Irbinitinib(CAT: I005570), also known as TP-0903, is an orally administered small molecule inhibitor of the receptor tyrosine kinase AXL. AXL plays a crucial role in the regulation of various cellular processes such as proliferation, migration, invasion, and survival. Overexpression of AXL has been associated with poor prognosis in various types of cancer. Irbinitinib has shown potent anti-tumor activity in preclinical studies and is being investigated in clinical trials for the treatment of solid tumors, including non-small cell lung cancer and triple-negative breast cancer.

Overview of Clinical Research

Irbinitinib is a ERBB 2 receptor antagonist. It has been granted for the orphan drug status in Colorectal cancer and Breast cancer.
