Understanding how a nerve-protecting drug works in different ALS types

Researchers want to understand how Edaravone (a medication already approved by the FDA for ALS) works in different patients with different types of ALS. This trial is not testing a new drug—edaravone is prescribed as part of your regular care. Instead, the researchers will collect blood, urine, and spinal fluid samples to measure specific markers and figure out which types of ALS patients benefit most from this medication and how long they should take it.

ALS comes in different forms depending on which nerve cells are affected first, and the medication may work better for some types than others. By studying these biological markers in patients taking and not taking this medication, researchers hope to personalize treatment and understand the best approach for each patient.
