Glaukos Announces Issuance of New U.S. Patent

SAN CLEMENTE, Calif.--()--Glaukos Corporation (NYSE: GKOS), an ophthalmic medical technology company focused on the development and commercialization of breakthrough products and procedures designed to transform the treatment of glaucoma, today announced that the United States Patent and Trademark Office has issued U.S. Patent No. 9,827,143 to the company.

“Shunt Device and Method for Treating Ocular Disorders”

Entitled “Shunt Device and Method for Treating Ocular Disorders”, the newly issued patent covers ocular devices and methods of surgically implanting the devices at least partially within Schlemm’s canal to facilitate the flow of aqueous humor.

“Our fundamental strategy at Glaukos is to develop innovative micro-scale technologies that provide viable new treatment options for people suffering with glaucoma, one of the world’s leading causes of blindness,” said Thomas Burns, president and chief executive officer. “This issued patent strengthens the protection of our inventions, further substantiates the proprietary nature of our technology and further expands our portfolio of more than 200 patents issued in the U.S. and major international markets.”

Glaukos pioneered Micro-Invasive Glaucoma Surgery (MIGS) and received U.S. Food and Drug Administration (FDA) approval for the iStent® Trabecular Micro-Bypass, the market’s flagship MIGS device, in June 2012. Inserted through the trabecular meshwork and into Schlemm’s canal, the iStent is designed to lower intraocular pressure (IOP) by restoring the natural, physiological outflow of aqueous humor in patients with open-angle glaucoma. The iStent is currently approved for use in the United States in conjunction with cataract surgery. Made of surgical-grade non-ferromagnetic titanium that is coated with heparin, the iStent is approximately 1.0 mm long and 0.33 mm wide. Glaukos believes it is the smallest medical device ever approved by the FDA.

Glaucoma is characterized by progressive, irreversible and largely asymptomatic vision loss caused by optic nerve damage. There is no cure for the disease and reducing IOP is the only proven treatment. Based on analysis of population-based surveys, medical claims data and other statistics, the company estimates that there are approximately 5.4 million people in the U.S. with primary open-angle glaucoma, the most common form of the disease.

About iStent Trabecular Micro-Bypass Stent (U.S.)

Indication for Use: The iStent Trabecular Micro-Bypass Stent is indicated for use in conjunction with cataract surgery for the reduction of IOP in adult patients with mild-to-moderate open-angle glaucoma currently treated with ocular hypotensive medication.

Contraindications: The iStent is contraindicated in eyes with primary or secondary angle closure glaucoma, including neovascular glaucoma, as well as in patients with retrobulbar tumor, thyroid eye disease, Sturge-Weber Syndrome or any other type of condition that may cause elevated episcleral venous pressure.

Warnings: Gonioscopy should be performed prior to surgery to exclude PAS, rubeosis, and other angle abnormalities or conditions that would prohibit adequate visualization of the angle that could lead to improper placement of the stent and pose a hazard. The iStent is MR-Conditional meaning that the device is safe for use in a specified MR environment under specified conditions, please see label for details.

Precautions: The surgeon should monitor the patient postoperatively for proper maintenance of intraocular pressure. The safety and effectiveness of the iStent has not been established as an alternative to the primary treatment of glaucoma with medications, in children, in eyes with significant prior trauma, chronic inflammation, or an abnormal anterior segment, in pseudophakic patients with glaucoma, in patients with pseudoexfoliative glaucoma, pigmentary, and uveitic glaucoma, in patients with unmedicated IOP less than 22 mmHg or greater than 36 mmHg after “washout” of medications, or in patients with prior glaucoma surgery of any type including argon laser trabeculoplasty, for implantation of more than a single stent, after complications during cataract surgery, and when implantation has been without concomitant cataract surgery with IOL implantation for visually significant cataract.

Adverse Events: The most common post-operative adverse events reported in the randomized pivotal trial included early post-operative corneal edema (8%), BCVA loss of ≥ 1 line at or after the 3 month visit (7%), posterior capsular opacification (6%), stent obstruction (4%) early post-operative anterior chamber cells (3%), and early post-operative corneal abrasion (3%). Please refer to Directions for Use for additional adverse event information.

Caution: Federal law restricts this device to sale by, or on the order of, a physician. Please reference the Directions for Use labeling for a complete list of contraindications, warnings, precautions, and adverse events.
