HER2 Breast Cancer

In patients with HER2-positive breast cancer, an investigational liquid biopsy was more favorable compared with needle biopsies, a study shows.

The addition of tucatinib to standard of care maintenance in the first-line setting for patients with HER2-positive metastatic breast cancer will be examined in the ongoing phase 3 HER2CLIMB-05 trial.

At the 2022 ASCO Annual meeting, trastuzumab dreuxtecan was found to be a superior standard of care therapy for patients with hER2-low, hormone-positive metastatic breast cancer.

A safety follow-up analysis of the randomized phase 3 DESTINY-Breast03 study reinforced the risk-benefit profile of trastuzumab deruxtecan compared with trastuzumab emtansine in patients with HER2-positive unresectable or metastatic breast cancer

Metastatic triple-negative breast cancer appears to derive clinical benefit from sacituzumab govitecan-hziy overtime, regardless of patients’ HER2 expression, according to a post hoc analysis of the phase 3 ASCENT trial.

Survival rates for patients with different subtypes of early breast cancer who had a pathological complete response after de-escalated 12-week trastuzumab plus pertuzumab with or without weekly paclitaxel are promising.

Breakthrough therapy designation has been granted to trastuzumab deruxtecan by the FDA for patients with unresectable or metastatic HER2-low breast cancer.

Pyrotinib combined with apecitabine demonstrated promising activity in patients with HER2-positive breast cancer that have brain metastases, according to findings from the prospective phase 2 PERMEATE study.

Significant survival improvement has been shown with trastuzumab deruxtecan in patients with HER2-low breast cancer treated in the DESTINY-Breast04 clinical trial.

In an interview with Targeted Oncology, Ron Bose, MD, MPH, discussed HER2 drug resistance, its impact on treatment, and how new research may help in the future.

The FDA has accepted a supplement biologics license application for fam-trastuzumab deruxtecan-nxki and granted it priority review for the treatment of adult patients with unresectable or HER2-positive metastatic breast cancer who have received a prior anti-HER2- based regimen.

HER2 mutations are a major clinical biomarker in breast cancer. However, overcoming drug resistance remains a key clinical obstacle.

Alexandra S. Zimmer, MD, discusses the safety of the combination of the T-DM1 ado-trastuzumab emtansine and temozolomide, for the prevention of further brain metastases in patients with HER2-positive breast cancer with brain metastases.

Based on updated findings from the phase 2 SUMMIT trial, a neratinib triplet and neratinib doublet can induce responses in patients with HER2-positive breast cancer.

Alexandra Higgins, MD, discusses when to use ado-trastuzumab emtansine in patients with HER2-positive breast cancer, and how to address particular adverse events that patients may develop while on treatment.

Fam-trastuzumab deruxtecan-nxki led to prolonged progression-free survival and higher responses compared with ado-trastuzumab emtansine as second-line therapy in patients with HER2-positive metastatic breast cancer.

Updated data from the PHOEBE trial show that pyrotinib plus capecitabine improved overall survival in patients with HER2-positive breast cancer compared with lapatinib plus capecitabine.

Adding zanidatamab to chemotherapy may result in positive efficacy and safety outcomes in patients with HER2-positive breast cancer.

A non-chemotherapy–based targeted regimen comprised of tucatinib, palbociclib, and letrozole was found to prolong central nervous system (CNS) progression-free survival (PFS) in patients with hormone receptor–positive, HER2-positive breast cancer.

Alexandra S. Zimmer, MD, discusses treatment options for patients with HER2-positive breast cancer who have developed brain metastasis.

In an interview with Targeted Oncology, lead author Xichun Hu, MD, PhD, discussed A166 and its impact on HER2-positive breast cancer.

Guiseppe Curigliano, MD, discusses the rationale behind a subgroup HER2CLIMB study, which evaluated the efficacy and safety of tucatinib in combination with trastuzumab and capecitabine in pretreated HER2-positive breast cancer patients with and without brain metastases compared with placebo.

Frederick Howard, MD, a medical oncology fellow in the Department of Medicine at the University of Chicago, discussed the clinical benefits of the SimBioSys TumorScope model for the treatment of early breast cancer in an interview with Targeted Oncology.

Zanidatamab in combination with evorpacept has been dosed for the first time in a patient with HER2-low breast cancer.
