• PDUFA date set for September 17, 2017

 Newark, NJ, March 23, 2017 – Symbiomix today announced that the US Food and Drug Administration (FDA) has accepted for filing the Company’s New Drug Application (NDA) for its lead investigational product candidate Solosec™ (secnidazole oral granules), an innovative antibiotic designed to treat bacterial vaginosis (BV). In accordance with the FDA’s priority 6-month review designation, the agency has established a user-fee goal date under the Prescription Drug User Fee Act (PDUFA) of September 17, 2017. Symbiomix submitted the NDA filing in January 2017.

Solosec™ is a potent, next-generation, investigational 5-nitroimidazole antibiotic with enhanced pharmacokinetic properties, which will be the first and only single-dose oral therapy approved for BV if approved by the FDA. The FDA previously designated Solosec™ as a Qualified Infectious Disease Product (QIDP) for the treatment of BV and granted it Fast Track designation, which made Solosec™ eligible for priority review and at least 10 years of market exclusivity.

“The FDA’s acceptance of the NDA with priority review for Solosec™ is a critical milestone for Symbiomix,” said David L. Stern, Symbiomix CEO. “As a single-dose oral treatment, Solosec™ could improve adherence, potentially leading to better health outcomes for the millions of women suffering with BV. Solosec™ represents an important potential advancement in the treatment of women’s health infections.”

The Solosec™ NDA was supported by a comprehensive set of non-clinical and clinical studies conducted and reported by Symbiomix, including the two pivotal trials in BV (SYM-1219-201 and SYM-1219-301), results from which were presented at the Infectious Diseases Society for Obstetrics and Gynecology (IDSOG) Annual Meetings in 2015 and 2016, respectively.

About Solosec™

Solosec™ is a potent, next-generation, investigational 5-nitroimidazole antibiotic with enhanced pharmacokinetic properties. In clinical trials Solosec™ demonstrated efficacy for the treatment of BV with only a single, oral, two-gram dose, with excellent safety, tolerability and adherence.

 About Bacterial Vaginosis (BV)

BV is the most prevalent gynecological infection in the U.S. among women ages 15 to 44 [1,2]. Today more than four million women are treated in the US for BV annually [3]. More than 50 percent of women treated for BV have a recurrence within 12 months [4]. The U.S. Centers for Disease Control and Prevention (CDC) has stated that BV can cause serious health risks, including:

  • Increasing the risk of HIV transmission;
  • Increasing the risk of contracting other sexually transmitted diseases, such as chlamydia and gonorrhea, which, if untreated, may lead to pelvic inflammatory disease and infertility; and
  • In pregnant women, increasing the risk of delivering a baby too early [2].

BV disproportionately affects disadvantaged populations, including women of color, and may contribute to persistent disparities in women’s health outcomes [5,6].

BV has a significant impact on the work productivity and quality-of-life of affected women, with 60% of recurrent sufferers reporting a negative impact on work attendance, job performance and productivity, and 95% reporting a severe restriction in intimate partner relations [7,8].

The current recommended regimen of a first-generation nitroimidazole requires twice-a-day dosing for seven days for a total administration of seven grams of drug. Adherence with the current leading therapy for the treatment of BV has been shown to be only approximately 50 percent [9]. Poor adherence to anti-infective therapy is a problem that increases with the length and complexity of the drug regimen, and can lead to treatment failures, recurrent disease and the more rapid development of resistant microorganisms [10]. These, in turn, may lead to higher health care costs, including increased out-of-pocket expenses, increased office visits and tests, additional treatment costs, and lost productivity [11].
