Is this trial a fit for you?

Likely a good fit

Healthy individuals who have been enrolled in the progesterone sustained-release vaginal gel bioequivalence trials and provided informed consent.

Probably not a fit

Participants who are not in bioequivalence trials or who cannot provide consent may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will collect body composition data using the InBody S10 and link these measurements to pharmacokinetic parameters and adverse drug reactions observed in bioequivalence trials of a progesterone vaginal gel. The study analyzes how factors like muscle mass, fat, and lean body mass relate to drug handling in the body. It is an observational design, focusing on existing trial participants to explore potential associations. No intervention beyond data collection is planned.

Why it matters

Potential benefit: Findings could help tailor drug dosing to individual body composition in the future.

How similar studies have gone: Previous pharmacokinetic research has shown that body composition can influence drug behavior, supporting potential relevance of this approach.
