Official title: A randomized, double-blind, placebo-controlled, parallel-group, study evaluating the efficacy, safety, and duration of erection of flexible-dose vardenafil administered for 12 weeks compared to placebo in subjects with erectile dysfunction and dyslipidemia
Trial description: This is a study consisting of four periods (screening, run-in, treatment, follow-up). A four-week treatment-free, run-in period where the subject will make at least four attempts at intercourse on four separate days with at least 50% of the attempts must be unsuccessful.
