Compound class: Synthetic organic
Comment: Inavolisib (GDC-0077) is a potent and selective, orally available PI3K-p110α (PIK3CA) inhibitor, with potential antineoplastic activity. It is example 101 in patent US20170015678 (where it is named (S)-2-((2-((S)-4-(difluoromethyl)- 2-oxooxazolidin-3-yl)-5,6- dihydrobenzo[f]imidazo[1,2- d][1,4]oxazepin-9- yl)amino)propanamide) [1]. GDC-0077 is one of the agents in Genentech's oncology discovery pipeline. A preprint from May 2021 suggests that inavolisib's mechanism of action includes the ability to target oncogenic mutant PI3K-p110α for degradation, in addition to its enzyme inhibitory activity [2].

Summary of Clinical Use Click here for help
Inavolisib (GDC-0077) has advanced to Phase 2/3 clinical evaluation in advanced solid tumours. It is being used to target tumours (principally breast cancers) that harbour PIK3CA mutations that are predictive of a clinical response.
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
