAP) program and clarified the parameters for IND-enabling toxicology studies. These activities are ongoing and will support our anticipated Investigational New Drug (IND) application which we intend to file promptly during the first quarter of 2020.” Mr. Shallcross concluded, “Interest from prospective patients in our investigator-sponsored Phase 2b clinical trial of SYN-010 in breath-methane positive irritable bowel syndrome with constipation (IBS-C) patients remains strong. However, after consulting with the investigators at Cedars-Sinai Medical Center, the study sponsor, enrollment has been extended to accommodate higher than anticipated screen-fail rates. This is, in part, due to errant laxative use during the screening period that adversely impacts baseline measurements of IBS-C symptoms and breath-methane levels. Rigorous screening and reliable baseline parameters are critical to all IBS-C clinical trials in order to ensure the possibility of generating a meaningful data set of the highest quality. At this time, we are discussing with Cedars-Sinai the opportunity for a data read out in the first half of 2020, extending our previous guidance from the fourth quarter of 2019. We look forward to sharing important updates and progress for this and all our GI and microbiome-focused clinical programs.”

Quarter Ended June 30, 2019 Financial Results
General and administrative expenses decreased by 27% to $1.0 million for the three months ended June 30, 2019, from $1.4 million for the three months ended June 30, 2018. This decrease is primarily due to decreased stock-based compensation expense related to forfeitures and decreased options grants, along with the reduction of investor relations and consulting costs. The charge related to stock-based compensation expense was $59,000 for the three months ended June 30, 2019, compared to $264,000 the three months ended June 30, 2018.
Research and development expenses decreased by 27% to $2.6 million for the three months ended June 30, 2019, from $3.6 million for the three months ended June 30, 2018. This decrease is primarily the result of lower SYN-004 (ribaxamase) indirect program costs for the three months ended June 30, 2019, including salary and related expense reductions resulting from the 2018 restructuring and the fact that no clinical trial activity for SYN-004 (ribaxamase) was ongoing during the quarter, offset by an increase in manufacturing costs for SYN-020. The research and development costs incurred during the quarter were primarily related to the investigator-sponsored Phase 2b clinical study of SYN-010, a potential Phase 1b/2a clinical trial of SYN-004 (ribaxamase) in allogeneic HCT recipients, and the continued development of SYN-020. Research and development expenses also include a charge relating to stock-based compensation expense of $31,000 for the three months ended June 30, 2019, compared to $293,000 for the three months ended June 30, 2018.
Other income was $80,000 for the three months ended June 30, 2019, compared to other income of $789,000 for the three months ended June 30, 2018. Other income for the three months ended June 30, 2019 is primarily comprised of interest income while the three months ended June 30, 2018 is comprised of non-cash income of $783,000 from the change in fair value of warrants. The decrease in the fair value of the warrants was due to the decrease in our stock price.
Cash and cash equivalents as of June 30, 2019 was $21.7 million, a decrease of $7.2 million from December 31, 2018.
