Clonal Hematopoiesis of Indeterminate Potential and Infarct Severity in ST-Elevation Myocardial Infarction

Clonal Hematopoiesis of Indeterminate Potential (CHIP) refers to the age-related expansion of hematopoietic stem cell clones carrying somatic mutations in leukemia-associated driver genes (e.g., DNMT3A, TET2, ASXL1) in the absence of a hematological malignancy. CHIP has been identified as an independent cardiovascular risk factor associated with increased rates of myocardial infarction, stroke, and cardiovascular mortality, likely mediated through enhanced inflammatory signaling in mutant macrophages and monocytes. ST-elevation myocardial infarction (STEMI) is a life-threatening emergency requiring immediate reperfusion by primary percutaneous coronary intervention (PCI). Despite successful reperfusion, adverse cardiac remodeling and heart failure may occur depending on myocardial injury severity, microvascular obstruction (MVO), and intramyocardial hemorrhage (IMH) - phenomena substantially driven by ischemia-reperfusion injury and the inflammatory response. The CHIP in STEMI study is a prospective, observational, single-center cohort study at the Medical University of Innsbruck investigating whether CHIP - detected by targeted next-generation sequencing - is associated with greater infarct severity and worse cardiac outcomes in STEMI patients undergoing primary PCI. The primary endpoint is the presence of MVO and/or IMH on cardiac MRI (CMR) at 5±2 days post-PCI. Secondary endpoints include infarct size, left and right ventricular function, major adverse cardiovascular events (MACE), and immune cell transcriptome profiling by single-cell RNA sequencing. 350 patients (18-75 years, minimum 90 female) will be enrolled over 36 months and followed for 4 years (2026-2030).

Clonal Hematopoiesis Chemotherapy and Radiation Effects Study

The goal of the Clonal Hematopoiesis Chemotherapy and Radiation Effects (CH CARE) Study is to understand how the presence or absence of clonal hematopoiesis (CH) influences outcomes in people receiving chemotherapy and radiation for solid cancers. The study will collect biospecimens and clinical information. These data will be used to define clinical and molecular features that predict the presence of high-risk clonal hematopoiesis (CH) in patients exposed to cytotoxic anti-cancer therapy. Predictive features will be utilized to identify populations of cancer patients and survivors who are at the highest risk of developing therapy-related myeloid neoplasms (t-MNs). Ultimately this study will result in the development of a novel novel risk prediction algorithm for t-MNs in patients with solid cancers and drive potential therapeutic approaches to intercept progression from CH to often fatal t-MNs.

A Study to Investigate the Efficacy, Safety, and Tolerability of DFV890 and MAS825 for Inflammatory Marker Reduction in Adult Participants With Coronary Heart Disease and Clonal Hematopoiesis of Indeterminate Potential (CHIP)

This Phase 2a clinical trial evaluated the effectiveness, safety, and tolerability of increasing dose strengths of an oral daily medication, DFV890, administered for 12 weeks, or a single s.c. dose of MAS825, to reduce key markers of inflammation related to CVD risk, such as IL-6 and IL-18, in approximately 28 people with known coronary heart disease and TET2 or DNMT3A CHIP (variant allele frequency \[VAF\] ≥2%).
