About this trial

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.

Treatments tested in this trial

  • Live Biotherapeutic Product L. jensenii 1153-1666

    Drug

    The vaginally administered MucoCept-CVN contains Lactobacillus jensenii 1153-1666, a natural component of the human vaginal microbiota that has been modified to continuously express the potent HIV entry inhibitor modified-cyanovirin-N (mCV-N) right at the site of infection. MucoCept-CVN is supplied as a prefilled vaginal applicator containing Lactobacillus jensenii 1153-1666, a modified strain of L. jensenii 1153 by integrating a modified cyanovirin-N gene into its chromosome to enhance the strain's ability to inhibit HIV. Each applicator contains 200 mg of MucoCept-CVN powder (1 x 109 CFU), and an inactive preservation matrix.

  • Placebo

    Drug

    Each placebo applicator contains 200 mg of placebo powder comprising the same inactive ingredients of the preservation matrix as the study product.
