JERSEY CITY, N.J. - SCYNEXIS, Inc. (NASDAQ: SCYX), a biotechnology company pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections, announced presentations of a pooled data analysis from its successful VANISH clinical development program during two October medical meetings: the Nurse Practitioners in Women's Health (NPWH) 24th Annual Premier Women's Healthcare Conference and the 4th Congress of the International Society for Infectious Diseases in Obstetrics and Gynecology (ISIDOG).

'Prior to the approval this year of BREXAFEMME (ibrexafungerp tablets), the treatment landscape for vaginal yeast infections had not seen a new class of antifungals since the 1990s despite the fact that three out of four women suffer from this condition at least once over the course of their lives,' said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. 'We are deeply committed to innovation in the field of women's health and are extremely pleased to be able to share this additional pooled data analysis from our groundbreaking VANISH clinical research.'

About Vulvovaginal Candidiasis (VVC)

Vulvovaginal Candidiasis (VVC), commonly known as a vaginal yeast infection due to Candida, is the second most common cause of vaginitis. Although 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.1 VVC can be associated with significant discomfort (pain, itching, burning), reduced sexual pleasure and activity, psychological distress (stress, depression, anxiety), embarrassment, reduced physical activity, and loss of productivity. An estimated 70-75% of women worldwide will have at least one episode of VVC in their lifetime, and 40-50% of those will experience multiple episodes.2

About BREXAFEMME (ibrexafungerp tablets)

BREXAFEMME is 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.3 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.4

INDICATION

BREXAFEMME is a triterpenoid antifungal indicated for the treatment of adult and postmenarchal pediatric females with vulvovaginal candidiasis (VVC).

DOSAGE AND ADMINISTRATION

The recommended dosage of BREXAFEMME is 300 mg (two tablets of 150 mg) twice a day for one day, for a total treatment dosage of 600 mg. BREXAFEMME may be taken with or without food.

BREXAFEMME administration during pregnancy may cause fetal harm based on animal studies. Prior to initiating treatment, verify pregnancy status in females of reproductive potential and advise them to use effective contraception during treatment

When administering BREXAFEMME with strong CYP3A inhibitors, the dose of BREXAFEMME should be reduced to 150 mg twice a day for one day. Administration of BREXAFEMME with strong CYP3A inducers should be avoided
