Therapeutic drug monitoring of small molecule kinase inhibitors in oncology in a real‐world cohort study: does age matter?

Abstract

In this real-world study, exposure to most included KIs was comparable in older and younger patients, except for dabrafenib, which showed higher exposure in older patients. In the absence of an absolute target for this KI, clinical relevance remains unclear. For all other included KIs, our data suggest no clinically relevant influence of older age on KI exposure.
