Day 1: pre-dose, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, and 24 hours post dose. Day 21: pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 10 hours post-dose

What was measured

The maximum concentration (Cmax) of dabrafenib metabolites hydroxy-dabrafenib (GSK2285403), carboxy-dabrafenib (GSK2298683) and desmethyl-dabrafenib (GSK2167542) after single and repeat doses of DAB alone and in combination with trametinib was measured at Day 1 and Day 21.

Analysis population: PK Population. Only participants who were available at the indicated timepoints were analyzed.

Groups in this outcome

Part D: Dabrafenib (DAB) 75 mg to DAB 75 mg + Trametinib 2 mg

Part D: Dabrafenib 150 mg to DAB 150 mg + Trametinib 2 mg

Participants received dabrefinib 150 mg HPMC capsules BID. These participants, after completion of serial PK collection in the first treatment period, were allowed to continue with dabrafenib 150 mg BID and trametinib 2 mg tablets QD as combination dosing starting on Day 29.

Part D: Dabrafenib 75 mg + Trametinib 2 mg

Participants received dabrefinib 75 mg HPMC capsules BID and trametinib 2 mg tablets QD.

Part D: Dabrafenib 150 mg + Trametinib 2 mg
