Summary

Join us for an insightful webinar exploring how Quantitative Systems Pharmacology (QSP) and digital twins are reshaping clinical development strategies in rare diseases. With patient populations often too small for traditional trial designs, digital twin modeling presents a transformative approach to improve therapeutic development and regulatory interactions. Our partners from Sanofi will showcase real-world applications, including case studies in ASMD and Pompe disease, highlighting how QSP-based digital twins can address unique challenges in rare disease trials and gene therapies. Whether you’re a translational scientist, clinical developer, or regulatory strategist, this session will equip you with practical insights into cutting-edge modeling approaches for rare disease drug development.

Learning Objectives

By attending this webinar, participants will:

  1. Understand the role and value of QSP in clinical development for rare diseases.
  2. Learn how digital twin models are developed and used to support therapeutic decisions.
  3. Explore real-world case studies demonstrating regulatory applications of QSP-based digital twins.
  4. Identify challenges and opportunities in applying these models to rare disease and gene therapy trials.
