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):

Serious Adverse Events (SAE). They will be measured as: -SAE occurrence (Yes, No), -SAE description (name of the event), -Causality relationship (probable or definitive), -Measures taken (None, Administration of any pharmacological therapy, Addition of a therapy Non-pharmacological, Exit from the study, Hospitalization / prolongation of hospitalization), -Result (Completely resolved, Resolved with sequelae, Conditions in improvement, Condition present and unchanged, Worsening, Death caused by this event). Measurement time: three times a week for 8 weeks.

Key secondary outcomes:

Clinical response: a) Criteria of the patient about his pain (reduction or not of the parameter, in number, through the Brief Inventory of pain scale, and the MICHIGAN scale). Measurement time: on inclusion, weekly for 8 weeks. b) Pain response criteria (percentage of pain reduction according to the Mc Gill pain questionnaire). Measurement time: at inclusion, weekly for 8 weeks; c) Drug reduction criteria for neuropathic pain (number of drugs administered for pain); Measurement time: at inclusion, weekly for 8 weeks; d) motor and sensory neuroconduction of the sural and peroneal nerves (distal latency, amplitude, conduction velocity). Measurement time: on inclusion, weekly for 8 weeks. Pharmacokinetic evaluation: Pharmacokinetic profile (Area under the curve, Plasma clearance, Apparent volume of distribution at steady state, Average lifetime, Average residence time). Measurement time: After administration of the FCEhr in its first dose. Adverse clinical events not related to research products (AE). They will be measured as: - AE occurrence (Yes, No), - AE description (event name), - Intensity of the AE (mild, moderate, severe), - Causality ratio (not related, doubtful, possible), - Measures taken (None, Administration of any pharmacological therapy, Addition of a non-pharmacological therapy, Exit from the study, Hospitalization / prolongation of hospitalization), -Result (Completely resolved, Resolved with sequelae, Conditions in improvement, Condition present and invariant, Worsening , Death caused by this event). Measurement time: three times a week for 8 weeks.
