A Clinical Study to Evaluate the Safety and Efficacy of Q-Fix Trial in Chinese Patients

Summary

Protocol synopsis Title of Study: A Prospective, Randomized, Multi-Center Clinical Study to Evaluate the Safety and Efficacy of Q-Fix All-Suture Anchor in Arthroscopic Repair of Shoulder Soft Tissue in Chinese Patients

Study Design: Prospective, multicenter, comparative, randomized, concurrent control Study Type: Randomized Controlled Trial (RCT) Study Product: Q-Fix All-Suture Anchor Comparison Group Twinfix Ti Suture Anchor Study Purpose: The purpose of this study is to evaluate the safety and efficacy of Q-Fix All-suture Anchor in patients requiring the repair of soft tissue of shoulder who receive the arthroscopic repair of soft tissue using Q-Fix All-suture Anchor, when compared with the patients receiving the treatment with Twinfix Ti Suture Anchor. The result of this trial will be used for the Q-Fix All-suture Anchor registration in China.

Primary Objective: The primary objective of this study is to confirm that the clinical outcome of subjects receiving the treatment with Q-Fix All-suture Anchor is non-inferior to that of the subjects receiving the treatment with Twinfix Ti Suture Anchor during the same period, at 6 months after the repair of soft tissue of shoulder, taking the mean Constant score as efficacy endpoint.

Secondary Objective(s): The secondary objective of this study is to determine the safety and efficacy of Q-Fix All-suture Anchor at 12 months after repair of soft tissue of shoulder.

Statistical Rationale: The primary efficacy endpoint of this study is Constant score at 6 months after operation. The non-inferiority testing is performed for efficiency of primary efficacy endpoint; the test hypothesis is as follows:

Invalid hypothesis: H0: μ1-μ2 ≤ -δ Alternative hypothesis: H1: μ1-μ2 \> -δ Where, μ1 and μ2 are the mean Constant scores in the test and control group, respectively. δ is the non-inferiority margin, which is set to 10. The hypothesis will be tested by two-sided t-test at the alpha level of α=0.025 (one-tailed test). the A non-inferior test will be conducted on the Constant scores in the test and control groups. The 95% confidence interval for the difference between two groups will be calculated. If the lower limit of 95%CI for the efficiency difference between two groups is greater than -9, it is considered that the test group is non-inferior to the control group.

Sample Size: 128 (64 in each group) Number of Study Sites: Approximate 5 clinical sites Targeted Global Regions: China
