T-20 With Anti-HIV Combination Therapy for Patients With Prior Anti-HIV Drug Treatment and/or Drug Resistance to Each of the Three Classes of Approved Anti-HIV Drugs

A Phase III Open-Label, Randomized, Active-Controlled Study Assessing the Efficacy and Safety of T-20 (HIV-1 Fusion Inhibitor) in Combination With an Optimized Background Regimen, Versus Optimized Background Therapy Alone, in Patients With Prior Experience and/or Prior Documented Resistance to Each of the Three Classes of Approved Antiretrovirals (Nucleoside Reverse Transcriptase, Non-Nucleoside Reverse Transcriptase and Protease Inhibitors)

Brief summary

The purpose of this study is to compare the change in viral load (amount of HIV in the blood) of patients who receive T-20 with selected anti-HIV drugs to that of patients who receive only selected anti-HIV drugs.

Detailed description

Eligible patients remain on their pre-study regimen until baseline. An OB regimen is chosen by the physician and patient based on the patient's prior treatment history, prior and current laboratory abnormalities, the screening GT/PT antiretroviral resistance testing, and any prior GT/PT antiretroviral resistance (if available). The drugs in the OB regimen are chosen from among the currently approved antiretrovirals and permitted newly approved/investigational antiretrovirals available in the countries where the study is implemented, and must consist of 3 to 5 drugs, including no more than 1 newly approved/investigational agent. Patients are stratified with respect to viral load and use (versus non-use) of any of the allowed newly approved/investigational antiretrovirals. Patients are randomized to receive 1 of the following 2 treatments for 48 weeks: OB or OB plus T-20. Patients are followed to assess viral load, safety, antiretroviral resistance, T-20 pharmacokinetics, and quality of life. At the end of 48 weeks of treatment patients are allowed to (a) roll over and receive OB plus T-20 (for patients receiving OB regimen alone) or (b) continue taking OB plus T-20 (for patients already receiving OB plus T-20), for an additional 48 weeks (plus 4 weeks safety follow-up period), or until 12 weeks after commercial availability of T-20 in the country in which they are treated, whichever comes first. All patients are followed in this study for a maximum of 100 weeks from their initial baseline visit date.
