A supplemental New Drug Application for olaparib (Lynparza) has been granted a priority review by the FDA for the&nbsp;treatment of patients with germline <em>BRCA</em>-positive, HER2-negative metastatic breast cancer who have previously received chemotherapy in the neoadjuvant, adjuvant, or metastatic settings,&nbsp;AstraZeneca and Merck, the co-developers of the PARP inhibitor, recently announced.

Ruth O&rsquo;Regan, MD, division head of Hematology and Oncology in the Department of Medicine at the University of Wisconsin School of Medicine and Public Health, discusses treating premenopausal women with breast cancer.

Based on data from the phase III MONARCH 3 trial, a new drug application for abemaciclib (Verzenio) has been granted a priority review by the FDA for&nbsp;use in combination with an aromatase inhibitor for the frontline treatment of women with hormone receptor-positive, HER2-negative advanced or metastatic breast cancer.

Frankie Ann Holmes, MD, Texas Oncology, discusses challenges with neoadjuvant endocrine therapy in breast cancer.

Neoadjuvant Therapy for HER2+ Early Breast Cancer

A look back at all the FDA news that occurred in the month of September.

A supplemental biologics license application for pertuzumab (Perjeta) for use in combination with trastuzumab (Herceptin) and chemotherapy for the adjuvant treatment of patients with HER2-positive early breast cancer&nbsp;has been granted a priority review by the FDA.&nbsp;

Abemaciclib (Verzenio) has been approved by the FDA for use as a monotherapy and in a combination regimen for patients with HR-positive/HER2-negative breast cancer. As a monotherapy, the CDK4/6 inhibitor has been approved for patients with&nbsp;metastatic disease who have previously received endocrine therapy and chemotherapy, and as a combination, abemaciclib has been approved for use with fulvestrant for women with advanced&nbsp;breast cancer with disease progression following endocrine therapy.

Eleftherios (Terry) P. Mamounas, MD, discusses&nbsp;whether 10 years is superior to the widely practiced 5 years of adjuvant hormone therapy in patients with breast cancer.

Investigators recently evaluated the genetic profiles of 160 breast and ovarian cancers associated with germline mutations in <em>BRCA1 </em>and <em>BRCA2 </em>and<em>&nbsp;</em>determined that there is a relationship between the genetics of <em>BRCA</em>1/2 mutations and the risk of resistance to platinum-based chemotherapy.

Younger women with breast cancer, which make up of around 20% of patients, present with unique disease characteristics that warrant careful consideration of potentials treatments, particularly given the potential for long-term side effects.

Hyman B. Muss, MD, UNC Lineberger Comprehensive Cancer Center, UNC School of Medicine, discusses adjuvant therapy for elderly patients with HER2-positive or triple negative breast cancer (TNBC).
