> "It takes about 10-15 years to develop one new medicine from the time it is discovered to when it is available for treating patients. The average cost to research and develop each successful drug is estimated to be $800 million to $1 billion. This number includes the cost of the thousands of failures: For every 5,000-10,000 compounds that enter the research and development (R&D) pipeline, ultimately only one receives approval."
