HIV-1 Infection
Conditions
Brief summary
The purpose of this phase III study is to evaluate the efficacy, safety and tolerability of UB-421 monotherapy in suppressing viral rebound in HIV-1 infected adults undergoing antiretroviral treatment interruption.
Detailed description
This is an open-label, Phase III study to evaluate the efficacy, safety and tolerability of UB-421 monotherapy in suppressing viral rebound while replace HAART in virally suppressed HIV-1 infected adults. In this study, approximately 375 subjects on stable HAART treatment will be randomized to receive either continuing HAART treatment alone (Cohort 1) or UB-421 as the monotherapy (Cohort 2) in 1:2 ratio. For Cohort 1, subjects will receive current standard HAART treatment as the active control group. For Cohort 2, UB-421 will be administered to enrolled subjects without HAART treatment in the Cohort 2 during the 26-week treatment period. After treatment period, both cohort 1 and cohort 2 enter 22-week follow-up period.
Interventions
Subjects will receive 13 doses of the UB-421 by intravenous infusion at 25 mg/kg bi-weekly (Cohort 2, 26 weeks).
Subjects will receive current standard HAART treatment as the active control group.
