'The suprachoroidal space is an untapped frontier in eye health. We are proud to be the pioneers in treating serious retinal diseases by implementing this novel, targeted approach. With this approval, we begin a new era in delivering therapies to the back of the eye,' said George Lasezkay, Pharm.D., J.D., president and CEO, Clearside. 'XIPERE is the first commercial product developed by Clearside, the first product approved for injection into the suprachoroidal space and the first therapy approved for macular edema associated with uveitis. Our unique approach now has the potential to positively impact this patient population, which previously had no other treatment options approved for this indication.'
Macular edema is the buildup of fluid in the macula, which causes retinal swelling and distorted vision, and if left untreated, may lead to permanent vision loss3. XIPERE is designed to treat macular edema associated with uveitis via suprachoroidal administration using the proprietary SCS Microinjector developed by Clearside. Suprachoroidal administration is an innovative technique for delivering ocular therapies that may facilitate more targeted delivery of therapeutic agents to the retina and choroid.
The SCS Microinjector offers unique access to the back of the eye where sight-threatening disease often occurs. It is designed to provide targeted and compartmentalized delivery and higher proportions of absorption relative to intravitreal injection (IVT)4. Targeted drug delivery via the suprachoroidal space (SCS) may also limit corticosteroid exposure to the anterior segment5 with the potential to reduce the risk of certain adverse events, such as cataracts, intraocular pressure elevation and exacerbation of glaucoma, that are commonly associated with local delivery techniques6.
'The safety and efficacy data of XIPERE was demonstrated in multiple clinical studies and its unique suprachoroidal administration approach provides exceptional access and high bioavailability to the posterior segment of the eye,' said
XIPERE Clinical Data
The clinical program for XIPERE included the pivotal Phase 3 trial (PEACHTREE), a Phase 3, multi-center, non-interventional extension study (MAGNOLIA), and an open-label safety trial (AZALEA).
The FDA approval of XIPERE was based on results from PEACHTREE, a randomized, multicenter, double-masked, sham-controlled Phase 3 clinical trial of 160 patients with macular edema associated with uveitis. XIPERE is the first and only uveitic macular edema treatment to demonstrate clinical efficacy with a BCVA (Best Corrected Visual Acuity) primary endpoint.
The primary efficacy endpoint was the proportion of patients in whom BCVA had improved by at least 15 letters from baseline after 24 weeks of follow-up. In the trial, a statistically significantly greater proportion of patients treated with XIPERE (47%) achieved at least a 15-letter improvement in BCVA than patients in the control arm (16%, p< 0.01) at Week 247.
The most common adverse reactions reported by greater than or equal to 10% of patients and at a rate greater than control included elevated intraocular pressure and eye pain.
