Key findings

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

    13 of 108 indexed trials (12%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Hepatitis C trials is spread across many organizations.

    Gilead Sciences accounts for 7 of 108 trials (6.5%). 67 distinct sponsors appear on at least one study for this condition label.

  3. Typical Hepatitis C enrolment sits around 115 participants.

    Median target enrolment is 115 among the 107 trials that report a genuine target (sentinel values excluded). 49 of those (45.8%) plan for fewer than 100 participants.

  4. Hepatitis C research is mostly interventional.

    86 interventional and 22 observational studies make up this index (79.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
