HEALEY ALS Platform Trial - Master Protocol

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 I - NUZ-001 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.
