Time frame
pre-dose, 2, 4, 6, 8 and 10 hours on Cycle 1 Day 15 (Crizotinib alone) and Cycle 2 Day 1 (Crizotinib with Rifampin)

Analysis population: PK parameter population was defined as all participants in the Rifampin interaction cohort safety population who satisfied following criteria for Cycle 1 Day 15 or Cycle 2 Day 1: a) had at least 1 of the primary PK parameters of Crizotinib (AUCtau and Cmax). b) Received adequate dosing prior to PK sampling. Here, "Overall number of participants analyzed" signifies number of participants evaluable for this outcome measure.

Groups in this outcome

RP2D Cohort: Rifampin Interaction: Crizotinib 250 mg Alone

Participants received Crizotinib 250 mg (2 capsules/tablet of 100 mg each + 1 capsule/tablet of 50 mg) capsule/tablet twice daily (BID) with or without food from Cycle 1 Day 1 up to 13 cycles (each cycle 28 days).

RP2D Cohort: Rifampin Interaction: Crizotinib 250 mg With Rifampin

Participants received Crizotinib 250 mg (2 capsules/tablet of 100 mg each + 1 capsule/tablet of 50 mg) capsule/tablet twice daily (BID) form Cycle 1Day 1 up to 13 cycles (each cycle 28 days). Participants also received commercially available Rifampin 650 mg QD from Cycle 1 Day 16 to Cycle 2 Day 1 (14 days) either one hour before or 2 hours after a meal.
