Severe adverse events (Appearance of severe adverse events (Yes, No). Measuring time: at each administration during the 8 weeks of treatment.
- Secondary Outcome Measures
Name Time Method Complete closure of the lesion (defined by the epithelization and total closure of the lesion without secretion or dressing application). Measuring time: before treatment, and weeks 4, 8, 12, 16 and 20. One-hundred percent of soft granulation tissue. Measuring time: before treatment, and weeks 4, 8, 12, 16 and 20. Clinical adverse events (AE). Measuring time: at each administration during 8 weeks of treatment -Appearance of AE (Yes, No) -Type of AE (name of the AE) -Duration (time between beginning and end of the event), -Intensity of AE (mild, moderate, severe) -Relation of causality (remote, possible, probable, very probable) -Result of AE (recuperate, improvement, persist or sequels), attitude concerning the studied treatment (without changes, dose modification, temporal or definitive treatment discontinuation). Anti-EGF antibodies (by ELISA technique. Patients that develop antibodies (Yes, No)). Measuring time: before treatment, week 8 and week 20.
