Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This is a phase 1/2 study evaluating safety, tolerability, and efficacy of lenvatinib as single-agent, and in combination with chemotherapy (ifosfamide and etoposide) in children and adolescents with refractory or relapsed solid malignancies including differentiated thyroid carcinoma (single agent lenvatinib) and osteosarcoma (single agent and combination lenvatinib).
