Abstract
Purpose of review: Neuregulin 1 (NRG1) fusions are rare but actionable oncogenic drivers that occur in a variety of tumor types, including non-small cell lung cancer (NSCLC). These fusions lead to pathophysiologic activation of HER signaling pathways, promoting tumor growth, invasion, and metastasis. Current evidence suggests that NRG1 fusion-positive NSCLC does not respond well to conventional treatments such as immunotherapy and chemotherapy. This review focuses on the biology and detection of NRG1 fusions and the evolving therapeutic landscape of NSCLC harboring NRG1 fusions.
Recent findings: Zenocutuzumab, a bispecific antibody targeting HER2 and HER3, is the first FDA approved treatment for previously treated NRG1 fusion-positive NSCLC and pancreatic cancer. Additional NRG1 fusion directed strategies are in development. NRG1 fusions are rare molecular drivers of NSCLC that can be effectively treated with targeted therapies. Here, we summarize the biology and detection of NRG1 fusions, the currently approved bispecific antibody used to treat NRG1 fusion-positive NSCLC, and new agents under investigation.
期刊介绍:
This journal aims to review the most important, recently published clinical findings in the field of oncology. By providing clear, insightful, balanced contributions by international experts, the journal intends to serve all those involved in the care of those affected by cancer.
We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas, such as cancer prevention, leukemia, melanoma, neuro-oncology, and palliative medicine. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An international Editorial Board reviews the annual table of contents, suggests articles of special interest to their country/region, and ensures that topics are current and include emerging research. Commentaries from well-known figures in the field are also provided.
