Study Arms (3)

Single Ascending Dose Study

EXPERIMENTAL

Healthy subjects will be screened and different doses of X842 will be administered in a single dose to assess the safety, tolerability, PK and PD profile of X842.

Drug: Single ascending dose of X842

Multiple Ascending Dose Study

EXPERIMENTAL

Healthy subjects will be screened and different doses of X842 will be administered in multiple doses to assess the safety, tolerability, PK and PD profile of X842. The dose ascending at this stage will be based on the results of the single dose tolerability study.

Drug: Multiple ascending dose of X842

Food Effect Study

EXPERIMENTAL

A randomized, open label, single-dose, self-controlled, double-cycle, two-way crossover clinical trial.

Other: Food Effect

Interventions

Single ascending dose of X842 DRUG

A total of 7 dose groups will be set for the ascending dose: 5.6 mg, 12.5 mg, 25 mg, 50 mg, 100 mg, 150 mg, 225 mg. In the 5.6 mg dose group, 4 subjects will receive X842; in the 12.5 mg, 25 mg, 50 mg, 100 mg, 150 mg, 225 mg dose groups, 8 subjects in each group will receive X842. Each subject can only receive a certain dose level and cannot enter in multiple dose groups repeatedly.

Also known as: X842

Single Ascending Dose Study

Multiple ascending dose of X842 DRUG

Two dose groups will be set, including the groups receiving the recommended phase II dose and a higher dose; Eight subjects will be enrolled in each group, with half male and half female, who will receive X842 once daily for 5 consecutive days. Each subject can only receive a certain dose level and cannot enter in multiple dose groups repeatedly.

Also known as: X842

Multiple Ascending Dose Study

Food Effect OTHER

Twelve subjects (appropriate ratio of male to female) screened for eligibility will be randomized into Group A and B. The 6 subjects in Group A will take the study drug (X842) in fasted condition and subject in Group B will take the study drug in fed condition in the 1st cycle. In the 2nd Cycle, subjects in Group A will take the study drug in fed condition, and subjects in Group B will take the study drug in fasted condition. The interval between the two cycles is at least 7 days.
