Anti T-lymphocyte Immunoglobulin With Post Transplant Cyclophosphamide to Prevent GVHD Post Allogeneic Transplantation
Graft Versus Host Disease
About this trial
This is an interventional treatment trial for Graft Versus Host Disease focused on measuring anti thymocyte globulin, cyclophospamide, graft-versus-host disease, stem cell transplantation
Eligibility Criteria
Inclusion Criteria:
- Patients with MDS/AML
- 18 years or older and willing and able to comply with the protocol requirements.
- LVEF ≥ 40%. 2-D transthoracic echocardiogram (ECHO) is the preferred method of evaluation. Multigated Acquisition Scan (MUGA) is acceptable if ECHO is not available.
- Patients undergoing 8-10/10 HLA matched unrelated and unmanipulated PBSC transplantation
- Patients conditioned with reduced intensity or reduced toxicity conditioning of fludarabine with reduced dose (2 days) or myeloabalative doses (4 days) of busulfan or with treosulfan.
- Patients must sign written informed consent.
- Adequate birth control in fertile patients.
Exclusion Criteria:
- Patients undergoing other type of transplantation or with other type of basic disease other than AML or MDS.
- Patients with respiratory failure (DLCO < 30%).
- Active congestive heart failure (New York Heart Association [NYHA] Class III to IV), symptomatic ischemia, or conduction abnormalities uncontrolled by conventional intervention.
- Psychiatric conditions/disease that impair the ability to give informed consent or to adequately co-operate
- Bilirubin > 3.0 mg/dl, transaminases > 3 times upper normal limit
- Creatinine > 2.0 mg/dl
- ECOG-Performance status > 2
- Uncontrolled infection
- Pregnancy or lactation
- CNS disease involvement
- Pleural effusion or ascites > 1 liter.

Arms of the Study
Arm 1
Experimental
cyclophosphamide and ATLG
The study will include 2 phases. In the first phase escalated doses of post-transplant cyclophosphamide up to a maximal dose of 50 mg/kg administered on day +3 and +4 (target dose) will be added to a standard GVHD prophylaxis consisting of anti-human T-lymphocyte immunoglobulin (ATLG, Grafalon®, formerly ATG-Fresenius S, Neovii Pharmaceuticals) 15mg/kg total (5mg/kg day) on days -3 to -1 pre transplantation in order to find the maximally tolerated dose (MTD) of post-transplant cyclophosphamide (PTCy) in combination with pre-transplant immunosuppression by ATLG. The second phase will use the MTD cyclophosphamide dose identified in the first phase.
