Clinical Trial Summary

The objective is to compare the efficacy and safety of masitinib in combination with riluzole versus matched placebo in combination with riluzole for the treatment of Amyotrophic Lateral Sclerosis (ALS).

Description:

Masitinib is a selective, oral tyrosine kinase inhibitor with neuroprotective capability demonstrated via numerous preclinical studies. Two of masitinib's main cellular targets are the mast cell and microglia cell. It is well-established that mast cells play a prominent role in neuroinflammatory processes. Microglia, resident immune cells of the central nervous system (CNS), also constitute an important source of neuroinflammatory mediators and may have fundamental roles in numerous neurodegenerative disorders. The development of masitinib in ALS is therefore based on the pharmacological action of masitinib in microglia cells and mast cells, thereby slowing microglial-related disease progression, reducing neuro-inflammation, and modulating the neuronal microenvironment in both central and peripheral nervous systems. This is a multicenter, double-blind, randomized, placebo-controlled, parallel-group (two ascending dose titrations of masitinib and matching placebo), comparative study of oral masitinib in the treatment of patients with amyotrophic lateral sclerosis (ALS).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	ALSFRS-R	Change in Amyotrophic Lateral Sclerosis functional rating scale (ALSFRS)-Revised.	48 weeks
Secondary	ALSAQ-40	Change in ALS quality of life patient questionnaire (ALSAQ-40)	48 weeks
Secondary	PFS	Progression free survival (PFS) is defined as the time from randomization to progression (decline of more than 9 points in ALSFRS-R score from baseline) or death	From day of randomization to disease progression or death, assessed for a maximum of 36 months
Secondary	FVC	Change in Forced Vital Capacity (FVC)	48 weeks
Secondary	HHD	Change in evaluation of upper- and lower-limb muscle strength using hand-held dynamometry (HHD)	48 weeks
Secondary	Change in the Combined Assessment of Function and Survival (CAFS) score from baseline to week 48	CAFS ranks patients' clinical outcomes based on survival time and change in the ALS Functional Rating Scale-Revised (ALSFRS-R) score. Each patient's outcome is compared to every other patient's outcome, assigned a score, and the summed scores are ranked. The mean rank score for each treatment group can then be calculated. A higher mean CAFS score indicates a better group outcome.	48 weeks
