  • First and only eye medicine to treat sight-threatening, symptomatic vitreomacular adhesion affecting 15,000 Canadians each year

MISSISSAUGA, ON, Nov. 20, 2013 /CNW/ - Alcon, the global leader in eye care and a division of Novartis, announced today that JETREA® (ocriplasmin) solution for intravitreal injection is now available to Canadians who suffer from symptomatic vitreomacular adhesion.1,2 Vitreomacular adhesion, or VMA, is an age-related, progressive and sight-threatening condition. If left untreated, it can be responsible for retinal distortion, decreased visual acuity, and vision deterioration, with the potential to cause irreversible vision loss or blindness.3,4,5,6 It is estimated to affect up to 15,000 people in Canada each year.7  Health Canada approved JETREA® on August 13, 2013.

"Before JETREA®, the only option we had for treating VMA was surgical intervention," said David Chow, MD, Retina Specialist and Director of the Toronto Retina Institute. "Now with the availability of JETREA®, we have a non-surgical option that can be offered during the early stages of VMA, which can make a difference in terms of quality of life for people living with this condition."

JETREA® (ocriplasmin), a recombinant form of human protein (plasmin), works by targeting the protein fibers that cause the abnormal pull between the vitreous and the macula of the eye. By dissolving these proteins, JETREA® separates the vitreous from the macula, releasing the vitreomacular adhesion.2,8 This one-time intravitreal injection has been shown to successfully resolve VMA.1,2

The Phase III studies, published in the New England Journal of Medicine, showed that patients who were treated with JETREA® (ocriplasmin) successfully achieved resolution of VMA as compared to placebo at day 28.1 In the integrated Full Analysis Set, 26.5% of the patients treated with JETREA® achieved resolution of VMA at Day 28 (versus 10.1% with placebo [P<0.001]).1

Side effects observed in the Phase III studies of JETREA® (ocriplasmin) were consistent with the release of traction and intravitreal injections. The most common Adverse Drug Reactions were consistent with pharmacologic vitreolysis, such as vitreous floaters, photopsia, or were due to inflammation/irritation resulting from either the injection procedure and/or the drug. These were generally considered mild to moderate and were resolved without complications.1

"At the core of our corporate mission is to provide innovative products to improve the quality of life by helping people see better," said Alex Long, General Manager of Alcon Canada. "We are pleased to offer patients in Canada the first and only pharmacological treatment for this progressive eye disease."

Alcon acquired the rights to commercialize JETREA® injection outside the United States from the Belgian biopharmaceutical company, ThromboGenics, which retains the rights to commercialize the drug in the US. In October 2012, JETREA® intravitreal injection was approved in the US for the treatment of patients with symptomatic VMA. European approval for JETREA® (ocriplasmin) was granted in March 2013 for the treatment of vitreomacular traction (VMT), including when associated with macular hole equal to or smaller than 400 microns.

About VMA
As people get older, the vitreous (jelly-like material inside the eye that helps maintain the round shape) detaches naturally from the retina (the light-sensitive layer of tissue located at the back of the eyeball).13 This detachment is part of the natural aging process and is common over the age of 50.

However, sometimes the vitreous remains attached to some areas of the retina, particularly at the macula, which is the area of the retina responsible for central vision needed for everyday tasks, such as driving, reading and recognizing faces. This is known as vitreomacular adhesion (VMA).13

If left unresolved, these areas of VMA can exert a 'pulling force' on the macula, a condition referred to as vitreomacular traction (VMT). In some cases, the pulling due to VMT may eventually tear the macula, leading to the formation of a macular hole.2,13 Symptomatic VMA is a progressive condition that is often responsible for retinal distortion and deterioration in vision, and has the potential to cause irreversible damage or blindness.3,4,5,6
