From concept to cure,
all in one place.
An early-stage biotechnology company bringing bioinformatics and gene editing together to investigate Crohn’s disease.
About ViroDyn
We investigate the biology behind disease to explore where new therapeutic possibilities could begin.
Our research focus
Crohn’s disease.
Early-stage researchViroDyn explores how genetic changes contribute to Crohn’s disease.
We bring bioinformatics and gene editing together to investigate those changes in the laboratory, asking whether correcting them can improve disease-relevant biology.
Use genetic and biological data to identify questions worth testing.
Use gene editing to investigate those questions in the laboratory.
Assess the biological results and use the evidence to guide the next experiment.
Our moonshot
Most medicine treats inflammation. We are going after what causes it.
We start with Crohn’s, where the genetics are clearest, and a method built to be repeated: select the target from patient data, correct it, measure whether it matters, decide on evidence rather than enthusiasm.
The disease is the first application. The method is the company.
Our focus today
Build the biological evidence through focused laboratory research.
Potential next applications
Explore where the approach could address related biological questions.
The wider ambition
Develop a research foundation that could be adapted across diseases with a genetic basis.
A long-term research ambition. Each new application would need its own biological evidence.
Our story
Alex Humphries, ViroDyn’s co-founder and scientific lead, lives with Crohn’s disease. For him, the questions behind the research are personal as well as scientific.
That perspective sits alongside ViroDyn’s research focus: using bioinformatics and laboratory investigation to explore the biology of Crohn’s disease.
Our team
Company builders, scientific specialists and advisers, working together around a shared research focus.
