A Study on Amprenavir in Combination with Other Anti-HIV Drugs in HIV-Positive Patients

Patrocinador(es) del estudio: National Institute of Allergy and Infectious Diseases (NIAID)
Números de identificación: NCT00000912, ACTG 398
  • Concluido

Propósito del estudio

To determine how many patients achieve plasma HIV-1 RNA concentrations of less than 200 copies/ml across 4 study arms by Week 24. To compare the time to quantifiable viremia (at least 200 copies/ml of plasma HIV-1 RNA) across the arms of the study. To compare safety and tolerance of treatment across the study arms.

Detalles del estudio

A number of studies both within and outside the ACTG have been initiated or are in development to try to address the issue of alternative treatments for patients who either do not achieve or lose virologic control while receiving protease inhibitors (PIs). Amprenavir (APV) is an attractive candidate to investigate as part of salvage regimens because: 1) it has substantial antiretroviral activity; 2) there are preliminary in vitro and in vivo data that suggest that resistance to this agent may be mediated in part by a unique mutation (I50V); and 3) its cross-resistance profile to the approved PIs is uncertain.Patients are selectively randomized to 1 of 4 study arms based on prior PI experience. Those randomized to Arms A, B, or C receive 2 PIs, 1 of which is amprenavir (APV), and those randomized to Arm D receive a single PI (APV) as part of their treatment regimen, as follows: Arm A: APV plus saquinavir soft gel capsule (SQVsgc) plus abacavir (ABC) plus efavirenz (EFV) plus adefovir (ADV). Arm B: APV plus indinavir (IDV) plus ABC plus EFV plus ADV. Arm C: APV plus nelfinavir (NFV) plus ABC plus EFV plus ADV. Arm D: APV plus placebo (NFV, IDV, or SQVsgc) plus ABC plus EFV plus ADV. All patients receive L-carnitine supplementation. All patients receive clinical physical assessments and laboratory testing during study as follows: Weeks 2, 4, and every 4 weeks thereafter. A primary analysis is performed after the last patient has reached 24 weeks. [AS PER AMENDMENT 3/2/00: At that time, all patients are unblinded to their original treatment assignment.] Patients who experience virologic failure are unblinded and may choose 1 of the following 3 options: Continue study medications open-label, permanently discontinue study medications, or selectively continue study medications [AS PER AMENDMENT 3/2/00: from the arm the patient was originally randomized to] and combine with other approved antiretroviral agents. [AS PER AMENDMENT 3/2/00: For patients adding didanosine (ddI) to their regimens, monitoring for the development of pancreatitis is crucial.] Final evaluations are required for those patients who are off drug during the immediate 8-week period following the last dose of study treatment. Beyond 8 weeks, they are followed for incidence of death, cancer, congenital anomalies, and permanent disabilities. [AS PER AMENDMENT 3/2/00: Gilead Sciences has terminated its U.S. development of ADV for HIV infection. Gilead will continue to supply ADV for patients in ACTG 398 until the study closes. Patients who are receiving ADV at the completion of the study may continue to access ADV through the Expanded Access Program, provided that the physician and patient have determined that continued use of ADV is beneficial.]
