HER2 and HER3 Alterations as Therapeutic Targets of Increasing Significance in Solid Tumors
@Point of Care™ Morris Tpke, Suite ; Short Hills, NJ ; May 17, · Gastric cancer is a disease with high heterogeneity, and this heterogeneity may result in an uneven distribution of subclones with varied genetic properties at disease locations (spatial heterogeneity) or temporal changes in subclonal composition (temporal heterogeneity). We present the case of a year-old woman with metastatic gastric cancer who presented for . Jun 06, · In patients with HER3-high, HER2-positive metastatic breast cancer, the objective response rate was %. All responses were partial. The median duration of response was months, with a median progression-free survival of 11 .
The disclosure provides monoclonal bispecific antibodies targeting HER2 and HER3. The disclosure also provides monospecific tetravalent HER3 antigen binding. HER2 is overexpressed in % of breast cancer patients and most of them benefit from anti-HER2 targeted therapy. · HER2 dimerizes with HER3 to activate PI3K /. Jun 04, · Patritumab deruxtecan (HER3-DXd) produced encouraging responses in patients with HER3-expressing metastatic breast cancer (MBC) or metastatic triple negative breast cancer (TNBC), according to. Dec 20, · The HER2 receptor extracellular domain has no identifiable ligand, unlike the other EGF family receptors. It is present in an active conformation and can undergo ligand-independent dimerization with other EGF receptors [6, 10, 11]. The most active and tumor promoting combination is thought to be the HER2/HER3 dimer [12–15]. The mechanism of. HER3 is activated by ligand (heregulin) binding but it lacks TK activity, and, like HER2, must partner with another family member to be activated. Nevertheless, it has multiple docking sites for PI3K and when heterodimerized with HER2 is the most potent stimulator of the PI3K/AKT anti-apoptosis pathway (8, 12, 15, 16).
