Eligibility Criteria
Key Inclusion Criteria
- Male and female participants >= 50 and =1.8 mg/L at screening
- Symptomatic OA with pain (corresponding to Numeric Rating Scale [NRS] 5-9, inclusive) in the target knee for the majority of days in the last 3 months prior to screening
- KOOS pain sub-scale score 4 out of 19), or a known systemic connective tissue disease
- Any known active infections, including skin or knee infections or infections that may compromise the immune system, such as HIV or chronic hepatitis B or C infection. COVID-19 specific: PCR or antigen test against COVID-19 is mandatory where required by the local Health Authority and/or by local regulation, e.g. in Germany.
- Use of prohibited medications: any local i.a. treatment into the knee, including but not restricted to viscosupplementation and corticosteroids within 12 weeks prior to Day 1; long-term treatment (>14 days) with oral corticosteroids >5 mg/day within 4 weeks prior to Day 1; oral glucosamine, chondroitin sulfate, or any nutraceutical with potential activity on cartilage repairfrom screening 1; systemic Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), selective Cyclooxygenase-2 (COX- 2) inhibitors or other non-opioid analgesics not defined as basic pain medication within 5 half-lives from PRO assessments; any other immunomodulatory drugs or treatment which cannot be discontinued or switched to a different medication within 28 days or 5 half-lives of screening (whichever is longer if required by local regulations), or until the expected PD effect has returned to baseline.
- Moderate to severe pain in the contralateral knee for the majority of days in the last 3 months prior to Screening, as per patient judgment.
- Severe malalignment greater than 7.5 degrees in the target knee (either varus or valgus), measured using x-ray at Screening.
Additional protocol-defined inclusion / exclusion criteria may apply.
