About VADA
The VADA program targets the protein vaccinia-related kinase 1 (VRK1). The program aims to develop drugs targeting a family of proteins involved in the cell's response to DNA damage (DNA damage response, DDR) and control of the cell cycle. Elevated levels of this protein family are found in a range of cancers and are correlated with poorer survival. VRK1 inhibitors have the potential to work in combination with other targeted treatments, radiotherapy or chemotherapy.
