Birth Control


Northern California Research is currently enrolling participants for a birth control study. The purpose of this study is to assess the effectiveness of a new form of birth control in preventing pregnancy. The study medication is a new, non-hormonal, birth control designed to maintain the pH of the vagina and to form a layer of gel over the vagina and cervix, preventing sperm from reaching an egg. This medication will be used as needed when engaging in vaginal sexual intercourse.

Our participants will be sexually active women, ages 18-35, who are using no other form of birth control (including condoms). This is not a double-blind study and every participant will be receiving study medication, Amphora. If you are on a birth control method you will be asked to discontinue the use of it in order to participate in this study. The study is 10 months long and includes 5 office visits. All trial-related visits, tests, and medications will be provided to you at no cost. In addition, reimbursement for trial-related time and travel may be provided.
