Key findings

What ClinicalTrials.gov does not surface for Primary Mediastinal Large B Cell Lymphoma 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. Primary Mediastinal Large B Cell Lymphoma is recruiting above its size-band peers.

    8 of 12 indexed trials (66.7%) 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. One sponsor concentrates Primary Mediastinal Large B Cell Lymphoma research.

    University of Washington accounts for 2 of 12 trials (16.7%). 11 distinct sponsors appear on at least one study for this condition label.

  3. Most Primary Mediastinal Large B Cell Lymphoma trials plan to enrol fewer than 100 people.

    Median target enrolment is 36 among the 12 trials that report a genuine target (sentinel values excluded). 10 of those (83.3%) plan for fewer than 100 participants.

  4. Primary Mediastinal Large B Cell Lymphoma research is mostly interventional.

    11 interventional and 1 observational studies make up this index (91.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
