Design outcomes

Primary

MeasureTime frame
Main Objective: The primary goal of the trial is to show that treatment with plasma exchange plus therapeutic albumin replacement in patients with AMN induces a decrease of plasma and cerebrospinal fluid VLCFA.;Secondary Objective: The secondary goal of the trial is the assessment of efficacy and safety of the proposed treatment in 5 patients with AMN. Efficacy will be measured in terms of motor function and quality of life. Only in case of a decrease in VLCFA other biological markers (oxidation and inflammation biomarkers) will also be studied. Safety will be evaluated by clinical and biochemical exams and recording of any adverse event.;Primary end point(s): The main efficacy evaluation criterion is changes in plasma VLCFA between M0 and M6. C26:0, C24:0 and C26:0/C22:0 will be measured in plasma.;Timepoint(s) of evaluation of this end point: The assessment of the main variable is in month 6.

Secondary

MeasureTime frame
Secondary end point(s): Efficacy endpoints: 1) Tests evaluating the motor functions of treated AMN patients. They include: the Timed Up and Go (TUG) test, the Time to walk 25 feet (TW25), the 2 minute walk test (2MWT) and the 6 minute walk test (6MWT) on M0, M6 and M12. 2) Quality of life: score of SF-Qualiveen on M0, M6 and M12. 3) VLCFA in CSF (optional): C26:0, C24:0 and C26:0/C22:0 will be measured in CSF in those patients with AMN who voluntarily accept to undergo a lumbar puncture on M0, M6 and M12. 4) Biological measures (only in case of a decrease in VLCFA): - Marker of oxidative stress: 8oxo-dG in urine. 8oxo-dG will be measured on M0, M6 and M12. - Markers of inflammation: CCR3, CXCL5, CXCL9, IL9R, PPARd, GPX4 and STAT1 in RNA obtained from MNC and HGF, IL6, IL8, MCP-1, NGF, TNF and adiponectin in plasma will be measured on M0, M6 and M12. Safety endpoints: Safety will be evaluated by clinical and biochemical exams and recording of any adverse event.;Timepoint(s) of evaluation of this end point: The assessment of the secondary endpoints are in month 0, 6 i 12 (M0, M6, M12)
