Duration of Effect of Acidform Gel on Vaginal pH

29 de outubro de 2020 atualizado por: Evofem Inc.

A Randomized, Placebo Controlled Pilot Study to Determine the Effect and Duration of Acidform Gel on Vaginal pH

The objective of this study was to determine the magnitude and duration of the reduction in pH (acidification) following a single dose of Acidform vaginal gel containing 3, 4, or 5 g compared with hydroxyethylcellulose placebo gel (4 g) or no treatment. Vaginal pH was measured 1 h, 6 h, 12 h, 24 h, then once daily for 7 days. In addition, the participants were assessed for an exploratory endpoint to the determine effect of one dose of Acidform gel (3, 4 or 5 g) or placebo gel (4 g) or no treatment, on asymptomatic bacterial vaginosis (BV).

Visão geral do estudo

Descrição detalhada

One hundred healthy volunteer women, 20 per each treatment arm, were treated with either Intravaginal Acidform Gel(IVAG), 5 g dose (GROUP A), Acidform gel, 4 g dose (GROUP B), Acidform gel, 3 g dose (GROUP C), Universal Placebo Gel (UPG), 4 g (GROUP D) or no treatment (GROUP E). For GROUPS A, B, C and D, treatment is defined as speculum exam plus instillation of Investigational Product (IP) or placebo gel. For GROUP E (control), no treatment is defined as speculum exam and no gel instillation.

At least 15 women in each group were of either African American or Hispanic ethnicity. Routine screening tests were performed on admission; and subjects assessed for BV via vaginal swabs obtained for grading by Amsel criteria.

A direct vaginal pH reading by research staff- was obtained before the speculum exam, as well as one hour, and six hours post-treatment (Day 0). At the one hour and six hour post treatment time points, the direct vaginal pH readings were taken on specimens collected from two different positions in the vagina, in case of incomplete distribution of the IP soon after administration. Both readings are included as data points. At the six hour timepoint, subjects were trained on self-collecting vaginal swabs and performing the vaginal pH test. At 12 hours post-treatment, subjects performed the vaginal pH test themselves using self-obtained swabs, and record their results for clinician review.

Subjects stayed overnight in the domiciliary unit, and vaginal pH and Amsel criteria was measured again by research staff at 24 (+/- 2) hours post-treatment before discharge on Day 1. The subjects were discharged with the appropriate pH testing supplies and diary. All women agreed to abstain from sexual intercourse, douching and use of any intravaginally applied products or devices until after their final study visit on Day 7.

Subjects measured their vaginal pH at 24 (+/-2) hour intervals for 5 days (Days 2-6) as outpatients and recorded the pH test results, and any change in vaginal comfort, in a provided diary. Subjects also recorded any activities engaged in from the abstinence criteria in the study exclusion list, if applicable, each day. On Day 7, subjects returned to the clinic with their diaries, had their vaginal pH and Amsel criteria determined by the clinic staff, and queried as to any vaginal discomfort (vaginal comfort assessment) over the course of the study, as self-recorded in their diaries.

The Effect of a Single Dose of Acidform Gel (3, 4 or 5 g), Placebo Gel (4 g), or no Treatment on Asymptomatic Bacterial Vaginosis (BV) Based on Amsel Criteria.
Prazo: Baseline (Day 0), Day 1 and Day 7
Amsel Criteria was used at baseline (day 0), compared to Day1 and Day 7 following the single dose of Acidform or placebo. Amsel criteria assessments consisted of Yes/No indications for the presence of each of the following: Vaginal pH> 4.5; Presence of thin, grayish white vaginal discharge; Positive wet prep; Positive whiff amine test. Based on the individual criteria, a derived overall result (positive/negative) was reported. Amsel Result was automatically calculated based whether or not subject is positive in three of the four criteria listed above.
