Technology Platforms

AAVarta – AI-Assisted AAV Capsid Evolution

  • Function: Proprietary AAV capsid discovery platform using machine learning to engineer novel serotypes with enhanced tissue tropism and reduced immunogenicity
  • Innovation: In silico prediction of capsid variants followed by high‑throughput in vivo screening; reduces discovery timeline from 36 months to 12 months

SODA – Silencing Oligonucleotide Design Approach

  • Function: AI‑driven design of antisense oligonucleotides (ASOs) and siRNAs for target knockdown
  • Advantage: Optimizes chemical modifications, delivery vectors, and off‑target profiling simultaneously

Clinical Pipeline

CandidateTechnologyIndicationStageKey Differentiation
EXG001-307AAV‑based gene therapySMA Type 1Pre‑IND / IND‑enablingPotential best‑in‑class vs. Zolgensma; lower vector dose, reduced liver toxicity
EXG102-031AAV‑based gene therapywAMD (wet age‑related macular degeneration)PreclinicalSingle‑ injection vs. monthly anti‑VEGF injections; sustained efficacy
EXG202AAV‑based gene therapyOcular neovascular diseases (wAMD, DME, RVO)DiscoveryPan‑ocular platform targeting multiple retinal indications
7 Additional AssetsGene therapy / oligonucleotideVarious oncology/rare diseasesDiscovery / PreclinicalDiversified pipeline leveraging dual platforms

Market Opportunity

IndicationGlobal Market Size (2026E)Target PopulationCompetitive Landscape
SMA Type 1$2.8 billion~1,200 new cases/year (US/EU/China)Novartis Zolgensma ($2.1M/dose), Roche Evrysdi (oral)
wAMD$11.6 billion20 million patients globallyRegenxbio, Adverum (gene therapy); Eylea, Lucentis (anti‑VEGF)
DME / RVO$7.2 billion10 million+ patientsSame anti‑VEGF competitors; no approved gene therapies

Financial & Strategic Positioning

  • Valuation: Pre‑money estimated at USD 500‑600 million based on comparable AI‑gene therapy companies
  • Revenue Model: Near‑term partnership revenues (platform licensing); long‑term product sales and milestones
  • Investor Base: Viva Biotech (incubator) remains largest shareholder; new investors include Hong Kong‑based family offices and biotech crossover funds
  • Manufacturing: In‑house GMP facility in Hangzhou (2,000L scale) for AAV production; capacity for clinical supply through Phase II

Competitive Advantages

  • AAVarta Platform: Novel capsids show 5‑fold higher retinal transduction and 3‑fold lower liver sequestration vs. AAV2/AAV8 in preclinical models
  • Integrated AI: SODA platform reduces oligonucleotide design cycles from 6 months to 8 weeks
  • Cost Efficiency: In‑house manufacturing reduces COGS by 40% vs. CDMO model
  • Diversification: Dual platform (gene therapy + oligonucleotide) mitigates AAV immunogenicity risks
