- Brief Summary
The purpose of this study is to evaluate the safety and tolerability of X842 after administration of single and multiple doses in healthy subjects
- Detailed Description
This is a single-center, open label, First-In-human (FIH), Phase I clinical study to evaluate the safety, tolerability, pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of single dose and multiple doses of X842 capsules in healthy subjects.
The study comprises a Single Ascending Dose (SAD) part, a Multiple Ascending Dose (MAD) part, and a Food Effect (FE) study.

Group Intervention Description Single Ascending Dose Study Single ascending dose of X842 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. Food Effect Study Food Effect A randomized, open label, single-dose, self-controlled, double-cycle, two-way crossover clinical trial. Multiple Ascending Dose Study Multiple ascending dose of X842 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.
- Primary Outcome Measures
Name Time Method Vital signs of blood pressure Five Weeks Blood pressure measurements included systolic (mmHg) and diastolic (mmHg).
Number of clinically significant changes in Electrocardiograms (ECGs) Five Weeks 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".
Number of Clinically significant changes in lab assessment of blood serum Five Weeks Number of Clinically significant changes in the lab assessment of urine Five Weeks Vital signs of body temperature Five Weeks Occurrence and frequency of AEs after single and multiple doses of X842. Five Weeks 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.
Vital signs of respiratory rate Five Weeks Physical Examination of height Five Weeks Physical Examination of weight Five Weeks Number of Clinically significant changes in the lab assessment of blood Five Weeks
- Secondary Outcome Measures
Name Time Method Measurement of the PK profile (t1/2) Up to 48 hours after dosing To assess the plasma half life (t1/2) of drug
Measurement of the PK profile (Cmax) Up to 48 hours after dosing To assess the Maximum Plasma Concentration (Cmax)
Measurement of the PD profile (intragastric pH) Up to 24 hours after dosing To assess and characterize the PD profile with measurements of intragastric pH
