Synthetic Biologics Reports Third Quarter 2018 Operational Highlights and Financial Results

ROCKVILLE, Md., Nov. 8, 2018 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE American: SYN), a late-stage clinical company developing therapeutics designed to preserve the microbiome to protect and restore the health of patients, today provided an operational update and reported financial results for the three and nine months ended September 30, 2018.

“During the third quarter, we remained sharply focused on the advancement of our portfolio of microbiome-focused assets,” stated Steven A. Shallcross, Interim Chief Executive Officer and Chief Financial Officer. “We were pleased to report the expansion of our relationship with Cedars-Sinai Medical Center and announced a research agreement to co-fund an investigator-sponsored Phase 2b clinical study of SYN-010, our modified-release formulation of lovastatin lactone designed to treat an underlying cause of irritable bowel syndrome with constipation (IBS-C). In addition to fortifying the well-established clinical data set for SYN-010, we believe results from this study will determine the optimal dose of SYN-010 for future registration studies. During the third quarter we also held an End of Phase 2 meeting with the FDA to define a clear and achievable pathway forward for SYN-004, our first-in-class therapeutic intervention designed to protect the gut microbiome from antibiotic-mediated dysbiosis. We also announced that we are evaluating opportunities that may further unlock the potential of SYN-004 through the pursuit of a second more focused indication in a specialty patient population with multiple potential disease endpoints associated with IV beta-lactam-induced gut microbiome damage, such as allogeneic hematopoietic cell transplant (HCT) recipients. This dual approach may enable us to continue the clinical advancement of SYN-004 in a cost-effective manner while targeting an area of clear unmet need and expanding upon the established data set to further validate SYN-004’s use in the broader indication for the prevention of CDI.”

Mr. Shallcross continued, “While remaining keenly focused on the execution of our clinical development activities, we also significantly strengthened our balance sheet by raising gross proceeds of approximately $18.6 million from the closing of a public offering of common stock and Series B convertible preferred stock, as well as net proceeds of approximately $11.8 million from the utilization of our “at-the-market” facility through October. As a result of these activities, our current cash position to date is approximately $32 million and should provide ample runway to allow the Company to continue its operations into 2020 as we continue to focus on the achievement of key clinical development milestones for our two-lead assets.”

Clinical Development and Operational Update

• Entered into agreement with Cedars-Sinai Medical Center (CSMC) in Q3 2018 to co-fund an investigator-sponsored Phase 2b clinical study of SYN-010 to evaluate SYN-010 dose response and inform Phase 3 clinical development:
  
  • The Phase 2b clinical study will be conducted out of the Pimentel Laboratory at CSMC and is expected to be comprised of a 12-week, placebo-controlled, double-blind, randomized clinical trial to evaluate two dose strengths of oral SYN-010 (21 mg and 42 mg) in approximately 150 patients diagnosed with IBS-C,
    
  • Anticipate dosing first patient in the Phase 2b investigator-sponsored clinical study during Q4 2018, contingent upon approval of the clinical study protocol by the Cedars-Sinai Medical Center Institutional Review Board,
    
  • Anticipate data readout from the Phase 2b investigator-sponsored clinical study during 2H 2019;
    
• Held End-of-Phase 2 meeting with the FDA to solidify the remaining elements of the SYN-004 (ribaxamase) Phase 3 clinical trial in Q3 2018;
  
• Clarified market/partner needs and identified potential additional indications for SYN-004 in specialty patient populations such as allogeneic hematopoietic cell transplant patients in 3Q 2018;
  
• Plan to initiate clinical trial(s) (2H 2019), which may include a broad Phase 3 clinical trial and/or Phase 1/2 clinical trial(s) in a specialty population leading to a subsequent Phase 3 clinical trial;
  
• Identified three potential clinical indications for SYN-020 (intestinal alkaline phosphatase) in areas of unmet medical need including, enterocolitis associated with radiation therapy, enterocolitis associated with checkpoint inhibitor therapy for cancer, and microscopic colitis in 3Q 2018,
  
  • Anticipated IND filing during Q4 2019;
    
• Strengthened balance sheet by raising gross proceeds of approximately $18.6 million from the closing of a public offering of common stock and Series B convertible preferred stock in support of the continued advancement of our microbiome-focused clinical programs in Q4 2018.

Quarter Ended September 30, 2018 Financial Results

General and administrative expenses decreased by 12% to $1.5 million for the three months ended September 30, 2018, from $1.7 million for the three months ended September 30, 2017. This decrease is primarily the result of lower salary expense, stock compensation, and related benefits costs incurred during the three months ended September 30, 2018 as compared to the three months ended September 30, 2017 due to the resignation of the prior Chief Executive Officer, along with the reduction of travel and consulting expense, offset by higher registration, investor relations and legal costs. The charge related to stock-based compensation expense was $186,000 for the three months ended September 30, 2018, compared to $583,000 the three months ended September 30, 2017.

Research and development expenses decreased by 32% to $2.8 million for the three months ended September 30, 2018, from $4.1 million for the three months ended September 30, 2017. This decrease is primarily the result of lower SYN-004 (ribaxamase) and SYN-010 program costs for the three months ended September 30, 2018 since no clinical trials were ongoing during the quarter. The research and development costs incurred during the quarter were primarily related to planning for future Phase 3 (SYN-004) and Phase 2b/3(SYN-010) clinical programs as we sought to secure the financial resources necessary for the advancement of these clinical trials. The charge related to stock-based compensation expense was $289,000 for the three months ended September 30, 2018, compared to $317,000 for the three months ended September 30, 2017.

Other income was $631,000 for the three months ended September 30, 2018, compared to other expense of $5.1 million for the three months ended September 30, 2017. Other income for the three months ended September 30, 2018 is primarily comprised of non-cash income of $626,000 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 from the prior quarter.

Cash and cash equivalents as of September 30, 2018 totaled $9.5 million, a decrease of $7.6 million from December 31, 2017, which does not reflect the proceeds from the sale of our securities during October 2018. During October 2018, we raised gross proceeds of approximately $18.6 million from the closing of a public offering of common stock and Series B Preferred Stock and received net proceeds of approximately $5.8 million from sales of our Common Stock in “at-the-market” equity offerings.
