[{"type":"text","content":"\nData published online in Clinical Breast Cancer\n\n LOS ANGELES--(BUSINESS WIRE)--\nPuma Biotechnology, Inc. (NASDAQ: PBYI), a biopharmaceutical company, announced that efficacy results of neratinib in HER2-positive, hormone receptor-positive (HR+), early stage breast cancer (eBC) from the Phase III ExteNET trial were published in Clinical Breast Cancer. The manuscript appears in the October 5, 2020 online issue accessible at https://www.clinical-breast-cancer.com/article/S1526-8209(20)30258-5/fulltext.\n\nExteNET was a multicenter, randomized, double-blind, Phase III trial of 2,840 HER2-positive eBC patients who received neratinib after neoadjuvant and/or adjuvant therapy with chemotherapy and trastuzumab. Patients were stratified by hormone receptor status and randomly assigned to one year of treatment with either oral neratinib 240 mg/day or placebo. The primary endpoint of the trial was invasive disease-free survival (iDFS) with overall survival as a key secondary endpoint. Within the European Union, neratinib is approved in patients with HR+ breast cancer who initiated treatment within one year of completing an adjuvant trastuzumab containing regimen.\n\nThe manuscript presents data focusing on HR+ patients who initiated treatment within a year of completing an adjuvant trastuzumab containing treatment (HR+ /< 1 yr) and subgroups of clinical interest including patients who did not achieve a pathological complete response (no pCR) after neoadjuvant treatment and therefore were at a high risk of disease recurrence.
