Study Summary

The purpose of this study is to study how changes in the body during pregnancy influence the blood levels of TMC114 (darunavir) and ritonavir taken together, darunavir and cobicistat taken as a fixed-dose combination, TMC125 (etravirine) taken alone or with darunavir and ritonavir or rilpivirine in patients with human immunodeficiency virus-1 (HIV-1). This study will examine how these drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time. Any pregnant woman who is currently receiving darunavir with ritonavir, darunavir with cobicistat, etravirine or rilpivirine for HIV-1, and who meets the eligibility criteria for the study, will be allowed to enroll. Patients must be willing to remain on study medication during the course of their pregnancy, and 12 weeks postpartum. The information collected may help answer questions about how to best prescribe these three drugs for pregnant women.
