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. |
Mejorar la tasa de respuesta al tratamiento de la EICH aguda grados II-IV (con afectación de hígado y/o intestino) mediante la adición precoz de CSM al tratamiento estándar de segunda línea |
|
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 |
•Estudiar la seguridad de la adición de CSM a la segunda línea de tratamiento •Evaluar la supervivencia global. •Evaluar la Supervivencia Libre de Progresión. •Disminuir el tiempo en el que es necesaria una inmunosupresión farmacológica continua •Evaluar la incidencia de las infecciones bacterianas, víricas y fúngicas graves. •Evaluar la incidencia y gravedad de la EICH crónica •Evaluar la calidad de vida del paciente en tratamiento con CSM en comparación
con controles hasta los 2 años tras el tratamiento con CSM. •Desarrollar una puntuación (score) de parámetros clínicos y de laboratorio que permita la identificación de
pacientes con EICH aguda que responderán al tratamiento con CSM

E.4 | Principal exclusion criteria |
* In Spain only adult patients will be included * Use of prophylactic MMF or Myfortic ? 6 days prior to development of acute GvHD ; * Systemic treatment for acute GvHD other than steroids and a calcineurin inhibitor (budesonide is considered a local treatment); * Pre-treatment with steroids ? 1 mg/kg for more than 3 days prior to initiation of steroids at a dose of 2 mg/kg for the treatment of acute GvHD; * Previous treatment with advanced therapy medicinal products (ATMP) potentially interfering with the endpoints of this study; N.B. if the patient has previously been treated with ATMP , the principal investigator should always be contacted prior to registration*. * 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. |
