CD47 Expression Serves as Predictive Biomarker for HER2+ Breast Cancer
By: Sabrina Serani From: targetedonc.com Key Takeaways CD47 expression levels may predict evorpacept efficacy in HER2-positive metastatic breast cancer, especially in heavily pretreated patients. Evorpacept combined with zanidatamab shows promising results, with a 56% objective response rate and 7.4 months median progression-free survival. The CD47-SIRPα pathway blockade by evorpacept enhances macrophage-mediated phagocytosis, potentially amplifying HER2-targeted therapy effects. Future research will …
