Inclusion criteria
Inclusion criteria: 1. Histologically or cytologically confirmed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx, not amenable for salvage surgery or radiotherapy. 2. Measuarable disease as defined per RECIST v. 1.1. Tumor lesions previously irradiated or subjected to other locoregional therapy will only be deemed measureable if disease progression at the treated site after completion of therapy is clearly documented. 3. HPV-negative SCCHN tumor as determined per institutional standard (eg, p16 IHC; multiplex nucleic acid sequence based amplification [NASBA] or other polymerase chain reaction [PCR]-based assays). 4. Documented progressive disease according to RECIST v1.1 following receipt of at least 2 cycles of one platinum-containing chemotherapy regimen administered for R/M disease (min. 50 mg/m2 for cisplatin, minimum area under the curve [AUC] >4 for carboplatin). 5. Availability of a tumor tissue specimen (ie, archived formalin fixed paraffin embedded tissue [block preferred, or 15 unstained slides]), which will be used for centralized, retrospective biomarker analysis. If archived tumor tissue is not available, then a de novo biopsy will be required for patient participation. 6. ECOG performance status (PS) 0 or 1. 7. Adequate organ and marrow function defined as follows: - Leukocytes >3,000/mm3 (3.0 x 1.000.000.000/L); - Absolute Neutrophil count (ANC) = 1,200/mm3 (1.2 x 1.000.000.000/L); - Platelets = 75,000/mm3 (75 x 1.000.000.000/L); - Hemoglobin (Hb) = 9 g/dL (90 g/L); - Serum creatinine = 1.5 x upper limit of normal (ULN) or estimated creatinine clearance = 40 mL/min as calculated using the method standard for the institution; - Total serum bilirubin = 1.5 x ULN (= 3.0 x ULN if Gilbert’s disease); - Asparate aminotransferase (AST) and/or alanine aminotransferase (ALT) = 2 x ULN (= 5.0 x ULN if liver metastases present); - Alkaline phosphatase = 2.5 x ULN (= 5.0 x ULN if bone or liver metastases present). 8. Male and female patients of childbearing potential and at risk for pregnancy must agree to use two highly effective methods of contraception throughout the study and for 6 months after the last dose of cetuximab. Female subjects who are not of childbearing potential (ie, meet at least 1 of the following criteria): - Have undergone a documented hysterectomy and/or bilateral oophorectomy; - Have medically confirmed ovarian failure; or - Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; status may be confirmed by having a serum follicle stimulating hormone (FSH) level within the laboratory’s reference range for postmenopausal women. 9. Age = 18 years (or = 20 years as applicable by local country regulations). 10. Evidence of a personally signed and dated informed consent document indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the study. 11. Patients who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 96 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 24
Exclusion criteria
Exclusion criteria: 1. Prior nasopharyngeal cancer, salivary gland or sinus tumors. 2. More than one chemotherapeutic regimen given for R/M disease. Prior treatment with immunotherapy is allowed. 3. Known active uncontrolled or symptomatic central nervous system (CNS) metastases, carcinomatous meningitis, or leptomeningeal disease as indicated by clinical symptoms, cerebral edema, and/or progressive growth. Patients with a history of CNS metastases or cord compression are eligible if they have been definitively treated with local therapy (eg, radiotherapy, stereotactic surgery) and are clinically stable off anticonvulsants and steroids for at least 4 weeks before randomization. 4. Progressive disease within 3 months after completion of curatively intended treatment for locoregionally advanced SCCHN. 5. Inability to swallow capsules. 6. Prior use of cetuximab in the R/M disease treatment setting. 7. Prior treatment with any CDK4/6 or EGFR inhibitor (except cetuximab during curative radiotherapy). 8. Patients treated within the last 7 days prior to randomization with: - Food or drugs that are known to be strong CYP (cytochrome P-450) 3A4 inhibitors (ie, amprenavir, atazanavir, boceprevir, clarithromycin, conivaptan, delavirdine, diltiazem, erythromycin, fosamprenavir, indinavir, itraconazole, ketoconazole, lopinavir, mibefradil, miconazole, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telaprevir, telithromycin, verapamil, voriconazole, and grapefruit or grapefruit juice); - Drugs that are known to be strong CYP3A4 inducers (ie, carbamazepine, felbamate, nevirapine, phenobarbital, phenytoin, primidone, rifabutin, rifampin, rifapentin, and St. John’s wort); - Drugs that are known to prolong the QT interval. 9. Major surgery, chemotherapy, radiotherapy, any investigational agents, or other anti-cancer therapy within 2 weeks before randomization. Patients who received prior radiotherapy to = 25% of bone marrow are not eligible independent of when it was received. 10. Diagnosis of any other malignancy within 3 years prior to randomization, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the cervix. 11. QTc >480 msec (based on the mean value of the triplicate electrocardiograms (ECGs), family or personal history of long or short QT syndrome, Brugada syndrome or known history of QTc prolongation, or Torsade de Pointes. 12. Uncontrolled electrolyte disorders that can compound the effects of a QTc-prolonging drug (eg, hypocalcemia, hypokalemia, hypomagnesemia. 13. Any of the following within 6 months of randomization: myocardial infarction, severe/unstable angina, ongoing cardiac dysrhythmias of NCI CTCAE version 4.03 Grade = 2, atrial fibrillation of any grade, coronary/peripheral artery bypass graft, symptomatic congestive heart failure, cerebrovascular accident including transient ischemic attack, or symptomatic pulmonary embolism. 14.
