Synthetic Biologics Reports Second Quarter 2017 Operational Highlights and Financial Results

ROCKVILLE, Md., Aug. 3, 2017 /PRNewswire/ — 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, 2017.

“During the second quarter, we achieved additional and exciting progress for our lead microbiome-focused programs,” said Jeff Riley, President and Chief Executive Officer of Synthetic Biologics. “The important momentum generated during the quarter is perhaps best illustrated by the FDA’s granting of a Breakthrough Therapy Designation to ribaxamase, the first ever such designation of a drug candidate for the prevention of Clostridium difficile infection (CDI). We have submitted a request for a Type-B multidisciplinary meeting with the FDA to discuss potential options to expedite the development and review timelines for ribaxamase’s clinical advancement and path towards marketing approval. We look forward to working closely with the FDA on how to best move forward with this novel, complimentary and potentially paradigm-shifting approach which may directly lead to more effective and efficient antibiotic therapy.”

Mr. Riley continued, “We also continued to be keenly focused on ensuring we have in place the optimal timing and path forward for the clinical advancement of SYN-010, our promising candidate for the treatment of irritable bowel syndrome with constipation (IBS-C). In June, we were pleased to announce that the U.S. Patent and Trademark Office (USPTO) issued a Notice of Allowance for a patent which covers the use of the active agent of SYN-010 to treat constipation until at least 2034, significantly strengthening the opportunity to build long-term value for our shareholders.”

Microbiome-Focused Clinical Program Progress

SYN-004 – Prevention of C. difficile infection (CDI), overgrowth of pathogenic organisms and the emergence of antimicrobial resistance (AMR):

• Announced that the U.S. Food and Drug Administration (FDA) granted the first-ever Breakthrough Therapy Designation to SYN-004 (ribaxamase) for the prevention of Clostridium difficile infection
• Announced additional results from several exploratory endpoints from Phase 2b proof-of-concept clinical trial funded under a contract awarded to the Company from the Centers for Disease Control and Prevention (CDC), demonstrating that SYN-004 (ribaxamase) prevented significant change to the presence of certain AMR genes in the gut resistome of patients receiving SYN-004 (ribaxamase) compared to placebo (Q3 2017)
• Expect to share additional results from several exploratory endpoints from Phase 2b proof-of-concept clinical trial designed to evaluate SYN-004’s (ribaxamase) ability to protect the gut microbiome from opportunistic bacteria and prevent the emergence of antimicrobial resistance (AMR) in the gut microbiome (2H 2017)
• Submitted a request for a Type-B multidisciplinary meeting with the FDA to discuss the overarching, high-level drug development plan and pathway towards marketing approval for SYN-004 (ribaxamase) (2H 2017)
• Plan to initiate Phase 3 clinical trial(s) (1H 2018)

SYN-010 – Treatment of irritable bowel syndrome with constipation (IBS-C):

• Announced that the U.S. Patent and Trademark Office (USPTO) issued a Notice of Allowance for a patent which covers the use of the active agent of SYN-010 for the treatment of constipation until at least 2034
• Continue to solidify infrastructure to support successful clinical advancement of SYN-010

Synthetic Biologics also announced that five abstracts have been accepted for presentation at Infectious Disease Week 2017™ taking place at the San Diego Convention Center in San Diego, CA from October 4 – 8, 2017.

Second Quarter 2017 Financial Results

General and administrative expenses decreased by 23% to $1.6 million for the second quarter of 2017, from $2.1 million for the second quarter of 2016. This decrease is primarily the result of higher salary expense and related benefits costs incurred in 2016 in connection with the transition of the administrative and financial office to our Maryland headquarters, along with a reduction of travel and legal expenses in 2017. The charge related to stock-based compensation expense was $539,000 for the second quarter of 2017, compared to $507,000 for the second quarter of 2016.

Research and development expenses decreased by 33% to $4.8 million for the second quarter of 2017, from $7.2 million for the second quarter of 2016. This decrease is primarily the result of lower SYN-004 (ribaxamase) program costs. In addition, there were reductions in our other research and development activities, including our SYN-010 program, offset by an increase in indirect costs for medical affairs.  Research and development expenses also include a charge related to stock-based compensation expense of $331,000 for the second quarter of 2017, compared to $400,000 for the second quarter of 2016.

Other income was $2.2 million for the second quarter of 2017, compared to other income of $3.5 million for the second quarter of 2016. Other income for the second quarter of 2017 is due to non-cash income of $2.2 million 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 June 30, 2017 remained relatively unchanged at $13.4 million, a small decrease from the prior quarter.
