Clearside Biomedical Announces First Quarter 2022
Financial Results and Provides Corporate Update

- First Approved Suprachoroidal Product, XIPERE®, Now Commercially Available in U.S. -

- Cohort 4 Enrolling at 1.0 mg Dose in CLS-AX OASIS Wet AMD Phase 1/2a Trial -


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


ALPHARETTA, Ga., May 11, 2022 -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS®), today reported financial results for the first quarter ended March 31, 2022 and provided a corporate update.


“The approval and recent commercial launch of XIPERE® in the U.S. validates delivery into the suprachoroidal space by our proprietary SCS Microinjector®, and supports our strategic approach focused on small molecule suspensions,” said George Lasezkay, Pharm.D., J.D., Clearside’s President and Chief Executive Officer. “As part of the launch process, hundreds of retinal specialists throughout the country have been trained on the use of our SCS Microinjector. This vast experience and technical knowledge using our Microinjector establishes a strong base for our platform as we expand our internal and externally partnered therapeutic candidates.”


Dr. Lasezkay continued, “Our lead internal suprachoroidal pipeline product candidate, CLS-AX, combines our proprietary small molecule suspension of the tyrosine kinase inhibitor axitinib with delivery by our SCS Microinjector. We are progressing OASIS, our Phase 1/2a single dose escalating clinical trial targeting patients with wet AMD. We are encouraged by the growing interest in this trial, and as a result, we have recently doubled the number of clinical trial sites to ten. Our Safety Monitoring Committee reviewed one-month initial safety data from Cohort 3 and we are pleased to report that there were no dose limiting toxicities observed at the 0.5 mg dose. As a result, we are now enrolling patients in Cohort 4 at the higher dose of 1.0 mg while simultaneously continuing our Cohort 3 enrollment. We are targeting up to 25 patients in total from all four OASIS cohorts.”


“This expanded enrollment of Cohort 3 and the addition of Cohort 4 will allow us to collect more CLS-AX patient data in order to help guide our selection of the most appropriate dosing



protocol for our planned Phase 2b clinical trial. We now expect to report safety and tolerability data from both Cohorts 3 and 4 in the fourth quarter of this year. This will allow us to report a more comprehensive set of patient data as we will be able to include the complete analysis from all four dosing cohorts of the OASIS trial, in addition to the detailed individual patient data from the final two cohorts,” concluded Dr. Lasezkay.


Key Highlights

XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use for the treatment of macular edema associated with uveitis was commercially launched for sale in the U.S. by Bausch + Lomb.
Continued progress made in OASIS, Clearside’s U.S. based, open-label, dose-escalation Phase 1/2a trial in patients with wet AMD, to assess the safety and tolerability of CLS-AX (axitinib injectable suspension) administered by suprachoroidal injection via Clearside’s SCS Microinjector.
Benjamin R. Yerxa, Ph.D., Chief Executive Officer of the Foundation Fighting Blindness, the world’s leading private funding source for retinal degenerative disease research, was appointed to Clearside’s Board of Directors.
Multiple presentations and panels featuring the use of Clearside’s proprietary suprachoroidal space injection platform were highlighted at global conferences, including Association for Research in Vision and Ophthalmology (ARVO) 2022 Annual Meeting, the American Society of Cataract and Refractive Surgery (ASCRS) Meeting, Vit Buckle Society Annual Meeting, Sonoma Eye Meeting, Wet AMD & DME Drug Development Summit and Angiogenesis, Exudation, and Degeneration Virtual Conference.
Several posters were presented at ARVO related to XIPERE® for suprachoroidal use.
Two presentations were delivered on REGENXBIO asset RGX-314 administered via Clearside’s SCS Microinjector at ARVO.


First Quarter 2022 Financial Results


Clearside’s license and other revenue for the first quarter of 2022 was $347,000, compared to $34,000 for the first quarter of 2021.


Research and development expenses for the first quarter of 2022 were $4.5 million, compared to $5.5 million for the first quarter of 2021. The $1.0 million decrease was primarily attributable to reduced XIPERE-related expenses which offset CLS-AX Phase 1/2a clinical trial costs.


General and administrative expenses for the first quarter of 2022 were $3.5 million, compared to $2.9 million for the first quarter of 2021. The $0.6 million increase was primarily attributable to share-based compensation and higher salary costs.




Net loss for the first quarter of 2022 was $7.6 million, or $0.13 per share of common stock, compared to a net loss of $7.4 million, or $0.13 per share of common stock, for the first quarter of 2021.


As of March 31, 2022, Clearside’s cash and cash equivalents totaled $34.4 million. The Company believes it will have sufficient resources to fund its planned operations for at least the next twelve months.
