A Phase II, 24-Week, Open-Label Study Designed to Evaluate the Pharmacokinetics, Safety, Tolerability, and Efficacy of Novel Combination Therapy With Videx (Didanosine), Zerit (Stavudine), Viramune (Nevirapine), and MKC-442 (With or Without Hydroxyurea) for the Treatment of HIV-1 Infection in Non-Nucleoside Reverse Transcriptase Inhibitor Naive Patients Who Failed Previous Protease Inhibitor Treatment

The Safety and Effectiveness of Didanosine Plus Stavudine Plus Nevirapine Combined With MKC-442 in HIV-Infected Patients Who Have Not Had Success With Protease Inhibitors

Brief Summary

The purpose of this study is to see if it is safe and effective to give a new anti-HIV drug combination to HIV-infected patients who have never taken nonnucleoside reverse transcriptase inhibitors (NNRTIs) and who have failed to respond to protease inhibitors (PIs). The drug combination will contain didanosine (ddI) plus stavudine (d4T) plus nevirapine (NVP) plus MKC-442. Hydroxyurea (HU) may be added.

Detailed Description

Patients receive a regimen of didanosine, stavudine, nevirapine, and MKC-442 for 24 weeks. Throughout the study, patients are evaluated for changes from baseline in plasma HIV-1 RNA levels and lymphocyte subsets and for development of adverse events and toxicities. Patients who experience virologic failure have the option of adding hydroxyurea to their treatment regimen or discontinuing from the study. After Week 24, patients with documented virologic response may continue treatment with didanosine, stavudine, nevirapine, and MKC-442, and, if applicable, hydroxyurea until a change in virologic status occurs (i.e., the patient experiences virologic failure). Follow-up visits are conducted every 4 to 12 weeks until permanent discontinuation from the study.
