Bausch + Lomb and Clearside Biomedical Announce the U.S. Commercial Launch of XIPERE® For Suprachoroidal Use for the Treatment of Macular Edema Associated with Uveitis

XIPERE ^® is the First and Only FDA-Approved Therapy for Delivery via Suprachoroidal Injection

Bausch + Lomb, a leading global eye health business of Bausch Health Companies Inc. (NYSETSX: 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 the U.S. commercial launch of XIPERE ® (triamcinolone acetonide injectable suspension), the first and only therapy approved by the U.S. Food and Drug Administration (FDA) for suprachoroidal use for the treatment of macular edema associated with uveitis, a form of eye inflammation. 1

"XIPERE ^® is the first and only therapy available in the United States that utilizes the suprachoroidal space to treat patients who struggle with macular edema associated with uveitis, which is the leading cause of vision loss in people with uveitis ² ," said Joseph C. Papa , chairman and CEO, Bausch Health . "Throughout the past several months, we have been training eye care professionals all over the country on how to properly administer XIPERE ^® using its unique suprachoroidal injection method, which enables targeted delivery and compartmentalization of the medication. We are pleased that XIPERE ^® is now broadly available as a new and unique treatment option for the 300,000 Americans who suffer from this serious condition. ³ "

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 loss. ⁴ XIPERE ^® is approved for the treatment of macular edema associated with uveitis via suprachoroidal administration using the proprietary SCS Microinjector ^® developed by Clearside.

"The commercialization of XIPERE ^® is an exciting step forward for the treatment of macular edema associated with uveitis, and also for increasing education and recognition of the suprachroidal space as a highly effective administration route for back-of-the-eye therapies," said George Lasezkay, Pharm.D., J.D., president and CEO, Clearside. "As the first commercial product developed by Clearside and the first therapy approved for macular edema associated with uveitis, XIPERE ^® represents our commitment to delivering much needed treatments for those living with serious retinal diseases."

Suprachoroidal administration is an innovative approach for delivering ocular therapies that may facilitate more targeted delivery of therapeutic agents to the retina and choroid. The suprachoroidal space is located between the sclera and the choroid, which expands upon injection, allowing delivery of XIPERE ^® to the posterior structures of the eye. ⁵

"Suprachoroidal administration, which provides exceptional access and high bioavailability to the posterior segment of the eye, has been well tolerated by patients," 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 pivotal study. "This administration technique is unlike traditional intraocular administration, and therefore, training for how to properly inject patients with this new medicine is important. I encourage eye care professionals to take advantage of the trainings being offered by Bausch + Lomb."

IMPORTANT SAFETY INFORMATION

• Your eye doctor will monitor you for elevated eye pressure following treatment and manage it with medication or surgery if required.
• See your eye doctor right away if your eyes become red, sensitive to light or painful, or if you notice changes in vision.
• XIPERE is not appropriate for use in patients with eye infections. It should be used with caution in patients with a history of herpes simplex in the eye.
• XIPERE is not appropriate for use in patients with a known allergy to triamcinolone acetonide or any other components of this product.
• Use of corticosteroids such as XIPERE may produce cataracts, increased eye pressure and glaucoma, and may increase the likelihood of eye infections.
• Patients being treated with XIPERE for extended periods of time will be monitored for problems with the body's hormonal system, which controls the ability to respond to stress.
• In clinical studies, the most common eye-related side effects were increased eye pressure and eye pain. Other side effects included cataract, floaters or flashes of light, injection site pain, burst blood vessels, reduced or blurred vision, dry eye, light sensitivity, redness, infection, swelling, watery eyes, eye or eyelid irritation, bumps on the eyelid, itchy eyes, and drooping eyelid.
  
  The most common non-eye-related side effect was headache.
