Summary

Background:Historically, HIV infection was associated with significant weight loss. However, weight gain is now commonly observed after initiating antiretroviral therapy (ART), particularly in individuals underweight at baseline. It remains unclear whether this weight gain reflects a "return to health" or results from drug-related or metabolic effects, and whether it persists beyond immune restoration. Recent evidence indicates that ART regimens containing second-generation integrase strand transfer inhibitors (INSTIs), such as bictegravir combined with tenofovir alafenamide, are associated with greater weight gain compared to other antiretroviral combinations, raising concerns about potential long-term metabolic consequences.Objective:To evaluate the effectiveness, safety, and tolerability of Doravirine/Lamivudine/Tenofovir Disoproxil Fumarate (DOR/3TC/TDF) compared with Bictegravir/Emtricitabine/Tenofovir Alafenamide (BIC/FTC/TAF) in ART-naïve people living with HIV (PWH) who are overweight or obese.Materials and Methods:This open-label, randomized clinical trial, approved by the Ethics and Scientific Research Committee (No. 3502), will be conducted at the Infectious Diseases Hospital of the National Medical Center "La Raza" from May 2025 to May 2027. ART-naïve PWH, recently diagnosed, with no prior use of pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP), who do not require hospitalization, and have a body mass index (BMI) ≥25 kg/m² and body fat \>20%, will be invited to participate. Participants will provide written informed consent and be randomized 1:1 to receive either DOR/3TC/TDF or BIC/FTC/TAF.
