Study Details

Study Description

Brief Summary

Autologous stem cell therapy has been shown to be effective in patients with systemic sclerosis. Nevertheless treatment is associated with treatment related mortality and patients die during follow up despite successful transplantation.

Intention of this trial is to improve overall survival by modifying the existing protocol used for the ASTIS trial.

To reduce treatment toxicity we reduce the dose of Cyclophosphamide (CYC) for mobilisation to 2x1g.

Especially in patients with cardiac manifestations we also modify the conditioning regimen by adding thiotepa and reducing CYC; as CYC has known cardiotoxic side effects.

Condition or Disease Intervention/Treatment Phase
  • Drug: Autologous stemcell transplantation with CD (cluster of differentiation) 34 selected stem cells

Arms and Interventions

Arm Intervention/Treatment
Experimental: Conditioning with CYC/ antithymocyte globulin (ATG)

Each patient receives stem cell transplantation open label with cluster of differentiation (CD)34 selected stem cells mobilisation and conditioning depending on manifestation If cardiac manifestation: Conditioning with CYC 2 x 50mg + thiotepa 2x5mg + ATG If no cardiac manifestation: Conditioning with 4 x 50mg CYC + ATG

Drug: Autologous stemcell transplantation with CD (cluster of differentiation) 34 selected stem cells
If no active alveolitis: mobilisation with 2x1g Cyclophosphamide If active alveolitis: mobilisation with 2x1.5g Cyclophosphamid If cardiac manifestation: Conditioning with CYC 2 x 50mg + thiotepa 2x5mg + ATG If no cardiac manifestation: Conditioning with 4 x 50mg CYC + ATG

Experimental: Conditioning with CYC/Thiotepa/ATG

In patients with cardiac manifestations as defined in the protocol the conditioning for stem cell transplantation is changed to Cyclophosphamide (CYC), thiotepa and ATG

Drug: Autologous stemcell transplantation with CD (cluster of differentiation) 34 selected stem cells
If no active alveolitis: mobilisation with 2x1g Cyclophosphamide If active alveolitis: mobilisation with 2x1.5g Cyclophosphamid If cardiac manifestation: Conditioning with CYC 2 x 50mg + thiotepa 2x5mg + ATG If no cardiac manifestation: Conditioning with 4 x 50mg CYC + ATG

Outcome Measures

Primary Outcome Measures

  1. Efficay - Overall survival [3 years]

    Number of patients that are alive after 3 years

Secondary Outcome Measures

  1. Safety - Treatment related mortality [100 days]

    Treatment related mortality: number of patients who die during the first 100 days after transplantation

  2. Time to engraftment [2 months]

    Time in days from day 0 to platelet count > 20.000 and granulocytes >500/µl

  3. Progression free survival [3 years]

    Time after transplantation without symptoms of disease activity

  4. Efficacy - Lung function test and Skin [3 years]

    Number of patients that achieve either improvement of >25% in mRSS or > 10% in FVC or DLCO

Other Outcome Measures

  1. Efficacy - Patient reported outcome [3 years]

    Differences in Health Assessment Questionnaire (HAQ)
