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):

Clinical response (will be evaluated taking into account the severity of the infection according to the Criteria of the American Society of Infectious Diseases -IDSA- in the categories of: non-infected, mild, moderate and severe. A satisfactory clinical response will be considered when the lesion is in the non-infected category, that is, it does not present any signs or clinical symptoms of infection such as inflammation, induration, sensitivity, edema, redness, erythema, pain, local heat and purulent discharge). Measurement time: before starting treatment with Dermofural®/placebo and 48 hours after finishing it. Microbiological response (The presence or absence of bacterial growth in the samples taken from closed abscesses or secretions in the diabetic foot ulcer will be determined. Microbiological culture and antibiogram will be performed). Measurement time: before starting treatment with Dermofural®/placebo and 48 hours after finishing it. Global response (combination of clinical and microbiological response). It will be evaluated in the categories "Satisfactory" and "Unsatisfactory" where: - Satisfactory: when 48 hours after the last application of the assigned treatment, the clinical response of the lesion is in the non-infected category (no presence of any clinical signs and symptoms: inflammation, induration, tenderness, edema , redness, erythema, pain, local heat, hyperesthesia and purulent discharge) and present microbiological response (absence of bacterial growth in the DFU or healed ulcer). - Unsatisfactory: when 48 hours after the last application of the assigned treatment, the clinical response of the lesion is in the mild, moderate or severe categories and there is no microbiological response (there is bacterial growth in the DFU) or presents satisfactory clinical response (absence of clinical signs and symptoms) without microbiological response (there is bacterial growth).

Key secondary outcomes:

Safety (identification of adverse events occurring during the application of the test product). Measuring time: daily, during 7 days.. Occurrence (yes/no), Description (EA presented is reported using an accurate medical terminology), Duration (date difference between the beginning and the end of the event), Intensity (mild, moderate or severe), Seriousness (serious/serious or not serious/not serious), Attitude toward the drug (unchanged or permanent discontinuation), Results (recovered, improved persists, worsens, death), Causation (likely/certain, probable, possible, unlikely, unrelated or not evaluable/unclassifiable), Local events (yes/no), Systemic events (yes/no). -Biochemical parameters (Hemoglobin g/L, total leukocyte count cells/L, neutrophils %, lymphocytes %, monocytes %, eosinophils %, basophils %, platelet count cells/L, erythro mm/h, creatinine mmol/L, TGO U/L, TGP U/L). Measuring time: before starting treatment with Dermofural®/placebo and after finishing it. (Glucose mmol/L). Measuring time: daily, for 7 days (or Glycosylated hemoglobin %). Measuring time: before starting treatment with Dermofural®/placebo.
