All trials for HIV-1-infection All trials for Pregnancy Related All trials of Dolutegravir All trials of Standard of Care (EFV + 2 NRTI backbone)
To evaluate dolutegravir (DTG) efficacy in women who present with untreated HIV in late pregnancy.
An open-label, multi-centre randomised controlled trial of DTG vs efavirenz-based regimens for women commencing cART in late pregnancy. HIV positive pregnant women presenting with untreated HIV infection in late (≥28 weeks gestation) pregnancy will be randomised 1:1 to receive DTG (50mg once daily) + 2 nucleoside reverse transcriptase inhibitors (NRTIs) or EFV + 2 NRTIs (SoC)
This is an open-label, randomised controlled trial of DTG versus EFV -based regimens for 250 women commencing cART in late pregnancy, randomised 1:1 to DTG vs EFV-based cART. The purpose of this study is to inform treatment guidelines and for the first time specifically address the treatment needs of this group of women- hence the trial is powered for superiority over EFV. The primary endpoints is maternal VL at delivery, with secondary endpoints including safety and tolerability of DTG in both mother and infant, VL decline in breast milk, development of drug resistance, pharmacokinetics of DTG in mother-infant pairs, pharmacogenomics factors relating to efficacy or toxicity of DTG, and MTCT of HIV up to 72 weeks postpartum. Two sites have been selected - Infectious Diseases Institute, Makerere University, Kampala, Uganda and the University of Cape Town, South Africa - both have a strong track record of successfully delivering collaborative multidisciplinary research in PMTCT. Furthermore, health economics analysis to examine costs and cost-effectiveness of DTG in late-presenting pregnant women will be conducted
The desired outcome of this project is to establish high quality evidence and operational guidance for use of DTG in late pregnancy. Late-presenting HIV-infected pregnant women are an important, but neglected group of vulnerable individuals in whom a randomised controlled intervention of HIV treatment has never previously been undertaken. This work will be done in relationship with WHO and the Clinton Health Access Initiative to ensure successful delivery of the project objectives.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Dolutegravir | Experimental | Drug: Dolutegravir | Dolutegravir group (DTG+2 NRTIs) - to make best comparison with standard of care, these NRTIs should be those recommended by national policy. Participants randomized to the study drug will be commenced on an antiretroviral regimen comprising DTG 50mg once daily in combination with 2 NRTIs |
| Standard of Care (EFV + 2 NRTI backbone) | Active comparator | Drug: Standard of Care (EFV + 2 NRTI backbone) | Participants randomized to receive standard of care will receive the currently used antiretroviral regimens in keeping with national policy (EFV + 2NRTIs at both study sites). |
Sex: Female, ages: 18 Years to any

Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. 3. Women aged 18 years or older 4. Pregnant ( ≥28 weeks gestation by best available gestation estimation) 5. Untreated HIV infection in late pregnancy Exclusion Criteria: 1. Received any antiretroviral drugs in previous 12 months 2. Ever received integrase inhibitors 3. Previous documented failure of an NNRTI-containing ART regimen, previous EFV-associated toxicity or other history of ARV use that would preclude randomisation based on investigator judgement 4.
