L-697,661 is a newly identified compound that inhibits HIV replication (reproduction and growth) in cell culture. It works together with AZT against HIV.

Read the detailed description

L-697,661 is a newly identified compound that inhibits HIV replication (reproduction and growth) in cell culture. It works together with AZT against HIV.

Part 1: Twelve patients are randomly assigned to one of two groups. Group 1 patients receive AZT for 7 days, followed by AZT plus L-697,661 with food for 56 days. Group 2 patients receive no drug for 7 days, followed by L-697,661 with food for 56 days. Antipyrine is administered 1 hour prior to study drug on days 8, 22, and 35.

Part 2: Fifteen patients receive L-697,661 with food, for 8 weeks. Therapy with L-697,661 may be extended beyond 8 weeks for up to 24 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing L-697,661 and Zidovudine in people with HIV Infections, run by Merck Sharp & Dohme LLC at 5 sites 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 5 inclusion and 24 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 30 Jul 2008. 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 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. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000628, which also lists 3 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 30 Jul 2008.
