SHANGHAI, July 21, 2025
SHANGHAI , July 21, 2025 /PRNewswire/ -- DualityBio (HKEX Stock Code: 9606.HK) announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to its next-generation HER3-targeting antibody-drug conjugate (ADC) DB-1310 . This designation is for the treatment of adult patients with advanced, unresectable or metastatic nonsquamous non-small cell lung cancer (nsqNSCLC) with an EGFR exon 19 deletion or L858R mutation with disease progression on or after treatment with a third-generation EGFR tyrosine kinase inhibitor (TKI) and platinum-based chemotherapy.
DB-1310 is a novel ADC targeting HER3 developed using DualityBio's proprietary DITAC platform. In June 2025 , Dr. Aaron E. Lisberg from the University of California, Los Angeles ( UCLA ) presented the first-in-human Phase I/IIa clinical trial data (NCT05785741) of DB-1310 in an oral session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The results demonstrated encouraging efficacy and a manageable safety profile in patients with advanced solid tumors who had failed standard therapies.
Dr. Hua Mu, Global Chief Medical Officer of DualityBio, stated : " DB-1310 demonstrated encouraging clinical efficacy and manageable safety in patients with EGFRm nsqNSCLC and multiple solid tumors. It is noteworthy that preclinical investigations of DB-1310 in combination with EGFR TKIs and other anticancer agents have also demonstrated robust synergistic tumor suppression activity. We will spare no effort to accelerate the clinical development of DB-1310 and look forward to its potential, as a next-generation HER3 ADC, to become a novel therapeutic option for a broad population of cancer patients."
