Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Measurement of Epidermal Growth Factor Receptor-EGFR-specific T cells (The method is based on the ELISPOT test. The technique measures secretion of cytokines related to the activation of cytotoxic T lymphocytes following stimulation of peripheral blood mononuclear cells with peptides derived from the antigen). Measurement time: 12 months.<br>Overall survival (Time from recruitment until death from any cause). Measurement time: 3, 6, 9 and 12 months.

Secondary Outcome Measures

Name	Time	Method
Response to treatment <br>Objective response (measured by RECIST criteria according to Complete Response, Partial Response, Stable Disease, Progression). Measurement time: at baseline, 3, 6, 9 and 12 months.<br>Related to Safety<br>Adverse Events-AE (Type of AE (AE description), Intensity of AE (Light, Moderate, Severe, Very Severe, Event related Death), Causality relationship (Very likely, Probable, Possible, Unlikely, Uncontrolled, Unclassifiable), Applied Treatment (None, Medication, Surgical Procedure, Transfusion, Other), Event Result (Recovered, Continued, Unknown, Death due to event)). Measurement time: at baseline, 3, 6, 9 and 12 months.
