An AE was defined as any untoward medical occurrence in a clinical investigation participant administered with an investigational product. A SAE was defined as any untoward medical occurrence that at any dose; resulted in death, was life-threatening (i.e., the subject was at a risk of death at the time of the event; this did not include an event that hypothetically might have caused death if it had been more severe), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, or was a congenital abnormality/birth defect. In this study, treatment emergent adverse events (TEAEs) (defined as an AE (serious/non-serious) that started/increased in severity on/after the first dose of study medication up to 30 days after the final dose of study medication) were assessed.

Safety was analyzed in Safety Analysis Set defined as all subjects enrolled and randomized to treatment in study, except for those who (i) dropped out prior to receiving any study drug, or (ii) were without any safety assessment following the first dose of study drug.

Event-free survival rate was calculated using Kaplan Meier estimations. The percentage of participants with event free survival up to 6 months and the corresponding 95% confidence interval were estimated for each treatment group. The data presented is based on the data cut-off date of 26 November 2013 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

Event-free survival rate was calculated using Kaplan Meier estimations. The percentage of participants with event free survival up to 1 year and the corresponding 95% confidence interval were estimated for each treatment group. The data presented is based on the data cut-off date of 26 November 2013 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

PFS was defined as the time from the date of the randomization until the date of first documented disease progression according to Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 or date of death from any cause (whichever occurred first), assessed based on investigator's assessment. Disease progression per RECIST v1.1 was defined as at least a 20% relative increase and 5 mm absolute increase in the sum of diameters of target lesions (taking as reference the smallest sum on study), recorded since the treatment started or the appearance of 1 or more new lesions. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

ORR, defined as the percentage of participants who had best overall response (BOR) of complete response (CR) or partial response (PR) as determined by investigator using RECIST 1.1. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had to have reduction in short axis to less than 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. ORR = CR + PR. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

OS was defined as the time from the date of randomization until the date of death from any cause.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

Response duration, defined as the time from the date of the first assessment demonstrating a CR or PR to the date of the first assessment demonstrating progressive disease or death, whichever occurred first. This is an investigator assessed outcome, measured using RECIST 1.1. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had to have reduction in short axis to less than 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Response duration was summarized by including only subjects with events. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using subjects with events.

The percentage of participants with CR, PR, or stable disease (SD) for greater than or equal to 12 weeks. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had to have reduction in short axis to less than 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable disease was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on the study. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

The EORTC QLQ-C30 symptom score, a cancer specific self-reporting questionnaire was composed of 9-symptom scales assessing fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties. All of the multi-item scales and single-item measures ranged in score from 0 to 100. For each domain and item, a linear transformation was applied to standardize the raw score to a range from 0 to 100, with a higher scale score representing a higher response level/ high level of symptomatology / problems. The data is presented as percentage of participants with EORTC QLQ-C30 symptom score achieving clinically significant deterioration on QOL. Participants were considered as deteriorated for a given symptom if the change in score from Baseline was 10 points or higher at any time point after Baseline. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

The EORTC module QLQ-LC13 symptom score was a self-reporting cancer-specific questionnaire composed of 13 questions incorporated into 1 multi-item scale designed to evaluate dyspnea and a series of single items assessing different types of pain, as well as, cough, hemoptysis, dysphagia, sore mouth, alopecia, and peripheral neuropathy. For each domain and item, a linear transformation was applied to standardize the raw score to a range from 0 to 100, with 100 representing the best possible function/QOL, and highest burden of symptoms for symptom domains and single items. The data is presented as percentage of participants with EORTC module QLQ-C13 symptom score achieving clinically significant deterioration on QOL. Participants were considered as deteriorated for a given symptom if the change in score from Baseline was 10 points or higher at any time point after Baseline. The data presented is based on the data cut-off date of 21 January 2014 while the study is still ongoing.

The analysis was performed using the Intent-to-Treat Population, defined as all randomized subjects.

Blood samples were collected for lenvatinib PK analysis. Lenvatinib concentrations from sparse PK sampling were measured. The data is presented as mean nanograms per milliliter +/- Standard deviation of lenvatinib serum concentration.

The analysis was performed using the pharmacokinetic (PK) analysis set defined as all subjects who received at least one dose of study drug and had evaluable PK data.
