Gan & Lee Pharmaceuticals (SHA: 603087) has announced that China’s National Medical Products Administration (NMPA) has granted clinical trial approval for GLR1062, a first-in-class gene therapy for the treatment of adult neovascular (wet) age-related macular degeneration (nAMD). The investigational therapy utilizes a recombinant adeno-associated virus (rAAV) delivery vector to express a vascular endothelial growth factor (VEGF) antagonist in vivo via intraocular injection, representing a potentially transformative approach to managing this leading cause of vision loss in elderly populations.
Regulatory Milestone
| Item | Detail |

| Regulatory Agency | National Medical Products Administration (NMPA), China |
| Approval Type | Clinical trial authorization (Phase I/II initiation) |
| Product | GLR1062 – rAAV-delivered VEGF antagonist gene therapy |
| Indication | Neovascular (wet) age-related macular degeneration (nAMD) |
| Administration | Single intraocular injection |
| Innovation Status | First rAAV-VEGF antagonist gene therapy approved for clinical development globally |
| Market Opportunity | Addresses critical unmet need in chronic nAMD management |
Therapeutic Profile & Mechanism of Action
Gene Therapy Platform
- Vector: Recombinant adeno-associated virus (rAAV) – established safety profile in ocular gene therapy
- Transgene: VEGF antagonist designed for sustained intraocular expression
- Delivery: Single intravitreal injection providing long-term therapeutic protein production
- Mechanism: Continuous endogenous production of VEGF antagonist maintains therapeutic levels without repeated injections
Clinical Rationale
- Current Standard of Care: Monthly or bimonthly anti-VEGF injections requiring lifelong treatment burden
- Treatment Gap: ~50% of patients experience suboptimal response or treatment fatigue with current regimens
- Therapeutic Goal: Single-administration therapy providing sustained VEGF suppression for years
- Patient Benefit: Eliminates need for frequent intravitreal injections and associated complications
Market Context & Unmet Medical Need
nAMD Landscape in China
- Prevalence: Estimated 4-5 million nAMD patients in China, growing with aging population
- Annual Incidence: ~500,000 new cases annually
- Current Treatment Burden: Patients require 6-12 intravitreal injections per year indefinitely
- Healthcare System Impact: Significant resource utilization from frequent clinic visits and injections
Global Gene Therapy Context
- Pioneering Status: No rAAV-VEGF antagonist gene therapy approved anywhere globally
- Competitive Landscape: Multiple gene therapy approaches in development but none with NMPA/EMA/FDA approval
- First-Mover Advantage: Potential to establish dominant position in emerging nAMD gene therapy market
- Pricing Premium: Gene therapies typically command premium pricing reflecting curative potential
Strategic Implications for Gan & Lee Pharmaceuticals
- Innovation Leadership: Transforms company from traditional pharmaceutical manufacturer to gene therapy innovator
- Platform Technology: Establishes rAAV gene therapy capabilities for future ophthalmology and CNS applications
- Global Ambition: First-in-class status supports international regulatory filings and partnership opportunities
- Portfolio Diversification: Expands beyond diabetes and cardiovascular franchises into high-value specialty therapeutics
“This NMPA approval for GLR1062 represents a groundbreaking moment for both Gan & Lee and Chinese patients with wet AMD,” said Dr. Li Guohui, Chairman and CEO of Gan & Lee Pharmaceuticals. “By harnessing gene therapy to provide sustained VEGF suppression from a single injection, we aim to eliminate the treatment burden that currently defines nAMD management while potentially improving visual outcomes.”
