Project Description

Advanced Therapy Medicinal Products (ATMPs) are perceived as key enablers for personalized medicine. For example, proliferated Natural Killer (NK) cells can be used for cancer treatment. However, NK cell attributes differ from donor to donor, leading to large process variations and finally to mismatch in product quality. Hence, next generation therapy processes have to be technologized. However, the cellular complexity of metabolism, differentiation and function is too large to reply on pure measurements only. Our hypothesis is that a digital twin based approach can yield efficiently to the desired robust and stable expansion process.

Therefore, this PhD project focusses on the development of kinetic and metabolic process models to describe and steer NK cell expansion to optimal and reproducible Critical Quality Attributes (CQA). Based on real-time implementation as digital twin, critical process events can be predicted to achieve a robust expansion step and constant CQAs across multiple donors. This PhD therefore is a translational opportunity to use our reputed tools of PAT, experimental design and digital twins on NK-ATMP processes and allow for providing platform knowledge for next generation biopharmaceuticals.

Key Goals and Tasks

The primary aim of this PhD thesis is to develop and deploy digital twins to technologize and enable robust ATMP processes, using NK cells as a model system.

Tasks:

  • Learn NK cell cultivation techniques and analytics as established in our labs
  • Gather process understanding by relating CQAs to raw material attributes and process parameters using multivariate experimental designs
  • Convert the gathered process understanding in hybrid models using good modelling practice workflows
  • Set up the Process Analytical Technology (PAT) strategy and deploy the model in real time as digital twin. The real time environment is well established in our labs.
  • Verify the robustness of the digital twin predictions, refine the hybrid model by using different starting materials and process conditions
  • Publish high impact publications in this novel and emerging field of enabling affordable drugs for the world
