Bausch + Lomb and Clearside Biomedical Announce FDA Approval of XIPERE™ (triamcinolone acetonide injectable suspension) for Suprachoroidal Use for the Treatment of Macular Edema Associated with Uveitis

XIPERE™ is the First and Only Medicine to be Approved in the United States for Delivery via Suprachoroidal Injection, a Method Designed to Facilitate Targeted Delivery of Therapeutic Agents to the Retina and Choroid

LAVAL, QC and ALPHARETTA, Ga., Oct. 25, 2021 /PRNewswire/ -- Bausch + Lomb, a leading global eye health business of Bausch Health Companies Inc. (NYSE/TSX: BHC) (“Bausch Health”), and Clearside Biomedical, Inc. (Nasdaq: CLSD) (“Clearside”), a biopharmaceutical company revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space (SCS^®), today announced that the U.S. Food and Drug Administration (FDA) has approved XIPERE™ (triamcinolone acetonide injectable suspension) for suprachoroidal use for the treatment of macular edema associated with uveitis, a form of eye inflammation¹.

“With this FDA approval, XIPERE™ is the first and only therapy available in the United States that utilizes the suprachoroidal space to treat patients suffering from macular edema associated with uveitis, which is the leading cause of vision loss in people with uveitis². The utilization of the suprachoroidal space provides targeted delivery and compartmentalization of medication,” said Joseph C. Papa, chairman and CEO, Bausch Health. “The approval of XIPERE™ exemplifies our commitment to bringing innovative new options to help patients improve their treatment journey. We expect to make XIPERE™ available during the first quarter of 2022.”

“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 Steven Yeh, M.D., professor of ophthalmology and director of retinal disease and uveitis, Stanley M. Truhlsen Eye Institute, University of Nebraska Medical Center, and principal investigator for the XIPERE™ Phase 3 (PEACHTREE) pivotal study. “With the approval of XIPERE™, eye care professionals now have a new and innovative treatment option for their patients with macular edema associated with uveitis.”

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.

Important Safety Information about XIPERE™

Indication
XIPERE^™ (triamcinolone acetonide injectable suspension) for suprachoroidal use is a corticosteroid indicated for the treatment of macular edema associated with uveitis.

IMPORTANT SAFETY INFORMATION
Patients should be monitored following injection for elevated intraocular pressure. See Dosage and Administration instructions in full Prescribing Information.

• XIPERE is contraindicated in patients with active or suspected ocular or periocular infections including most viral diseases of the cornea and conjunctiva, including active epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella, mycobacterial infections, and fungal diseases.
• XIPERE^™ is contraindicated in patients with known hypersensitivity to triamcinolone acetonide or any other components of this product.
• Use of corticosteroids may produce cataracts, increased intraocular pressure, and glaucoma. Use of corticosteroids may enhance the establishment of secondary ocular infections due to bacteria, fungi, or viruses, and should be used cautiously in patients with a history of ocular herpes simplex.
• Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing’s syndrome, and hyperglycemia can occur following administration of a corticosteroid. Monitor patients for these conditions with chronic use.

• In controlled studies, the most common ocular adverse reactions were increased ocular pressure, non-acute (14%), eye pain, non-acute (12%), cataract (7%); increased intraocular pressure, acute (6%), cataract (7%), vitreous detachment (5%), injection site pain (4%) conjunctival hemorrhage (4%), visual acuity reduced (4%), dry eye (3%), eye pain, acute (3%), photophobia (3%), and vitreous floaters (3%), and in 2% of patients: uveitis, conjunctival hyperaemia, punctate keratitis, conjunctival oedema, meibomianitis, anterior capsule contraction, chalazion, eye irritation, eye pruritus, eyelid ptosis, photopsia, and vision blurred.

  The most common non-ocular adverse event was headache (5%).

• Corticosteroids should be used during pregnancy or nursing only if the potential benefit justifies the potential risk to the fetus or nursing infant.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
