Key findings

What ClinicalTrials.gov does not surface for Spondylolisthesis 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. Spondylolisthesis is recruiting below its size-band peers.

    6 of 19 indexed trials (31.6%) are open to enrollment, against a 46.5% average across 27,806 conditions with fewer than 20 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

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

    Francis Farhadi accounts for 2 of 19 trials (10.5%). 17 distinct sponsors appear on at least one study for this condition label.

  3. Typical Spondylolisthesis enrolment sits around 100 participants.

    Median target enrolment is 100 among the 19 trials that report a genuine target (sentinel values excluded). 9 of those (47.4%) plan for fewer than 100 participants.

  4. Spondylolisthesis splits between interventional and observational designs.

    12 interventional and 7 observational studies make up this index (63.2% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
