Background: Immune checkpoint inhibitors (ICIs) are increasingly used in the treatment of cancer. However, immune-related adverse events are prevalent in patients receiving ICI therapy. A serious immune-related adverse event is ICI-myocarditis, which is complex to diagnose given that the significance of early symptoms and biomarker trajectories, such as high-sensitivity troponin T (hs-TnT) are unclear.

Obesity is an ongoing pandemic and is associated with the development of heart failure (HF), and especially HF with preserved ejection fraction. The definition of obesity is currently based on anthropometric measurements but neglects the location and molecular properties of excess fat. Important depots associated with HF development are subcutaneous adipose tissue and visceral adipose tissue, both located in the abdominal region, and epicardial adipose tissue (EAT) surrounding the myocardium.

Aims: Wild-type transthyretin cardiac amyloidosis (ATTRwt-CM) is an under-recognized aetiology of heart failure (HF), necessitating early detection for timely treatment. Our study aimed to differentiate patients with ATTRwt-CM from ATTRwt-negative HFpEF/HFmrEF patients by identifying and validating circulating protein biomarkers. In addition, we measured the same biomarkers in patients with cardiomyopathy due to light chain amyloidosis (AL)-CM to gain disease-specific insights.

Aims: Digoxin is the oldest drug in cardiovascular (CV) medicine, and one trial conducted >25 years ago showed a reduction in heart failure (HF) hospitalizations but no effect on mortality. However, later studies suggested that the dose of digoxin used in that trial (and other studies) may have been too high. The DECISION (Digoxin Evaluation in Chronic heart failure: Investigational Study In Outpatients in the Netherlands) trial will examine the efficacy and safety of low-dose digoxin in HF patients with reduced or mildly reduced left ventricular ejection fraction (LVEF) with a background of contemporary HF treatment.

Regulatory guidance for global drug development relies on animal studies to evaluate safety risks for humans, including risk of reproductive toxicity. Weight-of-evidence approaches (WoE) are increasingly becoming acceptable to evaluate risk. A WoE for developmental risk of monoclonal antibodies (mAbs) was evaluated for its ability to retrospectively characterize risk and to determine the need for further in vivo testing based on the remaining uncertainty.

Embryofetal development (EFD) studies are performed to characterize risk of drugs in pregnant women and on embryofetal development. In line with the ICH S5(R3) guideline, these studies are generally conducted in one rodent and one non-rodent species, commonly rats and rabbits. However, the added value of conducting EFD studies in two species to risk assessment is debatable.
