For over 50 years, scientists have been on a quest to identify which malignant mutations within the tumor allow rogue cells to break away from the primary tumor and travel through the bloodstream and lymphatic system to metastasize throughout the body. Now, new research suggests an alternative mechanism has been overlooked—elusive mutations driving metastasis may not be developing within the twisted DNA of tumors themselves, but within the patient’s regular, inherited DNA.
The DESTINY-Breast09 phase III trial of AstraZeneca and Daiichi Sankyo’s Enhertu is the first trial in more than a decade to demonstrate superior efficacy across a broad HER2-positive metastatic patient population versus current first-line standard of care.
