Authors: Cecilia L. Moore, Anna Turkova , Hilda Mujuru , Adeodata Kekitiinwa, Abbas Lugemwa, Cissy M. Kityo, Linda N. Barlow-Mosha, et al, ODYSSEY trial team Published in: BMC Infectious Diseases   Background: Dolutegravir (DTG)-based antiretroviral therapy (ART) is highly effective and well-tolerated in adults and is rapidly being adopted globally. We describe the design of the ODYSSEY trial which evaluates the efficacy and safety of DTG-based ART compared with standard-of-care in children and adolescents. The ODYSSEY trial includes nested pharmacokinetic (PK) sub-studies which evaluated pragmatic World Health Organization (WHO) weight-band-based […]
