Targeting Polθ Helicase with RP-3467: Preclinical Validation and Clinical Response in a gBRCA1 ovarian cancer patient with an acquired PARPi resistance mutation in TP53BP1
Homologous recombination (HR) deficiency underlies a range of cancers, and PARP inhibitors (PARPi) targeting this vulnerability have demonstrated clinical efficacy in BRCA1/2-mutant tumors. However, resistance mechanisms and tolerability issues limit their long-term clinical effectiveness. Here, we characterize RP-3467...
