JERSEY CITY, N.J., June 09, 2021 (GLOBE NEWSWIRE) — SCYNEXIS, Inc. (NASDAQ: SCYX), a biotechnology company pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant fungal infections, today announced that the U.S. Food and Drug Administration (FDA) granted BREXAFEMME (ibrexafungerp tablets), five years of exclusivity extension under the Generating Antibiotic Incentives Now (GAIN) Act. This exclusivity will be added to any other applicable exclusivity periods, such as the five years of new chemical entity (NCE) exclusivity, for a combined ten-year period of regulatory exclusivity. BREXAFEMME is also protected by multiple patents, including a composition-of-matter patent covering the ibrexafungerp molecule. With patent term extension, this patent is expected to expire in 2035, providing 14 years of protection from generic competitors in the U.S.

“With our first FDA approval behind us, we are very pleased to receive confirmation of BREXAFEMME’s five years of GAIN Act exclusivity for the treatment of vulvovaginal candidiasis,” said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. “We believe BREXAFEMME is an important treatment option to help patients with often resistant fungal infections and we look forward to educating the healthcare community about the availability of this exciting new product. We will also continue to work hard to fully leverage this regulatory exclusivity and our long patent protection to advance our pipeline of ibrexafungerp indications. Our vision is to create a long-lasting antifungal franchise in both hospital and community settings. We will provide a more comprehensive update on our VVC commercial plans on June 29^th.”

As a novel antifungal designed to treat serious and life-threatening infections, ibrexafungerp benefitted from Qualified Infectious Disease Product (QIDP) designation, which made it eligible to receive the GAIN Act exclusivity. This act was passed in 2012 for the purpose of stimulating the development and approval of new antibiotic and antifungal drugs.

About Vulvovaginal Candidiasis
VVC, commonly known as a vaginal yeast infection due to Candida, is the second most common cause of vaginitis. Although these infections are frequently caused by Candida albicans, infections caused by fluconazole-resistant and non-albicans Candida strains, such as Candida glabrata, have been reported to be on the rise. VVC can be associated with substantial morbidity, including significant genital discomfort (pain, itching, burning), reduced sexual pleasure and activity, psychological distress (stress, depression, anxiety), embarrassment, reduced physical activity, and loss of productivity. Typical VVC symptoms include pruritus, vaginal soreness, irritation, excoriation of vaginal mucosa and abnormal vaginal discharge. An estimated 70-75% of women worldwide will have at least one episode of VVC in their lifetime, and 40-50% of them will experience multiple episodes.

Currently approved treatments for VVC include BREXAFEMME (ibrexafungerp tablets), several topical antifungals, and oral fluconazole, which is the only other orally administered antifungal approved for the treatment of VVC in the U.S. and which has typically accounted for over 90% of the prescriptions written for this condition every year.

About BREXAFEMME^® (ibrexafungerp tablets), for oral use
BREXAFEMME is the trade name for ibrexafungerp, a novel oral antifungal approved for the treatment of vulvovaginal candidiasis (VVC), also known as vaginal yeast infection. Its mechanism of action, glucan synthase inhibition, is fungicidal against Candida species, meaning it kills fungal cells. The New Drug Application (NDA) for BREXAFEMME was approved by the U.S. Food and Drug Administration (FDA) on June 1, 2021. The NDA was supported by positive results from two Phase 3, randomized, double-blind, placebo-controlled, multi-center studies (VANISH-303 and VANISH-306), in which oral ibrexafungerp demonstrated efficacy and a favorable tolerability profile in women with VVC. BREXAFEMME represents the first approved drug in a new antifungal class in over 20 years and is the first and only treatment for vaginal yeast infections which is both oral and non-azole.
