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.
Interventions
Human umbilical cord MSCs are transplanted three times by intravenous infusion(1×10\^6/kg) ,once every week,a total of three times.
Normal saline in same volume as MSCs are transplanted to patients.

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