Brief Summary:
The study is a multicenter trial conducted to compare the effectiveness of an injection of a corticosteroid control to mesenchymal stem cell (MSC) preparations from autologous bone marrow concentrate (BMAC), adipose derived stem cells in the form of Stromal Vascular Fraction (SVF), and third party human mesenchymal stem cells manufactured from umbilical cord tissue (UCT) for the treatment of unilateral Knee Osteoarthritis (OA). The study will be conducted in 4 sites in the United States, and a total of 480 participants will be enrolled in this study.

Detailed Description:

Primary osteoarthritis is a debilitating disease characterized by extensive damage to the joints and excruciating pain leading to loss of activity and depression. Despite advances in diagnosis and relatively efficient control of nociception, to date, the quest for the development of a disease modifying osteoarthritis drug has proven unsuccessful. The potential of mesenchymal stem cells (MSCs) to inhibit inflammation while promoting healing makes them amenable for the treatment of various ailments ranging from cancer to genetic diseases. In orthopedic practice, autologous stem cell injections are performed to alleviate the pain associated with osteoarthritis. A serious gap in knowledge remains whether the currently used cellular treatments are beneficial in the long term and if one cell therapy outperforms another.

The most popular form of autologous MSC therapy has been through the use of autologous bone marrow concentrate (BMAC). The rationale is that when a sample of bone marrow aspirate (BMA) is collected and the components that are not beneficial to the joint are filtered out (i.e. red blood cells, neutrophils, etc.) the remaining concentrate (MSCs, platelets, interleukins, etc) can have a "healing" effect on the environment in which it is injected. However it is still unknown as to how effective BMAC is for treating orthopedic conditions compared to other MSC procedures and the most important components of the BMAC mixture that could aid patients suffering from osteoarthritis.

Adipose tissue has been found to have a large amount of MSCs versus that in bone marrow. These cells are currently being used in a variety of clinical research studies within the regenerative medicine field. Through a tissue process which includes washing and centrifuging, the cellular components can be extracted as a cell pellet, which is also known as stromal vascular fraction (SVF). Adipose derived SVF is obtained via liposuction, or the removal of adipose tissue via a suction method.

Although the use of various stem cell preparations for knee osteoarthritis has become increasingly prevalent, well-designed studies with conclusive proof of comparative effectiveness and identification of the optimal cell source and "dose" have not been performed. This study is the first randomized study comparing three types of cellular treatments to corticosteroids. The main objective of the study is to identify a superior source of stem cells for the treatment of osteoarthritis and validate its advantages over corticosteroid injections as the traditional gold standard treatment.

Participants will be randomized study arms with different types of MSCs (bone marrow derived MSC, adipose derived MSC, and umbilical cord tissue MSC) and then will be further randomized to receive an injection of the MSC type they were initially assigned to or corticosteroid. Participants randomized to bone marrow derived MSC or adipose derived MSC will undergo a procedure (bone marrow aspiration or liposuction). Participants will be blinded to whether they receive the MSC or corticosteroid injection.

Arm Intervention/treatment
Experimental: Bone Marrow Derived MSCs
Participants randomized to this arm will undergo bone marrow aspiration and then will be further randomized to receive a standard orthobiologic injection into the knee joint of autologous bone marrow concentrate (BMAC).
Biological: Bone Marrow Derived MSCs
Autologous bone marrow concentrate (BMAC) is a standard orthobiologic injection for knee osteoarthritis.The procedure involves harvesting of bone marrow aspirate (BMA) from the posterior superior iliac spine (PSIS) and then following centrifugation in an FDA approved device (EmCyte GenesisCS Pure BMAC®-60 ml) will be injected back into the knee joint. All injections will be made via ultrasound guidance using a standard approach.

Experimental: Adipose-derived MSCs
Participants randomized to this arm will undergo small volume lipoplasty, and then will be further randomized to receive an injection into the knee joint of adipose-derived stromal vascular fraction (SVF).
Biological: Adipose-derived MSCs
Adipose-derived Stromal Vascular Fraction (SVF) will be obtained from a mini lipoaspirate. The lipoaspirate will then be enzymatically digested to produce a SVF that will be injected into the knee joint. All injections will be made via ultrasound guidance using a standard approach.

Experimental: Umbilical Cord Tissue (UCT) MSCs
Participants randomized to this arm will receive an injection into the knee joint of cryopreserved doses of umbilical cord tissue MSCs.
Biological: Umbilical Cord Tissue (UCT) MSCs
Cryopreserved doses of umbilical cord tissue MSCs will be used. These MSCs were cryopreserved at P2 culture in plasmalyte A + 5% human serum albumin in 5 finger cryobags containing 20 million cells in 4 mL and stored under liquid nitrogen until shipment. Cells will be transported in a dry shipper and thawed at the study sites. The dose of MSCs will be aspirated from the cryobag into a sterile syringe and directly injected into the knee. All injections will be made via ultrasound guidance using a standard approach.

Active Comparator: Corticosteroid Injection
Participants randomized to the bone marrow derived MSC, adipose-derived MSC, or umbilical cord tissue MSC study arms will be further randomized within the arm in a 3:1 ratio to receive either MSCs derived from the study arm of the initial randomization or a corticosteroid (CS) injection. Participants randomized to the control group will receive an injection of corticosteroid into the knee joint.
Drug: Corticosteroid injection
The corticosteroid injection is prepared by mixing 1cc of 40mg/dL depomedrol and 6cc of normal saline in a 10cc syringe will be made into the knee joint. All injections will be made via ultrasound guidance using a standard approach.

Primary Outcome Measures :
  1. Change in Visual Analog Pain Scale (VAS-pain) Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    Pain assessment will be done using the Visual Analog Pain Scale (VAS-pain). The VAS-pain is self-completed by the participant. The respondent is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the participant's mark, providing a range of scores from 0-100. The recommended cut points for VAS are: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).

  2. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) - Pain Subscale Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The pain subscale has 9 items and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. Scores are transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The KOOS has 42 items across all subscales and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. The sum of subscale scores is transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

  2. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) - Symptoms Subscale Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The symptoms subscale has 7 items and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. Scores are transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

  3. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) - Activities of Daily Living (ADL) Function Subscale Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The ADL function subscale has 17 items and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. Scores are transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

  4. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) - Sports and Recreation Function Subscale Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The sports and recreation subscale has 5 items and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. Scores are transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

    The KOOS questionnaire assesses the participant's opinion about their osteoarthritis and associated problems. It consists of 5 subscales; pain, symptoms, activities of daily living (ADL) function, sport and recreation function, and knee related quality of life (QoL). The QoL subscale has 4 items and response options are given on a 5-point Likert scale where 0 = no problems and 4 = extreme problems. Scores are transformed to a scale ranging from 0 to 100 with 0 indicating extreme symptoms and 100 indicating no symptoms.

  6. Change in EuroQuality of Life (EQ-5D-3L) Index Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The EQ-5D-3L survey measures the severity of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The participants will be asked to answer questions regarding these measures and to indicate their current experience on a scale from 1 to 3 (1 being "no problem" and 3 being "most extreme problem"). A sixth item asks participants to rate their current heath from 0 (worst imaginable) to 100 (best imaginable). The answers to these question are converted into an index value based on the country respondents live in. Health state index scores typically range from less than 0 to 1, where 0 is a health state equivalent to death and 1 is perfect health.

  7. Change in Patient-Reported Outcomes Measurement Information System (PROMIS 29) Score [ Time Frame: Baseline, 1 month, 3 months, 6 months, 9 months, 12 months ]
    The PROMIS-29 assesses seven health domains: physical function, anxiety, depression, fatigue, sleep disturbance, pain interference, and ability to participate in social roles and activities. Each of the seven domains has four questions which are scored on a five-point Likert scale. The PROMIS-29 scales are scored using a T-score metric method available at the Assessment Center website (http://assessmentcenter.net). A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Scores higher than 50 indicate more of the specific scale's construct, which may indicate a desirable or an undesirable outcome.
