Synthetic Biologics Reports 2017 Year End Operational Highlights and Financial Results

Company Provides Update on Late-stage Microbiome-focused Product Candidates

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 a clinical programs update and reported financial results for the year ended December 31, 2017.

“In 2017, Synthetic Biologics achieved several important milestones in the advancement of our late-stage pipeline of best-in-class microbiome product candidates targeting the prevention and treatment of life-threatening bacterial infections and gut microbiome disorders.  We are excited by the potential of our clinical programs to improve patient outcomes and quality of life and are working closely with the FDA to develop a path forward for SYN-004 (ribaxamase), targeting an end of Phase 2 meeting with the FDA during the second half of 2018,” said Steven Shallcross, Interim Chief Executive Officer and Chief Financial Officer. “We believe SYN-004, when co-administered with certain intravenous beta-lactam antibiotics may help prevent the onset of primary Clostridium difficileinfection (CDI), overgrowth of pathogenic organisms and the emergence of antimicrobial resistance (AMR), thereby making current antibiotic therapy more effective, and preventing life-threatening infections which may result from antibiotic-mediated dysbiosis,” he added.

“In 2018, our priorities are to establish the optimal clinical protocol for SYN-004’s Phase 3 study design, in collaboration with the FDA, and to continue to aggressively evaluate potential strategic relationships to speed the advancement and maximize the potential for success for our late-stage product candidates, including both SYN-004 and SYN-010 for the treatment of IBS-C,” concluded Shallcross.

Clinical Development and Operational Update

  • Presented additional supportive results regarding several exploratory endpoints from a Phase 2bproof-of-concept clinical trial designed to evaluate SYN-004’s (ribaxamase) ability to protect the gut microbiome from opportunistic bacterial infections and prevent the emergence of antimicrobial resistance in the gut microbiome in 4Q 2017
  • Plan to continue collaborative discussions with the FDA to solidify details and components of the drug development plan and regulatory pathway towards marketing approval for SYN-004 (ribaxamase) in the 1H 2018
    • Anticipate End of Phase 2 meeting with FDA in the 2H 2018
    • Plan to initiate Phase 3 clinical trial(s) in 2019
  • Continue efforts to solidify clinical infrastructure to support successful advancement of SYN-010, designed to treat an underlying cause of the symptoms associated with irritable bowel syndrome with constipation (IBS-C)

Year Ended December 31, 2017 Financial Results

General and administrative expenses decreased to $7.5 million for the year ended December 31, 2017, compared to $10.1 million for the year ended December 31, 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, and higher investor relations, consulting and legal costs in 2016 related to our 2016 equity financing. The charge relating to stock-based compensation expense was $2.0 million for the year ended December 31, 2017, compared to $2.4 million for the year ended December 31, 2016.

Research and development expenses decreased to $18.8 million for the year ended December 31, 2017, from $29.1 million for the year ended December 31, 2016. This decrease is primarily the result of lower SYN-004 (ribaxamase) and SYN-010 program costs for 2017 as we plan for future Phase 3 (SYN-004) and Phase 2b/3 (SYN-010) clinical programs and seek to secure the financial resources necessary for the completion of these clinical trials. In addition, there were reductions in our other research and development activities, offset by an increase in indirect costs for medical affairs and manufacturing scale up activities for SYN-004 (ribaxamase). Research and development expenses also include a charge relating to non-cash stock-based compensation expense of $1.4 million for the year ended December 31, 2017, compared to $1.6 million for the year ended December 31, 2016.

Other income was $10.8 million for the year ended December 31, 2017, compared to other income of $11.4 million for the year ended December 31, 2016. Other income for the year ended December 31, 2017 is primarily due to non-cash income of $10.7 million from the change in fair value of warrants. The decrease in the fair value of warrants was due to the decrease in our stock price from December 31, 2016.

Cash and cash equivalents on December 31, 2017 were $17.1 million, a decrease of $2.0 million from December 31, 2016.
