Safety and Efficacy of an Antibody to CCR5 in Individuals With HIV Who Are Not Currently on Antiretroviral Therapy

HIV Infections Clinical Trial

Official title:
A Phase 1, Randomized, Placebo-Controlled, Single-Injection, Dose-Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Ccr5mab004 (Human Monoclonal Igg4 Antibody To Ccr5) in Hiv-1 Seropositive Individuals Who Are Not Receiving Concurrent Antiretroviral Therapy

Clinical Trial Summary

This is a phase 1, randomized, placebo-controlled, dose-escalation study of CCR5mAb004 in HIV-1 seropositive individuals who are not receiving concurrent antiretroviral therapy. Subjects will be randomly assigned to receive a single intravenous (IV) infusion of one of four dose levels of CCR5mAb004 or matching placebo. A minimum of 10 subjects will be randomized to each cohort at a ratio of 4:1 (active:placebo). A minimum of 40 and maximum of 60 subjects will be enrolled. This study will be conducted at up to 10 sites in the United States.

Subjects in each cohort will be followed for 56 days after study agent administration. The safety, tolerability, and immunogenicity of CCR5mAb004 will be evaluated based on physical examination, adverse event (AE) reporting, and clinical laboratory tests. Blood will be collected at specified times for the determination of CCR5mAb004 serum concentrations, HIV-1 RNA levels, and CD4+ and CD8+ cell counts. If CD4+ cell counts are less than 200 during the study period, the subject should be offered standard-of-care per HIV treatment guidelines that may include the initiation of appropriate anti-retroviral therapy (AVR). CCR5mAb004 pharmacokinetic (PK) and pharmacodynamics (PD) will be measured over the 56-day study period. Anti-CCR5mAb004 antibody titers will be assessed prior to dosing on Day 0 and on Day 28 and Day 56.
