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.
