Multiple Sclerosis Clinical Trial
A Safety and Efficacy Study of FCR001 in Adults With Rapidly Progressive Diffuse Cutaneous Systemic Sclerosis
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.
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.
Key Inclusion Criteria (Recipients):
Age ≥ 18 and < 70 years
Diagnosis of diffuse cutaneous systemic sclerosis
Disease duration < 5 years from first non-Raynaud's phenomenon symptom
Received at least one immunosuppressant in the past to treat the systemic sclerosis (SSc) or currently on an immunosuppressive therapy
Modified Rodnan Skin Score > 15 and < 40
Documented evidence of pulmonary or renal involvement by having at least one of the following:
a) Pulmonary, both required: i. FVC > 45% and < 80% predicted or hemoglobin-adjusted DLco > 45% and < 80% predicted AND ii. Interstitial lung disease evidenced by chest high-resolution computed tomography b) Renal: history of renal crisis that is not active at time of screening. Stable serum creatinine (< 20% increase) must be documented for a minimum of 3 months post-renal crisis at the time of the screening visit.
Key Inclusion Criteria (Donors): Age ≥ 18 and < 60 years
Key Exclusion Criteria (Donor and Recipient):
Use of investigational drugs within 30 days (or within 5 drug half-lives) of signing informed consent

History of malignancy (other than localized squamous or basal cell carcinoma of the skin or in-situ cervical cancer without recurrence) or premalignant syndrome within the past 5 years
Known bone marrow aplasia
Key Exclusion Criteria (Recipient):
Rheumatic disease, other than systemic sclerosis
FVC < 45% of predicted or hemoglobin-adjusted DLco < 45% of predicted

Estimated GFR < 40 mL/min
Previous treatment with cyclophosphamide, as defined by combination of prior oral and intravenous cyclophosphamide > 9 months, independent of dose
Corticosteroid therapy at prednisone equivalent doses of greater than 10 mg/day, or more than two pulses for concurrent illnesses within prior 12 months
Active gastric antral vascular ectasia, also known as "watermelon stomach"
Use of scleroderma specific therapies beyond protocol specified washout period, except for PDE-5 inhibitors for Raynaud's phenomenon and digital ulcers
Previous history of bone marrow transplant, total lymphoid irradiation, solid organ transplant, autologous or allogeneic hematopoietic progenitor or mesenchymal stem cell transplant
Presence of donor-specific antibodies
Body mass index < 18 or > 35 kg/m^2
Key Exclusion Criteria (Donor): Biologically unrelated female donor to male recipient
