In early phase development, important questions are asked and the answers required are more complex than a simple yes or no. Because a drug appears to be effective for one person doesn’t mean it will be as effective in another person. What are the range of effects and side effects? What is the optimal dosage? What are the indications and contraindications? These are difficult questions, and getting the right answers requires extraordinary skills and resources.
