Can Trastuzumab Duration Be Shortened in HER2-Positive Breast Cancer?

Excerpt:

“Adding to a growing list of similar results, the Short-HER study was unable to show noninferiority of 9 weeks of trastuzumab compared with the standard 1 year when given along with chemotherapy in women with HER2-positive breast cancer. Shorter administration does, however, reduce the risk of cardiotoxicity.

” ‘Adjuvant pivotal trials with 1-year trastuzumab have significantly improved the prognosis of HER2-positive early breast cancer,’ wrote study authors led by Pierfranco Conte, MD, of the Istituto Oncologico Veneto in Italy. Several studies have attempted to reduce the duration of trastuzumab, though most have failed to show noninferiority.”

Does Sequential vs Concurrent Treatment Change Outcomes in HER2+ Breast Cancer?

Excerpt:

“Outcomes for patients with HER2-positive breast cancer did not differ when treated with sequential chemotherapy plus trastuzumab compared with a concurrent approach, according to a new phase III trial.

” ‘The effectiveness of trastuzumab with chemotherapy in the neoadjuvant setting is evident; however, the cardiac safety of trastuzumab combined with anthracyclines has been questioned,’ wrote study authors led by Kelly K. Hunt, MD, of the University of Texas MD Anderson Cancer Center in Houston.”

Neratinib/T-DM1 Combo Shows Promise in HER2-Positive Breast Cancer

Excerpt:

“The combination of neratinib (Nerlynx) and T-DM1 (ado-trastuzumab emtansine; Kadcyla) induced an overall response rate of 60% in previously-treated women with HER2-positive metastatic breast cancer, according to results from the phase Ib NSABP FB-10 study presented at the 2018 ASCO Annual Meeting.

“Among 12 of 20 evaluable patients with objective responses, 3 had a complete response and 9 had a partial response. An additional 2 patients had stable disease, and 6 patients had progressive disease.”

Tucatinib Active in Heavily Pretreated HER2+ Breast Cancer

Excerpt:

“Tucatinib used in combination with capecitabine, trastuzumab (Herceptin), or both agents showed promising antitumor activity in heavily pretreated women with HER2-positive breast cancer with or without brain metastases, according to findings published in The Lancet Oncology.

“In phase Ib results from a nonrandomized, open-label study, 83% (5/6) of patients with measurable disease treated with tucatinib/capecitabine had an objective response, as did 40% (6/15) of patients receiving tucatinib/trastuzumab. Sixty-one percent (14/23) of patients treated with the combination of all 3 drugs had an objective response.”

Hurvitz Heralds Next HER2+ Breast Cancer Breakthroughs

Excerpt:

“The 5 FDA-approved HER2-targeted agents have altered the natural course of HER2-positive breast cancer, explained Sara A. Hurvitz, MD, at the 2018 Miami Breast Cancer Conference (MBCC).

” ‘These therapies have altered the way patients can now live with this disease,’ said Hurvitz, noting that the stage is now set for the next wave of treatment breakthroughs.”

Targeting ER, HER2, and RB1 Shows Promise in HER2/ER+ Breast Cancer

Excerpt:

“A combined approach targeting estrogen receptor (ER), HER2, and RB1 yielded promising results in terms of Ki-67 expression in an exploratory study of women with HER2-positive, ER-positive breast cancer.

” ‘HER2-positive, ER-positive tumors have molecular features distinct from those of HER2-positive, ER-negative cancers, suggesting that the two types of tumors should be treated with differently tailored approaches,’ wrote study authors led by Luca Gianni, MD, of San Raffaele Scientific Institute in Milan. Previous work has suggested that a combined approach targeting HER2, ER, and RB1 may improve outcomes.”

Pertuzumab and Other Agents Continue Progress in HER2+ Breast Cancer

Excerpt:

“The adjuvant treatment landscape for patients with HER2-positive breast cancer continues to grow, particularly following the recent FDA approval of pertuzumab (Perjeta) in combination with trastuzumab (Herceptin) and chemotherapy, which was based on findings from the APHINITY trial.

“In the phase III trial, the combination demonstrated a 3-year invasive disease-free survival (DFS) rate of 94.1%, which represented an 18% reduction in the risk of developing invasive disease or death. The benefit was more pronounced among higher-risk patients. The DFS rate for patients with node-positive disease was 92.0% with pertuzumab versus 90.2% with standard therapy.”

Immunotherapy Shows Early Promise for Patients With Trastuzumab-Resistant Breast Cancer

Excerpt:

“A combination of pembrolizumab (Keytruda) and trastuzumab, tested in patients with trastuzumab-resistant advanced HER2-positive breast cancer, was well tolerated and had clinical benefit in patients whose tumors were positive for a biomarker for pembrolizumab, according to data presented from the phase Ib/II PANACEA trial at the 2017 San Antonio Breast Cancer Symposium, held Dec. 5–9.

“ ‘We wanted to investigate if immunotherapy approaches can work in patients with advanced HER2-positive breast cancer that is resistant to trastuzumab,’ said Sherene Loi, MD, PhD, associate professor at Peter MacCallum Cancer Centre in Melbourne, Australia, working with the International Breast Cancer Study Group (IBCSG).”

Traditional vs Targeted Chemotherapy in HER2-Positive Breast Cancer

Excerpt:

“Traditional neoadjuvant chemotherapy along with dual HER2-targeted blockade yielded significantly better response rates than a novel approach using HER2-targeted chemotherapy plus HER2-targeted blockade, according to a randomized phase III trial.

” ‘Despite the improvements in outcomes associated with HER2-directed therapy, approximately a quarter of patients who receive treatment for their early breast cancer remain at risk of relapse after 8–10 years, and around 15% will die within a decade,’ wrote study authors led by Sara A. Hurvitz, MD, of the David Geffen School of Medicine at the University of California, Los Angeles. A need for new strategies in this setting led the investigators to test a neoadjuvant regimen of the antibody–drug conjugate trastuzumab emtansine along with pertuzumab in comparison with traditional systemic chemotherapy along with trastuzumab plus pertuzumab.”
