A randomised non-inferiority trial with nested PK to assess DTG/3TC fixed dose formulations for the maintenance of virological suppression in children with HIV infection aged 2 to <15 years old

Is a new tablet that contains two medicines together, dolutegravir (DTG) and lamivudine (3TC), as good as the HIV medicines that children and young people currently take?

What is this study about?

This study aims to find out whether treating children and young people living with HIV with two anti-HIV medicines, dolutegravir (DTG) and lamivudine (3TC), is safe and as effective as dolutegravir-based treatment with three anti-HIV medicines.
