%X <B>OBJECTIVE: </B>Dolutegravir (DTG) has proved to be more efficacious, tolerable, and safer than efavirenz (EFV) among mothers living with HIV and their infants in Uganda. This study assessed the cost-effectiveness of the DTG-based antiretroviral therapy (ART) compared with the standard of care for preventing perinatal transmissions among pregnant women initiating ART in late pregnancy in Uganda.<BR><B>METHODS: </B>We used data from a randomized open-label trial (DolPHIN-2) and a 2-part cost-effectiveness model composed of a short-term decision tree to estimate the perinatal transmission rate and costs and an individual-based 3-state Markov model (HIV, advanced HIV, dead) to estimate the long-term costs and health outcomes from the Ugandan payer perspective using a lifetime horizon and a 1-year Markov cycle. The main outcomes were the mean annual costs in US dollars ($), disability-adjusted life-years (DALYs), and incremental cost-effectiveness ratio. Both the deterministic and probabilistic sensitivity analyses were conducted to assess the effect of parameter uncertainties on the ultimate results and the model's robustness.<BR><B>RESULTS: </B>Compared with the EFV-based ART, the DTG-based ART was associated with fewer mean annual costs ($43.58 vs $68.44) and DALYs (0.33 vs 0.56), leading to cost savings of $110 per DALY averted. In the incremental analysis, the DTG-based ART dominated the EFV-based ART; that is, it was less costly and more effective. These results were robust to deterministic and probabilistic sensitivity analyses.<BR><B>CONCLUSIONS: </B>The DTG-based ART is a highly cost-effective strategy compared with the EFV-based ART among women initiating treatment in the third trimester of pregnancy in a low-income setting.
