About

This study is a single center, open lable and fixed sequence test conducted in healthy subjects to evaluate the pharmacokinetic effects of Itraconazole and Rifampicin on a single dose of ABSK021 Oral administration. It is planned to enroll 32 healthy subjects and assign them to two parallel test groups, Part A (ABSK021 combined with Itraconazole) and Part B (ABSK021 combined with Rifampicin).

Full description

Each study section includes a screening period conducted within 28 days prior to the first administration of the investigational drug, a trial period of 2 cycles, and withdrawal visits on the 21st or 14th day (Part A) or 14th day (Part B) after the last dose of ABSK021. This study will end after all participants complete 2 cycles of the trial period and withdraw from the study visit.

Whether subjects who have completed the first cycle of the study will enter the second cycle of the study will be determined by the researcher based on their physical condition and relevant visit examination results. For the subjects who interrupted or permanently suspended the study due to adverse events or clinically significant laboratory Outlier, the interview rate shall be determined according to the requirements of the research institution or the clinical indication syndrome until the AE is resolved or stabilized, whichever occurs first.
