Full 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. The HEALEY ALS Platform Trial Master Protocol is registered as NCT04297683.

Once a participant enrolls into the Master Protocol and meets all eligibility criteria, the participant will be eligible to be randomized into any currently enrolling regimen. All participants will have an equal chance of being randomized to any currently enrolling regimen.

If a participant is randomized to Regimen B - Verdiperstat, the participant will complete a screening visit to assess additional Regimen B eligibility criteria. Once Regimen B eligibility criteria are confirmed, participants will complete a baseline assessment and be randomized in a 3:1 ratio to either active Verdiperstat or matching placebo.

Regimen B will enroll by invitation as participants may not choose to enroll in Regimen B. Participants must first enroll into the Master Protocol and be eligible to participate in the Master Protocol before being able to be randomly assigned to Regimen B.

For a list of enrolling sites, please see the HEALEY ALS Platform Trial Master Protocol under NCT04297683.
