About ARVN001

ARVN001 is a proprietary suspension of the corticosteroid triamcinolone acetonide formulated for administration to the suprachoroidal space that is being investigated for the treatment of macular edema associated with uveitis (UME). Clearside's patented technology is designed to deliver drug to the suprachoroidal space located between the choroid and the outer protective layer of the eye,known as the sclera. Suprachoroidal injection 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.

In March 2020,Arctic Vision acquired the exclusive license for the development and commercialization of XIPERE in Greater China and South Korea. ARVN001 is Arctic Vision's project code for the XIPERE asset. In December 2020,Arctic Vision obtained approval for its Investigational New Drug (IND) submission for a UME Phase III trial from the National Medical Products Administration (NMPA) in China.

The product is not yet approved in any jurisdiction. The U.S. NDA filing was accepted by the FDA in May 2021.

About Uveitic Macular Edema (UME)

Uveitis is a set of ocular inflammatory conditions and one of the major causes of visual morbidity. Macular edema is a common complication in patients with uveitis,which is characterized by a build-up of fluid in the macula,the area of the retina responsible for sharp,straight-ahead vision. UME 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 panuveitis.
