    Targeting erbB Pathways in Breast Cancer: Dual Kinase Inhibition for Brain Metastasis and Prevention of p185HER2/Neu Tumor Development. (PubMed, Breast Cancer (Dove Med Press))
    The Herceptin-resistant breast cancer cell line JIMT-1 was used in an in vivo tumor model, and MMTV-erbB2 (Fo5) transgenic mice models were used to evaluate the efficacy and safety of ER121 as neoadjuvant. ER121 is a non-toxic small-molecule erbB kinase inhibitor and holds promise as an oral and systemic therapeutic agent for treating progressive erbB-driven tumors in therapeutic settings. Moreover, ER121 shows potential as a preventive therapy in neoadjuvant settings for erbB2-associated tumors and when administered systemically can dramatically limit erbB2 brain metastases in animal models.

    TRX-221, a novel 4th-generation EGFR inhibitor for overcoming C797S mutation-mediated acquired resistance in NSCLC (AACR 2023)
    With favorable DMPK profiles, once-daily oral dosing of TRX-221 induced strong anti-tumor effects in a dose-dependent manner in a variety of osimertinib-resistant CDX and PDX models. As a reversible, selective, and broad-spectrum 4th-generation EGFR-TKI, TRX-221 is currently undergoing IND-enabling studies and shows strong potential as a therapeutic solution to treat advanced NSCLC patients harboring EGFR mutations.
