Axcynsis Therapeutics Pte Ltd. has described antibody-drug conjugates comprising an antibody or antigen-binding fragment targeting alkaline phosphatase placental type (ALPP) and/or alkaline phosphatase, germ cell type (ALPPL2) covalently linked to a cytotoxic agent through a linker reported to be useful for the treatment of cancer.
In recently published work from Air Force Medical University, analysis of tumor tissues isolated from different patient-derived xenografts revealed significantly increased expression of FXYD5 in the metastatic tumors compared to the primary tumors, and analysis of patient database confirmed significantly elevated expression of FXYD5 in gastric cancer tissues compared to normal gastric tissues.
Astrazeneca AB has synthesized antibody-drug conjugates comprising an antibody or antigen-binding fragment covalently linked to cytotoxic moieties through enzymatically cleavable linkers reported to be useful for the treatment of cancer.
Mindrank Therapeutics (Suzhou) New Drug Research & Development Co. Ltd. has disclosed cellular tumor antigen p53 (TP53) (Y220C mutant) stabilizers reported to be useful for the treatment of cancer.
Patients with metastatic or unresectable gastric cancer are usually given 5-fluorouracil (5-FU) and platinum-based chemotherapy, but patients with advance disease usually have a poor prognosis. The use of chemotherapy increased the levels of cyclooxygenase-2 in tumor cells, which in turn increase the levels of prostaglandin E2 (PGE2) in the tumor microenvironment. When PGE2 binds to their receptors EP1 to EP4 on immune cells, it triggers an immunosuppressive tumor microenvironment. The use of the EP2 and EP4 dual antagonist OCT-598 was tested in the preclinical setting for gastric cancer.
Ona Therapeutics SL is accelerating development of its first-in-class antibody-drug conjugate (ADC) therapeutics, targeting novel tumor-specific markers to eliminate hard-to-treat, resistant cancer cells for multiple large solid tumor types.
Xilio Therapeutics Inc. has announced three wholly owned preclinical programs for masked T-cell engagers targeting prostate-specific membrane antigen (PSMA), claudin 18.2 (CLDN18.2) and six-transmembrane epithelial antigen of prostate 1 (STEAP1).
Multiple molecular pathways play a role in gastric cancer development, influencing how genetic and environmental factors interact to drive tumor growth and progressiA recent study by researchers at King Khalid University investigated a single-agent approach to simultaneously inhibit Akt and MEK1 pathways instead of using two different small molecules, which could potentially lead to increased toxicity.
Some favorable and some not-so-great results from separate midstage trials testing the anti-dickkopf homolog 1 antibody sirexatamab in combo regimens for two types of gastrointestinal tumors vexed Leap Therapeutics Inc. (NASDAQ:LPTX), shares of which ended Jan. 28 at 66 cents, down $1.60, or 71%.
