Eligibility Criteria

Inclusion Criteria

•Males or females in the age 20 - 70 years (both inclusive)
•Radiographic evidence of grade 2 to 3 osteoarthritis based on the Kellgren and Lawrence radiographic entry criteria.
•History of primary idiopathic osteoarthritis of the knee characterized by pain which requires intake of analgesics.
•Self-reported difficulty in at least one of the following activities attributed to knee pain: lifting and carrying groceries, walking 400 metres, getting in and out of a chair, or going up and down stairs.
•Patients who have been on stable medication for the past three months.
•Patients who have not received intra articular steroids or hyaluronan within the last three months.
•Female patients of childbearing age must be willing to use accepted methods of contraception during the course of the study
•Ability to provide written informed consent.

Exclusion Criteria

•Prior or ongoing medical conditions (e.g., concomitant illness, psychiatric condition, alcoholism, drug abuse), medical history, physical findings, ECG findings, or laboratory abnormality that, in the investigator's opinion, could adversely affect the safety of the subject, makes it unlikely that the course of treatment or follow-up would be completed, or could impair the assessment of study results.
•History of surgery, including arthroscopy, or major trauma to the study joint in the previous 12 months
•Signs of active study joint inflammation including redness, warmth, and/or, if qualifying with osteoarthritis of the knee, a large, bulging effusion of the study knee joint with the loss of normal contour of the joint at the screening visit or at the baseline examination
•Infections in or around the knee.
•Patients awaiting a replacement knee or hip joint
•Patients with other conditions that cause pain
•Significantly incapacitated or disabled and would be categorized as ACR Functional Class IV (largely or wholly incapacitated), or unable to walk without assistive devices
•Patients with other known rheumatic or inflammatory disease such as rheumatoid arthritis
•Other pathologic lesions on x-rays of knee
•Positive hepatitis B surface antigen, hepatitis C antibody test, Anti human immunodeficiency virus (HIV) antibody test, or VDRL

Outcomes

Primary Outcomes

Number and percentage of patients with adverse events as a measure of safety and tolerability

Time Frame: 1 year

* Safety evaluation will include assessment of physical examination, periodic monitoring of vital signs (heart rate, respiratory rate, blood pressure and temperature), clinical laboratory investigations (including haematology, serum chemistry, LFT, urine-analysis) and 12-lead ECG recording. * Tolerability: Adverse events monitored using information volunteered by the patients and as observed by the PI will be summarized descriptively by total number of AE(s) and compared between the study arms.

Secondary Outcomes

Change from baseline in radiographic (X-ray) findings of knee(1 Year)
Change from baseline in the WORMS score of knee using MRI(1 Year)
Change from baseline in arthritis pain scores on the visual analogue scale(1 Year)
Change from baseline in the WOMAC OA (Western Ontario and McMaster Universities Osteoarthritis) Index -pain subscale score(1 Year)
Change from baseline in WOMAC OA composite index(1 Year)
Change from baseline in WOMAC OA stiffness index(1 Year)
Change from baseline in ICOAP (Intermittent and Constant Osteoarthritis Pain)(1 Year)
Reduction in the intake of analgesic tablets from baseline(1 Year)
