New publication in European Urology demonstrates value of PredicineCARE liquid biopsy test for monitoring PD-L1 immunotherapy in patients with metastatic prostate cancer | News

HAYWARD, Calif., Sept. 16, 2021 /PRNewswire-PRWeb/ — Predicine, Inc. announced today results from a liquid biopsy study demonstrating the clinical application of utilizing the PredicineCARE liquid biopsy NGS assay to serially monitor changes in ctDNA levels in patients with metastatic castration-resistant prostate cancer (mCRPC).

The European Urology study evaluated the effects of administering a single fraction of SABR prior to the first and second doses of avelumab (PD-L1 immunotherapy drug) in patients with mCRPC. The study is entitled “Avelumab Combined with Stereotactic Ablative Body Radiotherapy in Metastatic Castration-resistant Prostate Cancer: The Phase 2 ICE-PAC Clinical Trial”. PredicineCARE, PredicineRNA and Low Pass-Whole Genome Sequencing (LP-WGS) assays were utilized in the study to monitor changes at cfDNA and cfRNA levels. The study demonstrated the potential value of serial monitoring of ctDNA levels in patients with mCRPC.

Due to the amount of time required to observe clinical or radiographic evidence of treatment efficacy, there is an unmet clinical need to utilize liquid biopsy assays to more quickly and non-invasively identify mCRPC patients who are responding to therapy. The data from this study suggests that baseline AR alterations, MYC gains, and high levels of baseline ctDNA fractions may be associated with a poorer prognosis. The study also demonstrates the potential for ctDNA analysis to identify patients who are responding to treatment prior to clinical and radiographic responses. Additionally, serial monitoring of ctDNA alternations and changes in copy number alterations demonstrate the ability to detect potential resistance mechanisms.

“This prospective study demonstrates the value of Predicine’s liquid biopsy solutions to monitor treatment response in patients receiving immunotherapy,” said Dr. Shidong Jia, Founder and CEO at Predicine. “We are pleased to provide a range of innovative liquid biopsy solutions that may have profound clinical implications including predicting patient survival, selecting therapies for treatment, monitoring for treatment response, and understanding subsequent resistance. Predicine was founded to address these types of unmet clinical needs. Our goal is to detect cancer early and treat early stages of cancer.”
