CB-5083 is a novel first in class, potent orally bio-available p97 inhibitor that disrupts cellular protein homeostasis and demonstrates anti-tumor activity in solid and hematological models . CB-5083 causes rapid and sustained accumulation of poly-ubiquitin in tumor xenografts after a single administration. CB-5083 showed activity to inhibit tumor growth in multiple rodent models of human cancer. Furthermore, CB-5083 appears to exhibit greater potency over current proteasome inhibitors that further validate targeting p97 and protein homeostasis in the treatment of cancer.
