Overview
Brief Summary
A prospective, open-label, phase 2a study, to evaluate the pharmacokinetic (PK) profile, safety, and efficacy of multiple doses of Cannabidiol (CBD) in participants Graft-Versus-Host Disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT)
Detailed Description
The study contains 3 cohorts of 12 participants each: All participants will be orally administered for 105 days with CBD at doses of 75, 150 or 300 mg (PO) BID for the prevention of acute GVHD (aGVHD) following allogeneic HSCT. In addition to the study drug, all participants will receive standard aGVHD prophylaxis consisting of a calcineurin inhibitor (cyclosporine or tacrolimus) and a short course of methotrexate (MTX). After completion of 105 treatment days, the participant will be followed-up until day 180.
