- Duration: Provides continuous drug release for up to 36 months, reducing treatment burden vs. monthly anti‑VEGF injections
- Efficacy: Iluvien (US approved) demonstrated visual acuity improvement in 30‑40% of DME patients and reduced injection frequency by 70%
- Bo’ao Advantage: Pilot zone approval allows treatment of paying patients while generating real‑world evidence for NMPA review
Market Opportunity & Competitive Landscape
| Parameter | China | Global |
|---|---|---|
| DME Patients (2026E) | 5.2 million | 21.0 million |
| Anti‑VEGF‑Eligible | 2.8 million | 11.5 million |
| Sustained‑Release Implant Penetration | <2 % | 12 % |
| Market Value (2030E) | ¥45 billion | $12.5 billion |

Key Competitors:
- Anti‑VEGF Injections: Eylea, Lucentis, Beovu – dominate China market but require monthly dosing
- Ozurdex (Allergan) – 6‑month dexamethasone implant, limited DME efficacy
- Yutiq (EyePoint) – non‑DME indication, shorter duration
- OT-703 – First 3‑year implant in China; differentiated convenience
Strategic Positioning
- Manufacturing: Ocumension’s Suzhou facility (capacity 500,000 implants/year) will produce OT-703 for China; GMP certification achieved in 2025
- Clinical Development: Real‑world study data will support NDA submission to NMPA by Q4 2026; Phase III bridging trial vs. Iluvien planned for 2027
- Commercial Reach: 800‑person ophthalmology sales force established for existing products; OT-703 launch targeted for Q3 2027
- Reimbursement Strategy: Positioning as premium DME therapy (¥15,000‑18,000 per implant) with NRDL Category 1 negotiation planned for 2028
