Brief Summary:
Osteoarthritis (OA) is one of the most common diseases affecting the joints, usually those that are weight bearing such as the knees. OA is considered to be a disease of the cartilage in the joints even though it involves the whole joint, including the bone and synovium (thin lining of the joints which produces synovial fluid). With time, more and more of the cartilage is destroyed by the disease with inflammation commonly occurring.
AS902330 is expected to increase the production and development of specific bone cells: chondrocytes and osteoblasts (cells that produce and maintain bone and cartilage). This is expected to lead to repair and generation of the cartilage, and a narrowing of the space width between the knee joints in a selected region of the knee cartilage. The purpose of this study is to see how safe treatment with AS902330 is, and to evaluate its effect on the knee cartilage. In addition, the study will also measure the effects of AS902330 in the blood, which reflect disease activity.

Primary Outcome Measures :
- Change in cartilage thickness in the medial femoro-tibial compartment of the target knee joint, assessed by MRI [ Time Frame: 6 and 12 months after first injection ]
- Nature, incidence and severity of local and systemic treatment-emergent adverse events (TEAEs) [ Time Frame: MAD Cohorts: 1 year + 1 month; SAD Cohorts: 4 Weeks ]
- Proportion of subjects experiencing AIRs defined as increase of pain by 30mm on a 100mm visual analogue scale (VAS) associated with a self-reported synovial fluid effusion within 3 days following i.a. injection [ Time Frame: MAD Cohorts: Week 1, 2, 3, 13 14 and 15 (injections weeks); SAD Cohorts: Week 1 ]
- Laboratory assessments, including blood chemistry, hematology, urinalysis, and ECG [ Time Frame: MAD Cohorts: Week 0, 4, 13, 17, 52; SAD Cohorts: Weeks 0 & 4 ]
Secondary Outcome Measures :
- Change in cartilage thickness in the medial femoro-tibial compartment of the target knee joint, assessed by MRI [ Time Frame: 52 Weeks ]
- Change in total cartilage volume and thickness in the other compartments of the target knee joint, assessed by MRI [ Time Frame: 52 Weeks ]
- Change over time of structural as well as compositional parameters of the knee joint (e.g. cartilage and bone), evaluated by MRI [ Time Frame: 52 Weeks ]
- Change in WOMAC (Western Ontario MacMaster Osteoarthritis Questionaire) total score in the target knee from 5-point Likert scales [ Time Frame: 52 Weeks ]
- Change in WOMAC Function and Pain index scores in the target knee [ Time Frame: 52 Weeks ]
- Change in osteoarthritis (OA) pain in the target knee on a 100mm visual analogue scale (VAS) [ Time Frame: 52 Weeks ]
- Change in JSW in the target knee by x-ray [ Time Frame: 52 Weeks ]
- Presence of anti-AS902330 antibodies [ Time Frame: 52 Weeks ]
- Blood levels of AS902330 [ Time Frame: 52 Weeks ]
- MRI at 3 months, score on WOMAC questionnaire at 3, 6 and 12 months. [ Time Frame: 6 days ]

Criteria
Inclusion Criteria:
- Male or female >= 40 years of age; females must be postmenopausal or surgically sterile
- Established diagnosis of primary femoro-tibial OA of the target knee by standard American College of Rheumatology Criteria for at least six months (clinical AND radiological criteria)
- Radiological disease stage 2 or 3 (i.e., clear evidence of OA, but not most advanced disease) in the target knee according to the Kellgren-Lawrence grading of knee OA
- No major knee surgery (e.g., partial or total knee replacement, interventional arthroscopy) in the target knee planned for at least 12 months after first injection of the study drug
- Documented need for symptomatic PRN (as needed)-treatment for OA in the target knee with systemic non-steroidal anti-inflammatory drugs (NSAIDs) and/or other analgesics.
- Total WOMAC score between 24 and 72 (out of 96, corresponding to mild, moderate, or severe, but not extreme OA symptoms) for the target knee while on oral symptomatic treatment at baseline
- Full understanding of the requirements of the study and willingness to comply with all study visits and assessments
- Patients must have read and understood the informed consent form, and must have signed it prior to any study-related procedure
Exclusion Criteria:
- any condition, including laboratory findings and findings in the medical history or in the pre-study assessments, that in the opinion of the Investigator constitutes a risk or contraindication for participation in the study or that could interfere with the study objectives, conduct or evaluation
- clinically significant abnormal hematology (hemoglobin, leucocytes, and platelets), or blood chemistry values (aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, and creatinine

- any known active infections, including suspicion of intra-articular infection and/or infections that may compromise the immune system such as HIV, Hepatitis B or Hepatitis C infection
- history of sarcoma and/or of other active malignancy within five years, except adequately treated basal cell or squamous cell carcinoma of the skin
- signs and symptoms suggestive of transmissible spongiform encephalopathy
