MGCD290 and Fluconazole Versus Fluconazole Alone for the Treatment of Moderate to Severe Vulvovaginal Candidiasis

Study Overview
=================
Brief Summary
-----------------
The primary objective of the study is to evaluate the rate of therapeutic cure of the combination treatment of MGCD290 and fluconazole as compared to that of fluconazole alone at Test of Cure Visit for patients with moderate to severe vulvovaginal candidiasis.

Detailed Description
-----------------
MGCD290 is a novel antifungal agent targeting the Hos2 enzyme in fungi. MGCD290 was shown to potentiate and broaden the spectrum of activity of azole antifungal agents in vitro, especially fluconazole. MGCD290 taken together with fluconazole was observed to be safe in healthy volunteer studies. The current study is evaluating both the efficacy and safety of the combination treatment in subjects with moderate to severe vulvovaginal candidiasis.
