Real-world safety and tolerability of intravenous edaravone in patients with amyotrophic lateral sclerosis
Bibliographic record
Abstract
Aims This retrospective cohort study describes real-world safety and tolerability outcomes in United States-based edaravone-treated patients with ALS.Patients & methods Amerita Specialty Infusion Services provided IV edaravone to patients with ALS treated with their first dose between 25 September 2017-30 September 2022. Mean ALS Functional Rating Scale-Revised (ALSFRS-R) scores and forced vital capacity (FVC) %–predicted measures were recorded within ± 100 days from care initiation to approximate baseline values.Results Included patients (n = 243) received/were still receiving IV edaravone/edaravone oral suspension as of 30 September 2022. At initiation, 66.7% were male, mean age ± SD was 61.2 ± 11.2 years, and 61.3% were covered by government insurance. In patients with provider–recorded ALSFRS-R (n = 115) and FVC (n = 84) %–predicted measures within ± 100 days from care initiation, mean ± SD values were 35.1 ± 8.9 and 72.3% ± 21.7%, respectively. Mean ± SD therapy duration was 13.5 ± 11.4 months. Discontinuation reasons included death/hospice (n = 82), patient’s choice (n = 38), doctor’s choice (n = 31), insurance (n = 18), and other (n = 12). Reasons for IV edaravone discontinuation and IV edaravone administration access device were not associated.Conclusions Treatment discontinuation was primarily related to ALS disease progression/death, rather than safety or tolerability. This study representative of real-world patients with ALS suggests that edaravone showed consistent safety and tolerability profiles with previous studies.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
