Company: Scynexis (USA - NJ)
Product: SCY-078 ((1,3)-ß-D-glucan synthesis inhibitor)
Action
mechanism:
- enzyme inhibitor/glucan synthase inhibitor. SCY-078 is an oral and IV glucan synthase inhibitor in Phase 2 clinical development for the treatment for fungal infections caused by Candida and Aspergillus species. SCY-078 is a semi-synthetic triterpene derivative of the natural product enfumafungin—a structurally distinct class of glucan synthase inhibitor. 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 FDAgranted Fast Track, Qualified Infectious Disease Product (QIDP) and orphan drug designations (ODD) for the oral and IV formulations of SCY-078 for the indications of invasive Candida infections (including candidemia) and invasive Aspergillus infections.

Trial
details:
- Multicenter, randomized, active controlled, evaluator-blinded study of oral SCY-078 compared to oral fluconazole in adult female patients with acute vulvovaginal candidiasis (VVC). A total of 96 patients with an acute moderate to severe, symptomatic episode of VVC were randomized in a 1:1:1 ratio to receive either three daily doses or five daily doses of oral SCY-078 750mg QD with a 1,250mg loading dose or oral fluconazole, at the labeled approved dose regimen of 150mg single dose. This was a pilot investigation and not powered to demonstrate a statistical significant difference in the parameters tested (p values for the comparisons mentioned were >0.05 unless otherwise indicated). Efficacy was evaluated based on the proportion of patients achieving clinical cure, mycological eradication and therapeutic cure (combination of both clinical cure and mycological eradication) at day 24 (+/-3) after initiation of treatment. The 3-day and the 5-day SCY-078 regimens performed similarly, allowing a pooled analysis. Intent-to-treat (ITT) population is defined as all subjects randomized (n=96 subjects). Per-Protocol (PP) population is defined as subjects with culture confirmed Candida infection at baseline (n=70 subjects). Subjects in the PP population were followed for four months. Recurrence was defined as a symptomatic VVC episode requiring additional antifungal therapy, per investigators' decision. (NCT02679456)

news:
- • On October 5, 2016, Scynexis announced the complete results of a recently completed Phase 2 study. In this study, treatment with oral SCY-078 in patients with vulvovaginal candidiasis (VVC), resulted in significantly better clinical cure rates and fewer recurrences of VVC at the four-month follow-up when compared to the standard of care (oral fluconazole). The study evaluated the effect of two dose regimens of SCY-078 in patients with moderate to severe VVC as a proof-of-concept study to support the development of SCY-078 in invasive candidiasis and other Candida infections. Clinical cure rate, defined as a resolution of signs and symptoms of infection without further antifungal treatment, is now the recommended primary endpoint per the latest FDA guidelines for VVC. As previously reported, clinical cure rate was higher for patients receiving oral SCY-078 compared to oral fluconazole at the test of cure visit (Day 24). Additionally, follow-up data now available showed a high clinical cure rate at the four-month visit (end of observation period) of 88% in patients who received SCY-078 compared to 65% in patients who received fluconazole (p=0.04). Moreover, during the four-month observation period, patients who received SCY-078 had a lower recurrence rate (4%) versus fluconazole (15%).
As previously reported, SCY-078 was overall safe and tolerated. There were no discontinuations due to adverse events (AEs) and no related serious AEs. Consistent with previous findings, the most common AEs were mild to moderate gastrointestinal (GI) events such as diarrhea nausea, vomiting, abdominal pain or discomfort. In patients with invasive candidiasis, the number of GI events were comparable in both the SCY-078 and fluconazole treatment arms.
