Intervention model description: Prospective, single-center phase I pilot study to evaluate the safety and tolerability of a single intra-articular injection of autologous bone marrow-derived MSCs in 16 subjects, 8 who have knee osteoarthritis and 8 who have a focal chondral defect in the knee.
Primary purpose: TREATMENT

Brief summary: Many patients with osteoarthritis of the knee fail non-operative measures and elect to have knee arthroplasty to improve their quality of life. If successful, intra-articular mesenchymal stem cell (MSC) injections into the knee may offer another viable non-operative treatment modality. Additionally, this modality may have reparative or regenerative potential, which could lead to the first treatment for osteoarthritis that treats the underlying disease as opposed to symptomatic control.

Additionally, there are no acceptable non-surgical treatments for focal chondral defects of the knee. Surgical treatments that do exist have diminished outcomes if performed on patients older than age 30-40 years. If successful, intra-articular MSC injections into the knee would represent the first non-operative treatment for focal chondral defects and also represent a potential option for treatment in patients over the age of 30-40 years.

This trial will be a prospective, single-center phase I pilot study to evaluate the safety and tolerability of a single intra-articular injection of autologous bone marrow-derived MSCs in 16 subjects, 8 who have knee osteoarthritis and 8 who have a focal chondral defect in the knee. Patients will undergo a bone marrow harvest procedure at the Dahms Clinical Research Unit (DCRU) of University Hospitals Cleveland Medical Center. MSCs will be isolated and expanded. After approximately 2-3 weeks, patients will return for an intra-articular injection of 50x106 MSCs Subsequent study visits will occur on post-injection day 7 and months 2, 6, 12, and 24. Safety of intra-articular injection of MSCs will be evaluated at study visits by interval history, physical examination and assessment of any adverse events that are observed/reported. Additionally, efficacy will be evaluated by having patients complete functional outcome measures including: Visual Analog Score (VAS) for pain, Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) Subjective Knee Form, and Lysholm Knee Scale. These will be completed at the pre-treatment visit and then repeated at the 2, 6, 12, and 24-month follow-up visits. Lastly, T1 rho and T2 mapping on magnetic resonance imaging (MRI) will be used to assess for improved cartilage quality after intra-articular injection of MSCs. An MRI will be obtained at the pre-treatment visit. At the 12 and 24 month follow up visit, additional MRIs will be obtained and analyzed to compare the pre-treatment MRI to post-treatment MRIs.


Eligibility criteria: Inclusion Criteria:

Knee Osteoarthritis Subjects

1. Male or female 18-60 years of age
2. Confirmed diagnosis of knee osteoarthritis based on clinical and radiographic findings
3. Unilateral chronic knee pain \>4 months
4. Imaging findings consistent with mild-moderate generalized cartilage degeneration (MRI chondropathy or radiographic changes)
5. Failed non-invasive modalities of treatment
6. Subjects must have the ability to understand and the willingness to sign a written informed consent document
7. For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of \<1% per year during the treatment period. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (\<12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of \<1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptive that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Period abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception

Focal Chondral Defect Subjects

Inclusion Criteria:

1. Male or female 18-60 year of age
2. Knee pain and/or effusion
3. Inability to continue or difficulty in participation in recreational or professional sport

5. Subjects must have the ability to understand and the willingness to sign a written informed consent document
6. For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of \<1% per year during the treatment period. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (\<12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of \<1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptive that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Period abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
