NISSc-2 is a prospective observational study specifically designed to assess the effectiveness of various post-transplant treatment management approaches on clinical and immune biological responses after Autologous Hematopoietic Stem Cell transplantation (AHSCT) for Systemic Sclerosis (SSc) as currently performed by the different treatment protocols used in routine clinical practice across Europe in various EBMT centres through the careful recording and analysis of routinely collected clinical and immune biological data, and specific data regarding post-transplant use of SSc active treatments, including:
- SSc active treatments after AHSCT such as mycophenolate mofetil (MMF), azathioprine, cyclophosphamide (oral or IV), methotrexate, polyclonal antibodies (such as ATG) or monoclonal antibodies (rituximab, belimumab or any others) as well as their respective dosage and duration of each treatment. These post-transplant treatments can be administered for various reasons, which can be specified by local investigators, such as per local protocol decision for maintenance therapy, or for disease progression with or without prior clinical response, during routine clinical follow-up. Patients who do not receive any post-transplant therapy will also be observed.
Different protocols are used in the different centres, but it is not yet clear, which approach will be the most efficient and the safest. The role of stem cell purification with CD34-selection also needs to be determined prospectively.
In addition, the EBMT Autoimmune Diseases and Immunobiology Working Parties developed and implemented guidelines for 'good laboratory practice' in relation to procurement, processing, storage and analysis of biological specimens for immune reconstitution studies in AD patients before, during and after AHSCT . To follow post-transplant immune reconstitution according to ADWP GCP, results of routine analyses performed by centres under standardized conditions on available biological samples will be investigated in correlation to clinical outcome parameters. Every centre will follow its own local protocol for AHSCT, which usually refers to the recent update of the EBMT guidelines for AHSCT in autoimmune disease.
We therefore specifically designed NISCC-II to prospectively capture various post-ASHCT management protocols and their effect on the observed clinical response after AHSCT.

SSC patients treated with AHSCT
Procedure: Autologous HSCT
- Progression free survival (PFS), [ Time Frame: 2 years post transplant ]defined as survival since AHSCT without evidence of progression of SSc.
- Treatment related toxicity [ Time Frame: 100 days post-transplant ]Treatment related toxicity throughout the study period using WHO toxicity parameters (expressed as maximum grade toxicity per organ system, see appendix) Incidence of Adverse Events (AE) and Serious Adverse Events (SE) Neutrophil and platelet engraftment, defined as first day after transplantation with absolute neutrophil count > 0.5 x 109/L and platelet count >20 x 109/L (without platelet transfusion).
- 100 days Treatment Related Mortality (100d TRM) [ Time Frame: 100 days post-transplant ]defined as any death during 100 days following transplant that cannot be attributed to progression or relapse of the disease
- Overall Survival (OS) [ Time Frame: 2 years post-transplant ]Overall survival
- Use of prednisone equivalent [ Time Frame: 1 year and 2 years post-transplant ]Use of prednisolone equivalent > 6 mg/day for more than 3 months
- Use of immunosuppressive drugs [ Time Frame: 2 years post-transplant ]defined as use of any post-transplant immunosuppressive drugs (mycophenolate mofetil, azathioprine, oral or iv cyclosphosphamide or methotrexate) for either causes (maintenance therapy as per local protocol decision, SSc progression or relapse) and total duration of exposure to this post-transplant immunosuppressive treatment (average monthly daily dose and months duration)
- Use of post-transplant biotherapies [ Time Frame: 2 years post-transplant ]defined as use of any monoclonal (i.e. anti CD20, anti-BLyS, alemtuzumab or polyclonal (i.e. ATG) antibodies for either causes (per local protocol decision, EBV infection or reactivation, progression or relapse) and total doses (in number and g/kg)
- Response to treatment [ Time Frame: 1 year and 2 years post-transplant ]
defined as any of the following changes
- 25% improvement in mRSS and/or
- ≥10% improvement in DLCO or FVC as compared to baseline (before mobilisation)
- Infectious complications, CMV / EBV reactivation [ Time Frame: 2 years post-transplant ]Infectious complications, CMV / EBV reactivation
- Secondary autoimmune diseases and secondary malignancy [ Time Frame: 2 years post-transplant ]defined, autoimmune thrombocytopaenia, autoimmune thyroid disease, autoimmune haemolytic anaemia, Evans' syndrome, acquired haemophila, ulcerative colitis, rheumatoid arthritis and spondyloarthropathy, autoimmune hepatitis, others) and secondary malignancy (EBV lymphoproliferative disorders, AML, MDS, skin cancers, and any others
- Immune reconstitution [ Time Frame: 2 years post-transplant ]Results of routine analysis performed by centres will be investigated in correlation to clinical outcomes parameters and will allow to follow post-transplant immune reconstitution according to ADWP GCP.
