About The Study

The objective of this international, multicenter, prospective observational comparative study is to monitor the safety of long term use of maraviroc in a larger and more diverse patient population than that in which the Phase 2b/3 clinical trials were conducted. By providing additional data regarding long-term use of maraviroc, this study will help further characterize the safety profile of the drug.
