Study Summary

This study is a Phase 2b study designed to evaluate the efficacy, safety, and tolerability of PRO 140 monotherapy for the maintenance of viral suppression in subjects who are stable on combination antiretroviral therapy. Consenting subjects will be shifted from their combination antiretroviral regimen to PRO 140 monotherapy for 12 weeks. Total treatment duration with PRO 140 will be 14 weeks with the one week overlap of existing retroviral regimen and PRO 140 at the beginning of the study treatment, and one week overlap at the end of the treatment in subjects who do not experience virologic failure.

Primary Outcome

Time to virologic failure after initiating PRO 140 monotherapy. Virologic failure was defined as two (2) consecutive HIV-1 RNA levels of ≥ 400 copies/mL.
