Eligibility Criteria:
Inclusion criteria:~* Histologically or cytologically confirmed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx, which has recurred/metastasised and is not amenable for salvage surgery or radiotherapy.~* Documented progressive disease based on investigator assessment according to RECIST, following receipt of a cisplatin and/or carboplatin and/or Nedaplatin based regimen administered for recurrent and/or metastatic disease independent of whether patient progressed during or after platinum based therapy.~* Measurable disease according to RECIST (version 1.1).~* Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 at Visit 2.~* Male and female patients age is 18 years or older~* Signed and dated written informed consent that is in compliance with ICH-GCP and local law.~Exclusion criteria:~* Progressive disease within three months after completion of curatively intended treatment for locoregionally advanced or for metastatic head and neck squamous cell cancer (HNSCC).~* Primary tumour site nasopharynx (of any histology), sinuses, and/or salivary glands.~* Any other than one previous platinum based systemic regimen given for recurrent and/or metastatic disease, with the exception of immunotherapy used either before or after platinum based treatment. Re-challenge with the platinum based regimen after a temporary break is considered an additional line regimen only in case of progression within the break.~* Prior treatment with EGFR-targeted small molecules.~* Treatment with any investigational drug less than four weeks or anti-cancer therapy less than three weeks prior to randomization (except palliative radiotherapy to bones to alleviate pain).~* Unresolved chronic toxicity, other than hearing loss, tinnitus or dry mouth, CTCAE grade \>2 from previous anti-cancer therapy or unresolved skin toxicities CTCAE grade \>1 and/or diarrhoea CTCAE grade \>1 caused by prior treatment with EGFR targeted antibodies.~* Previous tumour bleeding CTCAE grade =3.~* Requirement for treatment with any of the prohibited concomitant medications.~* Major surgical or planned procedure less than four weeks prior to randomization (isolated biopsies are not considered as major surgical procedures).~* Any other malignancy unless free of disease for at least five years except for:~  * Other HNSCC of a location as described in inclusion criterion number 1~ * Appropriately treated superficial basal cell skin cancer~ * Surgically cured cervical cancer in situ~ * For Korea: endoscopically cured superficial esophageal and/or gastric cancer is allowed~* Known lesion or signs of brain metastasis.~* Known pre-existing interstitial lung disease (ILD).~* Clinically relevant cardiovascular abnormalities, as judged by the investigator, such as, but not limited to, uncontrolled hypertension, congestive heart failure NYHA classification =III, unstable angina, myocardial infarction within six months prior to randomization, or poorly controlled arrhythmia.~* Significant or recent acute gastrointestinal disorders with diarrhoea as a major symptom in the opinion of the investigator, e.g. Crohn's disease, malabsorption or CTCAE grade \>1 diarrhoea of any aetiology at randomization.~* Known HIV, active hepatitis B, active hepatitis C, and/or other known severe infections, including but not limited to tuberculosis, as judged by the investigator.~* Other significant disease that in the investigator's opinion would exclude the subject from the trial.~* Screening laboratory values:~  * Absolute neutrophil count (ANC) \<1.5x10\^9/l~ * Platelet count \<75x10\^9/l~ * Total bilirubin \>1.5 times the upper limit of normal (ULN)~ * Aspartate amino transferase (AST) or alanine amino transferase (ALT) \>3 times the ULN (if related to liver metastases \>5 times the ULN)~ * Calculated creatinine clearance \<50 ml/min (as evidenced by using the Cockcroft-Gault formula).~* Women of child-bearing potential and men who are able to father a child, unwilling to be abstinent or to use adequate contraception during the trial and for at least six months after end of treatment. Adequate methods of contraception and definition of child-bearing potential.~* Pregnancy or breast feeding.~* Known or suspected hypersensitivity to any of the study medications or their excipients.~* Patients unable to comply with the protocol, in the opinion of the investigator.
