CDx for Drug Repositioning


A major challenge of chemotherapeutic agents is the selection of the eligible patients. Specifically, 1 st generation of anti-cancer drugs acts on cells without tumor selectivity and have limitation for the personalized treatment of cancer patients' This emphasizes the urgent need to develop predictive biomarkers. The development and clinical implementation of biomarkers that predict response t。 cytotoxic drug could facilitate selecting the most efficacious therapeutic regimen given the molecular characteristics of an individual 's tumor. Furthermore, predictive biomarkers could repurpose commonly used chemotherapeutic drugs in new indication and produce the highest value with low risk


Hepatic arterial infusion chemotherapy (HAIC) with Cisplatin and 5-Fluorouracil has been used in advanced HCC. HAIC with cisplatin and 5-FU is superior in its efficacy to that of Sorafenib. Previously, we identified that HMGB2 suppressed Cisplatin-induced cell death in HCC cell lines. Based on the result, we designed a phase 2b prospective clinical trial to assess the efficacy and the safety of HAIC of Cisplatin and 5-luorouracil in advanced HCC patients stratified by HMGB2 gene expression as a biomarker predicting therapeu tic response to Cisplatin. Currently, IND of the protocol was approved by Korea FDA and the clinical trial is in progress in 11 medical centers.
