Crizotinib: Renal Safety Evaluation
Anaplastic lymphoma kinase 1 (ALK 1) is a member of the insulin receptor tyrosine kinase family. Crizotinib is a small molecule inhibitor available for clinical use, which is found within the ALK family of drugs. Several other ALK 1 inhibitors are currently being evaluated in preclinical and clinical trials. Crizotinib is approved for the treatment of advanced ALK positive non-small cell lung cancer (NSCLC). However, this drug is associated with various renal adverse effects. Treatment with crizotinib appears to be associated with pseudo- and true acute kidney injury. Peripheral edema and rare electrolyte disorders are also described with this ALK inhibitor. Finally, crizotinib also appears to increase the risk for the development and progression of renal cysts. This review focuses on the mechanism of action, clinical indications, pharmacology, and adverse renal effects of crizotinib.
