Abstract 2835: Voruciclib, a clinical stage oral CDK inhibitor, sensitizes triple negative breast cancer xenografts to proteasome inhibition

Triple negative breast cancer (TNBC) is a highly heterogeneous disease, notoriously challenging to treat with standard chemotherapy options, and therefore is an area of intense focus for discovery of novel effective combination therapies. Here we used a previously described technology platform called CIVO, which enables assessment of multiple drugs and drug combinations simultaneously in living tumors, to identify drug combinations that result in synergistic anti-tumor activity in the HCC1187 model of TNBC. Our study focused on agents that combine with Voruciclib, a novel clinical stage oral CDK inhibitor with potent activity ( Citation Format: Joyoti Dey, Joseph Casalini, Sally Ditzler, Matt Biery, Angela Merrell, Derek Thirstrup, Marc Grenley, Richard Klinghoffer.
