Clinical Trial Summary

The present project is a multicenter phase II trail aiming at comparing which of the two postgrafting immunosuppressive regimens proposed in this study will be best suited to prevent graft-versus-host disease (GVDH).

The immunosuppressive regimens will consist of: Tacrolimus plus Mycophenolate Mofetil or Tacrolimus plus Sirolimus. Before grafting patients will undergo a reduced-intensity conditioning with Fludarabine/total body irradiation (TBI) or Fludarabine/Busulfan/anti-thymoglobuline. Following the interim analysis of October 2014, the protocol has been amended to allow inclusion only after Flu-TBI conditioning. The hypothesis is that the Tacrolimus plus Sirolimus regimen will be associated with better progression-free survival due to a lower incidence of relapse/progression.

1. Cardiac: Symptomatic coronary artery disease or other cardiac failure requiring therapy; ejection fraction <35%; uncontrolled arrhythmia, uncontrolled hypertension;

2. Pulmonary: DLCO < 35% and/or receiving supplementary continuous oxygen;

3. Hepatic: Fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin >3 mg/dL, and symptomatic biliary disease;

• Uncontrolled infection;

• Karnofsky Performance Score <70%;

• Patient is a fertile man or woman who is unwilling to use contraceptive techniques during and for 12 months following treatment;

• Patient is a female who is pregnant or breastfeeding;

• Any condition precluding the use of sirolimus or MMF;

• One HLA mismatch with peripheral blood stem cells (PBSC) fit to/willing to donate.

Related Conditions & MeSH terms

• Graft vs Host Disease
• Graft-Versus-Host Disease
• Hematologic Neoplasms
• Hematological Malignancies

Intervention

Drug:
• Mycophenolate mofetil
Tablets. For HLA-identical sibling donors:15 mg/kg t.i.d from day 0 to day 28. For alternative donor: 15 mg/kg, from day 0 to day 42.
• Sirolimus
Tablets. 6 mg loading dose on day -3, followed by (1)-2 mg daily to a target trough level of 5 to 10 ng/mL. Full doses will be given until day 100 (sibling recipients) or 180 (alternative donor recipients). Doses will then be progressively tapered to be definitely discontinued by day 180 (sibling donors) or 365 (alternative donor recipients) in the absence of GVHD.
