Study Summary

This trial is testing two different formulations of a vaginal ring for their pharmacokinetics, or how the body processes the drug. The trial is double-blind, meaning that neither the participants nor the researchers know who is receiving which formulation.

Who is the study for?
This trial is for individuals assigned female at birth, aged 18-45, who are in good health and not currently pregnant or breastfeeding. Participants must have regular menstrual cycles, be HIV-negative with an intact uterus and at least one ovary, and agree to avoid certain medications that interact with the study drugs. They should not use hormonal contraceptives recently or have a history of significant allergies to the study products.Check my eligibility
What is being tested?
The trial is testing two different vaginal ring formulations containing Dapivirine and Levonorgestrel (IPM Ring-105 and IPM Ring-106) over a period of 90 days. It's designed to measure how these rings affect local tissues as well as their overall safety when used consistently.See study design
What are the potential side effects?
Potential side effects may include local irritation or discomfort where the ring is inserted, changes in menstrual bleeding patterns, possible increased risk of infections like UTIs or RTIs due to alterations in vaginal flora, and systemic effects related to levonorgestrel such as headaches or mood changes.
