Clinical Trial Summary

It is not known if the use of NuvaRing® alters these innate and inflammatory biomarkers of inflammation.

Hypothesis:

The hypothesis is that NuvaRing® will alter inflammatory biomarkers of inflammation, such as vaginal defensin and cytokine levels, resulting in an overall anti-inflammatory milieu in the vagina.

Specific aims of this study are to:

1. Determine biomarkers of inflammation, including defensins and cytokines, concentrations in women with normal vaginal flora (Nugent Score 0 - 3) before and after NuvaRing® use

2. Determine changes in the integrity of cervicovaginal epithelium and leukocytic concentration before and after treatment with NuvaRing®

3. Monitor for changes in the Nugent score before and after NuvaRing® use

4. Assess the antimicrobial activity of vaginal fluid before and after NuvaRing® use

5. Assess HIV infectivity ex vivo on biopsy specimens before and after NuvaRing® use

Methods This is a prospective, open-label, nonrandomized study. Participants will serve as their own controls. The Clinical Research Center of Eastern Virginia Medical School, Norfolk, Virginia, U.S.A. will be the only study site.

Clinical Trial Description

1. To complete specific aim #1, the investigators will use commercially available elisa kits to measure human defensins, inflammatory cytokines, and anti-inflammatory cytokines in vaginal fluid washings collected before and after use of NuvaRing.

2. To complete specific aim #2, the investigators will collect biopsies of the uterine cervix before and after NuvaRing use. Specimens will undergo histopathological measures for overall appearance, epithelial integrity, epithelial thickness, leukocyte infiltration, congestion, and edema. The investigators will quantitate the number of CD45+ and NFkB+ cells using immunohistology in the cervical epithelium. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
