Effect of Food on Bioavailability of Modified Release Formulations of Imatinib

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the effect of food on the relative bioavailability of a single dose of imatinib given as a 800 mg modified release tablet, compared to twice-daily doses of 400 mg film-coated tablets. There will be a 8 day wash out phase between treatments and a 1 week safety period at the end of the study. Each participant will receive all four treatments.

Official Title
-----------------
A Phase I, Two Arm, Open-label, Randomized, Study to Investigate the Effect of Food on the Bioavailability of a Single 800 mg Imatinib Dose in Modified Release Formulations (MR3 and MR4) and Compare the Bioavailability Between MR3, MR4 and Imatinib 400 mg Twice Daily Immediate Release Tablet (IR) in Healthy Subjects

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To compare the bioavailability of Modified Release formulations to 400 mg immediate release (IR) tablet when administered twice-daily (both given with a low fat meal). |  |  | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To compare the relative bioavailability of a single daily 800 mg dose of modified release formulations with a high fat meal and a low fat (regular) meal, to modified release formulations after over-night fasting in healthy volunteers. |  |  | 
| To compare safety and tolerability of the 800 mg daily dose modified release formulations with or without food |  |  |
