ClinicalTrials.gov Identifier:
NCT00052117
First received: January 22, 2003
Last updated: October 5, 2007
Last verified: October 2007
  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 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double-Blind
Primary Purpose: Treatment
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)
