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
It is demonstrated that RP-3467 potently suppresses Pol{theta} enzymatic activity, abrogates MMEJ, and disrupts mitotic DNA repair in HR-deficient (HRD) models, inducing synthetic lethality.
