CSPC Megalith Biopharmaceutical Co. Ltd. has disclosed antibody-drug conjugates comprising a humanized monoclonal antibody targeting nectin-4 covalently linked to cytotoxic agents through a linker. They are reported to be useful for the treatment of cancer.
Impact Therapeutics (Shanghai) Inc. has divulged substituted tricyclic compounds acting as poly(ADP-ribose) polymerase (PARP; ARTD) inhibitors reported to be useful for the treatment of cancer.
T cells do not have the last word in some breast cancers. According to a study from the University of Pittsburgh, the key to estrogen receptor positive (ER+) breast tumors are macrophages, not T cells, and targeting them could prevent immunotherapy failure in this type of cancer.
In the March 2023 issue of Science Immunology, researchers working at the City of Hope National Medical Center reported on the discovery the mechanisms by which the spliced X-box–binding protein 1 (XBP1s) served essential functions in the IL-15-dependent survival of natural killer (NK) cells. Since XBP1s is known to play critical roles in MHCII expression, the unfolded protein stress response, and ultimately tumorigenesis, the study provided deep insights into the understanding of NK cell biology with translational potential.
Previous studies have implicated OBSCN in breast tumorigenesis and have also demonstrated that low OBSCN levels correlate with significantly reduced overall and relapse-free survival in breast cancer patients. In a recent study, researchers from Memorial Sloan Kettering Cancer Center aimed to investigate the mechanisms involved in the regulation of OBSCN.
Zhejiang Medicine Co. Ltd.’s subsidiary, Novocodex Biopharmaceuticals Inc., reported positive phase III study results for its humanized anti-HER2 monoclonal antibody-drug conjugate, ARX-788, in the treatment of patients with HER2-positive locally advanced or metastatic breast cancer in China.
Yiteng Pharmaceutical Industry Taizhou Co. Ltd. has synthesized cyclin-dependent kinase 7 (CDK7) inhibitors reported to be useful for the treatment of cancer.
Startup Metsystem ApS received €500,000 (US$529,080) from Denmark’s Bioinnovation Institute (BII) that will allow the company to conduct trials to validate its personalized prognosis platform for cancer metastasis. An organ-specific assessment of the metastasis potential of a patient’s primary tumor would enable clinicians to better balance the trade-off between providing the potentially life-extending benefit of preventative chemotherapy to those at higher risk and avoiding the adverse effects from chemotherapy in those who are unlikely to need it.
