At Arbor, we envision a world free of disease by using genetic medicines to fundamentally shift the paradigm from treatment to functional cure, and ultimately to prevention. We aim to accomplish this through the discovery of programmable DNA editors with the power to enable bespoke curative genetic medicines for patients.
We believe gene editing therapeutics cannot be approached as “one size fits all” – as it is clear that each disease requires a unique approach to DNA editing. Guided by cutting-edge science and driven by a passion to deliver for patients, we have amassed one of the most talented and dedicated teams in the field to continue building upon the groundbreaking work of our founders.
The result is what we believe to be the most extensive toolbox of genomic editors in the industry to date, which has the PAM diversity to target more than 93% of the human genome—allowing us to begin with the underlying disease pathology and then choose an optimal editing approach for that disease. We believe this approach can yield important medicines and put cures within reach for patients with a wide range of genomic diseases.
