Acrivon Gets 2 Fast Track Designations for Prexasertib
FDA has granted Acrivon Therapeutics two fast track designations for developing ACR-368 (prexasertib) in platinum-resistant ovarian cancer and endometrial cancer. The targeted DNA damage response inhibitor therapy is being studied in a multicenter, open-label, single arm Phase 2 clinical trial in patients with platinum-resistant ovarian cancer, endometrial adenocarcinoma, and urothelial cancers based on OncoSignature-predicted sensitivity to ACR-368, the company says. Acrivon has obtained exclusive rights to develop and commercialize ACR-368 under a license agreement with Eli Lilly.
The companion diagnostic OncoSignature uses proteomic biomarkers to identify the patients most likely to benefit from a drug candidate, Acrivon says. “We have shown that the ACR-368 OncoSignature test was able to predict drug responders in blinded, prospectively designed studies on pretreatment tumor biopsies collected from past clinical trials and in patient derived xenograft studie,” it adds.
Acrivon also says ACR-368 has shown “deep, durable single-agent activity, including complete responses, in a proportion of patients across several Phase 2 studies, including platinum-resistant ovarian cancer, squamous cell cancer of the head and neck, as well as anal cancer for which Orphan Drug Designation has been granted.”
