Brief Summary

Intracerebral hemorrhage (ICH) is the most deadly and debilitating form of stroke. To date, effective treatment that could improve the functional outcome of ICH remained elusive. In a mice model of ICH, it was demonstrated that high dose Vitamin D (VitD) treatment enhanced hematoma resolution by promoting reparative macrophage differentiation and improved neurobehavioral performance in mice. Hence, this pilot study aimed to investigate the feasibility and safety of VitD treatment for ICH in human subjects. VICToHR is a prospective, randomized, open-label, blinded-endpoint (PROBE) trial. Participants will be randomized 1:1 to receive either VitD or standard care (control). The intervention group will receive VitD 4000 IU daily for 2 weeks, followed by 1000 IU daily for 24 weeks. The primary outcomes are the rate of hematoma resolution at 14 days and the incidence of hypercalcemia and VitD toxicity. Hematoma volume will be assessed by a neuroradiologist who is blinded to treatment allocation.
