AstraZeneca has recently completed a significant study titled ‘Multicentre NIS Retrospective Study to Know the Prevalence of HER2- Low, Clinical Characteristics, Treatment Patterns, Associated Outcome in Patient With HER2-negative in Metastatic Breast Cancer Who Progressed on Systemic Anticancer Therapy.’ The study aimed to determine the prevalence and clinical characteristics of HER2-low metastatic breast cancer in patients previously identified as HER2-negative. This research is crucial as it targets emerging markets outside the US and Europe, where data on HER2-low mBC prevalence is scarce.
The study did not involve any new interventions or treatments since it was observational. Instead, it focused on rescoring archived slides to gather data on HER2-low prevalence and associated clinical outcomes in patients with metastatic breast cancer.
This observational study used a cohort model with a retrospective time perspective. It did not involve any allocation or masking, as it was designed to observe and analyze existing data rather than test new treatments. The primary purpose was to gather insights into the prevalence and characteristics of HER2-low breast cancer.
The study began on November 9, 2023, and was completed with the last update submitted on September 17, 2025. These dates are crucial as they mark the timeline of data collection and analysis, providing a framework for understanding the study’s progress and completion.
The completion of this study could have significant implications for AstraZeneca’s stock performance and investor sentiment. By providing new insights into HER2-low breast cancer, AstraZeneca could strengthen its position in the oncology market, potentially impacting its competitive standing and market share. Investors may view this as a positive development, given the potential for new treatment strategies and market expansion.
The study is now completed, with further details available on the ClinicalTrials portal for those interested in more in-depth information.
