Clinical Trial Summary

Thirty cases of amyotrophic lateral sclerosis patients were recruited from the neurology department of Ruijin Hospital, the pain department and the encephalopathy center of Luwan Branch of Ruijin Hospital. After the informed consent was signed, they were divided into a trial group and a control group. Each group contains 15 cases. The patients in the control group was treated with edaravone dissolved in saline during hospitalization, while the patients in the trial group was treated with edaravone, scopolamine, atropine and dexmedetomidine. Both groups of subjects were treated for 7 days within 3 weeks, followed by a buffer period of 3 weeks for observation, which was one treatment course. The total treatment protocol contains 3 treatment courses (or 18 weeks). Patients with amyotrophic lateral sclerosis were evaluated before treatment and 6, 12, 18, 24, 36, 48 weeks after treatment. The observations include whether the functional scores of patients with amyotrophic lateral sclerosis, Norris amyotrophic lateral sclerosis score, amyotrophic lateral sclerosis self-score, forced expiratory volume in one second, partial pressure of oxygen and maximum displacement of the hyoid were superior to those before treatment, and whether the partial pressure of carbon dioxide was inferior to those before treatment. Study hypothesis: Cholinergic receptor blocking therapy for amyotrophic lateral sclerosis is safe and effective in improving motor function and delaying disease progression in patients with amyotrophic lateral sclerosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effective	Forced expiratory volume in one second (FVC%) or ALS functional rating scale score (ALSFR, minimum score: 0, maximum score: 48, higher score is related to a better outcome) was elevated.	48 weeks
Primary	Ineffective	Forced expiratory volume in one second (FVC%) or ALS functional rating scale score (ALSFR, minimum score: 0, maximum score: 48, higher score is related to a better outcome) was decreased or remained unchanged.	48 weeks
Secondary	Effective	Partial pressure of oxygen (PO2), maximum displacement of the hyoid or the modified Norris scale score (minimum score: 0, maximum score: 100, higher score is related to a better outcome) was elevated or partial pressure of carbon dioxide (PCO2) was decreased or remained unchanged.	48 weeks
Secondary	Ineffective	Partial pressure of carbon dioxide (PCO2) was elevated, or partial pressure of oxygen (PO2), maximum displacement of the hyoid or the modified Norris scale score (minimum score: 0, maximum score: 100, higher score is related to a better outcome) was decreased or remained unchanged.	48 weeks
