Phase 1 Randomized Double-Blind Placebo-Controlled Safety Study of MucoCept-CVN (Lactobacillus Jensenii 1153-1666) Administered Vaginally to Healthy Women
Craig Cohen, MD, MPH
Summary
MucoCept-CVN uses a Lactobacillus strain native to the human vagina that is modified into a live biotherapeutic product (LBP) that continuously expresses a potent anti-HIV drug. If research shows that MucoCept-CVN is safe and effective, it could become a self-renewing, female-initiated prevention product for women that promotes vaginal health and provides protection from HIV. The goal of this first-in-human Phase 1 dose-ranging, randomized, placebo-controlled study of MucoCept-CVN is to collect data on safety, colonization, changes to the vaginal microbiota and clearance of the strain with antibiotics. Twelve healthy women will be enrolled and take either one or three doses of MucoCept-CVN or placebo, and a week later will receive antibiotics to clear the Lactobacillus strain. If research shows that MucoCept-CVN is safe and effective, it could become a self-renewing, long-acting, female-initiated prevention product for women that promotes vaginal health and provides protection from HIV.
Description
The goal of this first-in-human Phase 1 dose-ranging, randomized, placebo-controlled study is to collect critical data needed to advance the clinical development of MucoCept-CVN, specifically (1) understanding factors that influence vaginal colonization by L. jensenii 1153-1666, including dose and endogenous vaginal microbiota; and (2) pharmacokinetic, tissue and systemic effects of L. jensenii 1153-1666, such as adverse events (AE) and findings in colposcopy and vaginal biopsy, and (3) changes to the vaginal microbiota. We also need to show that (4) L. jensenii 1153-1666 can be sufficiently c…
