Study Details

Study Description

Brief Summary

The study is a multicentered, randomized, double-blinded, placebo-controlled study conducted on the unilateral knee of 120 patients. The study compares the effectiveness of an injection of a mesenchymal stem cell preparation from autologous bone marrow aspirate (BMA) to a corticosteroid control for knee osteoarthritis. WOMAC, VAS pain scores, and MRI will be used for assessment. The study will be conducted at 3 sites in the United States.

Detailed Description

Osteoarthritis (OA) is the most common form of arthritis in the knee that affects millions of adults throughout the world and is the leading cause of disability. It is a degenerative type of arthritis that occurs most often in patients, as the cartilage in the knee joint gradually wears away. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone and produce painful bone spurs. The patient experiences pain that worsens over time.

Although current surgical therapeutic procedures to cartilage repair are clinically useful, they cannot restore a normal articular surface, and in many cases, resulted in the growth of inferior quality fibrocartilage. Therefore, techniques and practices have been developed to collect minimally manipulated bone marrow aspirate (BMA), that contains Bone Marrow Derived Mesenchymal Stem Cells (BMDMSCs) and other endogenous acellular components, from knee OA patients for autologous transplantation in the treatment of their knee OA.

Participants will be randomized to study arms to receive a BMA injection to the intra-articular knee, subchondral knee, both intra-articular and subchondral knee, or to receive a corticosteroid injection to the knee. A corticosteroid injection is currently the standard of care for osteoarthritis patients having knee pain. All participants will undergo a procedure. Participants will be blinded as to whether they receive a BMA injection or a corticosteroid injection.

Outcome Measures

Primary Outcome Measures

Change from Baseline Western Ontario McMaster University Osteoarthritis Index (WOMAC) at 3 months [3 months]
The Western Ontario and McMaster Universities Osteoarthritis Index is a widely used, proprietary set of standardized questionnaires used by health professionals to evaluate the condition of patients with osteoarthritis of the knee and hip, including pain, stiffness, and physical functioning of the joints. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. A sum of the scores for all three subscales gives a total WOMAC score. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations. The minimum clinically important difference (MCID) for this parameter is ≥ 10.

Change from Baseline Visual Analog Score (VAS) at 3 months [3 months]
The pain VAS is a unidimensional scale of pain that is widely used and well validated in diverse groups of adult patients.

Magnetic Resonance Imaging (MRI) Evaluation [Baseline and 12 months]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the inside of the body.

Normal ECG.
Individuals 18 to 80 years old that have knee Osteoarthritis.
X-rays that demonstrate OA with the Kellgren-Lawrence grading scale of 2, 3 or 4 in at least one compartment of the knee either or both knees. Only subjects that have a single symptomatic knee will be enrolled.
No significant Medial Collateral Ligament (MCL) or Lateral Collateral Ligament (LCL) tear or laxity. (A significant LCL and MCL laxity or tear would be determined on clinical exam if there is no endpoint on valgus or Varus stress physical exam. Upon review of the MRI, NGRM will only treat subjects with no grade 2 or grade 3 ligamentous sprains [LCL, MCL, Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL)]. Next Generation Regenerative Medicine (NGRM) will treat subjects with degenerative meniscal changes in tears but no acute or large bucket handle tears.)
No significant meniscal tear. (i.e. bucket handle) (A positive McMurrays test on clinical exam indicates a significant meniscal tear. The subjects will also be getting a baseline MRI that will help delineate any further ligament injuries that may disqualify a subject.)
Subjects who have had the benefit of standard of care (SOC) treatment (activity modification, weight loss, physical therapy, anti-inflammatory medications, or injection therapy) before receiving experimental therapy. However, subjects cannot have had the benefit of standard of care treatment at less than 3 months before receiving experimental therapy. Enroll subjects who have demonstrated failure or are intolerant to SOC treatment. The time frame prior to screening when failure of conservative treatment would have occurred will be one year of symptoms and failure of conservative treatment which includes physical therapy, nonsteroidal anti-inflammatory medicine, cortizone injections, or hyaluronic acid injections.
Treatment failure is indicated by Subjects having symptoms of knee pain, swelling, and trouble with activities for at least 4 to 6 weeks. Subjects would only be enrolled if they fail conservative treatment. Usually physical therapy is administered initially for 6 weeks along with an NSAID medication. If that fails, which means that pain and swelling and disability continue, then injection therapy with corticosteroid or hyaluronic acid (HA) is given. Usually the injection is followed up in 6 to 8 weeks post-injection. If that fails, then Orthobiologics will be discussed (at about 4 to 6 months after treatment).
The subject must fail at least two conservative treatments, which could include physical therapy and NSAIDs, or physical therapy and injections, or NSAIDs and injections.
Subjects must have WOMAC and VAS scores of ≥30 and ≥4, respectively at least 2 weeks prior to enrollment.
Male and female subjects of reproductive potential must agree to refrain from sexual activity or use effective birth control for a duration of one week before and three months after initiation of treatment with either active treatment modality.
Subjects with basal cell, in situ carcinoma, or remote history (i.e., > 3 years ago) history of low-grade cancers (e.g., breast) that were effectively treated may be included.

Exclusion Criteria:

Tibia on femur subluxation greater than 1mm. Varus or valgus number greater than 9°.
