Health condition and Intervention
Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).
Health condition(s) or Problem(s) studied:
Esofagus Pre malignan lesion
Intervention(s):
Nimotuzumab group (Experimental): Nimotuzumab plus Omeprazole. The Nimotuzumab be administered intravenously (antecubital vein), equivalent to 200 mg diluted in 250 mL of 0.9% saline solution (total volume of 290 ml), in a 2-hour infusion. It will be administered 6 doses, once every fifteen days, concomitantly with Omeprazole. The Omeprazole will be administered a dose of 40 mg/day, for 12 weeks, orally, divided into two doses of 20 mg before breakfast and dinner. Omeprazole group (Control): The Omeprazole will be administered a dose of 40 mg/day, for 12 weeks, orally, divided into two doses of 20 mg before breakfast and dinner. After 12 weeks, the patient will be evaluated. If the patient responses, the scheme will repeat again.
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):
Saffety: 1. Serious Adverse Events (SAE) with a causal relationship (Patients proportion with SAE according to the CTCAE v5.0 classification that have a causal relationship Very probable/ certain, Probable, Possible according to Cecmed regulation 45/2007). Measurement time: over 12 months Effect: 1. Reduction of the premalignant lesion of Barrett's Esophagus (Proportion of patients who reduce the lesion with respect to the baseline time using endoscopic images). Measurement time: at baseline, 12 weeks, 6 months and 12 months 2. Duration of the response (Time in which the response is maintained). Measurement time: 12 weeks, 6 months and 12 months
Key secondary outcomes:
1. Adverse Events-AEs (Type of AE (description of the AE); organ system (system to which it belongs according to the CTCAE v5.0 classification); Duration (Time from the start until finish the AE); Intensity ( Mild, moderate, Severe according to Cecmed regulation 45/2007); Outcome (Reversible effect, Irreversible effect, Loss of follow-up, Death (No change, Temporary interruption, Definitive interruption) and Causal relationship (Very probable/ certain, Probable, Possible, Improbable, Not related, Not evaluable/not classifiable according to Cecmed regulation 45/2007)). Measurement time: over 12 months. 2. Correlation of the response with prognostic factors such as EGFr expression, NLR, PLR inflammatory indices (values of each prognostic factor). Measurement time: At baseline, 12 weeks, 6 months and 12 months 3. Clinical Laboratory (Values of: Hemoglobin, Total Leukocytes, Neutrophils, Lymphocytes, Platelets, Erythrocyte sedimentation rate, Amino-Aspartate Transferase, Glutamic Pyruvic Transferase, GGT, Cholesterol). Measurement time: At baseline, 12 weeks, 6 months and 12 months
