Transformative Medicines for Patients in Need

There are millions of people living with a condition that a CRISPR-based medicine has the potential to address.

For us, the patient is—and must be—at the center of everything we do. That is why we’ve partnered with leading patient groups and other organizations to help us on this critically important journey.

The Editas Medicine Commitment

Engage regularly – seek out opportunities to learn from the communities we aim to create a treatment option for, and continue to bring their voices into decision making and drug development planning.

Listen actively – health and treatment is deeply personal, and there are similarities and differences across diseases, and among individuals affected by the same disease. It is critical that we listen and understand diverse perspectives.

Engage authentically – we are optimistic about the promise of gene editing, yet there is still much to be learned. Through transparent communication about Editas Medicine and our approach to developing medicines we hope to ensure the expectations we set are realistic.
