谁有必威体育网站首页 - Puma Biotechnology, Inc. (Nasdaq: PBYI) announced that the European Commission (EC), has granted marketing authorisation for NERLYNX® (neratinib) for the extended adjuvant treatment of adult patients with early stage hormone receptor positive HER2-overexpressed/amplified breast cancer and who are less than one year from the completion of prior adjuvant trastuzumab based therapy.
- Neratinib becomes the first anti-HER2 treatment to be EC-approved as extended adjuvant therapy for early stage hormone receptor positive HER2-positive breast cancer following adjuvant trastuzumab-based therapy.
- Treatment with neratinib in the approved European indication resulted in a 51% reduction in the risk of invasive disease recurrence or death versus placebo after patients completed one year of therapy following a trastuzumab-based regimen.
- Neratinib addresses an unmet medical need, as up to 25% of HER2-positive early stage breast cancer patients treated with trastuzumab-based adjuvant treatment experience a recurrence.
EC approval was based on the Phase III ExteNET trial, a multicenter, randomized, double-blind, placebo-controlled trial of neratinib following adjuvant trastuzumab treatment. Patients (n=2,840) with early stage HER2-positive breast cancer and within two years of completing adjuvant trastuzumab were randomized to receive either neratinib (n=1420) or placebo (n=1420) for one year.
The results of the ExteNET trial demonstrated that after two years of follow-up, for patients with hormone receptor positive, HER2-positive early stage breast cancer patients who were treated within one year after the completion of trastuzumab based adjuvant therapy, invasive disease-free survival (iDFS) was 95.3% in the patients treated with neratinib compared with 90.8% in those receiving placebo (hazard ratio = 0.49; 95% CI: (0.30, 0.78); p=0.002)
The most common adverse reactions (>5%) were diarrhea, nausea, abdominal pain, fatigue, vomiting, rash, stomatitis, decreased appetite, muscle spasms, dyspepsia, AST or ALT increase, nail disorder, dry skin, abdominal distention, weight loss, and urinary tract infection. The most common adverse reaction leading to discontinuation was diarrhea, which was observed in 16.8% of neratinib-treated patients. Hepatotoxicity or increases in liver transaminases led to drug discontinuation in 1.7% of neratinib-treated patients.
“Reducing the risk of disease recurrence remains a need for patients, despite advances in the treatment of early stage HER2-positive breast cancer,” said Puma Biotechnology CEO and President Alan H. Auerbach. “We are pleased to bring this new medicine to patients in Europe and would like to express our appreciation to the patients, caregivers and physicians who contributed to the neratinib clinical development program and, more specifically, the ExteNET trial. We are committed to continuing to expand NERLYNX accessibility to patients worldwide. We expect NERLYNX to be commercially available in Europe in 2019, beginning with our launch in Germany during the first half of 2019 and followed by additional countries throughout Europe in the second half of 2019.”
The approval of NERLYNX by the European Commission follows the positive opinion issued by the Committee for Medicinal Products for Human Use of the European Medicines Agency in June 2018.
Neratinib was approved by the U.S. Food and Drug Administration (FDA) in July 2017 for the extended adjuvant treatment of adult patients with early stage HER2-positive breast cancer following adjuvant trastuzumab-based therapy, and is marketed in the United States as NERLYNX® (neratinib) tablets.
Approximately 20 to 25 percent of breast cancer tumors over-express the HER2 protein. HER2-positive breast cancer is often more aggressive than other types of breast cancer, increasing the risk of disease progression and death. Although research has shown that trastuzumab can reduce the risk of early stage HER2-positive breast cancer returning after surgery, up to 25% of patients treated with trastuzumab experience recurrence.
