JERSEY CITY, N.J., April 12, 2017 (GLOBE NEWSWIRE) -- SCYNEXIS, Inc. (NASDAQ:SCYX), a biotechnology company delivering innovative anti-infective therapies for difficult-to-treat and life-threatening infections, today announced eight data presentations at the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), April 22 to 25, 2017, in Vienna, Austria.

All presentations will feature data related to the development of the company's lead product candidate, SCY-078, the first representative of a novel intravenous (IV) and oral triterpenoid antifungal family in Phase 2 clinical development for the treatment of several fungal infections, including serious and life-threatening invasive fungal infections.

"SCY-078 is proving to be broad spectrum, active against resistant strains, versatile as both IV and oral treatments with high tissue distribution, fungicidal activity and a favorable safety profile," said Marco Taglietti, M.D., president and CEO of SCYNEXIS. "Our significant presence at ECCMID emphasizes our strong ties to the scientific community and our commitment to delivering novel products to treat these life-threatening fungal infections, including new and multi-drug-resistant pathogens like C. auris  that are becoming a major global threat. The SCYNEXIS' scientific team, in collaboration with renowned academic centers, has generated valuable data that reinforce the unique attributes of SCY-078, a promising candidate offering the potential to positively impact the way severe fungal infections are treated."

Along with the oral data presentation detailed below, SCYNEXIS will provide an overview of its pipeline and recent advances in the ECCMID 2017 Pipeline Corner at 1:00 p.m. CEDT on Sunday, April 23.

All abstracts are available on the ECCMID website at www.eccmidlive.org.

About SCY-078
SCY-078 is an oral and IV antifungal agent in Phase 2 clinical development for the treatment of fungal infections caused by Candida and Aspergillus species. SCY-078 is a triterpenoid, semi-synthetic derivative of the natural product enfumafungin—a structurally distinct and novel class of glucan synthase inhibitor. SCY-078 combines the well-established activity of glucan synthase inhibitors (similar to echinocandins) with the flexibility of having IV and oral formulations (similar to azoles). By belonging to a chemical class distinct from other antifungals, SCY-078 has shown in vitro and in vivo activity against multi-drug resistant pathogens, including azole- and echinocandin-resistant strains. The U.S. Food and Drug Administration granted Fast Track, Qualified Infectious Disease Product and Orphan Drug Designations for the oral and IV formulations of SCY-078 for the indications of invasive candidiasis (including candidemia) and invasive aspergillosis.

About Invasive Candidiasis Infections
Invasive candidiasis is a serious, often life-threatening infection caused by Candida species that typically affects a highly vulnerable population such as immunocompromised patients or patients under intensive care in hospital settings.  We estimate that the U.S. annual incidence is approximately 100,000 cases with high mortality rates (i.e., 20-40%) despite currently available antifungal agents. Furthermore, the limited number of antifungal drug classes, consisting of azoles, echinocandins and polyenes, and their widespread use, has led to increased numbers of candida infections with drug-resistant strains. The Centers for Disease Control and Prevention (CDC) has listed fluconazole-resistant Candida as a serious public health threat requiring prompt and sustained action.

About Invasive Aspergillus Infections
Invasive aspergillosis is a serious fungal infection caused by Aspergillus species that usually affects people who have weakened immune systems, such as people who have had an organ transplant or a stem cell transplant. Invasive aspergillosis most commonly affects the lungs, but it can also spread to other parts of the body. There are approximately 50,000 cases of invasive aspergillosis reported in the U.S. annually, with a mortality rate as high as 50%. Current standard of treatment is eight to 12 weeks of azoles usually started as IV treatment for one to two weeks followed by oral step-down treatment for several weeks.

About Vulvovaginal Candidiasis Infections
Vulvovaginal Candidiasis (VVC), commonly known as a "yeast infection," is usually caused by Candida albicans and typical symptoms include pruritus, vaginal soreness, irritation and abnormal vaginal discharge. An estimated 75% of women will have at least one episode of VVC during their lifetime and 40%-45% will experience two or more episodes. As many as 8% of these patients suffer from recurrent VVC, defined as experiencing at least four episodes a year. Current treatments for VVC include topical antifungals and the use of prescription oral antifungals such fluconazole, which has a therapeutic cure rate of 55% as reported in the label. There are no products currently approved for the treatment recurrent VVC.
