Abstract
Inflammatory bowel disease (IBD) is characterized by periods of flare-ups and remission. It is likely to be an autoimmune in origin, presenting persistent therapeutic challenges despite current therapies. This study aims to investigate the potential of umbilical cord mesenchymal stromal cells (UCMSCs) in treating ulcerative colitis (UC). This study is a prospective phase 1 pilot, open-label, single-arm, and single-center study. UCMSCs were cultured under current Good Manufacturing Practice (cGMP) conditions and intravenously administered to six patients with UC. Safety and efficacy were evaluated using the Mayo Score/Disease Activity Index. Among the six enrolled adult patients, five completed long-term follow-ups. All exhibited at diagnosis active UC confirmed through comprehensive assessment methods. Each patient received three injections intravenously 2 weeks apart with a dose of 100 million UCMSC each. No significant short-term or intermediate-term adverse events were detected post-UCMSC administration. Long-term follow-up at 12 and 24 months showed sustained safety and no adverse events. Notably, three out of five patients achieved a Mayo score of 0 for UC, maintained at both 12 and 24 months, indicating a highly significant response (P < 0.001). This study demonstrates the safety and potential efficacy of UCMSCs in active UC. However, larger trials are warranted to validate these preliminary findings and to establish the role of UCMSC therapy as an option for managing UC.
