E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To improve the response rate to treatment of acute GvHD grade II-IV (with gut and/or liver involvement) by early addition of MSC to standardized second line treatment. |
|
E.2.2 | Secondary objectives of the trial |
• To study the safety of MSC addition to second line treatment
• To assess the overall survival
• To assess the progression-free survival
• To reduce the time required for continued pharmacological immune suppression
• To assess the incidence of severe bacterial, viral and fungal infections
• To assess the incidence and severity of chronic GvHD
• To evaluate the quality of life of patients treated with MSC in comparison with controls up to two years after MSC treatment
• To develop a score by means of clinical and laboratory parameters that allows for identification of patients with acute GvHD that will respond to MSC treatment
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Grade II-IV acute GvHD with gut and/or liver involvement, confirmed by histology of involved tissues (in case of gut and liver involvement histology of either one of these tissues is considered sufficient);
• Non-responsive to treatment with steroids and a calcineurin-inhibitor defined as:
- progressive disease of mixed response after 5 days of consecutive systemic treatment with steroids at a dose of 2 mg/kg and a calcineurin-inhibitor at therapeutic trough levels.
- stage 4 GvHD of gut and/or liver and deterioration of clinical parameters (gut) or increase of serum total bilirubin levels in micromol/L (liver) after 5 days of consecutive systemic treatment with steroids at a dose of 2 mg/kg and a calcineurin-inhibitor at therapeutic trough levels
- stable disease after 10 days of consecutive systemic treatment with steroids at a dose of 2 mg/kg and a calcineurin-inhibitor at therapeutic trough levels.
- progressive disease after initial partial repsons of maximal 1 grade after 10 days of consecutive systemic treatment with steroids at a dose of 2 mg/kg and a calcineurin-inhibitor at therapeutic trough levels.
• Any age;
• Lansky / Karnofsky score of ≥20;
• Signed informed consent by the patient and/or parent(s) or legal guardian(s);
|
|
E.4 | Principal exclusion criteria |
• Use of prophylactic MMF, Myfortic or other systemic treatment for acute GvHD <= 6 days prior to development of acute GvHD grade II-IV with gut and/or liver involvement.
• Systemic treatment for acute GvHD other than steroids and a calcineurin inhibitor (budesonide is considered a local treatment).
• Previous treatment with MSC.
• Progressive or relapsing malignant disease in case of NHL, HL, CLL, MM, and ≥ 5% blasts in the bone marrow in case of AML, ALL, CML;.
• Requiring ventilator or vasopressor support.
• Poor performance not expected to survive 14 days.
• Known seropositivity of HIV, Hepatitis B and C, HTLV.
• Known uncontrolled toxicity for DMSO.
• Known anaphylactic reaction to penicillin or streptomycin;
• Known pregnancy;
• Any psychological, familial, sociological and/or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

|
E.5.2 | Secondary end point(s) |
- Overall Survival

|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
An interim analysis will take place when 50% of the patients are included. These results will be reviewed confidentially by the DSMB.
Final analysis will take place when the relevant data of all patients are available |
