结局指标
主要结局
Objective Response Rate (ORR) - Percentage of Participants With Objective Response
时间窗: Baseline up to disease progression, death, or withdrawal; performed at baseline and repeated every 8 weeks for 24 weeks, then every 12 weeks.
ORR was defined as the proportion of participants with objective response based assessment of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR was defined as complete disappearance of all target lesions and non-target disease. No new lesions. PR was defined as \>=30% decrease on study under baseline of the sum of longest diameters of all target lesions. No unequivocal progression of non-target disease. No new lesions.
次要结局
- Progression-Free Survival (PFS)(Baseline up to disease progression, death, or withdrawal; performed at baseline and repeated every 8 weeks for 24 weeks, then every 12 weeks.)
- Overall Survival (OS)(Baseline up to disease progression, death, or withdrawal; performed at baseline and repeated every 8 weeks for 24 weeks, then every 12 weeks.)
- Time to Reach Maximum Observed Plasma Concentration (Tmax) for Axitinib,(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Duration of Response (DR)(Baseline up to disease progression, death, or withdrawal; performed at baseline and repeated every 8 weeks for 24 weeks, then every 12 weeks)
- Maximum Observed Plasma Concentration (Cmax) of Axitinib(Cycle 2 Day 15 (C2D15): pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Apparent Oral Clearance (CL/F) of Axitinib(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Change From Baseline in Diastolic Blood Pressure(At screening (D-14 to D-1); lead-in period: Cycle 1 - Day 1 and Day 15; Cycle 2 - Day 1 and Day 15; Cycle 3 & subsequent cycles Day 1; end of study and follow-up 28 days after last dose.)
- Comparison of Circulating Endothelial Cells (CECs) in Blood: Cluster of Differentiation (CD)146+/CD105+ at Baseline(At baseline - Beginning of the lead-in period (Cycle 1 Day 1))
- PFS in Subgroups That Were Defined by Vascular Endothelial Growth Factor A (VEGFA) or Vascular Endothelial Growth Factor Receptor 3 (VEGFR3) Polymorphisms(At baseline - Beginning of the lead-in period (Cycle 1 Day 1))
- Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for Axitinib(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Apparent Volume of Distribution During the Elimination Phase (Vz/F) for Axitinib(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Change From Baseline in Systolic Blood Pressure(At screening (D-14 to D-1); lead-in period: Cycle 1 - Day 1 and Day 15; Cycle 2 - Day 1 and Day 15; Cycle 3 & subsequent cycles Day 1; end of study and follow-up 28 days after last dose.)
- Comparison of the Ratio of CECs in Blood: CD146+/CD105+ at Each Time Point to Baseline(At end of the lead-in period (Cycle 1 Day 15), Cycle 2 Day 15 and End of therapy (EOT))
- Circulating Endothelial Cells (CECs) in Blood: CD31+/CD146+(At baseline - Beginning of the lead-in period (Cycle 1 Day 1))
- Comparison of Ratio of CECs in Blood: CD31+/CD146+ at Each Time Point to Baseline(At end of the lead-in period (Cycle 1 Day 15), Cycle 2 Day 15 and End of therapy (EOT))
- Area Under the Curve From Time Zero to 24 Hours[AUC(0-24)] for Axitinib(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- Plasma Decay Half-Life (t1/2) for Axitinib(C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose)
- ORR in Subgroups That Were Defined by Vascular Endothelial Growth Factor A (VEGFA) or Vascular Endothelial Growth Factor Receptor 3 (VEGFR3) Polymorphisms(At baseline - Beginning of the lead-in period (Cycle 1 Day 1))
