Clearside Biomedical Opens Enrollment in ODYSSEY Phase 2b Clinical Trial of CLS-AX (axitinib injectable suspension) in Wet AMD
- U.S. Clinical Sites Screening Treatment-Experienced Participants with Wet AMD -
- ODYSSEY Topline Results Expected in Q3 2024 -
ALPHARETTA, Ga., June 01, 2023 (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 enrollment has opened in ODYSSEY, its Phase 2b clinical trial of CLS-AX (axitinib injectable suspension) using suprachoroidal delivery in neovascular age-related macular degeneration (wet AMD).
“With the ODYSSEY clinical trial now open for enrollment, we are excited to continue exploring the potential of CLS-AX to provide an effective and less burdensome treatment option in the multi-billion-dollar wet AMD market,” said George Lasezkay, Pharm.D., J.D., Clearside’s President and Chief Executive Officer. “CLS-AX will be delivered via our patented SCS® Microinjector giving us unprecedented access to the back of the eye to directly target the site of the disease behind the visual field. We believe that our potent and well-tolerated tyrosine kinase inhibitor (TKI) combined with targeted suprachoroidal delivery has the potential to produce promising results in our Phase 2 clinical trial.”
“Our primary goals for ODYSSEY are to maintain visual acuity and demonstrate improved duration with reduced treatment burden for the CLS-AX arm. We believe that the number of participants, duration, and outcome measures of the study will provide the necessary clinical data to design a CLS-AX Phase 3 program. We are targeting a total of 30 U.S. based clinical trial sites for ODYSSEY and expect to report topline data from the trial in the third quarter of next year,” concluded Dr. Lasezkay.
About the ODYSSEY Phase 2b Clinical Trial
ODYSSEY is a randomized, double-masked, parallel-group, active-controlled, multi-center, Phase 2b clinical trial of 36 weeks duration.
About CLS-AX (axitinib injectable suspension)
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 preclinical studies in multiple species and in a Phase 1/2a wet AMD clinical trial in which CLS-AX was well tolerated and demonstrated an excellent safety profile. With suprachoroidal administration of axitinib, there is the potential to achieve prolonged duration and targeted delivery to affected tissue layers while limiting drug exposure to the front of the eye. Clearside is developing CLS-AX as a long-acting therapy for the treatment of retinal diseases.
About Age-Related Macular Degeneration (AMD)
Age-related macular degeneration causes a progressive loss of central vision and is the most common cause of legal blindness in individuals over age 55. Neovascular AMD (Wet AMD) is generally caused by abnormal blood vessels that leak fluid or blood into the macula, the part of the retina responsible for central vision, and accounts for the majority of vision loss in patients with this disorder. In the U.S., approximately 11 million patients are living with AMD1, and about 10% have the wet form2. Current treatments require life-long, frequent injections to maintain efficacy. This treatment regimen tends to cause a treatment burden for patients resulting in reduced compliance and under-treatment leading to potentially limited outcomes. In the U.S., the total economic impact of late-stage AMD is estimated to be approximately $49 billion, with the majority of costs attributed to lower productivity related to job loss or job reduction due to the condition3.
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 less than 1.2 millimeters, optimizing insertion and suprachoroidal administration of drugs.
About Clearside Biomedical, Inc.
Clearside Biomedical, Inc. is a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS®). Clearside’s SCS injection platform, utilizing the Company’s patented SCS Microinjector®, enables an in-office, repeatable, non-surgical procedure for the targeted and compartmentalized delivery of a wide variety of therapies to the macula, retina, or choroid to potentially preserve and improve vision in patients with sight-threatening eye diseases. Clearside is developing its own pipeline of small molecule product candidates for administration via its SCS Microinjector. The Company’s lead program, CLS-AX (axitinib injectable suspension), for the treatment of neovascular age-related macular degeneration (wet AMD), is in Phase 2 clinical testing. Clearside developed and gained approval for its first product, XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use, which is available in the U.S. through a commercial partner. Clearside also strategically partners its SCS injection platform with companies utilizing other ophthalmic therapeutic innovations. For more information, please visit www.clearsidebio.com.
