A Study of Cabozantinib as a Maintenance Agent to Prevent Progression or Recurrence in High-Risk Pediatric Solid Tumors

Is NCT05135975 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Cabozantinib for neuroblastoma.

Phase 2RecruitingNationwide Children's HospitalNCT05135975Data as of May 2026

Treatment: CabozantinibThis study will expand the types of pediatric cancers being evaluated for response to cabozantinib. The current COG study is restricted to Ewing sarcoma, osteosarcoma, rhabdomyosarcoma, Wilms tumor, and a handful of uncommon tumors. The proposed study will extend this evaluation to tumors that have been shown to either express known targets of cabozantinib or with preclinical evidence of efficacy, including specifically neuroblastomas. These tumors have high morbidity and mortality, particularly in the relapse setting, and few or no proven therapeutic options. As such, evaluation of cabozantinib in these studies is warranted. The study hypothesizes that use of cabozantinib in patients with ultra-high-risk pediatric solid tumors with minimal disease burden, as defined in the inclusion criteria below, can prevent and/or slow recurrent tumor formation in pediatric solid tumors and thereby significantly extend the period of disease control and/or induce a durable cure.
