Allocetra for Primary Knee Osteoarthritis

This study is testing a cell-based therapy called Allocetra for people with moderate-to-severe primary knee osteoarthritis (OA). Allocetra uses specially prepared immune cells to help reduce inflammation in the knee. You might be able to join if you are 64 or older, have a diagnosis of primary knee OA with specific X-ray findings (Kellgren-Lawrence grade 2 or 3), and haven't responded well to at least two other OA treatments. The study will compare Allocetra to a placebo (a look-alike substance with no active drug) to see if Allocetra can improve pain and function in your knee. We will measure your pain and function using a score called WOMAC at 3 months, and also track your safety for up to 6 months. The current status of this study is unclear.

Study design
This is a randomized, double-blind, placebo-controlled Phase IIb study involving 270 participants. You would be randomly assigned to receive either Allocetra or a placebo.
What's involved
You would receive three injections into your knee (on Day 0, Day 14, and Day 28).
Compensation
Not stated in the trial record.
Follow-up
You would be followed for 12 months after your treatment.
