Scleroderma: Cyclophosphamide or Transplantation
SCOT
A Randomized, Open-Label, Phase II Multicenter Study of High-Dose Immunosuppressive Therapy Using Total Body Irradiation, Cyclophosphamide, ATGAM, and Autologous Transplantation With Auto-CD34+HPC Versus Intravenous Pulse Cyclophosphamide for the Treatment of Severe Systemic Sclerosis (SCSSc-01)

Brief Summary
SCOT is a clinical research study designed for people with severe forms of scleroderma. SCOT stands for Scleroderma: Cyclophosphamide Or Transplantation. The SCOT study will compare the potential benefits of stem cell transplant and high-dose monthly cyclophosphamide (Cytoxan) in the treatment of scleroderma.

Outcome Measures
Primary Outcomes (1)
Global Rank Composite Score (GRCS) (Month 54, ITT)
The GRCS is an analytic tool that accounts for multiple disease manifestations simultaneously. It does not measure clinical disease activity or severity but reflects how participants compared to one another based on a hierarchy of ordered outcomes: death, event-free survival (EFS), forced vital capacity (FVC), Health Assessment Questionnaire - Disability Index (HAQ-DI), and Modified Rodnan Skin Score (mRSS). Participants alive ranked higher than those who died; those who survived event-free ranked higher than EFS failures. EFS failure included death, respiratory failure (decrease from baseline of \>30% in DLCO % predicted or \>20% in FVC % predicted ), renal failure (chronic dialysis \> 6 month or renal transplant), or cardiac failure (clinical congestive heart failure or left ventricular ejection fraction \<30%). The lowest 3 GRCS components are ordinal; improvement, stability, or worsening from baseline (±10% change in FVC % predicted, ±0.4 change in HAQ-DI, ±25% change in mRSS).

Study Arms (2)
mHSCT
EXPERIMENTALMyeloablative Hematopoietic Stem Cell Transplant (mHSCT) Participants will first have hematopoietic stem cells removed from their blood. They then will receive high doses of chemotherapy and radiation to eliminate their developed and presumably abnormal immune system, followed by autologous stem cell transplantation to reintroduce the purified stem cells to re-establish their immune system.
cyclophosphamide
EXPERIMENTALCyclophosphamide (CY) Participants will receive high doses of intravenous cyclophosphamide. The dose being used in this study is about 50% higher than that commonly used by most physicians to treat many other autoimmune diseases. Administration of 12 monthly pulses of high-dose intravenous cyclophosphamide (an initial dose of 500 mg/m\^2, followed by 11 doses of 750 mg/m\^2).
Interventions
Hematopoietic progenitors were mobilized with G-CSF. After leukapheresis and CD34+ cell enrichment, the autologous product was cryopreserved. Fractionated TBI (800 cGy), CY (120 mg/kg) and equine antithymocyte globulin (90 mg/kg) were administered as previously reported (References provided in citation section of this ClinicalTrials.gov record: PubMed ID: 17452515 citation and 2.) PubMed ID: 12176878 citation).
An initial intravenous dose of 500 mg/m\^2 was followed by 11 infusions of 750 mg/m\^2 with mesna given for bladder protection.
Eligibility Criteria
You may qualify if:
- Severe systemic sclerosis (SSc) as defined by the American College of Rheumatology (ACR);
- SSc, including extensive skin and internal organ involvement involving either the lungs or the kidneys, that threatens participant's life; and
- Willingness to use accepted methods of contraception for at least 15 months after starting study treatment.
You may not qualify if:
- Lung, heart, liver, or kidney impairment that would interfere with the study or compromise participant's survival;
- Active blood vessel dilation in the stomach (Active Gastric Antral Vascular Ectasia/GAVE, also known as "watermelon stomach"). Patients found to have this disorder at study screening can receive treatment outside the study and then be re-screened. For more information about this study criterion, refer to the study protocol.
- Previous treatment with cyclophosphamide, as defined by: a) prior IV cyclophosphamide administration for more than 6 months OR a total cumulative IV dose greater than 3 g/m\^2; b) prior oral cyclophosphamide administration for more than 4 months, regardless of dose; or c) combination of prior oral and IV cyclophosphamide administration for more than 6 months, independent of dose.
- Steroid therapy at doses of greater than 10 mg/day, or more than 2 pulses for concurrent illnesses within prior 12 months;
- Unwillingness or inability to discontinue certain disease-modifying antirheumatic drugs (DMARDs) for the treatment of SSc;
- Presence of clinically significant rheumatic diseases other than scleroderma requiring significant immunosuppression;
- Any active uncontrolled infection that would interfere with high-dose therapy or pulse cyclophosphamide regimens:
- Hepatitis B virus infected
- Hepatitis C virus infected or
- HIV infected.
- Blood abnormalities;
- Diagnosis of cancer within 2 years prior to study entry. Participants with adequately treated squamous cell skin cancer, basal cell carcinoma, and carcinoma in situ are not excluded.
- Other comorbid illnesses with an estimated life expectancy of less than 5 years;
- Defective formation of bone marrow cells (myelodysplasia);
- Uncontrolled hypertension;
- +3 more criteria

- IPD Sharing
- Will share
The plan is to share IPD in the Immunology Database and Analysis Portal (ImmPort), a long-term archive of clinical and mechanistic data from DAIT-funded grants and contracts. This archive is in support of the NIH mission to share data with the public. Data shared through ImmPort has been provided by NIH-funded programs, other research organizations and individual scientists ensuring these discoveries will be the foundation of future research.
