Brief Summary:
The HEALEY ALS Platform Trial is a perpetual multi-center, multi-regimen clinical trial evaluating the safety and efficacy of investigational products for the treatment of ALS.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Zilucoplan Drug: Verdiperstat Drug: CNM-Au8 Drug: Pridopidine Drug: SLS-005 Trehalose Drug: ABBV-CLS-7262 Drug: DNL343 Phase 2 Phase 3

Detailed Description:

The HEALEY ALS Platform Trial is a perpetual multi-center, multi-regimen clinical trial evaluating the safety and efficacy of investigational products for the treatment of ALS. This trial is designed as a perpetual platform trial. This means that there is a single Master Protocol dictating the conduct of the trial.

In this trial, multiple investigational products for ALS will be tested simultaneously or sequentially. Each investigational product will be tested in a regimen. Each regimen consists of a placebo-controlled trial, meaning that the active investigational product and matching placebo will be tested in each regimen.

The additional details that govern the testing of each investigational product will be summarized in separate regimen-specific appendices (RSAs). Each regimen will have a separate ClinicalTrials.gov posting, which will include specific information about the regimen. All regimen-specific outcome measures will be detailed in each regimen posting.

Participants will have an equal chance to be randomized to all regimens that are active at the time of screening. Once randomized to a regimen, participants will be randomized in a 3:1 ratio to either study drug or placebo.

The following regimens are active in the trial:

Regimen A - Zilucoplan Regimen B - Verdiperstat Regimen C - CNM-Au8 Regimen D - Priodopidine Regimen E - SLS-005 Trehalose Regimen F - ABBV-CLS-7262 Regimen G - DNL343

New regimens will be continuously added as new investigational products become available. The HEALEY ALS Platform Trial will enroll additional participants as each new regimen is available.

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. Disease Progression [ Time Frame: 24 Weeks ]
    Change in disease severity over time as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R). Each type of function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. Patients with higher scores have more physical function.


Secondary Outcome Measures :
  1. Respiratory Function [ Time Frame: 24 Weeks ]
    Change in respiratory function over time as measured by Slow Vital Capacity (SVC).

  2. Muscle Strength [ Time Frame: 24 Weeks ]
    Change in muscle strength over time as measured isometrically using hand-held dynamometry (HHD).

  3. Survival [ Time Frame: 24 Weeks ]
    Comparison of rate of occurrence between groups.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Sporadic or familial ALS diagnosed as clinically possible, probable, lab-supported probable, or definite ALS defined by revised El Escorial criteria.
  2. Age 18 years or older.

  4. Time since onset of weakness due to ALS ≤ 36 months at the time of the Master Protocol Screening Visit.
  5. Vital Capacity ≥ 50% of predicted capacity at the time of the Master Protocol Screening Visit measured by Slow Vital Capacity (SVC), or, if required due to pandemic-related restrictions, Forced Vital Capacity (FVC) measured in person.
  6. Participants must either not take riluzole or be on a stable dose of riluzole for ≥ 30 days prior to the Master Protocol Screening Visit.
  7. Participants must either not take edaravone or have completed at least one cycle (typically 14 days) of edaravone prior to the Master Protocol Screening Visit.
  8. Participants must have the ability to swallow pills and liquids at the time of the Master Protocol Screening Visit and, in the SI's opinion, have the ability to swallow for the duration of the study.

The following values [alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 3 times the upper limit of normal (ULN) or estimated Glomerular Filtration Rate (eGFR) < 30 mL/min/1.73m2] are exclusionary regardless of clinical symptoms.
  2. Presence of unstable psychiatric disease, cognitive impairment, dementia or substance abuse that would impair ability of the participant to provide informed consent, in the SI's opinion.
  3. Active cancer or history of cancer, except for the following: basal cell carcinoma or successfully treated squamous cell carcinoma of the skin, cervical carcinoma in situ, prostatic carcinoma in situ, or other malignancies curatively treated and with no evidence of disease recurrence for at least 3 years.

  8. Anything that would place the participant at increased risk or preclude the participant's full compliance with or completion of the study, in the SI's opinion.
  9. If a participant is being re-screened, the disqualifying condition has not been resolved, or the mandatory wash-out duration has not occurred.
