ClinicalTrials.gov ID: NCT06733935

What this study is testing

What is NKX019?

NKX019 is an investigational drug being studied as a potential treatment for systemic sclerosis.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study aims to find out how safe and tolerable NKX019 is for people with these autoimmune conditions.
Who it's for
Adults who have systemic sclerosis, idiopathic inflammatory myopathies, antineutrophil cytoplasmic antibody‑associated vasculitis, or rheumatoid arthritis.
What's involved
Participants will receive NKX019 cells and attend scheduled clinic visits for monitoring and blood tests.
  • Phase 2: a mid-size study of how well it works
