  Purpose
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.

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment

Primary Outcome Measures:
  • Describe the DTG PK parameters during the third trimester of pregnancy (Weeks 18-26 and Weeks 30-36) and at 8-12 weeks postpartum [ Time Frame: PK samples will be collected at pre-dose, and at 1, 2, 3, 4, 6, 8, 12, and 24 hours post dose at each PK visit ]
    PK parameters include: area under the concentration time curve during the dosing interval (AUC [0-tau]), maximum drug concentration (Cmax), drug concentration at the end of dosing interval (Ctau), apparent clearance (CL/F), steady state volume of distribution (Vss/F), and half life (t1/2). PK samples will be collected at weeks 30-36 of pregnancy and 8-12 weeks post pregnancy.

  • Incidence and severity of adverse events (AEs). [ Time Frame: Up to 3 years ]
    All AEs and serious AEs will be collected from Day 1 through to the Continuation phase regardless of relationship to study participation or any other causality.

  • Incidence and severity of laboratory abnormalities [ Time Frame: Up to 3 years ]
    Laboratory parameters include: hematology, clinical chemistry and urinalysis

  • Absolute values and change over time in laboratory parameters [ Time Frame: Baseline and up to 3 years ]
    Laboratory parameters include: hematology, clinical chemistry and urinalysis. Change will be measured as Baseline value minus values at the indicated time points

  • Number of subjects who discontinue study due to AE [ Time Frame: Up to 3 years ]
  • Number of pregnancies with and without demonstrated congenital [ Time Frame: Up to 3 years ]
    To characterize the safety of DTG/ABC/3TC FDC to the developing fetus.


Secondary Outcome Measures:
  • PK profile (Tmax and C0) during the third trimester of pregnancy (Weeks 18-26 and Weeks 30-36) and at 8-12 weeks postpartum [ Time Frame: PK samples will be collected at pre-dose, and at 1, 2, 3, 4, 6, 8, 12, and 24 hours post dose at each PK visit. ]
    PK parameters include: drug concentration immediately prior to dosing at steady state (C0) and time to Cmax (Tmax).

  • DTG PK parameters during the second trimester of pregnancy (Weeks 18-26). [ Time Frame: PK samples will be collected at pre-dose, and at 1, 2, 3, 4, 6, 8, 12, and 24 hours post dose at each PK visit. ]
    PK parameters include: AUC (0-tau), Cmax, Ctau, C0, Tmax, CL/F, Vss/F and t1/2

  • Unbound DTG concentrations in plasma during the second and third trimesters (Weeks 18-26 and Weeks 30-36) and at 8-12 weeks postpartum [ Time Frame: PK samples will be collected at 3 and 24 hours post dose at the PK visits. ]
    Blood samples will be collected during study visits within Weeks 18-26 and Weeks 30-36 of pregnancy, and at 8-12 Weeks post partum

  • Total DTG concentrations in plasma from cord blood compared to those in maternal [ Time Frame: At delivery and if possible, within 30 minutes of each other ]
    If feasible, a cord and maternal blood sample will also be collected at delivery.

  • Incidence of treatment-emergent genotypic and/or phenotypic resistance in subjects who meet confirmed virologic withdrawal criteria [ Time Frame: Up to 3 years ]
  • Characterization of pregnancy outcomes [ Time Frame: Up to 3 years ]
    Pregnancy outcomes include: Caesarean section, premature rupture of membranes, pre-term labor [prior to Week 37 of pregnancy], pre-term delivery, preeclampsia, eclampsia, hemolysis elevated-liver enzymes-low platelet count, pre-gestational diabetes, gestational diabetes, hypertension, multiple gestation, chromosomal abnormalities, intrauterine infection, and drug-induced hepatitis).

  • Characterization of infant outcomes [ Time Frame: Up to 3 years ]
    Infant outcomes include: infant gestational age, length, weight (including percentiles, small gestational age, adequate gestational age, large gestational age, intrauterine growth restriction), and head circumference, and presence or absence of major congenital abnormalities at birth.

  • Number of subjects with plasma HIV-1 Ribonucleic Acid (RNA) < 50 copies/milliliter (c/mL) over time [ Time Frame: Up to 3 years ]
    A plasma HIV-1 RNA sample will be drawn at each visit, within 24 hours of delivery and on the day of the post-partum PK evaluation

  • Number of subjects with plasma HIV-1 RNA < 400 c/mL over time [ Time Frame: Up to 3 years ]
    A plasma HIV-1 RNA sample will be drawn at each visit, within 24 hours of delivery and on the day of the post-partum PK evaluation

  • Absolute values and changes from Baseline in cluster of differentiation 4 (CD4+) T cell counts over time [ Time Frame: Baseline and up to 3 years ]
    A CD4+ cell count sample will be drawn at each visit, within 24 hours of delivery and on the day of the post-partum PK evaluation

  • Incidence of disease progression (HIV-associated conditions, acquired immunodeficiency syndrome [AIDS] and death). [ Time Frame: Up to 3 years ]
    Assessed at each study visit


Estimated Enrollment: 25
Study Start Date: January 1, 2015
Estimated Study Completion Date: October 29, 2021
Estimated Primary Completion Date: October 1, 2021 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
