Detailed Description:

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.


Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Are male or female 18 to 65 years of age, inclusive
  • Are able and willing to follow study procedures and instructions
  • Are able to read, understand and sign an informed consent form
  • Are documented as HIV positive
  • Have pseudomembranous and/or erythematous oral candidiasis as confirmed by potassium hydroxide preparation of mucosal scraping
  • Have a CD4 cell count performed prior to randomization or within 6 weeks prior to the screening visit
  • Have a viral load performed prior to randomization or within 6 weeks prior to the screening visit.
  • Both men and women who are active heterosexually must be willing to practice a medically accepted method of birth control.

Exclusion Criteria:

  • Have received systemic antifungal therapy within 14 days of starting study
  • Have received prior topical therapy for oral candidiasis within 7 days of starting study
  • Have a concomitant fungal infection requiring systemic therapy
  • Are currently receiving immunosuppressive therapy (e.g. corticosteroids), or cancer chemotherapy

Subjects who use hormonal contraceptives must have started the method at least 30 days prior to the screening examination
  • Active substance abuse

    • Serum creatinine >2 times ULN
  • Have peri-oral lesion (perleche) only
  • Have oral manifestations of herpes simplex (active disease only), hairy leukoplakia and/or aphthous ulcers
