Beigene has submitted the IND application for its anti-EGFR×c-MET×c-MET tri-specific antibody BG-T187 in China. This marks the company's first in-house tri-specific antibody entering the clinical stage. In NSCLC, BeiGene has strategically targeted numerous molecular pathways, including PD-1, TIGIT, TIM3, LAG3, OX40, PanKRASi, HPK1, PRMT5i, B7H3 ADC, CEA ADC, and EGFR degrader. BG-T187 EGFR is a critical biomarker for the diagnosis and treatment of non-small cell lung cancer (NSCLC). Beigene had not previously targeted this pathway, but they have now discovered therapeutic approaches beyond single inhibitors, such as TsAb and degraders. Prevalence of EGFRm in NSCLC BG-T187 is an anti-EGFR×c-MET×c-MET tri-specific antibody that is registered as a monotherapy or in combo with the other therapeutic agents (not disclosed) in the phase 1 trial ( NCT06598800 ).  In 2023, Beigene submitted a patent (WO2024153168) covering anti-cMET antibodies, including multispecific antibodies such as the...

 Innovent has initiated a phase 1 study (NCT06349408 ) of IBI3001, a bispecific ADC that targets B7-H3 and EGFR, in patients with solid tumors. Additionally, Innovent is conducting a phase 1 trial ( NCT05774873 ) of IBI344, a bispecific antibody that also targets B7-H3 and EGFR. Schematic overview of crosstalk between the EGFR signaling and the B7/CD28 family Recent research has suggested that the overexpression of novel B7/CD28 family proteins, including B7-H3 may be linked to EGFR signaling and could potentially lead to resistance to EGFR-targeted treatments by promoting an immune-depressed environment within the tumor microenvironment. IBI3001 According to the statement by Innovent, IBI3001 is a  site-specifically glycan-conjugated ADC that consists of a topoisomerase I inhibitor  with  multiple anti-tumor mechanisms of action : (1) enhanced EGFR signaling blockade; (2) EGFR- and B7-H3-aided payload internalization and cytotoxicity; and (3) potent bystande...

  Jing Medicine (和径医药) has submitted the IND application for HJ-002-03, an EGFR-PROTAC, intended for patients with non-small cell lung cancer in China. HJ-002 is the first PROTAC in the IND stage developed by Jing Medicine. https://doi.org/10.1016/j.ejmech.2022.114533 In 2022, Jing Medicine received IND approval for HJM-353 , an EED inhibitor, in both China and the United States, however, no clinical study has been initiated as of yet. In 2021, Jing Medicine filed a patent (WO2022268229) claiming the PROTACs targeting EGFR, ALK, and ROS1.  These CRBN-based PROTACs, designed with Brigatinib analogs that target ALK and EGFR kinases, may offer a potential new approach for treating lung cancer by inducing targeted protein degradation.  Brigatinib and Embodiments in the Patent E95 and E123 demonstrated potent degradation activity, with DC50 values around single-digit nM and achieving over 90% degradation (Dmax) for EGFR-DTC (Del19/T790M/C797S), EGFR-L...
