Clinical Trial Summary

Subjects received perioperative hAMSC treatment in order to accelerate the healing of the surgically repaired rotator cuff and increase the mechanical properties of the tendon, according to inclusion and exclusion criteria (see below). Each patient will undergo post-operative follow-up at 6 weeks, 6 months and 12 months after the surgery. This will include a visual analogue score for pain (VAS), a questionnaire for the subjective Constant shoulder score, and the subjective questions of the University of California (UCLA) score. Preoperative and postoperative MRI at 12 months will be done to evaluate the quality of the rotator cuff repair.

Description:

Eligible patients will undergo an arthroscopic rotator cuff repair augmented by mesenchymal stem cells (MSCs). The primary objective of the trial is to assess the safety and tolerability of autologous mesenchymal stem cells treatment applied during arthroscopic rotator cuff repair.

The condition of the patient will be monitored throughout the study. At each visit, adverse events (AEs) will be elicited using a standard non-leading questions. In addition, any signs or symptoms will be observed. All AEs will be collected as:

• patient's positive response to questions about their health

• symptoms spontaneously reported by the patient

• clinically relevant changes and abnormalities observed by the Investigator (e.g. local and systemic tolerability, clinically significant laboratory measurements confirmed by repeated measurement, results of physical examinations).

Clinical improvement will be measured by clinical outcome scores (Constant shoulder score and UCLA Shoulder rating scale) at 6 weeks, 6 months and 1 year after the surgery. MRI (Magnetic Resonance Imaging) findings made preoperatively and at 12 months (1 year) after operation will be evaluated.

During the indication visit, patient's history will be taken and preoperative MRI evaluated. Written consent form will be collected from the patient after detailed education of the patient by the investigator.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety: To assess the occurrence of adverse events of treatment by hAMSC - systemic reactions.	Safety and tolerability of hAMSC treatment applied during the surgical rotator cuff repair will be recorded - systemic reactions including allergic reaction or sepsis at Visits I through VI.	1 year
Primary	Safety: To assess the occurrence of adverse events of treatment by autologous mesenchymal stem cells - local reactions.	Safety and tolerability of autologous mesenchymal stem cells treatment applied during the surgical rotator cuff repair will be recorded - local reactions including pain, bleeding, local infection at Visits I through VI.	1 year
Secondary	Efficacy: To evaluate the effect of hAMSCs applied during arthroscopic rotator cuff repair - Visual Analogue Score (VAS)	The efficacy analysis will be evaluated by comparing pre- and post-treatment rotator cuff function measured by changes in Visual Analogue Score (VAS) (meter-shaped scale; in mm) at Visits II, IV, V, and VI.; VAS is a self-report measure consisting simply of a 10 centimeter line with a statement at each end representing one extreme of the dimension being measured (most often intensity of pain). The respondent gives their indication with a pen mark on the line corresponding to their answer, e.g. the present pain level.	1 year
Secondary	Efficacy: To evaluate the effect of hAMSCs applied during arthroscopic rotator cuff repair - Constant Shoulder Score	The secondary efficacy analysis will be evaluated by comparing pre- and post-treatment rotator cuff function by changes in Constant Shoulder Score (points) at Visits II, IV, V, and VI.; Measurements: Pain, Activities of daily living, Range of movement (forward flexion, abduction, external rotation, internal rotation), Power.; Less points (out of 100) means more severe condition.	1 year
Secondary	Efficacy: To evaluate the effect of hAMSCs applied during arthroscopic rotator cuff repair - UCLA Shoulder Rating Score	The secondary efficacy analysis will be evaluated by comparing pre- and post-treatment rotator cuff function by changes in UCLA Shoulder Rating Score (points) at Visits II, IV, V, and VI.; Measurements: Pain, Function, Active forward flexion, Strength of forward flexion (manual muscle-testing), Satisfaction of patient.; Less points (out of 35) means more severe condition.	1 year
Secondary	Efficacy: To evaluate the effect of hAMSCs applied during arthroscopic rotator cuff repair - MRI imaging - Continuation / discontinuation of the rotator cuff	The secondary efficacy analysis will be evaluated by comparing pre- and post-treatment rotator cuff function which measured by MRI imaging (preoperative and at Visit VI) to evaluate the quality of the rotator cuff repair.; Following finding will be recorded: Continuation / discontinuation of the rotator cuff; preoperatively - confirmation of complete unilateral rotator cuff tear; 1 year after the treatment (Visit VI) - the quality and extent of rotator cuff repair - no recovery/partial recovery/full recovery	1 year
Secondary	Efficacy: To evaluate the effect of hAMSCs applied during arthroscopic rotator cuff repair - MRI imaging - Fatty degeneration	The secondary efficacy analysis will be evaluated by comparing pre- and post-treatment rotator cuff function which measured by MRI imaging (preoperative and at Visit VI) to evaluate the quality of the rotator cuff repair.; Following finding will be recorded: - Amount of fatty degeneration - percentage of fatty infiltration of the cross sectional area of supraspinatus or infraspinatus assessed on the most lateral image on which the scapular spine is in contact with the scapular body,	1 year
