Secondary Objectives:
To assess (PFS) and (OS) of subjects in this study population when treated with E7080.

To assess the safety and tolerability of E7080.
To assess the pharmacokinetics profile and pharmacodynamics of E7080 in subjects with advanced endometrial cancer.
Exploratory Objectives:
To explore the effect of E7080 as a function of dose/exposure on tumour volumes (i.e., as a biomarker of effect on biological growth rate).
To assess the anti-angiogenic effect of E7080 on endometrial carcinomas using DCE-MRI metrics and the direct anti-tumor effect using DWI-MRI metrics at selected sites.
To identify and evaluate genetic, blood and tumor biomarkers with respect to the efficacy related endpoints of this study.

If there is only 1 target lesion, and it is a non-lymph node, it should have a longest diameter of ≥1.5 cm (revised per Amendment 02).
─ Lesions that have had external beam radiotherapy (EBRT) or loco-regional therapies such as radiofrequency (RF) ablation must show evidence of progressive disease based on RECIST 1.1 to be deemed a target lesion.
4) ECOG performance status >/=2
5) Adequately controlled BP with or without antihypertensive medications defined as BP <150/90mmHg at screening and no change in antihypertensive medications within 1 week prior to Screening Visit.
6) Adequate renal function defined as calculated creatinine clearance >/=30 mL/min per Cockcroft and Gault formula
7) Adequate bone marrow function:

-Hemoglobin >/=9.0 g/dL
8) Adequate blood coagulation function as evidenced by an INR </=1.5
9) Adequate liver function:
-Bilirubin </=1.5 x ULN except for unconjugated hyperbilirubinaemia of Gilbert's syndrome
-ALT and AST </=3 x ULN (</=5 x ULN if subject has liver metastases)
10) Females age >/=18 years at the time of informed consent
11) Females must not be lactating or pregnant at Screening or Baseline (as documented by a negative beta-human chorionic gonadotropin [ß-hCG] test with a minimum sensitivity of 25 IU/L or equivalent units of ß-hCG). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug. (revised per Amendment 02)
12) All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing) (revised per Amendment 02).
13) Females of childbearing potential must not have had unprotected sexual intercourse within 30 days prior to study entry and must agree to use a highly effective method of contraception (e.g., total abstinence, an intrauterine device, a double-barrier method [such as condom plus diaphragm with spermicide], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double-barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. Females who are using hormonal contraceptives must have been on a stable dose of the same hormonal contraceptive product for at least 4 weeks prior to dosing and must continue to use the same contraceptive during the study and for 30 days after study drug discontinuation (Revised per Amendment 02). |

7) Inability to take oral medication
8) Major surgery within 3 weeks prior to the first dose of study drug

E.5 End points |
E.5.1 | Primary end point(s) |
Objective tumor response rate (CR + PR) based on RECIST 1.1 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
All response rates will be based on RECIST 1.1. The ORR in Stage I of Simon’s Optimal Two-Stage Design will be determined while the first 47 subjects (Per Protocol Population) complete a minimum of 6 cycles of treatment (or have discontinued study drug prior to completing 6 cycles). This analysis will be based on investigator assessments of tumor response to decide if the study should continue enrollment to complete Stage II. The final analysis of ORR will utilize tumor response assessments as determined by independent radiologic review (IRR). Data cut-off for the final (primary) analysis will occur at the end of the Treatment Phase. This analysis will be performed on the Full Analysis Population (ITT Analysis Set). |

E.5.2 | Secondary end point(s) |
Progression-free survival based on RECIST 1.1 and measured as the time from the date of first treatment until the date of first documentation of disease progression or date of death, if death occurs prior to disease progression.
