This clinical trial focuses on studying the effects of certain cancer treatments on heart function. The diseases being studied are various types of cancer. The treatments involved in this study are two medications: nivolumab and pembrolizumab. These medications are part of a group of drugs known as immunotherapies, which help the body’s immune system fight cancer. Nivolumab is also known by the code names BMS936558 and ABP 206, while pembrolizumab is known by several code names, including Lambrolizumab and MK-3475.
The purpose of the study is to observe how the heart’s left ventricle, a chamber responsible for pumping blood, functions over time in patients receiving these treatments. This is done by monitoring patients in a specialized unit that focuses on the heart health of cancer patients, known as a Cardio-Oncology unit. The study will track changes in heart function using a specific measurement called the global longitudinal strain value, which helps assess how well the heart muscle is working.
Participants in the study will receive either nivolumab or pembrolizumab through an intravenous infusion, which means the medication is given directly into a vein. The study will last for a period of up to six months, during which the heart function of the participants will be regularly monitored. Some participants may receive a placebo, which is a substance with no active medication, to compare the effects of the actual treatments. The study aims to provide valuable information on how these cancer treatments might affect heart health, helping to improve care for future patients.
