What was measured

Percentage of participants achieving a best objective response of partial response (PR) or complete response (CR) per RECIST 1.1, by up to 24 weeks after all participants have completed response assessment. Response assessment was determined by investigator. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must had reduction in the short axis to less than (\<) 10 millimeters (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Analysis population: The FAS included all participants who receive at least 1 dose of study drug.

Groups in this outcome

Eribulin Mesylate 1.4 mg/m^2: RMS

Pediatric participants with RMS received eribulin mesylate as an IV infusion on Days 1 and 8 of each 21-day cycle at a dose of 1.4 mg/m\^2. Participants continued to receive study therapy until progression of disease, (per RECIST 1.1), exhibited no clinical benefit, intolerable toxicity, withdrawal of consent or termination of the study program, whichever occurred first.

Eribulin Mesylate 1.4 mg/m^2: NRSTS

Pediatric participants with non-rhabdomyosarcoma solid tumor sarcoma (NRSTS) received eribulin mesylate as an IV infusion on Days 1 and 8 of each 21-day cycle at a dose of 1.4 mg/m\^2. Participants continued to receive study therapy until progression of disease, (per RECIST 1.1), exhibited no clinical benefit, intolerable toxicity, withdrawal of consent or termination of the study program, whichever occurred first.

Eribulin Mesylate 1.4 mg/m^2: EWS

Pediatric participants with EWS received eribulin mesylate as an IV infusion on Days 1 and 8 of each 21-day cycle at a dose of 1.4 mg/m\^2. Participants continued to receive study therapy until progression of disease, (per RECIST 1.1), exhibited no clinical benefit, intolerable toxicity, withdrawal of consent or termination of the study program, whichever occurred first.
