Overview

NCI Definition [1]:
An orally bioavailable, adenosine triphosphate (ATP) competitive inhibitor of polo-like kinase 1 (PLK1; PLK-1; STPK13), with potential antineoplastic activity. Upon administration, onvansertib selectively binds to and inhibits PLK1, which disrupts mitosis and induces selective G2/M cell-cycle arrest followed by apoptosis in PLK1-overexpressing tumor cells. PLK1, named after the polo gene of Drosophila melanogaster, is a serine/threonine kinase that is crucial for the regulation of mitosis, and plays a key role in tumor cell proliferation. PLK1 expression is upregulated in a variety of tumor cell types and high expression is associated with increased aggressiveness and poor prognosis.

Onvansertib has been investigated in 4 clinical trials, of which 4 are open and 0 are closed. Of the trials investigating onvansertib, 2 are phase 1/phase 2 (2 open) and 2 are phase 2 (2 open).

Deficient DNA Mismatch Repair (dMMR), KRAS Exon 2 Mutation, and KRAS Exon 3 Mutation are the most frequent biomarker inclusion criteria for onvansertib clinical trials.

Colorectal carcinoma, pancreatic ductal adenocarcinoma, and prostate adenocarcinoma are the most common diseases being investigated in onvansertib clinical trials [2].
