Study Summary

This study is a Phase 2b/3 multi-center extension study designed to evaluate the long term antiviral activity, safety, and tolerability of the strategy of continuing PRO 140 350mg, 525mg, or 700mg SC (subcutaneous) monotherapy to maintain viral suppression after initial 48 weeks in virologically suppressed subjects. Consenting subjects will continue weekly PRO 140 350mg, 525mg, or 700mg monotherapy during the Treatment Extension Phase with the one-week overlap of existing retroviral regimen and PRO 140 350mg, 525mg, or 700 mg at the end of the treatment in subjects who do not experience virologic failure.
