About this study

Official title: Randomized Controlled Trial of 6% Cellulose Sulfate Gel and the Effect on Vaginal HIV Transmission

The purpose of the study is to determine the effect of cellulose sulfate on the transmission of HIV to women via vaginal intercourse. The secondary objectives are the effect on the transmission of gonorrhea and chlamydia via the same route.

The study hypothesis is that there will be no effect.

Read the detailed description

Despite the availability of an effective HIV prevention method, i.e. the condom, the epidemic continues growing. There is thus an urgent need for additional HIV prevention methods. One of the possibilities is the use of microbicides, i.e. chemical products which may be used in the vagina or rectum with the potential to prevent HIV infection.

Cellulose sulfate is an HIV entry inhibitor with an in vitro effect on N. gonorrhoeae (NG) and C. trachomatis (CT) and other sexually transmitted organisms.

The study assess its effect on the vaginal transmission of HIV, NG and CT among women at high risk of heterosexual STI infection (defined as having had more than two partners in the last three months and an average of three sexual acts per week).

The study is randomized, triple-blinded, placebo controlled.

The record says: stopped early, as of the sponsor's last update on 28 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in India, Benin, South Africa, Uganda. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was stopped early (reason given: IDMC recommendation). Results are not available in the source record.

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?

Combined incidence of HIV-1 and HIV-2 in the study. (time frame: 1 year). 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 NCT00153777, which also lists 10 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 28 Aug 2015.
