Abstract 3410: AVATASCAN®, a pioneer of functional precision medicine in guiding clinical decision-making

Abstract

Abstract Precision medicine refers to the tailoring of individual therapeutics based on each patient’s genetic, phenotypic, and clinical characteristics, therefore seeking the most effective treatment for the patient. With recent advances in genome sequencing technology, it was anticipated that identifying specific genetic alterations would contribute greatly to the realization of precision medicine. However, most cancer patients do not benefit from genomic precision medicine, as shown in recent Next Generation Sequencing (NGS)-driven clinical trials. Functional precision medicine directly uses patient tumor cells to test their ex vivo responses to diverse drugs to predict the most effective drugs. Functional precision medicine is emerging because it provides immediate translatable information to select drugs among clinically available therapeutics. AVATASCAN®, developed by Samsung Medical Center and AimedBio Inc., is a robust and accurate high throughput functional precision medicine platform with more than 1,500 historical sample data. AVATASCAN® has tested more than 1,500 cancer patient samples across 14 different tumor types, including glioblastoma, lung, colorectal, stomach and breast cancers. We achieved a tissue culture success rate and a drug screening success rate of more than 90% in most tumor types. A retrospective analysis of the clinical outcomes of patients given matched drugs demonstrated actual complete/partial response in 85% of AVATASCAN® screening responders. Recognizing its potential for clinical application, AVATASCAN® was selected as one of the datasets referenced by the pediatric tumor board at Seoul National University Hospital for clinical decision-making. Furthermore, AVATASCAN® is now available in Singapore and Thailand as an early-access, premium precision medicine service. Overall, we present compelling evidence that AVATASCAN® is a valuable platform for personalized cancer therapy. Therefore, we are moving forward to adopt and expand this platform in clinical applications.
