Dolutegravir (DTG) and lamivudine (3TC) [dolutegravir (33832), lamivudine (42406)] ...Study Participants
370This study aims to find out whether treating children and young people living with HIV with two anti HIV medicines, dolutegravir and lamivudine, is safe and as effective as the three-medicine anti-HIV treatments currently used in routine practice.
This study will include 370 children and young people aged 2 to less than 15 years old who are living with HIV and are being treated with anti-HIV medicines for the first time. Participants will be split into two groups, by chance, by a process called "randomisation". One group will continue to receive the anti-HIV medicines already taken according to country-specific routine practice. The second group will change to the new combination of medicine, dolutegravir and lamivudine (with the combination written usually as "DTG/3TC"). Depending on the weight, participants in the second group will be able take the new medicine either as one tablet a day or as a small number of dispersible tablets that are also taken once a day. All children and young people in the study will have regular clinic assessments that are at a similar frequency to the clinic visits that participants would have outside of the study. Blood tests will be performed to check that the medicine is safe and, at some visits, participants and their carers will also be asked to answer some questions on how they feel about taking their medicine. All children and young people will be followed until the last participant who joins the study has been in the study for 96 weeks.
Children randomised to the DTG/3TC arm will receive once daily DTG/3TC fixed dose combination dispersible or film-coated tablets dosed using WHO weight bands criteria
