Key findings

What ClinicalTrials.gov does not surface for ALS on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. ALS is recruiting above its size-band peers.

    10 of 20 indexed trials (50%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of ALS trials is spread across many organizations.

    Amylyx Pharmaceuticals accounts for 2 of 20 trials (10%). 19 distinct sponsors appear on at least one study for this condition label.

  3. Most ALS trials plan to enrol fewer than 100 people.

    Median target enrolment is 75 among the 20 trials that report a genuine target (sentinel values excluded). 13 of those (65%) plan for fewer than 100 participants.

  4. ALS splits between interventional and observational designs.

    11 interventional and 9 observational studies make up this index (55% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
