Safety and Effectiveness of Vedolizumab in Patients with Steroid-Refractory GI Acute GvHD: A Retrospective Record Review

Research output: Contribution to journalArticle

Abstract

Allogeneic hematopoietic cell transplantation can be curative in patients with hematological malignancies but carries a significant risk of graft-versus-host disease (GvHD). There are no standard treatments for steroid-refractory (SR) gastrointestinal (GI) acute GvHD (aGvHD). This multicenter, international, retrospective medical record review aimed to evaluate the off-label use of vedolizumab, a gut-selective immunomodulator, for treatment of SR GI aGvHD. Data from medical records of patients were collected, and criteria for extraction included: no more than 1 allogeneic hematopoietic cell transplantation and at least 1 dose of vedolizumab as treatment for SR GI aGvHD (stage I-IV GI aGvHD following ≥1 previous treatment regimen containing ≥1 mg/kg methylprednisolone or equivalent). Descriptive analyses of response rate, overall survival (OS), and serious adverse effects (SAEs) were performed. Twenty-nine patients were identified from 7 sites and had received 1-10 doses of IV vedolizumab 300 mg (median 3 doses) as treatment for SR GI aGvHD. The overall response rate at 6-10 weeks after vedolizumab initiation was 64% and OS at 6 months was 54%. There were 29 SAEs including 12 infections; 3 SAEs were considered possibly related to vedolizumab (2 of which were infections). Thirteen SAEs were fatal, 1 of which was possibly vedolizumab-related. There were 8 non-serious infections with confirmed GI origin and 1 serious (in 8 patients); there was no apparent pattern in the timing of these infections relative to the initiation of vedolizumab treatment. Further data on the efficacy and safety of vedolizumab in this setting are required from prospective trials.
