Primary Outcome Measures

Name	Time	Method
Main Objective: To evaluate the activity and efficacy of panitumumab in metastatic or locally advanced well differentiated neuroendocrine tumor after somatostatine analogues and possible chemotherapy.;Secondary Objective: To evaluate activity (on further parameters: see §2.4), efficacy and tolerability of panitumumab in metastatic or locally advanced well differentiated neuroendocrine tumor after somatostatine analogues and chemotherapy.;Primary end point(s): Activity is defined as Non-progression rate, (RECIST criteria version 1.1), as evaluated at 6 months.;Timepoint(s) of evaluation of this end point: 6 months

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): Best objective response (CR + PR according to RECIST criteria version 1.1): complete plus partial responses, as evaluated at 6 months Biochemical response (changes of tumor marker values) Time to progression (TTP) and overall survival (OS), as estimated by the Kaplan-Meier method. Adverse reaction definition and grading according to CTC-AE v.3.0;Timepoint(s) of evaluation of this end point: 24 months
