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.
Researchers from Arvinas Inc. and affiliated organizations presented the discovery and preclinical evaluation of ARV-766, a novel androgen receptor (AR) degrading proteolysis targeting chimera (PROTAC), being developed for the treatment of metastatic castration-resistant prostate cancer (mCRPC).
Shanghai Junshi Biosciences Co. Ltd.’s anti-PD-1 monoclonal antibody toripalimab showed positive interim event-free survival (EFS) results in a phase III study to treat patients with resectable non-small-cell lung cancer (NSCLC). This is the world’s first phase III trial that shows perioperative treatment with an anti-PD-1 monoclonal antibody significantly extends EFS of patients with resectable NSCLC, according to Shanghai-based Junshi Biosciences.
Daiichi Sankyo Co Ltd. has experienced yet another setback with its quizartinib NDA submission, as the U.S. FDA has now extended the review period by three months to July 24, 2023, to allow additional time to review requested updates to the proposed Risk Evaluation and Mitigation Strategies.
Researchers at Repare Therapeutics Inc. have prepared and tested N-(5-substituted-[(1,3,4-thiadiazolyl) or (thiazolyl)]) (substituted) carboxamide compounds acting as DNA polymerase θ (POLQ) inhibitors and thus reported to be useful or the treatment of cancer.
Research at Nextgen Bioscience Co. Ltd. has led to the identification of ectonucleotide pyrophosphatase/phosphodiesterase family member 2 (ENPP2; autotaxin) inhibitors.
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.
Researchers at 1200 Pharma LLC have undertaken preclinical analysis of KRAS G12C inhibitors in clinical phases with the aim of finding an explanation for the differences observed in therapeutic efficacy in tumor sites other than lung, including lung-derived metastases. Results pointed to potency and pharmacokinetics as key drivers of efficacy.
