BM-Stratified Cohorts with Prospective Response Prediction Subjects with high-grade EC ≤3 lines of prior therapy The ACR-368 OncoSignature™ is a tumor agnostic, functional Biomarker (BM) test designed to prospectively predict benefit from ACR-368 (prexasertib), a potent, selective CHK1/2 inhibitor. It is composed of 3 protein biomarkers that measure the tumor’s addiction to CHK1/2-mediated DNA repair independent of genetic alterations. Screening with Acrivon’s OncoSignature BM test across routine-processed (FFPE) human tumor types, predicted endometrial cancer (EC) to be particularly sensitive to ACR-368.
