• At least one measurable lesion outside the central nervous system according to Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) A lesion in a previously irradiated area is eligible and to be considered measurable disease as long as there is objective evidence of progression of the lesion prior to study enrollment. Patients with resected primary tumors who have documented metastases are eligible.

• Absolute neutrophil count (ANC) ≥1,500/mm3
• Platelet count ≥100,000/mm3
• Total bilirubin ≤1.5 times the upper limit of normal (ULN). Documented or diagnosed constitutional jaundice such as Gilbert syndrome is allowed if total bilirubin is mildly elevated (<6 mg/dL).
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 times ULN (≤5 times ULN for patients with liver involvement of their cancer)
• Alkaline phosphatase ≤2.5 times ULN (≤5 times ULN for patients with liver involvement of their cancer)
• Amylase and lipase ≤2.5 times ULN
• Serum creatinine ≤1.5 x ULN and glomerular filtration rate (GFR) ≥30 mL/min/1.73 m2, according to the Modified Diet in Renal Disease (MDRD) abbreviated formula

Exclusion criteria

• Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study.

The following previous or concurrent cancer types might be acceptable: cervical carcinoma in situ, treated basal cell carcinoma, locally confined prostate cancer, or any cancer curatively treated >3 years before the start of rogaratinib.

• Symptomatic brain or meningeal or spinal metastases.

Asymptomatic brain or meningeal or spinal metastases are acceptable if all of the following criteria are met:

• Definitive therapy completed >6 months before the start of rogaratinib
• No evidence of the growth of brain or meningeal or spinal metastases on an imaging test performed within 4 weeks before the start of rogaratinib
• Clinically and radiologically stable with respect to the tumor at the time of study entry

• Moderate or severe liver cirrhosis (Child-Pugh class B or C)
• History or current evidence of altered endocrine regulation of calcium phosphate homeostasis (e.g. parathyroidectomy, parathyroid disorder, tumor lysis, tumoral calcinosis)
• Any previous drug / procedure-related toxicity (patients with persistent alopecia, anemia, and / or hypothyroidism can be included) not recovered to National Cancer Institute's Common Terminology Criteria for Adverse Event, version 4.03 (CTCAE v4.03) Grade 0 or 1 or not recovered to baseline preceding the prior treatment
• Current diagnosis of any retinal disorders including retinal detachment, retinal pigment epithelial detachment (RPED), serous retinopathy or retinal vein occlusion.
• Previous treatment with anti-FGFR directed therapies (e.g. receptor tyrosine kinase inhibitors including rogaratinib or FGFR-specific antibodies)
