Safety and tolerability of a single infusion of autologous ex vivo expanded regulatory T cells in adults with ulcerative colitis (ER-TREG 01): protocol of a phase 1, open-label, fast-track dose-escalation clinical trial.

ABSTRACT:

Introduction

Accumulating evidence suggests that the adoptive transfer of ex vivo expanded regulatory T cells (Treg) may overcome colitogenic immune responses in patients with inflammatory bowel diseases. The objective of the ER-TREG 01 trial is to assess safety and tolerability of a single infusion of autologous ex vivo expanded Treg in adults with ulcerative colitis.

Methods and analysis

The study is designed as a single-arm, fast-track dose-escalation trial. The study will include 10 patients with ulcerative colitis. The study intervention consists of (1) a baseline visit; (2) a second visit that includes a leukapheresis to generate the investigational medicinal product, (3) a third visit to infuse the investigational medicinal product and (4) five subsequent follow-up vi
