What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS)	PFS=time from randomization date to date of first documentation of progressive disease (PD; defined as greater than or equal to [≥]20% increase in sum of longest dimensions of target lesions taking as a reference smallest sum of longest dimensions recorded since first dose or appearance of ≥1 new lesions) or death on-study due to any cause, whichever occurred first based on third party independent imaging review laboratory assessment. PFS calculated as (first event date minus randomization date plus 1) divided by 7.02. Used 7.02 days as it equals 365 days per year divided by 52 weeks per year.	From randomization to Weeks 8 and 12, then every 8 weeks until disease progression or death (up to Month 17)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Objective Response	Objective Response Rate (ORR)=participants with confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST,Version 1.0) based on third party independent imaging review laboratory assessment. A CR was defined as the disappearance of all target lesions that persisted on repeat imaging study at least 4 weeks after initial documentation of response. A PR was defined as a ≥30% decrease in sum of longest dimensions of target lesions taking as a reference the baseline sum longest dimensions.	From randomization to Weeks 8 and 12, then every 8 weeks until disease progression or death (up to Month 17)
Time to Tumor Progression (TTP)	TTP was defined as the time from date of randomization to first documentation of PD based on third party independent imaging review laboratory assessment. TTP was calculated as (first event date minus randomization date plus 1) divided by 7.02.	From randomization to Weeks 8 and 12, then every 8 weeks until disease progression or death (up to Month 17)
Duration of Response (DR)	DR was defined as time from first documentation of objective tumor response (CR or PR) that was subsequently confirmed to the first documentation of PD or death on-study due to any cause, whichever occurred first.

Health Related Quality of Life (HRQoL) and Lung Cancer Related Symptoms as Assessed With European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) Score	EORTC QLQ-C30: self-administered questionnaire assessing global health status/quality of life (QoL), functional domains (physical, role, cognitive, emotional, and social), symptom scales/items (fatigue, pain, nausea and vomiting, dyspnea, insomnia, loss of appetite, constipation, and diarrhea), and financial difficulties. Recall period: past week; response range: not at all (1) to very much (4); global/QoL range: very poor (1) to excellent (7). Scale score range: 0 to 100. Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.	Baseline (Cycle [C] 1, Day [D] 1) to Cycle 18, Day 1
EORTC-QLQ-C30 Lung Cancer Module (LC13) Score	The EORTC-QLQ-C30 LC13 is a self-administered questionnaire assessing specific lung cancer disease related symptoms (dyspnea, coughing, hemoptysis, sore mouth, dysphagia, peripheral neuropathy, alopecia, pain in the chest, arm/shoulder or other parts of the body). Recall period: past week; response range: not at all (1) to very much (4). Scale score range: 0 to 100. Higher symptom score = greater degree of symptoms.	Baseline (Cycle 1 [Day 1]) to Cycle 18 (Day 1)
Number of Participants With Blood Pressure (BP) Greater Than 150/100 Millimeters of Mercury (mmHg)	Systolic/diastolic BP measured in triplicate (separated by approximately 2 minutes [min]) using validated electronic device (same device for all measurements), recorded to nearest mmHg. Dominant arm used (same one each time) with appropriate cuff size encircling at least 80% of arm. BP measured after 5 min rest and before invasive procedures, while seated in a chair with back supported, arms bared, supported at heart level. No smoking or caffeine use allowed during 30 min before measurement. Number of participants with systolic BP >150 mmHg/diastolic BP >100 mmHg at any timepoint postbaseline.	Randomization up until Month 17
Number of Participants With BP Greater Than 200/110 mmHg	Systolic/diastolic BP measured in triplicate (separated by approximately 2 minutes [min]) using validated electronic device (same device for all measurements), recorded to nearest mmHg. Dominant arm used (same one each time) with appropriate cuff size encircling at least 80% of arm. BP measured after 5 min rest and before invasive procedures, while seated in a chair with back supported, arms bared, supported at heart level. No smoking or caffeine use allowed during 30 min before measurement. Number of participants with systolic BP >150 mmHg/diastolic BP >100 mmHg at any timepoint postbaseline.	Randomization up until Month 17
Number of Participants on Anti-hypertensive Medications	Number of participants with BP greater than 150/100 mmHg or 200/110 mmHg who were treated with anti-hypertensive medications.	Randomization to Day 28 of Cycle 18
Plasma Concentration of VEGF-C at Baseline		Baseline (Cycle 1, Day 1)
Plasma Concentration of Soluble VEGFR-2 at Baseline		Baseline (Cycle 1, Day 1)
Plasma Concentration of Soluble VEGFR-3 at Baseline		Baseline (Cycle 1, Day 1)
Plasma Concentration of Soluble KIT (sKIT) at Baseline		Baseline (Cycle 1, Day 1)

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
VEGF-C Ratio to Baseline at Each Timepoint	Plasma VEGF-C concentration at each time point divided by VEGF-C concentration at baseline (ratio to baseline)	Baseline to Cycle 2 (Day 1) and Cycle 3 (Day 1)
VEGFR-2 Ratio to Baseline at Each Timepoint	Plasma VEGFR-2 concentration at each time point divided by VEGFR-2 concentration at baseline (ratio to baseline)	Baseline to Cycle 2 (Day 1) and Cycle 3 (Day 1)
VEGFR-3 Ratio to Baseline at Each Timepoint	Plasma VEGFR-3 concentration at each time point divided by VEGFR-3 concentration at baseline (ratio to baseline)	Baseline to Cycle 2 (Day 1) and Cycle 3 (Day 1)
sKIT Ratio to Baseline at Each Timepoint	Plasma sKIT concentration at each time point divided by sKIT concentration at baseline (ratio to baseline)	Baseline to Cycle 2 (Day 1) and Cycle 3 (Day 1)
