Phase 1
Completed
Conditions
Asymptomatic HIV Infection
Interventions
Registration Number
NCT02456558
Lead Sponsor
ApoPharma
Brief Summary

This study will evaluate the safety, tolerability, antiretroviral activity, pharmacokinetics, and pharmacodynamics of an intravenous formulation of deferiprone in HIV-infected subjects.

Detailed Description

This is a double-blind, placebo-controlled, randomized trial in 30 asymptomatic HIV-positive adults. There are two sequential cohorts, in which subjects will receive either one of 2 doses of deferiprone or placebo twice daily.
