Research, made easier to explore

Clinical studies looking for participants

What's being studied, where it's happening and whether it's recruiting. Start with your state and recruitment status, then open a few studies. Your care team decides eligibility.

"Recruiting" is the study's registry status, not a guarantee of a space near you. State filters use the listed study sites; open a study to see each site. Studies marked Hand-checked were reviewed against recent announcements in October 2026 and carry extra notes.
Understand the stages

What the phases mean

Phase 1 studies test safety in a small group, often with increasing doses. Phase 2 looks for signs of benefit and the right dose. Phase 3 compares the treatment with placebo in larger numbers to confirm benefit; these are the studies that lead to approval. Expanded access programs provide an investigational drug outside a trial to people who can't join one. Observational studies and registries collect information and samples without testing a treatment, and some can be done from home.

Platform trials like the HEALEY ALS Platform Trial test several drugs at once with a shared placebo group, so more participants get an active drug. Enrollment opens and closes by regimen.

Before you join

Questions to ask the study team

  • What is being tested, and what's the chance I get a placebo?
  • Is there an open-label extension where everyone gets the drug?
  • How many visits, how far, and are travel and lodging reimbursed?
  • Can I keep taking riluzole, edaravone or other medications?
  • Will joining this study keep me out of other trials?
  • What happens to my care when the study ends?
