Determination of Drug Levels for Pharmacotherapy of Heart Failure

Status Not yet recruiting

Clinical Trial Summary

The aim of this study is to determine whether and how serum concentrations of the used medicinal products, including their metabolites, correlate with selected clinical indicators of heart failure (NT-proBNP concentration, 6-minute walk test, quality of life questionnaire, echocardiographic parameters, hospitalization for HFrEF, length of survival).

Clinical Trial Description

The prevalence of chronic heart failure increases with age, and this disease is one of the most common reasons for hospitalization in the elderly. In order to reduce the number of exacerbations, the frequency of hospitalizations, morbidity and mortality and improve the overall quality of life, the treatment strategy should be individually set for each patient, regularly monitored and reviewed. Patients with chronic heart failure show significant differences in the pharmacokinetics of both cardiovascular and non-cardiovascular drugs. At the same time, they tend to be exposed to other prescribed medicinal products, and therefore there is an increased risk of drugs interactions. These findings emphasize the need for comprehensive pharmacokinetic studies in patients with chronic heart failure, together with the exploration of the potential benefit of biomarkers suitable for monitoring the clinical status of patients. Pharmacotherapy of chronic heart failure with reduced ejection fraction (Heart Failure with Reduced Ejection Fraction - HFrEF) currently consists of beta-blockers together with mineralocorticoid receptor antagonists, the combination of sacubitril/valsartan drugs and sodium-glucose transporter 2 inhibitors. Although the recommendation of therapeutic drug monitoring (TDM) in patients with chronic heart failure has not yet been established, its introduction can serve as an effective tool for detecting changes in the pharmacokinetics of drugs used, objectifying drug interactions and ascertaining patient adherence to treatment, thereby becoming part of safe personalized pharmacotherapy of this disease. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
