HIV-1 Infection in Adults (Asymptomatic)
Conditions
Keywords
HIV-1, CD4, antibody, immunotherapy
Brief summary
The purpose of this Phase I study is to determine whether the antibody (UB-421), targeting the HIV-1 receptor on the CD4 molecule (domain 1) of T-lymphocytes and monocytes, is safe and well tolerated when administered to asymptomatic HIV-1 infected adults by intravenous infusion and to assess pharmacokinetic parameters of the antibody in blood and on cells. The neutralizing activity of UB-421 blocks HIV-1 from binding to its receptor on CD4-positive cells; thus, UB-421 functions as an immunotherapeutic intervention to prevent HIV-1 infection.
Interventions
Single intravenous infusion at day 0 of a liquid dose of 1, 5, 10 or 25 mg/kg body weight.
