Abstract
The development of novel treatments has improved cancer outcomes but may result in cardiovascular toxicities. Traditional approaches to clinical trial safety evaluation have limitations in their ability to detect signals of cardiovascular risk. Mechanisms to increase power and specificity to clarify cardiovascular safety are required. However, implications include increased costs and slower development. The Cardiovascular Safety Research Consortium facilitated stakeholder discussions with representation from academia, industry, and regulators. A think tank was assembled with the aim of providing recommendations for improved collection and reporting of cardiovascular safety signals in oncology trials. Two working groups were formed. The first focuses on incorporation of consensus definitions of cardiovascular disease into the Common Terminology Criteria for Adverse Events used in oncology trial reporting. The second group considers methods for ascertainment and adjudication of cardiovascular events in cancer trials. The overarching aim of this primer is to improve understanding of the potential cardiovascular toxicities of cancer therapies.
