plasmaMATCH Trial Shows Neratinib Activity in ERBB2 (HER2) Mutant Metastatic Breast Cancer

Puma Biotechnology, Inc. (Nasdaq: PBYI), a biopharmaceutical company, announced that its collaborators at The Institute of Cancer Research, London, presented results from the cohort of patients in the plasmaMATCH trial treated with Puma's drug neratinib at the 2019 San Antonio Breast Cancer Symposium (SABCS) in San Antonio, Texas. The oral presentation entitled, “Results from the plasmaMATCH trial: A multiple parallel cohort, multi-centre clinical trial of circulating tumour DNA testing to direct targeted therapies in patients with advanced breast cancer (CRUK/15/010),” and the poster presentation entitled, “Results from plasmaMATCH trial treatment Cohort B: A phase II trial of neratinib plus fulvestrant in ER positive breast cancer or neratinib alone in ER negative breast cancer in patients with a ERBB2 (HER2) mutation identified via ctDNA screening (CRUK/15/010)” were presented by Professor Nicholas Turner, M.D., Ph.D., Professor of Molecular Oncology at The Institute of Cancer Research (ICR) and Consultant Medical Oncologist at The Royal Marsden NHS Foundation Trust, who is the principal investigator of the plasmaMATCH trial, and Andrew M. Wardley, M.D., consultant medical oncologist at The Christie NHS Foundation Trust in Manchester, England and Medical Director of the National Institute for Health Research (NIHR) Manchester Clinical Research Facility at The Christie, respectively.

The plasma-based Molecular profiling of Advanced breast cancer to inform Therapeutic Choices (plasmaMATCH) trial is a phase IIa, multiple parallel cohort, open-label, multicentre trial in patients with advanced breast cancer, which aims to assess whether analyzing a blood sample for circulating tumor DNA (ctDNA) could provide an alternative to biopsies for identifying the genetic mutations present in advanced breast cancer and whether subgroups of patients with advanced breast cancer, identified through ctDNA screening, may benefit from a treatment targeting their type of cancer.
