Studies shows that, JAB-30355 has shown very high binding affinity to P53 Y220C mutant proteins. Tumor regression was achieved in multiple cancer models covering various tumor types, such as gastric cancer, ovarian cancer, breast cancer and lung cancer. The synergistic effect was found when combined with chemo or oncogenic protein inhibitors which indicates a widely combo potential of JAB-30355.

There is only one P53 Y220C activator program in the Phase I clinical stage globally. JAB-30355 is expected to be one of the first P53 Y220C activator to be approved.
