Clearside Biomedical’s Partner Arctic Vision Reports Positive Topline Results from Phase 3 Clinical Trial of ARCATUS® for Suprachoroidal Use in Uveitic Macular Edema Patients in China
Primary and Secondary Endpoints Achieved with Favorable Tolerability and Safety Profile
ALPHARETTA, Ga., July 29, 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 that its partner, Arctic Vision, reported positive topline results from its Phase 3 clinical trial of ARCATUS® (ARVN001) for the treatment of Uveitic Macular Edema (UME) in China. In addition, Arctic Vision announced that new drug applications (NDAs) for ARCATUS have been officially accepted in Australia and Singapore.
ARCATUS is Arctic Vision’s name for XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use which was originally developed by Clearside. Arctic Vision is a specialty ophthalmology company based in China that has the exclusive license for the commercialization and development of XIPERE® in Greater China, South Korea, Australia, New Zealand, India and the ASEAN Countries.
“This new, positive Phase 3 data from Arctic Vision reinforces the global product opportunity of XIPERE as a key treatment option for patients with uveitic macular edema,” said, George Lasezkay, Pharm.D., J.D., President and Chief Executive Officer. “XIPERE was our first FDA-approved product and has led the way for our proprietary suprachoroidal space (SCS®) injection treatment approach that offers unprecedented access to the back of the eye, where sight-threatening disease occurs. Our partner, Arctic Vision, is making excellent progress in bringing this important therapy to market in the Asia-Pacific region.”
Arctic Vision announced the following results from its Phase 3 trial. The trial met the primary endpoint and secondary endpoints and demonstrated significantly better visual acuity improvement and edema control in the treatment arm over the sham arm. In the study, 38.5% of ARVN001-treated patients gained 15 Early Treatment Diabetic Retinopathy Study (ETDRS) letters or more in vision vs 9.4% in the sham group. Central subfield thickness (CST) reduction was 204.3 microns in ARVN001-treated patients vs 1.6 microns in the sham group at week 24. Both reached statistical significance (p<0.001). Furthermore, the mean best corrected visual acuity (BCVA) gain was 9.6 letters at week 4 and 12.2 letters at week 24. Similarly, the CST changes achieved over 200 microns reduction at week 4 and maintained the reduction to week 24. There were no ocular serious adverse events (SAEs) or new safety signals reported.

About Uveitis and Macular Edema
Uveitis is a set of ocular inflammatory conditions and is one of the leading causes of vision loss, affecting approximately 350,000 patients in the United States and more than one million worldwide. Approximately one-third of these patients develop uveitic macular edema, a build-up of fluid in the macula, the area of the retina responsible for sharp, straight-ahead vision. Macular edema is the leading cause of vision loss and blindness in uveitis patients and can occur from uveitis affecting any anatomic location - anterior, intermediate, posterior or pan. The uveitis market is expected to grow by 2024 to nearly $550 million in the United States and over $1 billion globally.
