SMART Chromatography™ - Feed Stream Clarification and Primary Purification in a Single Unit Operation

Presenter: Alistair Hurst

Since the COVID-19 pandemic, supply chain issues in the biomanufacturing sphere have meant that the traditional approach to the production of biologicals, for example monoclonal antibodies, has become considerably more expensive.  Optimisation of both the upstream and downstream operations requires a new approach.  Furthermore, with the advent of larger bioentities such as Adeno Associated Virus (AAV) and Lentivirus (LV) these traditional methods result in very low recovery of the target entity and, as a direct result, much higher production costs.

SMART Chromatography™ removes the necessity to clarify the target containing feed stream before application to the primary capture column.  The whole, undiluted, unmodified feed stream is passed through the column, thus combining the unit operations of clarification and primary purification into a single, linearly-scalable step.

Tosoh Bioscience

Multi-Column Chromatography: A Solution for Modern Biomanufacturing Challenges

Presenter: Marissa Heino

In this talk, we dive into the world of downstream purification intensification. Tosoh addresses current biomanufacturing challenges with a holistic approach to downstream intensification using multi-column chromatography (MCC) on the Octave BIO (a benchtop MCC system for process development), the Octave PRO (a GMP-ready system for clinical and commercial manufacturing) and SkillPak pre-packed columns. MCC offers potential benefits such as increased productivity and resin utilization, decreased consumable costs and reduced clean room footprint. Through a collaborative case study with a CDMO, we show these concrete efficiency gains for Protein A chromatography.

Using BioSolve modeling software, we present a comparison of processing times, material costs, and non-material costs for purification platforms at varying titers, considering both pre-packed and self-packed columns. The results affirm that transitioning to MCC can effectively address current challenges in downstream purification and biomanufacturing.

Case Studies with Hydrophobic Interaction and Mixed-Mode Chromatography: Flow-Through Technologies for mAb Polishing.

Presenter: Jett Appel, Purification Staff Scientist, Field Applications

Advancements in the engineering of monoclonal antibodies (mAbs) have led to additional challenges in the purification of these modalities including high levels of aggregates. Ion exchange chromatography is often not sufficient to achieve the purity targets, so hydrophobic interaction chromatography (HIC) as well as mixed-mode resins are needed as orthogonal tools. These technologies can be implemented in flow-through mode allowing for high loadings and fast processing times, making them well-suited for large-scale implementation.

This presentation reviews case studies using POROS Benzyl Ultra (HIC) and POROS Caprylate (mixed-mode cation exchange).  First, a mAb with high starting levels of aggregates was purified effectively utilizing flow-through HIC chromatography while also achieving robust retrovirus clearance.  Secondly, a novel antibody format utilizing synthetic amino acids intended for site-specific drug linker conjugation presented unique purification challenges with aggregates and host cell proteins (HCPs).  Flow-through HIC achieved the desired reduction of these impurities along with effective clearance of model retro- and parvoviruses.  Lastly, the aggregate levels were significantly reduced from a mAb using POROS Caprylate in flow through mode.  Some critical and challenging HCPs were also removed with this technology.

These case studies illustrate how novel chromatographic tools can improve the purification processes for complex therapeutics.

Practical Approaches to Purification of Oligonucléotides and Peptides Using High-Performance Liquid Chromatography

Presenter: Sandeep Kondaveeti, Biopharma Account Manager

A crucial step in any pharmaceutical production is the purification of the Product The purification of Bio therapeutics such as oligonucleotides (ONs) can be particularly challenging because of the high similarity of target and impurities. Therefore, high-performance liquid chromatography (HPLC) is the method of choice if high-purity products are desired. Preparative separations become an economic decision as we balance the cost of solvents, adsorbents and time. In this presentation, the focus will be on the most common purification challenges today; that of oligonucleotides, peptides and the high throughput method development.  Optimal analysis relies on LC System with precise gradient mixing, even at high flow rates, pump heads that are compatible with a wide pH range and salt concentration, and choosing the correct trigger ion of the desired compound which will lead to better fraction collections resulting in higher final products.  We will discuss the best workflow solution needed to achieve ideal purification.

Key Learning Objectives :

  • Analytical to preparative chromatography workflow
  • About strategies to efficiently develop methods for purification success.
  • Column technology and method optimation for purification of Peptides and oligonucleotides sample modalities

Sartobind® Rapid A: Economical and Technical Considerations of Multi-Batch Use

Presenter: Ana-Raquel Fortuna

Although compatible with single-use processes, the investment on affinity media for capture of mAbs can be difficult to justify for one single batch, especially in early phases of the process development. In this presentation, we want to highlight how sanitization and cleaning-in-place protocols allow Sartobind® Rapid A to be re-used for several batches and how multi-batch use impacts the purification performance and total cost of ownership. Optimally we will present a customer use-case (pending approval) and the economic analysis will compare different scenarios using a comprehensive Sartorius tool, used in customer consulting context.
