Summary of Clinical Use Click here for help
Inavolisib (GDC-0077) is being evaluated in a Phase 1 clinical trial (NCT03006172), as a single agent in locally advanced/metastatic PIK3CA-mutant solid tumours, or in combination with CDK4 inhibitor (palbociclib) + aromatase inhibitor (letrozole) + ER antagonist (fulvestrant) in locally advanced/metastatic PIK3CA-mutant ER+ breast cancer.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
GDC-0077 binds to and inhibits PI3K family kinases, including activating mutations in the catalytic alpha isoform PIK3CA (PI3Kα). PIK3CA is frequently mutated in a variety of cancer cell types and this underlies the dysregulation of the PI3K pathway that plays a key role in cancer cell growth and invasion. Pharmacological inactivation of the PI3K pathway inhibits growth and survival of PI3K-overexpressing tumour cells
