This paper shares industry feedback after the publication of two BioPhorum papers that complement ongoing efforts in the wider CGT field. It supplements these publications by delving into identity testing and cross-contamination for plasmid master cell banks and plasmid DNA, and other plasmid DNA release tests (including DNA homogeneity, residual DNA and host RNA, and sterility or bioburden).

Historically, the biopharmaceutical industry has relied on traditional pharmaceutical manufacturing practices to make and release products. This publication examines the future of biopharmaceutical manufacturing by presenting the vision of fully implemented in-line monitoring (ILM) and real-time release. This aspirational vision includes full ILM, predictive analytics and advanced process controls (APC) enabling release of product in real time, with concomitant predictive and preventative alerts and resolution of process, equipment and other production issues.
This paper discusses the issues around trace elements and gives a suggested approach for developing a method for analyzing trace elements in cell culture media and hydrolysates. The approach is based on a ground breaking BioPhorum collaboration that shared blinded data and compared analytical methods between biopharmaceutical and media manufacturers.
The BioPhorum Gene-Editing subteam have produced a member only tool enabling the end-user to determine comparisons between different gene-editing techniques and delivery methods which can be used in cell and gene therapy drug product development and manufacture. The tool allows the user to form individual conclusions based on the users' requirements.

Feedback on the FDA draft guidance for industry studying multiple versions of a cellular or gene therapy product in an early phase clinical trial
This member document summarizes consolidated feedback and recommendations from a collaboration of BioPhorum members on the FDA draft guidance for industry studying multiple versions of a cellular or gene therapy product in an early phase clinical trial consultation.
In its current state, cell therapy manufacturing comprises several open and manual operations which increase the risk of contamination. Members of BioPhorum’s Cell & Gene Therapy Commercialization workstream have generated a ‘mock’ process detailing the manufacture of a generic autologous CAR-T product operated through a series of process steps combining some open and some closed system elements. The mock process has undergone an end-to-end closure analysis to identify those operations that pose the highest contamination risks, and to provide suggested mitigation solutions to minimize such risks. Suggestions include options that are currently available, as well as potential future ‘desired state’ options. This paper details the full process and summarizes potential risks and possible mitigations. The primary aim of this paper is to demonstrate systematic application of a closure analysis method on an ex vivo gene therapy (also known as gene-modified cell therapy) process so that organizations can apply similar analyses to their own processes. The secondary aim is to propose process closure solutions that companies could implement in their own operations.
While previously only found in academic, pre-clinical and early clinical stages, RNA technologies, including mRNA therapeutics, have emerged as a promising drug modality due to their essential biological role in protein expression and their potential versatility in manufacturing. RNA is in the global spotlight and is being
prioritized due to the COVID-19 pandemic. However, to maintain the current momentum as industry and agencies return to a ‘normal’ cycle of development for a wider range of drugs and therapies, experts in this field need to come together to identify and address challenges unique to the RNA modality. BioPhorum has started this by bringing together industry leaders to identify RNA-focused manufacturing challenges, and is working toward solutions to common challenges and improving current processes. The purpose of this article is to introduce this critical area and to show the unique RNA challenges, not only limited to mRNA therapeutics already identified by the cross-industry team, but also to include how these challenges could potentially negatively impact companies and the RNA industry. It sets out what the team is hoping to achieve via this collaboration, both in terms of outputs and benefits to the industry.
IT can be simple: Using analogies to facilitate collaboration on the IT challenges of supplying cell and gene therapies
Cell and gene therapies (CGTs) are medicines with enormous potential to create personalized therapeutics for patients with diseases that were once untreatable. However with these opportunities come challenges. One is how IT and CGT teams understand each other’s needs and challenges – only once this knowledge gap is bridged will CGTs be produced and administered commercially. This paper uses analogies to help specialists from CGT and IT to discuss and understand the key issues in commercializing CGTs and important aspects of IT systems and infrastructure. The analogies also reveal those differences in a relatable way that stimulates creativity and joint problem solving, which are critical in this fledgling but fast-growing industry.
