Cancer patients who are ineligible for clinical trials receive immune checkpoint inhibitors (ICI) at greater rates than patients who are trial eligible despite no survival benefit, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania. The study, published in JAMA Oncology, suggests that the positive results for phase 3 clinical trial participants receiving ICI treatment may not translate to patients who are ineligible for trials due to factors such as organ dysfunction.
