[VIRTUAL] An open-label, phase II study of patritumab deruxtecan (HER3-DXd, U3-1402) in patients (pts) with previously treated advanced/metastatic colorectal cancer (CRC). () - Dec 9, 2020 - Abstract #ASCOGI2021ASCO_GI_408; P2 ORR will be summarized with the 2-sided 95% confidence interval. Secondary objectives include the evaluation of efficacy as measured by ORR (assessed by investigator according to RECIST v1.1), duration of response, time to tumor response, disease control rate, progression-free survival (assessed by investigator and BICR according to RECIST v1.1), overall survival, safety and tolerability, HER3 protein expression in tumor tissue and relationship with efficacy, and pharmacokinetic properties.

Journal, PD(L)-1 Biomarker, IO Biomarker: U3-1402 sensitizes HER3-expressing tumors to PD-1 blockade by immune activation. (Pubmed Central) - Jul 22, 2020 Further, clinical analyses indicated that tumor-specific HER3 expression was frequently observed in patients with PD-1 inhibitor-resistant solid tumors. Overall, U3-1402 is a promising candidate as a partner of immunotherapy for such patients.

EGFR inhibition enhances the cellular uptake and antitumor activity of the novel HER3 antibody drug conjugate U3-1402 (Virtual Meeting II: E-Posters) - May 16, 2020 - Abstract #AACRII2020AACR-II_1059; P1 HER3 is frequently over expressed in EGFR-mutant NSCLC.U3-1402 is an antibody-drug conjugate (ADC) comprised of HER3-targeting antibody (patritumab) linked to a topoisomerase I inhibitor (DX-8951 derivative, or DXd)...We aimed to develop a preclinical strategy to enhance the efficacy of U3-1402.Pre-treatment with EGFR TKIs (gefitinib or osimertinib) increased HER3 membrane levels in six different EGFR-mutant cell lines by increasing both the amount of HER3 positive cells and the intensity of HER3 expression...In vivo experiments evaluating the antitumor efficacy of the combination of osimertinib and U3-1402 are currently underway.Our studies reveal that EGFR inhibitor treatment increased membrane expression of HER3 which was associated with enhanced internalization of U3-1402 in EGFR-mutant NSCLC. The combination of osimertinib and U3-1402 may be an effective treatment approach and should be evaluated in future clinical trials in patients with EGFR-mutant NSCLC.
