Detailed Description:

In preclinical studies carried out in humanized mice and non-human primates, 3BNC117 alone or in combination with other neutralizing antibodies led to protection from HIV-1 or SHIV infection and also to sustained suppression of HIV-1 plasma viremia. The aims of this protocol are to evaluate the safety, tolerability and pharmacokinetics profile of 3BNC117 in both HIV-infected and HIV-uninfected subjects,and its antiretroviral activity in HIV-infected subjects.
