Evofem Biosciences® is dedicated to developing and commercializing innovative products to address unmet needs in women's sexual and reproductive health. Evofem is leveraging its proprietary vaginal pH modulator to develop product candidates for multiple indications, including the prevention of urogenital transmission of chlamydia and gonorrhea in women and recurrent bacterial vaginosis.

EVO100 – an investigational candidate for the prevention of urogenital chlamydia and gonorrhea in women

Our investigational drug candidate EVO100 vaginal gel is designed to reduce certain vaginal infections by:
  • Balancing vaginal pH, thereby maintaining healthy vaginal flora and creating an environment that is detrimental to the growth and proliferation of harmful bacteria
  • Using a different mechanism of action that may help to address drug resistance concerns
In October 2020, Evofem initiated EVOGUARD, a pivotal Phase 3 clinical trial to evaluate the safety and efficacy of EVO100 for the prevention of urogenital Chlamydia trachomatis and Neisseria gonorrhoeae infection in women. Top-line results are expected in 2022.

The Phase 2b AMPREVENCE study evaluating EVO100 for the prevention of chlamydia and gonorrhea met its primary and secondary endpoints, and the study showed that EVO100 was generally safe and well tolerated. Results of this double-blinded, placebo-controlled trial were presented at the 2020 STD Prevention Virtual Conference (view poster).

EVO100 has been granted Fast Track Designation for the prevention of chlamydia in women and is designated a Qualified Infectious Disease Product (QIDP) for the prevention of gonorrhea in women by the U.S. Food and Drug Administration.

Vaginal pH modulator for the prevention of recurrent Bacterial Vaginosis (BV)

This investigational drug candidate is in development to assess its ability to:
  • Kill BV-associated pathogenic bacteria, which has been demonstrated in vitro
  • Balance vaginal pH, thereby supporting normal vaginal flora and eliminating odor associated with BV

Clinical Trials

Chlamydia/Gonorrhea Prevention Clinical Trial

EVOGUARD is a double-blind, placebo-controlled Phase 3 clinical trial designed to assess the safety and efficacy of EVO100 vaginal gel to prevent Chlamydia trachomatis and Neisseria gonorrhea infection in women. Approximately 1,730 women who had a chlamydia or gonorrhea infection in the past 4 months will be enrolled at approximately 90 sites in the United States for a 4-month interventional period, followed by a 1-month follow-up period.
