The purpose of this study is to compare Reduced Intensity Conditioning protocols containing either Thymoglobuline or Alemtuzumab in patients undergoing allogeneic transplant from voluntary unrelated donors.

Clinical Details

Official title: Randomized Study for Comparison of Reduced Intensity Conditioning Protocols Containing Either Thymoglobuline or Alemtuzumab in Patients Undergoing Allogeneic Transplant From Voluntary Unrelated Donors

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Overall Survival

Event Free Survival and Disease Free Survival


Major infective complications (CMV and EBV related PTLD)

Acute and chronic GvHD

Secondary outcome:

Haematological and immunologic reconstitution

Incidence of CMV and EBV reactivation

Other infective complications

Other toxicities

Need for DLI

Detailed description: The reduction of intensity of conditioning is currently indicated for patients who cannot undergo standard myelo-ablation due to their age, comorbidities or type of pathology. Furthermore, the rationale to use RIC regimens is based on the observation that the infusion of alloreactive donor lymphocytes may yield to a graft versus tumour effect. However, in this kind of regimens the morbidity and TRM due to GvHD are still a concern and in vivo T-depletion is a necessary treatment. Both monoclonal (Alemtuzumab) and polyclonal T-depletion protocols carry risks and benefits. Benefits being a better prophylaxis for GvHD, and risks being an higher incidence of post-transplantation infections and relapse. At the moment, it is not clear which type of regimen, monoclonal or polyclonal, is better for the treatment.


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.
