This non-randomized, open-label, outpatient clinical trial is designed to assess the safety and efficacy of daily orally administered EKB-569 in subjects with advanced colorectal cancer. Patients must have been previously treated with a fluoropyrimidine (5-FU or capecitabine) and either oxaliplatin or irinotecan (given concurrently or as separate regimens). The primary objective of the study is to assess the clinical activity of EKB-569 administered orally as a second-line or later stage treatment in subjects with advanced colorectal cancer. Secondary objectives include: * To further evaluate the safety of EKB-569 * To explore additional clinical activity parameters * To explore subject survival * To evaluate the pharmacokinetics of EKB-569 * To assess subject reported outcomes EKB-569 will be administered orally as a single-agent. Eligible subjects will take EKB-569 daily as long as they do not have progressive disease and are tolerating treatment.
