目前主要观察指标 ^ICMJE

Decrease in ALS disease progression as measured by ALS Functional rating Scale Revised (ALSFRS-R)[ Time Frame: 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.

changes in stress granules size, number and composition[ Time Frame: at week 30 compared to baseline ]
identification of changes in stress granules response and composition in patients' fibroblasts and lymphoblasts will be carried out by measuring granules size, number and composition by confocal microscopy using automated systems. The aberrant recruitment or sequestration of specific mRNA inside stress granules will be assessed by FISH using specific probes, followed by densitometric analysis as previously described by Gareau et al. (2011).
quantification of insoluble species[ Time Frame: at week 30 compared to baseline ]
assessment of overall levels and the relative ratio between soluble and insoluble species of TDP-43, TDP-43 fragments, SQSTM1/p62, UBQLN, OPTN in fibroblasts and lymphoblasts derived from the same patients

effects on biomarkers of neurodegeneration[ Time Frame: at week 30 compared to baseline ]
creatinine, albumin, CK, and vitamin D in plasma as markers of disease severity; phosphorylated neurofilaments heavy chain
effects on biomarkers of inflammation[ Time Frame: at week 30 compared to baseline ]
assessment of plasma/CSF IL18, its endogenous inhibitor IL-18BP, MCP1 and IL17

Colchicine for Amyotrophic Lateral Sclerosis: a Phase II, Randomized, Double Blind, Placebo Controlled, Multicenter Clinical Trial

简要概况

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.

详细说明

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.
