Key findings

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

    1 of 8 indexed trials (12.5%) 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 Progesterone Receptor Positive research.

    National Cancer Institute (NCI) accounts for 3 of 8 trials (37.5%). 5 distinct sponsors appear on at least one study for this condition label.

  3. Typical Progesterone Receptor Positive enrolment sits around 200 participants.

    Median target enrolment is 200 among the 8 trials that report a genuine target (sentinel values excluded). 4 of those (50%) plan for fewer than 100 participants.

  4. Progesterone Receptor Positive research is mostly interventional.

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