Roche’s Blockbuster Vision for Itovebi: A Beacon of Hope in PIK3CA-Mutated Breast Cancer Treatment

Breast cancer remains a significant global health challenge, with numerous subtypes and varying patient responses to treatment. Among these, hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer is the most common, often presenting as locally advanced or metastatic disease. For patients with tumors harboring mutations in the PIK3CA gene, resistance to standard hormone therapy can lead to poorer outcomes.
