On May 16, 2018 Genosco, a clinical-stage biotechnology company focused in immunology and oncology, reported that the abstract from a Phase 1/2 study evaluating YH25448 (GNS-1480) in patients with advanced Non-Small Cell Lung Cancer (NSCLC) is now available on the website of the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. YH25448 (GNS-1480), Genosco’s 3rd-generation EGFR-TKI candidate partnered for clinical development and commercialization with Yuhan Corporation, is an oral, potent, irreversible EGFR-TKI that is highly selective for activating (EGFRm) and T790M resistance mutations.

"We are encouraged by the safety and efficacy results shown in these data and look forward to the presentation of the full data set which will inform the future clinical trials," said Jong Sung (John) Koh, Ph.D., Genosco CEO.
Results from an open-label, multi-center Phase 1/2 study of YH25448 (GNS-1480) for patients with advanced NSCLC with or without CNS metastases will be presented in a poster session (Abstract 9033) by Byoung Chul Cho, M.D., Ph.D., Division of Medical Oncology, Department of Internal Medicine, Yonsei Cancer Center, Yonsei University College of Medicine, Seoul, Republic of Korea, at ASCO (Free ASCO Whitepaper) in Chicago. The poster (#356) is titled YH25448, a 3rd-generation EGFR-TKI, in patients with EGFR-TKI-resistant NSCLC: Phase I/II study results and will be presented in the Lung Cancer—Non-Small Cell Metastatic session on Sunday, June 3, 2018, 8:00 AM – 11:30 AM CT.
A total of 105 patients with EGFRm advanced NSCLC with acquired resistance to EGFR-TKIs with or without brain metastasis were enrolled in a Phase 1/2 study with dose-escalation and expansion cohorts.
Updated data will be presented at ASCO (Free ASCO Whitepaper).
About YH25448
YH25448 (GNS-1480) is an oral, potent, highly mutant-selective and irreversible, investigational 3rd-generation EGFR-TKI that penetrates the blood-brain barrier (BBB). It targets the activating EGFR mutations Del19 and L858R, as well as the T790M mutation, while sparing wild type. EGFR mutations are present in approximately 10-15% of NSCLCs. YH25448 (GNS-1480) is being evaluated in advanced NSCLC as both first- and second-line treatments.
