Patients will take both drugs orally, every day, without planned rest period (AX bid and EV once a day). By convention one cycle is 28 days. At the first cycle patients will take one week of AX single agent before starting EV. Patients will be treated at increasing dose levels (DLs) in successive cohorts of 3-6 patients according to the number of patients with dose limiting toxicities (DLT) until the maximum tolerated dose (MTD; i.e. the DL at which <= 1/6 patient experiences a DLT during the first cycle). All decision concerning qualification for DLT, dose escalation, study termination, inclusion of additional patients, will be taken by a Trial Monitoring Committee..
