Use of Autologous Bone Marrow Aspirate Concentrate in Painful Knee Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
The overall goal of this study is to develop regenerative cell therapy for use in patients with osteoarthritis (OA). The primary objective of this proposal is to conduct a pilot study that assesses the safety and feasibility of using concentrated bone marrow aspirate containing MSC to treat patients with painful knee OA.

Detailed Description
-----------------
Patients with symptomatic mild to moderate bilateral knee osteoarthritis will be candidates for this pilot study. Baseline data includes radiographs, MRI imaging, clinical data on knee pain and analysis of synovial fluid inflammatory markers. Bone marrow will be aspirated from the patient's iliac crests and the cellular rich portion will be concentrated. Randomly, one knee will be injected with the bone marrow concentrate. The contralateral knee will be injected with only sterile saline for placebo. Follow-up analysis of synovial fluid will be at one week and 6 months after injection; clinical data will be obtained at 3, 6 and 12 months and MRI imaging will be performed at 6 months after injection, with repeat radiographs at 12 months

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Autologous bone marrow concentrate<br>Subjects with symptomatic mild to moderate bilateral knee osteoarthritis will be enrolled in this study. Bone marrow will be aspirated from the patient's iliac crests and the cellular rich portion will be concentrated. Randomly, one knee will be injected with the autologous bone marrow aspirate concentrate. The contralateral knee will be injected with only sterile saline for placebo. | Drug: Autologous Bone Marrow Aspirate Concentrate<br>* Autologous Bone marrow aspirate will be concentrated using Magellan Cell Separator and stem cell kit according to the Standard Operating Procedures is to be injected in the treatment knee. 5ml of treatment cells will be combined with 10 ml of previously separated platelet poor bone marrow plasma and used for injection under ultrasound guidance into one of the subject's painful knees.<br>|
| Placebo Comparator: Placebo<br>Subjects with symptomatic mild to moderate bilateral knee osteoarthritis will be enrolled in this study. Bone marrow will be aspirated from the patient's iliac crests and the cellular rich portion will be concentrated. Randomly, one knee will be injected with the bone marrow concentrate. The contralateral knee will be injected with only sterile saline for placebo. | Drug: Sterile saline<br>* Bacteriostatic 0.9% sodium chloride, preservative free manufactured by Hospira will be injected into the control knee.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Subjects with Adverse Reactions to Concentrated Mesenchymal Stem Cells (MSCs) | Occurrence of adverse reactions to concentrated MSCs from bone marrow aspiration injected into knee joints. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Knee Cartilage | Knee cartilage status will be measured prior to injection, at 6 months following injection, and at 12 months following injection. The cartilage will be measured by MRI at baseline and 6 months using MRI and cartilage sequencing techniques, and knee radiographs at 12 months. | baseline, 6 months, 1 year |
