Brief summary
This study conducted a systematic clinical observation of the clinical efficacy of UCB-MNCs in the treatment of hormone-resistant or hormone-dependent ulcerative colitis, in order to observe its clinical safety and efficacy.
Detailed description
This study adopts a randomized and controlled clinical research design. Patients are randomly divided into conventional treatment control group and UCB-MNCs treatment test group. The control group is given conventional treatment: prednisone combined azathioprine or adalimumab; the test group is given conventional treatment combined UCB-MNCs treatment, follow-up observations were carried out, in order to observe the clinical efficacy and safety of UCB-MNCs in the treatment of hormone resistance or hormone-dependent ulcerative colitis.
Interventions
Peripheral intravenous infusion method, infusion of umbilical cord blood mononuclear cell suspension 50ml (cell number 2×10\^8).
0.75 mg per kilogram per day for three months
1 mg per kilogram per day for three months
40mg every two weeks for three months

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical efficacy rate | Change from Baseline Clinical efficacy rate at 8th and 16th week, and the first week after the end of treatment. | According to the method of modified Mayo score calculation, it is defined as a decrease of ≥30% of the score or a decrease of ≥3 points relative to the baseline value, and a decrease of ≥1 point or a score of 0 or 1 in the sub-item score of blood in the stool, and this type of patient is judged Effective for treatment. Clinical effective rate = (effective number of people / total number of people in this group ) × 100%. |
| Clinical response rate | Change from Baseline Clinical response rate at 8th and 16th week, and the first week after the end of treatment. | According to the method of modified Mayo score calculation, it is defined as a score ≤ 2 points and no single sub-item score\> 1 point. Clinical remission rate =(number of remissions / total number of people in this group) × 100%. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical symptom score | Change from Baseline clinical symptom score at the first week after the end of treatment. | According to the scoring criteria for individual symptoms (diarrhea, mucus pus and blood in the stool, abdominal pain, tenesmus), the severity of symptoms is divided into 0, 2, 4, and 6 points. The higher the score, the more severe the symptoms. |
| Endoscopic response rate | Change from Baseline endoscopic response rate at the first week after the end of treatment. | According to the method of modified Mayo score, endoscopy found that the score decreased by at least 1 point from baseline. Endoscopic response rate = (number of endoscopic responders/total number of people in the group) × 100%. |
| Mucosal healing rate | Change from Baseline mucosal healing rate at the first week after the end of treatment. | According to the method of modified Mayo score, the absolute score of the endoscopy discovery score is 0 or 1 point. Mucosal healing rate = (mucosal healing number / total number of people in this group) × 100%. |
