  • 88.7% of Women Using Phexxi® (lactic acid, citric acid, and potassium bitartrate Vaginal Gel) Improved or Maintained their Sex Life According to Exploratory Data Collected During the Phase 3 AMPOWER Clinical Trial
  • Women in the Study Provided Data Measured by 10 Variables Ranging from the Ability to Climax to Interest in Having Sex
  • Phexxi is FDA Approved to Prevent Pregnancy

SAN DIEGO, April 19, 2022 /PRNewswire/ -- Evofem Biosciences, Inc., (Nasdaq: EVFM) today announced the Journal of Sexual Medicine, a peer-reviewed medical journal, published data collected from Evofem's Phase 3 AMPOWER clinical trial. Analysis of exploratory endpoints shows that 88.7% of women using Phexxi® (lactic acid, citric acid, and potassium bitartrate) reported improvement (n=44.7%) in or the maintenance (n=44%) of their sexual satisfaction. The publication can be found here:

"Phexxi offered the women in this study a non-hormonal, woman-controlled, on-demand contraceptive gel that clearly provided a unique set of positive benefits on their sexual health and enjoyment," said Dr. Todd Chappell, a clinical investigator and practicing obstetrician and gynecologist. "Publishing these data provides people and their health care providers with information about the impact Phexxi can have on sexual satisfaction."

The AMPOWER study enrolled healthy women between 18 and 35 who were sexually active with regular cyclic menses. More women reported satisfaction with Phexxi compared to their previous birth control method, and more than 93% percent of women in the study said they were likely to recommend Phexxi.

Investigators leading the trial asked 1330 women questions related to sexual satisfaction in the study. Specifically, patient-reported outcomes related to sexual satisfaction derived from the following:

  • A question related to the impact of the previous/current contraceptive on a woman's sex life
  • 10 questions from the Sexual Function Questionnaire related to the frequency of ten sexual problems
  • 19 questions from the Female Sexual Function Index related to lubrication

The Phase 3 AMPOWER clinical trial primarily sought to determine the ability of Phexxi to prevent pregnancy in 18 to 35-year-old women. In this trial, women's sexual satisfaction was listed as an exploratory endpoint, with the post-hoc exploratory analysis of sexual satisfaction.

"The AMPOWER study provided first-time insights on several issues related to sexual and reproductive health, and Evofem is grateful to all those who participated in our trial," said Saundra Pelletier, Chief Executive Officer, Evofem. "Intimacy is about so much more than reproduction. These data allow us to understand insights into women's sexual health and sexual satisfaction with the hope of ultimately improving their intimate experiences. Evofem will continue the research necessary to further scientific discourse and seek new and better ways to enhance sexual and reproductive health."
