Healthy Clinical Trial
Official title:
Clinical Evaluation of Daily Application of Nestorone® (NES) and Testosterone (T) Combination Gel for Male Contraception
The long term objective is to develop a gel to be used as a male contraceptive.
This is a prospective, phase IIb, open label, single arm, multicenter study. The study protocol consists of a screening phase lasting 4 to 8 weeks, a suppression phase estimated up to 20 weeks, a 52-week maintenance/efficacy phase, and a 24-week (estimated) recovery phase. The study will involve approximately 420 couples recruited throughout the CCTN that meet eligibility criteria. Approximately fifteen sites propose to enroll up to 420 couples (about 30 to 60 couples per site) with a goal of obtaining 200 couples completing the contraceptive efficacy phase of the study. The study has four phases (screening phase, suppression phase, efficacy phase and recovery phase) with monthly visits to provide the male participants with the NES/T gel, to encourage adherence, to monitor for possible side effects, and to quantify semen parameters. The female partner will be contacted monthly and come in for a visit every three months. Male subjects will be treated and followed as outpatients, along with their participating female partner. ;
