This study consists of two parts: Part A and Part B. Part A is a single-center, randomized, open-label, three-period study intended to evaluate the effects of low-fat and high-fat meals on the pharmacokinetic profiles of ABSK-011 Capsules. A total of 15 healthy participants are planned to be enrolled. Participants will be randomized to Sequence A, Sequence B or Sequence C at a 1:1:1 ratio and receive a single oral dose of ABSK-011 (50 mg × 4) on three separate occasions with a 4-day washout interval between administrations. 39 PK blood sampling time points will be collected in Part A.
Part B is a single-center, open-label, fixed-sequence study designed to assess the impact of multiple oral doses of omeprazole enteric-coated tablets on the pharmacokinetic profiles of ABSK-011 Capsules. 15 healthy participants are planned for enrollment. On Day 1 of Cycle 1 (C1D1), participants will receive 200 mg ABSK-011 Capsules in the morning after a low-fat meal. From Day 1 to Day 5 of Cycle 2 (C2D1-C2D5), participants will take 40 mg omeprazole enteric-coated tablets orally once daily under fasted conditions. 26 PK blood sampling time points will be collected in Part B.
