SAN DIEGO, May 6, 2022 /PRNewswire/ — Evofem Biosciences Inc., (Nasdaq: EVFM) today announced that new data from the AMPOWER Phase 3 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) than the general population.



dr. Bassem Maximethe senior poster author will present this new dataset 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: ACOG 2022 Annual Clinical and Scientific Meeting: Meeting Details (pathable.com).


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


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


Of the 1,339 women who self-administered at least one dose of Phexxi and entered the safety population, 77 (5.8%) experienced a UTI during the study. Of the 77 women who experienced UTIs, one woman experienced an event classified as “bacterial urinary tract infection”; the remaining 76 women had events classified as “urinary tract infection”. Adverse events (≥2%; N=1330) were consistent with the results of the overall study findings.


“The Phase 3 AMPOWER study continues to provide data showing a greater and positive impact on a woman’s sexual, reproductive and general health,” said Saundra Pelletier, Managing Director, Evofem. “Later this year, we will read key data from our EVOGUARD Phase 3 registration trial of Phexxi for the prevention of chlamydia and gonorrhea, which, if approved, could further expand the opportunities for Phexxi. to protect women’s health.
