Neoadjuvant Afatinib Window Study in Squamous Cell Carcinoma of the Head and Neck

Inclusion Criteria:

* Newly diagnosed histologically proven squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx.
* Patients selected for a primary surgical treatment
* Age ≥18 years
* Performance status ECOG 0-1
* Within 2 weeks prior randomization:

  * Adequate bone marrow function as demonstrated by neutrophils count ≥ 1,500/mm3, platelet count ≥ 75,000/mm3, WBC ≥ 3.0/109 L
  * Adequate hepatic function as demonstrated by bilirubin \< 2 times upper limit of normal (ULN), ALAT or ASAT \< 3 times ULN
  * Adequate renal function as demonstrated by serum creatinine \<or= 1.5 mg/dL (\< 133 µmol/L) or calculated creatinine clearance ≥50 mL/min
  * Controlled blood pressure (\<140/90 mm Hg) with or without antihypertensive treatment
  * Prothrombin time (PT) with an international normalized ratio (INR) \<or=1.2
  * Partial thromboplastin time (PTT) \<or= 1.2 times ULN
  * Adequate cardiac function assessed by 12-lead ECG and if clinically indicated echocardiography to document LVEF
  * FDG-PET/CT performed
  * DCE MRI and DWI MRI performed
* Primary tumor ≥2 cm in their largest diameter measured bidimensionally by imaging done within 2 weeks prior to randomization
* Availability of tumor and normal mucosa biopsies during staging endoscopy (please refer to surgical guidelines for further information).
* Availability of blood samples for translational research
* Absence of any serious underlying medical conditions which could impair the ability of the patient to participate in the study
* Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and 6 months beyond stop of treatment in such a manner that the risk of pregnancy is minimized. In general, the decision for appropriate methods to prevent pregnancy should be determined by discussions between the investigator and the study subject. WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal. Females should not be breast feeding.

  * Post menopause is defined as: amenorrhea ≥ 12 consecutive months without another cause or for women with irregular menstrual periods and on hormone replacement therapy (HRT), a documented serum follicle stimulating hormone (FSH) level \> 35 mIU/mL
  * Women who are using oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicide) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (e.g., vasectomy) should be considered to be of childbearing potential.
  * Women of child bearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of investigational product.
  * Female patients within one year of entering the menopause must agree to use an effective non-hormonal method of contraception during the treatment period and for at least 6 months after the last study treatment.
* Males must agree to use an effective method of contraception during the treatment period and for at least 6 months after the last study treatment.
* Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
* Before patient registration, written informed consent must be given according to ICH/GCP, and national/local regulations

Exclusion Criteria:

* Patients with nasopharynx, nasal cavity and paranasal sinuses carcinomas, or recurrent/metastatic SCCHN are not eligible for this study
* T3 -T4 hypopharyngeal SCCHN are excluded.
* Distant metastases
* Active second malignancy during the last five years except non melanomatous skin cancer or carcinoma in situ of the cervix
* Prior chemotherapy, radiotherapy or targeted therapy including HER inhibitors (monoclonal antibodies or tyrosine kinase inhibitors) for SCCHN
* Concomitant use of potent P-gp inhibitors, potent P-gp inducers or Erythropoietin (EPO)
* Evidence of diabetes
* Evidence of interstitial lung disease
* Weight loss of more than 10% in the previous 6 months
* Participation in another interventional clinical trial in the preceding 30 days prior to randomization
