The trial will be performed in a community practice setting, with approximately 230 centers participating in the trial worldwide (planned countries are Argentina, Australia, Austria, Belgium, Brazil, Chile, China, Colombia, Czech Republic, France, Germany, Greece, Hong Kong, Hungary, India, Ireland, Israel, Italy, Mexico, Netherlands, Poland, Portugal, Russia, Singapore, Slovakia, South Africa, South Korea, Spain, Switzerland, Taiwan, Turkey, United Kingdom and Venezuela). With noncompetitive enrollment, approximately 4 to 8 subjects are expected to be enrolled at each center. Enrollment in the individual centers is generally limited to a maximum of 8 subjects. If any of these subjects does not receive trial treatment for any reason or discontinue all trial treatment at the first visit, additional subjects may be enrolled until 8 subjects were treated. The primary endpoint of the trial will be overall survival time from inclusion into the trial to death. Additional secondary efficacy endpoints will be time to treatment failure, tumor response, and disease control rate. Other endpoints will include safety and toxicity, compliance with maintenance therapy, subject satisfaction and translational research (TR) (for subjects with tumor samples available).
