Providing several target proteins to X-Chem, Otsuka will carry out clinical trials on its own for any compounds identified.

Otsuka will also retain exclusive rights to commercialise any products resulting from the collaboration globally.

The collaboration will see the deployment of X-Chem’s DEX libraries containing more than 120 billion individually DNA-encoded compounds.

X-Chem president and CEO Rick Wagner said: “Utilising X-Chem’s DEX platform, we hope to help create additional pathways for Otsuka to uncover candidate compounds.”
