Predicting T‐cell quality during manufacturing through an artificial intelligence‐based integrative multiomics analytical platform

Abstract

Large‐scale, reproducible manufacturing of therapeutic cells with consistently high quality is vital for translation to clinically effective and widely accessible cell therapies. However, the biological and logistical complexity of manufacturing a living product, including challenges associated with their inherent variability and uncertainties of process parameters, currently make it difficult to achieve predictable cell‐product quality. Using a degradable microscaffold‐based T‐cell process, we developed an artificial intelligence (AI)‐driven experimental‐computational platform to identify a set of critical process parameters and critical quality attributes from heterogeneous, high‐dimensional, time‐dependent multiomics data, measurable during early stages of manufacturing and predictive of end‐of‐manufacturing product quality. Sequential, design‐of‐experiment‐based studies, coupled with an agnostic machine‐learning framework, were used to extract feature combinations from early in‐culture media assessment that were highly predictive of the end‐product CD4/CD8 ratio and total live CD4+ and CD8+ naïve and central memory T cells (CD63L+CCR7+). Our results demonstrate a broadly applicable platform tool to predict end‐product quality and composition from early time point in‐process measurements during therapeutic cell manufacturing.

Fitting Adsorption Isotherms with Symbolic Regression

“…SR is a simple, non-physics-based approach to creating models to fit data. This means SR can be a very powerful tool for fitting datasets where the physics are extremely complex or poorly understood, and DataModeler has been used with success in several of these cases. − In general, physical phenomena in adsorption tend to be well-understood and many physics-based theoretical models are available for common isotherm types . A physics-based model that fits a given dataset contains several intrinsic advantages over a purely empirical model that provides an equally satisfactory fit.…”

Robotics-driven manufacturing of cartilaginous microtissues for the bio-assembly of skeletal implants

“…A machine learning classifier can predict the failure of the microtissue manufacturing process and support informed decision making in the early stages of cell culture. Ultimately, this can help process optimisation to achieve full process control (71)(72)(73)(74).…”

High-density microbioreactor process designed for automated point-of-care manufacturing of CAR T cells

“…Apart from being potential future manufacturing platforms, scaled-down microbioreactors could also be valuable process development tools. There is a general lack of process understanding in cell therapy manufacturing 17,52,53 , partly due to the lack of suitable manufacturing technologies at the appropriate scale. This microbioreactor, with four pods per system, and on-board environmental measurements that allow greater process control and predictability, could facilitate future high-throughput process characterization under controlled conditions.…”
