Combination of anti-HER3 antibody MM-121/SAR256212 and cetuximab inhibits tumor growth in preclinical models of head and neck squamous cell carcinoma.
The EGFR monoclonal antibody cetuximab is the only approved targeted agent for treating head and neck squamous cell carcinoma (HNSCC). Yet resistance to cetuximab has hindered its activity in this disease. Intrinsic or compensatory HER3 signaling may contribute to cetuximab resistance. To investigate the therapeutic benefit of combining MM-121/SAR256212, an anti-HER3 monoclonal antibody, with c...
متن کاملDual targeting of HER3 and MEK may overcome HER3-dependent drug-resistance of colon cancers
Although the medical treatment of colorectal cancer has evolved greatly in the last years, a significant portion of early-stage patients develops recurrence after therapies. The current clinical trials are directed to evaluate new drug combinations and treatment schedules. By the use of patient-derived or established colon cancer cell lines, we found that the tyrosine kinase receptor HER3 is in...
متن کاملPersonalized Medicine and Imaging Increased Expression of HER2, HER3, and HER2:HER3 Heterodimers in HPV-Positive HNSCC Using a Novel Proximity-Based Assay: Implications for Targeted Therapies
Purpose: In other cancer types, HPV infection has been reported to coincide with overexpression of HER2 (ERBB2) and HER3 (ERBB3); however, the association between HER2 or HER3 expression and dimer formation in HNSCC has not been reported. Overexpression of HER2 and HER3 may contribute to resistance to EGFR inhibitors, including cetuximab, although the contribution of HPV in modulating cetuximab...

متن کاملPharmacological Targeting of the Pseudokinase Her3
Her3 (also known as ErbB3) belongs to the epidermal growth factor receptor tyrosine kinases and is well credentialed as an anti-cancer target but is thought to be 'undruggable' using ATP-competitive small molecules because it lacks appreciable kinase activity. Here we report what is to our knowledge the first selective Her3 ligand, TX1-85-1, that forms a covalent bond with Cys721 located in the...
