Jiangsu Asieris Pharmaceuticals Co., Ltd. (SHA: 688176) announced that China’s National Medical Products Administration (NMPA) approved a Phase 1 clinical trial for APL-2401 (ASN-8639 tablets), a highly selective small‑molecule dual‑target inhibitor of FGFR2/3, in patients with advanced solid tumors driven by FGFR2/3 mutations, amplifications, or overexpression.
Regulatory Milestone
Item
Details
Approval Date
18 Dec 2025
Agency
NMPA (China)
Product
APL-2401 (ASN-8639 tablets)
Indication
Advanced solid tumors with FGFR2/3 alterations
Mechanism
Dual FGFR2/3 kinase inhibition with tumor microenvironment modulation
Innovation
First‑in‑class potential with best‑in‑class advantages in activity, selectivity, and safety
Drug Profile & Differentiation
Attribute
APL-2401
Competitive Landscape
Targets
FGFR2 and FGFR3 (dual inhibition)
Single‑target FGFR2 or FGFR3 inhibitors lack dual coverage
Selectivity
Spares FGFR1 and FGFR4, reducing off‑target toxicity
Pan‑FGFR inhibitors cause FGFR1/4‑related adverse events
Preclinical Efficacy
Excellent activity in FGFR2/3‑mutant, amplified, or overexpressed models
Demonstrates tumor killing and microenvironment modulation
Safety Margin
Wider therapeutic window vs. pan‑FGFR agents
Lower risk of hyperphosphatemia, retinopathy, and liver toxicity
Development Status
Phase 1 ready; IND approval in China
Positioned for rapid global expansion
Market Opportunity
Metric
Value
Context
FGFR2/3 Alteration Prevalence
5‑10% of solid tumors (bladder, breast, lung, gastric cancers)
~150,000 eligible patients annually in China
Global FGFR Market
$1.2 billion (2025)
Dominated by pan‑FGFR inhibitors (erdafitinib, pemigatinib)
APL-2401 Peak Sales
¥2‑3 billion (≈ US$280‑420 M) by 2032
25‑30% share of FGFR2/3‑selective segment
Competitive Advantage
Dual‑target precision with improved safety profile
Addresses resistance to single‑target FGFR inhibitors
Strategic Implications
For Asieris:Phase 1 approval validates proprietary FGFR platform; best‑in‑class potential supports premium pricing; foundation for global out‑licensing or co‑development partnerships.
For Patients:Dual‑target inhibition may overcome resistance mechanisms in FGFR‑driven tumors; spared FGFR1/4 activity reduces toxicity burden; oral tablet offers convenience.
For Market:First dual FGFR2/3 inhibitor in China; expands precision oncology toolkit beyond pan‑FGFR agents; clinical biomarker‑driven development aligns with personalized medicine trends.
