Most patients with non-small-cell lung cancer (NSCLC) develop acquired drug resistance to EGFR inhibitors. Osimertinib, a third-generation inhibitor, often sees its therapeutic effect reduced due to the C797S mutation of EGFR exon 20, which blocks the binding of Cys797 to osimertinib.
Tuberculosis still kills a lot of people worldwide (1.6 million deaths per year). Previous findings demonstrated that induced myeloid leukemia cell differentiation protein Mcl-1 inhibitors reduced the growth of Mycobacterium tuberculosis in human macrophages, but when inhibiting multiple proteins from the Mcl-1/Bcl-2 family, the result was more effective and in a more complex human in vitro granuloma environment.
Phenomic AI Inc. has announced new collaboration agreements to help advance drug discovery for stroma-rich tumors using its Sctx single-cell transcriptomics platform.
Researchers from Multitude Therapeutics Inc. have reported the preclinical profile of AMT-253, a MUC18-targeting antibody-drug conjugate (ADC) under development for the treatment of melanoma. It comprises the anti-MUC18 humanized antibody pAb253-H linked to T1000 exatecan payload and showed superior antitumor efficacy than the traditional vc-MMAE-based ADC AMT-253-M.
Nurexone Biologic Inc. has reported results from laboratory tests of its secondary two proprietary sequences, showing promise for the treatment of spinal cord injuries.
Current antiviral agents for COVID-19 treatment target viral proteins, which are susceptible to mutation during SARS-CoV-2 evolution. A potential strategy to fight emerging drug resistances is the development of compounds targeting host proteins that are indispensable for the viral life cycle.
Researchers at Dana-Farber Cancer Institute are advancing a fourth-generation allosteric EGFR inhibitor, EAI-432, to treat non-small-cell lung cancer driven by mutations in the EGFR gene, particularly the L858R mutation.
Proteoglycan glypican-1 (GPC1) is a tumor-associated antigen that is highly expressed in tumor tissues from patients with pancreatic ductal adenocarcinoma (PDAC), while its expression is very low on benign neoplastic lesions, chronic pancreatitis and normal adult pancreatic tissue. Researchers from Centro Di Riferimento Oncologico (CRO Aviano) and L'Università degli studi di Trieste have reported the development and preclinical characterization of AT-101, a novel complement-fixing IgM antibody targeting GPC1, as a potential immunotherapy candidate for the treatment of PDAC.
Researchers have developed a new approach for the development of improved CAR T cells with bifunctional degraders, which linked ubiquitin to an endogenous target protein. The key to the design was the use of multispecific protein degraders and E3 ligases, which increased the proliferation of CAR T cells and their antitumor potency. This combination can be adapted to different uses of cell therapies.
