Four-Drug Combination Treatment in Hiv-Infected Subjects Failing Therapy With Antiretroviral Regimens - Full Text View

Sponsor:	Pfizer
Information provided by:	Pfizer
ClinicalTrials.gov Identifier:	NCT00052117

Purpose

This is a 48 week study for HIV-infected patients who have failed several regimens including PI's, NNRTs and NRTIs. Patients will be randomly selected to be in 1 of 4 groups. Three of the 4 groups will contain capravirine in different doses combined with Kaletra and nucleosides and one of the groups will be a combination of Kaletra and nucleosides without the capravirine.

Condition	Intervention	Phase
HIV Infections	Drug: capravirine Drug: Kaletra Drug: 2 NRTIs	Phase II

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study
Official Title:	A Phase 2, Randomized, Double-Blind, Dose-Ranging Study Of Capravirine (AG1549) In Combination With Kaletra (Trademark) and At Least 2 Nucleoside Reverse Transcriptase Inhibitors in Hiv-Infected Subjects Who Have Failed Antiretroviral Regimens Containing Protease Inhibitors, Nonnucleoside Reverse Transcriptase Inhibitors, and Nucleoside Reverse Transcriptase Inhibitors

Further study details as provided by Pfizer:

Primary Outcome Measures:

To determine the optimal safe and effective dose of capravirine in combination with Kaletra plus at least 2 NRTIs

Secondary Outcome Measures:

the relationship of HIV baseline resistance (genotype and phenotype) to virologic outcome
the population pharmacokinetics of capravirine and lopinavir/ritonavir (Kaletra) using mixed-effects modeling
the pharmacokinetic drug-drug interactions between capravirine and Kaletra and selected concomitant medications
changes in subject-reported health status and HIV symptoms using the Medical Outcomes Study - HIV Health Survey (MOS-HIV) and the Symptoms Distress Module (National Institute of Allergy and Infectious Diseases Adult AIDS Clinical Trials Group)
