Outcome Measures
Primary Outcome Measures
- Abnormalities of vital signs (blood pressure, pulse rate, temperature, and respiration rate) [At Screening，Baseline，Day1，Day 3]
Vital signs safe reference range:systolic blood pressure 84-139 mmHg, diastolic blood pressure 50-89 mmHg, pulse rate 50-100 times per min, temperature 35.9-37.6℃, respiration rate 12-20 times per min
- Abnormalities of physical examination [At Screening，Baseline，Day 3]
Medical examinations performed by physicians include:Skin, mucous membranes, lymph nodes, head, neck, chest, abdomen, spine and limbs, nervous system
- Abnormalities of 12-lead ECG [At Screening，Baseline，Day1，Day 3]
An ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTcF intervals should be used. Changes in T-wave, U-wave morphology and overall ECG interpretation will be documented.
- Abnormalities of clinical laboratory [At Screening，Baseline，Day 3]
The clinical laboratory items includes：Blood routine, blood biochemistry, urine routine, blood clotting function, A function three, C Reactive protein
- Abnormalities of Ophthalmic Examination [At Screening，Baseline，Day 3]
Ophthalmic examinations will be performed to assess ophthalmologic findings, including direct/indirect ophthalmologic examination, slit lamp and fundoscopic examination with retinal photographs (both eyes).Photographs of the retina must be taken.
- Measure time of the maximum observed concentration 【Tmax】 [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure maximum observed concentration【Cmax】 [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure apparent terminal elimination half-life【t1/2】 [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure area under the plasma concentration-time curve from time zero extrapolated to infinity (AUC0-∞) [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure area under the plasma concentration-time curve from the first dose to the last measurable sample collection time t (AUC 0-t) [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure Clearance (CL/F) [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
- Measure apparent volume of distribution (Vz/F) [From 0.5 hour pre-dose to 24 hours post-dose]
To evaluate whether there are differences in the pharmacokinetic characteristics of CB06-036 in healthy subjects in China and the United States
