ALPHARETTA, Ga., Dec. 19, 2018 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a biopharmaceutical company dedicated to developing treatments that restore and preserve vision for people with serious eye diseases, today announced that it has submitted a New Drug Application (“NDA”) for XIPERETM to the U.S. Food and Drug Administration (“FDA”) for the treatment of macular edema associated with uveitis.
The uveitis market is expected to grow by 2024 to nearly $550 million in the United States and over $1 billion globally. Uveitis is a set of ocular inflammatory conditions and is one of the leading causes of vision loss worldwide, 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.
If approved by the FDA, XIPERE would be the first therapy for macular edema associated with uveitis.
“Based on the data from PEACHTREE, our pivotal Phase 3 clinical trial, we believe that XIPERE has the potential to become a new paradigm in the treatment of uveitic macular edema,” said Daniel White, Chief Executive Officer and President of Clearside. “PEACHTREE was the first clinical trial to demonstrate significant improvement in vision for patients with macular edema associated with non-infectious uveitis, and that improvement was achieved across all anatomical locations of uveitis. In addition, signs of inflammation resolved in more than two-thirds of patients treated with XIPERE across three commonly used measures of inflammation in the eye: vitreous haze; anterior chamber cells and anterior chamber flare. We have an experienced commercial team preparing for the potential launch of XIPERE and we also plan to submit applications for regulatory approval in select markets outside of the U.S.”
XIPERE, Clearside’s first investigational treatment to reach NDA submission, is a proprietary suspension of the corticosteroid triamcinolone acetonide formulated for administration to the back of the eye via suprachoroidal injection into the space located between the choroid and the outer protective layer of the eye known as the sclera. Clearside’s proprietary suprachoroidal treatment approach is designed to enable rapid dispersion of medicine to the back of the eye, so that adequate medicine reaches and stays at the site of disease and has the potential to act longer, while minimizing harm to the surrounding healthy parts of the eye. This approach has potential to provide efficacy advantages and require fewer treatments.
PEACHTREE, a randomized, masked, sham-controlled Phase 3 trial, enrolled 160 patients with macular edema associated with non-infectious uveitis, and compared XIPERE dosed every 12 weeks to sham control.
The PEACHTREE trial met its primary endpoint, with 47% of patients in the XIPERE arm gaining at least 15 letters in best corrected visual acuity, as measured using the Early Treatment of Diabetic Retinopathy Study scale, from baseline at week 24, compared to 16% of patients in the sham control arm (p<.001). All key secondary and additional endpoints of the PEACHTREE trial were also achieved.
Clearside Biomedical, Inc. is a biopharmaceutical company dedicated to developing treatments that restore and preserve vision for people with serious eye diseases. Clearside’s proprietary suprachoroidal treatment approach offers unprecedented access to the back of the eye where sight-threatening disease often occurs.
