Cytopenia(s) defined as the presence of ≥ 1 of the following:\n\n  * Hemoglobin (Hgb) \\\u003C12 g\u002FdL for women and \\\u003C13g\u002FdL for men\n  * Absolute neutrophil count (ANC) \\\u003C 1.8 × 109\u002FL\\*\n  * Platelet count (Plt) \\\u003C150 × 109\u002FL \\*Patients known to have a Duffy-null genotype must have anemia (Hgb \\\u003C 12g\u002FdL for women, Hgb \\\u003C13g\u002FdL for men) and\u002For thrombocytopenia (Plt \\\u003C 150 × 109\u002FL) to be eligible for this study.\n\n    * 1 pathogenic variant detected in any myeloid driver gene with a VAF of at least 0.02 (2%) identified by local next generation sequencing (NGS) of peripheral blood or bone marrow sample within 3 months from screening bone marrow biopsy.\n* Participants must have a high risk score per the Clonal Hematopoiesis Risk Calculator (CHRS). See APPENDIX C for calculation.\n* Screening bone marrow biopsy must not be diagnostic of any overt hematologic malignancy by morphologic assessment and must be consistent with a diagnosis of clonal cytopenia of unknown significance (CCUS) as determined by multi-institutional hematopathology review.\n* ECOG performance status 0-2 (see Appendix A).\n* Participants must meet the following organ function as defined below:\n\n  * Serum aspartate aminotransferase\u002Fserum glutamic oxaloacetic transaminase (AST\u002FSGOT) and alanine aminotransferase (ALT\u002FSGPT) ≤3x upper limit of normal (ULN).\n  * Serum total bilirubin \\\u003C1.5x ULN. Higher levels are acceptable if these can be attributed to ineffective erythropoiesis or Gilbert's syndrome. In these cases, approval from the study Sponsor-Investigator is required.\n  * Creatinine clearance greater than 40 mL\u002Fmin based on the Cockcroft-Gault glomerular filtration rate estimation.\n* Ability to understand and the willingness to sign a written informed consent document.\n* For participants of the early pharmacologic intervention cohort: women of childbearing potential must use highly effective contraception during treatment for at least 6 months after the last dose and males with female partners of reproductive potential should use effective contraception during treatment and for 3 months after the last dose.\n\nExclusion Criteria:\n\n* Concurrent primary malignancy requiring active cytotoxic chemotherapy and\u002For ionizing radiation therapy.\n* Known inherited bone marrow failure disorder and\u002For germline predisposition to hematologic malignancy.\n* Receipt of anti-cancer therapy including any cytotoxic chemotherapy, ionizing radiation therapy, immunomodulatory agents such as lenalidomide, and targeted anti-cancer therapies including PARP inhibitors within the last 6 months. Patients with complete surgical resection of a tumor are not excluded from this study.\n* Anti-cancer therapy, including any cytotoxic chemotherapy, ionizing radiation therapy, immunomodulatory agents such as lenalidomide and targeted agents such as PARP inhibitors, planned in the next 6 months. Patients on hormonal adjuvant therapy for nonmetastatic breast and prostate cancer or other minimally-myelosuppressive maintenance therapies for non-metastatic cancer may be eligible at the discretion of the study PI.\n* Diagnosis of MDS, MPN, CMML, AML or any other hematolymphoid malignancy in the patient's lifetime. This includes individuals with MDS-defining chromosomal abnormalities identified via conventional karyotype or FISH.\n* Presence of a concurrent hematologic malignancy precursor state, such as smoldering multiple myeloma (SMM), and smoldering Waldenstrom's macroglobulinemia.\n* Presence of an early-stage hematologic precursor state-such as monoclonal gammopathy of undetermined significance (MGUS) and monoclonal B cell lymphocytosis (MBL).\n* Active uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing signs\u002Fsymptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and\u002For other treatment).\n* Recent (within 3 months) vaccination with any live attenuated vaccine or vaccination with live attenuated vaccine planned during the next 15 months. \\*Live attenuated vaccines include measles, mumps, rubella (MMR combined vaccine), rotavirus, smallpox, chickenpox, and yellow fever.\n* Laboratory evidence indicative of clinically significant red cell hemolysis.\n* Hypersplenism and\u002For evidence of portal hypertension on physical exam or imaging.\n* Pregnant or lactating.","ALL","18 Years",{"count":19,"type":20},108,"ESTIMATED","INTERVENTIONAL",[23],"EARLY_PHASE1","This research is being done to find out more about the potential risks and benefits of early treatment in participants with high risk Clonal Cytopenia of Unknown Significance (CCUS).
