Description:

The goal of this two-sequence, two-cycle, single and multiple-dose Phase I clinical trial is To evaluate the human bioequivalence of the test preparation and the reference preparation in 28 healthy chinese subjects at a single center.

The main questions it aims to answer are:

• Sectionalization - subjects are divided into two sequences (A/B) equally of 14 subjects each

• Phases - The study is divided into 4 phases, screening, cycle 1, cycle 2 and follow-up observation period. The screening period is from D-7 to D-1, with subjects admitted to the phase I clinical trial ward at D-1. D1 starts the first cycle of the trail until D7 ends; After a 3-day washout period, D11 begins the second cycle of administration until D17 ended. D18~D20 are the follow-up observation period. The total study duration is 27 days.

• Medication - All subjects were administered after meal.

Participants in sequence A will receive oral administration of 50 mg TLL-018 extended-release tablet once on day 1 for the first cycle, and then continue to receive the same dosage once daily for 5 consecutive days from day 3. After a 3-day washout period, they will enter the second cycle and will receive one oral dose of 20 mg TLL-018 immediate-release tablet in the morning of day 11, followed by a second dose of 20 at night 12 hours later, then continued to receive 20 mg TLL-018 twice daily for 5 consecutive days from day 13. Hospital observation for 3 days after taking the medication..

Participants in sequence B will receive 20 mg TLL-018 immediate-release tablet in the first cycle and 50 mg TLL-018 extended-release tablet in the second cycle, with the same medication pattern as those in sequence A.
