Age 40-70, male or female; 3. Osteoarthritis that meets ACR criteria, symptoms lasting for at least 3 months (may be diagnosed at screening time); 4. Radiographic X-rays were graded 2-3 by Kellgren & Lawrence. KL grading criteria: Grade 1 slight osteophyte; Grade 2 osteophytes were evident, but no joint space was involved. Grade 3 moderate joint space stenosis; Grade 4 joint space narrowing, subchondral sclerosis); 5. Subjects' baseline pain score for the affected joint was moderate or severe pain (VAS >= 40mm); 6. At the time of screening, if subjects were taking non-steroidal anti-inflammatory drugs (NSAIDs), the dose was stable for at least 2 weeks prior to initial administration; 7. Women with less than 2 years of childbearing or menopause; 8. The investigator considers that the subject needs to be treated with NSAIDs, and it is expected that the subject will be treated with NSAIDs continuously for more than 8 weeks; 9. No new cardiovascular and cerebrovascular diseases occurred within 6 months, including unstable angina pectoris, acute myocardial infarction, acute cerebral ischemia, and cerebral infarction. Patients with stable hypertension under drug control could be included.

Abnormal laboratory results: Blood routine examination: WBC 1.5 times the upper limit of normal value; ALT or AST > 2.5 times the upper limit of normal value; Renal function: creatinine > 1.5 times the upper limit of normal, with creatinine clearance < 50 mL /min (measured or calculated by the Cockcroft-Gault formula); HIVAb positive, HBsAg positive, HBcAb positive, HCVAb positive, syphilis antibody positive (any positive results will be excluded); 10. Participants in clinical trials of other drugs within 3 months prior to screening; 11. Received articular or intramuscular or intravenous corticosteroid injections within 4 weeks prior to screening; 12. Women who are pregnant, breastfeeding, and preparing for pregnancy; 13.
