Abstract

BACKGROUND • In 2018, the Tsepamo Study, Botswana reported significant increased risk of NTD in women conceiving on DTG (0.94%) 1 leading to a safety alert • Updated analysis of NTD prevalence (08/2014 – 03/2019)2 • 5 NTDs/1,683 deliveries in women on DTG at conception (0.30%, 95% CI 0.13-0.69 vs 0.10%, 95% CI 0.06-0.17 for non-DTG ART at conception • The Antiretroviral Pregnancy Registry recently reported 1 NTD in 312 periconception DTG exposures (0.3%) 3 • The Dolomite Study was set up in 2017 to address use & safety of DTG in pregnancy and exposed infants in Europe and Canada; conducted within the NEAT-ID network and EPPICC (the European Pregnancy and Paediatric Infections Cohort Collaboration)

Aim: To assess pregnancy and neonatal outcomes following DTG use during pregnancy in real-world European settings • Objectives were to describe: • characteristics of pregnant women receiving DTG-based regimens • frequency of adverse pregnancy and birth outcomes, by earliest timing of DTG exposure

Method: Dolomite-EPPICC involves pooled analyses of prospectively collected individual patient data on DTG-exposed pregnancies from participating studies • Data specification based on a modified HIV Data Exchange Protocol (www.hicdep.org) • Data merger included • All pregnancies with any prenatal DTG exposure • With birth outcomes reported by Feb 2019 • Periconception DTG exposure was defined as initial exposure at ≤6 weeks of estimated gestational age (EGA)

Results: 453 pregnancies in 428 women included (Figure) • Pregnancies reported from six countries • 347 (76.6%) UK and Ireland, 45 (9.9%) Spain, 29 (6.4%) Switzerland, 29 (6.4%) Italy, 3 (0.7%) Romania
