The development of additional molecularly targeted therapies and the search for enhanced immunotherapy regimens are expected to permeate the oncology landscape across a broad range of malignancies as 2021 unfolds.

Sara A. Hurvitz, MD, discusses the expanding HER2-positive metastatic breast cancer treatment arsenal.

Joyce A. O'Shaughnessy, MD, discusses the rationale for the monarchE trial in breast cancer.

Adam M. Brufsky, MD, PhD, discusses the updated findings from the ExteNET trial, the role of TKIs in treating patients with brain metastases, and unanswered questions that future research efforts should aim to address.

January 5th, 2021 -The FDA has granted a fast track designation to the investigational antibody-drug conjugate ARX788 for use as a monotherapy in the treatment of patients with advanced or metastatic HER2-positive breast cancer who have previously received 1 or more HER2-targeted regimens in the metastatic setting.

January 5, 2021 – The FDA has granted permission for a phase 1 study evaluating ON 123300, a first-in-class multikinase CDK4/6 inhibitor to proceed under the agent’s investigational new drug application.

Clinical risk continues to guide treatment decisions in early-stage HER2-positive breast cancer. The presence of brain metastases has become a driving force for treatment selection in the metastatic setting.

Joyce A. O’Shaughnessy, MD, highlights some of the most exciting updates in triple-negative breast cancer that emerged in 2020.

Neelima Vidula, MD, discusses the current and future utility of PARP inhibitors in triple-negative breast cancer, the promise of sacituzumab govitecan, and the need for germline genetic testing.

Phuong L. Mai, MD, discusses the situations in which genetic testing should be considered and the importance of bridging awareness and access within oncology.

Debra Patt, MD, highlights recent advancements and novel approaches in triple-negative breast cancer.
