Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) - Percentage of Participants With Objective ResponseBaseline 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.

Secondary Outcome Measures
NameTimeMethod
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.

The time from first dose administration to first documentation of objective tumor progression or to death due to any cause. PFS in each arm was assessed using the Kaplan-Meier method and estimates of the PFS curves from the Kaplan-Meier method were presented.

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.

OS was defined as the time from date of the first dose of the study medication to date of death due to any cause. For participants who did not die, their survival times were to be censored at the last date they were known to be alive.

Time to Reach Maximum Observed Plasma Concentration (Tmax) for Axitinib,C2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose

Tmax for steady-state axitinib was evaluated on Cycle 2 Day 15.

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

DR was defined as the time from the first documentation of objective tumor response (complete response - CR or Partial response - PR) to the first documentation of objective tumor progression or to death due to any cause, whichever occurred first. The median values were estimated based on Kaplan-Meier method. 95% confidence interval was based on the Brookmeyer and Crowley method.

Maximum Observed Plasma Concentration (Cmax) of AxitinibCycle 2 Day 15 (C2D15): pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose

Cmax for steady-state axitinib was evaluated on Cycle 2 Day 15. Results were normalized to axitinib 7 mg dose for active titration arm and axitinib 5 mg dose for placebo titration arm. Results were normalized to axitinib 7 mg dose for active titration arm and axitinib 5 mg dose for placebo titration arm.

Apparent Oral Clearance (CL/F) of AxitinibC2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose

Clearance (CL) of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed (F). Clearance is defined as the volume of blood from which drug can be completely removed per unit of time. CL/F for steady-state axitinib was evaluated on Cycle 2 Day 15.

Change From Baseline in Diastolic Blood PressureAt 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.

Value at respective visit minus value at baseline.

Comparison of Circulating Endothelial Cells (CECs) in Blood: Cluster of Differentiation (CD)146+/CD105+ at BaselineAt baseline - Beginning of the lead-in period (Cycle 1 Day 1)

CECs are noninvasive marker of vascular damage, remodeling, and dysfunction. Samples were collected and following proteins were analyzed: CD146+/CD105+ CECs, CD146+/CD105+ mean fluorescence intensity (MFI) platelet derived growth factor receptor (PDGFR)-beta, CD146+/CD105+ MFI phospho-PDGFR (pPDGFR)-beta, CD146+/CD105+ phospho-Vascular endothelial growth factor receptor (pVEGFR), CD146+/CD105+ MFI VEGFR. The ratio of plasma levels of the biomarkers at the selected time point vs baseline is reported.

PFS in Subgroups That Were Defined by Vascular Endothelial Growth Factor A (VEGFA) or Vascular Endothelial Growth Factor Receptor 3 (VEGFR3) PolymorphismsAt baseline - Beginning of the lead-in period (Cycle 1 Day 1)

PFS, defined as the time from randomization to first documentation of objective tumor progression or to death due to any cause, in subgroups that were defined by VEGFA or VEGFR3 polymorphisms. Estimates of the PFS curves from the Kaplan-Meier method were presented.

Change From Baseline in Systolic Blood PressureAt 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.

Value at respective visit minus value at baseline

Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for AxitinibC2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose

Area under the plasma concentration time-curve from zero to the last measurable concentration (AUClast). AUClast for steady-state axitinib was evaluated on Cycle 2 Day 15. Results were normalized to axitinib 7 mg dose for active titration arm and axitinib 5 mg dose for placebo titration arm.

Apparent Volume of Distribution During the Elimination Phase (Vz/F) for AxitinibC2D15: pre-dose, 0.5, 1, 2, 4, and 6 hours post-dose

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Vz/F is influenced by the fraction absorbed. Vz/F for steady-state axitinb was evaluated on Cycle 2 Day 15.

Comparison of the Ratio of CECs in Blood: CD146+/CD105+ at Each Time Point to BaselineAt end of the lead-in period (Cycle 1 Day 15), Cycle 2 Day 15 and End of therapy (EOT)
