SAN DIEGO, Sept. 14, 2020 /PRNewswire/ -- Evofem Biosciences, Inc. (NASDAQ: EVFM) today announced pivotal results from the Phase 2b AMPREVENCE trial in a poster presentation from the 2020 STD Prevention Virtual Conference, which will take place online September 14 through 24.

AMPREVENCE evaluated the safety and efficacy of the Company's investigational product candidate EVO100 for the prevention of urogenital chlamydia and gonorrhea in women. The Phase 2b study met its primary and secondary endpoints, with women receiving EVO100 experiencing a relative risk reduction for chlamydia and gonorrhea infection of 50% and 78%, respectively, compared to women receiving placebo. EVO100 was generally safe and well tolerated by women participating in the study.

Positive, statistically significant data from the AMPREVENCE study along with a recent data review from the FDA has positioned Evofem to begin a Phase 3 clinical trial of EVO100 for prevention of chlamydia and gonorrhea in women in the fourth quarter of 2020.

"EVO100 has the potential to impact the health of millions of women by reducing infection rates of chlamydia and gonorrhea," said Kelly Culwell, M.D., Evofem Biosciences' Chief Medical Officer. "We recently had a productive Type C meeting with the FDA that confirmed a very clear path forward in our clinical development and we look forward to initiating our Phase 3 clinical trial before the end of the year."

According to the U.S. Centers for Disease Control and Prevention (CDC), rates of infection for Chlamydia trachomatis and Neisseria gonorrhea climbed in 2018 for the fifth consecutive year in the United States. Nearly 2.4 million domestic cases of these sexually transmitted infections (STIs) were diagnosed in 2018, with 1.8 million newly reported chlamydia cases and approximately 580,000 newly reported gonorrhea cases.1 The CDC also reported that gonorrhea is increasingly becoming antibiotic resistant, making it much harder, or sometimes impossible, to treat.2

"Chlamydia and gonorrhea are both urgent public health issues with significant consequences, and the emergence of drug-resistant gonorrhea demonstrates that treatment alone is not going to curb this growing epidemic," said poster author B. Todd Chappell, M.D., an AMPREVENCE investigator and obstetrician/gynecologist practicing at Adams Patterson Gynecology & Obstetrics in Memphis, Tennessee. "I am very encouraged by the results of the AMPREVENCE trial and the notion that, in the future, we may be able to provide women with an innovative option to help prevent the acquisition of STIs."

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.
