PrediCTC, liquid biopsy in precision oncology: a technology transfer experience in the Spanish health system.

Abstract

Purpose: Management of metastatic disease in oncology includes monitoring of therapy response principally by imaging techniques like CT-Scan. In addition to some limitations, the irruption of liquid biopsy and its application in personalized medicine has encouraged the development of more efficient technologies for prognosis and follow-up of patients in advanced disease. Methods: PrediCTC constitutes a panel of genes for the assessment of Circulating Tumor Cells (CTC) in metastatic colorectal cancer patients, with demonstrated improved efficiency compared to CT-Scan for the evaluation of early therapy response in a multicenter prospective study. In this work, we designed and developed a technology transfer strategy to define the market opportunity for an eventual implementation of PrediCTC in the clinical practice. Results: This included the definition of the regulatory framework, the analysis of the regulatory roadmap needed for CE mark, a benchmarking study, the design of a product development strategy, a revision of intellectual property, a cost-effectiveness study and an expert panel consultation. Conclusion: The definition and analysis of an appropriate technology transfer strategy and the correct balance among regulatory, financial and technical determinants are critical for the transformation of a promising technology into a viable technology, and for the decision of implementing liquid biopsy in the monitoring of therapy response in advanced disease.
