Analysis of Long-Term Function and Survival of Edaravone Oral Suspension-Treated Patients With Amyotrophic Lateral Sclerosis Using PRO-ACT Data as Historical Placebo Controls.
Introduction/aims: On/Off dosing of intravenous (IV) edaravone and edaravone oral suspension was US Food and Drug Administration (FDA)-approved for Amyotrophic Lateral Sclerosis (ALS) treatment. Placebo-controlled trials showed that IV edaravone slows the rate of physical functional decline in patients with ALS. Here, the impact of edaravone oral suspension on function and survival was assessed.
Methods: Edaravone oral suspension was investigated in clinical trials MT-1186-A01/A02/A03/A04. Patients from Studies MT-1186-A02/A04 (prespecified analysis) and Studies MT-1186-A01/A02/A03/A04 (post hoc analysis) were propensity score matched 1:1 on 10 baseline variables with historical Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) placebo patients (not receiving active investigational treatment in their trials) to assess the impact of edaravone oral suspension on function and survival.
Results: In the prespecified analysis, 78 edaravone oral suspension-treated patients from Studies MT-1186-A02/A04 demonstrated a survival benefit versus 78 matched PRO-ACT placebo patients (p = 0.005). Baseline risk-adjusted hazard ratio showed an 84% decreased risk of death in edaravone oral suspension versus PRO-ACT placebo patients (p = 0.005). ALS Functional Rating Scale-Revised (ALSFRS-R) total score change from baseline at Week 48 was -8.4 points for edaravone oral suspension versus -14.1 points for PRO-ACT placebo patients (p < 0.001). In the post hoc analysis, patients from Studies MT-1186-A01/A02/A03/A04 (n = 210) propensity score matched to PRO-ACT placebo patients (n = 210) showed statistically significantly longer time to death and smaller ALSFRS-R change from baseline at Week 48; restricted mean survival time showed a 7.3-month improvement (p < 0.001).
Discussion: This suggests edaravone oral suspension significantly increases survival time and decreases physical functional decline versus PRO-ACT placebo patients.
期刊介绍：
Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified. Appearing monthly, Muscle & Nerve publishes clinical studies and clinically relevant research reports in the fields of anatomy, biochemistry, cell biology, electrophysiology and electrodiagnosis, epidemiology, genetics, immunology, pathology, pharmacology, physiology, toxicology, and virology. The Journal welcomes articles and reports on basic clinical electrophysiology and electrodiagnosis. We expedite some papers dealing with timely topics to keep up with the fast-moving pace of science, based on the referees'' recommendation.
