LB-100 (PP2A Inhibitor) and Azenosertib (WEE1 Inhibitor) in Metastatic Colorectal Cancer Patients

This Phase Ib trial studies the side effects and best dose of LB-100 and azenosertib for the treatment of patients with metastatic colorectal cancer. Azenosertib blocks a protein that is involved in the repair of damaged DNA, this protein is called WEE1. Inhibiting WEE1 drives cancer cells into a state of cell division without repair of the damaged DNA, resulting in cell death. LB-100 has been shown to make anticancer drugs work better at killing cancer. LB-100 blocks a protein called PP2A. Blocking this protein increases the stress signals for the tumor cells that express PP2A. Research has shown that azenosertib and LB-100 may enhance each others effect when treating metastatic colorectal cancer.
