Can I Participate?
You may be eligible to participate in this study if you:



‘Refractory’ means your scleroderma does not respond to standard therapies or medications.
Other eligibility criteria apply and will be evaluated by a study doctor if you choose to continue with screening for the study.
What is AlloNK® (AB-101)?
AlloNK®(AB-101) is an investigational treatment being studied to see if it can reduceB-cells that cause scleroderma. AlloNK® works by boosting your immune system using NK cells* from healthy donors, along with other treatments. NK cells help protect your body from harmful invaders.
When paired with another type of treatment called mAb therapy (example: rituximab), they may target the faulty B-cells that cause the symptoms of scleroderma. AlloNK® can be given outside of hospitals, in places like clinics or doctor’s offices, making it easier for you to potentially participate.
- *Natural killer (NK) cells: A type of immune cell that helps protect the body from infections and cancer. NK cells attack infected or abnormal cells but also avoid harming normal cells. NK cells are special because they can be used to treat many patients without needing gene editing or other genetic changes.
