Phase II Study of Cladribine Plus Low Dose Cytarabine (LDAC) Induction Followed By Consolidation With Cladribine Plus LDAC Alternating With Decitabine in Patients With Untreated Acute Myeloid Leukemia (AML) or High-Risk Myelodysplastic Syndrome (MDS)
The goal of this clinical research study is to learn if cladribine given in combination with low-dose cytarabine (LDAC) and decitabine can help control the disease in patients with AML or MDS. The safety of this drug combination will also be studied. Cladribine is designed to interfere with the cell's ability to process DNA (the genetic material of cells). It can also insert itself into the DNA of cancer cells to stop them from growing and repairing themselves. Cytarabine is designed to insert itself into DNA of cancer cells to stop them from growing and repairing themselves. Decitabine is designed to damage the DNA of cells, which may cause cancer cells to die. This is an investigational study. Cladribine is FDA approved and commercially available for use in patients with hairy cell leukemia. Its use in patients with AML is investigational. Cytarabine is FDA approved and commercially available for use in patients with AML. Decitabine is FDA approved and commercially available for use in patients with MDS. Its use for patients with AML is investigational. Up to 160 patients will take part in this study. All will be enrolled at MD Anderson.
⁃ Patients with previously untreated AML or high risk MDS (\>/= 10 % blasts or IPSS \>/= intermediate-2). Prior therapy with hydroxyurea, hematopoietic growth factors, azacytidine, ATRA, or total dose of cytarabine up to 2g is allowed. Patients with history of MDS transformed to AML are eligible regardless of their prior therapy for MDS provided this will be their first induction therapy for AML.
⁃ Age \>/= 60 years. Patients aged \< 60 years who are unsuitable for standard induction therapy may be eligible after discussion with PI
⁃ Adequate organ function as defined below:
∙ liver function (bilirubin \< 2mg/dL, AST and/or ALT \<3 x ULN)
‣ kidney function (creatinine \< 1.5 x ULN ).
⁃ ECOG performance status of ≤ 2.
⁃ A negative urine pregnancy test is required within 1 week for all women of childbearing potential prior to enrolling on this trial.
⁃ Patient must have the ability to understand the requirements of the study and signed informed consent. A signed informed consent by the patient is required prior to their enrollment on the protocol.
⁃ Prior therapy with decitabine will be allowed unless the patient experienced progression to AML while being treated with decitabine.
• 8\. Patients with previously untreated AML who are not currently eligible for other frontline clinical trials of AML therapy. Prior therapy with hydroxyurea, hematopoietic growth factors, azacytidine, ATRA, or total dose of cytarabine up to 2g is allowed. Patients with history of MDS transformed to AML are eligible regardless of their prior therapy for MDS provided this will be their first induction therapy for AML.
• 9\. Age \>/= 18 years who are unsuitable for standard induction therapy are eligible after discussion with PI 10. Patients must have one of the following:
• Creatinine \>/= 2 mg/dL
• Total bilirubin \>/= 2 mg/dL
• ECOG Performance Status equal to 3 or 4
• Is ineligible for participation in a protocol of higher priority 11. A negative urine pregnancy test is required within 1 week for all women of childbearing potential prior to enrolling on this trial.
• 12\. Patient must have the ability to understand the requirements of the study and signed informed consent. A signed informed consent by the patient is required prior to their enrollment on the protocol.
• 13\. Prior therapy with decitabine will be allowed unless the patient experienced progression to AML while being treated with decitabine.
⁃ Patients with relapsed and or refractory AML who have received at least one prior therapy for their AML.
⁃ Age \>/= 18 years.
⁃ Adequate organ function as defined below:
∙ liver function (bilirubin \< 2mg/dL, AST and/or ALT \<3 x ULN)
‣ kidney function (creatinine \< 1.5 x ULN ).
⁃ ECOG performance status of ≤ 2.
⁃ A negative urine pregnancy test is required within 1 week for all women of childbearing potential prior to enrolling on this trial.
⁃ Patient must have the ability to understand the requirements of the study and signed informed consent. A signed informed consent by the patient is required prior to their enrollment on the protocol.
⁃ Prior therapy with venetoclax will be allowed.
