Brief Summary:
A Phase 2b/3 multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy, safety and tolerability of MN-166 given to ALS participants for 12 months followed by a 6-month open-label extension phase.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: MN-166 Drug: placebo Phase 2 Phase 3

Detailed Description:

This is a Phase 2b/3 multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy, safety and tolerability of MN-166 followed by an open-label extension phase compared to matching placebo in subjects diagnosed with ALS.

The study will consist of a screening phase (up to 30 days) followed by a double-blind phase (12 months). Following the screening phase, subjects who continue to meet entry criteria will be randomly assigned to one of two treatment groups: MN-166 or matching placebo in a 1:1 ratio. Upon completion of the double-blind phase, subjects will be given the option to continue to the Open-label Extension Phase for a period of six months.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

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.
