Improving quality of life for patients with HER2-positive breast cancer.


HER2 is an oncogene that plays a role in the development and progression and is a driving force in about 30 percent of breast cancers. Non-metastatic HER2-positive breast cancer, once a deadly disease, is now curable in more than 90 percent of cases, but the treatments can cause severe side effects. Standard adjuvant (post-surgery) treatment for early-stage HER2-positive breast cancer includes multiple lines of chemotherapy plus HER2-directed therapy even though there is not a clear benefit to more chemotherapy. Most patients with non-metastatic, HER2-positive disease have excellent long-term outcomes, so it is important to be able to identify who can be treated just as effectively with less toxic, less intensive therapy. Dr. Winer aims to personlize the amount of chemotherapy while maintaining treatment efficacy, which will improve quality of life and decrease the chance of rare but serious chemotherapy complications.

Progress Thus Far

Dr. Winer’s work is based on earlier studies showing that additional chemotherapies after surgery can have both short-term adverse effects such as nausea, fatigue, and hair loss and long-term effects such as the potential of heart damage or secondary leukemia. Though chemotherapy-associated toxicities are common, they are still useful or necessary for patients with more aggressive cancers who can benefit from them. Over the past year, Dr. Winer completed the DAPHNe clinical trial, which showed the feasibility and promise of this approach.

What’s next

Dr. Winer has now begun accrual to the MARGOT trial, as well as two smaller phase II trials incorporating the novel anti-HER2 antibody drug margetuximab (MARGENZA™) into pre-operative treatment for HER2-positive breast cancer. He will conduct analyses from clinical samples to gain a better understanding of the relationship between anti-HER2 antibody therapy and clinical outcomes after neoadjuvant therapy.
