this is a phase 1 study of eribulin mesylate in pediatric participants with recurrent or refractory solid tumors (excluding [central nervous system] cns), including lymphomas

Conditions: Pediatrics; Solid Tumors

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 \[\ \] 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.
