Primary Outcome Measures:
  • Number of Participants With Adverse Events [ Time Frame: Up to 795 days of treatment plus 28-days follow-up ]
    Number of participants with any adverse events, adverse events graded as Common Terminology Criteria for Adverse Events Version 3.0 (CTCAE) Grade 3 or higher, serious adverse events, and adverse events resulted in discontinuation.


Secondary Outcome Measures:
  • Maximum Observed Plasma Concentration (Cmax): Single Dose [ Time Frame: Single dose: predose, 0.5, 1, 2, 4, 6, 8, 12, 24, and 32 hours postdose ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax): Single Dose [ Time Frame: Single dose: predose, 0.5, 1, 2, 4, 6, 8, 12, 24, and 32 hours postdose ]
  • Area Under The Plasma Concentration-Time Curve From Time Zero to Time Infinity (AUCinf): Single Dose [ Time Frame: Single dose: predose, 0.5, 1, 2, 4, 6, 8, 12, 24, and 32 hours postdose ]
    AUCinf is obtained from AUC (0 - t) plus AUC (t - infinity).

  • Terminal Phase Plasma Half-Life (t1/2): Single Dose [ Time Frame: Single dose: predose, 0.5, 1, 2, 4, 6, 8, 12, 24, and 32 hours postdose ]
    t1/2 is the time measured for the plasma concentration to decrease by one half.

  • Maximum Observed Plasma Concentration (Cmax): Multiple Dose [ Time Frame: Multiple dose Cycle 1 Day 1 and 15: predose, 0.5, 1, 2, 4, 8 and 12 hours postdose ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax): Multiple Dose [ Time Frame: Multiple dose Cycle 1 Day 1 and 15: predose, 0.5, 1, 2, 4, 8 and 12 hours postdose ]
  • Area Under The Plasma Concentration-Time Curve Over Dosing Interval Tau (AUCtau): Multiple Dose [ Time Frame: Multiple dose Cycle 1 Day 1 and 15: predose, 0.5, 1, 2, 4, 8 and 12 hours postdose ]
    Dosing Interval was 12 hours in this study.

  • Accumulation Ratio for Cmax (Rac Cmax) and Accumulation Ratio for AUCtau (Rac AUCtau): Multiple Dose [ Time Frame: Multiple dose Cycle 1 Day 1 and 15: predose, 0.5, 1, 2, 4, 8 and 12 hours postdose ]
    Rac Cmax is obtained from Cmax (Cycle 1, Day 15) divided by Cmax (Cycle 1, Day 1) Rac AUCtau is obtained from AUCtau (Cycle 1, Day 15) divided by AUCtau (Cycle 1, Day 1)

  • Percent Change From Baseline in Soluble Vascular Endothelial Growth Factor Receptor 2 and 3 (s-VEGFR2 and s-VEGFR3), Vascular Endothelial Growth Factor (VEGF), Soluble Stem Cell Factor Receptor (s-KIT) [ Time Frame: Prior to the initial dose (baseline), Day 1 of Cycle 2 and at the discontinuation ]
    Percent change from baseline is obtained from (observed value minus baseline value) divided by baseline value multiplied by 100 in each parameter, i.e., VEGFR2, s-VEGFR3, s-KIT, and VEGF.

  • The Numbers of Participants With Best Overall Response of Complete Response (CR), Partial Response (PR), Stable Disease (SD), and Progression of Disease (PD) According to the Response Evaluation Criteria in Solid Tumors (RECIST Version 1.0) [ Time Frame: Up to 795 days ]
    CR was defined as the disappearance of all target and nontarget lesions and no appearance of new lesions. PR was defined as at least a 30% decrease in the sum of the longest diameters (SLD) of the targeted lesions. CR and PR had to be documented on 2 occasions separated by at least 4 weeks. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify as PD being demonstrated during the first 8 weeks. PD was defined as at least a 20% increase in the SLD of target lesions compared to the smallest SLD since the study treatment started.
