CLSD Clearside Biomedical Inc

Clearside Biomedical, Inc. (Nasdaq: CLSD) (“Clearside” or the “Company”), a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS®), reported that Arctic Vision’s New Drug Application (NDA) for ARCATUS® for the treatment of uveitic macular edema (UME) has been formally accepted for review by the Center for Drug Evaluation of China National Medical Products Administration. The NDA submission is supported by positive topline results from Arctic Vision’s Phase 3 UME clinical trial in China.

ARCATUS (known as XIPERE® in the U.S.) utilizes Clearside’s proprietary SCS Microinjector® and is the first and currently only approved suprachoroidal therapy to treat UME. It has already been approved by the Food and Drug Administration in the United States, Therapeutic Goods Administration in Australia, and the Health Sciences Authority in Singapore.

George Lasezkay, PharmD, JD, President and Chief Executive Officer of Clearside, commented, “Our partner, Arctic Vision, continues to make excellent progress in advancing our product in the Asia-Pacific region. The Chinese UME market is large, with several million uveitis patients1. As the first SCS® injection therapy, our product utilizes an innovative delivery platform that enables the rapid and adequate dispersion of medicine to the back of the eye, offering the potential for the medicine to act longer and minimize harm to the surrounding healthy parts of the eye.”

Arctic Vision is a China-based ophthalmic biotech company that has the exclusive license for the commercialization and development of XIPERE® (triamcinolone acetonide injectable suspension) for suprachoroidal use, which they refer to as ARCATUS® or ARVN001, in Greater China, South Korea, Australia, New Zealand, India and the ASEAN Countries.

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 global uveitis treatment market is projected to grow from approximately $2.3 billion in 2023 to $4.5 billion by 2032.2
