Detailed Description

The study consists of a Screening Period (including a Diary Run- In/analgesic wash-out Period), Randomization, Post-Randomization Period, and a Follow-up Period. Up to 624 participants will be enrolled and randomized to one of four Treatment Arms at the ratio 1:1:1:1

   1. Completion of Average Daily (NRS) Pain score on at least 6 of the 7 days.
   2. Mean Average Daily (NRS) Pain score must be ≥4.0 and ≤9.0
   3. Mean Average Daily (NRS) Pain variability must be ≤1.5
10. If female, not of childbearing potential defined as post-menopausal for at least 1 year, or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or practicing an agreed upon highly effective method of birth control throughout the study period.
11. If male and sexually active with partner of childbearing potential, willing to agree to practice a highly effective method of contraception from Visit 2 and at least 3 months after Visit 11 (week 20).

13. Participant agrees to take only the allowed Rescue Medications from the start of the Diary Run-In Period through study completion (maximum 4000 mg paracetamol per day).

Exclusion Criteria:

1. Presence of OA of other major joints (including but not limited to nontarget knee) that could interfere with assessment of pain due to OA of the target knee, in the opinion of the investigator.
2. Current comorbid condition, other than OA, known to be significantly associated with arthritis or joint pathology, including but not necessarily limited to autoimmune disease with significant joint involvement (e.g., Rheumatoid Arthritis or Paget's disease; Seronegative Spondyloarthropathies (e.g. Ankylosing Spondylitis, Psoriasis arthritis, Reactive arthritis); or other systemic disease involving the target knee (including endocrinopathies).
3. The following conditions should be excluded: Known presence of rapidly Progressive Osteoarthritis (RPOA), primary osteonecrosis (including spontaneous osteonecrosis of the knee), subchondral insufficiency fractures (SIF), avascular necrosis, osteoporotic fractures, atrophic OA, excessive malalignment of the knee (anatomical axis angle greater than 10 degrees), pathological fractures, or stress fracture or reaction, vertical tear of the posterior meniscal root, or large or extensive subchondral cysts, or target knee anserine or patellar bursitis of clinical relevance
4. Hip dislocation and congenital hip dysplasia with degenerative joint disease should be excluded.
5. History of gout with recent (< 6 months) pain flares and uncontrolled uric acid levels. Participants with a history or diagnosis of pseudogout (calcium pyrophosphate dihydrate crystal deposition disease) can enroll if there has not been a flare within 6 months prior to screening and use of NSAIDs is not required for management of this condition.
