This study examined the pharmacokinetics (PK), safety, and tolerability of fixed-dose combination abacavir (ABC)/dolutegravir (DTG)/lamivudine (3TC) dispersible and immediate release tablets in children living with HIV less than 12 years of age.~Children were enrolled into one of five ABC/DTG/3TC dosing groups based on their weight. The first 5-7 children within each weight-band underwent intensive PK assessments 5-10 days after starting ABC/DTG/3TC to confirm dose selection. Children remained on their initial dose of ABC/DTG/3TC through Week 4. After Week 4, ABC/DTG/3TC dosing was adjusted based on PK results at the individual or weight-band level, and/or an individual child's growth and weight gain over time.~Follow-up study visits for all participants occurred at Weeks 1, 4, 12, 24, 36, and 48. If participants had a known M184 resistance mutation, they had additional study visits at Weeks 8, 16, and 20. Study visits included physical examination, study drug adherence and tolerability questionnaires, blood collection, and intensive PK sampling. Following the Week 48 study visit, some children were allowed to continue follow-up through up to 144 weeks if alternative post-study drug supply was not yet available.
The purpose of this study was to examine the pharmacokinetics, safety, and tolerability of abacavir/dolutegravir/lamivudine dispersible and immediate release tablets in children living with HIV less than 12 years of age.
