Key findings

What ClinicalTrials.gov does not surface for Multiple Sclerosis 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. Multiple Sclerosis recruits in line with its size-band peers.

    120 of 317 indexed trials (37.9%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Multiple Sclerosis trials is spread across many organizations.

    Biogen accounts for 13 of 317 trials (4.1%). 142 distinct sponsors appear on at least one study for this condition label.

  3. Typical Multiple Sclerosis enrolment sits around 61 participants.

    Median target enrolment is 61 among the 316 trials that report a genuine target (sentinel values excluded). 181 of those (57.3%) plan for fewer than 100 participants.

  4. Multiple Sclerosis research is mostly interventional.

    231 interventional and 86 observational studies make up this index (72.9% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
