Synthetic Biologics Reports Second Quarter 2013 Financial Results and Operational Update

— Progress Cited On Three Infectious Disease Programs, Including Two Programs in Collaboration with Intrexon Corporation; C. difficile Prophylactic is Lead Anti-Infective Candidate —

ROCKVILLE, Md., Aug. 14, 2013 /PRNewswire/ — Synthetic Biologics, Inc. (NYSE MKT: SYN), a developer of biologics focused on the prevention and treatment of serious infectious diseases, today reported financial results for the three and six months ended June 30, 2013 and provided an operational update.

The Company’s development portfolio includes three anti-infective product candidates, two of which are being developed in collaboration with Intrexon Corporation (NYSE: XON), and an oral multiple sclerosis (MS) product candidate in Phase II development. The relapsing-remitting MS clinical trial is expected to be completed in January 2014, with key data to be released shortly thereafter.

“Our lead anti-infective candidate SYN-004 for the prevention of C. difficile (C. diff) infections, is a second generation compound designed to address a broader population than its predecessor, which successfully completed a proof-of-concept Phase II study in Europe,” said Jeffrey Riley, Synthetic Biologics’ CEO. “Manufacturing of SYN-004 is underway, and with completion of that we will be able to commence toxicology bridging studies, followed by the start of clinical trials in 2014.”

“In addition, we are making excellent progress in our collaboration with Intrexon for antibody programs, which currently covers treatment candidates for Pertussis and Acinetobacter infections. We expect to initiate IND-enabling studies of our Pertussis candidate before year end,” said Mr. Riley.

Mr. Riley continued, “In developing and interlinking cutting edge cellular technologies for a broad range of applications as Intrexon does, an antibody discovery platform has been created that is powered to yield novel molecular entities intended to treat diseases for which current therapies are inadequate. Our collaboration with Intrexon is a prime example of how two innovative companies can work together to pursue significant medical advances.”

“The Company’s C. diff and Acinetobacter candidates may qualify for expedited review programs at the FDA for the treatment of serious conditions with unmet medical needs, such as are addressed by the GAIN Act.  The expedited programs established by the FDA not only point to the urgency for new medications for devastating diseases, but also potentially shorten the time to market,” concluded Mr. Riley.

The Company’s core competencies in anti-infectives have been strengthened with the recent appointment of industry veteran Lewis Barrett to the post of Senior Vice President, Commercial Strategy. Mr. Barrett was formerly Assistant Vice President, Established Products at Pfizer and Vice President Global Business Manager, Infectious Diseases at Wyeth Pharmaceuticals.

Operational Highlights

SYN-004 Product Candidate for Point-of-Care Prevention for C. diff Infections

  • This second generation candidate is believed to be the only product under development to prevent, rather than treat, C. diff infections. Healthcare-acquired infections with C. diff are potentially lethal and affect 1.1 million patients,[1] adding roughly $8.2 billion to U.S. hospital costs[2] annually. SYN-004 is designed to be administered along with target IV antibiotics to prevent C. diff. In July 2013, the SYN-004 manufacturing process was initiated with the evaluation of beta-lactamase protein expression in Fujifilm Diosynth Biotechnologies UK Limited’s pAVEway platform. Synthetic Biologics expects to initiate a clinical program for this second generation candidate in 2014.

“We believe SYN-004 is a breakthrough candidate within a market where no approved prophylactic for C. diff currently exists,” Mr. Riley noted. “As strange as it may seem, the only treatments available to patients are more antibiotics or fecal transplantation.”

Monoclonal Antibody (mAb) Programs in Collaboration with Intrexon Corporation

  • Our mAb product candidate for treatment of Pertussis, which is intended to neutralize the pertussis toxin, will undergo initial preclinical testing in the third quarter and is expected to enter IND-enabling studies before year end. Pertussis, or whooping cough, is responsible for 300,000 deaths annually worldwide[3] (primarily infants) and afflicts 41,000 people in the U.S. each year[4].
  • Our mAb for Acinetobacter infections is currently in the discovery stage.  The urgency to develop a treatment against this deadly pathogen remains high. Mortality rates as high as 43 percent have been reported[5], and incidence of the disease is reportedly increasing, especially among wounded military in field medical settings and natural disaster victims in emergency trauma units.

Phase II Study of MS Candidate, Trimesta

  • Topline results from a 164-patient relapsing-remitting MS Phase II trial at 15 centers are due in the first half of 2014.
  • In June 2013, Rhonda R. Voskuhl, M.D., was the keynote speaker at our investor day focused on MS. Dr. Voskuhl holds the titles of Professor, Department of Neurology, the Jack H. Skirball Chair in MS Research, and Director of the MS Program at UCLA School of Medicine, and is the lead investigator of the Phase II Trimesta™ clinical trial for relapsing-remitting MS. During the event, Dr. Voskuhl led an in-depth discussion about the MS space and the role of oral estriol (Trimesta™) in the treatment of MS (the archived webcast of this event is available at
  • In April 2013, we announced that U.S. Patent No. 8,372,826 was issued to the Regents of the University of California which includes claims to the use of our drug candidate, Trimesta™ (oral estriol), in combination with glatiramer acetate injection (Copaxone®). Copaxone® is the number one selling MS drug with approximately $4.2 billion in annual sales, marketed exclusively by Teva Pharmaceutical Industries Ltd. Copaxone® is expected to face generic competition as certain patent terms begin to expire in 2014.[6]

Three and Six Months Ended June 30, 2013 Financial Results

General and administrative expenses were $1.3 million and $2.4 million for the three and six months ended June 30, 2013, respectively, compared to $1.2 million and $2.6 million for the same periods in 2012. The decrease of 10% for the six month period ended June 30, 2013 is primarily the result of decreased outside legal and consulting fees. Non-cash charges related to stock-based compensation were $299,000 and $652,000 for the three and six months ended June 30, 2013, respectively, compared to $287,000 and $786,000 for the same periods in 2012.

Research and development expenses were $1.2 million and $2.3 million for the three and six months ended June 30, 2013, respectively, compared to $547,000 and $933,000 for the same periods in 2012. These increases of 120% and 149%, respectively, are primarily the result of additional employee costs and increased program costs associated with our infectious disease programs. Non-cash charges related to stock-based compensation were $109,000 and $212,000 for the three and six months ended June 30, 2013, respectively, compared to $113,000 and $122,000 for the same periods in 2012.
