Industry Context

The merger comes as the anti-VEGF market for retinal diseases is growing, with a significant unmet need for longer-acting and more effective therapies. The combined company aims to address this need with TH103, a novel therapy with promising preclinical data.

Comparison to Industry Standards

• Preclinical data suggests TH103 may offer longer-acting and increased anti-VEGF activity compared to aflibercept, potentially addressing the issue of suboptimal real-world outcomes due to undertreatment.
• The combined company will be competing with established players in the retinal disease space, including companies like Regeneron (aflibercept) and Roche (ranibizumab and faricimab).
• The Phase 1 clinical trial of TH103 will be crucial in determining its safety and efficacy compared to existing treatments.
• The combined company will need to demonstrate a clear clinical advantage and a favorable safety profile to gain market share in the competitive anti-VEGF market.
