Could a One-Time cell infusion tame lupus and other autoimmune diseases?
NCT ID NCT06308978
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study is testing a new cell therapy called FT819 for people with severe autoimmune diseases like lupus, vasculitis, and scleroderma. The treatment involves giving specially engineered immune cells along with chemotherapy drugs. The main goal is to see if it's safe and to find the right dose, with a secondary look at whether it can control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FT819 (a type of immune cell therapy made from stem cells, given by IV)
- What this could lead to
- If it works, this could point toward a new treatment option for people with severe autoimmune diseases like lupus that haven't responded to other therapies.
- What could go wrong
- This is a very early (Phase 1) trial, so the main goal is safety, not effectiveness. It's small and may not lead to a proven treatment. There are also risks from the chemotherapy drugs given alongside FT819.
