Brief Summary:
This is a multicenter, open-label study to evaluate the safety and tolerability and explore the efficacy of FCR001 cell therapy in adults with rapidly progressive Diffuse Cutaneous Systemic Sclerosis (dcSSc) at risk for organ failure.

Condition or disease Intervention/treatment Phase
Diffuse Cutaneous Systemic Sclerosis Biological: FCR001 Phase 1 Phase 2

Detailed Description:

The purpose of this multicenter, single-arm study is to evaluate the safety and tolerability and explore the efficacy of FCR001 cell therapy in adults with rapidly progressive dcSSc at risk for organ failure. It consists of 2 years of treatment and 3 years of follow-up, with the primary analysis performed at 24 months.

FCR001 is a cell therapy product that is administered by intravenous (IV) infusion, following nonmyeloablative (NMA) conditioning. It consists of mobilized peripheral blood cells, facilitating cells, and αβ T cells. This therapy is designed to induce donor-specific tolerance by establishing sustained chimerism and to protect against graft versus host disease (GvHD), the major impediment for advancing allogeneic hematopoietic stem cell therapy (HSCT) as a potential therapy in patients.
