Trial Summary

Do I have to stop taking my current medications for the trial?

The trial requires participants to be on a stable dose of riluzole (100 mg/day) for at least 12 weeks before starting. The protocol does not specify if you need to stop other medications, so it's best to discuss with the trial team.

What data supports the effectiveness of the drug masitinib for ALS?

Research shows that masitinib, when added to the existing ALS drug riluzole, can slow the rate of functional decline in patients with ALS by 27% compared to a placebo. This suggests that masitinib may help improve the quality of life for ALS patients.12345

Is masitinib safe for humans?

Masitinib has been tested in people with ALS and showed an acceptable safety profile, although some patients experienced side effects like those seen with placebo. Serious side effects were slightly more common with masitinib than with placebo, but no deaths were linked to the drug.13456

How does the drug Masitinib for ALS differ from other treatments?

Masitinib is unique for ALS treatment because it is a tyrosine kinase inhibitor, which means it blocks certain enzymes that promote inflammation and cell growth, potentially slowing disease progression. This mechanism is different from Riluzole, the standard ALS treatment, which works by reducing damage to motor neurons.7891011

What is the purpose of this trial?

This trial tests if a new medication taken with riluzole can help ALS patients by reducing inflammation and protecting nerve cells. ALS patients are targeted because current treatments are not very effective.

Participant Groups
3Treatment groups
Experimental Treatment
Placebo Group
Group I: Masitinib (6.0) & RiluzoleExperimental Treatment2 Interventions
Participants receive masitinib (3.0 mg/kg/day), given orally twice daily, with a dose escalation to 4.5 mg/kg/day after 4 weeks of treatment, followed by dose escalation to 6.0 mg/kg/day after 4 weeks of treatment. Each ascending dose titration is subjected to a safety control. Masitinib will be administered as an add-on to riluzole at 50 mg b.i.d.
Group II: Masitinib (4.5) & RiluzoleExperimental Treatment2 Interventions
Participants receive masitinib (3.0 mg/kg/day), given orally twice daily, with a dose escalation to 4.5 mg/kg/day after 4 weeks of treatment. Each ascending dose titration is subjected to a safety control. Masitinib will be administered as an add-on to riluzole at 50 mg b.i.d
Group III: Placebo & RiluzolePlacebo Group2 Interventions
Participants receive a matched dose placebo, given orally twice daily, in combination with riluzole at 50 mg b.i.d.

Findings from Research

MN-166 (ibudilast) shows promise as a neuroprotective treatment for ALS by inhibiting inflammation and glial cell activation, with early studies indicating potential improvements in survival and disease progression.
The ongoing COMBAT-ALS study, involving a randomized, double-blind, placebo-controlled design, aims to rigorously evaluate the safety, tolerability, and efficacy of MN-166 on various outcomes in ALS patients.
MN-166 (ibudilast) in amyotrophic lateral sclerosis in a Phase IIb/III study: COMBAT-ALS study design.Oskarsson, B., Maragakis, N., Bedlack, RS., et al.[2022]
Riluzole is currently the only approved treatment for ALS, but its efficacy is mild, and despite extensive research, most clinical trials for new ALS treatments have not shown significant benefits.
Recent studies on oral masitinib and intravenous edaravone suggest they may be promising new therapies for ALS, with masitinib including a broader patient population in its trials compared to edaravone, which could impact their future use in treatment.
ALS Clinical Trials Review: 20 Years of Failure. Are We Any Closer to Registering a New Treatment?Petrov, D., Mansfield, C., Moussy, A., et al.[2022]
In a study of 153 ALS patients, riluzole was found to have an acceptable safety profile, with 50.3% experiencing adverse effects, primarily gastrointestinal issues, hepatotoxicity, and fatigue.
Riluzole's mechanism of action suggests it may also be beneficial for other neurodegenerative diseases related to glutamate excitotoxicity, warranting further investigation and monitoring for its use.
