Inclusion criteria

1. Voluntarily sign the informed consent form before starting the activities related to the trial; 2. The Numerical Evaluation Scale (NRS) pain score of the index knee joint at screening is ≥ 4; 3. Subjects must be willing to discontinue all medical and non-medical treatments for osteoarthritis pain except rescue medication (acetaminophen) and not use prohibited analgesics throughout the study ; 4. Male and female subjects of childbearing potential must agree to use highly effective contraceptive measures with their partners from the signing of the informed consent form until 1 month after the last dose of investigational product.

Exclusion criteria

Plan to undergo surgical procedure during the study; 4. Most or complete loss of mobility; 5. There are other diseases that may confuse the assessment of osteoarthritis pain; 6. There is a neuropsychiatric disease, and the investigator's assessment may affect the evaluation of osteoarthritis (OA) or self-score; 7. There are serious or poorly controlled concomitant diseases; 8. Those who have a clear history of peptic ulcer, bleeding, perforation or obstruction within 1 year before screening, and have been clinically diagnosed; 9.

Have a history of drug abuse, drug abuse and/or alcoholism within 2 years before screening.

Design outcomes

Primary

MeasureTime frame
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale scores.At week 4.

Secondary

MeasureTime frameDescription
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale scores.From baseline to Week 1, 2 and 3.
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) joint function subscale scores.From baseline to Week 1, 2, 3 and 4.
Change from baseline in the weekly mean (Week 1, 2, 3 and 4) of the index Knee Numerical Rating Scale (NRS) pain score (resting).From baseline to Week 1, 2, 3 and 4.
Change from baseline in the weekly mean (Week 1, 2, 3 and 4) of the index Knee Numerical Rating Scale (NRS) pain score (flat walking).From baseline to Week 1, 2, 3 and 4.
Change from baseline in the overall patient global assessment (PGA) of osteoarthritis condition using the 5-point Likert scale.From baseline to Week 1, 2, 3 and 4.
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) stiffness subscale scores.From baseline to Week 1, 2, 3 and 4.
Change from baseline in total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score.From baseline to Week 1, 2, 3 and 4.
Treatment response: WOMAC pain subscale scores decreased by ≥ 30%, ≥ 50%, ≥ 70% from baseline.At Week 1, 2, 3 and 4.
Adverse events (AEs) occurred during the study.During the study, approximately 8 months.To evaluate the safety and tolerability of HRS-2129 tablets.
Serious adverse events (SAEs) occurred during the study.During the study, approximately 8 months.To evaluate the safety and tolerability of HRS-2129 tablets.
