This book is proposedto give an overview of the common issues facing rare disease drug developers, summarize challenges specific to clinical development in small populations, discuss drug development strategies in the evolving regulatory environment, explain generation and utilization of different data and evidenceinside and beyond clinical trials, and use recent examples to demonstrate these challenges and the development strategies that respond to the challenges.Key Features:* Rare disease.* Drug development.* Innovative clinical trial design.* Regulatory approval.* Real-world evidence.
