Workshop 1 - Continuous Chromatography for Small Molecules : Principle, Process Development and Large Scale Manufacturing

Dr Olivier Dapremont (AMPAC Fine Chemicals)

Abstract

In this workshop, the students will learn the basic principles of continuous chromatography for the separation of small chiral molecules using the Simulated Moving Bed process.  The instructor  will introduce the mathematical modelling using the triangle theory to evaluate the performance of the separation and the influence of various parameters.  Once the basic concepts are in place, the instructor will discuss improvements to the technology and the extension of the process to more complex separations.  Finally, the student will learn how to develop an SMB separation from the initial screening to the implementation at commercial scale. 

Biography

Dr Dapremont received his Ph.D. degree in Chemical Engineering and Applied Chemistry in Simulated Moving Bed technology (SMB) and chiral applications in 1997 from the University of Pierre and Marie Curie in Paris France.

He started his career, in 1992, developing SMB technology for Prochrom R&D, France.  In 1997, He joined Chiral Technologies Europe, France, were he was in charge of the kilo lab for SMB chiral separations service.

He joined Aerojet Fine Chemicals, now AMPAC Fine Chemicals (AFC) in Rancho Cordova, CA, at the beginning of 2001.  At AFC, Dr. Dapremont is in charge of the development of continuous processes for APIs and intermediates including chromatographic processes as well as implementing flow chemistry and related techniques at large scale.  To this day, he has developed and implemented over 50 chiral and non-chiral separations using SMB from kilogram to multi ton scale.

Dr. Dapremont is author and co-author of several articles on preparative chromatography and SMB applications in various scientific journals and magazines.  He is co-inventor on multiple patents using SMB as a purification step for APIs and he is a recognized expert in the field for the past 25 years.

Dr. Dapremont is also a member of the Organizing Committee of the Prep Symposium conference and a member of the Scientific Committee of the SPICA conference.

Workshop 2 - Introduction to Machine-Learning Methods for Process Development. From Multivariate Analysis to Hybrid Models

Dr Alessandro Butte (ETH Zürich)

Abstract

In the last years, the use of machine learning (ML) algorithms has increase exponentially also in the context of process development and manufacturing. These tools, together with the progressive digitalization of all processes, procedures and data, the use of advanced sensors, and the possibility of putting different process units in direct communication with each other, is at the basis of what it has been called Industry 4.0.
This course is intended to introduce the participants to the main statistical and machine learning techniques that are typically used in the context of process development and manufacturing, with a particular view on the application to the so-called downstream processes and to chromatography in particular. The participants will be given an overview on all techniques, how and when to apply them, some theoretical background, and addition to relevant industrial application examples.

First, some basic statistical concepts (likelihood, p-values, etc.) will be given, together on a discussion on how to organize and prepare data. Then, an overview of the main multivariate data analysis (MVDA) methods will be given. This includes principle component analysis (PCA) and partial least square (PLS) regression. Then, an overview on the main ML methods for regression and classification will be given. This includes decision trees (DT) and random forests (RF), support vector machine (SVM), artificial neural networks (ANN), kernel ridge regression (KRR) and gaussian processes (GP). For all these techniques, focus will be put on the training and validation methods.

After introducing ML, the focus will move from purely data driven models to so-called hybrid models, where both mechanistic knowledge and data information are fused together to enhance data utilization and model robustness and predictability. Examples from chromatography will be given.
Finally, a brief overview will be given to experimental design and, in particular, on model based experimental design using the aforementioned methods.

Workshop 3 - Prep Chiral and Achiral SFC : Principles and Applications

Workshop 4 - Application of Machine-Learning Methods to the Production of Therapeutic Proteins

Prof. Massimo Morbidelli (ETH Zürich)

Abstract

In the last years, there has been an increased interest in continuous and integrated manufacturing of biopharmaceuticals, due to increasing cost and time pressure in industry, as well as new drug formats asking for more flexible production concepts. The next step towards intensification and modernization of current manufacturing technologies will be based on the use of online process control and optimization techniques. This requires the appropriate use of statistical approaches and machine learning techniques - not only in a continuous manufacturing scenario, but also within the more traditional batch integrated processes.

In this workshop, we discuss results obtained through hybrid approaches, where such machine learning techniques are used online in combination with traditional mechanistic models. Applications include : development of soft sensors for up and down stream monitoring (Raman based), online maintenance (prediction of protein A substitution in a monoclonal antibody capture process), hierarchical online process control and optimization of a chiral SMB process and a capture twin column unit.

The illustrated results mainly, but not only, refer to a end-to-end integrated continuos unit for the production of an industrial monovalent antibody of industrial relevance. They provide a very important basis to intensify the main advantages of continuous integrated manufacturing in agreement with the trends of industry 4.0.
