ALPHARETTA, Ga., Aug. 12, 2024 (GLOBE NEWSWIRE) -- 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 second quarter ended June 30, 2024, and provided a corporate update.
“Our Phase 2b ODYSSEY clinical trial utilizing CLS-AX (axitinib injectable suspension) in patients with wet AMD continues to advance on track and on time with topline data expected in late Q3 2024,” said George Lasezkay, PharmD, JD, President and Chief Executive Officer. “In July, the Safety Review Committee reviewed masked safety data and noted that there have been no drug-related Serious Adverse Events (SAEs), including no endophthalmitis or retinal vasculitis, and recommended the trial continue as planned without modifying the protocol. Both arms of the ODYSSEY trial have completed six months of treatment, with CLS-AX being re-dosed per protocol in the CLS-AX arm. Re-dosing with CLS-AX is an important and differentiating feature of the ODYSSEY trial, and the re-dosing data will be valuable as we evaluate the effects of CLS-AX in this chronic disease and plan our Phase 3 clinical development program.”
Dr. Lasezkay continued, “Several noteworthy events have also occurred featuring our commercial product, XIPERE®1, for the treatment of patients with macular edema associated with uveitis. Most importantly, our Asia-Pacific partner, Arctic Vision, reported positive results from their Phase 3 trial for XIPERE, known as ARCATUS in China, and announced that new drug applications (NDAs) for ARCATUS have been accepted for review in Australia and Singapore. In addition, data presented on the real-world use of XIPERE in the United States has shown the product has excellent durability as 87.7% of eyes did not require an injected or implanted corticosteroid for 6 months after a single dose of XIPERE2.”
“In May 2024, consensus guidelines for drug delivery by suprachoroidal administration, co-authored by 16 practicing retinal physicians, were published in the prominent journal, RETINA®. The article describes the physicians’ best practices for injection into the suprachoroidal space. These valuable guidelines, combined with our progress with CLS-AX and the promising real-world and Phase 3 data from XIPERE continue to demonstrate the advantages of suprachoroidal administration utilizing our proprietary SCS Microinjector® to deliver therapies to the back of the eye for the treatment of a variety of retinal diseases,” concluded, Dr. Lasezkay,

Second Quarter 2024 Financial Results
- License and other revenue for the second quarter of 2024 was $90,000, compared to $1.0 million for the second quarter of 2023. The revenue primarily related to payments pursuant to Clearside’s license agreements and revenue for services and the sales of SCS Microinjector kits to licensees.
- Research and development expenses for the second quarter of 2024 were $4.6 million, compared to $4.9 million for the second quarter of 2023. The decrease was primarily related to the CLS-AX program ($0.2 million), development of the SCS Microinjector ($0.2 million), and preclinical work ($0.1 million). This was partially offset by a $0.2 million increase in employee related costs.
- General and administrative expenses remained constant at $3.1 million in the second quarter of 2024 and 2023.
- Interest income for the second quarter of 2024 was $0.4 million compared to $0.5 million for the second quarter of 2023. The decrease was due to the lower balance of cash, cash equivalents and short-term investments.
- Other income for the second quarter of 2024 was $1.9 million, compared to $0 for the second quarter of 2023. Other income for the second quarter of 2024 was due to the change in fair value of the warrant liabilities from the prior March 31, 2024 valuation date.
- Non-cash interest expense remained constant at $2.3 million in the second quarter of 2024 and 2023. Non-cash interest expense was comprised of imputed interest on the liability related to the sales of future royalties and the amortization of the associated issuance costs.
- Net loss for the second quarter of 2024 was $7.6 million, or $0.10 per share of common stock, compared to net loss of $9.1 million, or $0.15 per share of common stock, for the second quarter of 2023.
- As of June 30, 2024, Clearside’s cash, cash equivalents and short-term investments totaled $29.4 million. The Company believes it will have sufficient resources to fund its planned operations into the third quarter of 2025.
