Comparison of Two Dosing Regimens of GW433908/Ritonavir Versus Lopinavir/Ritonavir for 48 Weeks in HIV Patients Who Have Taken Protease Inhibitors and Experienced Virological Failure

June 23, 2005 updated by: GlaxoSmithKline

A Phase III, Randomized, Multicenter, Parallel Group, Open-Label, Three Arm Study to Compare the Efficacy and Safety of Two Dosing Regimens of GW433908/Ritonavir (700mg/100mg Twice Daily or 1400mg/200mg Once Daily) Versus Lopinavir/Ritonavir (400mg/100mg Twice Daily) for 48 Weeks in Protease Inhibitor Experienced HIV-Infected Adults Experiencing Virological Failure

The purpose of this study is to test 2 different dosing regimens of GW433908/ritonavir (RTV) versus lopinavir (LPV)/RTV when each is given with 2 active reverse transcriptase inhibitors (RTIs), in patients who have taken anti-HIV drugs without success.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will receive 2 dosing regimens of GW433908/RTV or LPV/RTV, in combination with 2 active RTIs, after failing their first or second protease inhibitor-containing regimen. Patients are required to be on therapy at time of screening and must remain on this therapy until Day 1.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years and older (Child, Adult, Older Adult)
