Overview

Pol θ-Helicase inhibitor is a preclinical-stage small molecule developed by QuantX Biosciences for the treatment of solid tumors. It specifically targets the helicase activity of DNA polymerase theta (Pol θ), a key component of the microhomology-mediated end joining (MMEJ) DNA repair pathway. This pathway serves as an alternative repair mechanism in cancer cells that are deficient in homologous recombination (HR), such as those with BRCA1 or BRCA2 mutations. By blocking Pol θ, the inhibitor aims to exploit synthetic lethality, leading to the accumulation of DNA damage and subsequent cell death in HR-deficient tumor cells while minimizing impact on normal cells.
