- •Subjects are willing and able (in the opinion of the investigator) to understand and comply with the procedures and evaluations of the study.
- •Subjects must be willing and legally able to give written informed consent.
排除标准
- •Hepatic or renal disease; any other disease, which may influence the clinical trial results or may lead to health worsening during the trial (according to the investigator's opinion);
- •Clinically significant laboratory abnormalities;

Cohort 1: 8 subjects will be randomized in a 3:1 ratio to be treated either with 10mg XC8 (6 subjects) or placebo (2 subjects, see placebo arm)
干预措施: XC8 (histamine glutarimide) (Drug)
XC8 50mg
Cohort 2: 8 subjects will be randomized in a 3:1 ratio to be treated either with 50mg XC8 (6 subjects) or placebo (2 subjects, see placebo arm)
干预措施: XC8 (histamine glutarimide) (Drug)
XC8 200mg
Cohort 3: 16 subjects will be randomized in a 3:1 ratio to be treated either with 200mg XC8 (12 subjects) or placebo (4 subjects, see placebo arm)

结局指标
主要结局
Physical examination
时间窗: Day 8
Physical examination results will be listed for following: general appearance, skin, head, eyes, ears, nose, throat, neck (including thyroid), lymph nodes, chest, heart, abdomen (including liver examination), extremities, and nervous system.
12-lead ECG
时间窗: Day 8
12-lead ECG results will be analyzed descriptively
Number of Adverse events per treatment arm
时间窗: Change from pre-dose up to Day 36
Adverse events will be summarized descriptively by treatment arm. Verbatim terms will be mapped to preferred terms and organ systems using the current Medical Dictionary for Regulatory Activities version. For each preferred term, frequency counts and percentages will be calculated by cohort.The nature, severity, seriousness, and relationship to study medication will be summarized for all study subjects
Laboratory data
时间窗: Changes from Day 8 (pre-dose) till Day 15
Laboratory data (hematology, biochemistry and urinalysis) will be summarized by treatment arm. Changes from pre-dose will be presented using shift tables (employing the categories 'normal', 'abnormal, clinically not significant' and 'abnormal, clinically significant') and absolute changes in laboratory values, if appropriate.
Vital signs
时间窗: Changes from pre-dose till Day 36
Vital signs (blood pressure, respiratory rate, pulse, and temperature) results will be analyzed descriptively.
