ASCO study: Use of off-label drugs in breast cancer quite common

“Higher pretreatment HER2 amplicon mRNA signature and HER2 protein expression predicted improved outcomes with T-DXd for [metastatic breast cancer],” Paolo Tarantino, MD, PhD, said.

Findings highlight a need to incorporate diverse populations when developing guideline-concordant breast cancer care to achieve efficacy for all patients.

Data from the phase 3 NATALEE trial confirms ribociclib plus NSAI consistently improves survival outcomes in stage II/III HR+/HER2– early breast cancer patients, regardless of age or menopausal status.

Paolo Tarantino, MD, and Matteo Lambertini, MD, PhD discuss findings related to CDK4/6 inhibitors and antibody drug conjugates presented at SABCS 2024.

Camizestrant and continued CDK4/6 inhibition delayed time to QOL deterioration vs SOC therapy in ER+/HER2– advanced breast cancer.

Patients who received ipatasertib/fulvestrant in the intention-to-treat population achieved a median PFS of 5.32 months compared with 1.94 months in the placebo arm.
