Eligibility
Inclusion criteria
1. Subjects must provide a signed and dated informed consent form (ICF) to participate in the study. Subjects must be able (in the judgment of the Investigator) to understand the nature of the study and all risks involved with participation in the study. Subjects must be willing to cooperate and comply with all protocol restrictions and requirements. 2. Subjects will be male or female, ≥ 18 to 75 years of age at the time the ICF is signed. 3. Subjects will be diagnosed with Definite ALS or Probable ALS according to the El Escorial revised criteria for the diagnosis of ALS. 4. Subjects with a baseline score ≥ 2 points on each individual item of the ALSFRS- R at screening and baseline visits. 5. Subjects have a screening and baseline %forced vital capacity (FVC) ≥ 70%. 6. Subjects with 1- to 4-point decline for 8 weeks (±7 days) in ALSFRS-R total score between screening and baseline visits. 7. Subjects whose first symptom of ALS has occurred within 2 years of providing written informed consent.
Exclusion criteria
Exclusions Related to Primary Diagnosis 1. Subjects with a history of spinal surgery after the onset of ALS, such as surgery for cervical spondylosis or a herniated disc, or plans for such surgery during the study period. Exclusions Related to Other Neurological Disorders (including, but not limited to the following) 2. Subjects with the possibility that the current symptoms may be symptoms of a disease requiring differential diagnosis, such as cervical spondylosis and multifocal motor neuropathy, cannot be ruled out. Exclusions Related to General Health or Concomitant Conditions 3. Subjects undergoing treatment for a malignancy. 4. Subjects with a complication that could have a significant effect on efficacy evaluations, such as Parkinson's disease or syndrome, schizophrenia, bipolar disorder, and dementia. 5. Subjects who have the presence or history of any clinically significant (CS) disease (except ALS) that could interfere with the objectives of the study (the assessment of safety and efficacy) or the safety of the subject, as judged by the Investigator. 6.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| CAFS Score at Week 48 | up to 48 Weeks | CAFS ranks patients' clinical outcomes based on survival time and change in the ALSFRS-R score. To calculate a patient's CAFS, each patient is compared individually to all other patients in the study. The summary score for each patient is the sum of the comparisons ( 1, 0, 1) against all other patients. After that, patients' summary scores are ranked. The CAFS rank is 1-383 and a higher CAFS rank indicates a better outcome than does a lower CAFS. Since CAFS were calculated using the imputed ALSFRS-R scores with multiple imputation method, and the maximum varies for each simulation, 383 is the maximum possible value of full range for measure of dispersion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in % Slow Vital Capacity (SVC) at Week 48 | up to 48 Weeks | SVC measurements will be conducted in clinic at around the same time of day where possible with the subject in sitting upright position. Subjects should make at least 3 attempts to generate acceptable and reproducible SVC data. The highest value was selected and recorded. |
| Change From Baseline in Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ)40 at Week 48 | up to 48 Weeks | The ALSAQ-40 is a questionnaire that consists of 40 questions/items with 5 discrete scales: physical mobility, activities of daily living and independence, eating and drinking, communication, emotional reactions, ranging from 0 (best health as assessed by the scale) to 100 (worse health as assessed by the measure). |

Outcome results
CAFS Score at Week 48
CAFS ranks patients' clinical outcomes based on survival time and change in the ALSFRS-R score. To calculate a patient's CAFS, each patient is compared individually to all other patients in the study. The summary score for each patient is the sum of the comparisons ( 1, 0, 1) against all other patients. After that, patients' summary scores are ranked. The CAFS rank is 1-383 and a higher CAFS rank indicates a better outcome than does a lower CAFS. Since CAFS were calculated using the imputed ALSFRS-R scores with multiple imputation method, and the maximum varies for each simulation, 383 is the maximum possible value of full range for measure of dispersion.
Time frame: up to 48 Weeks
Population: One subject randomized to the On/Off treatment group was excluded from this analysis because the subject did not receive any study treatment.
| Arm | Measure | Value (MEAN) |
|---|---|---|
| Edaravone 105 mg (Once Daily) | CAFS Score at Week 48 | 187.2 Units on a scale |
| Edaravone 105mg (2 Weeks On/Off ) | CAFS Score at Week 48 | 184.2 Units on a scale |
