Intrauterine Adhesion Clinical Trial
Official title:
Safety and Efficacy of Intrauterine Biological Barrier on Postoperative Adhesion After Hysteroscopic Adhesiolysis: a Prospective, Multicentre, Randomized, Positive Parallel Controlled, Non-inferiority, Clinical Trail
To evaluate the safety and efficacy of Intrauterine Biological Barrier developed and produced by Chengdu TopRegMed Medical Technology Co., Ltd on postoperative adhesion after Hysteroscopic Adhesiolysis.
This study is a prospective, multicenter, randomized, parallel positive-control, non-inferior clinical trial, with the purpose to evaluate the efficacy and safety of Intrauterine Biological Barrier for the prevention or reduction of intrauterine adhesions after Hysteroscopic Adhesiolysis. The trial will be conducted at six clinical centers with 264 subjects who meet all the inclusion/ exclusion criteria. Subjects will be randomly assigned to the experimental group and the control group in a 1:1 ratio. Subjects in the test group were treated with Intrauterine Biological Barrier (IBB) made by Chengdu TopRegMed Medical Technology Co. , Ltd. , while the patients in the positive control group were treated with commercially approved Intrauterine Adhesion Barrier Gel for uterine cavity made by Changzhou Bioregen biopharmaceutical Co. , Ltd. . Subjects will be followed up for 12 months (360 days ± 30 days) after implantation. 73-days (± 12 days) after operation, the safety and effectiveness of IBB will be evaluated by demonstrating non-inferiority to commercially approved gel. If test group is non-inferiority, further study will be performed to explore whether the safety and effectiveness of the IBB is better than the control group in the aspect of the recurrence rate of intrauterine adhesion, types of intrauterine adhesion, postoperative endometrial repair, menstrual recovery and 1-year pregnancy rate. ;
