Management Comments

• George Lasezkay, PharmD, JD, President and Chief Executive Officer, stated that they are making outstanding progress advancing their differentiated suprachoroidal delivery pipeline.
• George Lasezkay also noted that the recent positive results from the ODYSSEY trial establish CLS-AX as a Phase 3 ready asset in the large and growing wet AMD market.
• Victor Chong, M.D., MBA, Chief Medical Officer and EVP, Head of Research & Development, mentioned that their research team is evaluating small molecules for the potential treatment of geographic atrophy (GA).

Industry Context

The announcement highlights the growing interest in suprachoroidal drug delivery for retinal diseases, with Clearside positioning itself as a leader in this space. The commercial partnership with Santen, a global ophthalmic company, underscores the potential of Clearside's technology. The focus on wet AMD and geographic atrophy aligns with significant market opportunities in ophthalmology.

Comparison to Industry Standards

• The positive results from the ODYSSEY trial for CLS-AX are competitive with other treatments for wet AMD, particularly in the area of extended duration.
• The commercial licensing agreement with Santen is similar to other deals in the pharmaceutical industry, where smaller companies partner with larger ones for commercialization.
• The focus on suprachoroidal delivery is a differentiated approach compared to traditional intravitreal injections, which are the current standard of care for many retinal diseases.
• The company's research into small molecules for geographic atrophy (GA) is in line with industry trends, as GA is a significant unmet need in ophthalmology.
• The company's cash position of $23.6 million is relatively low compared to other companies in the biotechnology sector, which may require additional capital raises in the future.

Management Changes

Stakeholder Impact

• Shareholders will likely react positively to the successful trial results and commercial partnership.
• Employees may be encouraged by the company's progress and future prospects.
• Patients with wet AMD and other retinal diseases may benefit from the development of new treatments.
• Partners such as Santen, Arctic Vision, and REGENXBIO will be impacted by the progress of their collaborations with Clearside.

Next Steps

• Clearside plans to conduct an End-of-Phase 2 meeting with the FDA in early 2025 to align on the essential components of their Phase 3 program for CLS-AX.
