Evofem Biosciences Announces Last Patient Enrolled for AMPREVENCE, the Phase 2b Sexually Transmitted Infections Trial of Amphora

SAN DIEGO, April 23, 2019 /PRNewswire/ -- Evofem Biosciences, Inc. (NASDAQ: EVFM) ("Evofem"), a clinical stage biopharmaceutical company, today announced the completion of patient enrollment in AMPREVENCE, the Phase 2b clinical trial evaluating its lead product candidate Amphora®, a Multipurpose Vaginal pH Regulator™ (MVP-R), for the prevention of chlamydia and gonorrhea in women.

According to the CDC, chlamydia is the most frequently reported sexually transmitted bacterial infection in the U.S.  Rates of both gonorrhea and chlamydia climbed for the fourth consecutive year, with over 2.2 million cases reported in 2017.1

"We are eager to gain further insight into the ability of Amphora to prevent chlamydia and gonorrhea, and expect to report top-line AMPREVENCE data by the end of this year," said Saundra Pelletier, CEO of Evofem Biosciences.

AMPREVENCE, a double-blinded, placebo-controlled Phase 2b trial, enrolled approximately 850 women who had been treated for chlamydia or gonorrhea in the preceding four months. Subjects have been randomized to either Amphora or placebo vaginal gel treatment arms where they were asked to apply the study drug before engaging in sexual intercourse for four months. The primary and secondary endpoints of the study are the prevention of acquisition of urogenital Chlamydia trachomatis and Neisseria gonorrhea, respectively. Over 50 United States centers are participating in this unprecedented trial.

About Evofem Biosciences

Evofem Biosciences, Inc., is a clinical-stage biopharmaceutical company committed to developing and commercializing innovative products to address unmet needs in women's sexual and reproductive health. Evofem Biosciences aims to advance the lives of women by developing innovative solutions, such as woman-controlled contraception and potential protection from certain sexually transmitted infections ("STIs").  The Company is leveraging its proprietary Multipurpose Vaginal pH Regulator™ (MVP-R) platform to develop Amphora® (L-lactic acid, citric acid and potassium bitartrate) for birth control and prevention of urogenital acquisition of certain STIs. 

Amphora is designed to regulate vaginal pH within the normal range of 3.5 to 4.5. This maintains an acidic environment which is inhospitable to sperm as well as certain viral and bacterial pathogens associated with sexually transmitted infections but is integral to the survival of healthy bacteria in the vagina.
