Time frame
Pre-dose and 1, 2, 3, 4, 6, 8, 10-12 and 18-24 hours after selumetinib single dose on the first day of study treatment (Cycle 1 Day 1). Pre-dose, 1, 2, 3, 4, 6, 8, and 10-12 hours post-dose on Cycle 2 Day 1 (each cycle is 28 days)

What was measured

To further evaluate the PK of the granule formulation.

Analysis population: Pharmacokinetic analysis set was used for analysis. Some records were excluded for given visits and analytes due to missing concentration data, issues taking the medication and usage of prohibited medications.
