Observational Study of Afatinib 30 mg Daily

This is a multi-country, multi-centre, study designed to collect clinical data and to evaluate efficacy and safety of patients treated with afatinib 30 mg at the Investigator's discretion. All entered patients (i.e., patients that have been treated with the defined medication) will receive continuous treatment of afatinib in the absence of disease progression or meeting any other withdrawal criteria. All patients will visit Investigator at regular intervals for assessment of efficacy and safety as outlined in the Flow Chart for the first 7 cycles treatment. The Investigator will assess the patient at each visit. Tumour response and progression will be assessed using RECIST 1.1 at the Investigator site.
