  9. Washout before Cycle 1 Day 1 of 3 weeks in case of prior chemotherapy, 6 weeks if treatment included nitrosoureas; 4 weeks for definitive radiotherapy, 2 weeks for palliative radiotherapy; and 3 months from high-dose chemotherapy and stem cell rescue. For all other anti-cancer therapies, washout before Cycle 1 Day 1 of at least 5 half-lives (or at least 28 days, whichever is shorter). Participants must have recovered [to Grade <=1, except for alopecia, ototoxicity, and Grade <=2 peripheral neuropathy, per common terminology criteria for adverse events (CTCAE) v5.0] from the acute toxic effects of all prior anticancer therapy before Cycle 1 Day 1

  10. Must have no prior history of lenvatinib treatment

Eligibility for optional lenvatinib crossover:

  2. No new systemic anti-cancer medication administered after the last dose of study drugs
  3. Meets all safety parameters listed in the inclusion criteria and none listed in the exclusion criteria
  4. Study is ongoing
Exclusion Criteria
  1. Any active infection or infectious illness unless fully recovered prior to Cycle 1 Day 1 (that is, no longer requiring systemic treatment)

Primary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS) by Independent Imaging Review (IIR) AssessmentFrom the date of randomization to the date of the first documentation of PD or date of death, whichever occurred first (up to 20.5 months)

PFS as assessed by IIR was defined as the time from the date of randomization to the date of the first documentation of PD or date of death (whichever occurred first), as determined using RECIST v1.1. PD was defined as at least a 20 percent (%) increase or 5 millimeter (mm) 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. PFS was analyzed using Kaplan-Meier method.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With PFS at Month 4 (PFS-4m Rate) by IIR AssessmentMonth 4

PFS rate at 4 months as assessed by IIR was defined as the percentage of participants who were alive and without PD at 4 months from the randomization date using RECIST v1.1. PD was defined as at least a 20% increase or 5 mm 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 PFS-4m was estimated using the Kaplan-Meier method.

Objective Response Rate at Month 4 (ORR-4m) by IIR AssessmentMonth 4

ORR-4m was defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR) as determined by IIR using RECIST v1.1 within the first 4 months. CR: defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to less than (\<) 10 mm. PR: defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. 95% confidence interval (CI) of ORR was calculated using the method of Clopper and Pearson.

Change From Baseline in PedsQL Scale: Cancer Module Scale Score at Month 4Baseline and Month 4

HRQoL: PedsQL 3.0 Cancer Module Scale measured pediatric cancer-specific HRQoL. It included assessment of 8 dimensions: pain and hurt (2 items), nausea (5 items), procedural anxiety (3 items), treatment anxiety (3 items), worry (3 items), cognitive problems (3 items - toddlers \[aged 2-4\], 4 items - young children \[aged 5-7\]; 5 items for children aged \>=8 years, adults), perceived physical appearance (3 items), communication (3 items). Each item was reported using a 5-point Likert scale, items were then reverse-scored and linearly transformed to a 0 to 100 scale. Cancer Module total score: sum of all items divided by the number of items answered on all the scales. Total score ranges from 0 to 100, where higher scores=better HRQoL, lower scores=worse HRQoL.

Percentage of Participants With PFS at 1 Year or Month 12 (PFS-1y Rate) by IIR AssessmentMonth 12 or 1 Year

PFS-1y rate as assessed by IIR was defined as the percentage of participants who were alive and without PD at 1 year from randomization date using RECIST v1.1. PD was defined as at least a 20% increase or 5 mm 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. PFS-1y rate was estimated using Kaplan-Meier method.

Percentage of Participants With Overall Survival at 1 Year or Month 12 (OS-1y)Month 12 or 1 Year

OS-1y was defined as the time from the date of randomization to the date of death from any cause assessed up to 1 year. OS was calculated using the Kaplan-Meier method.

Overall Survival (OS)From the date of randomization to the date of death from any cause (up to 37.1 months)

OS was defined as the time from the date of randomization to the date of death from any cause. The median OS was from Kaplan-Meier product-limit estimates and 2-sided 95% CIs from a generalized Brookmeyer and Crowley method.

ORR by IIR AssessmentFrom the date of randomization to the date of the first documentation of CR or PR (up to 20.5 months)

ORR by IIR was defined as the percentage of participants with best overall response of CR or PR determined using RECIST v1.1. CR: defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to \<10 mm. PR: defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. 95% CI of ORR was calculated using the method of Clopper and Pearson.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)From first dose up to 30 days after the last dose of study drug (up to 40.8 months)

TEAE was defined as an adverse event (AE) that emerged during time from first dose to 30 days following last dose of drug, having been absent at pretreatment or reemerged during treatment, having been present at pretreatment but stopped before treatment, or worsened in severity during treatment relative to pretreatment state, when AE was continuous. Serious adverse events (SAE) was defined as untoward medical occurrence that at any dose resulted in death; was life threatening; resulted in persistent or significant disability; was congenital anomaly or medically important due to other reasons than above mentioned criteria.

Treatment Arm A: Plasma Concentration of LenvatinibCycle 1 Day 1: 0.5-4 hours and 6-10 hours post-dose; Cycle 1 Day 15: Pre-dose, 0.5-4 hours and 6-10 hours post-dose; Cycle 2 Day 1: Pre-dose (each Cycle length = 21 days)

Plasma concentration of lenvatinib in participants from Treatment Arm A (Lenvatinib + Ifosfamide + Etoposide) at different time points were reported. As planned, data for this outcome measure was analyzed for treatment arm A only. Lenvatinib concentration in plasma was quantified using a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method.

Change From Baseline in Pediatric Quality of Life Inventory (PedsQL) Scale: Generic Core Scale Score at Month 4Baseline and Month 4

Health-Related Quality of Life (HRQoL): PedsQL 4.0 Generic Core Scale is a multidimensional scale. It included assessment of 4 dimensions: physical functioning (8 items), emotional functioning (8 items), social functioning (8 items), and school functioning (5 items - children greater than or equal to \[\>=\] 5 years, adults; 3 items - toddlers \[aged 2-4 years\]). Each item was reported using a 5-point Likert scale, items were then reverse-scored and linearly transformed to a 0 to 100 scale. Generic Core Scale total score: sum of all the items divided by the number of items answered across all the scales. Total score ranges from 0 to 100, where higher scores=better HRQoL, lower scores=worse HRQoL.

Number of Participants Categorized Based on Overall Palatability and Acceptability Questionnaire Responses for Suspension of LenvatinibCycle 1 Day 1 (Cycle length = 21 days)

The palatability and acceptability of lenvatinib oral suspension formulation was assessed using the Palatability Questionnaire. In the questionnaire, participants were asked to answer palatability and acceptability of lenvatinib suspension considering the following elements: taste, appearance, smell, how does it feel in the mouth and overall acceptability in terms of 7 responses: Super good, really good, good, may be good or may be bad, bad, really bad, super bad. In this outcome measure, number of participants have been reported per their overall palatability and acceptability responses.
