Masitinib may delay disability progression in multiple sclerosis
Spain: In a new study, it was found that masitinib 4.5 mg/kg/d reduced disability progression in individuals with patients with primary progressive multiple sclerosis (PPMS) or patients with inactive secondary progressive MS (nSPMS). The findings of this study were published in the journal Neurology: Neuroimmunology & Neuroinflammation.
Masitinib is a tyrosine kinase inhibitor that targets innate immune cells (mast cells and microglia) in the pathogenesis of progressive multiple sclerosis. As a result, Patrick Vermersch and colleagues undertook this trial to evaluate oral masitinib in individuals with progressive multiple sclerosis who were advancing but not clinically active.
This 116 hospital clinics and specialist MS facilities in 20 countries double-blind, randomized, placebo-controlled, two-parallel-group experiment compared two dosage levels of masitinib against an equal placebo. An automated technique was used to produce central randomization (2:1) with minimization. physicians, patients, and outcome assessors were all kept in the dark about which therapy group they were in, nSPMS or PPMS who had not relapsed for 2 years, were aged 18–75 years, had a baseline Expanded Disability Status Scale (EDSS) of 2.0–6.0, and were treated for 96 weeks, independent of time from start. The primary endpoint was the change in total EDSS from baseline using repeated assessments, with positive values suggesting more clinical deterioration. All patients who were randomly assigned and treated were evaluated for efficacy and safety.
The key findings of this study were as follow:
1. A total of 611 patients were randomly assigned to one of two groups: 301 in the 4.5 mg/kg/d parallel-group and 310 in the up titrated 6.0 mg/kg/d parallel group.
2. Masitinib (4.5 mg/kg/d) (n = 199) outperformed placebo (n = 101) in terms of the primary end goal, 0.001 vs 0.098, with a between-group difference of 0.097.
3. Masitinib's safety profile was constant (nausea, diarrhea, hematologic problems, and rash), with no increased risk of infection.
4. The independent up titrated masitinib 6.0 mg/kg/d parallel group's efficacy findings were unclear, and no new safety signal was found.
In conclusion, the study provides Class II evidence that masitinib at 4.5 mg/kg/d decreased progression of disability, measured by the EDSS, in adults with PPMS or patients with nSPMS (with no exacerbations in the last 2 years); however, there is a need for further validation of these findings via a confirmatory phase 3 study, in part because neuroimaging data were not collected during the current study and also due to a lack of signal on secondary endpoints.
This study provides Class II evidence that masitinib 4.5 mg/kg/d decreased progression of disability, measured by the EDSS, in adults with PPMS or patients with nSPMS (with no exacerbations in the last 2 years).
