  Content	Clearside Biomedical, Inc. (Nasdaq: CLSD), a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS ® ), announced today that the ODYSSEY Phase 2b clinical trial of CLS-AX (axitinib injectable suspension) for the treatment of neovascular age-related macular degeneration (wet AMD) achieved both its primary and secondary outcomes. In participants who received CLS-AX delivered suprachoroidally, best corrected visual acuity (BCVA) and ocular anatomy (central subfield thickness) were stable up to 6 months compared to participants who received aflibercept. In addition, CLS-AX demonstrated a well-tolerated safety profile to Week 36 inclusive of mandatory re-dosing of CLS-AX at Week 24. “We are very excited to report positive topline data from our successful ODYSSEY Phase 2b trial,” said George Lasezkay, PharmD, JD, President and Chief Executive Officer, Clearside Biomedical. “These encouraging results strongly support advancing our CLS-AX wet AMD program into Phase 3 development and provide further evidence of the potential benefits of delivering medicines to the back of the eye using our proprietary SCS Microinjector ® . We achieved our primary outcome of maintaining stable BCVA throughout the trial as measured by the mean change in BCVA from baseline to Week 36. CLS-AX consistently reduced the frequency of injections after the initial dose of CLS-AX with approximately 90% of CLS-AX participants not requiring any additional treatment up to 4 months, 81% not requiring any additional treatment up to 5 months, and 67% not requiring any additional treatment up to 6 months before mandatory re-dosing at Week 24. We believe this data supports our goal to potentially provide a safe, convenient wet AMD treatment option with the advantage of a flexible maintenance dosing regimen between 3 to 6 months. We look forward to continuing to analyze the results and share additional data analysis with the retina community at upcoming medical meetings.” Victor Chong, M.D., MBA, Chief Medical Officer of Clearside, added, “CLS-AX demonstrated extended duration and stable vision and anatomic measures throughout the trial in a difficult-to-treat patient population with reading center confirmed active disease early in their treatment journey. ODYSSEY confirmed the ability to administer multiple doses of CLS-AX from 12 weeks up to 36 weeks with a well-tolerated safety profile. We believe the ability to deliver multiple doses as needed between 12 and 36 weeks is a key differentiator from other treatments in development. In the trial, we observed that CLS-AX, delivered into the suprachoroidal space using our SCS Microinjector ® , can be flexibly dosed similar to current biologic treatments, but has the potential to last longer because it is a highly potent tyrosine kinase inhibitor that achieves pan-VEGF blockade. Our goal is to provide a new and important treatment option with meaningful efficacy, safety, and delivery benefits for patients and retina specialists. These topline results provide valuable data in wet AMD with repeat dosing data to better inform our planned Phase 3 program design.” David M. Brown, M.D., Director of Research, Retina Consultants Houston, commented, “These data are encouraging and demonstrate that suprachoroidal CLS-AX may have sustained durability beyond our currently approved agents. The positive safety profile, potential flexible dosing and delivery of CLS-AX directly to the back of the eye via Clearside's SCS Microinjector has the potential to improve the treatment landscape for patients and physicians looking for a long-acting treatment for wet AMD.” ODYSSEY Topline Data Summary ODYSSEY was a randomized, double-masked, parallel-group, active-controlled, multicenter, 36-week, Phase 2b clinical trial in participants with wet AMD previously treated with intravitreal anti-vascular endothelial growth factor (VEGF) standard of care therapy. A total of 60 participants were treated for 36 weeks and randomized to either CLS-AX (1 mg) or aflibercept (2 mg) with a 2:1 randomization schedule (40 participants in CLS-AX arm and 20 participants in aflibercept arm). CLS-AX was administered by suprachoroidal injection via Clearside's SCS Microinjector, and aflibercept was administered via intravitreal injection. Participants in the trial were determined to have active disease with a median duration of wet AMD diagnosis of 9.9 months. Eligible participants underwent diagnostic imaging at their screening visit, followed by masked reading center confirmation of persistent active disease. Primary and Secondary Outcomes The ODYSSEY trial achieved its primary and secondary outcomes including the mean change from baseline in BCVA, changes from baseline in visual function and ocular anatomy, the need for supplemental treatment, treatment burden as measured by total injections over the trial duration, and safety measures. CLS-AX Efficacy Results Maintained stable BCVA throughout the trial as measured by the mean change in BCVA from baseline to Week 36. Maintained stable central subfield retinal thickness (CSRT) throughout the trial as measured by the mean change in CSRT from baseline to Week 36, as confirmed by the independent reading center. CLS-AX Durability Results CLS-AX participants not requiring any additional treatment: 100% up to 12 weeks (3 months); n=40/40 90% up to 16 weeks (4 months); n=35/39 81% up to 20 weeks (5 months); n=30/37 67% up to 24 weeks (6 months) before mandatory re-dosing at Week 24; n=26/39 Reduced injection frequency by approximately 84% compared to the average monthly injections in the 24 weeks prior to screening CLS-AX Safety and Tolerability Results Well-tolerated safety profile through 36 weeks that included mandatory re-dosing of CLS-AX at Week 24 No ocular serious adverse events (SAEs) or treatment-related SAEs No drug or procedure-related ocular SAEs No reported drug or procedure-related systemic SAEs No endophthalmitis No retinal vasculitis Positive adverse event profile Similar discontinuation rates between treatment and comparator groups Conference Call & Webcast Details Clearside will host a webcast and conference call with accompanying slides today at 8:00 A.M. ET, including comments by management and key opinion leader Roger Goldberg, M.D., MBA, who is a board-certified retinal surgeon at the Bay Area Retinal Associates Medical Group.

About CLS-AX (axitinib injectable suspension) Clearside is developing CLS-AX as a longer-acting therapy for the treatment of retinal diseases. CLS-AX (axitinib injectable suspension) is a proprietary suspension of axitinib for suprachoroidal injection. Axitinib is a tyrosine kinase inhibitor (TKI), currently approved as an oral tablet formulation to treat advanced renal cell carcinoma, that achieves pan-VEGF blockade, directly inhibiting VEGF receptors-1, -2, and -3 with high potency and specificity. Clearside believes this broad VEGF blockade may have efficacy advantages over existing retinal therapies by acting at a different level of the angiogenesis cascade and may benefit patients who sub-optimally respond to current, more narrowly focused anti-VEGF therapies. Suprachoroidal injection of this proprietary suspension of axitinib has demonstrated meaningful potential in preclinical studies in multiple species, and in both Phase 1/2a and Phase 2b wet AMD clinical trials in which CLS-AX was well tolerated and demonstrated a positive safety profile. With suprachoroidal administration of axitinib, there is the potential to achieve prolonged duration and targeted delivery to affected tissue layers by compartmentalizing axitinib behind the retina, thereby limiting drug exposure to the front of the eye. About Age-Related Macular Degeneration (AMD) Age-related macular degeneration causes a progressive loss of central vision and is the most common cause of legal blindness in individuals over age 55. Neovascular AMD (wet AMD) is generally caused by abnormal blood vessels that leak fluid or blood into the macula, the part of the retina responsible for central vision, and accounts for the majority of vision loss in patients with this disorder. Approximately 11 million patients in the U.S. are living with AMD , and about 10% of all patients with AMD have the wet form . Current treatments require life-long, frequent injections to maintain efficacy. This treatment regimen tends to cause a treatment burden for patients resulting in reduced compliance and under-treatment leading to potentially limited outcomes. In the U.S., the total economic impact of late-stage AMD is estimated to be approximately $49 billion, with the majority of costs attributed to lower productivity related to job loss or job reduction due to the condition Sources Pennington, Katie L and DeAngelis, Margaret M, Eye and Vision, Epidemiology of age-related macular degeneration (AMD): associations with cardiovascular disease phenotypes and lipid factors, Dec 22, 2016.
