Safety and Pharmacokinetics of Dolutegravir in Pregnant HIV Mothers and Their Neonates: A Pilot Study

CompletedPhase 2, Phase 3

Sponsor: University of Liverpool

Conditions: HIV, Pregnancy

Interventions: Dolutegravir 50mg od, Standard of Care

Countries: South Africa, Uganda

Aim: To evaluate dolutegravir (DTG) pharmacokinetics in pregnant HIV-infected women Rationale: In developing countries many women present with a new HIV diagnosis in late pregnancy, and are at high risk of transmitting infection during delivery. Moreover, women may acquire NNRTI resistance from primary transmission, or use of nevirapine (NVP) in previous pregnancies. In these circumstances, DTG is likely to be more effective in reducing mother to child transmission of HIV than NNRTI-based regimens. Study design: HIV positive pregnant women presenting with untreated HIV infection in late (≥28 -36 weeks gestation) pregnancy will be randomised 1:1 to receive DTG (50mg once daily) or standard of care (nevirapine or efavirenz) + 2 NRTIs. PK (0-24h) profile will be sampled in third trimester and post-partum. Although this is primarily a PK study (and has been powered as such) randomisation is included to allow comparison of plasma HIV VL responses against standard of care (NVP or EFV) and is essential for evaluation of secondary endpoints of safety and efficacy of DTG in pregnancy. Number recruited N=30 per group
