Leading brands under threat

Ophthalmology encompasses some lucrative markets, but the future of leading brands in AMD is under threat, and while established markets like glaucoma and conjunctivitis have many therapeutic options, diabetic retinopathy remains largely untapped. Key opinion leaders agree there is unmet need in terms of drug delivery methods and dose frequency across ophthalmology diseases.

Highlights

The future of leading brands Lucentis (ranibizumab) and Xalatan (latanoprost) is at risk. Lucentis dominates AMD with 91% market share but the use of currently off-label Avastin (bevacizumab, Roche) is a threat. Xalatan, the gold standard in glaucoma achieved $1.5 billion in 2008 but the drug faces generic erosion after patent expiry in 2011

Diabetic retinopathy and AMD markets show high growth potential. Both diseases are highly prevalent, with 11.5 million cases of diabetic retinopathy, and 7.5 million in AMD, in the seven major markets in 2010. There are few drug treatments for AMD, while no approved drugs for diabetic retinopathy mean this market is untapped.

Key opinion leaders report high unmet need for reduced dosing regimens of existing therapies and an improvement in drug delivery methods. However, any new formulations of existing drugs will have to compete with cheap generics and need to show significant additional benefits.

Alcon Terminates the Development of Anecortave Acetate in Age-Related Macular Degeneration

HUENENBERG, Switzerland -- Alcon, Inc. (NYSE:ACL) announced today it has terminated the development program designed to evaluate the benefit of anecortave acetate treatment on the risk for developing sight-threatening choroidal neovascularization secondary to age-related macular degeneration. The decision followed a planned interim analysis of studies C-02-60 A and B that was performed after 2,546 patients had completed the 24 month time point. In this analysis, anecortave acetate showed no effect on the primary or secondary endpoints. In addition to terminating studies C-02-60 A and B, the company also terminated two smaller studies with an identical design that were being conducted in Asia, C-04-30 and C-05-34.

The company continues to study anecortave acetate administered as an anterior juxtascleral depot to reduce intraocular pressure in patients with open-angle glaucoma.

Artificial Retina offers new Hope

TUCSON - There is new hope for millions of people losing their vision. Many are going blind because of age-related macular degeneration and other conditions. But a new device called Artificial Retina has people seeing and believing.

Dean Lloyd is one of 14 people in the United States seeing through an Artifical Retina. He lost his vision in 1974. Lloyd says, "I almost lost all my vision in six months." Then in 2007, after a three hour operation, his sight, though limited, returned. "The beauty of the human brain is when you've had sight at one time, the brain seems to save the images," he said.

The camera on Dean's glasses captures an image and sends it wirelessly to an implant in his eye that stimulates his optic nerve to create an image in his brain. The next generation for Dean's implant is one that could help him see details and faces.

Satinderpall Pannu heads the Artificial Retina project at Lawrence Livermore labs in California. Starting with a silicon wafer and a thin coating of polymer, the disk is processed, electrodes are added and the implant is encased in titanium and gold, "It's a very rewarding feeling. It's amazing to me that technology that we've developed here at the lab can actually restore someone's sight," Pannu said.

Pannu says in 10 years, 50 million people in the world will suffer from blindness that these implants could reverse, "We really would like to take this tech to have a digital camera embedded in your retina and be able to restore your vision completely."

The only clinical trials for the artificial retina in the U.S. are run through a California Company "Second Sight."

Project leaders at Lawrence Livermore say they only have funding through next year. Right now, they're trying to lobby congress to extend the project's 8-million dollar a year budget, to improve the implant.

Miniature Telescope for Eye Approved for Macular Degeneration

TUESDAY, July 6 (HealthDay News) -- A tiny telescope that's implanted in an eye affected by advanced age-related macular degeneration (AMD) has been approved by the U.S. Food and Drug Administration.
The Implantable Miniature Telescope replaces the natural lens and magnifies an image more than two times, the FDA said in a news release.
The device is meant for people aged 75 and older who have blind spots associated with end-stage AMD. Candidates will be trained with an external telescopic device to see if they may benefit from the implanted product, the agency said.
AMD damages the eye's macula, causing vision loss in the center of the visual field. The condition affects mostly older people, often making it impossible to recognize faces or perform tasks such as watching television, the FDA said. Some 8 million Americans have been diagnosed with the condition, and about 25 percent of those are significantly visually impaired.
The FDA said it's requiring the labeling to warn that the device puts users at greater risk of injury to the eye's cornea.
As a condition of approval, California-based VisionCare Ophthalmic Technologies will conduct two follow-up studies of the device, the agency said.
