Drug repurposing for Cancer Precision medicine: High-Throughput Drug Screening as an integrative precision medicine platform in drug repurposing

Optimizing Drug discovery and Translation is one of the key tracks in Global Challenges Annual meeting 2019 and is the critical factor in achieving UN Sustainable Development Goals 3 Good Health and Well Being. WHO reports Cancer is the second leading cause of death globally with the estimated 9.6 million deaths in 2018 (1 in 6 death is due to cancer). In additional, 70% of mortality from cancer occur in low- and middle-income countries such as South Africa. Relevance to the low- or middle-income country setting and Grand Challenges: Recent report from Discovery Medical Schemes states that cancer causes more death in South Africa than HIV, Tuberculosis and Malaria. Leukaemia is one of the top ten most common cancer in South Africa. In addition, leukaemia is the most common childhood cancer (25.4% of all cancers) in South Africa, which is similar to rates in other countries. Currently, there is drive at South Africa by DSI, CSIR and MRC to establish a precision medicine program that would address the needs of South African Patient cohort. My functional precision medicine strategy is designed to directly identify tailored drug regimens that target individual patient´s cancer cells and give benefit to the same donors by supporting clinical decision-making. We aim for this project to serve as a proof of concept to showcase whether individually designed high throughput drug sensitivity screening along with microfluidics based single cell drug screening can provide patient benefit with limited material available and to build competence on existing drug sensitivity screening at CSIR using newly developed platform technologies such as microfluidics based single cell drug screening. The proposed project is therefore well aligned with the strategy of present drive of South African Precision Medicine initiative.
