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 D will evaluate the safety and efficacy of a single study drug, pridopidine, in participants with ALS.
Eligibility Criteria
Inclusion Criteria
- No additional inclusion criteria beyond the inclusion criteria specified in the Master Protocol (NCT NCT04297683).
Exclusion Criteria
- The following exclusion criteria are in addition to the exclusion criteria specified in the Master Protocol (NCT NCT04297683).

- Participants with clinically significant heart disease, clinically significant history of arrhythmia, symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia, or presence of left bundle branch block.
- Participants with known history of long QT syndrome or a first degree relative with this condition.
- Participants using prohibited medications within the 4 weeks prior to the Regimen Specific Screening Visit, as detailed in section 5.9.
- Participants using the following medications at the time of the Regimen Specific Screening Visit:
- Nuedexta - at a dosage higher than 20 mg dextromethorphan + 10 mg quinidine BID
- Citalopram - at a dosage higher than 20 mg/day
- Escitalopram - at a dosage higher than 10 mg/day
- Participants with a known allergy to any ingredient of the study intervention (pridopidine, silicified microcrystalline cellulose, and magnesium stearate).
