ODYSSEY (PENTA20)

A randomised trial of dolutegravir-based antiretroviral therapy vs. standard of care in children with HIV infection starting first-line or switching to second-line antiretroviral therapy.

Is a new combination of anti-HIV medicines including dolutegravir as good as current standard HIV treatment in children?

What is this study about?

Dolutegravir is a new drug that offers the potential to be highly effective, safe and simple when used as part of first- or second-line antiretroviral regimens. Following adult Phase II/III trials, dolutegravir needs evaluation to determine its place as first-line and second-line therapy in treating children with HIV.

DTG has high potency at a low milligram dose. This means it could be particularly attractive for young children, who have limited options and may be more likely to be infected with resistant viruses through mother-to-child transmission (MTCT). A DTG-based first-line regimen is likely to be better tolerated and have logistical advantages for ART programmes currently using liquid LPV/r (recommended for young children). DTG can be used as part of a second-line regimen in children failing first-line PI-based therapy; despite the presence of viral rebound for long periods, the NRTI backbone remains relatively protected in the presence of a boosted PI

ODYSSEY is a pragmatic strategy trial evaluating the efficacy and safety of dolutegravir-based antiretroviral therapy compared with standard of care in children starting first- or second-line antiretroviral therapy in resource-limited and well-resourced settings.

The primary objective of the study is to assess the difference in virological or clinical failure by 96 weeks between children receiving a DTG-based regimen and those on standard of care.
