What was measured

ORR at Week 16 was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) at Week 16 based on investigator assessment according to response evaluation criteria in solid tumors (RECIST) version 1.1 for non-HGG cohorts and response assessment in neuro-oncology (RANO) for HGG cohort. CR was defined as 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 less than (\<) 10 millimeter (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameter (SOD) of target lesions, taking as reference the baseline sum diameters.

Analysis population: Evaluable analysis set included all evaluable participants who have measurable disease present at baseline, and at least one postbaseline efficacy assessment, unless they have discontinued prior to the first efficacy assessment due to progressive disease.

Groups in this outcome

Phase 2: Cohort 1, Ewing Sarcoma

Participants with recurrent or refractory ewing sarcoma received lenvatinib 11 mg/m\^2, capsules, orally, once daily in combination with everolimus 3 mg/m\^2, tablets, orally, once daily for up to 7 cycles (each cycle was 28 days) unless participant discontinued early from the study.

Phase 2: Cohort 2, Rhabdomyosarcoma

Participants with recurrent or refractory rhabdomyosarcoma received lenvatinib 11 mg/m\^2, capsules, orally, once daily in combination with everolimus 3 mg/m\^2, tablets, orally, once daily for up to 7 cycles (each cycle was 28 days) unless participant discontinued early from the study.

Phase 2: Cohort 3, HGG

Participants with recurrent or refractory HGG received lenvatinib 11 mg/m\^2, capsules, orally, once daily in combination with everolimus 3 mg/m\^2, tablets, orally, once daily for up to 7 cycles (each cycle was 28 days) unless participant discontinued early from the study.
