Phase III HER2CLIMB Trial Yields Positive Data in Patients With HER2-Positive Metastatic Breast Cancer and Brain Metastasis
The investigational oral agent tucatinib added to trastuzumab/capecitabine reduced the risk of death by one-third and reduced the risk of disease progression or death by one-half in patients with heavily pretreated metastatic HER2-positive breast cancer, including those with untreated or previously ...
Chemotherapy, Trastuzumab, and Pertuzumab in Early HER2-Positive, Node-Positive Breast Cancer: Six-Year Follow-up of APHINITY Trial
Martine J. Piccart, MD, PhD, FASCO, reported that at 6-year follow-up of the APHINITY trial there was a modest, but not statistically significant, overall survival benefit for the addition of pertuzumab to chemotherapy plus trastuzumab vs chemotherapy/trastuzumab as adjuvant therapy in patients...
Phase II DESTINY-Breast01: T-DXd Effective in Pretreated, Metastatic HER2-Positive Breast Cancer
In heavily pretreated patients with HER2-positive metastatic breast cancer [fam-]trastuzumab deruxtecan-nxki (T-DXd), a novel antibody-drug conjugate, achieved high response rates and durable responses, according to results of the phase II DESTINY-Breast01 trial presented at the 2019 San Antonio...
Adjuvant Ado-Trastuzumab Emtansine vs Paclitaxel Plus Trastuzumab in Early HER2-Positive Breast Cancer
Results of the randomized, phase II ATEMPT trial showed that the antibody-drug conjugate ado-trastuzumab emtansine (T-DM1) failed to demonstrate improved safety when compared with paclitaxel plus trastuzumab as adjuvant therapy in patients with stage 1 HER2-positive breast cancer. These results of...
Adding Capecitabine to Systemic Therapies Improves Outcomes in Triple-Negative Breast Cancer
Capecitabine improves disease-free and overall survival for patients with triple-negative breast cancer, but only when it is added to other systemic therapies, not when it is used as a substitute, according to a large meta-analysis of the effects of capecitabine in early breast cancer, The results...
Phase III KEYNOTE-522: Pembrolizumab Benefits Outcome in Neoadjuvant, Adjuvant Settings in Triple-Negative Breast Cancer
In patients with triple-negative breast cancer, the addition of pembrolizumab to neoadjuvant and adjuvant chemotherapy achieves higher rates of pathologic complete response compared with placebo, according to results of the phase III KEYNOTE-522 trial presented at the 2019 San Antonio Breast Cancer ...
Phase III SOPHIA Trial Evaluates Margetuximab/Chemotherapy vs Trastuzumab/Chemotherapy for HER2-Positive Breast Cancer
The second interim analysis of the phase III SOPHIA trial demonstrated a significant though modest improvement in progression-free survival, response rate, and clinical benefit with the addition of margetuximab to chemotherapy vs trastuzumab plus chemotherapy in patients with HER2-positive...
Small Study Explores Impact of Novel Regimen on Pembrolizumab for Triple-Negative Breast Cancer
In the phase II KEYNOTE-890 trial, patients with inoperable advanced triple-negative breast cancer who received one intratumoral tavokinogene telseplasmid injection followed by electroporation and pembrolizumab, several patients with skin or subcutaneous tumors saw metastatic lesions disappear,...
Investigators in Brazil Explore Availability, Cost, and Use of Biosimilar Trastuzumab in Patients With HER2-Positive Breast Cancer
Investigators in Brazil are seeking to explore the efficacy and safety of adjuvant biosimilar trastuzumab in a real-world study of patients with early HER2-positive breast cancer. In 2019, biosimilar trastuzumab became the first biosimilar approved in Brazil for the treatment of patients with...
NSABP B-42 Trial 10-Year Update: Impact of Extended Letrozole on Disease-Free Survival
“In the 10-year analysis of the NSABP B-42 trial, the effect of extended treatment with 5 years of letrozole on disease-free survival persisted and reached statistical significance. There was no significant improvement in overall survival with letrozole, but letrozole continued to provide a...
