It is the most common type of acute leukemia, particularly in adults. There are around 20,000 cases of acute myeloid leukemia diagnosed in the United States every year. Despite the recent significant progress in the understanding of acute myeloid leukemia leading to the development of new therapies, significant challenges remain. The initial treatment for acute myeloid leukemia involves using therapies aimed at reducing the disease burden in the bone marrow to the lowest possible level (a state known as disease remission). This is usually followed by consolidation treatment aimed at curing the disease. The initial treatment involves high intensity chemotherapy in younger adults who can tolerate these therapies and low intensity therapies for older adults or those with other medical conditions that prohibit them from receiving high intensity chemotherapy. The consolidation therapy involves either more chemotherapy or a bone marrow transplant. In the recent years, a treatment regimen consisting of two drugs; Azacytidine and Venetoclax has become the standard of care for low intensity therapy intended for older adults. Despite significant improvement in outcomes of acute myeloid leukemia in older adults after the introduction of Azacytidine/Venetoclax, yet 40% of patients who receive this treatment will either be refractory to it or relapse after an initial remission. Those whose leukemia relapses after Azacytidine/Venetoclax treatment are left with very few treatment options and have a dismal prognosis. Based on previous laboratory studies, certain subtypes of acute myeloid leukemia tend to not respond as well to Azacytidine/Venetoclax therapy and have a better chance of responding to the treatment regimen the investigators are proposing in this study. The study treatment regimen consists of 3 drugs; Cladribine, low dose Cytarabine and Venetoclax. Demonstrating efficacy of the study regimen in treatment of relapsed/refractory acute myeloid leukemia, after prior Venetoclax therapy, will provide another treatment option for those with a relapsed/refractory disease who wish to continue receiving therapy.', 'detailedDescription': 'Among the main mechanisms implicated in acute myeloid leukemia (AML) relapse after treatment with Venetoclax is upregulation of myeloid cell leukemia 1 (MCL-1) in AML cells with their survival becoming less dependent on the Venetoclax target, B-cell leukemia/lymphoma 2 (BCL-2). Leukemic stem cells (LSCs) in AML with monocytic differentiation are significantly more resistant to treatment with azacytidine/venetoclax being less dependent on BCL-2 and demonstrating preferential reliance on MCL-1 for survival. Cladribine, combined with Venetoclax in preclinical studies have shown efficacy in overcoming resistance to Venetoclax by downregulating MCL-1, particularly in AML with monocytic features and/or rat sarcoma oncogene (RAS) mutations.\n\nThe investigators propose to use the cladribine, low-dose cytarabine and venetoclax (CAV) regimen in patients with relapsed/refractory or secondary AML (transformed from myelodysplastic syndrome \\[MDS\\], myeloproliferative neoplasm \\[MPN\\] or MDS/MPN overlap) who were previously treated with a venetoclax-containing regimen, whose disease lacks molecular targets with approved therapies. CAV is a medium intensity regimen that has demonstrated acceptable safety and tolerability in older patients with AML and/or those who are unfit for intensive therapies\n\nObjective:\n\nThe primary objective is to estimate the rate of composite complete remission (CRc) in participants with relapsed/refractory or secondary AML who are treated with cladribine, low-dose cytarabine and venetoclax after prior treatment with a venetoclax-containing regimen.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': '* Inclusion Criteria\n\n * Participants with relapsed/refractory AML (according to European LeukemiaNet 2022 Criteria) after treatment with a Venetoclax-containing regimen.\n * Participants with MDS, MPN, or MDS/MPN overlap who develop secondary AML after treatment with a Venetoclax-containing regimen.\n * Prior therapy with hydroxyurea or emergency use of Cytarabine (up to 1 gm total dose) for cytoreduction is allowed.\n * Prior hematopoietic stem-cell transplant (HSCT) and/or donor lymphocyte infusion (DLI) are allowed if at the time of relapse ≥ 90 days have passed from the date of the last stem cell transplant (90-day duration not required for DLI).\n * Age ≥ 18 years old.\n * Eastern Oncology Group (ECOG) performance status of ≤ 2\n * Participants must agree to take the following reproductive precautions:\n\n * Negative urine pregnancy test within one week prior to starting the study therapy for all women of childbearing potential.\n * Participants who could become pregnant should use effective contraception during therapy and for 6 months after the last dose of study treatments.
