Brief Summary:
To evaluate and compare the efficacy of two dosing regimens of oral edaravone in subjects with amyotrophic lateral sclerosis (ALS) based on the change in ALS Functional Rating Scale- Revised (ALSFRS-R) score from baseline up to Week 48:

Condition or disease Intervention/treatment Phase
ALS Drug: MT-1186 Drug: Placebo Phase 3

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 380 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3b, Multicenter, Randomized, Double-Blind Study to Evaluate Efficacy and Safety of Oral Edaravone Administered for a Period of 48 Weeks in Subjects With Amyotrophic Lateral Sclerosis (ALS)
Actual Study Start Date : November 13, 2020
Estimated Primary Completion Date : July 2023
Estimated Study Completion Date : July 2023

Arm Intervention/treatment
Experimental: MT-1186 Drug: MT-1186
Oral edaravone
Other Name: Oral edaravone

Experimental: MT-1186 and Placebo Drug: MT-1186
Oral edaravone
Other Name: Oral edaravone

Drug: Placebo

Primary Outcome Measures :
  1. Change in ALS Functional Rating Scale- Revised (ALSFRS-R) score from baseline to Week 48 of treatment [ Time Frame: up to 48 Weeks ]
    The ALSFRS-R is rating scale (ratings 0 = can't do, to 4 = normal ability) used to determine participants' assessment of their capability and independence in 12 functional activities.

Secondary Outcome Measures :
  1. Change from baseline in % slow vital capacity (SVC) at Week 48 [ Time Frame: up to 48 Weeks ]
  2. Change from baseline in Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ)40 at Week 48 [ Time Frame: 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).

Other Outcome Measures:
  1. Time to death, tracheostomy or permanent assisted mechanical ventilation (≥ 23 hours/day) [ Time Frame: up to 48 Weeks ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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. Subjects who are female, of childbearing potential, and pregnant (a positive pregnancy test) or lactating at the screening visit (Visit 1).
  7. Subjects of childbearing potential unwilling to use acceptable method of contraception from the screening visit until 3 months after the last dose of study medication. Subjects who are sexually active who do not agree to use contraception during the study period.
  8. Subjects who have a significant risk of suicidality. Subjects with any suicidal behavior or suicidal ideation of type 4 (active suicidal ideation with some intent to act, without a specific plan) or type 5 (active suicidal ideation with specific plan and intent) based on the Columbia-Suicide Severity Rating Scale (C-SSRS) within the 3 months before the screening visit.
  9. Subjects who have alanine aminotransferase (ALT) or aspartate aminotransferase (AST) elevations greater than 2 times the upper limit of normal (ULN) at screening.
  10. Subjects with a Glomerular Filtration Rate (GFR) < 30 mL/Min Per 1.73 m2 at screening, using the Larsson Equation.

    Exclusions Related to Medications

  11. Subjects with history of hypersensitivity to edaravone, any of the additives or inactive ingredients of edaravone, or sulfites.
  12. Subjects with hereditary problems of fructose intolerance (eg, fructose, sucrose, invert sugar, and sorbitol).
  13. Subjects who participated in another study and were administered an investigational product within 1 month or 5 half-lives of the investigational agent, whichever is longer, before providing informed consent for the present study.
  14. Subjects who have received any previous treatment with edaravone.
  15. Subjects who have received stem cell therapy.
  16. Subjects who are unable to take their medications orally at baseline (Visit 2).
