In September, pivotal results from Evofem's Phase 2b AMPREVENCE trial were presented at the 2020 STD Prevention Virtual Conference in a poster titled "Efficacy and safety of a novel vaginal pH modulator for prevention of chlamydia and gonorrhea." The biennial conference was organized by the U.S. Centers for Disease Control and Prevention (CDC) and the National Coalition of STD Directors. 

About the AMPREVENCE Trial
AMPREVENCE was a double-blinded, placebo-controlled Phase 2b clinical trial that enrolled 860 women who had been treated for chlamydia or gonorrhea in the four months prior to enrolling in the study. Subjects were randomized to receive either EVO100 vaginal gel or placebo vaginal gel. During the four months the women participated in the study, they were asked to apply the product candidate or placebo prior to each act of vaginal sexual intercourse. The primary and secondary endpoints of the study were the reduction in the incidence of urogenital Chlamydia trachomatis and Neisseria gonorrhea, respectively. Fifty centers in the United States participated in this unprecedented trial.

About the AMPOWER Trial
AMPOWER was a single-arm, open-label Phase 3 study designed to evaluate the efficacy and safety of Phexxi™ (lactic acid, citric acid and potassium bitartrate) in preventing pregnancy.  The study enrolled 1,384 women aged 18-35 years across 112 centers in the United States. AMPOWER is the only large-scale, Phase 3 contraceptive clinical trial to evaluate the effects of a contraceptive product candidate on the impact of women's sex lives (exploratory endpoint).
