Evaluating the Effects of Omeprazole on the Pharmacokinetics of XS004 (Dasatinib) Tablets in Healthy Adult Subjects Under Fasting Conditions

An Open Label, Non-Randomized, Two-Treatment, Single-Period, Single-Dose, Drug-Drug Interaction Study to Evaluate the Effects of Omeprazole on the Pharmacokinetics of XS004 (Dasatinib) 90 mg Film-Coated Tablets in Healthy Adult Subjects Under Fasting Conditions

In this open label, single-sequence study, subjects received one dose of XS004 Dasatinib Amorphous Solid Dispersion Film-Coated Tablet, 90 mg Test Formulation at the start of study on Day 1 and Day 6. Omeprazole 40 mg was administered on Day 2, 3, 4, 5 and 6. The study was conducted in two groups.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Dasatinib ASD alone; At the clinic, participants were administered a single oral dose of 90 mg Dasatinib (Amorphous Solid Dispersion Film-Coated Tablet) on Day 1 after an overnight fast of at least 9 hours. Dasatinib was given with approximately 240 mL of room temperature water. Fasting continued for at least 4 hours following drug administration, after which a standardized lunch was served.	Drug: Dasatinib ASD; XS004 Dasatinib Amorphous Solid Dispersion Film-Coated Tablet, 90 mg Test Formulation
Other: Dasatinib ASD + Omeprazole; At the clinic, on Day 2 to Day 6, participants were administered a single oral dose of Omeprazole 40 mg × 1 Delayed Release Capsule once before meals in the evening with approximately 150 mL of room temperature water. No food was allowed two hours before and one hour after administration of Omeprazole. In addition, participants were administered a single oral dose of 90 mg Dasatinib (Amorphous Solid Dispersion Film-Coated Tablet) on Day 6 after an overnight fast of at least 9 hours. Dasatinib was given with approximately 240 mL of room temperature water. Fasting continued for at least 4 hours following drug administration, after which a standardized lunch was served.	Drug: Dasatinib ASD; XS004 Dasatinib Amorphous Solid Dispersion Film-Coated Tablet, 90 mg Test Formulation; Drug: Omeprazole 40 MG; Omeprazole Delayed Release Capsules, USP 40 mg

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Observed Plasma Concentration of Dasatinib (Cmax)	Pharmacokinetic parameters (Cmax) for plasma dasatinib on Day 1 (Dasatinib alone) and on Day 6 (Dasatinib + Omeprazole) calculated for each subject using drug concentration-time data by non-compartmental methods.	Blood samples collected at 15 time points (including pre-dose) during the study period on Day 1 and Day 6.
Area Under the Plasma Concentration-Time Curve from Zero to 24h	Pharmacokinetic parameters (AUC 0-24) for plasma dasatinib on Day 1 (Dasatinib alone) and on Day 6 (Dasatinib + Omeprazole) calculated for each subject using drug concentration-time data by non-compartmental methods.	Blood samples collected at 15 time points (including pre-dose) during the study period on Day 1 and Day 6.
Area Under the Plasma Concentration-Time Curve from Zero Extrapolated to Infinity	Pharmacokinetic parameters (AUC 0-INF) for plasma dasatinib on Day 1 (Dasatinib alone) and on Day 6 (Dasatinib + Omeprazole) calculated for each subject using drug concentration-time data by non-compartmental methods.	Blood samples collected at 15 time points (including pre-dose) during the study period on Day 1 and Day 6.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Plasma Concentration-Time Curve (Percent Extrapolation)	Pharmacokinetic parameters (AUC %Extrapolation) for plasma dasatinib on Day 1 (Dasatinib alone) and on Day 6 (Dasatinib + Omeprazole) calculated for each subject using drug concentration-time data by non-compartmental methods.
