New Data Insights from Clearside Biomedical's Recent Trial
Clearside Biomedical, Inc. (NASDAQ: CLSD), a pioneering biopharmaceutical company, is making significant strides in the realm of ocular health. The company, focused on innovatively delivering therapies to the back of the eye through the suprachoroidal space (SCS), has unveiled crucial insights from the ODYSSEY Phase 2b clinical trial presented at the recent Angiogenesis, Exudation, and Degeneration 2025 meeting. This meeting serves as a key platform for advancing the understanding and treatment of sight-threatening diseases.
Overview of the ODYSSEY Phase 2b Clinical Trial
The ODYSSEY trial was a meticulous, randomized, double-masked, parallel-group study that spanned 36 weeks. It evaluated the efficacy of CLS-AX, an axitinib injectable suspension, in individuals diagnosed with neovascular age-related macular degeneration (wet AMD). With a total of 60 participants, the trial aimed to assess the performance of CLS-AX against the traditional treatment of aflibercept.
Significant Findings from the Trial
Roger Goldberg, MD, MBA, from Bay Area Retinal Associates Medical Group, shared compelling data from the trials, highlighting two subgroup analyses essential for informing the design of upcoming Phase 3 clinical trials. The first analysis focuses on the positive outcomes observed with CLS-AX administration, revealing that a notable percentage of treatment-naïve patients maintained stable visual acuity with minimal interventions.
Encouraging Subgroup Analyses Results
The outcomes from the first subgroup analysis emphasized the benefits of targeting treatment-naïve patients. Impressively, during the ODYSSEY trial, 67% of participants receiving CLS-AX did not require additional treatment for six months. This significant finding suggests that CLS-AX has the potential to simplify treatment protocols and improve patient compliance while focusing on a broader population base.
Understanding the Need for Exclusion Criteria
Further insights emerged from the second subgroup analysis, which suggests the advantage of excluding certain participants from the Phase 3 trial. This analysis pointed out that participants with significant non-disease related changes in best corrected visual acuity could skew the results. By refining the participant criteria, Clearside aims to enhance the reliability of Phase 3 trial outcomes.
Future Directions for CLS-AX
Victor Chong, MD, MBA, Clearside’s Chief Medical Officer, articulated the importance of these analyses in shaping future clinical directions. These insights will directly inform the design strategies for the Phase 3 non-inferiority trials, ensuring that the data obtained translates effectively into real-world treatment scenarios.

About CLS-AX and Its Mechanism
CLS-AX represents a proprietary formulation of axitinib designed for suprachoroidal injection, enabling novel delivery strategies that may surpass existing treatments. As a potent tyrosine kinase inhibitor, axitinib blocks multiple VEGF receptors integral to the progression of retinal diseases like wet AMD.
Potential Advantages Over Current Treatments
This new approach stands to offer various therapeutic benefits over traditional solutions by targeting disease processes more efficiently and minimizing potential risks associated with non-targeted treatments. The therapeutic implications could vastly improve outcomes for patients who have limited success with current therapies.
About Clearside Biomedical, Inc.
Clearside Biomedical, Inc. is dedicated to transforming the treatment landscape for ocular diseases. By utilizing its proprietary SCS Microinjector, the company is committed to enhancing patient outcomes through innovative delivery methods. Currently, the company is also working on additional therapies targeting other retinal diseases, further solidifying its position as a leader in ophthalmic innovation.
