Measureable disease meeting the following criteria: At least 1 lesion of greater than 1.0 cm in the longest diameter for a non-lymph node or greater than 1.5 cm in the short-axis diameter for a lymph node which is serially measureable according to modified RECIST 1.1 using computerized tomography / magnetic resonance imaging. Lesions that have had external beam radiotherapy (EBRT) or loco-regional therapies such as radiofrequency ablation must show evidence of progressive disease based on modified RECIST 1.1 to be deemed a target lesion. Eastern Cooperative Oncology Group (ECOG) performance status less than 2. Adequate controlled blood pressure (BP) with or without antihypertensive medications, defined as BP less than 150/90 mmHg at screening and no change in antihypertensive medications within 1 week prior to the Screening Visit. Adequate renal function defined as calculated creatinine clearance greater than 30 mL/min per the Cockcroft and Gault formula. Adequate bone marrow, blood coagulation, and liver functions, as defined in the study protocol. Negative serum or urine pregnancy test for women of reproductive potential. Exclusion criteria: Brain or leptomeningeal metastases, including stable metastases. More than 1 prior systemic chemotherapy regimen for recurrent metastatic or primary unresectable endometrial carcinoma or any treatment targeting vascular endothelial growth factor (VEGF)-directed angiogenesis. No restriction regarding prior adjuvant chemotherapy or hormonal therapy. Prior systemic anti-tumor therapy within 3 weeks. Not fully recovered from prior radiotherapy based on investigator judgement. Participants with greater than 1+ proteinuria on urine dipstick testing to undergo 24-hour urine collection for quantitative assessment of proteinuria. Participants with greater than 1 gm will be ineligible. Significant cardiovascular impairment: history of congestive heart failure greater than New York Heart Association Class II; unstable angina; myocardial infarction or stroke within 6 months of the first dose of study drug; cardiac arrhythmia requiring medical treatment. Prolongation of QTc interval greater than 480 msec. Bleeding disorder or thrombotic disorders requiring anticoagulant therapy, such as warfarin, or similar agents requiring therapeutic INR monitoring (treatment with low molecular weight heparin [LMWH] allowed). Active hemoptysis within 3 weeks prior to the first dose of study drug. Females who are pregnant or breast feeding.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Lenvatinib 24 mg<br>Participants with advanced endometrial cancer and disease progression following platinum-based, first line chemotherapy. | Drug: Lenvatinib<br>* Lenvatinib 24 mg administered orally, once daily continuously in 28-day cycles to participants with advanced endometrial cancer and disease progression following first-line chemotherapy. Participants continued to receive study drug until disease progression, development of unacceptable toxicity or withdrawal of consent. 'Treatment interruption and subsequent dose reduction' was allowed for participants who experienced lenvatinib-related toxicity.<br>* Other names: E7080, Lenvima;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective Response Rate (ORR) | ORR was defined as the percentage of participants with best overall response (BOR) of complete response (CR) or partial response (PR) based on Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 for target lesions assessed by magnetic resonance imaging/computed tomography (MRI/CT) scans, as determined by independent radiologic review. BOR of CR was confirmed by a subsequent CR assessment at least 4 weeks later. BOR of PR was confirmed by a subsequent CR or PR assessment at least 4 weeks later. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in short axis to <10 mm. PR was defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters. The null hypothesis ORR was ≤10% was tested using 1-sided exact test of a single proportion, at 1-sided 0.05 level. ORR was presented with corresponding 2-sided, 95% confidence interval (CI). ORR=CR+PR | From the date of first administration of study treatment until all participants completed a minimum of 6 cycles (28-day cycles) or discontinued treatment prior to the end of Cycle 6 (as of 21 May 2012 data cut-off) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival (PFS) | PFS was measured as the time from the date of first administration of study treatment until the date of first documentation of disease progression or date of death (whichever occurred first), as determined by independent radiologic review (IRR) and Investigator based on RECIST 1.1. 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. | From date of first administration of study treatment until the date of first documentation of disease progression or date of death, if death occurred prior to disease progression or up to approximately 26 months (as of 21 May 2012 data cut-off) | 
| Overall Survival (OS) | OS was the length time in months from the date of first treatment until the date of death from any cause. If death was not observed, OS was censored at the last known alive date or data cut-off. Additional survival follow-up data was collected for all participants who had not withdrawn consent and were alive at the time of the initial survival follow-up as of 26 Nov 2012 data cut-off. Participants who were lost to follow-up at the time of the initial assessment may have been contacted again at the investigator's discretion. Updated survival (based on 26 Nov 2012 cut-off) was derived for these participants if the contact was made successfully. | From date of first administration of study treatment until the date of death, or up to approximately 32 months (as of 26 Nov 2012 data cut-off) | 
| Disease Control Rate (DCR) | DCR was defined as the percentage of participants with BOR of CR or PR or stable disease (SD) based on RECIST 1.1 and SD lasting greater than or equal to 7 weeks, as determined by IRR and Investigator. | From date of first administration of study treatment until the date of first documentation of disease progression or date of death, if death occurred prior to disease progression, or up to approximately 26 months (as of 21 May 2012 data cut-off) | 
| Clinical Benefit Rate (CBR) | CBR was defined as the percentage of participants with BOR of CR or PR or durable stable disease (dSD) [CR + PR + dSD] based on RECIST 1.1. The dSD rate was defined as the percentage of participants with dSD (based on RECIST 1.1 and defined as SD lasting greater than or equal to 23 weeks), as determined by the IRR and Investigator. | From date of first administration of study treatment until the date of first documentation of disease progression or date of death, if death occurred prior to disease progression, or up to approximately 26 months (as of 21 May 2012 data cut-off) | 
| Number of Participants With Adverse Events (AEs) /Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability of Lenvatinib Tolerability of Lenvatinib | Safety was assessed by monitoring and recording all AEs and SAEs, regular monitoring of hematology, clinical chemistry, and urine values, regular measurement of vital signs, electrocardiograms (ECGs), and echocardiograms. | From the administration of first dose up to 30 days after the last dose, or up to data cut-off (21 May 2012), or up to approximately 26 months. |
