Excision BioTherapeutics is developing CRISPR-based therapies to cure viral infectious diseases and improve the lives of chronically ill patients.
Why Excision
A new answer to persistent disease.
Chronic viral infections can hide in plain sight. They ask patients to manage a lifelong burden while conventional medicines keep the virus suppressed, not gone.
01 / THE OPPORTUNITY
Move beyond suppression.
Our CRISPR-based platform is designed to find and excise integrated viral DNA—the source of persistence—so a patient’s biology can do what medicine has not yet made possible.

The platformOne precise idea.
One precise idea.
Many possible cures.
We are bringing together the specificity of CRISPR, the discipline of translational science and a deep respect for the people waiting for better options.
Remove the source.
Design editing systems to cut out the DNA that enables viral persistence.
Make room for health.
Translate durable viral control into meaningful, lived improvements for patients.
The next chapter
The future of viral care should be curative.
