Abstract
BACKGROUND: Dolutegravir (DTG), combined with a backbone of two NRTIs, is currently the preferred first-line treatment for HIV in childhood. CHAPAS4 is an ongoing randomized controlled trial (#ISRCTN22964075) investigating second-line treatment options for children with HIV. We did a nested PK substudy within CHAPAS4 to evaluate the DTG exposure in children with HIV taking DTG with food, as part of their second-line treatment. METHODS: Additional consent was required for children on DTG enrolled in the CHAPAS4-trial to participate in this PK substudy. Children weighing 14-19.9 kg took 25 mg DTG as dispersible tablets (DT) and children ≥20 kg took 50 mg film-coated tablets (FCT). Steady-state 24 h DTG plasma concentration-time PK profiling was done at t = 0 and 1, 2, 4, 6, 8, 12, and 24 h after observed DTG intake with food. Reference adult PK data and paediatric data from the ODYSSEY-trial was used primarily for comparison. The individual target trough concentration (Ctrough) was defined as 0.32 mg/L. RESULTS: 39 children on DTG were included in this PK substudy. The Geometric Mean (GM), (CV%) AUC0-24h was 57.1 h*mg/L (38.4%) which was approximately 8% below the average AUC0-24h in children in the ODYSSEY-trial with comparable dosages, but above the adult reference. The GM (CV%) Ctrough was 0.82 mg/L (63.8%) which was comparable to ODYSSEY and adult reference values. CONCLUSIONS: This nested PK substudy shows that the exposure of DTG taken with food in children on second-line treatment is comparable with that of children in the ODYSSEY-trial and adult references.
