Total number of registered clinical studies worldwide since 2000 Clinical studies are an important part of drug development globally. The number of registered clinical trials has increased significantly in recent years. As of October 2019, there were about 318,901 thousand clinical studies registered globally. The number of clinical studies has increased significantly since there were just 2,119 registered in 2000. In general, clinical trials have grown more complex in recent years and remain vital for the research and development of new drugs and products.
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 have a hand in pharmaceutical research and development globally. It is projected that by 2024 Johnson & Johnson will have the largest research and development spending among pharmaceutical companies.

Clinical studies globally

Most clinical studies occurring globally are held in countries outside of the U.S.. Many clinical trials performed outside of 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 just 9.6 percent of drugs make it from phase I to approval.
