NCT ID NCT03571633
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding pegfilgrastim (a drug that increases white blood cells) to standard chemotherapy and trastuzumab can help the immune system better attack HER2-positive breast cancer before surgery. About 90 women with early-stage, operable breast cancer will take part. The main goal is to see if more tumors completely disappear after treatment.
