Decitabine and Cedazuridine in Combination With Venetoclax for the Treatment of Patients Who Have Relapsed Acute Myeloid Leukemia After Donor Stem Cell Transplant

Stopped early · Phase 2

Conditions studied: Recurrent Acute Myeloid Leukemia

In brief

This phase II trial tests how well decitabine and cedazuridine (DEC-C) works in combination with venetoclax in treating acute myeloid leukemia (AML) in patients whose AML has come back after a period of improvement (relapse) after a donor stem cell transplant. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving DEC-C in combination with venetoclax may kill more cancer cells in patients with relapsed AML.

Who can join

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

You may qualify if…

• Age >= 18 years at the time of signing the Informed Consent Form (ICF); must voluntarily sign an ICF and meet all study requirements
• History of morphologically confirmed AML (per World Health Organization [WHO] diagnostic criteria) with evidence of disease recurrence (>= 5% blasts consistent with prior disease) that occurs after allogeneic hematopoietic cell transplantation (HCT). Patients transplanted for another indication (e.g., myelodysplastic syndrome/chronic myelomonocytic leukemia [MDS/CMML]) who relapse with AML are eligible to enroll
• White blood cells (WBC) must be less than 25,000/ul for at least three days prior to cycle 1, day 1 (C1D1) (hydroxyurea allowed)
• A bone marrow biopsy must be performed and tissue collected for entrance to the trial
• Eastern Cooperative Oncology Group Performance Status of 0 - 2
• Alanine transaminase (ALT) serum glutamic pyruvic transaminase (SGPT) and/or aspartate aminotransferase (AST) serum glutamic-oxaloacetic transaminase (SGOT) less than or equal to 3x upper limit of normal (ULN)
• Total bilirubin < 1.5 x ULN
• Patients with Gilbert's syndrome (hereditary indirect hyperbilirubinemia) must have a total bilirubin of < 3 x ULN
• Calculated creatinine clearance >= 30 ml/min (per the Cockroft-Gault formula)
• Willingness to abide by all study requirements, including contraception, maintenance of a pill diary, and acceptance of recommended supportive care medications

You may not qualify if…

• Prior relapse or progression while receiving venetoclax or other commercially available or investigational BCL-2 inhibitor
• Anticancer therapy, including investigational agents =< 2 weeks or =< 5 half-lives of the drug, whichever is shorter, prior to C1D1. (Use of hydroxyurea is permitted)
• Inadequate recovery from toxicity attributed to prior anti-cancer therapy to =< Grade 1 (National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE] version [v]5.0), excluding alopecia or fatigue
• History of allogeneic HCT, or other cellular therapy product, within 3 months of signing consent
• Clinically active acute or chronic graft versus host disease (GVHD). Patients must be off calcineurin inhibitors for at least 4 weeks to be eligible
• Radiation therapy or major surgery within 3 weeks of signing consent
• Active, uncontrolled infection. Patients with infection under active treatment and controlled with antibiotics are eligible. Prophylaxis is acceptable
• Inability to tolerate oral medication, presence of poorly controlled gastrointestinal disease, or dysfunction that could affect study drug absorption
• Active documented central nervous system leukemia
• Concurrent treatment with a non-permitted concomitant medication
• Other malignancy IF currently being treated or likely to be treated in next 6 months except for basal or squamous cell carcinoma of the skin or cervical carcinoma in situ
• Pregnancy or breastfeeding females
• Known chronic alcohol or drug abuse
• Clinically significant cardiovascular disease with major event or cardiac intervention within the past 6 months (e.g. percutaneous intervention, coronary artery bypass graft, documented cardiac heart failure) as determined by the investigator
• Any other condition deemed by the investigator to make the patient a poor candidate for clinical trial and/or treatment with investigational agents
