A Open-Label, Within-Subject Dose-Escalation Study to Evaluate the Clinical Safety and Pharmacokinetic Profile of a Topical Sildenafil Cream (5% w/w), in Healthy Postmenopausal Women

This is a Phase 1, single center, open-label, within-subject dose-escalation study evaluating the safety and pharmacokinetics of SST-6006 in healthy postmenopausal women. Three dose levels of SST-6006 and a placebo regimen will be evaluated: 1 g (0 mg of sildenafil), 1 g (50 mg of sildenafil), 2 g (100 mg of sildenafil), and 4 g (200 mg of sildenafil). Doses will be administered sequentially and will be separated by a 14-16 day washout period. All 3 dose levels and the placebo will be applied both externally and internally.
