The business model is to: SELECT the most commercially attractive medical innovations; DEVELOP these to the stage where the greatest return on investment can be achieved; and COMMERCIALIZE the innovations through the sale of companies or out licensing of products. This will result in upfront payments, milestone payments and royalties. An exclusive deal flow agreement with Karolinska Institutet Innovations AB, along with other cooperation agreements with leading Nordic universities, delivers a continuous flow of innovations. Karolinska Development's flexible exit strategy enables projects to be exited at whichever stage of development offers the greatest return on investment, usually after Phase II clinical trials have indicated the desired pharmaceutical effect on patients - this being an important value enhancing step. Today, the portfolio consists of over 40 projects at various stages, from concept development to Phase II clinical trials, twelve projects are in clinical trials with six in Phase II. The portfolio is particularly strong in the areas of cancer, dermatology, inflammation, cardiovascular disease, women's health and diseases that affect the central nervous system. www.karolinskadevelopment.com Read Press Release as PDF: http://hugin.info/143071/R/1510325/445333.pdf This announcement is distributed by Thomson Reuters on behalf of Thomson Reuters clients.
