New hope for kids with tough cancers: targeted drug shows promise in Gene-Matched tumors
NCT ID NCT03210714
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a drug called erdafitinib in children and young adults (ages 1 to 21) whose cancers have come back or are not responding to treatment and have specific changes in FGFR genes. The drug works by blocking enzymes that help cancer cells grow. The main goal is to see how many patients' tumors shrink or disappear.

\>/= 150 days after TBI, craniospinal XRT or if radiation to \>/= 50% of the pelvis; \>/= 42 days if other substantial bone marrow (BM) radiation * Note: radiation may not be delivered to "measurable disease" tumor site(s) being used to follow response to subprotocol treatment * Radiopharmaceutical therapy (e.g., radiolabeled antibody, iobenguane I-131 \[131I-MIBG\]): \>/= 42 days after systemically administered radiopharmaceutical therapy * Patients must not have received prior exposure to erdafitinib or another FGFR inhibitor such as (but not limited to) AZD4547, BGJ398, BAY1163877, LY2874455 * For patients with solid tumors without known bone marrow involvement: * Peripheral absolute neutrophil count (ANC) \>/= 1000/mm\^3 (performed within 7 days prior to enrollment) * Platelet count \>/= 100,000/mm\^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment) (performed within 7 days prior to enrollment) * Hemoglobin \>/= 8.0 g/dL at baseline (may receive red blood cell \[RBC\] transfusions) (performed within 7 days prior to enrollment) * Patients with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts (may receive platelet or packed \[p\]RBC transfusions provided they are not known to be refractory to red cell or platelet transfusions); these patients will not be evaluable for hematologic toxicity * Creatinine clearance or radioisotope glomerular filtration rate (GFR) \>/= 70 ml/min/1.73 m\^2 or a serum creatinine based on age/gender as follows (performed within 7 days prior to enrollment): * Age: 1 to \< 2 years;
