Inclusion criteria

* Adults aged 19 years or older * Shoulder pain lasting for at least 3 months * A pain visual analogue scale (VAS) score of 4 or greater * Inadequate response to sufficient conservative treatment for at least 3 months, such as medication, injection therapy, physical therapy, or exercise therapy * Partial-thickness rotator cuff tear confirmed by ultrasonography or magnetic resonance imaging (MRI) * No restrictions on participation in clinical trial procedures, including hospitalization

Exclusion criteria

* Receipt of subacromial injection therapy in the affected shoulder within the past 3 months * History of rotator cuff surgery on the affected shoulder within the past 6 months * Previous treatment with a stem cell therapy for the shoulder * Presence of any of the following shoulder conditions: full-thickness rotator cuff tear, obvious isolated acromioclavicular joint arthropathy, or a clear history of trauma to the shoulder joint within the past 3 months * Radiologic findings suggestive of or consistent with any of the following: malignancy, severe glenohumeral osteoarthritis, bony abnormalities causing narrowing of the subacromial space, or clear evidence of acute traumatic rotator cuff injury * Presence of symptomatic cervical spine disease * Patients with polyarthritis, infectious arthritis, rheumatoid arthritis, or fibromyalgia * Clinical trial subjects with neurological deficits * Pregnant or breastfeeding women * Unwillingness to use an effective method of contraception during participation in the clinical trial * Presence of any serious disease that may affect participation in this clinical trial, including cardiovascular, renal, hepatic, endocrine, or neoplastic disease * Inability to understand the questions used to assess the subject's condition, including the visual analogue scale (VAS), or communication difficulties due to psychiatric illness * Unwillingness to participate in the clinical trial or difficulty in complying with follow-up visits according to the study schedule * Participation in another clinical trial within 3 months prior to enrollment in this clinical trial * Any other condition that, in the opinion of the investigator, makes the subject unsuitable for participation in this clinical trial

Design outcomes

Primary

MeasureTime frameDescription
Changes in the size of rotator cuff tears determined by MRI6monthsThe location, width (AP size), length (ML size), and depth of the rotator cuff tear will be measured on oblique coronal, axial, and sagittal MRI images where the tear is most clearly visualized. The same measurements will be performed on the corresponding planes after administration of the investigational product and compared with those obtained before administration.

Secondary

MeasureTime frameDescription
Shoulder pain and disability index(SPADI) Score6monthsThe Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities. The pain dimension consists of five questions regarding the severity of an individual's pain. Functional activities are assessed with eight questions designed to measure the degree of difficulty an individual has with various activities of daily living that require upper-extremity use. The minimum value is 0 and the maximum value is 10. "0" means no pain and "10" means the worst pain imaginable in the pain section. "0" means no difficulty and "10" means so difficult it requires help in the pain section.
Constant-Murley score6monthsThe Constant score assesses pain, function, ROM, and strength. Pain is allotted a maximum of 15 points, activities of daily living (function)20 points, ROM 40 points, and strength 25 points. The component scores are summated to achieve a maximum possible total score of 100.
Visual Analog Scale(VAS) pain6monthsUsing a ruler, the score is determined by measuring the distance (mm) on the 100mm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
Location and size of the rotator cuff tear assessed by arthroscopy6months
Histological Evaluation of Tendon Tissue6monthsIf tendon regeneration at the lesion site is confirmed by arthroscopic examination before and after administration of the investigational product, a tissue sample approximately 2 mm in diameter will be collected from the regenerated area and evaluated using the modified Astrom and Movin scoring system.
Short tandem repeat (STR) evaluation of tendon tissue6monthsSTR testing will be performed using a portion of the collected tendon tissue. The results will be compared with those of the investigational product and the clinical study participant's blood to evaluate the origin of the regenerated tendon tissue.
Amount and frequency of rescue medication use6months
Adverse events6months
HeightVisit 1The investigator will perform physical examinations according to the clinical study schedule, based on medical judgment. Height will be measured only at Visit 1. Height will be measured in centimeters
Weight6monthsThe investigator will perform physical examinations at each visit according to the clinical study schedule, based on medical judgment. Body weight will be measured in kilograms at each visit.
Systolic and Diastolic blood pressure6monthsThe investigator will check systolic and diastolic blood pressure at each visit according to the clinical study schedule, based on medical judgment.systolic and diastolic blood pressure will be measured in a seated position.
Pulse rate6monthsThe investigator will check pulse rate at each visit according to the clinical study schedule, based on medical judgment. Pulse rate will be measured in a seated position.
Complete blood count6monthsWhenever possible, blood samples will be collected after the participant has fasted for at least 9 hours. During the fasting period, participants should not consume any food or beverages other than water. \- WBC, RBC, hemoglobin, hematocrit, platelets, and differential count
Serum chemistry test6months\- general: glucose, BUN/creatinine, total protein, albumin, total bilirubin, AST/ALT, ALP, γ-GTP, CK, ESR, CRP Whenever possible, blood samples will be collected after the participant has fasted for at least 9 hours. During the fasting period, participants should not consume any food or beverages other than water.
Urinalysis6months\- pH, specific gravity, protein, glucose, bilirubin, blood, ketone, and microscopic examination
Alloimmune test6monthsClinical study participants will visit the study site at Visit 2 (treatment) and Visit 3 (exploratory efficacy and safety assessment) to undergo alloimmune testing. * Antigen test: HLA-A, HLA-B, HLA-DR * Antibody test: PRA-I, PRA-II If a positive response is observed in the PRA test, the following additional tests will be performed: \- HLA Single Ag I, HLA Single Ag II
