BGJ398 in Treating Patients With FGFR Positive Recurrent Head and Neck Cancer

Study Overview
=================
Brief Summary
-----------------
This phase IIa trial studies how well the experimental drug, BGJ398 (infigratinib), works in treating patients with fibroblast growth factor receptor (FGFR) 1-3 translocated, mutated, or amplified head and neck cancer that has returned after a period of improvement. BGJ398 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

patients with leptomeningeal involvement are excluded Patients who received a prior selective FGFR inhibitor in the recurrent/metastatic disease setting; prior use of a multikinase inhibitor that includes anti-FGFR activity is acceptable after review by the lead investigator History and/or current evidence of tissue calcification including, but not limited to, the soft tissue, kidneys, intestine, myocardium and lung with the exception of calcified lymph nodes and asymptomatic coronary calcification Current evidence of corneal or retinal disorder/keratopathy including, but not limited to, bullous/band keratopathy, corneal abrasion, inflammation/ulceration, keratoconjuctivitis, confirmed by ophthalmologic examination Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral BGJ398 (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection) History and/or current evidence of endocrine alterations of calcium/phosphate homeostasis, e.g., parathyroid disorders, history of parathyroidectomy, tumor lysis, tumoral calcinosis, etc unless approval from lead investigator/ collaborator is obtained Treatment with any of the following anti-cancer therapies prior to the first dose of BGJ398 within the stated timeframes Cyclical chemotherapy (intravenous) within a period of 2 weeks unless there are ongoing side effects > grade 2 Biological therapy (including small molecules, and/or) within a period of time that is =< 2 weeks prior to starting study drug unless there are ongoing side effects > grade 2 Any other investigational agents within a period =< 2 weeks prior to starting study drug unless there are ongoing side effects > grade 2 Wide field radiotherapy (including radioisotopes) =< 2 weeks prior to starting study drug unless there are ongoing side effects > grade 2 Patients who are currently receiving treatment with agents that are known strong inducers or inhibitors of cytochrome P450 family 3, subfamily A, polypeptide 4 (CYP3A4) are prohibited Enzyme inducing anti-epileptic drugs Consumption of grapefruit, grapefruit juice, pomegranates, star fruits, Seville oranges or products within 7 days prior to first dose Use of medications that are known to prolong the QT interval and/or are associated with a risk of torsades de pointes 7 days prior to first dose Use of amiodarone within 90 days prior to first dose Use of medications that increase serum levels of phosphorus and/or calcium Current use of therapeutic doses of warfarin sodium or any other coumadin-derivative anticoagulants; heparin and/or low molecular weight heparins or other anticoagulants are allowed Insufficient bone marrow function Absolute neutrophil count (ANC) < 1,000/mm^3 [1.0 x 10^9/L] Platelets < 75,000/mm^3 [75 x 10^9/L] Hemoglobin < 10.0 g/dL Insufficient hepatic and renal function Total bilirubin > 1.5 x upper limit of normal (ULN) (unless evidence of Gilbert's disease) Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum glutamate pyruvate transaminase (SGPT) > 2.5 x ULN Serum creatinine >= ULN and/or calculated or measured creatinine clearance < 75% lower limit of normal (LLN) Calcium-phosphate homeostasis Inorganic phosphorus outside of normal limits Total and ionized serum calcium outside of normal limits Clinically significant cardiac disease including any of the following: Congestive heart failure requiring treatment (New York Heart Association [NYHA] grade >= 2) Left ventricular ejection fraction (LVEF) < 50% as determined by multigated acquisition (MUGA) scan or electrocardiogram (ECHO), or uncontrolled hypertension (refer to World Health Organization-International Society of Hypertension [WHO-ISH] guidelines) History or presence of clinically significant ventricular arrhythmias, atrial fibrillation, resting bradycardia, or conduction abnormality Unstable angina pectoris or acute myocardial infarction =< 3 months prior to starting study drug Corrected QT Interval Fridericia (QTcF) > 450 msec (both genders) History of congenital long QT syndrome Pregnant or nursing (lactating) women Known positive serology for human immunodeficiency virus (HIV), active hepatitis B, and/or active hepatitis C infection Study medication cannot be administered through gastric (G)-tube, unless additional information from the manufacturer becomes available in the future Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 3 months following the discontinuation of study treatment must be used by both sexes (= female patients and their male partners) Post-menopausal women are allowed to participate in this study; women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential Sexually active males unless they use a condom during intercourse while taking drug and for 3 months after the last dose of the study drug and should not father a child in this period; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid
