Hydrus Microstent Receives Highest Designation of Any MIGS Device as Part of AAO Treatment Guidelines

Ivantis’ Commitment to Scientific Rigor Earns Primary Open-Angle Glaucoma Preferred Practice Pattern Designation and Fifth Publication in the Journal Ophthalmology

IRVINE, Calif., Nov. 17, 2020 /PRNewswire/ -- Ivantis Inc., developer of the novel Hydrus® Microstent, a minimally invasive glaucoma surgery (MIGS) device intended to lower eye pressure for open-angle glaucoma patients, announced today that the American Academy of Ophthalmology (AAO) has designated the Hydrus Microstent as “Level 1, Moderate Quality, Strong Recommendation” — the highest designation of any MIGS device — in its 2020 Preferred Practice Pattern® treatment guidelines (PPP) released during this year’s annual meeting.

“It’s an honor for our Hydrus device to be given such an emphatic treatment recommendation by the AAO, the most respected organization in U.S. eye care,” said Dave Van Meter, president and CEO of Ivantis. “Since our inception over a decade ago, one of our guiding principles has been to become the leading evidence provider in the entire MIGS space. This recommendation reflects our commitment to clinical rigor driven by our passion to develop a best-in-class device that will help the millions of people suffering from glaucoma. We are thrilled to receive the highest designation of any MIGS device as part of the AAO’s treatment guidelines.”

AAO’s PPPs are evidence-based recommendations designed to identify characteristics and components of quality eye care as guidance for the pattern of best practice. Each PPP is valid for five years from the date of issue. Guidelines are developed by the academy’s H. Dunbar Hoskins Jr., MD Center for Quality Eye Care and are academy-approved without external financial support. The guidelines are externally reviewed by experts and stakeholders prior to publication.

“This marks an important and meaningful step in the validation of the entire MIGS category. Inclusion of Hydrus as a recommended procedure by AAO has confirmed what many of us in clinical practice already know, which is that MIGS is a vital part of our surgical armamentarium for managing glaucoma,” said Douglas Rhee, M.D., chairman of the Department of Ophthalmology at Case Western Reserve University Hospital. “There are only three recommended MIGS procedures, and the evidence for Hydrus was rated as the strongest. This is an important validation of the Hydrus device and its potential impact for our patients.”

Horizon Peer-Reviewed Publication and Four-Year Data Distinctions
Ivantis also announced today that the peer-reviewed journal Ophthalmology published the complete three-year results from the HORIZON pivotal trial. The study demonstrates that the Hydrus Microstent is the first and only MIGS device to show a statistically significant reduction in risk for invasive secondary surgeries. This is the fifth peer-reviewed article on the Hydrus Microstent to be published in the industry’s preeminent journal.

Dr. Nathan Radcliffe, a board-certified ophthalmologist from the New York Eye and Ear Infirmary, presented the latest HORIZON data earlier this week at the annual AAO meeting. His “4-Year Results from the HORIZON Trial” was selected as the best poster of the session.

Ivantis has the distinction of providing the first-ever four-year complete follow-up data for a MIGS device in a Food and Drug Administration (FDA) pivotal trial (twice the duration of any other MIGS company’s complete follow-up). The complete five-year follow-up data will be announced next spring.

The latest findings from the HORIZON study confirm the benefits of the Hydrus Microstent reported at three years in Ophthalmology and show that those benefits are maintained through four years, notably reducing the need for invasive secondary glaucoma surgery and medications to control glaucoma. These important benefits were observed without increased safety risk associated with Hydrus surgery. No other MIGS device has presented continuous outcome data from the complete study population in a pivotal trial beyond two years.

The HORIZON study is the largest prospective, randomized, controlled trial conducted for a MIGS device and the first to have a global span. The study included 556 patients with mild to moderate glaucoma treated in 38 centers in nine countries in North America, Europe and Asia. The study was designed to demonstrate the safety and effectiveness of the Hydrus Microstent for lowering intraocular pressure (IOP) in glaucoma patients undergoing planned cataract surgery. Patients were randomized 2:1 to receive cataract surgery plus the Hydrus Microstent or cataract surgery alone. The two-year results of the trial provided the foundation for FDA approval of the Hydrus Microstent. Effectiveness outcomes exceeded those reported in any other MIGS pivotal trial, and the Hydrus Microstent was approved in the U.S. in August 2018.

Key Four-Year HORIZON Data Presented at AAO:

• 65% of Hydrus Microstent patients remained glaucoma medication-free, compared with 41% in the cataract surgery-only arm. This represents the highest margin of total medication elimination compared to the control group reported for any MIGS pivotal trial.
  
• Analysis shows that 2.1% of Hydrus Microstent patients required subsequent invasive glaucoma surgery, compared with 6% of the cataract surgery-only patients, which represents a clinically meaningful and statistically significant difference. This finding is consistent with the HORIZON three-year data, where, for the first time in a MIGS study, a statistically significant reduction in risk for invasive secondary surgery was shown.
  
• The overall safety profile of cataract surgery plus implantation of the Hydrus Microstent was similar to cataract surgery alone, including visual acuity and endothelial cell density loss (ECL) from two to three years, and from three to four years. Long-term complications were limited to focal peripheral anterior synechiae (13%, 4.3% obstructive, 8.7% non-obstructive).

About the Hydrus Microstent
Roughly the size of an eyelash, the Hydrus Microstent is a next-generation MIGS device designed to reduce eye pressure by reestablishing flow through Schlemm’s canal, the eye’s natural outflow pathway. When placed in the canal during minimally invasive microsurgery, the device restores the flow of fluid in the eye, using a tri-modal mechanism of action:

1. The Hydrus Microstent creates a bypass through the trabecular meshwork, allowing outflow of aqueous humor.
2. It then dilates and scaffolds Schlemm’s canal to augment outflow.
3. Its length spans 90 degrees of the canal to provide consistent access to fluid collector channels in the eye.

The Hydrus Microstent is one of the most rigorously researched and thoroughly studied MIGS devices, with more than 4,000 cases treated globally in controlled clinical studies and registries in patients with a wide range of disease severities.

INDICATIONS FOR USE:
The Hydrus Microstent is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure (IOP) in adult patients with mild to moderate primary open-angle glaucoma (POAG).

CONTRAINDICATIONS:
The Hydrus Microstent is contraindicated under the following circumstances or conditions: (1) In eyes with angle-closure glaucoma; and (2) In eyes with traumatic, malignant, uveitic or neovascular glaucoma, or discernible congenital anomalies of the anterior chamber (AC) angle.

WARNINGS
Clear media for adequate visualization is required. Conditions such as corneal haze, corneal opacity or other conditions may inhibit gonioscopic view of the intended implant location. Gonioscopy should be performed prior to surgery to exclude congenital anomalies of the angle, peripheral anterior synechiae (PAS), angle closure, rubeosis and any other angle abnormalities that could lead to improper placement of the stent and pose a hazard.

PRECAUTIONS
The surgeon should monitor the patient postoperatively for proper maintenance of intraocular pressure. The safety and effectiveness of the Hydrus Microstent has not been established as an alternative to the primary treatment of glaucoma with medications, in patients 21 years or younger, eyes with significant prior trauma, eyes with abnormal anterior segment, eyes with chronic inflammation, eyes with glaucoma associated with vascular disorders, eyes with preexisting pseudophakia, eyes with uveitic glaucoma, eyes with pseudoexfoliative or pigmentary glaucoma, eyes with other secondary open-angle glaucomas, eyes that have undergone prior incisional glaucoma surgery or cilioablative procedures, eyes that have undergone argon laser trabeculoplasty (ALT), eyes with unmedicated IOP < 22 mmHg or > 34 mmHg, eyes with medicated IOP > 31 mmHg, eyes requiring > 4 ocular hypotensive medications prior to surgery, in the setting of complicated cataract surgery with iatrogenic injury to the anterior or posterior segment, and when implantation is without concomitant cataract surgery with IOL implantation. The safety and effectiveness of the use of more than a single Hydrus Microstent has not been established.

ADVERSE EVENTS
Common postoperative adverse events reported in the randomized pivotal trial included partial or complete device obstruction (7.3%); worsening in visual field MD by > 2.5 dB compared with preoperative (4.3% vs. 5.3% for cataract surgery alone); device malposition (1.4%); and BCVA loss of ≥ 2 ETDRS lines ≥ three months (1.4% vs. 1.6% for cataract surgery alone).
