CLSD

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 third quarter ended September 30, 2022 and provided a corporate update.

“Based on the encouraging data we reported today from our OASIS study, we are now positioned to advance our suprachoroidal CLS-AX program into a larger randomized, controlled Phase 2 trial,” said George Lasezkay, Pharm.D., J.D., Clearside’s President and Chief Executive Officer. “We see significant opportunity across the retinal disease spectrum for CLS-AX, which combines pan-VEGF inhibition from the highly potent tyrosine kinase inhibitor, axitinib, with targeted SCS delivery using our SCS Microinjector®. In addition, the growing level of awareness and acceptance of SCS delivery in the retinal medical community is further validating our SCS delivery platform, with recent positive clinical data presented from four other suprachoroidal trials of three different novel therapies each delivered with our proprietary SCS Microinjector.”

Key Highlights

• Reported favorable results of safety, durability and biologic effect observed in the higher doses administered in Cohorts 3 and 4 of OASIS, Clearside’s U.S. based, open-label, dose-escalation Phase 1/2a clinical trial of CLS-AX in patients with wet AMD.
• Entered into a Royalty Interest Purchase and Sale Agreement with HealthCare Royalty Partners, in which Clearside received an initial payment of $32.5 million, less certain expenses, with the potential to receive up to $65 million in non-dilutive funding to support ongoing clinical development of Clearside’s pipeline, and pursuant to which HealthCare Royalty Partners will receive certain royalties and milestone payments due to Clearside from XIPERE® (triamcinolone acetonide injectable suspension) and certain SCS Microinjector license agreements.
• Clearside’s commercialization partner, Bausch + Lomb, received XIPERE’s permanent J-code, a reimbursement code used in the U.S. by commercial insurers and government payers, which became effective for provider billing on July 1, 2022.
• XIPERE was nominated for the 2022 Prix Galien USA Award, which recognizes outstanding achievements in improving the global human condition through the development of innovative drugs, technologies, and other treatments.
• Clearside’s proprietary SCS delivery platform was highlighted in multiple presentations and panels at global conferences, including the American Academy of Ophthalmology (AAO) 2022 Annual Meeting, the Retina Society, the Ophthalmology Futures Retina Forum 2022, the American Society of Retina Specialists (ASRS) Annual Meeting, and the Ophthalmology Innovation Source (OIS) Retina Innovation Summit.

Third Quarter 2022 Financial Results

Clearside’s license and other revenue for the third quarter of 2022 was $0.3 million, compared to $3.1 million for the third quarter of 2021. This decrease was primarily attributable to higher revenue from partner licensing agreements in the third quarter of 2021.

Research and development expenses for the third quarter of 2022 were $4.6 million, compared to $5.1 million for the third quarter of 2021. This decrease was primarily attributable to a decrease in costs in the XIPERE program following approval in October 2021.

General and administrative expenses for the third quarter of 2022 were $2.4 million, compared to $2.8 million for the third quarter of 2021. This decrease was primarily attributable to a $0.3 million decrease in employee related costs related for share-based compensation.

Net loss for the third quarter of 2022 was $7.8 million, or $0.13 per share of common stock, compared to a net loss of $4.9 million, or $0.08 per share of common stock, for the third quarter of 2021. This decrease was primarily attributable to higher revenue from partner licensing agreements in the third quarter of 2021.

As of September 30, 2022, Clearside’s cash and cash equivalents totaled $53.4 million. The Company believes this cash balance will provide financial runway into 2024.
