Phase 3, Open-Label, Multicenter Safety Study of Oral Edaravone in Patients With Amyotrophic Lateral Sclerosis (MT-1186-A01): 48-Week Results (P6-4.001)
Bibliographic record
Abstract
Objective: Study MT-1186-A01 assessed the safety and tolerability of oral edaravone (MT-1186) in patients with ALS. NCT04165824. Background: An intravenous (IV) formulation of edaravone (Radicava®/Radicut) has been shown to slow the rate of physical functional decline in amyotrophic lateral sclerosis (ALS). Radicava ORS® (edaravone) oral suspension was recently approved by the US Food and Drug Administration for use in patients with ALS. Design/Methods: Study MT-1186-A01 was a global, multicenter, open-label, phase 3 study that evaluated the long-term safety and tolerability of oral edaravone in patients with ALS. The primary safety analysis was assessed at weeks 24 and 48. Patients received a 105-mg dose of oral edaravone administered in treatment cycles that replicated IV edaravone dosing. Results: In the safety analysis population (n=185), the most common treatment-emergent adverse events (TEAEs) reported by ≥5% of patients were fall (22.2%), muscular weakness (21.1%), constipation (17.8%), dyspnea (10.8%), dysphagia (10.3%), and back pain (10.3%). TEAEs considered to be study drug-related were reported by 46/185 (24.9%) patients, with the most common being fatigue (3.2%), dizziness (2.7%), headache (2.2%), and constipation (2.2%). Serious TEAEs were reported by 48/185 (25.9%) patients, with the most common being worsening of ALS symptoms (6.5%), dysphagia (3.2%), dyspnea (2.7%), and respiratory failure (2.7%). TEAEs leading to death were reported in 12/185 (6.5%) patients, including respiratory failure (2.2%), worsening of ALS (1.1%), pneumonia (1.1%), acute respiratory failure (0.5%), lung disorder (0.5%), diabetic ketoacidosis (0.5%), feeding disorder (0.5%), and suicide (0.5%). TEAEs leading to discontinuation were reported by 2/185 patients (tremor, n=1; gait disturbance, n=1); both TEAEs considered by the investigator to be study drug-related. No serious TEAEs, or TEAEs leading to death, were study drug-related. Conclusions: This study demonstrates that oral edaravone was generally safe and well tolerated during 48 weeks of treatment, with no new safety concerns identified.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
