Study Summary
This trial is testing whether a medication injected into the knee joint can improve symptoms more than just injecting salt water.
Who is the study for?
Adults aged 35-85 with chronic knee pain and swelling from osteoarthritis (KL grade 3 or 4), who haven't found relief with other treatments like hyaluronic acid or corticosteroids. Participants should have a BMI ≤40, no severe joint diseases besides OA, not be using opioids, and women of childbearing age must use birth control.Check my eligibility
What is being tested?
The trial is testing if a single injection of TTAX03 (a treatment derived from human amniotic and umbilical cord tissues) can provide more relief for knee arthritis pain after 12 weeks compared to a saline placebo, based on established responder criteria.See study design
What are the potential side effects?
While the specific side effects are not listed here, similar injections may cause temporary pain at the injection site, swelling, infection risk increase, allergic reactions or no improvement in knee pain.

Group I: Experimental: TTAX03Experimental Treatment1 Intervention
TTAX03 is a sterile, lyophilized and micronized particulate human AM and UC product manufactured using aseptic processing followed by terminal sterilization by gamma irradiation in compliance with current Good Tissue Practices (cGTP) and current Good Manufacturing Practices (cGMP) to preserve extracellular matrices and growth factors/cytokines therein without any living cells. TTAX03 is suspended in a volume of 2.0mL of sterile, preservative free 0.9% NaCl.
Group II: Control: SalinePlacebo Group1 Intervention
2.0mL of sterile, preservative free 0.9% NaCl alone
