Officials from the FDA have approved a supplemental New Drug Application (sNDA) for neratinib (NERLYNX, Puma Biotechnology) in combination with capecitabine for the treatment of adult patients with advanced or metastatic HER2-positive breast cancer that have received 2 or more prior anti-HER2-based regimens in the metastatic setting.

HER2 is a membrane-bound tyrosine kinase that when amplified contributes significantly to a tumor’s ability to proliferate and survive.

In the pivotal phase 3 KEYNOTE-355 study, pembrolizumab (Keytruda, Merck) combined with chemotherapy met one of its dual primary endpoints of progression-free survival (PFS) as a first-line treatment for patients with metastatic triple-negative breast cancer (TNBC) whose tumors expressed programmed death-ligand 1 (PD-L1).
 

A combination therapy may counter the resistance to human epidermal growth factor receptor 2 inhibitor neratinib in patients with breast, ovarian, lung, or other cancers. 

The study was the first to examine proton pump inhibitors use in breast cancer survivors.

Margetuximab plus chemotherapy showed positive results in a second pre-specified interim overall survival analysis for the phase 3 SOPHIA study.

A study suggests that even brief art-making interventions can be beneficial for stressed caregivers of patients with cancer.

By entering clinical and disease characteristics into a learning algorithm, researchers were able to create an efficacy prediction for CDK inhibitors.

Abemaciclib is a potent oral cyclin-dependent kinase 4/6 inhibitor that has previously demonstrated statistically significant improvement in PFS and ORR in combination with endocrine therapy.
