Clinical Trial 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.

Regimen G will evaluate the safety and efficacy of a single study drug, DNL343, in participants with ALS.

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 G DNL343, the participant will complete a screening visit to assess additional Regimen G eligibility criteria. Once Regimen G eligibility criteria are confirmed, participants will complete a baseline assessment and be randomized in a 3:1 ratio to either active DNL343 or matching placebo.

Regimen G will enroll by invitation, as participants may not choose to enroll in Regimen G. 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 G.

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease Progression	Change in disease severity over time as measured by the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) total score and survival. 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.	24 Weeks
Secondary	Function	Change in ALSFRS-R total score over time. 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.	24 Weeks
Secondary	Combined Assessment of Function and Survival (CAFS)	Combined assessment of function and survival uses ALSFRS-R total score as the function measure and death or permanent assisted ventilation as the survival component.; The Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) total score and survival. 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.	24 Weeks
Secondary	Respiratory Function	Change in respiratory function over time as assessed by slow vital capacity (SVC)	24 Weeks
Secondary	Muscle Strength	Change in muscle strength over time as measured isometrically using hand-held dynamometry and grip strength	24 Weeks
Secondary	Survival	Survival evaluated as time to death or permanent assisted ventilation (PAV)	24 Weeks
Secondary	Survival	Survival evaluated as time to death	24 Weeks
