Clinical Trial 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Clinical efficacy rate 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%. Change from Baseline Clinical efficacy rate at 8th and 16th week, and the first week after the end of treatment.
Primary Clinical response rate 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%. Change from Baseline Clinical response rate at 8th and 16th week, and the first week after the end of treatment.
Secondary Clinical symptom score 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. Change from Baseline clinical symptom score at the first week after the end of treatment.
Secondary Endoscopic response rate 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%. Change from Baseline endoscopic response rate at the first week after the end of treatment.
Secondary Mucosal healing rate 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%. Change from Baseline mucosal healing rate at the first week after the end of treatment.
