12.2 Pharmacodynamics. Pharmacodynamic studies in humans have not been performed.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Pharmacokinetic studies in humans have not been performed. Systemic exposures of lactic acid, citric acid, and potassium bitartrate following vaginal administration of PHEXXI are not expected to lead to safety concerns.In vitro studies with commonly used vaginal preparations (miconazole, metronidazole, tioconazole, and product for maintaining normal vaginal pH) showed no significant effect on the pH or buffering capacity of PHEXXI.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. The efficacy of PHEXXI for the prevention of pregnancy was evaluated in multi-center, open-label, single-arm clinical trial in the United States (AMP002; NCT03243305). The study enrolled females of reproductive potential 18 to 35 years of age with regular menstrual cycles (21 to 35 days). The median age was 27.8 years. The racial distribution was 70.6% White, 23.7% Black or African American, 2.5% Asian, 0.4% American Indian or Alaska Native, 0.2% Native Hawaiian or Pacific Islander, and 2.7% other. Subjects agreed to engage in at least acts of heterosexual, vaginal intercourse per cycle. Subjects self-administered 5 gram dose of PHEXXI intravaginally up to one hour before each episode of intercourse for up to cycles. The primary efficacy endpoint was the 7-cycle typical use cumulative pregnancy rate as derived by Kaplan-Meier life-table analysis. total of 101 on-treatment pregnancies occurred in 1183 subjects contributing 4769 evaluable natural cycles. The 7-cycle cumulative pregnancy rate was 13.7% (95% CI: 10.0%, 17.5%), excluding cycles with back-up contraception, cycles <21 days or >35 days in length and cycles in which no intercourse was reported. The estimated Pearl Index, calculated based on data from the 7-cycle study, was 27.5 (95% CI: 22.4%, 33.5%).
