SCYNEXIS Completes Last-Patient/Last-Visit Ahead of Schedule in the First Phase 3 Study (VANISH 303) of Oral Ibrexafungerp for the Treatment of Vulvovaginal Candidiasis (VVC)

JERSEY CITY, N.J., Sept. 18, 2019 /PRNewswire/ -- SCYNEXIS, Inc. (NASDAQ: SCYX), a biotechnology company delivering innovative therapies for difficult-to-treat and often life-threatening infections, today announced completion of the last-patient/last-visit in its Phase 3 VANISH 303 study, and that it expects to release top-line data earlier than previously reported. Ibrexafungerp (formerly SCY-078) is the first representative of a novel family of antifungal compounds referred to as triterpenoids. SCYNEXIS is developing ibrexafungerp for the treatment of both serious outpatient fungal infections as well as hospital-based, life-threatening fungal infections.  

"I am proud to report that our VVC clinical studies are progressing ahead of schedule, showing the execution strength of our team. The last patient has completed her last visit in our first Phase 3 study, VANISH 303, and we now expect top-line data by the end of this year," said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. "Additionally, enrollment is also advancing ahead of expectations in our second Phase 3 study, VANISH 306, with data now anticipated in early second quarter of 2020." 

Dr. Taglietti continued, "The rapid enrollment observed in our VVC studies reaffirms our belief that a large number of patients and their treating physicians are not satisfied with existing therapies and are looking for alternatives. It provides validation of our VVC commercial expectations for ibrexafungerp, as a non-azole, fungicidal, oral agent. We remain on-track for a New Drug Application (NDA) submission in the second half of 2020."

Ibrexafungerp Update:

Significant progress made in the Phase 3 VANISH program evaluating the safety and efficacy of oral ibrexafungerp (300mg BID for one day) for the treatment of VVC

  • The VANISH program is comprised of two Phase 3, randomized, double-blind, placebo-controlled, multi-center studies:
    • The VANISH 303 study was conducted in U.S. centers and enrolled 376 patients. The last patient has now completed her final visit, ahead of schedule. Top-line data from the study is now expected by year-end 2019. More information about this study can be found at: https://clinicaltrials.gov/ct2/show/NCT03734991.
    • The VANISH 306 study is expected to enroll approximately 360 patients from sites in the U.S. and Europe; the enrollment rate is also exceeding expectations, and the Company now anticipates top-line data in early second quarter of 2020. More information about this study can be found at: https://clinicaltrials.gov/ct2/show/NCT03987620.
  • All NDA preparatory activities remain on track to support a planned NDA submission in the second half of 2020.

About Vulvovaginal Candidiasis (VVC)

VVC, commonly known as a "vaginal yeast infection," is the second most common cause of vaginitis. Although these infections are frequently caused by Candida albicans, fluconazole-resistant Candida strains, such as Candida glabrata, have been reported to become increasingly more common. VVC can be associated with substantial morbidity, including significant genital discomfort, reduced sexual pleasure, psychological distress 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 two or more episodes. Approximately 6-8% of women with VVC suffer from recurrent disease, defined as experiencing at least three episodes within a 12-month period.

Current treatments for acute VVC include several topical azole antifungals (clotrimazole, miconazole, and others) and fluconazole, the only orally-administered antifungal currently approved for acute VVC in the U.S. Fluconazole reported a 55% therapeutic cure rate in its label, which now also includes warnings of potential for fetal harm, illustrating the need for new oral alternatives. The needs of women with moderate-to-severe VVC, recurrent VVC, VVC caused by fluconazole-resistant Candida spp. or VVC during child-bearing age are not fully addressed by oral fluconazole or topical products. In addition, there are no oral alternatives for VVC patients who do not respond to or tolerate fluconazole, and there are no FDA-approved products for the prevention of recurrent VVC.

About Ibrexafungerp

Ibrexafungerp [pronounced eye-BREX-ah-FUN-jerp] is an investigational antifungal agent and the first representative of a novel class of structurally-distinct glucan synthase inhibitors, triterpenoids. This agent combines the well-established activity of glucan synthase inhibitors with the potential flexibility of having oral and intravenous (IV) formulations. Ibrexafungerp is currently in development for the treatment of fungal infections caused primarily by Candida (including C. auris) and Aspergillus species. It has demonstrated broad spectrum antifungal activity, in vitro and in vivo, against multidrug-resistant pathogens, including azole- and echinocandin-resistant strains. The FDA has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations for the formulations of ibrexafungerp for the indications of invasive candidiasis (IC) (including candidemia), invasive aspergillosis (IA) and VVC (including prevention of recurrent VVC) and has granted Orphan Drug Designation for the IC and IA indications. Ibrexafungerp is formerly known as SCY-078.
