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

BeBetter Med has submitted the IND application for BEBT-507, a siRNA that targets TMPRSS6, in patients with iron metabolism disorders ( Polycythemia Vera, Disease of Iron Overload, etc.) . This marks BeBetter's first potential RNAi therapy to reach the clinical stage. The second siRNA therapy targets  NAFLD/MAFLD. BEBT-507 TMPRSS6 is a serine protease expressed in the liver that negatively regulates the iron-regulatory hormone hepcidin. Using siRNA to silence TMPRSS6 can increase hepcidin levels, offering a therapeutic approach for iron overload and related conditions. TMPRSS6 BEBT-507 is a GalNac-conjugated siRNA targeting TMPRSS6 as a treatment for patients with  Polycythemia Vera and  β-thalassemia. The patent (WO2024109722 ) filed by BeBetter in 2022 showed the in vivo efficacy of several examples such as BBD-2051.210-GalNac in comparison with  Divesiran  . Patent TMPRSS6 Therapies in the Clinical Stage Different technology modalities, such as ASO, siRNA, and antibody, are bein

Beigene has submitted the IND application for the PRMT5 (Protein arginine methyltransferase 5) inhibitor BGB-58067 in China. This aligns with the plan to enter the clinic in Q4 2024. BGB-58067 BGB-58067 is a second-generation MTA-cooperative PRMT5 inhibitor with brain-penetrating and good intracranial efficacy. MTAP-deletion lung cancer and GI cancers are the target diseases for the PRMT5 inhibitor. 2nd generation PRMT5 inhibitor BG PRMT5i In 2019 and 2023, Beigene filed patents for PRMT5 inhibitors, providing several examples. Patents [Update]  In September 2024, Beigene registered a phase 1 trial ( NCT06589596 ) of BGB-58067 monotherapy in solid tumors patients. The potential of combining PRMT5 inhibitor with IO therapy (anti-PD-1, etc.) may be explored. PRMT5 Inhibitors in China Currently, no PRMT5 inhibitors are under investigation in the clinical stage. SIM0272 , discovered by Simcere, was terminated from the phase 1 trial as an R&D strategy adjustment.  GTA182 GTA182 is

Duality Biologics has initiated a trial ( NCT06554795 ) of an anti-B7H3xPD-L1 BsAb ADC, DB-1419, in the United States, Australia, and China. However, Duality Bio has not yet submitted the IND application in China. In 2023, BioNTech and DualityBio entered into a partnership to globally develop, manufacture, and commercialize two assets, including an ADC (DB-1311/BNT324) targeting B7H3. Duality and BioNTech DB-1419 DB-1419 is a bispecific antibody-drug conjugate targeting B7H3 and PD-L1. It was discovered by Duality Biologics and is still in the preclinical stage according to the pipeline on the official website.  In 2022 and 2023, Duality Biologics filed patents (WO2024140846 ) covering anti-B7H3xPD-L1 BsAb ADCs. The patent includes examples of bispecific antibody-drug conjugates comprising the following components: an anti-B7H3 and PD-L1 bispecific antibody or an antigen-binding fragment thereof, a linker unit L, and TOP1 inhibitor, with a drug-to-antibody ratio (DAR) of 4, 6, or 8.

 HUTCHMED (formerly Hutchison MediPharma) has introduced its Menin-MLL inhibitor HMPL-506 into a phase 1 trial, aiming to broaden its footprint in hematological malignancies. The company filed the IND application for HMPL-506 in January 2024 in China.  Menin binds to KMT2A, activating leukemogenic genes like HOX and MEIS1. However, when a Menin inhibitor binds to the pocket of menin and displaces KMT2A, it deactivates HOX and MEIS genes, halting the growth of leukemic cells. Targeting Menin Currently, HUTCHMED possesses several drug candidates targeting SYK, PI3Kδ, IDH1/2, BTK, CD47, and Menin, in addition to the in-licensed EZH2 inhibitor tazemetostat, all of which are part of the pipeline for blood cancers. HUTCHMED Pipeline in 2024Q1 HMPL-506 MLL gene rearrangements (MLL-r, also known as KMT2A) are found in 5%-10% of acute leukemias and are linked to a poorer prognosis. On the other hand, nucleophosmin 1 mutations (NPM1m) are the most frequent genetic changes seen in acute myeloid l

 China's CDE has cleared the IND application for WGI-0301/HC0301, which is a lipid nanoparticle (LNP) formulation of an AKT-1 antisense oligonucleotide that binds to AKT-1 mRNA discovered by WhiteOak, a subsidiary of Haichang Biotech. This clearance is for use in patients with hepatocellular carcinoma. The product (RX-0301), along with WGI-0201/HC0201 (RX-0201) and WGI-0047 (RX-0047), was licensed from Rexahn Pharmaceuticals (now Ocuphire Pharma) in 2018. WGI-0301 X-0301 is a nano-liposomal formulation of RX-0201, an antisense oligonucleotide compound designed to enhance delivery to target mRNA encoding Akt-1. RX-0201 works by binding to the mRNA, thereby inhibiting its transcription and the subsequent production of Akt-1 protein.  RX-0201 Rexahn explored the clinical use of RX-0201 in patients with pancreatic cancer and renal cell cancer before 2018.  The median PFS in evaluable patients with mRCC treated with RX-0201 in combination with everolimus was 4.9 months, which is compar
