Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

1. Progression-free survival (Time from randomization until date of disease progression or death from any cause). Measurement time: every 3 months, for a period of 3 years, measured from the patient's inclusion in the trial. 2. Adverse Events- AE (Occurrence of any AE (Yes, No), Type of AE (It will be classified according to the classification established by the CTC (Common Toxicity Criteria) version 5.0 of the US National Cancer Institute), Duration of the AE (Time from the onset and the end of the adverse event), Intensity of the AE (It will be assessed according to the criteria established by the CTC (Common Toxicity Criteria) version 5.0 of the US National Cancer Institute as 1. Mild, 2. Moderate, and 3. Severe), Causal relationship (1. Definite, 2. Very probable, 3. Probable, 4. Possible, 5. Unrelated, 6. Unknown), Severity (Severe/serious, Non-serious/non-serious), Treatment response (1. No change, 2. Dose modification, 3. Temporary interruption, or 4. Permanent discontinuation), Outcome of the AE (1. Recovered, 2. Improved, 3. Persistent, or 4. Sequelae.)). Measurement time: from randomization until 3 years.

Key secondary outcomes:

1. Overall survival (Time measured from the date of inclusion in the study to the date of death. If the patient's death is uncertain, the time elapsed until the date the last patient update is recorded in the medical record will be recorded). Measurement time: From inclusion in the trial to death or last contact. 2. Objective response (RECIST 1.1 criteria, which subclassifies objective response into: a) complete response; b) partial remission; c) stable disease; and d) progressive disease). Measurement time: 3 months, 6 months, 12 months, 18 months, 24 months, and progression. 3. EGF-R expression. This refers to the tissue expression of the protein epidermal growth factor receptor, determined by immunohistochemical technique on formaldehyde-fixed, paraffin-embedded (FFEP) tissue blocks in tumor tissue from patients using colonoscopy. Scale: a) Negative, b) Positive +, c) Positive ++, and d) Positive +++. Measurement time: (D 0) before the start of treatment. 4. KRAS mutation status (Type of anomalous variant of the transcription factor KRAS, a protein responsible for the phosphorylation of several intracellular signal transduction pathways relevant to cancer, determined by molecular biology techniques from liquid biopsies obtained from peripheral blood and measured as a) Mutated, b) Not mutated). Measurement time: Before the start of treatment.
