Abstract Purpose  Small-molecule protein kinase inhibitors (PKIs) have substantially improved clinical outcomes of various diseases. However, some studies suggested these agents might induce acute kidney injury (AKI). This study was designed to comprehensively assess the adverse events of AKI in real-world patients receiving small-molecule PKIs using the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). Methods  The FAERS data between 2004 and 2019 were extracted to describe the characteristics of AKI cases after the use of small-molecule PKIs approved by the FDA. The reporting odds ratio (ROR) with 95% confidence interval (CI) for AKI was calculated for each small-molecule PKI agent. A disproportionality signal was defined when the lower limit of 95% CI > 1. Results  Among the 462,020 adverse event reports for small-molecule PKIs, 9970 (2.16%) were identified as AKI cases. The median AKI onset time was 32 (interquartile range 11–124) days after the initiation of small-molecule PKI treatment. A total of 61.38% and 26.04% of AKI cases resulted in hospitalization and death, respectively. Based on RORs, 14 of 52 small-molecule PKIs yielded disproportionality signals for AKI, including six VEGFR inhibitors, three mTOR inhibitors and five small-molecule PKIs with other targets. The agents with the highest AKI RORs were entrectinib (ROR 6.40, 95% CI 2.23, 18.34), sirolimus (ROR 3.76, 95% CI 3.45, 4.09), and cobimetinib (ROR 3.40, 95% CI 2.69, 4.28). Conclusion  Analysis of the FAERS data helped identify the small-molecule PKIs that were most frequently reported for AKI. Further investigations are needed to confirm these potential risks.

The last two decades have witnessed unprecedented success in the development of protein kinase inhibitors (PKIs). As of December 2019, a total of 52 small-molecule PKIs with various targets have been approved by the US Food and Drug Administration (FDA) (Online Resource 1) [1, 2]. These new agents have brought promisi
