Brief summary: The clinical study with UMC119-06-05 is designed to investigate the safety in patients with mild to moderate knee osteoarthritis (KOA). This will be a dose escalation, open label, single-center study in adult with mild to moderate knee osteoarthritis. UMC119-06-05 is ex vivo cultured human umbilical cord tissue-derived mesenchymal stem cells product which is intended for treatment of knee osteoarthritis.

Detailed description: Knee osteoarthritis (KOA), also known as degenerative joint disease, is the most common type of arthritis diagnosed. KOA is typically the result of wear and tear and progressive loss of articular cartilage. The prevalence of the Knee osteoarthritis will continue to increase as life expectancy and obesity rises. Osteoarthritis is typically a progressive disease that may eventually lead to disability. The intensity of the clinical symptoms may vary from each individual. However, they typically become more severe, more frequent, and more debilitating over time.The intensity of the clinical symptoms may vary from each individual. However, they typically become more severe, more frequent, and more debilitating over time.

The rate of progression also varies for each individual. Common clinical symptoms include knee pain that is gradual in onset and worse with activity, knee stiffness and swelling, pain after prolonged sitting or resting, and pain that worsens over time. Treatment for knee osteoarthritis begins with conservative methods and progresses to surgical treatment options when conservative treatment fails. While medications can help slow the progression of RA and other inflammatory conditions, no proven disease-modifying agents for the treatment of knee osteoarthritis currently exist. Among the more innovative, experimental therapies, mesenchymal stromal cells (MSCs) are proposed as a novel therapy with potential in treatment of KOA.

Eligibility criteria: Inclusion Criteria:

1. Ambulatory subjects with osteoarthritis of the knee with symptoms for at least 3 months, that may be taking conservative therapy (e.g. oral anti-inflammatory medication), and/or undergoing physical therapy. In subjects with bilateral knee osteoarthritis, the more symptomatic knee will be the target knee.
2. Subjects of age between ≥40 through ≦ 90 years.
3. Subject diagnosed with knee osteoarthritis of grade II and III according to the Kellgren-Lawrence Grading Scale on the target knee.
4. Subject with joint pain equal or greater than 7 (total pain score 24 point) on the target knee assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
5. Subject or legal guardian is willing to provide written informed consent to participate in the study after reading the informed consent form and the information provided, and has had the opportunity to discuss the study with the investigator or designee.
6. Women of child-bearing potential should have a negative urine pregnancy test prior to administration of investigational product, and the subject must agree within at least 4 weeks after the study administration to use a double barrier method of birth control.UNLESS they meet the following criteria:(1) Post-menopausal: 12 months of natural (spontaneous) amenorrhea or 6 months of spontaneous amenorrhea with serum Follicle Stimulating Hormone (FSH) levels \> 40mIU/mL, OR; (2) 6 weeks post-surgical bilateral oophorectomy with or without hysterectomy.
7. If a male and heterosexually active with a female of childbearing potential, the subject must agree within at least 4 weeks after the study administration to use a double barrier method of birth control (or must have been surgically sterilized) and to not donate sperm.

Exclusion Criteria:

1. Subjects with body mass index (BMI) over 40.
2. Subjects with knee deformity (knee varus or valgus greater than 10 degrees) on the target knee.
