Brief summary
This is a Phase 1 study of eribulin mesylate in pediatric participants with recurrent or refractory solid tumors (excluding CNS), including lymphomas. Eribulin mesylate will be administered intravenously, once per day on Days 1 and 8 of a 21-day cycle. This study aims to determine the maximum tolerated dose (MTD) and/or the Recommended Phase 2 Dose (RP2D) of this regimen in Part A1 (participants greater than or equal to \[\>=\] 12 months and less than \[\<\] 18 years). Part A2 will enroll infants (greater than \[\>\] 6 months and \<12 months) one dose level behind the dose level at which participants in Part A1 are enrolling, in order to maximize safety for infant participants. Additionally, this study aims to describe the toxicities and the pharmacokinetics of eribulin mesylate when administered to children. In a preliminary manner, the antitumor effect of eribulin mesylate will also be described.

An AE was defined as any untoward medical occurrence in a participants or clinical investigation participant administered an investigational product. An AE does not necessarily have a causal relationship with medicinal product. A SAE was defined as any AE if it resulted in death or life-threatening AE or required inpatient hospitalization or prolongation of existing hospitalization or resulted in persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions or was a congenital anomaly/birth defect.
Time frame: First dose of study drug (Baseline) up to 30 days after last dose of study drug (Cycle 8 Day 38)
Population: The SAS included all participants who received at least one dose of study drug.

Secondary
Number of Participants With Best Overall Response
Best Overall Response (BOR): best response recorded from start of study treatment until disease progression (PD) or recurrence based on response evaluation criteria in solid tumors (RECIST) version 1.1 for target and non-target lesions. Participants with evaluable disease were also eligible for assessment.
Time frame: First dose of study drug (Baseline) up to approximately Cycle 8 (21-days treatment cycle)
Population: The SAS included all participants who received at least one dose of study drug.
