Evofem Presents Data Detailing Fewer Urinary Tract Infections in Women Using Phexxi in the Phase 3 AMPOWER Clinical Trial

• 5.8% of Women in the AMPOWER Trial Experienced an On-Study Urinary Tract Infection Compared to 11% in the General Population
• The Post hoc Analysis will be Presented at the 2022 American College of Obstetricians and Gynecologists (ACOG) Annual Meeting in San Diego, CA on
  May 7, 2022

SAN DIEGO, May 6, 2022 /PRNewswire/ -- Evofem Biosciences Inc., (Nasdaq: EVFM) today announced that new data from the Phase 3 AMPOWER clinical trial of Phexxi^® (lactic acid, citric acid, and potassium bitartrate) showed that women enrolled in the AMPOWER trial had fewer urinary tract infections (UTIs) compared to the general population.

Dr. Bassem Maximos, the lead author of the poster will present this new data set at the American College of Obstetricians and Gynecologists (ACOG) Annual Meeting on Saturday, May 7, 2022. Details of the presentation and data can be found here: 2022 ACOG Annual Clinical and Scientific Meeting: Meeting Details (pathable.com).

“In this post hoc analysis women who used Phexxi experienced significantly fewer UTIs compared to the general population,” said Dr. Bassem Maximos, lead author of the study and Head of Maximos Ob/Gyn in League City, Texas. “These data provide insights worthy of further investigation to determine if Phexxi has an impact on UTIs in women.”

AMPOWER was a Phase 3, single-arm, multicenter study that evaluated the efficacy and safety of Phexxi for the prevention of pregnancy.

Of the 1339 women who self-administered at least one dose of Phexxi and were included in the safety population, 77 (5.8%) experienced an on-study UTI. Of the 77 women who experienced UTIs, one woman experienced an event that was classified as “urinary tract infection bacterial"; the remaining 76 women had events classified as “urinary tract infection”. Adverse events (≥2%; N=1330) were congruent with the results from the overall study findings.

“The Phase 3 AMPOWER study continues to provide data showing a larger and positive impact on a woman’s sexual, reproductive, and general health,” said Saundra Pelletier, Chief Executive Officer, Evofem. “Later this year will read out top-line data from our registrational Phase 3 EVOGUARD trial investigating Phexxi for the prevention of chlamydia and gonorrhea, which, if approved, could further expand Phexxi’s opportunities to protect women’s health.”
