Evofem Completes Enrollment in EVOGUARD Phase 3 Clinical Trial of EVO100 for the Prevention of Chlamydia and Gonorrhea in Women

SAN DIEGO, March 4, 2022 /PRNewswire/ — Evofem Biosciences Inc., (Nasdaq: EVFM) today announced that it has completed its listing in EVOGUARDthe registrational Phase 3 clinical trial evaluating EVO100 (the investigational name of Phexxi® (lactic acid, citric acid, potassium bitartrate)) for two potential new indications: prevention of chlamydia infection in women and prevention of urogenital gonorrhea infection in women.

The design of the clinical trial initially envisaged a recruitment of 1730 participants. Due to the high level of demand to participate in the study, researchers recruited 1,903 participants, providing the opportunity for a more complete understanding of the trial data and results.

Main data of EVOGUARD are expected in the second half of 2022.

“I see a significant increase in the number of chlamydia and gonorrhea infections in my patients,” said Dr. Todd Chappell, EVOGUARD trial investigator and practicing obstetrician and gynecologist. “There is a significant need for new effective and safe ways to prevent these infections, and Phexxi, a potential preventative option against these contagious diseases, may offer women some form of protection against these infections.”

The CDC estimates that 4.0 million and 1.6 million new cases of chlamydia and gonorrhea, respectively, occurred in 2018 alone..1 The number of reported cases is lower than the total estimated number because those infected are often unaware of their infection and do not seek treatment. Almost 60% of women infected with chlamydia have no symptoms.2 Chlamydia is the most commonly reported bacterial infection in the United States and can infect both men and women. It can cause serious and permanent damage to a woman’s reproductive system and make it difficult or impossible for a woman to become pregnant later in life.

Chlamydia and gonorrhea are thought to be responsible for one-third to one-half of pelvic inflammatory disease (PID) cases. PID can cause serious long-term problems, including infertility, ectopic pregnancy, and chronic pelvic pain.3

The completion of registration comes less than a month after the U.S. Food and Drug Administration (FDA) granted a Qualified Infectious Disease Product (QIDP) designation to EVO100 (the investigational name of Phexxi) for the prevention of urogenital chlamydial infection in women. The QIDP designation is intended to encourage the development of new products for the treatment of serious or life-threatening infections. A drug or product in development that receives this designation qualifies for an additional five years of market exclusivity after FDA approval for that indication.

“Complete registration for EVOGUARD marks an important milestone for Evofem and underscores our continued efforts to evaluate this potential product, the first and only in its class, in women for the prevention of chlamydia and gonorrhea infections,” said Saundra Pelletier, CEO of Evofem Biosciences. “As we speak with women and observe the market environment, we recognize the need to educate the public about these two sexually transmitted infections and strive to seize this opportunity and expand our role to help women control and protect their sexual health. If approved, Evofem may have an impact beyond preventing unplanned pregnancies and creating a significant new market opportunity. »

The FDA previously granted EVO100 Fast Track designation for the prevention of chlamydia and gonorrhea, and in 2017 granted QIDP designation to EVO100 for the prevention of gonorrhea in women.

Evofem would like to thank all those who participate and lead the EVOGUARD trial, and all other ongoing research sponsored by Evofem.
