Vitamin D treatment after intracerebral hemorrhage

Official title: Vitamin D Treatment in IntraCerebal Hemorrhage To Enhance Hematoma Resolution (VICToHR): a Pilot Study

Run by The University of Hong Kong · NCT07458815 · Data updated 2026-11-12

This will try giving higher-dose vitamin D to adults within 96 hours of an intracerebral hemorrhage to see if it helps clear the bleed faster and is safe.

Is this trial a fit for you?

Likely a good fit

Adults with spontaneous supratentorial ICH who present within 96 hours, have premorbid mRS ≤2, an ICH volume ≥2 mL, and no contraindications to vitamin D are ideal candidates.

Probably not a fit

Patients with severe coma (GCS <9), those expected to need surgical hematoma evacuation, with hypercalcemia, severe renal or liver impairment, or who present late (>96 hours) are unlikely to benefit or are excluded.

What this trial studies

This is a prospective, randomized, open-label, blinded-endpoint (PROBE) pilot comparing vitamin D supplementation versus standard care in adults with spontaneous supratentorial intracerebral hemorrhage. Participants are randomized 1:1 to receive vitamin D 4000 IU daily for two weeks then 1000 IU daily for 24 weeks, or standard care, with neuroradiologists blinded for hematoma measurements. The primary outcomes are the rate of hematoma resolution at 14 days and the incidence of hypercalcemia and vitamin D toxicity; hematoma volume change is centrally read by a blinded rater. Key eligibility includes age ≥18, presentation within 96 hours of ICH, premorbid mRS ≤2, and ICH volume ≥2 mL, while patients with severe organ dysfunction, hypercalcemia, or anticipated surgical evacuation are excluded.

Why it matters

Potential benefit: If successful, this could speed hematoma clearance and reduce secondary brain injury using an inexpensive, widely available supplement.

How similar studies have gone: Preclinical mouse studies demonstrated improved hematoma clearance and function with high-dose vitamin D, but human data for ICH are novel and limited.
