                                 Drugs

EDEN PRAIRIE, Minn. & WHITEHOUSE STATION, N.J.--(BUSINESS WIRE)--June 27, 2007--SurModics, Inc. (Nasdaq: SRDX) and Merck & Co., Inc. (NYSE: MRK) today announced a License and Research Collaboration Agreement to pursue the joint development and commercialization of the I-vation(TM) sustained drug delivery system with TA (triamcinolone acetonide) and other products that combine Merck proprietary drug compounds with the I-vation system for the treatment of serious retinal diseases.

Under the terms of the agreement, Merck will lead and fund development and commercialization activities for the SurModics innovative I-vation drug delivery platform in combination with triamcinolone acetonide and proprietary Merck compounds. SurModics will receive an up front licensing fee of $20 million and will be eligible to receive up to an additional $288 million in fees and development milestones associated with the successful product development and attainment of appropriate U.S. and EU regulatory approvals for these new combination products. In addition, Merck will reimburse SurModics for its development activities, and SurModics will be responsible for the manufacture and supply of clinical and commercial products. SurModics will also receive royalties on product sales.

"Today's announcement is an important milestone in the history of SurModics and marks the first license of our sustained drug delivery platforms in the ophthalmology market," said Bruce Barclay, President and CEO of SurModics. "Over the past three years, and as a result of the hard work by our employees, we have made tremendous strides evolving our business strategy and focusing on new market opportunities. We are now in a position to provide more components of the final product and better leverage our expertise in developing biomaterials, surface modification and drug delivery technologies to provide significant benefits to patients."

"We are very pleased to join forces with SurModics in the development of the I-vation sustained drug delivery system as a platform for delivering TA and Merck compounds to treat retinal disease," said Darryle D. Schoepp, Ph.D., Merck's Senior Vice President and Head of Neuroscience Research and Development. "I-vation's encouraging TA Phase I clinical trial results along with SurModics' depth of technologies and expertise in polymers for sustained drug delivery make SurModics a compelling and complementary development partner."

"Introducing new treatments for retinal diseases for which there are few therapeutic options supports Merck's focus on developing new medicines for unmet medical needs. This agreement adds to our strong existing franchise in glaucoma, and builds upon Merck's long history of innovative therapeutics in ophthalmics," added Schoepp.

About I-vation

The I-vation Intravitreal Implant is a drug delivery system capable of delivering a variety of drugs on a sustained release basis for well over a year, can be implanted in a minimally invasive procedure, and may be removed once the drug has been fully released. Currently, the majority of treatments being developed for AMD and DME require repeated injections into the eye, often with a suboptimal drug dosing profile. Replacing multiple injections with a single implant providing long-term, controlled drug release could represent a significant advance in therapeutic treatment, including improved patient compliance, reduced side effects and greater efficacy.

I-vation TA (a version of the I-vation implant formulated with the steroid triamcinolone acetonide) is being studied in a Phase I human clinical trial called STRIDE (Sustained Triamcinolone Release for Inhibition of Diabetic Macular Edema). The trial is assessing the safety and tolerability of the I-vation(TM) Intravitreal Implant with triamcinolone acetonide (TA) in patients with Diabetic Macular Edema (DME) under an Investigational New Drug application with the U.S. Food and Drug Administration. The nine month data from the study were presented in May 2007 at the Association for Research in Vision and Ophthalmology (ARVO) annual meeting in Fort Lauderdale, Florida.

The I-vation sustained drug delivery system can be used in combination with compounds to provide a longer and more sustained drug delivery. The platform nature of this technology facilitates the use of SurModics' many drug delivery polymer matrix technologies, including the Bravo(TM) polymer matrix, which is currently used on the Cypher(R) Sirolimus-Eluting Coronary stent from Cordis Corporation, a Johnson & Johnson company.
