Major Research Findings

Axitinib is a potent vascular endothelial growth factor receptor (VEGFR) inhibitor that has been shown to have antitumor activity against a variety of cancers, including renal cell carcinoma (RCC), medulloblastoma, glioblastoma, and chronic myeloid leukemia. 4 , 7 , 11 , 13 , 9 , 12 , 18 , 1 . For example, in a study of patients with metastatic RCC, axitinib was found to be an effective second-line treatment option, with a concordance index value of 0.84. 3 . Axitinib has also been shown to improve survival in patients with medulloblastoma, especially when combined with other drugs like gemcitabine. 8 . Additionally, axitinib has shown promise in treating interstitial cystitis, a painful bladder condition. 2 . However, axitinib can also have serious side effects, including hypertension, proteinuria, cardiovascular damage, and liver and kidney dysfunction. 4 , 5 , 15 . These side effects can limit the effectiveness of axitinib and reduce the quality of life of patients.

Several studies have investigated strategies to mitigate the side effects of axitinib while maintaining its antitumor activity. For instance, losartan, an angiotensin receptor blocker, has been shown to reduce the side effects of axitinib without compromising its antitumor efficacy. 5 . Similarly, a selenium substitute of axitinib has been developed that reduces side effects and maintains anti-renal tumor activity. 4 . Furthermore, combining axitinib with other anticancer drugs, such as irinotecan or doxorubicin, has shown synergistic antitumor effects. 17 , 13 . Axitinib can also interact with other drugs, such as loperamide, increasing its exposure and potential for adverse effects. 10 .
