Differences in the immune reactions between smokers and nonsmokers may explain why only 20% of patients with lung cancer respond to immunotherapy treatment. Understanding these differences in the evolution of lung cancer between smokers and nonsmokers could be the key to unlocking new treatments.
At the recently concluded AACR meeting, Biocytogen Pharmaceuticals (Beijing) Co. Ltd. discussed BSA-01, a bispecific antibody-drug conjugate (ADC) targeting both epidermal growth factor receptor (EGFR) and mucin-1 (MUC-1), two tumor-associated antigens that are highly co-expressed in several cancers.
Antitumor immunotherapy has notched big wins, but in a small proportion of patients. And one possible explanation for why is that approved immunotherapies are not yet planting their flag on most of the battlefields where tumors and the immune system engage in combat. At the opening AACR 2023 plenary session, Ralph DeNardo celebrated the successes of the current, mostly T-cell-based approaches, but also encouraged his colleagues to think more broadly about the antitumor immunity.
HER2 is a member of the epidermal growth factor receptor family that is overexpressed in approximately 20% of breast cancers. Trastuzumab, an anti-HER2 antibody discovered 25 years ago has become the standard of care treatment due to its beneficial results.
Researchers from Bright Peak Therapeutics AG presented the discovery and preclinical characterization of a novel first-in-class PD-1/interleukin-18 (IL-18) immunocytokine, BPT-567.
Expression of the tyrosine-protein phosphatase non-receptor type 22 (PTPN22) is restricted to hematopoietic cells where it serves critical functions in regulating T-cell signaling that have made PTPN22 the focus of potential future cancer immunotherapy.
