**Clearside Biomedical Announces Fourth Quarter and Full Year 2022 <br>Financial Results and Provides Corporate Update**

<br> - Initiation of Phase 2b ODYSSEY Trial of CLS-AX in Wet AMD Expected in Q2 2023 -

- Medical Meeting Presentations Highlight Significant Potential of CLS-AX Based on Positive OASIS Phase 1/2a Safety Data, Durability, and Biologic Effect Over 6 Months -

- Continued Growth in Retinal Specialists Trained in Suprachoroidal Space (SCS<sup>®</sup>) Injection Procedure Using FDA-Approved XIPERE<sup>®</sup> -

- Management to Host Webcast and Conference Call Today at 4:30 P.M. ET -

ALPHARETTA, Ga., March 9, 2023 -- Clearside Biomedical, Inc. (Nasdaq: CLSD), a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS<sup>®</sup>), today reported financial results for the fourth quarter and year ended December 31, 2022 and provided a corporate update.

"Over the past year, we have reinforced Clearside's leadership position in the delivery of therapeutics into the suprachoroidal space through our in-office, repeatable, non-surgical procedure utilizing our proprietary SCS Microinjector<sup>®</sup>," said George Lasezkay, Pharm.D., J.D., Clearside's President and Chief Executive Officer. "With the launch of XIPERE<sup>®</sup> in the United States in 2022 by our partner, Bausch + Lomb, we believe there is increasing acceptance of treating serious retinal diseases through the SCS. Importantly, we also made excellent progress with our internal CLS-AX (axitinib injectable suspension) wet AMD clinical program."

Dr. Lasezkay continued, "The positive data from our OASIS Phase 1/2a clinical trial reinforces our belief that CLS-AX has the potential to reduce treatment burden in patients with wet AMD while maintaining stable visual acuity. CLS-AX was well tolerated and demonstrated an excellent safety profile across all timepoints and doses in the trial. Importantly, the full extension data showed promising durability, with 67% of participants going at least six months without additional treatment."

"Given this favorable CLS-AX Phase 1/2a data, as previously announced, we will conduct a randomized, controlled, double-masked, Phase 2b clinical trial, called ODYSSEY, in wet AMD participants. Based on the draft guidance on wet AMD drug development

------

released on February 24, 2023, by the U.S. Food & Drug Administration (FDA), we plan to adjust our trial design to use on-label aflibercept dosing in the comparator arm of ODYSSEY. We expect a seamless transition to this adjusted trial design and plan to open trial enrollment in the second quarter of 2023," concluded Dr. Lasezkay.

**Key Highlights**

• Favorable safety data, durability, and biologic effect were reported from OASIS, Clearside's U.S.-based, open-label, dose-escalation Phase 1/2a clinical trial of CLS-AX (axitinib injectable suspension) in patients with neovascular age-related macular degeneration (wet AMD).

• Clearside's XIPERE<sup>®</sup> (triamcinolone acetonide injectable suspension) commercialization partner, Bausch + Lomb, continues to expand outreach and training with over 1,000 retinal physicians trained to date in the use of the SCS Microinjector for suprachoroidal delivery.

• Clearside's licensing partner, Aura Biosciences, finalized its global Phase 3 clinical trial design in alignment with regulatory agencies and selected suprachoroidal route of administration to evaluate the efficacy and safety of belzupacap saratalocan (bel-sar) in early-stage choroidal melanoma, a life-threatening rare disease with no approved therapies.

• Former Chief Medical Officer and Chief Development Officer, Thomas A. Ciulla, M.D., M.B.A., transitioned to an external advisory role for Clearside as Chief Medical Advisor-Retina and Chair of the Scientific Advisory Board, continuing to share his medical expertise as a practicing retinal specialist and providing counsel on Clearside's suprachoroidal development programs.

• Promising data results were presented at major medical meetings on behalf of partners utilizing Clearside's proprietary SCS Microinjector to administer ocular gene therapy and oncology agents.

• Multiple presentations featuring Clearside's proprietary suprachoroidal space injection platform were highlighted at global conferences, including the Macula Society Annual Meeting; Angiogenesis, Exudation, and Degeneration Virtual Conference; American Academy of Ophthalmology; Retina Society Annual Scientific Meeting; and, OIS Retina Summit.

Clearside's license and other revenue for the fourth quarter of 2022 was $330,000, compared to $25.7 million for the fourth quarter of 2021. The $25.4 million decrease was primarily attributable to one-time milestone payments received from XIPERE licensing partners in the fourth quarter of 2021.

------

Clearside's license and other revenue for the year ended December 31, 2022, was $1.3 million, compared to $29.6 million for the year ended December 31, 2021. The $28.2 million decrease was primarily attributable to one-time milestone payments received from XIPERE licensing partners in 2021.
