About this study

Official title: Phase I Study of the Safety and Persistence of 0.1% UC-781 Vaginal Gel in HIV-1 Seronegative Women

Vaginal microbicides are compounds that may protect women from HIV and other sexually transmitted infections (STIs). This study will determine the safety of the microbicide UC-781 by comparing the effects of keeping the microbicide in the vagina for different lengths of time.

Read the detailed description

Vaginal microbicides are compounds applied to the inside of the vagina that may protect women against vaginal transmission of HIV and other STIs. This study will evaluate the safety of the vaginal microbicide UC-781. Studies have shown UC-781 to be an effective inhibitor of HIV-1 reverse transcriptase. UC-781 has been tested in animal models and in Phase I and II studies in humans. The results of these studies indicated that cervical tissue was fully protected from different variants of HIV. The purpose of this study is to assess the incidence of epithelial disruption and inflammation in the cervix, vagina, and vulva of healthy HIV uninfected women after a single exposure to UC-781 vaginal gel. This study will compare the results of leaving the microbicide in the vagina for varying lengths of time.

The duration of this study is approximately 35 days. Participants in this study will be randomly assigned to one of eight groups, and all participants will receive a single exposure of UC-781 or placebo gel. There will be five total study visits, including the screening and study entry visits. Screening will occur approximately 10 days prior to the study entry visit. At study entry, a single application of microbicide or placebo gel will be inserted for 0, 2, 4,or 8 hours in the vagina. Length of exposure time will differ, depending on which group a participant has been randomly assigned to. Following vaginal exposure to the microbicide, the microbicide will be rinsed off. Vaginal secretions will be collected to test antiviral activity against HIV and assess the amount of microbicide remaining in the vagina. Visits 3 through 5 occur at approximately 24 to 48 hours, 6 to 8 days, and 25 to 35 days following study entry.

At all visits, participants will be asked to complete a questionnaire and undergo a pelvic exam, STI tests, and vital signs measurements. Blood and urine collection will occur at each visit. On selected visits, a colposcopy will be conducted and participants will be interviewed regarding product acceptability, in addition to other measures. Between selected visits, participants will be asked to maintain sexual abstinence or use condoms.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing UC-781 in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Mar 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local and systemic safety of a one-time dose of UC-781 0.1 % gel for vaginal use at different durations of exposure in HIV uninfected women (time frame: Throughout study). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00441909, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Mar 2009.
