Presentations support SCY-078's potential as a novel treatment for
Candida infections including multidrug-resistant strains
Favorable safety profile of SCY-078 supported by clinical studies presented
Conference call to review ECCMID SCY-078 data to be held April 25 at 4:05 p.m. ET
JERSEY CITY, N.J., April 25, 2017 (GLOBE NEWSWIRE) -- SCYNEXIS, Inc. (NASDAQ:SCYX), a biotechnology company delivering innovative anti-infective therapies for difficult-to-treat and often life-threatening infections, today announced results showing evidence of activity of the company's lead product candidate SCY-078 against fungal infections in multiple settings and indications. These results were described in a total of eight oral and poster presentations at the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), held April 22 through 25, 2017 in Vienna, Austria.
The first oral presentation (#OS0846) described new data from a multicenter Phase 2 trial that examined oral SCY-078 compared with standard-of-care (oral fluconazole or intravenous micafungin) following initial intravenous (IV) echinocandin therapy for the treatment of invasive candidiasis. SCY-078 demonstrated safety among all treatment groups and achieved a global response rate similar to standard-of-care. Additionally, an estimated dose to achieve target exposure was identified. The findings support the use of oral SCY-078 in the treatment of invasive candidiasis following initial IV echinocandin therapy.
"We're seeing a rising incidence of patients becoming resistant to today's current therapies treating invasive candidiasis, which poses a global health threat," said Peter G. Pappas, M.D., lead investigator on the study and Professor at the University of Alabama at Birmingham. "The discovery and development of potentially novel therapies, like SCY-078, are vital to the management of these invasive and life-threatening infections."
The second oral presentation (#EP0698) described the antifungal activity of SCY-078 against the emerging drug-resistant fungal infection Candida auris. In this preclinical study, SCY-078 impacted the growth morphology and biofilm formulation of these invasive and life-threatening fungal species. Results showed potent activity of SCY-078 against all strains at concentrations indicative of a potential clinically-relevant effect.
"Candida auris is an emerging, multidrug-resistant fungal species now infecting patients globally, with a mortality rate of approximately 60%," said Mahmoud Ghannoum, Ph.D., Professor at the Center for Medical Mycology in the Department of Dermatology at Case Western Reserve School of Medicine. "Given that certain fungal strains that have been isolated from patients have proven to be resistant to all commercially available antifungal drugs, the need for effective new therapies has become a dire global health need."
The remaining presentations — all delivered via poster presentations — detailed the results of six separate studies, which assessed the safety, efficacy, and pharmokonetics of SCY-078 across both Aspergillus and Candida strains. All studies supported the significant antifungal activity and positive safety profile found to date. Conclusions from the poster presentations included:
• In vitro synergies of SCY-078 in combination with other antifungals against Aspergillus
• Safety and efficacy of SCY-078 in two Phase 1 drug-drug interaction studies
• Additional posters confirming SCY-078's broad spectrum of activity in clinical and pre-clinical settings
"The wide range of clinical and non-clinical results from the SCY-078 development program at ECCMID provide further evidence of its strong anti-fungal effect and the significant impact it could have in treating patients, both as a stand-alone treatment and in combination with currently marketed drugs," said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. "These results support our commitment to building not only next-generation therapeutics but a platform of much-needed, potent, safe, flexible and easy-to-administer anti-infective alternatives."
In addition to data presentations, SCYNEXIS provided an overview of its pipeline and recent advances at ECCMID. This overview, along with all presentations and posters, are available at www.SCYNEXIS.com.

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 Candida auris Infections
Candida auris, a fungal strain first reported in 2009, has been linked to invasive fungal infections in nine countries, including the U.S., and has caused at least two hospital outbreaks involving more than 30 patients each. The CDC estimates that infections with C. auris are associated with a mortality rate of approximately 60% and that some strains of this species of Candida have proven to be resistant to all three major classes of antifungal drugs, making treatment difficult. This type of broad resistance to approved antifungal agents has not been observed in other species of Candida. Types of infections caused by C. auris include bloodstream, wound and ear infections. The fungal strain has also been isolated from respiratory and urine specimens, although it is unclear if it causes infections in the lung or bladder. The CDC is actively tracking C. auris infections globally and has already issued an alert to all healthcare facilities classifying this new pathogen as a serious global health threat.
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.
