Genentech Announces Positive Phase III Results for Inavolisib Combination in People With Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer With a PIK3CA Mutation
Date: 04 December 2023
Phase III (INAVO120) results shows that inavolisib in combination with palbociclib and fulvestrant significantly improved progression-free survival in the first-line setting PIK3CA mutations, found in approximately 40% of HR-positive breast cancers, are linked to tumor growth, disease progression, and treatment resistance Data will be shared with health authorities and presented at an upcoming medical meeting
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today positive results from the Phase III INAVO120 study of the investigational therapy, inavolisib, in combination with palbociclib (Ibrance®) and fulvestrant as a potential first-line treatment option for people with PIK3CA-mutated, hormone receptor (HR)-positive, HER2-negative, endocrine-resistant, locally advanced or metastatic breast cancer. The study met its primary endpoint of progression-free survival (PFS), demonstrating a statistically significant and clinically meaningful improvement compared to palbociclib and fulvestrant alone. Overall survival data were immature at this time, but a clear positive trend has been observed. Follow-up will continue to the next analysis.
