SAN DIEGO, Oct. 20, 2020 /PRNewswire/ -- Evofem Biosciences, Inc., (NASDAQ: EVFM) today announced enrollment of the first patient in its pivotal Phase 3 clinical trial evaluating the safety and efficacy of EVO100 for the prevention of urogenital chlamydia and gonorrhea in women.

"We are thrilled to initiate the EVOGUARD trial to further evaluate EVO100 for prevention of chlamydia and gonorrhea infection in women, for which there are currently no prescription products available," said Kelly Culwell, MD, Chief Medical Officer for Evofem Biosciences. "Evofem continues to establish itself as a company that can develop and deliver unique products and product candidates to address the true unmet needs of women."

Rates of infection for Chlamydia trachomatis and Neisseria gonorrhea climbed in 2018 for the fifth consecutive year in the United States.¹ Globally, an estimated 95 million women are likely to contract chlamydia or gonorrhea by 2025.²

Gonorrhea is increasingly becoming antibiotic resistant, making it much harder, or sometimes impossible, to treat.³

"The dramatic rise and increasing prevalence of chlamydia and gonorrhea, along with the emergence of multi-drug resistant gonorrhea, make the development of a preventative measure such as EVO100 even more critical," Dr. Culwell added.

EVOGUARD is a double-blind, placebo-controlled Phase 3 clinical trial designed to evaluate the safety and efficacy of EVO100 for the prevention of urogenital Chlamydia trachomatis and Neisseria gonorrhea infection in women.

The study will enroll 1,730 women who have had a urogenital chlamydia or gonorrhea infection at any time over the 16 weeks preceding the Enrollment Visit along with one or more risk factors for infection. Participating women will be randomized to receive either EVO100 vaginal gel or placebo, and will remain in the study until completion of 16 weeks of study medication or observation or testing positive for chlamydia or gonorrhea infection.

In September 2020, pivotal results from Evofem's double-blinded, placebo-controlled 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."

AMPREVENCE enrolled 860 women who had been treated for chlamydia or gonorrhea in the four months prior to enrolling in the study. Fifty centers in the United States participated in this unprecedented trial.

EVO100 has been granted Fast Track Designation for the prevention of chlamydia in women by the FDA, and is an FDA-designated Qualified Infectious Disease Product (QIDP) for the prevention of gonorrhea in women.

EVOGUARD is funded in part by a recent strategic investment in Evofem by Adjuvant Capital, LLC.
