Vedolizumab for prevention of graft-versus-host disease after allogeneic hematopoietic stem cell transplantation.

ABSTRACT: Acute graft-versus-host disease (aGVHD) remains a significant complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Vedolizumab could help prevent aGVHD by inhibiting the migration of both naive and activated lymphocytes into gut-associated lymphoid tissues and the lamina propria. We carried out a phase 1b, open-label, dose-finding study in adults undergoing allo-HSCT to evaluate the tolerability, safety, and pharmacokinetics of vedolizumab, and its effectiveness in reducing aGVHD. IV vedolizumab was administered on day -1, +13, and +42 with respect to allo-HSCT, starting at 75 mg and with dose escalation guided by tolerability and pharmacokinetics. A total of 24 participants was enrolled, and no dose-limiting toxicities were observed in either the 75-mg cohort (n
