Event: BPI Ask the Expert
Date: March 3, 2022
Speaker: Rok Sekirnik, Head Process Development for mRNA and pDNA
In this webinar, we will discuss an HPLC-based analytical method using a multimodal ligand based on anion exchange/hydrogen-bonding ligand (PrimaS) to monitor the IVT reaction, which allows for simultaneous quantification of NTPs, capping reagent, plasmid, and mRNA within 3.5 min.
Event: Cell and Gene Therapy Insights webinar
Date: February 17, 2022
Presenter: Ales Strancar, Managing Director
Key learning points:
- One of the key challenges in manufacturing viral vectors is to increase the ratio between empty and full capsids.
- When the expression in the cell line results in less than 10% full capsid it is quite impossible to reach better than 90% full in the final product. It is therefore mandatory to optimise the USP to result in better empty/full ratio.
- This can be efficiently realised by using at-line PATfix to allow for analysis of the full and empty capsids ratio directly in the harvest.
- The residual empty capsids can be removed by polishing step using different anion exchange columns.

Event: Late Stage Bioprocessing & Viral Vectors 2 11 November 2021
Date: November 3, 2021
Abstract:
Adeno associated virus (AAV) is the leading vector in the field of gene therapy because of its low toxicity, good overall safety profile, and ability to maintain stable expression for long periods of time. It is therefore crucial to develop a robust and high efficiency platform for its manufacturing.
One of the key challenges in manufacturing viral vectors is to increase the ratio between empty and full capsids. The most efficient way is to design the USP to result in less than 10% of empty capsids. This can be realised by process optimisation using at-line PATfix analytics to allow for analysis of the full and empty capsids ratio during the virus expression.
Fast and reliable at-line analytical methods to allow for process optimisation USP and DSP, and assessing the purity of the final product using PATfix system will be presented.

Abstract:
Global demand for pDNA production is at an all time high, due to increased need from Gene Therapy ramp-up. pDNA, as an enabling product, is critical in production of mRNA, AAV and other therapeutic vectors. Increasing yield and purity in the production of pDNA is a vital step in meeting such demand. Supporting reliable in-process control during pDNA purification, PATfix pDNA analytical platform is enabling rapid process development and optimization while providing a reliable analytical platform for production runs.

Event: 2nd Annual Gene Therapy Analytical Development EU
Date: May 26, 2021
Abstract:
In-process analytics of vector capsid production is a critical optimization target in development of AAV-based gene therapy products. In this presentation we introduce a fast at-line HPLC based system that enables differentiation of vector capsid and empty capsid production in transfection mixtures. Case study results demonstrating the effects of different process variables on capsid production and assembly are shown and insights about purification are also discussed.

Messenger RNA is poised to become a major contributor in the fields of gene therapy and vaccines. Making this a practical reality requires purification technology that accommodates its unique features and challenges. Some of those challenges are inherent to mRNA. Others are byproducts of RNA synthesis.
This presentation addresses both and introduces a coordinated purification toolbox to advance the evolution of mRNA therapy.
