Key findings

What ClinicalTrials.gov does not surface for Recurrent Acute Lymphoblastic Leukemia 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. Recurrent Acute Lymphoblastic Leukemia is recruiting above its size-band peers.

    9 of 18 indexed trials (50%) 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 Recurrent Acute Lymphoblastic Leukemia research.

    M.D. Anderson Cancer Center accounts for 7 of 18 trials (38.9%). 8 distinct sponsors appear on at least one study for this condition label.

  3. Most Recurrent Acute Lymphoblastic Leukemia trials plan to enrol fewer than 100 people.

    Median target enrolment is 54 among the 18 trials that report a genuine target (sentinel values excluded). 15 of those (83.3%) plan for fewer than 100 participants.

  4. Recurrent Acute Lymphoblastic Leukemia research is mostly interventional.

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