What this trial studies

This Phase 2 interventional trial tests higher-dose combinations of antioxidant compounds that are considered safe, building on prior EH301 results. It enrolls adults aged 21–80 with laboratory-supported probable, probable, or definite ALS by a modified El Escorial criterion, and participants on riluzole must be on a stable dose for at least 30 days. The protocol expands the original antioxidant approach by using higher doses and will measure clinical outcomes related to disease progression and function to determine if the effect is reproducible. The single-site trial is conducted at the VA North Texas Health Care System in Dallas, Texas.

Who should consider this trial

Good fit: Ideal candidates are adults 21–80 with laboratory-supported probable, probable, or definite ALS who can give informed consent and remain on a stable riluzole dose if applicable.

Not a fit: Patients with other neurodegenerative diseases, unstable medical illness, HIV infection, limited capacity to consent, or recent substance abuse are excluded and therefore unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this low-risk, low-cost antioxidant approach could meaningfully slow or halt ALS progression and be widely accessible.

How similar studies have performed: A prior trial (EH301) reported beneficial effects of antioxidant therapy in ALS, and this Phase 2 effort aims to validate and extend those findings while antioxidant strategies have otherwise shown mixed results in larger ALS populations.
