Evofem Biosciences Completes Phase 3 Clinical Trial of Amphora for Prevention of Pregnancy
-- Company Remains on Track for AMPOWER Top-line Results in Late 2018 --

SAN DIEGO, Nov. 8, 2018 /PRNewswire/ -- Evofem Biosciences, Inc., (NASDAQ: EVFM) ("Evofem" or the "Company") today announced the last patient has completed her last visit in AMPOWER, the second Phase 3 clinical trial of Amphora® (L-lactic acid, citric acid and potassium bitartrate), its lead Multipurpose Vaginal pH Regulator (MVP-R) product candidate, for the prevention of pregnancy.

Amphora is an investigational, first-in-class MVP-R designed to give a woman control over some of the most intimate issues of her life and health. This non-hormonal, non-systemic vaginal gel is being developed for woman-controlled birth control as well as prevention of certain sexually transmitted infections (STIs).

"We have long recognized the need for well-studied birth control options that will address the needs of women who do not wish to become pregnant but will not or cannot use hormonal birth control methods," said Bassem Maximos, MD, MPH, FACOG, a practicing obstetrician/gynecologist and principal investigator for AMPOWER. "An FDA-approved hormone-free birth control product that is both on-demand and woman-controlled would represent a new and important option in the gynecologist's arsenal, unlike anything that is available today."      

"Widespread demand for participation in this important Phase 3 clinical trial allowed us to successfully enroll approximately 1,400 women, the last of whom has just completed her final study visit.  Achieving this critical milestone brings us another step closer to moving forward with data analyses, keeping us on track for top-line AMPOWER data by the end of this year," said Brandi Howard, PhD, Evofem's Senior Vice President of Global Clinical Development & Medical Affairs.

"Assuming positive results, Evofem will re-submit the Amphora New Drug Application in the second quarter of 2019," said Saundra Pelletier, Chief Executive Officer of Evofem Biosciences. "Subject to FDA approval, we expect to commercialize Amphora in January 2020 as the first and only non-hormonal, woman-controlled prescription birth control method in the U.S."

"We would like to thank our investigators and site coordinators, as well as the patients who participated in this important study, which will provide critical insight on the potential of Amphora as a non-hormonal birth control method," Dr. Howard continued. "This first-in-class product has the potential to be a paradigm-shifting new option for millions of women in the U.S., including the 16.5 million women who do not wish to become pregnant and currently use no form of birth control.1"

Women who do not use any contraceptive method but who are not trying to become pregnant have an 85% risk of experiencing an unintended pregnancy within one year.1

Pelletier continued, "Most women don't have sex every day, yet the majority of available options require a daily dose of hormones.  It is time that women have access to a product designed for them, that empowers them with a safe and effective non-hormonal birth control option, that they use only when needed."

About Amphora
Amphora® (L-lactic acid, citric acid, and potassium bitartrate) is an investigational non-hormonal gel 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.

Evofem expects top-line data in December 2018 from AMPOWER, its Phase 3 clinical trial evaluating Amphora for the prevention of pregnancy. This single-arm, open-label trial enrolled approximately 1,400 women aged 18-35 who are at risk of pregnancy at 112 U.S. centers. The primary endpoint of the study is pregnancy prevention over seven cycles of use.

The Company is actively enrolling AMPREVENCE, a double-blinded placebo-controlled Phase 2b clinical trial of Amphora to prevent urogenital acquisition of Chlamydia trachomatis (primary endpoint) and Neisseria gonorrhea (secondary endpoint) in women.  This study is designed to enroll 844 women at approximately 50 centers in the United States for a four-month interventional period and subsequent one-month follow-up period.

The CDC recently reported that rates of chlamydia, the most frequently reported bacterial sexually transmitted disease (STD) in the U.S., and gonorrhea have climbed for the fourth consecutive year in the United States.  Last year, nearly 2.3 million U.S. cases of these STDs were diagnosed, according to preliminary data, an increase of over 200,000 cases as compared with 2016.2 There are currently no FDA-approved products for either of these STDs.
