Summary
Oligonucleotide therapeutics are transforming drug development, but their complex pharmacology and regulatory landscape present unique challenges. Join Certara and Ionis Pharmaceutical experts as we explore a model-informed approach to accelerating oligonucleotide drug development.
In this webinar, we’ll cover:
- Essential foundations of oligonucleotide therapeutics – what they are, how they work, and why they matter
- Regulatory strategies for success from day one – ensuring alignment with evolving global expectations
- How model-informed drug development (MIDD) accelerates and de-risks oligonucleotide programs – smarter decisions through data-driven insights
