Bioequivalence And Food Effect Study Comparing The Commercial Formulation Of Crizotinib To Its Clinical Study Formulations And Commercial Formulation With Or Without Food In Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to demonstrate bioequivalence of the Commercial Image Capsule (CIC) relative to the Immediate Release Tablet (IRT) of crizotinib, bioequivalence of CIC relative to Powder in Capsule (PIC) of crizotinib, and lack of an effect of high fat meal on the pharmacokinetics (PK) of crizotinib when administered as CIC Formulation in healthy volunteers.

Detailed Description
-----------------
The purpose of this study is to demonstrate bioequivalence of the CIC relative to IRT and CIC relative to PIC, and lack of an effect of food on the PK of crizotinib in healthy volunteers.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 1<br>All subjects will receive four treatments in one of the indicated orders: A-B-C-D, B-D-A-C, C-A-D-B, D-C-B-A | Drug: crizotinib<br>* Treatment A (Reference 1): a 250 mg single dose of crizotinib administered in a fasted state as 1 × 50-mg IRT and 2 × 100-mg IRTs. Treatment B (Reference 2): a 250 mg single dose of crizotinib administered in a fasted state as 1 × 50-mg PIC and 2 × 100 mg PICs. Treatment C (Test for BE, Reference for Food Effect): a 250 mg single dose of crizotinib administered in a fasted state as 1 × 250-mg CIC.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC [0 - ∞]) | AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞). | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hours (hrs) post crizotinib dose | 
| Maximum Observed Plasma Concentration (Cmax) |  | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) | Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast). | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose | 
| Time to Reach Maximum Observed Plasma Concentration (Tmax) |  | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose | 
| Plasma Decay Half Life (t1/2) | Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose | 
| Apparent Oral Clearance (CL/F) | Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the body. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose | 
| Apparent Volume of Distribution (Vz/F) | Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed. | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose |

| Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC [0 - ∞]) for Crizotinib Metabolite (PF-06260182) | AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞). | 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose |
