nintedanib and Blood-Coagulation-Disorders

Nintedanib is a synthetic orally active tyrosine kinase inhibitor, whose main action is to inhibit the receptors of the platelet-derived growth factor, fibroblast growth factor and vascular endothelial growth factor families. The drug also affects other kinases, including Src, Flt-3, LCK, LYN. Nintedanib is used in the treatment of idiopathic pulmonary fibrosis, chronic fibrosing interstitial lung diseases and lung cancer. The mechanism of action suggests that nintedanib should be considered one of the potential agents for inhibiting and revising the fibrosis process related to COVID-19 infections. Due to the known induction of coagulation pathways during COVID-19 infections, possible interaction between nintedanib and anticoagulant seems to be an extremely important issue. In theory, nintedanib could increase the bleeding risk, thrombosis and lead to thrombocytopenia. The data from clinical trials on the concomitant use of nintedanib and antithrombotic agents is very limited as this patient group was within the standard exclusion criteria. Nintedanib is an important therapeutic option, despite its interaction with anticoagulants. If anticoagulant therapy is necessary, the more effective and safer option is the concomitant administration of DOACs and nintedanib, especially when drug-monitored therapy will be used in patients at high risk of bleeding complications.

Novel agents to reduce angiogenesis by targeting vascular endothelial growth factor and other proangiogenic signaling pathways are being developed for advanced nonsmall cell lung cancer. Antibody-based therapies (e.g., aflibercept) and multitargeted tyrosine kinase inhibitors (e.g., sorafenib, sunitinib, and BIBF 1120) are being evaluated in phase III clinical trials. Some antiangiogenic agents have demonstrated distinct profiles in producing a variety of nonhematologic toxicities, including bleeding/hemorrhage, venous and arterial thromboembolic events, gastrointestinal perforation, hypertension, and proteinuria. Elucidating the molecular basis of these toxicities may lead to clinical benefits by improving patient selection and allowing for the development of effective prevention and management strategies.
