Clearside Biomedical Receives Notification of FDA Acceptance of NDA Filing for XIPERE™ (triamcinolone acetonide ophthalmic suspension) for Suprachoroidal Injection with PDUFA Date Set for October 19, 2019
The PDUFA (Prescription Drug User Fee Act) goal date has been assigned for
“We are delighted with this positive news on our XIPERE NDA. If XIPERE is approved, Clearside will have the first therapy indicated for patients suffering from macular edema associated with uveitis,” said
The NDA filing is supported by data from the Phase 3, PEACHTREE clinical trial that demonstrated significant and clinically meaningful improvement in vision for patients with macular edema associated with non-infectious uveitis, and that improvement was achieved across all anatomical locations of uveitis. Also, in patients with active inflammation at baseline, resolution was achieved in more than two-thirds of those treated with XIPERE across three commonly used measures of inflammation: vitreous haze, anterior chamber cells and anterior chamber flare.
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 from baseline at week 24, compared to 16% of patients in the sham control arm (p<0.001), using standardized Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity testing. All key secondary and additional endpoints of the PEACHTREE trial were also achieved.
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.
XIPERE (triamcinolone acetonide ophthalmic suspension) for Suprachoroidal Injection formerly known as CLS-TA, is a proprietary suspension of the corticosteroid triamcinolone acetonide formulated for administration to the back of the eye via suprachoroidal injection for the treatment of macular edema associated with uveitis. 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, thus potentially providing advantageous and sustained efficacy with a favorable safety profile.
