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 >

On-target, off-tumor toxicity is a specific type of toxic side effect that limits the anticancer applicability of chimeric antigen receptor (CAR) T cells. In our latest publication, WuXi AppTec scientists contributed to a study describing how the tumor-targeting specificity and activity of T cells with a CAR (consisting of an antibody that catalytically forms a …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 >

Salt-inducible kinases (SIKs) have recently emerged as key regulators of oncogenesis, inflammation, and immune responses, making these enzymes an important drug target. The isoform SIK3 is a novel regulator of tumor-intrinsic resistance to cytotoxic T cell attack. To support the discovery of novel SIK3 modulators, WuXi AppTec offers an integrated platform of ready-to-go biophysical assays …Read More >

Cereblon (CRBN) forms an E3 ligase complex together with DDB1, CUL4, and RBX1. CRBN functions as a substrate receptor of this complex for the recognition and binding of proteins targeted for ubiquitination and proteasomal degradation.  To support the discovery of CRBN-DDB1 proteolysis-targeting chimeras and molecular glues, WuXi AppTec offers an integrated platform of ready-to-go assays …Read More >

Within the PI3K family, the heterodimer comprising the p110-α catalytic and p85-α regulatory subunits (encoded by PIK3CA and PIK3R1) is essential in the regulation of cellular proliferation and carcinogenesis.  To support the discovery of novel PI3K inhibitors, WuXi AppTec offers an integrated platform of ready-to-go assays and Spectral Shift technology within Dianthus, an affinity screening …Read More >
