ALPHARETTA, Ga., Nov. 25, 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®), announced today that presentations highlighting Clearside’s suprachoroidal delivery technology and data on its pipeline programs were delivered in medical meetings in Asia, Europe and the United States.
Most prominently, Clearside’s progress was featured in multiple activities at the 17th Asia-Pacific Vitreo-Retina Society (APVRS) Congress that took place November 22-24, 2024 in Singapore. In addition, Clearside’s technology and recent ODYSSEY topline data results for CLS-AX in wet AMD were highlighted at the Ophthalmology Innovation Summit (OIS) event November 22-23, 2024 in San Diego, CA and will be presented at the upcoming FLORetina 12th International Congress on OCT and OCT Angiography in Florence, Italy being held December 5-8 2024.
“We were excited to make a significant impact at the APVRS Congress in Singapore with multiple presentations and activities featuring our topline ODYSSEY results, XIPERE® real-world data, and four posters on our suprachoroidal delivery platform,” said Victor Chong, M.D., MBA, Chief Medical Officer and EVP, Head of Research and Development.
Dr. Chong continued, “As our partner Arctic Vision continues to advance XIPERE towards potential approval in China, Australia, and Singapore, we have seen growing interest in our delivery approach from the medical community in the region. As a result, we hosted three separate sessions to provide demonstrations of our suprachoroidal injection procedure. These sessions enabled attendees to familiarize themselves with our SCS Microinjector® technology with hands-on testing while learning more about our novel delivery approach. We were pleased that each session reached maximum attendance capacity.”
“Concurrently with APVRS, our patent protected, proprietary suprachoroidal space (SCS®) injection treatment approach was also featured at the OIS Summit. With well over 10,000 injections performed to date with our SCS Microinjector, we were able to showcase our commercial, clinical and regulatory expertise to establish Clearside as the leader in delivery of a wide variety of therapeutic agents to the suprachoroidal space. We also look forward to extending the discussion of our progress and positive ODYSSEY results at the FLORetina Congress early next month. As we close out 2024, I am more energized than ever about our prospects heading into 2025,” concluded Dr. Chong.

About Clearside’s Suprachoroidal Space (SCS®) Injection Platform and SCS Microinjector®
Clearside’s patent protected, proprietary suprachoroidal space (SCS®) injection treatment approach offers unprecedented access to the back of the eye, where sight-threatening disease often occurs. The Company’s unique platform is inherently flexible and intended to work with established and new formulations of medications. Clearside’s patented SCS Microinjector® can deliver a wide variety of drug candidates into the suprachoroidal space, providing targeted delivery to potentially improve efficacy and compartmentalization of medication to reduce or eliminate toxic effects on non-diseased cells. The SCS Microinjector system comprises a syringe, a custom-designed hub, and two 30-gauge hollow microneedles of varying lengths, each approximately one millimeter, optimizing insertion and suprachoroidal administration of drugs.
About ODYSSEY Phase 2b Clinical Trial
ODYSSEY was a randomized, double-masked, parallel-group, active-controlled, multicenter, 36-week, Phase 2b clinical trial in participants with wet AMD previously treated with intravitreal anti-vascular endothelial growth factor (VEGF) standard of care therapy. A total of 60 participants were treated for 36 weeks and randomized to either CLS-AX (1 mg) or aflibercept (2 mg) with a 2:1 randomization schedule (40 participants in CLS-AX arm and 20 participants in aflibercept arm). CLS-AX was administered via suprachoroidal injection using Clearside’s SCS Microinjector, and aflibercept was administered via intravitreal injection. Participants in the trial were determined to have active disease with a median duration of wet AMD diagnosis of 9.9 months.
The ODYSSEY trial achieved its objectives, including primary outcomes in mean change from baseline in best corrected visual acuity and safety and tolerability of CLS-AX, and secondary outcomes in visual function and ocular anatomy, the need for supplemental treatment, and treatment burden as measured by total injections over the trial duration. CLS-AX demonstrated compelling intervention-free rates with 100% of CLS-AX participants not requiring any additional treatment up to 3 months, 90% up to 4 months, 81% up to 5 months, and 67% up to 6 months after the initial CLS-AX dose. In the CLS-AX group, the injection frequency was reduced by approximately 84% compared to the average monthly injections in the 24 weeks prior to screening.
About CLS-AX (axitinib injectable suspension)
Clearside is developing CLS-AX as a longer-acting therapy for the treatment of retinal diseases. CLS-AX (axitinib injectable suspension) is a proprietary suspension of axitinib for suprachoroidal injection. Axitinib is a tyrosine kinase inhibitor (TKI), currently approved as an oral tablet formulation to treat advanced renal cell carcinoma, that achieves pan-VEGF blockade, directly inhibiting VEGF receptors-1, -2, and -3 with high potency and specificity. Clearside believes this broad VEGF blockade may have efficacy advantages over existing retinal therapies by acting at a different level of the angiogenesis cascade and may benefit patients who sub-optimally respond to current, more narrowly focused anti-VEGF therapies. Suprachoroidal injection of this proprietary suspension of axitinib has demonstrated meaningful potential in Phase 1/2a and Phase 2b wet AMD clinical trials in which CLS-AX was well tolerated and demonstrated a positive safety profile. With suprachoroidal administration of axitinib, there is the potential to achieve prolonged duration and targeted delivery to affected tissue layers by compartmentalizing axitinib behind the retina, thereby limiting drug exposure to the front of the eye.
About XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use
XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use is a proprietary suspension of the corticosteroid triamcinolone acetonide for administration to the suprachoroidal space for the treatment of macular edema associated with uveitis. XIPERE is approved by the U.S. Food and Drug Administration and is commercially available in the United States. Bausch + Lomb, a leading global eye health company dedicated to helping people see better to live better, has the exclusive license for the commercialization and development of XIPERE in the U.S. and Canada. Arctic Vision, a specialty ophthalmology company based in China, has the exclusive license for the commercialization and development of XIPERE, which they refer to as Arcatus®, in Greater China, South Korea, Australia, New Zealand, India and the ASEAN Countries.
