Overview

Tivumecirnon is an orally available small molecule antagonist of C-C chemokine receptor type 4 (CCR4). It is designed to block the migration of regulatory T cells (Tregs) specifically into tumors without depleting Tregs throughout the body. By inhibiting CCR4-mediated recruitment of immunosuppressive Tregs to the tumor microenvironment, tivumecirnon aims to abrogate immune suppression and promote effective antitumor immune responses. This mechanism may enhance the efficacy of other cancer therapies such as checkpoint inhibitors and has shown promise in combination with pembrolizumab for various cancers including EBV-positive gastric cancer, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and extranodal NK/T-cell lymphoma[1][2][5][6][7][8][10].
