"Breast cancer"

Every year, 40000 women die of breast cancer in the United States alone. When cancers are discovered at an early stage, they can often be cured. Mammography is the best alternative diagnostic method, but this method also has shortcomings. It often results in false positive results, leading to unnecessary surgery.

The US FDA approved the ADC drug gosatumumab (Trodelvy) for the treatment of patients with hormone receptor-positive, HER2-negative breast cancer. In the trial, the drug significantly extended the overall survival of patients and reduced the risk of death by 21%.

St. Marianna's Medical University Hospital is one of the top hospitals in Japan, specializing in breast surgery and other related diseases.

DZD1516 is a reversible, selective HER2-targeting agent with full blood-brain barrier penetration. It has demonstrated good therapeutic response in phase I studies in patients with metastatic HER2-positive breast cancer, including breast cancer patients with central nervous system metastases.

The FDA granted priority review status to Enhertu (DS-8201) for the treatment of patients with HR-positive, low HER2-expressing breast cancer, and Enhertu has enabled these patients to remain disease-free for an average of 10.1 months, with an average overall survival time of nearly two years. A decision on approval is expected to be made in the fourth quarter of this year.
