A Study to Evaluate Bioavailability and Food Effect of Selumetinib (AZD6244) in Healthy Male Participants

Study Overview
=================
Brief Summary
-----------------
This study will evaluate bioavailability and food effect of selumetinib (AZD6244) in healthy male participants. A total of 24 healthy male participants will be included to ensure at least 20 evaluable participants. The study is divided in 2 study parts; the same participants will participate in both parts of the study. Part 1 of the study is to investigate the pharmacokinetics (PK) of the selumetinib granule compared to the PK of selumetinib capsule, when administered with water under the fasted conditions. Part 2 of the study is to investigate the PK of selumetinib granule and capsule under fed conditions. Participants will also receive a single 500 mg dose of acetaminophen at the same time as selumetinib administration.

Detailed Description
-----------------
This study will be a 2-part, open-label, single-center relative bioavailability and food effect randomized crossover study of new granule and capsule formulations of selumetinib. A total of 24 healthy male participants aged between 18 to 45 years (inclusive), will be included to ensure at least 20 evaluable participants. The study is divided in 2 study parts; the same participants will participate in both parts of the study. Part 1 of the study is designed to investigate the PK of the selumetinib granule compared to the PK of selumetinib capsule, when administered with water under the fasted conditions. Part 2 of the study is designed to investigate the PK of selumetinib granule and capsule under fed conditions. Participants will consume a low-fat, low-calorie meal. Thirty minutes after the start of the meal, selumetinib will be administered to the participants. In all treatment periods, participants will also receive a single 500 mg dose of acetaminophen at the same time as selumetinib administration where it will act as a marker for gastric emptying. The study will also assess the palatability of the selumetinib granule in both parts of the study. Each participant will receive the following treatments: Treatment A: 25 mg granule, fasted state Treatment B: 50 mg capsule, fasted state Treatment C: 25 mg granule, fed state Treatment D: 50 mg capsule, fed state Participant will be randomly assigned to 1 of 4 treatment sequences. In all cases the treatments in Part 1 will be administered before the treatments in Part 2. The study will comprise of a screening period of maximum 28 days. Four treatment periods during which participants will be resident from the day before dosing (Day -1) until at least 48 hours after dosing; discharged on the morning of Day 3. A follow-up visit, will be within 7 to 10 days after the last dose of investigational medicinal product (IMP). There will be a minimum washout period of at least 5 days between each IMP administration. Each participant will be involved in the study for approximately 8 to 9 weeks.
