Bioequivalence Study for Crizotinib Encapsulated Microsphere Formulation (eMS)
Study Details
Study Description
Brief Summary
Bioequivalence study to evaluate the pharmacokinetics of a new crizotinib encapsulated microsphere (eMS) formulation
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
In order to overcome the poor taste/palatability associated with the original oral solution formulation of crizotinib for pediatric patients, an encapsulated microsphere (eMS) formulation with improved palatability compared with the oral solution and acceptable PK characteristics was developed.
The primary objective of this study is to establish the bioequivalence of the eMS formulation to the current commercial formulation, ie, formulated capsule (FC), in adult healthy participants to support the commercialization of this new formulation.

Outcome Measures
Primary Outcome Measures
- Plasma AUCinf after administration of the FC formulation [Day 1, Pre-dose, hour 1, 2,4,6,8,12,24,48,72,96,144 (Periods 1-3)]
Area under the plasma concentration-time profile from time zero extrapolated to infinite time Method of Determination: Linear-log trapezoidal method
- Plasma Cmax after administration of the FC formulation [Day 1, Pre-dose, hour 1, 2,4,6,8,12,24,48,72,96,144 (Periods 1-3)]
Maximum plasma concentration Method of Determination: Observed directly from the data
- Plasma AUClast after administration of the FC formulation [Day 1, Pre-dose, hour 1, 2,4,6,8,12,24,48,72,96,144 (Periods 1-3)]
Area under the plasma concentration time profile from time zero to the time of the last quantifiable concentration (Clast) Method of Determination: AUClast + (Clast/kel) Where Clast is the predicted plasma concentration at the last quantifiable time point and kel is the elimination rate constant estimated from the loglinear regression analysis.
- Plasma AUCinf after administration of the unencapsulated eMS formulation [Day 1, Pre-dose, hour 1, 2,4,6,8,12,24,48,72,96,144 (Periods 1-3)]
Area under the plasma concentration-time profile from time zero extrapolated to infinite time Method of Determination: Linear-log trapezoidal method

Maximum plasma concentration Method of Determination: Observed directly from the data
- Plasma AUClast after administration of the unencapsulated eMS formulation [Day 1, Pre-dose, hour 1,2,4,6,8,12,24,48,72,96,144 (Periods 1-3)]
Area under the plasma concentration time profile from time zero to the time of the last quantifiable concentration (Clast) Method of Determination: AUClast + (Clast/kel) Where Clast is the predicted plasma concentration at the last quantifiable time point and kel is the elimination rate constant estimated from the loglinear regression analysis.
