Roche’s Itovebi Regimen Delivers Significant Survival Benefit in Advanced Breast Cancer
SHERIDAN, WYOMING – June 1, 2025 – Roche has announced compelling final overall survival data from its phase III INAVO120 study, showing that the Itovebi™ (inavolisib)-based regimen reduces the risk of death by more than 30% in patients with PIK3CA-mutated, HR-positive, HER2-negative advanced breast cancer. The findings were presented at the 2025 ASCO Annual Meeting and simultaneously published in the New England Journal of Medicine.
First PI3K Inhibitor to Prolong Survival in This Breast Cancer Subtype
The INAVO120 trial demonstrated that Itovebi, when combined with palbociclib and fulvestrant, achieved a median overall survival (OS) of 34.0 months compared to 27.0 months for the control group receiving palbociclib and fulvestrant alone. This represents a statistically significant and clinically meaningful improvement (HR=0.67; p=0.0190).
