A novel bispecific immunotherapy developed by Roche AG to target pancreatic cancer showed promising results combined with radiation therapy in preclinical trials carried out at the University of Colorado.
Researchers from Abbvie Inc. recently presented the discovery and preclinical evaluation of a novel CD19-targeting glucocorticoid receptor modulator (GRM) agonist antibody-drug conjugate (ADC), ABBV-319, being developed for the treatment of B-cell malignancies.
Claudin 18.2 (CLDN18.2) is involved in the formation of tight junctions and is expressed in normal gastric mucosa, maintaining its expression during malignant transformation of the gastric epithelium. It is also aberrantly expressed in other tumor types, such as esophageal, pancreatic and lung adenocarcinoma, making it an attractive target for cancer immunotherapy.
Tumor-associated calcium signal transducer 2 (TROP2), a clinically validated target in oncology, is a glycoprotein overexpressed in several solid tumors such as breast, lung, pancreatic, ovarian and prostate cancer. TROP2 antibody-drug conjugates (ADCs) have shown significant efficacy in a large number of cancer types but still are linked to substantial safety issues.
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is an inhibitory factor on natural killer (NK) and T cells and is expressed in several cancer types and immune cells such as macrophages and neutrophils. Researchers from Suzhou Neologics Bioscience Co. Ltd. have investigated CEACAM1 as a potential target for cancer immunotherapy.
High levels of adenosine known to stimulate tumor immunoevasion are formed by the ecto-5’-nucleotidase enzyme (CD73) conversion of adenosine monophosphate to adenosine. CD73 is a cell surface enzyme that is overexpressed in many cancer types where this overexpression has been correlated with a poor prognosis.
Researchers from Jacobio Pharmaceuticals Co. Ltd. have reported preclinical data for JAB-X1800, an immunostimulatory antibody-drug conjugate (iADC) targeting CD73. JAB-X1800 was developed using an anti-CD73 monoclonal antibody (MAb) for targeted delivery of a highly potent noncyclic dinucleotide STING agonist payload, JAB-27670.
