SITC Poster #466: Mutant KRAS is linked to PD-L1 expression, and oncogenic RAS signaling promotes an immunosuppressive tumor microenvironment by upregulating PD-L1 expression. Consequently, combining KRAS G12C inhibitors with immune checkpoint blockers shows promising benefits. To better understand the mechanisms underlying the combined inhibition of KRAS G12C inhibitor AMG 510, and anti-PD-1 antibody nivolumab, LU-01-0361 …Read More >

DNA-dependent protein kinase (DNA-PK) plays an important role in the overall survival and proliferation of cells, making this enzyme an intriguing target for the treatment of a variety of cancers.  In our latest publication, WuXi AppTec scientists contributed to the discovery and characterization of ZL-2201, a potent and highly selective small molecule DNA-PK inhibitor.  In …Read More >

Despite the robust clinical activity exerted by osimertinib, a majority of patients eventually exhibit disease progression while receiving this drug.  Resistance to osimertinib includes both on-target and off-target mechanisms.  With the use of osimertinib for advanced EGFR-mutant NSCLC increasing, the development of targeted therapies toward osimertinib resistance represents an unmet medical need.  To support research …Read More >

Antibody‒drug conjugates (ADCs), which combine the advantages of monoclonal antibodies with precise targeting and payloads, show great potential as cancer therapies.  However, primary and secondary resistance is frequently observed, and development of next generation ADCs necessitates the establishment of resistant tumor models.  WuXi AppTec offers validated, Enhertu-induced resistant tumor models to support project teams focused …Read More >

Introduction: Nucleic acid therapies can regulate the expression level or activity of disease-related targets at the genetic level, offering advantages such as a wide target range, programmability, and rapid iteration.  However, the wide application of nucleic acid drugs still faces many challenges, including delivery efficiency and off-target effects. To address these challenges, the Oncology-Immunology team …Read More >

Cell migration, invasion, and adhesion are pivotal steps in cancer metastasis.  To support research in this field, WuXi AppTec offers in vitro transwell migration and invasion assays using multiple cell types for assessing cell migratory behavior.  In addition, our in vivo metastasis panel includes a broad range of brain, bone, and liver xenograft models covering …Read More >

Oncolytic viruses (OVs) are emerging as a promising therapeutic approach for treating cancer. OVs are capable of both tumor-specific cell lysis and immune stimulation and can be optimized for enhanced tumor selectivity.  WuXi AppTec offers a comprehensive platform of OV-related services, including virus engineering and validation, immune profiling and lysis assays, tumor cell selectivity assays, …Read More >

WuXi AppTec offers a full range of services to characterize bispecific antibodies and bispecific T cell engagers (BiTEs).  Our comprehensive platform includes cell line selection and target expression, assessment of binding affinity (SPR, flow cytometry), in vitro activity testing (T cell activation, cytokine release, cytotoxicity), and evaluation of in vivo efficacy (using HSC and PBMC …Read More >

We have established an enzalutamide-resistant (LNCaP AR-F877L mutation) KI prostate cancer model to support the development of next-generation therapeutics.  An LNCaP AR-F877L KI cell line was shown to be resistant to enzalutamide, and in vivo animal validation studies demonstrated that enzalutamide was not efficacious to prevent tumor growth using this drug-resistant model. Check out our …Read More >
