title: Troponin measurements during drug development--considerations for monitoring and management of potential cardiotoxicity: an educational collaboration among the Cardiac Safety Research Consortium, the Duke Clinical Research Institute, and the US Food and Drug Administration.
abstract: Drug-induced cardiac toxicity is a recognized challenge in development and implementation of pharmacotherapy. Appropriate biomarkers are needed to detect these abnormalities early in development and to manage the risk of potentially cardiotoxic drugs or biologic agents. Circulating cardiac troponin (cTn) is the most widely used biomarker for detection of myocardial injury. Although most commonly used to detect myonecrosis in the setting of ischemia, cTns are also elevated with other acute and chronic disease processes, including heart failure, renal failure, sepsis, pulmonary embolic disease, and many others. High-sensitivity assays for both cTnI and cTnT are now available that achieve acceptable imprecision (coefficient of variation <10%) at the 99th percentile of a normal reference population. Even more sensitive assays are being developed that detect cTn in ranges that are near the level of normal cellular turnover (apoptosis). These properties of cTn and the continuing evolution of highly sensitive assays position cTn as a potentially uniquely informative marker for early detection of cardiac toxicity. This article summarizes collaborative discussions among key stakeholders in the Cardiac Safety Research Consortium about the use of cTn monitoring in drug development.
