Rheumatoid Arthritis (RA) Clinical Research Study
Recruiting
The Ntrust-2 study is a clinical research study evaluating an investigational cell therapy, called NKX019, in adults living with rheumatoid arthritis (RA).
The Ntrust-2 study
The Ntrust-2 study is part of a broad effort of the global research community to develop more treatment options for people living with rheumatoid arthritis.
What is NKX019?
NKX019 is an investigational cell therapy being studied for rheumatoid arthritis (RA). It is designed to target and remove the cells that may trigger harmful antibodies, which attack the body’s own tissues in these conditions.
Who can join this study?
You may be eligible to participate in this study if you:
- Are 18 to 75 years old
- Have been diagnosed with rheumatoid arthritis (RA)
- Have received prior autoimmune disease treatments that may have not worked well for you
Compensation
If you are eligible and choose to participate, you will receive NKX019 and health assessments from a team with expertise in caring for people living with autoimmune disease. Costs for travel, lodging, childcare, and meals will be covered when you and your care partner go to the study clinic. Compensation for study participants and your care partner may also be available.
