Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 2b/3, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, 12 Month Clinical Trial to Evaluate the Efficacy and Safety of MN-166 (Ibudilast) Followed by Open-Label Extension Phase in Subjects With Amyotrophic Lateral Sclerosis
Actual Study Start Date : May 28, 2020
Estimated Primary Completion Date : December 2023
Estimated Study Completion Date : December 2024

Arm Intervention/treatment
Experimental: MN-166
Subjects will take MN-166 10 mg capsules, up to 50 mg twice a day, along with a stable dose of riluzole, daily for 12 months.
Drug: MN-166

Other Name: ibudilast

Placebo Comparator: placebo
Subjects will take up to 5 matching placebo capsules twice a day, along with a stable dose of riluzole, daily for 12 months.
Drug: placebo
Subjects will take matching placebo with a stable dose of riluzole for 12 months followed by a 6-month open-label extension phase.

Primary Outcome Measures :
  1. Change from baseline in ALSFRS-R score at Month 12 (or last measurement before death in case of censoring) and survival time. [ Time Frame: 12 months ]
    The amyotrophic lateral sclerosis functional rating scale-revised, or ALSFRS-R, measures the functional status of subjects with ALS. It is based on 12 items, each of which is rated on a 5-point scale (0 to 4). The rate of total functional disability thus ranges from 0 (maximum disability) to 48 (normal function) points.

Secondary Outcome Measures :
  1. Mean change from baseline of muscle strength measured by hand-held dynamometry [ Time Frame: Baseline, Treatment Phase Week 6, Months 3, 6, 9 and12 time points. ]
    Hand-held dynamometry, or HHD, is used to measure the force generated by each muscle. The scale ranges from 0 (no visible movement of the part) to 10 (holds test position against strong pressure). Thus, the higher the total score, the higher muscle strength is observed.

  2. Mean change from baseline on quality of life assessed by ALSAQ-5 at Month 12 [ Time Frame: 12 months ]
    The Amyotrophic Lateral Sclerosis Assessment Questionnaire, or ALSAQ-5, is a patient self-report questionnaire specifically designed to measure 5 areas of health: physical mobility, activities of daily living and independence, eating and drinking, communication and emotional functioning. The subject is asked about 5 different areas of difficulties in their daily lives: ability to stand up, use of limbs, consuming solid food, level of speech coherence, and degree of hope about the future.Each question provides 5 choices from which to choose: Never, Rarely, Sometimes, Often, and Always or cannot do at all.

  3. Mean change from baseline of functional activity measured by ALSFRS-R at Month 12 [ Time Frame: 12 months ]
    The ALSFRS-R assessment tool measures the functional status of subjects with ALS. It is based on 12 items, each of which is rated on a 5-point scale (0 to 4). The rate of total functional disability thus ranges from 0 (maximum disability) to 48 (normal function) points. In this context, the ALSFRS-R total score change (lower, same, higher) is documented.

  4. Responders, measured in percent of subjects overall, whose ALSFRS-R total score was stable or improved [ Time Frame: 12 months ]
    Proportion of subjects in which ALSFRS-R total score was stable or improved.

  5. Time to survival [ Time Frame: 12 months ]
    Defined by death or permanent dependency to ventilator or tracheostomy.

  6. Number of Participants with Treatment-Related Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: 12 months ]
    The incidence of treatment-emergent adverse events (TEAEs), severity (mild, moderate, severe), as well as relationship to study treatment (not related, possibly related, probably related) and whether they are considered serious.

  7. Changes from Baseline in Laboratory Values [ Time Frame: 12 months ]
    Incidence of out-of-normal-range values and markedly abnormal change from baseline in laboratory safety test variables by treatment group.
