These differences necessitate tailored approaches to clinical trial design, dosing regimens, and formulation development. This course provides a comprehensive overview of the key considerations in pediatric and geriatric drug development, covering regulatory guidelines, ethical principles, pharmacokinetic/pharmacodynamic (PK/PD) modeling, and age-appropriate outcome measures. Participants will explore the challenges of recruiting and retaining these vulnerable populations in clinical trials, as well as strategies for addressing formulation and adherence issues. The course combines theoretical knowledge with practical case studies and interactive workshops, enabling participants to develop effective strategies for navigating the complexities of pediatric and geriatric drug development. By the end of the program, participants will possess the knowledge and skills to accelerate the development of safe and effective medicines for children and older adults, ultimately improving their health outcomes and quality of life.
