Wound healing complications with lenvatinib identified in a pharmacovigilance database

The U.S. Food and Drug Administration (FDA) has approved several vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors, including lenvatinib, for thyroid and renal malignancies. Inhibition of the VEGFR signaling pathway impairs angiogenesis and can disrupt wound healing. The objective of this work was to evaluate wound healing complications as a potential safety risk for patients treated with lenvatinib. We searched the FDA Adverse Event Reporting System (FAERS) database for postmarketing reports of wound healing complications with lenvatinib between 13 February 2015 (FDA approval date) and 15 February 2017. The search identified nine FAERS cases of lenvatinib-associated wound healing complications that were not previously reported in the medical literature. Seven cases involved postoperative wound healing complications, such as impaired healing or wound dehiscence. In our case series, the reported time to identification of delayed wound healing from tissue injury or surgery varie...
