Testing a vaginal treatment to help prevent HIV in women

Phase 1 Randomized Double-Blind Placebo-Controlled Safety Study of MucoCept-CVN (Lactobacillus jensenii 1153-1666) Administered Vaginally to Healthy Women

NIH-funded research University of California, San Francisco · NIH-10999145

This study is testing a new vaginal treatment called MucoCept-CVN, which uses a special strain of good bacteria to help improve vaginal health and lower the risk of HIV transmission, and it's looking for healthy women to try it out and see how well it works.

What this research studies

This research investigates a new vaginal treatment called MucoCept-CVN, which contains a bioengineered strain of Lactobacillus jensenii. The treatment aims to enhance vaginal health and reduce the risk of HIV transmission by delivering a potent HIV entry inhibitor directly to the site of potential infection. The study will involve healthy women who will receive either the treatment or a placebo in a randomized manner, allowing researchers to assess safety and effectiveness. Participants will help provide important data on how well the treatment colonizes the vaginal area and its pharmacokinetics.

Who could benefit from this research

Good fit: Ideal candidates for this research are healthy women who are at risk of HIV exposure.

Not a fit: Patients who are not at risk of HIV or those with existing HIV infections may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a novel method for women to prevent HIV transmission, significantly impacting public health.

How similar studies have performed: Preclinical studies have shown promising results with similar approaches, indicating a potential for success in human trials.
