Phase 2B Dose-Ranging Study of PAC113 Mouthrinse in HIV Seropositive Individuals With Oral Candidiasis
A Phase 2B Dose-Ranging Study of PAC113 Mouthrinse for Clinical and Microbial Evaluation in HIV Seropositive Individuals With Oral Candidiasis to Establish the Optimal Dose of PAC113
The purpose of this study is to determine the optimal dose of PAC113 mouthrinse for treatment of oral candidiasis in HIV seropositive patients.

This is a randomized, examiner-blinded, positive-controlled, parallel design clinical trial, which features 4 treatment arms. Forty-five (45)* HIV positive subjects per treatment arm will be recruited for 180 subjects total. The study includes 5 visits: a screening visit, a 14-day treatment phase with a baseline visit on Day 1, a Day 7 visit, a post-treatment visit 5 days after the last dose, and follow-up visit. During the screening visit subjects will be assessed for study eligibility. Eligible subjects will be randomized to 1 of the following treatment arms:

A. 0.15% PAC-113 mouthrinse (5 mL 4 times daily [q.i.d.]); B. 0.075% PAC-113 mouthrinse (5 mL q.i.d.); C. 0.0375% PAC-113 mouthrinse (5 mL q.i.d.); D. Nystatin oral suspension (100,000 units/mL; 5 mL q.i.d.) Subjects will be evaluated clinically for safety and severity of clinical signs and symptoms of oral candidiasis at baseline (Day 1), Day 7, Day 19 (5 days post-treatment) and Day 28 (follow-up visit). Subjects will also have a microbiological analysis performed at screening, and at Days 7, 19 and 28.
