EURTACPhase III, Multicenter, Open-label, Randomized Trial of Tarceva® vs Chemotherapy in Patients With Advanced NSCLC With Mutations in the TK Domain of the EGFR

Study start date: February 15, 2007

Inclusion criteria: * Informed consent * Histologically confirmed diagnosis of NSCLC, non epidermoid, stage IV or IIIB with pleural effusion, or N3 tumours not candidate for thoracic radiotherapy, harbouring deletions in the exon 19 or mutation in the exon 21 in the TK of the EGFR. * Either measurable or evaluable disease. * Age \> 18 years. * ECOG performance status \< 2. * Adequate bone marrow function * Adequate renal function * Adequate hepatic function * Patients must be accessible for treatment and follow-up. * Patients capable of following an adequate therapeutic compliance * Women of child bearing potential: negative pregnancy test. * Patients of both genders at a fertile age, including those women having their last menstruation within the two previous years, must follow effective contraceptive measures. * Ability to swallow. * Patients with asymptomatic brain metastasis and stable with medical treatment will be eligible for the study. Patients having received radiotherapy for their brain metastasis prior to the systemic treatment for the NSCLC will be also eligible. * Absence of gastrointestinal tract problems Exclusion criteria: * Pregnant or lactating women. * Women of child bearing potential having a positive pregnancy test in the basal visit or not accomplishing the test. * Patients of both genders sexually active (at a fertile age) not following contraceptive measures during the study. * Prior chemotherapy for metastatic disease. Both prior neoadjuvant and adjuvant chemotherapy allowed provided that completed ≥ 6 months before entering the study. * Prior treatment with EGFR targeted therapies. * Patients may have received radiotherapy, provided that the irradiated lesion is not the only evaluable lesion for response and completed before entering the study. * Prior experimental pharmacological agent within the 3 weeks prior to the inclusion of the study. * Any significant ophthalmologic impairment of the eye surface. Use of contact lenses is not recommended. * Pre-existing motor or sensorial neurotoxicity grade \> 2, according to the NCI-CTC criteria. * Evidence of spinal cord compression. * Inability to take oral medication and surgical procedures affecting the absorption or implying intravenous or parenteral feeding. * Any other severe disease or clinical conditions, as, but not only: * Unstable cardiopathy despite treatment, myocardial infarction within the 6 months before entering the study * History of significant neurological or psychiatric disorders, including dementia and epileptic seizures. * Uncontrolled active infection. * Uncontrolled peptic ulcer. * Unstable diabetes mellitus or any other contraindication for treatment with corticosteroids. * AST and/or ALT \> 1.5 x UNL associated to alkaline phosphatase \> 2.5 x UNL. * Any other underlying severe process affecting the ability to take part in the study. * Absolute contraindication for steroids. * Dementia or significant mental disorder interfering the understanding and giving the informed consent. * History of other malignancy except adequately treated basal cell or squamous cell skin cancer, carcinoma in situ of the cervix, radically treated prostatic carcinoma with good prognostic (Gleason = 6). History of other curatively treated malignancy and no evidence of disease within the past 5 years.
