Brief Summary

Randomized, controlled, double-blinded, cross-over trial of 60 HIV-infected women recruited from general medical clinics, family planning clinics, groups/organizations working with persons living with AIDS to assess product safety, effect on genital tract HIV shedding, and product acceptability with vaginal use of Carraguard gel among HIV-infected women.

Outcome Measures

Primary Outcomes (3)

• Safety: irritation, effect on vaginal flora, vaginal epithelial disruption determined by visual inspection (Day 7, 14) and colposcopic inspection(Day 7); other adverse effects, which may include UTI or other unforeseen problems (Day 7, 14).

• Genital tract HIV: measured using samples collected by CVL (Day 7, 14) and vaginal swab (Day 7, 14).

• In good health as determined by medical history, physical examination and results of any laboratory screening test, and the discretion of the clinical staff
• Able to achieve a score of 80% or better on true-false test of key study concepts. If women score less than 80% the first time they take the test, they may repeat the test at least one day later

You may not qualify if:

• CD4 count \<50
• Pregnancy or desire to become pregnant in the next 3-4 months
• Delivery, miscarriage, or abortion within six weeks prior to study enrollment

• Concurrent participation in another trial of a vaginal product
• History of sensitivity or allergy to latex products (including gloves)
• Presence of epithelial disruption of the labia or genital mucosa visible to the naked eye at enrollment1
• Positive test for gonorrhea, chlamydial infection, trichomoniasis, or evidence of untreated syphilis (see section 5.19). Participants with positive tests must be treated and have a negative test of cure to be eligible for enrollment.1
