Key findings

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

    11 of 40 indexed trials (27.5%) 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. Sponsorship of Hypoxia trials is spread across many organizations.

    Nihon Kohden accounts for 4 of 40 trials (10%). 31 distinct sponsors appear on at least one study for this condition label.

  3. Most Hypoxia trials plan to enrol fewer than 100 people.

    Median target enrolment is 37 among the 40 trials that report a genuine target (sentinel values excluded). 29 of those (72.5%) plan for fewer than 100 participants.

  4. Hypoxia splits between interventional and observational designs.

    20 interventional and 20 observational studies make up this index (50% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
