4. For the study knee, the average daily worst pain score over the 14 days prior to day 1 (ie, days -14 to day -1) must be 4.0 to 9.0. The 14-day average score will be derived from daily worst pain scores recorded in a diary for the study knee.
5. Stable knee pain in the study knee for = 6 consecutive months prior to visit 1. No evidence of abnormal mechanical symptoms such as locking or catching of the study knee per medical history or physical examination.
6. Body weight = 40 kg and = 150 kg with a body mass index (BMI) of 19 to = 40 kg/m2 inclusive.
7. For females of childbearing potential, a negative urine pregnancy test at screening, baseline, and on the day of the treatment (prior to the administration of the study medication) is required.
8. Must be ambulatory without assistive walking devices, able to perform usual daily activities, and agree to maintain the similar activity level throughout the course of the study.
9. Ability to follow study instructions and likely to complete all required visits.
10. Stable medical condition, in the investigator’s opinion.

Exclusion Criteria

1. Patient diagnosed with any condition suggestive of a secondary cause of knee OA including but not limited to knee trauma, articular fracture, major dysplasias or congenital abnormality, acromegaly, ochronosis, hemochromatosis, Wilson’s disease,or primary osteochondromatosis.
2. History of or current evidence of rheumatoid arthritis as diagnosed by ACR criteria, or history of prior synovial fluid analysis of the study knee showing a white blood cell count =2000 mm3 that is indicative of a diagnosis other than OA.
3. Presence of bursitis or tear of meniscus or ligament of the study knee, or history of significant knee injury to the study knee within 1 year of visit 1.
4. History of surgery in the study knee within 24 weeks prior to visit 1, or already planned surgery of the study knee such as, arthroplasty, arthroscopy inspection, or repair of knee ligaments.
5. Treatment with IA hyaluronic acid in the study knee within 24 weeks prior to visit 1.
6. Treatment with IA corticosteroid in any joint or intramuscular corticosteroid administration within 12 weeks prior to visit 1.
7. Concurrent chronic pain conditions such as back pain, hip pain (eg, disc herniation, peripheral nerve entrapment, multiple sclerosis), fibromyalgia that may interfere with assessment of the study knee. The study knee pain should be the predominant pain.
8. History or current diagnosis of gout or pseudogout with knee involvement.
9. History or current diagnosis of Reiter’s, Sjögren’s syndrome, psoriasis or systemic lupus erythematosus or other autoimmune diseases with joint involvement.
10. Patients at a high risk of joint infection complication (eg, infection of local skin, soft tissue and joint in the study knee, indwelling urinary catheter) or have immunocompromised conditions (eg, known HIV or organ transplant).
11. Evidence of abnormal coagulation status (eg, excessive tooth bleeding with brushing, abnormal bleeding time, partial thromboplastin time or prothrombin time) or patients with hemophilia or other blood diseases affecting coagulation (eg, aplastic anemia, leukemia, or under chemo-/radio-therapy).
12. Patients continue to take excluded analgesic medications after visit 2.
13. Patients with contraindications to the use of paracetamol (ie, rescue medication for this study).
14. History of severe, progressive, or current unstable medical conditions other than OA such as renal, hepatic, gastrointestinal, neurological, endocrine, metabolic, degenerative bone disorders, respiratory, and/or psychiatric disorder as determined by medical history, physical examination and /or laboratory tests.
15. History of severe cardiovascular diseases, stroke, recurrent seizures, frequent or severe allergic reactions to multiple medications.
16. Electrocardiogram (ECG) abnormality at screening that in the opinion of the investigator could increase risk associated with participation in the study.
17. Patients with an active malignancy of any type or a history of malignancy within the last 5 years (except basal cell carcinoma of the skin that has been excised at least 12 weeks prior to study start).
18. Have a history of substance abuse or dependence within the past year, excluding nicotine and caffeine.
