Synthetic Biologics Reports 2016 Year End Operational Highlights and Financial Results

-- Company Highlights Clinical Successes of Late-stage Microbiome-focused Programs, Plans for Phase 3 Development --

-- Conference Call Today, March 2, 2017, at 4:30 p.m. (EST) --

ROCKVILLE, Md., March 2, 2017 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE MKT: 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, 2016.

"2016 was a transformative and momentum-building year for Synthetic Biologics," said Jeffrey Riley, President and Chief Executive Officer. "In the past 12 months, we announced positive proof-of-concept clinical results for our lead microbiome-focused programs representing significant milestones for our company. Most recently, we announced positive topline results from ribaxamase's global Phase 2b proof-of-concept clinical trial which achieved its primary endpoint by demonstrating a statistically significant reduction in the incidence of primary C. difficile infection (CDI) compared to placebo, positioning ribaxamase as a vanguard amongst microbiome-based therapeutics pursuing clinical development for this indication in Phase 2 trials or later. Data from this study also demonstrated that ribaxamase significantly reduced the incidence of new colonization by vancomycin-resistant enterococci (VRE) compared to placebo, potentially expanding the utility of our compound as a first line of defense against the development of antimicrobial resistance (AMR) in the gut microbiome. We believe ribaxamase may represent a disruptive yet simple approach to antibiotic therapy that may directly lead to more effective and efficient use of antibiotics."

Mr. Riley continued, "In 2017, we will look to build upon the progress of the last year and are focused squarely on achieving the important value-building milestones that lie ahead. Toward that end, we expect to share additional results in the coming months from several exploratory endpoints from our Phase 2b study focused on ribaxamase's ability to prevent the emergence of antimicrobial resistance in the gut microbiome. We will also be focused on continuing the clinical advancement of SYN-010 for the treatment of IBS-C, with our goal of initiating the Phase 2b/3 pivotal clinical trial later this year."     

Microbiome-Focused Clinical Program Progress 

SYN-004 – Prevention of C. difficile infection (CDI), antibiotic-associated diarrhea (AAD) and emergence of antimicrobial resistance (AMR):

  • Awarded research contract from the Centers for Disease Control and Prevention (CDC) to support research from Phase 2b clinical trial to determine ribaxamase's ability to prevent the emergence of antibiotic-mediated antimicrobial resistance (AMR) in the gut microbiome (4Q 2016)
  • Reported positive topline data from global Phase 2b proof-of-concept randomized, double-blind, placebo controlled clinical trial of 412 patients (1Q 2017)
    • Achieved primary endpoint, demonstrating a statistically significant relative risk reduction of 71.4% (p=0.045) in CDI rates versus placebo
    • Demonstrated a significant reduction in new colonization by vancomycin-resistant enterococci (VRE) for patients receiving ribaxamase versus placebo (p-value=0.0002)
    • Demonstrated a positive trend (p-value=0.13) towards reducing the incidence of antibiotic- associated diarrhea (AAD) from all causes versus placebo
  • Expect to share results from several exploratory endpoints designed to evaluate ribaxamase's ability to protect the gut microbiome from opportunistic bacteria and prevent the emergence of antimicrobial resistance (AMR) in the gut microbiome (1H 2017)
  • Anticipate requesting end of Phase 2 meeting with FDA (2H 2017)
  • Expect to initiate Phase 3 clinical trial(s) (1H 2018)

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

  • Confirmed key elements of Pivotal Phase 2b/3 clinical trial pursuant to consultations with the FDA (1Q 2017)
    • A 12-week, multi-center, double-blind, placebo-controlled, adaptive design clinical trial
    • A study population of approximately 840 adult subjects diagnosed with IBS-C
    • Evaluation of efficacy and safety of two dose strengths of SYN-010 (21 mg and 42 mg) compared to placebo
    • Conducted in approximately 150 clinical sites in North America
    • Study subjects will be randomized in a 1:1:1 ratio, receiving either 21 mg of SYN-010, 42 mg of SYN-010, or placebo
    • Enrollment is open to all IBS-C patients; breath-methane will be measured at baseline to ensure a comparable ratio of high-to-low breath methane IBS-C patients in each treatment arm
    • An interim futility analysis may be conducted when approximately 50% of patients in each dosing arm have completed treatment
  • Plan to initiate first Phase 2b/3 adaptive pivotal clinical trial (2017)

Operational Update

  • Reinforced balance sheet with net proceeds of $23.3 million from November 2016 public offering to support the continued clinical development of SYN-010, including initiation of a planned Phase 2b/3 adaptive pivotal clinical trial

Year Ended December 31, 2016 Financial Results

General and administrative expenses were $10.1 million for the year ended December 31, 2016, compared to $8.1 million for the same period in 2015. This increase is primarily the result of bank and legal fees related to the November 2016 financing associated with the warrant liability, increased employee costs, costs associated with the transition of the administrative and financial office to our Maryland headquarters, and an increase in stock-based compensation. Non-cash charges related to stock-based compensation were $2.4 million for the year ended December 31, 2016, compared to $2.1 million for the same period in 2015.

Research and development expenses decreased to $29.1 million for the year ended December 31, 2016, from $32.9 million for the same period in 2015. This decrease is primarily the result of decreased program costs associated with clinical development programs and research activities within our pathogen-specific microbiome-focused pipeline, including our IBS-C and Pertussis programs offset by an increase in C. difficile program costs and an increase in manufacturing costs. In 2015, we entered into an ECC with Intrexon Corporation for the development of a treatment for patients with PKU. Pursuant to the ECC, we issued 937,500 shares of our common stock in August 2015 to Intrexon Corporation as payment for the technology access fee that resulted in a non-cash charge of $3.0 million. Research and development expenses for 2015 also include a $1.0 million non-cash expense for achieving the third milestone as set forth in the Asset Purchase Agreement with Prev ABR LLC, dated November 28, 2012. Prev ABR LLC exercised its option to receive the milestone payment in shares of our common stock that were issued in April 2015. Research and development expenses also include a charge relating to non-cash stock-based compensation expense of $1.6 million for the year ended December 31, 2016, compared to $1.1 million for the year ended December 31, 2015.

Other income was $11.4 million for the year ended December 31, 2016, compared to other expense of $3.8 million for the same period in 2015. Other income for the year ended December 31, 2016 is primarily due to non-cash income of $11.4 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 the year ended December 31, 2015.

Cash and cash equivalents on December 31, 2016 were $19.1 million, a decrease of $1.8 million from December 31, 2015.
