Sunday Workshops

Two sessions of 2 workshops will be held during the afternoon of Sunday, October 9. Please register during the registration process. Each workshop is available at a fee of 85 euro.


Session 1 | 14:00-15:30

Workshop 1: Preparative HPLC of Peptides and Small Molecules: Phase Screening, Method Optimisation, Process Design

Where to start in preparative HPLC when a peptide or a complex active pharmaceutical ingredient has to be isolated in large scale? For many of the substances to be purified by preparative HPLC a certain method development and process design is needed. Either a generic method has to be developed which is able to separate a large number of substances following a certain protocol or – for production purposes – a specialized, highly optimized and economic production route has to be developed. This workshop will try to help developing a good, robust and efficient preparative HPLC method.

Using the example of the polishing step for the final purification of insulin you will learn about the importance of stationary and mobile phase selection. The workshop will demonstrate how methods developed at analytical column dimensions can be used to optimize a preparative method in different chromatographic regimes. Experiments to determine the physical properties needed for model based process design will be explained. Finally interactive simulation tutorials will be offered on batch and multi-column chromatography to optimize the process parameters.

Workshop 2: From Development to Commercial Scale: DoE, QbD, Regulatory, Process Validation

In this workshop, the complex path that is connecting the choice of the appropriate purification method to the start of a production campaign is discussed. The choice of the purification process will be challenged from different perspectives, which are often enter in conflict with the classical tools to evaluate the performance of a purification, like yield, throughput. All side aspects of a purification process will be discussed, starting from tank volumes, sampling, pooling, storage conditions, hold times, waste treatment, etc., to finish with how the process fits to the rest of process and, most importantly, to the final isolation step. An important part of the discussion will focus on the regulatory aspects connected to the development and validation of the process, like the definition of the critical process parameters, and on how concepts like Quality by Design (QbD) can help correctly framing the scale up process and dealing with the risks associated to it. Basic concepts of Design of Experiments (DoE) and Multi-Variate Data Analysis (MVDA) will be also introduced.

Session 2 | 16:00-17:30

Workshop 3: Multicolumn Processes: From Historical SMB to the Latest Advances in the Purification of Biomolecules

Multi-column (MCC) processes have become the workhorse of chromatographic separations. They are able to overcome the limitations of low throughputs and excessive solvent consumption that characterize conventional single-column processes. Despite the higher complexity as compared to single column processes, the design and operation of a MCC separations is in fact rather simple. The workshop will trace the developments in MCC starting from the classical SMB mainly used for small molecule purification and slowly progress to more recent innovations related to large-molecule purifications. The workshop will be held in three parts.

The first part aims at providing the fundamentals of the SMB technology. We will cover the basics of SMB technology: modeling, design, and optimization of SMBs; engineering issues associated to the industrial use of SMBs.

The second part covers recent advancements in multi-column chromatography. The increasing use of the SMB as a multipurpose unit in the pharmaceutical and fine chemistry industries has led to the development of novel cyclic operating schemes, some of which are substantially different from the conventional process. Broadly speaking, the new operating schemes introduce periodic modulations of selected control parameters into the operating cycle. We shall discuss concepts such as asynchronous port switching, cyclic modulation of feed concentration, time-variable manipulation of the flow rates, and solvent-gradient operation. We shall end our presentation with a discussion of the pros and cons of using SMBs with very few columns.

The final part deals with the use of multi-column chromatography for the purification of biomolecules. In the downstream processing of valuable therapeutic proteins, achieving high purity and high yield simultaneously, is a key prerequisite for the production of safe biopharmaceuticals at low and competitive costs. On the chromatography side, the use of cost-effective, non-affinity stationary phases and gradient chromatography in combination with multicolumn continuous chromatographic processes (MCSGP) presents an option for biopurifications. Advantages over batch chromatography include the possibility of simultaneous achievement of high yield and purity, a higher throughput and lower buffer consumption. We will discuss the fundamentals of these operations and discuss academic/industrial case studies.

The workshop is designed in such a way to require only a basic understanding of chromatography as a prerequisite; no previous exposure to the SMB technology is required. It will be an in-depth primer for the newcomers to the field, and it will offer a structured presentation of the MCC fundamentals to those aiming at a better understanding of the technology. The workshop will put all participants in the position to be able to follow and profit from the scientific presentations about MCC during the conference.

Workshop 4: Process Design for Purification of Biomolecules

Scale up of process chromatography of large biomolecules such as proteins, plasmids, virus, and virus like particles is the topic of this workshop. An introduction to the biophysical properties of these molecules will be given and consequently, which chromatographic models apply to describe the adsorption and desorption on chromatographic media. Chromatographic media most suitable for this type of molecules will be reviewed. Scale up rules will be addressed and how chromatographic processes can be designed to reach optimal productivity and selectivity. The critical process parameters will be highlighted and mathematical models will be described to explore the range of operation. The workshop will be completed with examples from industry, showing scale-up from mg to kg and highlighting operational constraints related to industrialization.
