Ivantis Announces 3 Year Results of Australian SPECTRUM Registry for Hydrus Microstent
IRVINE, California, Nov. 8, 2019 /PRNewswire-AsiaNet/ --

--Largest Set of MIGS Data Ever Produced in Australia Includes Over 900 Eyes 
with 200+ Stand-Alone Glaucoma Procedures

Ivantis today announced long term results of the Australian cohort of the 
Global SPECTRUM registry. SPECTRUM is a post market patient registry for the 
Hydrus(R) Microstent, a microinvasive glaucoma surgery (MIGS) device to treat 
patients with open-angle glaucoma in conjunction with cataract surgery or as a 
stand-alone procedure outside the United States.

The SPECTRUM Registry was conceived in collaboration with leading Australian 
glaucoma specialists and comprehensive ophthalmologists. The study received 
initial ethics approval from the Royal Australia New Zealand College of 
Ophthalmologists (RANZCO) in 2014. Over 900 patients were recruited from 12 top 
eye surgery centers across Australia and New Zealand, making this the largest 
body of MIGS data produced from the region to date. SPECTRUM Australia includes 
a broad range of disease ranging from very mild glaucoma patients undergoing 
cataract surgery to stand-alone patients with moderate disease unresponsive to 
medical therapy to advanced cases requiring standalone Hydrus following 
unsuccessful conventional glaucoma surgery. Follow-up at 3 years was completed 
in 70% of eligible subjects.

The data will be presented at the Royal Australian & New Zealand College of 
Ophthalmologists Annual Scientific Congress in Sydney, Australia on November 9, 
2019 by Ashish Agar, MBBS, PhD. A glaucoma specialist from the Prince of Wales 
Hospital in Sydney, Dr. Agar was one of the first surgeons to use the Hydrus 
Microstent in Australia & New Zealand.  

Key findings at 3 years include:

    --  In patients undergoing combined cataract surgery and Hydrus placement, 
        mean IOP dropped over 20% with concurrent elimination of a full 
        medication 
    --  In patients undergoing standalone Hydrus placement, mean IOP dropped 
        roughly 30%, with concurrent elimination of a full medication (this 
        group had higher baseline pressures due to more severe disease) 
    --  Patients in the registry reached average intraocular pressures of 15 
        mmHg or less in both the combination cataract surgery and standalone 
        treatment groups 
    --  The results in both treatment groups were consistent at 1, 2, and 3 
        years, making the SPECTRUM Australia series the largest MIGS series 
        followed for 3 years

According to Dr. Agar, a contributor to SPECTRUM Australia, "It's an honor to 
see the effort put into the SPECTRUM registry follow up come to fruition with 
the release of this comprehensive and important data set dedicated to 
Australian and New Zealand glaucoma patients.  I have now used the Hydrus for 
over 5 years, and a few things about this data set stand out.  First, the 
device effect is remarkably consistent over time, which is critical when 
remembering that glaucoma is a long-term disease. Second, it is clear from the 
results of the combination and standalone groups that the device significantly 
lowers IOP with or without cataract surgery. This is especially important as 
standalone data has been crucial in our advocacy for this technology to be 
accessible to all patients, not just those with co-existing cataract. Finally, 
not only does this data mirror the robust published randomized trial results we 
have seen with Hydrus, but there is great consistency across all 12 sites in 
SPECTRUM, and that is reassuring on many levels.  I wish to congratulate 
Ivantis, and my fellow investigators for the commitment to this important 
initiative for our patients."

Dr. Brendan Cronin, Director of Education at the Queensland Eye Institute, and 
leading contributor to the registry, commented, "The Hydrus has become an 
invaluable addition to my practice since I added it 5 years ago. As a general 
ophthalmologist, typically treating milder disease in conjunction with cataract 
surgery, my goal is to safely eliminate medications for my patients.  I find 
the Hydrus excels in achieving this.  Our patients typically reflect the 
mildest end of the disease spectrum, and we found that over 80% of our patients 
remained medication free to 2 years and over 70% remain so at 3 years.  My 
referring optometrists have noticed a profound impact from Hydrus with their 
patients, and it's a privilege to now see this experience become a part of the 
broader 3 year SPECTRUM Australia presentation."

Ivantis was founded in 2007, and the Hydrus has been developed in part through 
investment support from GBS Ventures of Melbourne.

Dave Van Meter, President and CEO of Ivantis, remarked, "Ivantis has been built 
with a goal to provide the most robust data sets in the MIGS space to allow 
surgeons to make the most informed decisions for their patients.  We are 
thrilled to have endeavored on this major undertaking in partnership with key 
ophthalmology leadership in Australia and New Zealand.  We now look forward to 
ongoing commercialization in the region on the back of this important new data 
set dedicated to Australian and New Zealand patients and the surgeons who treat 
them."

About the Hydrus(R) Microstent
Roughly the size of an eyelash, the Hydrus(R) 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 into the 
trabecular meshwork and the canal during MIGS, the aqueous drainage device 
restores the flow of fluid in the eye using a Tri-Modal(TM) mechanism of 
action. First, it creates a bypass through the trabecular meshwork, allowing 
outflow of aqueous humor. It also dilates and scaffolds Schlemm's canal to 
augment outflow. Finally, with a length that spans 90 degrees of the canal, it 
provides consistent access to the fluid collector channels in the eye. 

The Hydrus(R) Microstent is one of the most rigorously researched and 
thoroughly studied of all MIGS devices, with more than 4,000 cases treated 
globally in patients with a wide range of disease severities in randomized 
trials or registries. 

About the SPECTRUM Global Registry
SPECTRUM is the world's largest single-device registry in ophthalmology, and 
completed enrollment in November 2019.  SPECTRUM is a patient registry for the 
Hydrus(R) Microstent, a microinvasive glaucoma surgery (MIGS) device to treat 
patients with mild to moderate primary open-angle glaucoma (POAG) in 
conjunction with cataract surgery or as a stand-alone procedure outside the 
United States.

The SPECTRUM Registry, initiated in 2013 in markets outside the U.S., covers 
the broadest range of glaucoma ever studied in a single body of data for a MIGS 
device and includes cases from 50 centers in 19 countries. It comprises nearly 
3,000 eyes and to date has over 70% follow-up. Of the procedures captured in 
the SPECTRUM Registry, over 700 were in stand-alone glaucoma cases -- the 
largest reported series of stand-alone glaucoma cases in MIGS. 

The entire body of SPECTRUM data will be presented in 2021, and certain early 
subsets will be shared throughout 2020 at various medical conferences.

INDICATIONS FOR USE: 
The Hydrus Microstent is indicated for the reduction of intraocular pressure 
(IOP) in adult patients with primary open-angle glaucoma (POAG) as a standalone 
treatment or in conjunction with cataract surgery.
