Official Title: An Exploratory Study of the Safety and Efficacy of BOTOX® for the Treatment of Premature Ejaculation

Brief Summary: This is a safety and efficacy study of BOTOX® (onabotulinumtoxinA) for the treatment of premature ejaculation in male patients.

Detailed Summary:

This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-escalation study to assess a range of doses of BOTOX for the treatment of male patients with PE. Patients will attend a minimum of 6 or 7 clinic visits and also have

1 or 2 telephone visits. Partners will need to attend a clinic visit during the screening period to provide informed consent and to receive training on measurement and recording of the IELT.

Patients will be enrolled in cohorts. Within the first 5 cohorts, 8 patients are to receive BOTOX and 2 patients to receive placebo. For cohort 6, 12 patients will receive BOTOX and 12 patients will receive placebo. Patients will receive a single treatment of study medication delivered bilaterally to the bulbospongiosus muscle. The initial BOTOX total dose in this dose escalation study will be 5 U and the maximum BOTOX total dose will be 100 U. Upon request and if eligible, patients in cohort 6, will have the option to receive a second injection of BOTOX (open label).
