Key findings

What ClinicalTrials.gov does not surface for Refractory Plasma Cell Myeloma 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. Refractory Plasma Cell Myeloma is recruiting below its size-band peers.

    4 of 26 indexed trials (15.4%) 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. One sponsor concentrates Refractory Plasma Cell Myeloma research.

    Fred Hutchinson Cancer Center accounts for 5 of 26 trials (19.2%). 12 distinct sponsors appear on at least one study for this condition label.

  3. Most Refractory Plasma Cell Myeloma trials plan to enrol fewer than 100 people.

    Median target enrolment is 30 among the 26 trials that report a genuine target (sentinel values excluded). 23 of those (88.5%) plan for fewer than 100 participants.

  4. Refractory Plasma Cell Myeloma research is mostly interventional.

    26 interventional and 0 observational studies make up this index (100% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
