Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the efficacy of enfuvirtide (Fuzeon) added to HAART compared to treatment with HAART alone in achieving and maintaining viral load suppression.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study consisted of two phases. In the Induction phase patients were randomized at Baseline 1 (BL1) in a 1:2 ratio to receive:

* I1: HAART or
* I2: Enfuvirtide (90 mg twice a day) + HAART.

Participants who achieved viral suppression \< 50 copies/mL by week 24, confirmed by week 28 or earlier, qualified to enter the Maintenance Phase which started at Baseline 2 (BL2), four weeks after confirmation of response. The Maintenance Phase consisted of three treatment groups:

* M1: HAART continued (patients from I1)

Patients on ENF+HAART (I2) were re-randomized (at a 1:1 ratio) at BL2 to:

* M2: Enfuvirtide stopped and HAART continued
* M3: Enfuvirtide + HAART continued.

The duration of the Maintenance Phase was from BL2 up to 48 weeks after BL1. BL2 could start at the earliest at Week 12 and at the latest Week 32.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ENF + HAART

Participants received Enfuvirtide (ENF) 90 mg administered by subcutaneous injection twice a day for up to 48 weeks in addition to an oral highly active antiretroviral treatment (HAART) regimen for up to 48 weeks.

Group Type EXPERIMENTAL

Enfuvirtide

Intervention Type DRUG

90 mg subcutaneous injection twice a day

Highly active antiretroviral treatment (HAART)

Intervention Type DRUG

An oral HAART regimen of 3-5 antiretrovirals was chosen by the physician and patient, based on the patient's prior treatment history and genotypic antiretroviral resistance testing.

HAART

Participants received an oral highly active antiretroviral treatment (HAART) regimen, consisting of 3-5 antivirals for up to 48 weeks.

Group Type ACTIVE_COMPARATOR

Highly active antiretroviral treatment (HAART)

Intervention Type DRUG

An oral HAART regimen of 3-5 antiretrovirals was chosen by the physician and patient, based on the patient's prior treatment history and genotypic antiretroviral resistance testing.
