Shanghai, China, January 8, 2026 — Asieris Pharmaceuticals (Stock Code: 688176.SH), a global innovative pharmaceutical company focused on genitourinary tumors and women’s health, announces that the first patient in China has been enrolled in the Phase I clinical trial of its self-developed APL-2401 (ASN-8639 tablets) for patients with FGFR2/3-driven advanced solid tumors.
APL-2401 is a highly selective dual-target small-molecule inhibitor of Fibroblast Growth Factor Receptor 2/3 (FGFR2/3), independently developed by the Company. It is expected to offer a novel therapeutic option for patients with advanced solid tumors, such as urothelial carcinoma, cholangiocarcinoma, endometrial cancer, gastric cancer, breast cancer, ovarian cancer, non-small cell lung cancer, and other specific solid tumors.
Using Company‘s TAIDD platform and multi-structural simulation of drug targets , Asieris’ research team discovered hit compounds. Further optimization on the selective binding to FGFR2/3 led to the identification of the final preclinical candidate compound APL-2401. APL-2401 is a highly selective small-molecule inhibitor of FGFR2/3 with a non-covalent binding mode. Compared with current selective inhibitors of FGFR2 or FGFR3, APL-2401 demonstrated superior dual kinase inhibitory activity, tumor cell-killing effects, and modulation of the tumor microenvironment. Compared with pan-FGFR inhibitors, APL-2401 significantly reduced FGFR1- and FGFR4-related toxicities. Preclinical studies showed that APL-2401 exhibited robust efficacy and a wider safety window across multiple models with FGFR2/3 genetic mutations, amplifications, or overexpression. Compared with existing agents in the same class, APL-2401 demonstrated potential best-in-class advantages in potency, selectivity, safety, and drug properties. It is expected to become a blockbuster product in the field of FGFR2/3-targeted therapy.
Notably, APL-2401 is a Class 1 innovative drug under global synchronized development. Its international multi-center clinical trial design and application dossiers meet the technical standards of international clinical trial systems. It was successfully accepted into the “30-working-day review and approval pathway” specified in the Announcement on Optimizing of the Review and Approval Process for Clinical Trials of Innovative Drugs (No. 86, 2025) issued by the National Medical Products Administration (NMPA) on September 12, 2025, and received approval in just 22 working days, making it one of the first in the country to be approved under this new policy.Meanwhile, APL-2401 completed clinical trial notification with the Therapeutic Goods Administration (TGA) of Australia in December 2025.
Ms. Joanna Zhang, Chief Medical Officer of Asieris Pharmaceuticals, stated, “The team successfully completed the first patient dosing within just 15 working days after approval, which fully demonstrates the effectiveness of the new policy in accelerating R&D. Given the unmet needs in advanced solid tumors with FGFR pathway alterations, it is crucial to rapidly advance this candidate drug with ‘best-in-class’ potential into the clinic. We will accelerate the development process to benefit patients as early as possible.”
