Clearside Biomedical Announces First Quarter 2024 Financial Results and Provides Corporate Update

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, 2024, and provided a corporate update.

“As we near the midpoint of 2024, I am excited to highlight key aspects of our program and the steps we have taken to position Clearside for an important year,” said George Lasezkay, Pharm.D., J.D., Clearside’s President and Chief Executive Officer. “Our lead clinical program, CLS-AX (axitinib injectable suspension), is focused on the multi-billion-dollar market for wet AMD. Our target profile for CLS-AX is to maintain visual acuity without the need for retreatment for potentially up to 6 months. The data readout from our Phase 2b ODYSSEY clinical trial remains on track for the end of the third quarter of this year. Importantly, ODYSSEY is a 36-week study designed to re-dose patients with CLS-AX at 6 months, or earlier if needed. This will provide valuable data in a chronic disease for patients treated with more than one dose of CLS-AX as we begin planning our CLS-AX Phase 3 clinical development program.”

Dr. Lasezkay continued, “We have an outstanding team at Clearside that has been strategically expanded over the past several months. We added Dr. Victor Chong, a well-respected, board-certified retinal specialist, as our Chief Medical Officer. Victor’s extensive major pharmaceutical company experience, most recently at Johnson & Johnson, is extremely valuable as he spearheads our product development activities led by the upcoming ODYSSEY data analysis and the planning for our Phase 3 program. In addition, we appointed Tony Gibney, a seasoned biotechnology executive, to our Board of Directors. Tony has broad expertise in business strategy, collaborations, finance, and M&A, including recent and relevant ophthalmology experience at Iveric Bio. We look forward to their contributions as we advance our pipeline and continue our efforts to increase the adoption of suprachoroidal delivery.”

Key Highlights

• Topline data expected in the third quarter of 2024 from Phase 2b ODYSSEY clinical trial of CLS-AX using suprachoroidal delivery in neovascular age-related macular degeneration (wet AMD).
• Victor Chong, M.D., MBA joined Clearside in March 2024 as Chief Medical Officer. Dr. Chong has more than 25 years of experience advancing drug candidates through all stages of development, including serving as Vice President, Global Head of Retina DAS at Johnson & Johnson, and Global Head of Medicine, Retinal Health at Boehringer Ingelheim.
• Appointed Tony Gibney to Clearside’s Board of Directors in April 2024. Mr. Gibney is an experienced biotechnology executive and former investment banker who brings over 25 years of experience dedicated to advising biotechnology companies on business strategy, collaborations, financings, and mergers and acquisitions.
• Completed a registered direct offering in February 2024, which generated $15.0 million in gross proceeds to Clearside.
• On January 1, 2024, a new permanent Category 1 Current Procedural Terminology (CPT) code for XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use became available for physician use.
• Multiple data presentations on the use of Clearside’s suprachoroidal delivery platform were featured at prominent medical meetings, including the Association for Research in Vision and Ophthalmology (ARVO), the Macula Society and Hawaiian Eye and Retina.
  • Presentations included positive data on the extended treatment duration of XIPERE utilizing suprachoroidal delivery. Real-world data showed excellent durability in which more than 75% of eyes did not require retreatment for 6 months after a single dose of XIPERE, supporting Clearside’s approach to extended drug release and reduced treatment burden for patients by delivering drug directly to the back of the eye via the SCS Microinjector.

First Quarter 2024 Financial Results

• License and other revenue for the first quarter of 2024 was $230,000, compared to $4,000 for the first quarter of 2023.
• Research and development expenses for the first quarter of 2024 were $5.6 million, compared to $4.5 million for the first quarter of 2023. The increase was primarily due to ODYSSEY clinical trial expenses.

• Other expense for the first quarter of 2024 was $1.5 million, compared to $0 for the first quarter of 2023.

• Non-cash interest expense for the first quarter of 2024 was $2.4 million, compared to $2.2 million in the first quarter of 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.
