An Open-Label, Multicenter, Phase 1b/2 Study of E7080 Alone, and in Combination With Everolimus in Subjects With Unresectable Advanced or Metastatic Renal Cell Carcinoma Following One Prior VEGF-Targeted Treatment

Phase 1b: Number of Participants With Dose-limiting Toxicity (DLT)

时间窗: First dose of study drug (Cycle 1 Day 1) to end of first 4 weeks of therapy (Cycle 1)

A DLT was defined as either a treatment-related failure to administer greater than or equal to (\>=) 75% of the planned dosage of lenvatinib/everolimus or a specific National Cancer Institute Common Toxicity Criteria (NCI CTC) \>= Grade 3 (severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care daily living activities) hematologic or nonhematologic toxicities considered to be possibly related to lenvatinib and/or everolimus therapy assessed during the first treatment cycle of each dose level. Higher grade indicates more severe toxicity.

Phase 1b: Maximum Tolerated Dose (MTD) and Recommended Phase 2 (RP2) Dose

时间窗: First dose of study drug (Cycle 1 Day 1) to end of Cycle 2 (1 cycle = 28 days/4 weeks)

The highest dose level resulting in 0 or 1 DLT in 6 participants was to be considered the MTD of Phase 1b. Once the MTD was established, the participant cohort was expanded to a minimum of 10 participants. The MTD was confirmed by assessing DLTs during Cycle 1 and intolerable toxicities (i.e., not manageable with dose interruption and/or reduction) during Cycle 2 of therapy. Once the dose of lenvatinib/everolimus combination to be used in the succeeding Phase 2 part of the study was established, enrollment into Phase 2 was started. The RP2 dose was the same as the confirmed MTD and was used for the Phase 2 Treatment Arm A of this study.

Phase 2: Progression-Free Survival (PFS)

时间窗: Date of randomization into Phase 2 (Cycle 1 Day 1) to the date of first documentation of disease progression or death (whichever occurred first), assessed up to data cutoff date (13 Jun 2014), up to approximately 2 years and 3 months

PFS was defined as the time (in months) from the date of first dose of study drug to the first documentation of disease progression or death, whichever occurred first. Kaplan-Meier (K-M) estimates were used to estimate median PFS, presented with 2-sided 95% confidence intervals (CIs). Tumor assessments were performed every 8 weeks (or sooner if there was evidence of progressive disease using computed tomography (CT) or magnetic resonance imaging (MRI) and scan acquisition techniques (including use or nonuse of intravenous (IV) contrast). Tumor response was determined at the site by the investigator and radiologist using Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 in the evaluation of the tumor assessment scans. The date of objective disease progression was defined as the earliest date of radiological disease progression. Participants removed from therapy due to clinical progression with no radiologic confirmation were censored at their last radiologic assessment date.
