HER2 Breast Cancer

Experts in breast oncology discuss the evolving landscape in early stage and metastatic HER2-positive breast cancer.

A review of key relevant data on HER2-positive breast cancer from the 2020 SABCS Virtual Symposium.

During a Targeted Oncology Case-Based Peer Perspectives Roundtable event, Ruta D. Rao, MD, discussed the case of 42-year-old woman with HER2-positive breast cancer.

William J. Gradishar, MD, discusses the current standard of care for patients with HER2-positive breast cancer, as well as some other promising therapies in this space.

The FDA granted a Fast Track designation to ARX788 as a single agent for the treatment of patients with advanced or metastatic HER2-positive breast cancer who received at least 1 prior anti-HER2 regimen in the metastatic setting.

The FDA granted approval to the Fc-engineered, monoclonal antibody margetuximab in combination with chemotherapy, as treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease.

Neratinib in combination with capecitabine induced a 34% reduction in the risk of disease progression or death as treatment of patients with HER2-positive breast cancer who had central nervous system metastases at baseline compared with lapatinib and capecitabine.

Patients with HER2-positive metastatic breast cancer and brain metastases treated with the combination of tucatinib, trastuzumab, and capecitabine had significantly lengthened the time to deterioration of health-related quality of life, according to the results of an analysis of the HER2CLIMB clinical trial presented during the 2020 San Antonio Breast Cancer Symposium.

William J. Gradishar, MD, discussed the effect tucatinib had on central nervous system metastases in patients with HER2-positive breast cancer.

To identify which patients with HER2-positive breast cancer are most likely to respond to fam-trastuzumab deruxtecan-nxki, investigators used a novel HER2 quantitative continuous score to provide a better objective and quantitative assessment of HER2 expression, data presented during the 2020 San Antonio Beast Cancer Symposium show.

Patients with HER2-positive metastatic breast cancer treated with fam-trastuzumab deruxtecan-nxki had continued to experience extended durable responses and overall survival rates, along with tolerable toxicity in the phase 2 DESTINY-Breast01 study for which data were presented during the 2020 San Antonio Breast Cancer Symposium.

Despite having similar disease characteristics and treatment patterns, elderly patients with HER2-positive advanced breast cancer aged ≥ 70 years experienced shorter chemotherapy durations than patients under the age of 70, as well as, poorer overall survival, and increased rates of adverse events in a real-world study.

The most interesting developments and approvals in breast cancer treatment in the last year and expectations regarding data that will be presented on at the upcoming 2020 San Antonio Breast Cancer Symposium.

Hope Rugo, MD, discusses her key takeaways in the field of HER2-positive breast cancer.

Although the dual HER2 blockade combination is now considered a standard regimen for the treatment of patients with HER2-positive early-stage breast cancer, there are limited efficacy data regarding the use of the regimen in Asian populations.

A phase 3 study was initiated for a head-to-head comparison of trastuzumab deruxtecan versus T-DM1 as adjuvant treatment of a subset of patients with HER2-positive early breast cancer.

In an interview with Targeted Oncology, William J. Gradishar, MD, discussed the current treatment options for patients with HER2-positive breast cancer, including the recently approved therapies from the FDA. He also shared his insights on treating patients with brain metastases, in particular.

During a recent tweet chat, Sara M. Tolaney, MD, MPH, joined Targeted Oncology for the discussion of a 39-year-old woman with relapsed/refractory HR-negative/HER2-positive metastatic breast cancer.

Until recently, few options existed for patients with HER2-positive breast cancer who progressed on earlier lines of therapy. Recent approvals of 3 drug combinations offer new tools that may prolong life and control brain metastases across lines of therapy.

A number of targeted agents have been approved in the setting of metastatic breast cancer, which has allowed for more personalized treatment approaches and underscores the importance of genomic testing.
