Atezolizumab Indication Withdrawn from Triple-Negative Breast Cancer Treatment

In consultation with the FDA, the accelerated approval of atezolizumab (Tecentriq®, Genentech) in combination with nab-paclitaxel has been voluntarily withdrawn from the treatment of patients with programmed death ligand 1 (PD-L1)–positive unresectable locally advanced or metastatic triple-negative breast cancer (TNBC). "Triple-negative breast cancer is a heterogenous disease entity with a high unmet medical need," wrote David Miles, MD, Lead Clinician for Breast Cancer at Mount Vernon Cancer Ce...

New Pembrolizumab Indications Approved for Triple-Negative Breast Cancer

The FDA has granted approval to pembrolizumab (Keytruda®, Merck) for patients with high-risk early-stage triple-negative breast cancer (TNBC) as neoadjuvant treatment in combination with chemotherapy and as single-agent adjuvant treatment following surgery. In addition, the FDA has confirmed the November 2020 accelerated approval of pembrolizumab in combination with chemotherapy for patients with locally recurrent unresectable or metastatic TNBC with a programmed death ligand 1 (PD-L1) combined ...

Sacituzumab Govitecan for Triple-Negative Breast Cancer: Aditya Bardia, MD

Recently, the FDA granted regular approval to sacituzumab govitecan (Trodelvy®, Immunomedics, Inc.) for patients with unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) who have previously been treated with two or more systemic therapies, at least one of them for metastatic disease. The FDA had previously granted accelerated approval to sacituzumab govitecan based on the results of the phase 1/2 IMMU-132-01 study (NCT01631552); the phase 3 ASCENT study (NCT02574455)...

Pembrolizumab FDA Approved for Triple-Negative Breast Cancer

The FDA recently approved pembrolizumab (Keytruda®, Merck & Co) with chemotherapy for patients with locally recurrent unresectable or metastatic triple-negative breast cancer (TNBC) for those whose tumors express PD-L1 (CPS ≥10) as determined by an FDA approved test. In addition, the FDA approved the companion diagnostic, PD-L1 IHC 22C3 pharmDx (Dako North America, Inc.), to select patients with TNBC for pembrolizumab. Efficacy was shown in KEYNOTE-355 (NCT02819518), a multicenter, double-bl...

Does Adjuvant Chemotherapy Benefit Small, Node-Negative TNBC?

Researchers set out to investigate the association between adjuvant chemotherapy and outcomes in patients with small, node-negative, triple-negative breast cancer (TNBC) and found that whereas adjuvant chemotherapy was associated with increased overall survival (OS) in older patients with pT1b tumors, younger patients with pT1a tumors experienced higher rates of mortality. For this observational study, results of which are published in JAMA Oncology, 16,180 patients from the National Cancer Data...

Metronomic Capecitabine Maintenance for TNBC: Zhongyu Yuan, MD

Metronomic capecitabine maintenance therapy has been shown to be more effective compared with observation for patients with triple-negative breast cancer (TNBC), according to a study led by Zhongyu Yuan, MD. Results of the study have been presented at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program. In this interview with i3 Health, Dr. Yuan shares insights on treating TNBC and future directions in the TNBC treatment landscape. What are the most challenging aspec...

TNBC: Metronomic Capecitabine Maintenance Improves Outcomes

Metronomic capecitabine maintenance after standard treatment has been shown to be a successful therapy for patients with triple-negative breast cancer (TNBC) in a recent study. Results of this study will be reported on later this week in the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program. Relapse and unfavorable outcomes are still issues among patients with TNBC. According to lead study author XI Wang, MD of the Department of Breast Oncology at Sun Yat-Sen Universit...

FDA Grants Approval to Sacituzumab Govitecan-Hziy for TNBC

Accelerated approval was granted to sacituzumab govitecan-hziy (Trodelvy™, Immunomedics, Inc), a Trop-2-directed antibody and topoisomerase inhibitor drug conjugate, for patients with metastatic triple-negative breast cancer (TNBC) who have received at least two prior therapies. Sacituzumab govitecan-hziy works by targeting the Trop-2 receptor, mitigating cancer growth and spread. In addition, this drug is linked to topoisomerase inhibitor, which is a chemical compound toxic to cancer cells. "Me...

Disparities Among Patients With Triple-Negative Breast Cancer

Historically, triple-negative breast cancer (TNBC), a disease that tests negative for estrogen, progesterone, and human epidermal growth factor receptors, is more aggressive and carries a worse prognosis than most other types of breast cancer. Researchers conducted a study to understand risk factors that cause disparities in diagnosis in order to develop preventive measures for TNBC and found that women of color and younger women are most at risk of developing TNBC. For this study, published in ...
