Enfuvirtide/Current Protease Inhibitor Switch to PREZISTA (Darunavir)/Ritonavir + TMC125 in HIV Patients With Enfuvirtide Side Effects.

• Status: Completed
• Trial end date: 2008-10-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to examine the safety, tolerability, and effectiveness of darunavir/ritonavir combined with TMC125 when current protease inhibitor(s), Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTI(s)) and enfuvirtide are replaced by darunavir/ritonavir and TMC125 in HIV positive patients who can no longer tolerate enfuvirtide and are experiencing viral suppression. Other antiviral drugs in the regimen are to remain unchanged.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Tibotec, Inc
• Collaborator: Tibotec Therapeutics, a Division of Ortho Biotech Products, L.P., USA
• Treatments: Darunavir; Enfuvirtide; Etravirine; HIV Protease Inhibitors; Protease Inhibitors; Ritonavir

Criteria

Inclusion Criteria:

• Documented HIV-1 positive

• History of drug resistance or antiretroviral failure while receiving each of three drug classes: Nucleoside Reverse Transcriptase Inhibitors (NRTIs), Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) and (protease inhibitors) PIs

• On a PI containing regimen with enfuvirtide with HIV viral load (VL) < 400 copies/mL for 6 months or longer

• Continuously using the same PI regimen for 4 months prior to Screening

• Decline to continue enfuvirtide or their physician recommends discontinuation due to injection site reactions that persist despite optimal technique and training with available methods of administration or loss of sites for injection due to tissue nodules and hardening.

Exclusion Criteria:

• No use of any drug contraindicated in the current US package insert for PREZISTA (darunavir) or in the investigators brochure for TMC125

• No prior or current therapy with PREZISTA (darunavir) or TMC125

• No prior genotypic results demonstrating 3 or more darunavir resistance-associated mutations associated with diminished response to darunavir (V11I, V32I, L33F, I47V, I50V, I54L, I54M, G73S, L76V, I84V or L89V). Patients with > 3 darunavir resistance-associated mutations with available darunavir phenotypes, may be enrolled if the resistance phenotype demonstrates: Fold Change (FC) <10 to darunavir by PhenoSense GT (Monogram Biosciences) or FC <10 to darunavir by Antivirogram (Virco, BVBA) or FC <3.4 to darunavir by vircoTYPE (Virco BVBA)

• AST or ALT >5 times ULN

• Calculated CrCl < 30 ml/min.
