Bio‑Thera NDA for VEGF‑A165 Antibody Targets $2B Wet AMD Market in China

Bio‑Thera NDA for VEGF‑A165 Antibody Targets $2B Wet AMD Market in China

Bio‑Thera Solutions (SHA: 688177) submitted a New Drug Application (NDA) to China’s National Medical Products Administration (NMPA) for Velasitaximab injection (BAT5906), a recombinant humanized anti‑VEGF‑A165 monoclonal antibody, for the treatment of neovascular (wet) age‑related macular degeneration (nAMD).

Regulatory Milestone

ItemDetails
Submission Date19 Dec 2025
AgencyNMPA (China)
ProductVelasitaximab injection (BAT5906)
IndicationNeovascular (wet) AMD
InnovationIndependently developed IgG1‑type full‑length antibody (149 kDa)
MechanismBinds VEGF‑A165, blocking angiogenesis and endothelial cell proliferation

Drug Profile & Preclinical Data

AttributeBAT5906Competitive Landscape
Antibody TypeRecombinant humanized IgG1, 149 kDaSimilar to aflibercept (Eylea) and ranibizumab (Lucentis)
TargetVEGF‑A165 isoformPrecision targeting vs. pan‑VEGF‑A agents
MechanismBlocks VEGF‑receptor binding → inhibits angiogenesisStandard of care for nAMD
AdministrationIntravitreal injectionAligns with existing anti‑VEGF regimen
Preclinical EfficacyIn‑vitro models show potent inhibition of endothelial cell proliferation and neovascularizationValidated mechanism
DifferentiationFirst domestic‑developed VEGF‑A165‑selective antibodyPotential for cost advantage vs. imported biologics

Market Opportunity

MetricValueContext
China nAMD Prevalence~3‑5 million patients (2025)Growing at 5‑7% CAGR due to aging population
China Anti‑VEGF Market¥15‑20 billion (≈ US$2.1‑2.8 B)Dominated by Eylea, Lucentis, and off‑label Avastin
BAT5906 Peak Sales¥2‑3 billion (≈ US$280‑420 M) by 203010‑15% share if priced 30‑40% below imports
Competitive AdvantageDomestic manufacturing cost advantage; NRDL eligibilityFaster market access and reimbursement
Launch TimelinePotential 2027‑2028 approvalFiling under standard NDA pathway

Strategic Implications

  • For Bio‑Thera: NDA submission validates antibody platform beyond biosimilars; VEGF‑A165 selectivity positions for differentiated marketing; potential for global expansion if China data supports US/EU filings.
  • For Patients: Oral not available; injectable offers alternative to existing anti‑VEGF agents; cost‑effective option could improve access in tier‑2/3 cities.
  • For Market: First domestic VEGF‑A165 antibody challenges multinational dominance; NRDL negotiation likely in 2026; biosimilar pressure on Eylea/Lucentis creates pricing headroom.
