Myelodysplastic Syndromes, Myeloproliferative Chronic Myelomonocytic Leukemia
Conditions
Brief summary
To learn if the combination of cladribine, cytarabine, venetoclax, and azacitidine can help to control higher-risk myelodysplastic syndrome (MDS) with excess blasts and/or higher-risk chronic myelomonocytic leukemia (CMML).
Detailed description
Primary Objectives: * To determine the efficacy, safety and tolerability of the combination of cladribine, cytarabine and venetoclax in higher-risk MDS with excess blasts and higher-risk CMML. * MDS relapsed cohort (Cohort A, N=20): MDS with Int-2 or High risk IPSS and \>5% blasts with no response after 6 cycles of azacitidine, decitabine, guadecitabine, CC-486 or ASTX727 (decitabine/cedazuridine) or relapse or progression after any number of cycles * CMML relapsed cohort (Cohort B, N=10): CMML 1 or 2 with no response after 6 cycles of azacitidine, decitabine, guadecitabine, CC-486 or ASTX727 (decitabine/cedazuridine) or relapse or progression after any number of cycles * MDS HMA-naïve cohort (Cohort C, N=20): MDS with Int-2 or High risk by IPSS and \>10% blasts OR diagnosis * CMML HMA-naïve cohort (Cohort D, N=10): CMML-2; OR CMML-1 with at least one of the following high-risk features: extramedullary disease, splenomegaly of \>5cm below costal margin, platelets \<100x109/L, Hgb level \<10g/dL, WBC \>13x109/L, clonal cytogenetic abnormality (other than monosomy Y). Secondary Objectives: * To evaluate responses by 2015 IWG MDS/MPN response criteria in patients with MDS/MPN and by 2023 IWG response criteria in all patients (Appendix). * To assess overall survival (OS), duration of response, leukemia-free survival (LFS), and relapse-free survival (RFS). * To evaluate proportion of transplant-candidate patients bridged to allogeneic stem-cell transplant. * Correlative studies including correlation of response with disease subtype and genomic profile. * To evaluate changes in clonal composition and VAF of identified mutations with therapy.

Diagnosis of MDS or CMML by WHO and: * MDS relapsed cohort (Cohort A): MDS with IPSS-R score \>3.5 and \>5% blasts with no response after 6 cycles of azacitidine, decitabine, guadecitabine or ASTX727 (decitabine/cedazuridine) or relapse or progression after any number of cycles * CMML relapsed cohort (Cohort B): CMML 1 or 2 with no response after 6 cycles of azacitidine, decitabine, guadecitabine or ASTX727 (decitabine/cedazuridine) or relapse or progression after any number of cycles * MDS HMA-naïve cohort (Cohort C): MDS with IPSS-R score \>3.5 and \>/= 10% blasts * CMML HMA-naïve cohort (Cohort D): CMML-2; OR CMML-1 with at least one of the following high-risk features: extramedullary disease, splenomegaly of \>5cm below costal margin or by sonographic volumetric assessment, platelets \<100x109/L, Hgb level \<10g/dL, WBC \>13x109/L, clonal cytogenetic abnormality (other than monosomy Y) or high risk mutations (ASXL1, RUNX1, SETBP1, BRAF, NRAS, KRAS, PTPN11, NF1, CBL). * MDS/MPN relapsed cohort (Cohort E): MDS/MPN-NOS, MDS/MPN with neutrophilia (atypical CML) or MDS/MPN-RS-T with \>5% blasts with no response after 6 cycles of azacitidine, decitabine, guadecitabine or ASTX727 (decitabine/cedazuridine) or relapse or progression after any number of cycles * MDS/MPN HMA-naïve cohort (Cohort F): MDS/MPN-NOS or MDS/MPN with neutrophilia (atypical CML) with * \>/=10% blasts or * with \>5% blasts at least one of the following high-risk features: splenomegaly \>5cm below costal margin, WBC \>13x109/L, high risk cytogenetic or molecular features (ASXL1, SETBP1, i(17q), TP53) or * who might not be deemed to benefit from HMA therapy due to proliferative or extramedullary disease. 3. Eastern Cooperative Oncology Group (ECOG) performance status of \</= 2 4. Creatinine clearance \> 30 ml/min no end/stage renal disease (using Cockcroft-Gault) 5. Adequate hepatic function with total bilirubin 2x ULN, AST or ALT 2.5 xULN unless deemed to be due to underlying disease involvement. 6.
