2. Criterion amended per Amendment 1:
2.1 Histologic demonstration of an unresectable, locally advanced, or metastatic solid tumor malignancy bearing an FGFR mutation or fusion, as determined by local* or central laboratory screening (Section 8.1.1.1). Note that central creening for breast cancer is limited to women with hormone-sensitive (ie, estrogen positive [ER]/progesterone positive [PR]) breast cancer
*Subjects with target FGFR mutations or any** FGFR gene fusions are eligible for enrollment in the Broad Panel Cohort (The List of Target FGFR Mutations is provided in Section 10.11)
*Subjects with other FGFR mutations not captured in the Broad Panel Cohort are eligible for enrollment in the Exploratory Cohort
*local testing from tissue or blood with NGS tests performed in Clinical laboratory Improvement Amendments (CLIA)-certified or equivalent laboratories or results from commercially available NGS tests
** FGFR gene fusions must have an intact FGFR kinase domain (include exon 16, 17, or 18). FGFR gene identifiers are provided for reference (see protocol section 5.1).

6. Documented progression of disease, defined as any progression that requires a change in treatment, prior to full study screening
7. Toxicities from previous anticancer therapies should have resolved to baseline levels or to Grade 1 or less except for alopecia, peripheral neuropathy, and Grade 2 laboratory values eligible per Inclusion Criterion 9.
8. For adults (=18 years of age), ECOG performance status Grade 0 or 1 (Section 10.5)
For adolescents (=12 to <16 years of age), Lansky Score of =80 (Section 10.6).
For adolescents (=16 to <18 years of age), Karnofsky Score of =80 (Section 10.6).
9. Criterion amended per Amendment 1
9.1. Adequate bone marrow, liver, and renal function:
a. Bone marrow function (without the support of cytokines or erythropoiesis-stimulating agent in preceding 2 weeks):
-Asolute neutrophil count (ANC) =1,000/mm3
-Patelet count =75,000/mm3
-Hemoglobin =8.0 g/dL
b. Liver function:
-Total bilirubin =1.5 x institutional ULN OR direct bilirubin =ULN for subjects with total bilirubin levels >1.5xULN
-Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =2.5x nstitutional ULN or =5x institutional ULN for subjects with liver metastases
c. Renal function: Creatinine clearance >30 mL/min/1.73m2 either directly measured via 24-hour urine collection or calculated using the Cockcroft-Gault formula for adult subjects or the CKiD (Chronic Kidney Disease in Children)Schwartz formula for adolescent subjects (Section 10.7)
d. Phosphate: 10. Must sign an ICF (or their legally acceptable representative must sign)idicating that he or she understands the nature, significance, and purpose of the study, and procedures required for the study, and consequence of the study; and is willing to participate in the study. For adolescent subjects, parent(s) (preferably both if available or as per local requirements) (or their legally acceptable represe
1. Has had prior chemotherapy, targeted therapy, or treatment with an investigational anticancer agent within 30 days or =5 half-lives of the agent (whichever is longer) before the first dose of erdafitinib. Has had prior immunotherapy within 30 days before the first dose of erdafitinib and/or has an ongoing Grade =2 immunotherapyrelated toxicity

3. Criterion amended per Amendment 1
3.1. For NSCLC subjects only - pathogenic somatic mutations or gene fusions in the following genes: EGFR, ALK, ROS1, NTRK, and BRAF V600E (PIK3CA and PTEN alteration status must be known at the time of enrollment for retrospective data analysis)
