Clinical Trial Summary

In this study, the dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) fixed dose combination (FDC) tablet is being made available to women who become pregnant while participating in study ING117172. Continuation of antiretroviral therapy (ART) is key to both mother and the unborn fetus in order to maintain virologic suppression in the mother (thereby decreasing the risk for maternal disease progression), but also to reduce the risk of maternal-fetal transmission of human immunodeficiency virus type 1 (HIV-1) to her unborn child. This study also offers the first opportunity to investigate the impact of pregnancy on DTG pharmacokinetics (PK). This is an open-label, single arm interventional study. The number of women that will be enrolled into this study cannot be established a priori, as unintended pregnancies cannot be determined in advance. The maximum number of women would include all of those women randomized to DTG/ABC/3TC FDC (approximately 237), though unintended pregnancies in all of these women would not be anticipated.
