Mechanistic modeling of novel downstream processes - Developing process understanding with sparse data
11am EDT / 4pm BST / 5pm CEST

A brief introduction into mechanistic modeling of preparative chromatography, how fundamental natural laws can be employed to interpret complex data, understand the physicochemical phenomena and simulate processes for purposes of optimization and characterization. This talk will focus on how mechanistic modeling is especially beneficial for novel formats and their downstream processes, in which data may be sparse, variable or non-existent, material supply may be lacking and process or analytical variability is often problematic. By using experimental data with unparalleled efficiency, a mechanistic model enables one to interrogate a process in silico, enabling complete flexibility in evaluating process conditions, extrapolating outside of calibration data and ultimately generate process understanding.

New Purification Strategy for recombinant Human Insulin Produced in E. coli
9am EDT / 2pm BST / 3pm CEST

In the face of increasing global demand for insulin product, there is a pressing need to develop a more efficient and economical process for the production of recombinant insulin therapeutics. Here, we present a new and efficient downstream processing workflow for recombinant human insulin production using E. coli as the host system. For sample preparation prior to chromatography purification, Bio-Gel P-4 was identified as a very efficient resin for proinsulin desalting; for proinsulin purification, capture with Nuvia S AEX resin and elution in sodium citrate buffer achieved both good recovery (91-96%) and purity (81–84%); and for insulin purification, Nuvia HR-S AEX resin was found to be highly effective in removing a significant amount (~90%) of higher molecular weight cleavage product impurities. This new chromatographic process may serve as an excellent chromatographic tool for the purification of recombinant human insulin produced from E. coli Inclusion Bodies.

  • Insulin and proinsulin purification workflow
  • Effects of pH and conductivity
  • Resin characteristics and optimization

Improved antibody purification process through use of additives
10am EDT / 3pm BST / 4pm CEST

Downstream processing involves multiple unit operations including filtration and several chromatography steps that incrementally increases the purity of the target by exploiting the physical and chemical properties. It is critical for therapeutic monoclonal antibodies to have very high purity with low process related impurities like host-cell proteins (HCPs), DNA, leached protein A and aggregates in order to be administered to patients safely. We have identified a novel approach to improve impurity clearance efficiency of chromatographic steps by modulating the interaction of target protein and/or impurities with ligands on the resins. Protein A resin with high capacity (PROchievATM) or mixed-mode HIC resin (BakerbondR Poly Hi-propyl) is used for a capture step and additives are screened to reduce the non-specific binding of impurities. Following IEX steps are optimized to increase the capacity and removal of impurities such as residual HCPs, DNA, charge variants, aggregates and leached protein A.

Advanced Virus Filtration –High Protein Concentrations and Pump-Based Virus Filtration  
11am EDT / 4pm BST / 5pm CEST

Recently the requirements of virus filtration are changing. For example, the protein concentrations of process solutions are increasing, and the virus filtration step is operated not only with pressurized vessels but more and more with pump-based system. In this 2-part presentation, we discuss about “Advanced Virus Filtration – High Protein Concentrations and Pump-Based Virus Filtration”.

 

Increasing cell culture productivity and improving column chromatography performance in the past several years have resulted in virus filtration feeds with higher protein concentrations. Feed solutions at higher protein concentrations can present some challenges for example the potential increase in aggregation formation which in turn can affect filterability. However, one main benefit at higher concentration is the reduced filtration surface area needed and therefore the cost, providing that the nanofilter can handle this increase in concentration. Other benefits include reduced processing time and reduced footprint. Planova BioEX exhibits high throughput with high concentration mAbs and the addition of Virosart Max prefilter can further improve filterability by removing aggregates.

Viral clearance validation studies are typically performed using small-scale filters operated by applying constant pressure to a feed vessel, while at large-scale it is favored to use pump-based systems utilizing single-use bags, which offer improved footprint and portability. Pump-based filtration processes present more process complexity, more potential for process fluctuations, and more challenges in scaling. We have performed studies to better understand pump-based virus filtration operations using Planova™ filters. We show that Planova 20N filters provide effective viral clearance even in the presence of large fluctuations in transmembrane pressure across all filter sizes and obtain comparable results with that of using constant pressure.

Ligand Discovery Strategies for Improved Custom Purification Solutions
10am EDT / 3pm BST / 4pm CEST

The increasing diversity and complexity of new advanced therapy medicinal products (ATMPs), with unique and non-standard technology approaches, is creating challenges in the biomanufacturing industry. The lack of downstream processing platforms that can accommodate this diversity often results in long processing times with high loss of yield. Custom affinity ligands are designed for specific applications and can therefore significantly improve bioprocessing economics by reducing the number of process steps and increasing the capture and recovery of ATMPs.

This presentation outlines strategies for ligand design and screening. We discuss the ligand discovery process, considering approaches for the information available, such as the target protein structure, binding site and known ligands or inhibitors. Additional factors such as stability, yield and cost will also determine the choice of ligand library, so the presentation includes the following topics:

  • Understanding the ligand discovery process
  • The advantages of using synthetic ligand libraries
  • How Affimer® ligand technology offers unique solutions for affinity purification

Development and performance of an HCP quantification method at Lonza using the Gyrolab® xPand
9am EDT / 2pm BST / 3pm CEST

Host cell proteins (HCPs) are one of the major part of process-related impurities during manufacturing of protein-based biopharmaceuticals. They are considered a critical quality attribute (CQA) due to their potential immunogenicity and impact on product stability. Typically HCPs are routinely monitored by ELISA commercial kits, whose performance primarily relies on the capability of the employed anti-HCP antibodies to cover HCPs. This method is reliable for early phases projects but does not provide a full coverage of the total population of HCP. In addition, ELISA method can be time consuming and laborious. Since in Lonza IBEX we use Xceed cell line as a platform for Process development, we generated antibodies against HCPs of this specific cell line to reach an optimal and precise quantification of HCP impurities. We developed an HCP quantification method using the Gyrolab® xPand as a semi-automated platform technique. With specific Gyrolab Bioaffy™ CDs and method generated by Gyros Protein Technologies, we obtained high working range and high sensitivity in the low-concentrated part of the standard curve. Finally, we compared performance results in HCP quantification between ELISA and Gyrolab xPand methods showing similarity for most of our Downstream in-process samples.

Mechanistic modeling of chromatography: reducing timelines and improving outcomes
10am EDT / 3pm BST / 4pm CEST

Shorter timelines, larger data requirements. How can you balance the need to reduce time to experiment, time to clinic, and time to market while generating data comprehensive enough to avoid extended review?

Mechanistic models offer a way to negotiate a rapidly diversifying pipeline of molecules. Mechanistic models — mathematical interpretations of physiochemical interactions in chromatography — are already making a profound impact on the workflow of process development.

In this talk, we will review in-silico process development and data-driven decisions to see how mechanistic models can help you reduce timelines and improve outcomes with greater predictive power, both within and outside of the explored characterization space.
