HIV InfectionsPhase 2NCT00006211
A Study of Capravirine Plus VIRACEPT Plus Two Nucleoside Reverse Transcriptase Inhibitors in HIV-Infected Patients Who Failed Previous Anti-HIV Treatments
A Phase 2 study testing Capravirine and Nelfinavir mesylate in people with HIV Infections, run by Agouron Pharmaceuticals at 1 site in United States.
Trial summary
The purpose of this study is to see if the addition of capravirine to VIRACEPT (nelfinavir mesylate) plus 2 nucleoside reverse transcriptase inhibitors (NRTIs) is an effective combination drug therapy for HIV patients who have failed a nonnucleoside reverse transcriptase inhibitor (NNRTI) therapy.

About this study
Official title: A Double-Blind, Randomized, Placebo-Controlled Study of Capravirine (AG1549) in Combination With VIRACEPT and Two Nucleoside Reverse Transcriptase Inhibitors in HIV-Infected Subjects Who Failed an Initial Nonnucleoside Reverse Transcriptase Inhibitor Containing Regimen
The purpose of this study is to see if the addition of capravirine to VIRACEPT (nelfinavir mesylate) plus 2 nucleoside reverse transcriptase inhibitors (NRTIs) is an effective combination drug therapy for HIV patients who have failed a nonnucleoside reverse transcriptase inhibitor (NNRTI) therapy.
Read the detailed description
[Note: As of 2/28/2001, due to toxicity studies and concern for safety, patients need to sign new informed consents. Patients who are taking capravirine and who currently have viral loads below 400 copies/ml may continue to take capravirine at 1400 mg twice daily. Capravirine will be discontinued in patients with viral loads greater than 400 copies/ml at their last visit and they will be switched to new therapies or continue with their background therapies as deemed appropriate by the investigators.] This study will take place in approximately 150 centers in the US, Canada, Europe, Australia, Argentina, and South Africa. Patients are randomized to 1 of 2 treatment groups and stratified by geographic sites (North American and non-North American), plasma HIV-1 RNA levels, and prior NNRTI use. Group 1 patients receive capravirine plus VIRACEPT plus 2 new NRTIs and Group 2 patients receive capravirine placebo plus VIRACEPT plus 2 new NRTIs. NRTIs will not be provided by the sponsor. Patients may remain on their assigned treatment for 48 weeks, with posttherapy follow-up occurring at 1 and 3 months. Assessments, done at various times throughout the study, include medical history, HIV antibody test, complete or symptom-directed physical examination, vital signs, height, weight, serum pregnancy test, hematology, chemistry, and recording of concomitant medications and adverse events. Other select assessments are performed at specified visits. Plasma samples for resistance testing and blood specimens for peripheral blood mononuclear cells (PBMC) are obtained at several times. The plasma samples and PBMCs may be used for viral drug resistance testing. Blood samples for quantitation of capravirine, VIRACEPT, and M8 (a metabolite of VIRACEPT) plasma concentrations are collected several times. Additional blood samples for analysis of drug concentrations may be requested depending on concomitant NRTIs or other medications. A Data Safety Monitoring Board monitors patient safety at prescribed intervals during the study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Capravirine and Nelfinavir mesylate in people with HIV Infections, run by Agouron Pharmaceuticals 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 9 inclusion and 7 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 24 Jun 2005. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
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 24 Jun 2005.
