Human Umbilical-Cord-Derived Mesenchymal Stem Cell Therapy in Active Ulcerative Colitis

Phase 1

• Conditions: Ulcerative Colitis
• Interventions: Other: Control group(Normal saline); Biological: UCMSC group

• Registration Number: NCT02442037
• Lead Sponsor: Affiliated Hospital to Academy of Military Medical Sciences

Brief Summary

Phase I-II Clinical Trial - Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with active ulcerative colitis，randomized, single blind, controlled prospective study.

Detailed Description

Phase I-II Clinical Trial - Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with active ulcerative colitis，randomized, single blind, controlled prospective study.

Thirty patients will be selected and randomized into two groups: the first group of 15 patients will receive a sole injection of UC-MSC and the remaining 15 patients will comprise the control group.

Every patient will maintain their standard treatment of active ulcerative colitis, with maximum tolerated dosage without side effects.

The day of infusion will be considered day zero. From that moment, followup will be divided into 0-1 week, 1 week-2 week,2 week-3 week, 3 week-1 month, and 3 month-6 months.

Clinical results will be analyzed after completion of 6 months of followup.

Arm && Interventions

Group	Intervention	Description
Control group(Normal saline)	Control group(Normal saline)	Patients will receive normal saline at the same time points as that in experimental group.
UCMSC group	UCMSC group	Human umbilical cord MSCs are administrated to patients by three intravenous infusion

Primary Outcome Measures

Name	Time	Method
Safety will be determined by the assessment of major adverse events.	Within the six months after intravenous infusion	Safety will be determined by the assessment of major adverse events defined as fever, allergy or any other intravenous infusion adverse events.

Secondary Outcome Measures

Name	Time	Method
Endoscopic improvement is assessed by UCEIS.	Post first cell transplantation 6 months	UCEIS is defined as Ulcerative Colitis Endoscopic Index of Severity.
Clinical response (CDAI points)	Post first cell transplantation: 3 weeks and months 1,3 and 6	CDAI is defined as Clinical Disease Activity Index.
Level of C-reactive protein	Post first cell transplantation: 3 weeks and months 1,3 and 6
