Summary

Inflammatory bowel disease patients who failed from at least two types of biologics or suffered refractory after at least twice surgery are defiened as difficult-to-treat IBD. It is reported a low five-year suvival rate around 15% of difficult-to-treat IBD patients. Cell therapy is a promising new strategy in auto-immune diseases beyond malignant cancers. Inbalanced immune microenvironment contribute to IBD and cell therapy should be a brighting selection of difficult-to-treat IBD. CNK-UT009 is an universal cellular immunotherapy targeted to auto-reactive T cells whose safety and effect were proved in patients with GVHD and type 1 diabetes mellius. Here, we conducted a single-arm open-label exploratory clinical study of CNK-UT cell therapy on difficult-to-treat IBD patients, mainly to explore the safety and define the maximum tolerated dose. Besides, the preliminary effect would also be evaluated.

Conditions

• Inflamatory Bowel Disease
• Crohn Disease (CD)
• Ulcerative Colitis (UC)

Interventions

Type	Name	Description
DRUG	injection of CNK-UT009	CNK-UT009 is a type of independent development universal cell therapy agent, the reagent would be injected intravenously. We set three preset dose levels (3\*7E positive cells/kg 、6\*7E positive cells/kg 和 1\*8E positive cells/kg) with a tapering dose of 1.5\*7E positive cells/kg. Total cells would be divided into several parts and be given in the cycle of two weeks, adjusted by the tolerance and adverse effects of our patients.
