简要总结
The study evaluates the effects of two different Colchicine doses (0.01mg/kg/day or 0.005 mg/kg/day) compared to placebo in Amyotrophic Lateral Sclerosis (ALS) patients. Disease progression as defined by changes in ALSFRS-r is the primary outcome measure. Other measures of clinical progression and survival, together with safety and tolerability of Colchicine in ALS patients will be assessed.
详细描述
Recent evidence supports the disruption of the ubiquitin-proteasome-system and autophagy as central events in ALS. ALS is characterized by the presence of misfolded proteins prone to oligomerize into aggregates, which exert a toxic effect by affecting several intracellular functions. Heat shock protein B8 (HSPB8) recognizes and promotes the autophagy-mediated removal of misfolded mutant SOD1 and TDP-43 fragments from ALS motor neurons (MNs). Moreover, HSPB8-BAG3-HSP70 maintains the so called "granulostasis", a surveillance mechanism that avoids the conversion of dynamic stress granules (SGs) into aggregation-prone assemblies, which are a hallmark of ALS.
Colchicine enhances the expression of HSPB8 and of several autophagy players while blocking TDP-43 accumulation in neurons. Moreover, given the cross-talk between infalmmation and autophagy, the well-known antinflammatory action of Cochicine may contribute to cell homeostasis.
Based on these premises, this is a phase II randomized, double-blind, placebo-controlled, multicenter (9 MND Centres in Italy: 2 centres in Milan, Pavia, Turin, Modena, Padua, Rome, Naples, Bari), clinical trial to test efficacy of Colchicine in ALS.

结局指标
主要结局
Decrease in ALS disease progression as measured by ALS Functional rating Scale Revised (ALSFRS-R)
时间窗: comparison between baseline and treatment end (week 30)
ALSFRS-R is a scale that measures disability in ALS; the scores range from 0 (maximum disability, the worst score) to 48 (no disability, the best score). We will measure total score changes from baseline to week 30 in treatment and placebo arms.
次要结局
- Incidence of Treatment-Emergent Adverse Events (safety and tolerability)(week 30 and 54)
- enhancement of autophagy(at week 30 and 54, compared to baseline)
- Tracheostomy-free survival rate(Up to week 54)
- Changes in Forced Vital Capacity (FVC)(Up to week 54)
- quantification of insoluble species(at week 30 compared to baseline)
- effects on biomarkers of inflammation(at week 30 compared to baseline)
- effects on biomarkers of neurodegeneration(at week 30 compared to baseline)
- changes in stress granules size, number and composition(at week 30 compared to baseline)
- modifications on extracellular vesicles secretion in blood and CSF(at week 30 compared to baseline)
- Changes in quality of life(at 8,18,30 and 54 week)
