Bethesda, MarylandMonday, April 27, 2009, 08:00 Hrs  [IST]

Sucampo Pharmaceuticals, Inc., and R-Tech Ueno, Ltd. (RTU) announced that Sucampo Pharma Americas, Inc. (SPA), a wholly owned subsidiary of Sucampo Pharmaceuticals Inc., licensed from RTU the commercialization rights to Rescula (unoprostone isopropyl) in the United States and Canada, including all associated patents and other intellectual property. In addition, RTU will be the exclusive supplier of finished product to Sucampo. Rescula was approved by the US Food and Drug Administration (FDA) for the treatment of open-angle glaucoma and ocular hypertension in 2000. In addition to these approved indications, Sucampo management believes that Rescula has the potential to be a treatment for dry age-related macular degeneration (dry AMD). As a result, Sucampo plans to initiate a phase 2 clinical trial with Rescula for dry AMD in 2010. Ryuji Ueno, M.D., Ph.D., Ph.D., chairman and chief executive officer of Sucampo Pharmaceuticals, said, "We are very pleased to add Rescula to Sucampo's product portfolio, alongside Amitiza®. We look forward to re-launching Rescula for its currently approved indications and to developing it as a potential treatment for dry AMD. We believe Rescula will be an important and integral part of our product portfolio. Both Rescula and Amitiza are created from the prostone technology whose therapeutic potential I discovered in the 1980s and is also the basis for Sucampo's clinical and preclinical pipeline compounds. Rescula targets disorders caused by the aging process, which is consistent with the commercial focus of Sucampo and one of my abiding passions." Yukiko Miyake-Hashitera, president and chief executive officer of R-Tech Ueno Ltd., said, "I am very pleased with this agreement as it provides an opportunity for Rescula to significantly impact the quality of vision and quality of life of patients both in the US and Canada. I have the utmost confidence that the potential of Rescula will be fully maximized." Gayle Dolecek, P.D., M.P.H., senior vice president of research & development, Sucampo Pharmaceuticals, said, "Rescula's safety profile and novel mechanism of action are two of its product attributes that provide a rationale for new indications. Its existing FDA approval status and safety profile should facilitate entry into clinical trials for dry AMD patients. If those trials are successful, Rescula will provide us the opportunity to meet the unmet medical needs of a substantial patient population." Stanley G. Miele, senior vice president of sales & marketing, Sucampo Pharmaceuticals, said, "This agreement provides Sucampo's sales team with a second prostone product. As part of our future re-launch of Rescula, we will continue focusing on the Amitiza market segments we now serve, while establishing relationships and a collaborative approach with specialists who treat ocular disorders. This is a very nice fit for our commercial team." Under the terms of the agreement, Sucampo will hold the exclusive rights to commercialize Rescula in the US and Canada for the treatment of glaucoma and ocular hypertension. Sucampo also will have the right to develop Rescula for additional indications. Sucampo also will have the right of first refusal to commercialize in the US and Canada any additional indications for which Rescula is developed by RTU. RTU will be exclusively responsible for supply of Rescula to Sucampo for the US and Canada. Sucampo will make an upfront payment to RTU of $3.0 million and will be responsible for additional milestone payments based on the achievement of specified development and commercialization goals. Sucampo will be responsible for the development, regulatory, and commercialization activities and expenses for Rescula in the US and Canada. As of April 1, 2009, RTU held six per cent of the outstanding common stock of Sucampo Pharmaceuticals' outstanding shares. Dr. Ueno, chairman and chief executive officer of Sucampo Pharmaceuticals, Inc., and his wife, Dr. Sachiko Kuno directly and indirectly own a majority of the capital stock of RTU. Dr. Ueno and Dr. Kuno do not hold any management or board positions with RTU. Dr. Ueno and Dr. Kuno are both members of the board of directors of Sucampo Pharmaceuticals and together directly or indirectly hold a substantial majority of the common stock of Sucampo Pharmaceuticals. Rescula (unoprostone isopropyl) is a synthetic docosanoid that is administered topically as a liquid eye drop that activates the BK channels in cells within the retina. Sucampo management believes that this activation of BK channels lowers intraocular pressure (IOP) by increasing the outflow of aqueous humour. Clinical studies have shown that in patients with a mean baseline IOP of 23 mm Hg, unoprostone isopropyl lowers IOP by approximately 3 to 4 mm Hg throughout the day. In clinical and preclinical studies Rescula has: increased ocular blood flow to the optic nerve and in the choroid; maintained visual field; delayed retinal degeneration induced by rhodoposin by inhibiting apoptosis; inhibited topographic and blood changes in an ischemic optic nerve head; and lowered intraocular pressure. SPA believes that these clinical effects suggest that Rescula could potentially be effective in the treatment of other ocular diseases. Rescula received its first marketing approval in Japan in 1994 for the treatment of glaucoma and ocular hypertension. Sucampo markets Amitiza (lubiprostone) 24 mcg in the US for chronic idiopathic constipation in adults and Amitiza 8 mcg in the US to treat irritable bowel syndrome with constipation in adult women. Sucampo also is developing the drug for additional gastrointestinal disorders with large potential markets. Sucampo Pharmaceuticals, Inc. has three wholly owned subsidiaries: Sucampo Pharma Europe, Ltd., located in the UK; Sucampo Pharma, Ltd., located in Japan; and, Sucampo Pharma Americas, Inc., located in Maryland. R-Tech Ueno was founded in 1989 by Ryuji Ueno, M.D. Ph.D., Ph.D., and has been a pharmaceutical venture corporation focusing on research, development, manufacturing and sales promotion of prescription drugs mainly in the area of ophthalmic diseases.
