Using statins to treat patients with clonal cytopenia and myelodysplastic syndromes

Official title: Pilot Study of Statins in Patients With Clonal Cytopenia of Undetermined Significance (CCUS) and Myelodysplastic Syndromes (MDS)

Run by Washington University School of Medicine · NCT05483010 · Data updated 2026-11-12

This study is testing whether the cholesterol-lowering drugs atorvastatin and rosuvastatin can help people with clonal cytopenia and lower-risk myelodysplastic syndromes feel better and slow down their disease.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a diagnosis of CCUS or lower-risk MDS who are transfusion independent.

Probably not a fit

Patients with higher-risk MDS or those requiring transfusions may not benefit from this study.

What this trial studies

This pilot study investigates the effects of statins, specifically atorvastatin and rosuvastatin, on patients diagnosed with clonal cytopenia of undetermined significance (CCUS) and lower-risk myelodysplastic syndromes (MDS). The study aims to assess changes in inflammatory biomarkers and variant allele frequency (VAF) of somatic mutations as indicators of response to statin therapy. Given the lack of FDA-approved treatments for these conditions, the research seeks to explore the potential of statins to improve patient outcomes and prevent disease progression. Participants must be transfusion independent and meet specific diagnostic criteria for CCUS or lower-risk MDS.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that may improve survival and quality of life for patients with CCUS and lower-risk MDS.

How similar studies have gone: While the use of statins in this context is novel, preclinical data suggest potential benefits, indicating that this approach is worth exploring.

Show full inclusion / exclusion criteria
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.
