History of Changes
This study is a Phase 2b, multi-center, extension study designed to evaluate the long-term
efficacy, safety, and tolerability of PRO 140 monotherapy for the maintenance of viral
suppression in patients who were stable on combination antiretroviral therapy and completed
12 weeks of treatment under PRO140_CD01 Treatment Substitution Study without experiencing
Consenting patients will continue to receive PRO 140 monotherapy for 160 additional weeks. Total treatment duration with PRO 140 will be up to 161 weeks with one week overlap of existing retroviral regimen and PRO 140 at the end of the treatment extension phase in subjects who do not experience virologic failure.

Primary Outcome Measures
Time to virologic failure after initiating PRO 140 monotherapy.
[ Time Frame: 160 weeks ]
Virologic failure is defined as two consecutive HIV-1 RNA levels of ≥ 400 copies/ml separated by at least 3 days.
- Proportion of Participants with virologic failure after initiating PRO 140 monotherapy. [ Time Frame: Up to160 weeks ]
- Mean change in viral load (HIV-1 RNA levels) [ Time Frame: Up to 160 weeks ]
- Mean change in CD4 cell count [ Time Frame: Up to 160 weeks ]
- Change in Quality of Life metrics (up to TE107) [ Time Frame: Up to 160 weeks ]
- Tolerability of repeated subcutaneous administration of PRO 140 as assessed by study participants(using Visual Analogue Scale) and by investigator-evaluation of injection site reactions. [ Time Frame: Up to 160 weeks ]
- Frequency of Grade 3 or 4 adverse events as defined by the DAIDS Adverse Event scale [ Time Frame: Up to 160 weeks ]

- Laboratory test values ≥ grade 4 DAIDS laboratory abnormality.
- Females who are pregnant, lactating, or breastfeeding, or who plan to become pregnant during the study
- Unexplained temperature >38.5C (101.3F) for seven consecutive days within 14 days prior to the first study dose
- Diagnosed with either substance dependence or substance abuse or any history of a concomitant condition (e.g., medical, psychologic, or psychiatric) that in the opinion of the primary care provider and/or site investigator would interfere with the subject's successful completion of the study requirements
- Any other clinical condition that, in the Investigator's judgment, would potentially
