E.5 End points |
E.5.1 | Primary end point(s) |
• The quantitative uptake of 89Zr-AMG211 in tumor tissue, organs and blood circulation expressed in SUV (Standardized Uptake Value)
89Zr-AMG211 tumor uptake and organ distribution will be scored visually and quantitatively.
Standardized uptake value (SUV), relative uptake value (RUV) and %ID (percentage of injected dose) of 89Zr will be determined in the tumor lesions and in relevant tissues. These calculations will provide information on 89Zr-AMG211 penetration in gastrointestinal adenocarcinoma and the organ distribution.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
During the study we will continously monitor the obtained results. To evaluate the primary endpoint all data will be analysed when the study is ended. |
|
E.5.2 | Secondary end point(s) |
• Response to AMG 211 therapy will be analyzed in Study 20130354 according to the immune related response criteria (irRC). These results will be correlated to 89Zr-AMG211 tumor uptake data (measured in SUV).
• Number of patients with adverse events after 89Zr-AMG211 injection as a measure of safety and tolerability. Incidence, nature and severity of adverse
events will be measured.
