Fat cell injection for arthritis? small study ends early

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Ankle pain for at least 6 months, despite conservative treatment or inability to tolerate the side effects of medications 3. Normal activity level, not bedridden or confined to a wheelchair, able to walk 30 meters without the aid of a walker, crutches or cane Hip Cohort: 1\. Hip OA diagnosed on x-ray and/or Magnetic Resonance Imaging (MRI) (Tӧnnis grade 1, 2, or 3) Knee Cohort: 1. Kellgren-Lawrence system of Grade II, III, or IV 2. Subject may have concomitant patellofemoral but they must have stage II or higher generalized knee OA Shoulder Cohort: 1.

Subjects who have failed standard non-surgical management of their shoulder arthritis who would benefit from a shoulder arthroplasty. Failed medical management will be defined as persistent pain and disability despite adequate standard non-operative management for 6 months. Medical management will be defined as: 1. The use of drugs including analgesics and non-steroidal anti-inflammatory drugs 2. Activity modification Wrist Cohort: 1\. Clinical symptoms consistent with wrist OA Exclusion Criteria- ALL Cohorts: 1. Subject cannot meet any of the exclusion criteria listed of the targeted joint cohort 2.

Oral, injected or implanted hormonal contraceptive, barrier methods (condom or diaphragm with spermicide), intrauterine device, surgical sterilization, transdermal delivery, congenital sterility or sexual abstinence are considered acceptable forms of birth control. If sexually active, the subject must have been using one of the accepted birth control methods at least one month prior to study entry. 8.

Insufficient amount of subcutaneous tissue to allow recovery of at least 100mL of lipoaspirate 12. Diagnosed musculoskeletal cancer or any diagnosed cancer, other than musculoskeletal if not on long term remission (e.g. at least 5 years or negative biopsy at last exam), except basal cell carcinoma 13. Have received chronic (more than 7 consecutive days) treatment with systemic corticosteroids at a dose equivalent to prednisone ≥ 10 mg/day within 14 days prior to an injection procedure. 14. Subject is currently participating in another clinical trial that has not yet completed its primary endpoint. (Nonintervention observational studies are not exclusionary.) 15. History of, or ongoing, autoimmune disorder that requires treatment with an immunosuppressive medication 16. Subjects who have a documented history or presence of inflammatory arthritis, rheumatoid arthritis, and sepsis in the treatment site 17. History of bleeding disorders or inflammatory joint disease 18. Inability to hold anti-platelet therapy according to treating provider prior to procedure 19. Any medical condition that could preclude participation in the study in the opinion of the investigator 20. Active workers' compensation case in progress with the targeted joint 21. Daily opioid use for the 3 months prior to screening or anticipated daily use while participating on study 22. Psychiatric disorder that may prevent participation in the study in the opinion of the investigators 23. A positive screen for human immunodeficiency virus (HIV) by antibodies or nucleic acid test 24. Has a known active Hepatitis B (e.g. HBsAg reactive) or Hepatitis C (e.g. HCV RNA \[qualitative\] is detected) 25. Allergy to sodium citrate of any "caine" type of local anesthetic 26. Hemoglobin less than 10g/dL at the time of screening 27. Leukocytes \<3,000/µL; neutrophils \<1,500/µL; lymphocytes \<800/µL; platelets \<100,000/µL at the time of screening 28. Subjects with a known diagnosis of osteoporosis 29. Diagnosis of liver disease as defined by alanine aminotransferase (ALT) \>2x the upper limit of age-determined normal (ULN) or total bilirubin \> 1.5x ULN Ankle Cohort: 1. Lower leg trauma in a location other than within the ankle 2. Arthroscopy or open surgery of the ankle joint within 6 months of screening. 3. Extreme obesity, as defined by National Institutes of Health (NIH) Clinical Guidelines Body Mass Index (BMI \> 40) 4. Any condition other than OA of the ankle joint which, in the opinion of the investigator, affects their ability to ambulate to a sufficient degree to interfere with the assessment of the safety and treatment effects of the study injection. Hip Cohort: 1. Evidence of hip dysplasia (centre edge angle less than 20⁰) 2. Previous fracture trauma to the affected hip requiring medical or surgical treatment 3.
