Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The goal of this clinical trial is to assess the safety and pharmacokinetics of YASO GEL in healthy adult participants. This is a first-in-human study designed to understand how the gel is absorbed and distributed in plasma and vaginal fluid, and to evaluate the methods used to measure drug levels in humans.
The main questions the study aims to answer are:
What is the preliminary safety and tolerability of YASO GEL at a subtherapeutic 0.7% dose?
How is YASO GEL absorbed and distributed, and does sexual activity affect its pharmacokinetics?
Participants will:
Receive an application of YASO GEL.
Provide blood and vaginal fluid samples for pharmacokinetic analysis.
Participate in a sub-study evaluating the impact of sexual activity on safety and drug exposure.
Additional information on product acceptability, adherence, and exploratory laboratory analyses will be collected to inform the design of future studies.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study initiates with a first-in-human lead-in study using a subtherapeutic 0.7% dose of YASO GEL. The study aims to provide a preliminary assessment of PPCM pharmacokinetics in plasma and vaginal fluid, and to validate a bioanalytical assay to be used to measure efficacy in both the Phase 1 and sub studies. Data from this study will help ensure that pharmacokinetic sampling is adequate for subsequent clinical trials and will provide initial safety information to support a Phase 1 study.
The subsequent randomized double-blind Phase 1 study will use a therapeutic 2.0% dose of YASO GEL administered once in Stage 1 of the Phase 1 study and once daily for 7 days in Stage 2 of the Phase 1 study. The Phase 1 study is designed to provide comprehensive baseline safety and pharmacokinetic data in a dose response manner. As such, it is important to assess the genitalia (vulva, perineum and vagina for female participants and penis, scrotum, and perineum for male participants) after each dose for safety, initially with single dose and then with repeated dosing. Because it is anticipated that a coitally-dependent product will be applied prior to each act of coitus, and individuals may have coitus more than once a day, future studies will evaluate more frequent dosing and further characterize the YASO GEL safety profile.
Secondarily, acceptability and adherence data will be collected to inform future product design and patient education. Exploratory endpoints include assessment of vaginal fluid samples for vaginal microbiome, soluble immune mediators, ex-vivo contraceptive activity and anti-microbial activity against both HIV and Ng.
A sub-study is included to evaluate the impact of coitus on safety and pharmacokinetics of YASO GEL use. This study will also collect acceptability and adherence data to inform future product design and patient education. Vaginal fluid samples will be assessed for contraceptive activity and ex vivo anti-microbial activity against both HIV and Ng, in an exploratory fashion to inform future study design.
The study will include healthy adult participants. Female participants will apply the gel internally in all studies. Male participants will apply the gel externally in the Lead-in and Phase 1 studies and be exposed to the gel in the coital sub-study. The results from this study will guide the design of future studies and help establish the safety and efficacy profile of YASO GEL in humans.

Allocation Method
RANDOMIZED
Intervention Model
PARALLEL
This first-in-human study consists of three parts. A 6-participant open-label lead-in cohort will receive a single low dose of the investigational contraceptive to assess initial safety and tolerability. The main Phase 1 study is a randomized, double-blind, parallel-group trial enrolling 32 participants, conducted in two stages: Stage 1 participants receive a single full-strength dose with 21-day follow-up, and Stage 2 participants receive daily full-strength doses for 7 days with 28-day follow-up. A 12-participant non-randomized coital sub-study will further assess safety and exploratory endpoints in the context of sexual activity, with and without use of the investigational product. Participants in the randomized Phase 1 portion remain in their assigned intervention arm throughout the study.
