3) Patients who can go to outpatient clinic

Exclude criteria

1) Patients who have clinically significant complications or medical history other than ALS, and who are judged to be inappropriate for clinical study by the investigator.
2) Patients with psychiatric disorders, cognitive impairment, or Parkinson's disease.
3) Patients undergoing tracheostomy.
4) Patients wearing a non-invasive respiratory support device all day (wearing for 22 hours or more).
5) Patients with a history of or complication of drug allergy or severe allergic disease (anaphylactic shock, etc.).
