Phase II Study of 5-azacytidine Maintenance After Transplant for AML or MDS

Withdrawn before enrolling · Phase 2

Conditions studied: Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS)

In brief

Despite improvements in outcomes after Hematopoietic Cell Transplantation (HCT) for Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS), the risk of relapse remains high and is the most common cause of mortality after HCT. Moreover, treatment options for relapse after HCT are limited. Strategies to reduce relapse with maintenance therapy in patients who are at high risk are needed to improve survival. 5-aza is a hypomethylating agent that has shown immune modulating properties that may enhance the graft-versus-leukemia (GVL) effect, including upregulation of tumor-associated antigen and costimulatory molecule expression. Moreover, 5-aza has properties that suggest protection against graft-versus-host disease (GVHD) as well. Preliminary data shows that it is well tolerated and effective in clinical use for the treatment of AML or MDS relapse after HCT, as well as for maintenance therapy. This study will evaluate the use of 5-aza for maintenance after HCT in patients with AML or MDS with risk factors that are associated with a high risk for relapse.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age≥18 with MDS or high-risk AML, morphologically confirmed and based on World Health Organization criteria (see below for definition of high-risk AML)*, who are transplant candidates with an available human leukocyte antigen (HLA) -matched sibling or unrelated donor with at least 8/8 match
• Definition of high-risk AML:
• Age≥60 years
• Age<60 years with any of the following:
• Secondary AML
• Poor risk cytogenetics, which include abnormalities of chromosome 3, 5, or 7, trisomy 8, 11q23 abnormalities, t(6;9), 20q-, and complex karyotype
• Fms-like tyrosine kinase 3 (FLT3) mutation
• Disease status ≥ second complete remission (CR2) at time of HCT
• Detectable disease at time of HCT
• Eastern Cooperative Oncology Group (ECOG) performance status 0-2
• Adequate major organ function, as defined by AST and ALT < 2 x upper limit of normal, total serum bilirubin < 2 x upper limit of normal (unless due to hemolysis or Gilbert's syndrome, then no upper limit), creatinine < 2 x upper limit of normal, unless there is known chronic kidney disease (creatinine must be at baseline for subjects with chronic kidney disease)
• In agreement to use an effective barrier method of birth control to avoid pregnancy during the study and for a minimum of 30 days after study treatment, for all male and female patients who are fertile

You may not qualify if…

• Uncontrolled, life-threatening infection that is not responding to antimicrobial therapy
• Serum creatinine > 2 x upper limit of normal, unless there is known chronic kidney disease (creatinine must be at baseline for subjects with chronic kidney disease), aspartate aminotransferase (AST),alanine aminotransferase (ALT), or total bilirubin > 2x upper limit of normal
• History of psychiatric disorder which may compromise compliance with the protocol or which does not allow for appropriate informed consent
• Patient may not be receiving any other antineoplastic agents
• Pregnancy
• Concurrent use of any other investigational agents on a clinical trial
• Prior allogeneic stem cell transplant
• Known hypersensitivity to 5-azacytidine * Prior treatment with 5-azacytidine is allowed
• Post-transplant eligibility and exclusion criteria
• Patients will have to meet the following post-transplant eligibility criteria to initiate treatment:
• In complete response (including complete remission with incomplete blood count recovery and marrow complete response) on bone marrow biopsy for response assessment after HCT (typically day +30)
• Patient is within 30-100 days after HCT
• Absolute neutrophil count (ANC) ≥ 1000/µL, platelet count ≥ 20,000/µL
• ECOG performance status 0-2
• Adequate major organ function, as defined by AST and ALT < 2 x upper limit of normal, total serum bilirubin < 2 x upper limit of normal (unless due to hemolysis or Gilbert's syndrome, then no upper limit), creatinine < 2 x upper limit of normal unless there is known chronic kidney disease (creatinine must be at baseline for subjects with chronic kidney disease)
• In agreement to use an effective barrier method of birth control to avoid pregnancy during the study and for a minimum of 30 days after study treatment, for all male and female patients who are fertile
• Patients may not have any of the following post-transplant exclusion criteria:
• Active grade II-IV acute GVHD, for example requiring treatment with steroids at a dose equivalent to prednisone 1mg/kg daily or higher
• Uncontrolled, life-threatening infection that is not responding to antimicrobial therapy
• Serum creatinine > 2 x upper limit of normal unless there is known chronic kidney disease (creatinine must be at baseline for subjects with chronic kidney disease), aspartate aminotransferase (AST),alanine aminotransferase (ALT), or total bilirubin > 2x upper limit of normal
• History of psychiatric disorder which may compromise compliance with the protocol or which does not allow for appropriate informed consent
• Pregnancy
• Concurrent use of any other investigational agents on a clinical trial
• Known hypersensitivity to 5-azacytidine * Prior treatment with 5-azacytidine is allowed
