A Study to Evaluate the Relative Bioavailability of Two Different Pimicotinib Capsules in Healthy Subjects

Phase 1

Completed

• Conditions: Pharmacokinetics
• Interventions: Drug: pimicotinib capsules

• Registration Number: NCT06694948
• Lead Sponsor: Abbisko Therapeutics Co, Ltd

Brief Summary

This is a study to evaluate the relative bioavailability and tolerability of two different pimicotinib capsules in healthy subjects under fasting condition. 26 healthy subjects are planned to be enrolled and will be evenly randomized to either Study Sequence A or Study Sequence B . Subjects in Sequence A/Sequence B will receive a single 50 mg oral dose of test/reference pimicotinib in period 1 and cross over in period 2. Blood samples will be collected for PK analysis in totally 32 time-points.

Arm && Interventions

Group	Intervention	Description
pimicotinib (reference capsule-test capsule)	pimicotinib capsules	subjects in sequence B will receive a single oral dose of 50 mg reference capsule administered as 2 x 25 mg (the capsule was used in phase 3 study Part 1) in period 1 day 1 and receive a single oral dose of 50 mg test capsule administered as 2 x 25 mg (the capsule is commercial formulation to be marketed) in period 2 day 1 .
pimicotinib (test capsule-reference capsule)	pimicotinib capsules	subjects in sequence A will receive a single oral dose of 50 mg test capsule administered as 2 x 25 mg (the capsule is commercial formulation to be marketed) in period 1 day 1 and receive a single oral dose of 50 mg reference capsule administered as 2 x 25 mg (the capsule was used in phase 3 study Part 1) in period 2 day 1.
