Potential drug repurposing of ruxolitinib to inhibit the JAK/STAT pathway for the treatment of patients with epithelial ovarian cancer

Abstract

AbstractAimThis review aimed to describe the potential for therapeutic targeting of the JAK/STAT signaling pathway by repurposing the clinically‐approved JAK inhibitor ruxolitinib in the patients with epithelial ovarian cancer (OC) setting.MethodsWe reviewed publications that focus on the inhibition of the JAK/STAT pathway in hematological and solid malignancies including OC.ResultsPreclinical studies showed that ruxolitinib effectively reduces OC cell viability and metastasis and enhances the anti‐tumor activity of chemotherapy drugs. There are a number of recent clinical trials exploring the role of JAK/STAT inhibition in solid cancers including OC. Early results have not adequately supported efficacy in solid tumors. However, there are preclinical data and clinical studies supporting the use of ruxolitinib in combination with both chemotherapy and other targeted drugs in OC setting.ConclusionInflammatory conditions and persistent activation of the JAK/STAT pathway are associated with tumourigenesis and chemoresistance, and therapeutic blockade of this pathway shows promising results. For women with OC, clinical investigation exploring the role of ruxolitinib in combination with chemotherapy agents or other targeted therapeutics is warranted.
