Study arms

  • Experimental
    Single Ascending Dose Study

    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

  • Experimental
    Multiple Ascending Dose Study

    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

  • Experimental
    Food Effect Study

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

    Other: Food Effect

Interventions

  • DrugSingle ascending dose of X842

    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

  • DrugMultiple ascending dose of X842

    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

  • OtherFood Effect

    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.

What researchers measure

Primary outcomes

  1. Occurrence and frequency of AEs after single and multiple doses of X842.

    Safety and tolerability will be assessed by occurrence and frequency of AEs. The adverse event assessment will follow the recommendations and grading system of Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Summary statistics will be applied.

    Time frame: Five Weeks

  2. Vital signs of body temperature

    Time frame: Five Weeks

  3. Vital signs of blood pressure

    Blood pressure measurements included systolic (mmHg) and diastolic (mmHg).

    Time frame: Five Weeks

  4. Vital signs of respiratory rate

    Time frame: Five Weeks

  5. Physical Examination of height

    Time frame: Five Weeks

  6. Physical Examination of weight

    Time frame: Five Weeks

  7. Number of clinically significant changes in Electrocardiograms (ECGs)

    The investigator or the sub-investigator interpreted the ECG using one of the following categories: "within normal limits", "abnormal but not clinically significant", or "abnormal and clinically significant".

    Time frame: Five Weeks

  8. Number of Clinically significant changes in lab assessment of blood serum

    Time frame: Five Weeks

  9. Number of Clinically significant changes in the lab assessment of blood

    Time frame: Five Weeks

  10. Number of Clinically significant changes in the lab assessment of urine

    Time frame: Five Weeks

Secondary outcomes

  1. Measurement of the PK profile (Cmax)

    To assess the Maximum Plasma Concentration (Cmax)

    Time frame: Up to 48 hours after dosing

  2. Measurement of the PK profile (t1/2)

    To assess the plasma half life (t1/2) of drug

    Time frame: Up to 48 hours after dosing

  3. Measurement of the PD profile (intragastric pH)

    To assess and characterize the PD profile with measurements of intragastric pH

    Time frame: Up to 24 hours after dosing
