简要总结
This is a prospective, randomized, multi-site, safety and efficacy study in subjects with rotator cuff injuries.
Patients will fall into two categories: treatment group (12 subjects) and non-treatment or control group (six subjects). The treatment group will undergo a small liposuction procedure and receive rotator cuff repair treatment with an ultrasound-guided injection of 5cc adipose-derived stem cells (ADSCs) into the point of injury. The control group will receive a 5cc cortisone injection into the point of injury
详细描述
The primary objectives of this study were to evaluate the safety of adult Adipose-Derived Stem Cell (ADRC) injection into partial thickness rotator cuff tears as indicated through adverse event rate and efficacy of pain and function through Rand short form-36 questionnaire and ASES Shoulder Score health questionnaires.
The secondary objective of this study was to assess the efficacy of adult ADRC injection into partial thickness rotator cuff tears through MRIs pre-and post-injection for the therapeutics intent to treat a rotator cuff injury.
Patients enrolled on this study received either ADRC (i.e., investigational treatment group) or TAU (i.e., control group). The investigational treatment group underwent a small liposuction procedure and received rotator cuff repair treatment with an ultrasound-guided injection of 5cc ADRCs into the point of injury. The control group received a 5cc cortisone injection. All patients, regardless of treatment, were followed up as indicated on the schedule of events table in the clinical study protocol.
Two clinical trial sites (Sioux Falls, SD and Fargo ND) enrolled subjects in this study.

入选标准
- •Males and females 30-75 years of age.
- •Clinical symptoms consistent with a rotator cuff lesion including but not limited to pain, muscle weakness, or active-limited range of motion (AROM).
- •Subjects who have not responded to physical therapy treatments for at least six weeks.
- •Subjects with > 70% passive range of motion (PROM).
- •Diagnosed with >50% tear to supraspinatus muscle or < 5mm separation assessed by MRI.
- •Diagnosed with a partial-thickness rotator cuff tear
- •The ability of subjects to give appropriate consent or have an appropriate representative available.
排除标准
- •Age <30 or > 75
- •Insufficient amount of subcutaneous tissue to allow recovery of 50cc of lipoaspirate.
- •History of systemic malignant neoplasms within last 5 years.
- •History of local neoplasm within the last 6 months and any history of local neoplasm at site of administration.
- •Subject is receiving immunosuppressant therapy or has known immunosuppressive or severe autoimmune disease that requires chronic immunosuppressive therapy (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.).
- •Subjects who are known to be HIV positive
- •Patients who have received a corticosteroid injection in rotator cuff site within last 3 months
- •Severe arthrosis of the glenohumeral or acromioclavicular joint
- •Irreparable rotator cuff tear (including rotator cuff tear arthropathy)
- •Fatty atrophy above Grade 2 in affected shoulder
- •Previous shoulder surgeries in affected shoulder
- •History of tobacco use within the last 3 months
- •Any contraindications to MRI scan according to MRI guidelines, or unwillingness to undergo MRI procedures
- •Patients on an active regimen of chemotherapy
- •Patients with a documented history of liver disease or an ALT value >400
- •Allergy to sodium citrate of any "caine" type of local anesthetic
- •Patients pregnant or breast feeding
- •Subject is in the opinion of the Investigator or designee, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason. This includes completion of Patient Reported Outcome instruments.
- •Subject is currently participating in another clinical trial that has not yet completed its primary endpoint.
- •Subject is part of a vulnerable population who, in the judgment of the investigator, is unable to give Informed Consent for reasons of incapacity, immaturity, adverse personal circumstances or lack of autonomy. This may include: Individuals with mental disability, persons in nursing homes, children, impoverished persons, persons in emergency situations, homeless persons, nomads, refugees, and those incapable of giving informed consent. Vulnerable populations also may include members of a group with a hierarchical structure such as university students, subordinate hospital and laboratory personnel, employees of the Sponsor, members of the armed forces, and persons kept in detention.
- •Uncooperative patients or those with neurological/psychiatric disorders who are incapable of following directions or who are predictably unwilling to return for follow-up examinations.
