Brief summary

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.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Effective rateDay 73±12At second-look hysteroscopy after Hysteroscopic adhesiolysis, the effective rate (%) = (number of cured + number of apparent effect)/total number in the group × 100%

Secondary

MeasureTime frameDescription
Extent of uterine adhesionsDay 73±12The degree of uterine adhesions was assessed intraoperatively and at the second-look hysteroscopy with reference to the ESGE (European Society for Gynecological Endoscopy) criteria
Endometrial improvementDay -7 to day 1, Day 100±10Endometrial thickness in millimeter and change values in millimeter by Ultrasonic Diagnostic Equipment Transvaginal Ultrasonic Probe Head at screening and visit 4
Time of menstrual recoveryDay 73±12Time to first menstruation after Hysteroscopic adhesiolysis
Recurrence rate of adhesionsDay 73±12The Presence of adhesions was determined at second-look hysteroscopy after Hysteroscopic adhesiolysis, and the recurrence rate of adhesions (%) = number of adhesion reoccurrence/total number in the group × 100%
Menstrual blood volumeDay 73±12, Day 100±10 , Day 180±30, Day 360±30Record and evaluate by Pictorial Blood Loss Assessment Chart (PBAC)
Pregnancy rate after operation 1yearDay 360±30Pregnancy rate (%) = number of pregnancies in the group/total number in the group × 100%
Duration of Menstrual recoveryDay 73±12, Day 100±10 , Day 180±30, Day 360±30Days of menstrual duration
