Research and development
Research and development are an important part of pharmaceutical companies and includes drug development and product development. Among all industry sectors, the pharmaceutical industry spends the largest percentage of their revenue on research and development. Many companies are active in pharmaceutical research and development globally. It is projected Swiss company Roche will remain one of the largest research and development spenders among pharmaceutical companies in the near future.
Clinical studies globally
Most clinical studies occurring globally are held in countries outside of the U.S. Many clinical trials performed outside the U.S. and EU are done so because it is often easier and cheaper to conduct trials in other locations. Success rates for clinical trials depend heavily on the stage of the trial and the drugs or products being developed. Recent data suggested that only around 29 percent of drugs make it from phase II to phase III.
