[Webinar Recap]Translational Applications of MiniPDX: An In Vivo Organoid Assay in New Drug R&D


On November 18, Danyi Wen from Shanghai LIDE Biotech, described a novel drug efficacy test using Patient Derived Xenograft (PDX) samples to measure drug efficacy and identify therapeutic candidates in personalized oncology treatments. LIDE’s novel MiniPDX is a 7-day, in vivo drug efficacy test for oncology therapeutics. It is the in vivo version of a 3D organoid assay and correlates with traditional PDX by 92%, and with clinical end point at 82%. These high correlations make MiniPDX an effective option to test targeted drugs, chemotherapies, angiogenesis drugs, and more, while demonstrating superior testing times and cost-effectiveness versus traditional PDX. In a clinical setting, MiniPDX, together with next-generation sequencing (NGS), is playing an emerging role in personalized oncology.

The process starts with a freshly prepared cell suspension from either a clinical sample or PDX (Patient Derived Xenograft) model. This sample is sealed into a mini capsule with 500 KD cut-off pores. Capsules are implanted into SCID mice subcutaneously, and a test compound is given systemically for 7 days. The efficacy of the test compound is then evaluated by measuring ATP of the cancer cells in the capsule.

The MiniPDX mouse trial can also be coupled with “K-Cell Omic” analysis (DNA, RNA, and Protein), presenting a powerful tool for the identification of drug candidates and the discovery of companion diagnostic markers.
