Group Intervention Description TQ-A3326 TQ-A3326 TQ-A3326 (15mg-180mg: p.o. single dose; 60mg: p.o. multi-doses） placebo placebo Placebo(15-180mg: p.o. single dose; 60mg: p.o. multi-doses)
- Primary Outcome Measures
Name Time Method Number of Participants With Serious Adverse Events (SAEs). Day 1 up to Day 7 for non-SAEs . SAEs were defined as any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgement of investigators represent significant hazards.
Number of Participants With Clinically Significant Change From Baseline in Vital Sign Measurements. Day 1 up to Day 7 or Discharge. Participants were assessed by investigator for any clinically significant changes in vital parameters like body temperature, respiratory rate, blood pressure, heart rate and weight. The assessment was performed by a calibrated sphygmomanometer and thermometer for blood pressure and temperature, respectively. Blood pressure and heart rate were measured after at least 5 minutes quiet seating of the subject. Weight was measured at the discharge. The criteria for clinically significant change was as per the investigators discretion.
Number of Participants With Marked Abnormalities in Laboratory Findings. Day 1 up to Day 7. Laboratory marked abnormalities were defined as Hematocrit (low) as \<0.85\*pre-treatment value, Leukocytes (low) as \<0.9\*lower limit of normal, Aspartate Aminotransferase (high) as \>1.25\*upper limit of normal, Creatinine (high) as \>1.33\*pre-treatment value, Bicarbonate (high) as \>1.2\*upper limit of normal, Total Protein (high) as \>1.1\*upper limit of normal, Creatinine Kinase (high) as \>1.5\*upper limit of normal, Blood in Urine (high) as ≥ 2\*upper limit of normal. Participants were fasted for at least 10 hours prior to the collection of blood specimens for clinical laboratory tests.
- Secondary Outcome Measures
Name Time Method Time to Reach Maximum Plasma Concentration (Tmax). Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1. Tmax was defined as the time required to reach maximum observed plasma concentration. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
Maximum Observed Plasma Concentration (Cmax). Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1 Maximum observed plasma concentration following drug administration from the raw plasma concentration-time data. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
2）Grade 4 hematology toxicityArea Under the Plasma Concentration-time Curve From Time Zero to the Time of Last Quantifiable Concentration (AUC[0-T]). Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1. Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration. It was calculated as the sum of linear trapezoids using non-compartmental analysis. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
Area Under the Plasma Concentration-time Curve From Time Zero (AUC[INF]) Extrapolated to Infinite Time. Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1. Area under the plasma concentration-time curve from time zero extrapolated to infinite time was estimated as sum of AUC(0-T) and the extrapolated area, computed by the quotient of the last observable concentration and λ, where λ was the slopes of the terminal phases of the plasma concentration-time profiles. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
Plasma Half-life (T-half) Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1. Plasma half-life was defined as the time required for one half of the total amount of administered drug eliminated from the body. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
Apparent Total Body Clearance (CLT/F) Pre-dose, 0.25hour, 0.5hour, 1hour, 1.5hour, 2hour, 3hour, 4hour, 6hour, 8hour, 12hour, 24hour, 48hour, 72hour, 96hour, 120hour post-dosing on Day 1. Apparent total body clearance (CLT/F) was calculated as Dose/AUC(INF), where CLT was the clearance of the drug and F was the absolute oral bioavailability. The plasma samples were analyzed for TQ-A3326 using a validated liquid chromatography-tandem mass spectrometric assay.
