A phase Ib/II trial of neoadjuvant neratinib added to standard therapy in patients with HER2-positive or HR-positive/HER2-negative inflammatory breast cancer (including stage III and IV disease).

ABSTRACT:

Background

Inflammatory breast cancer (IBC) is rare but aggressive, characterized by the rapid onset of diffuse skin erythema, edema, tenderness, induration, and fast metastasis. Both hormone receptor positive (HR+) and human epidermal receptor 2 positive (HER2+) are associated with inferior response after neoadjuvant systemic therapy (NAST) compared to non-IBC. Despite multimodal treatment approaches, the 3-year overall survival rate for stage III IBC remains low at approximately 74%, around 10% lower than the 83% for non-IBC.

Objectives

To evaluate whether the addition of neratinib, an irreversible pan-ErbB receptor small molecule tyrosine kinase inhibitor, improves the rate of pathological complete response in both HER2+ and HR+/HER2- IBC in neoadjuvant therapy, and to as
