Background:Inavolisib is a highly potent and selective inhibitor of the alpha isoform of the p110 catalytic subunit of the phosphatidylinositol 3-kinase complex(encoded by PIK3CA)that also promotes the degradation of mutated p110α.Inavolisib plus palbociclib-fulvestrant has shown synergistic activity in preclinical models and promising antitumor activity in early-phase trials.
