This phase II trial tests how well canakinumab works to prevent progression to cancer in patients with clonal cytopenias of unknown significance (CCUS). CCUS is a blood condition defined by a decrease in blood cells. Blood cells are composed of either red blood cells, white blood cells, or platelets. In patients with CCUS, blood counts have been low for a long period of time. Patients with CCUS also have a mutation in one of the genes that are responsible for helping blood cells develop. The combination of genetic mutations and low blood cell counts puts patients with CCUS at a higher risk to develop blood cancers in the future. This transformation from low blood cell counts to cancer may be caused by inflammation in the body. Canakinumab is a monoclonal antibody that may block inflammation in the body by targeting a specific antibody called the anti-human interleukin-1beta (IL-1beta).
PRIMARY OBJECTIVE: I. To evaluate the length of time until development of a myeloid neoplasm (ie myelodysplastic syndrome \[MDS\], myeloproliferative neoplasm \[MPN\], chronic myelomonocytic leukemia \[CMML\], or acute myeloid leukemia \[AML\]) in high-risk clonal cytopenia of undetermined significance (CCUS) patients receiving canakinumab as therapeutic intervention compared to the control arm. SECONDARY OBJECTIVES: I. To determine the effect of canakinumab on hematological overall response rate. II. To determine the effect of canakinumab on complete hematological response rate. III. To determine the effect of canakinumab on response duration. IV. To determine the effect of canakinumab on overall survival. V. To determine the effect of canakinumab on mutational burden. VI. To determine the effect of canakinumab on infection-related adverse events. VII. To determine the effect of canakinumab on recovery of blood cell populations. VIII. To determine the effect of canakinumab on cardiovascular episodes compared to a control arm. IX. Patient reported outcomes will be collected using European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C3). EXPLORATORY OBJECTIVES: I. To quantify changes in the bone marrow (BM) microenvironment according to immune cell constitution and cytokine levels over the course of canakinumab treatment compared to a control arm. II. To characterize the inflammatory milieu in peripheral blood (PB) and BM samples by serial measurement and characterization of key cytokines (IL-1, IL-2, IL-6, TNF alpha and beta, and IFN-gamma), sensitivity of patient samples to these cytokines and relationships to various genes involved in clonal hematopoiesis. III. To determine the dynamics of change in clone size of various CH genes in serial patient treatment and control samples, during the study, by a variety of assays including single cell sequencing, copy number alterations, and variant allele frequency (VAF) measurement to characterize differences in disease evolution. IV. To collect serial measurement of immune cell populations in PB and BM of serial patient treatment and control samples, during the study, to characterize various immune cells involving both the innate and adaptive immune system including natural killer (NK) cell, T cell subsets namely effector, regulatory and memory T cells as well as various cell surface molecules such as checkpoint modulators (PD-1/PD-L1/TIM-3, LAG-3). V. To understand the effect of global effects on the BM microenvironment of CH status/post (s/p) canakinumab treatment compared to the control patients using ribonucleic acid (RNA) sequencing and global methylation assays to further characterize unique genomic signatures in these patients. OUTLINE: Patients are randomized to one of two arms. ARM I: Patients receive canakinumab subcutaneously (SC) on study. ARM II: Patients receive placebo SC on study. All patients also undergo echocardiogram (ECHO) and chest x-ray during screening, collection of blood samples during screening and follow up, and bone marrow biopsy and aspiration throughout the trial.

RECRUITINGTime to overt myeloid malignancy
Will be estimated with the non-parametric Kaplan-Meier method to compute the median time as well as the percentage of study participants with a diagnosed hematologic malignancy of myelodysplastic syndrome (MDS), myeloproliferative neoplasm (MPN), chronic myelomonocytic leukemia (CMML)/ acute myeloid leukemia (AML) at landmark time points (e.g., 1-year, 2-years) with corresponding 95% confidence intervals. Since this method will censor patients who die without having developed MDS/MPN/CMML/AML, we will also compute the cumulative incidence of overt myeloid malignancy that accounts for the competing risk of death in the absence of a hematologic malignancy. All randomized patients will be included in the primary endpoint analysis in the arm to which they were randomized (ie, intent-to-treat population).
Time frame: From the date of randomization until the first date of overt myeloid malignancy diagnosis, assessed up to 6 years
Hematological overall response rate
Number of patients that achieve response divided by the number or randomized patients. Will be summarized using the method of Kaplan-Meier but also using the cumulative incidence function which would treat death in the absence of documented relapse as a completing risk.
Time frame: 6 month assessment
Complete hematological response rate
Number of patient that achieve complete response divided by the number of randomized patients. Will be summarized using the method of Kaplan-Meier but also using the cumulative incidence function which would treat death in the absence of documented relapse as a completing risk.
Time frame: 6 month assessment
Duration of hematological response
Will be summarized using the method of Kaplan-Meier but also using the cumulative incidence function which would treat death in the absence of documented relapse as a completing risk.
Time frame: From the date of first documented hematological response until the date of documented diagnosis of MDS, MPN, CMML, or AML, assessed up to 6 years
Overall survival
Will be estimated using the method of Kaplan-Meier and estimates at landmark time points (e.g., 1-year, 2-years) will be provided with corresponding 95% confidence intervals.
Time frame: From the date of registration until the date of death from any cause, assessed up to 6 years
Changes in variant allele frequencies (VAFs) of somatic mutations
Will be assessed by bone marrow biopsy (BMBx) samples with next generation sequencing (NGS). VAFs will be analyzed as a continuous variable and as the proportion of patients with at least a 50% of reduction in VAFs of somatic mutations relative to baseline using an Ion Torrent platform.
Time frame: Up to 6 years
Infection-related adverse event rates
The number of patients who have an adverse event of interest divided by the number of patients who have adverse events assessed.
Time frame: Up to 6 years
Recovery of blood cell populations
Changes in the percentages of lymphocytes and specific sub-types (ie T-cells) as well as erythroid, platelet, and neutrophil response via 2016 World Health Organization (WHO) International Working Group (IWG) hematological improvement criteria before and after therapy as assessed in bone marrow (BM) and hematological samples.
Time frame: Up to 6 years
Cardiovascular episodes
The number of patients who has a cardiovascular event of interest divided by the number of patients who have adverse events assessed.
Time frame: Up to 6 years
Patient reported outcomes
Outcomes reported using EORTC QLQ-C30 and compared between the two arms.
Time frame: Up to 6 years
