Purpose

Patients with clonal cytopenia of undetermined significance (CCUS) and lower-risk myelodysplastic syndromes (MDS) have a life expectancy of 5 to 10 years. Mortality in these patients results from progression of disease to higher-risk MDS or acute myeloid leukemia (AML) and cardiovascular events. Currently there are no FDA-approved treatments with the potential to improve survival of patients with CCUS and lower-risk MDS. Statins are an appealing class of drugs to consider in this situation as preclinical data support their potential to suppress progression of myeloid malignancy, and they have a well-established role in prevention of major cardiovascular events. This is a pilot study to explore the role of statins in treatment of patients with CCUS and lower-risk MDS. In this study, change in inflammatory biomarkers and variant allele frequency (VAF) of somatic mutations will be used as a surrogate marker of response to statin therapy. The hypothesis is that the use of statins at diagnosis of CCUS or lower-risk MDS will reduce inflammation and delay or prevent the expected increase in the VAF of somatic mutations over time.

Inclusion Criteria

  • Diagnosis of CCUS or lower-risk MDS as defined below: - CCUS is defined as the presence of somatic mutation(s) in recurrently mutated genes identified through the clinical MyeloSeq assay with a VAF ≥ 2% in the absence of bone marrow morphology/cytogenetic changes diagnostic of MDS PLUS unexplained persistent cytopenia in at least one lineage for at least 6 months: - Hemoglobin < 11.3 g/dL in females or < 13 g/dL in males - ANC < 1.8 x 109/L - Platelets < 150 x 109/L - MDS is defined using the WHO 2016 definition and classified into lower-risk if IPSS-R score is ≤ 3.5 . Lower-risk MDS will be required to have at least one mutation in a recurrent mutated gene with a VAF ≥ 2%. - Patient must be transfusion independent. - At least 18 years of age. - Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria

  • CCUS patients with cytogenetic change alone. - Current or prior use of disease-modifying therapy (e.g., lenalidomide, Luspatercept, Imitelstat, HMAs, venetoclax) with any dose within the last 3 months, with the exception of concurrent use of erythropoetin stimulating agents - Prior use of a statin within 1 year prior to start of treatment. - A history of other malignancy with the exception of malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence active of disease. - Currently receiving any investigational agent for CCUS/MDS. The minimum interval between the last dose of investigational agent used for CCUS/MDS and Day 1 of this trial should be 5 half-lives of the investigational agent. - A history of allergic reactions or intolerance attributed to compounds of similar chemical or biologic composition to atorvastatin, rosuvastatin, any other statin, or other agents used in the study. - Uncontrolled intercurrent illness including, but not limited to, symptomatic infection, sepsis, or active liver disease (acute liver failure, decompensated cirrhosis, or persistent elevation in ALT or AST > 3 x ULN), or any other comorbidity that would preclude statin use based on FDA recommendation. - Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry. - Patients with HIV and HCV are not eligible for the trial if they are concomitantly receiving active treatment for HIV/HCV given the concern for potential drug interactions. The minimum interval between the last dose of antiviral and enrollment into the study should be 28 days or 5 half-lives of the antiviral drug, whichever is longer. The liver function profile of eligible HIV/HCV patients must be within the acceptable limits.

Experimental
Atorvastatin 		- Choice of statin is at the discretion of the treating physician and may depend on insurance approval. - Atorvastatin dosing starts at 80 mg once daily. - In the absence of disease progression or intolerable side effects, patients may receive up to 12 months of treatment. - If a patient switches statins due to toxicity, treatment time is still limited to 12 months total (ie, if a patient receives 6 months of atorvastatin and switches to rosuvastatin, the duration of rosuvastatin will be no more than 6 months).
  • Drug: Atorvastatin
    Atorvastatin is commercially available.
