Description
Inavolisib is a PI3K alpha-selective inhibitor currently in clinical development for metastatic colorectal cancer. This targeted therapy is designed to block the PI3K/AKT/mTOR signaling pathway, which is frequently dysregulated in colorectal tumors harboring PIK3CA mutations. The drug is being evaluated in combination with standard chemotherapy regimens including FOLFOX and FOLFIRI, as well as with bevacizumab for first-line treatment of metastatic disease. Clinical trials are focusing on patients with specific molecular alterations, particularly PIK3CA mutations and certain KRAS mutations.
Mechanism of Action
Inavolisib selectively inhibits the PI3K alpha isoform (PIK3CA), which plays a crucial role in cell survival, proliferation, and metabolism pathways. By blocking PI3K alpha activity, the drug disrupts downstream AKT and mTOR signaling, leading to reduced tumor cell growth and enhanced apoptosis in cancer cells dependent on this pathway.
