Patient enrollment is staged to allow study physicians to aggressively monitor patients for signs of toxicity. Initially, patients are admitted to a hospital or clinical research center for 2 weeks, where they initiate an [AS PER AMENDMENT 12/19/01: "8-drug regimen" is replaced by "7-drug regimen"] and undergo frequent physical exams and blood tests to assess [AS PER AMENDMENT 12/19/01: glucose levels], pharmacokinetics, virologic response, and toxicity. If investigators identify important drug interactions requiring modification of the combination regimen, or if there are early regimen-terminating toxicities, the trial will be halted to address these concerns. After 2 weeks, the patient is discharged to return home. Study personnel visit the patient's house twice a day for 6 more weeks to observe drug administration, and the patient continues to receive regular physical exams and blood tests. At the end of Week 24, all patients with plasma RNA levels of 10,000 copies/ml or less are offered the opportunity to continue their regimen to Week 48. Patients with plasma RNA levels above 10,000 copies/ml at Week 24 and patients who experience virologic rebound at or after Week 24 are taken off study unless the patient's family and the investigator feel it is in the best interest of the child to remain on study. [AS PER AMENDMENT 12/19/01: The 2-week hospital or GCRC stay is no longer required. A 2-day stay in a hospital or GCRC for the purpose of drug regimen training is recommended, but not mandatory. Study personnel visit the patient once a day for 6 weeks at an agreed upon location or by phone contact.
