"Health Canada’s acceptance of our NDS represents another important regulatory milestone in our commitment to increasing access to NERLYNX around the world to reduce disease recurrence following trastuzumab therapy in patients with early stage HER2-positive breast cancer," said Alan H. Auerbach, Chief Executive Officer and President of Puma. "We look forward to working with Health Canada during their review of our submission."
Neratinib, an oral irreversible pan-HER kinase inhibitor, was approved by the 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. The drug also received a recommendation for marketing authorization from the Committee for Medicinal Products for Human Use (CHMP) in June 2018 and is being reviewed by the European Commission, which has the authority to approve medicines for the European Union.
About HER2-Positive Breast Cancer
Approximately 20% to 25% 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.
