Our History
Our History
Ionis’ RNA-targeted technology translates genomic insights into potentially transformative medicines.1
Creators of Trailblazing Innovation
Creators of Trailblazing Innovation
Ionis created the foundational chemistry behind our RNA-targeted medicines and have invested time and resources toward further advancements of our platform technology.1-3
Advances that have come from our research include4-8:
Developing the chemistry that is used as the basis for commercialized RNA-targeted medicines
Optimizing administration techniques and creating chemical modifications designed to deliver RNA-targeted medicines to target tissues
Creating iterative screening and refining processes to identify RNA-targeted medicines for clinical settings
Pioneering mechanisms to modulate gene expression
The success of nusinersen, tofersen, and eplontersen – all Ionis-originated, FDA-approved medicines – are examples of our ability to potentially bring life-changing options to patients with neurologic diseases.1,9-12
Ionis continues to build upon its pioneering platform and foundational knowledge to develop medicines that can alter disease trajectory.1,7,9,13
