ProF-001_Phase IIa

Summary

This is a multi-center, randomized, prospective, active-controlled, double-blind, dose-escalation study comparing dose response of clinical efficacy, safety, local tolerability of three different doses of ProF-001/Candiplus® (Candiplus® 0.2%, Candiplus® with 0.3%, Candiplus® with 0.4%) to 1% clotrimazole vaginal cream. Patients with acute episode of vulvovaginal candidiasis (VVC) will be randomized to receive a daily dose of either 5 ml (intravaginal) of Candiplus® at three different doses for the first 3 days and 2.5 ml for the remaining 3 days or 5 ml (intravaginal) application of 1% clotrimazole cream over the first 3 days and 2.5 ml for the remaining 3 days according to the following scheme (with each application 2 cm of cream will be applied to the vulvar region): Cohort 1: Candiplus® 0.2% versus clotrimazole mono Cohort 2: Candiplus® 0.3% versus clotrimazole mono Cohort 3: Candiplus® 0.4% versus clotrimazole mono Randomization into the cohorts will occur consecutively from the lowest dose to the highest dose, i.e. patients will be randomized first in cohort 1 and finally in cohort 3. The proposed study is - after a pilot study to assess critical pharmacokinetic data - the second study within a clinical trial program with the objective to develop a new combination therapy for the treatment of vulvovaginal candidiasis. The new combination consists of two registered drug substances.
