Automation and single-use systems in cell & gene therapy manufacture: Realizing the potential

MullerKleinHeckmann

Desminopathies are diseases linked to mutations in the desmin gene. Although of monogenetic etiology, desminopathies are challenging and very intriguing from a gene therapeutic point of view as pathophysiology varies with different mutations. Animal models mirroring their distinct pathophysiologic mechanisms are still scarce. Recent scientific advances have revealed promising new therapeutic strategies. This editorial highlights the recent gene therapeutic approaches being tested in animal models for the treatment of desminopathies.

Automation and single-use systems in cell & gene therapy manufacture: Realizing the potential

Providing a critical overview of the sector’s commercial developments – M&As, licensing agreements & collaborations, financial results, IPOs and clinical/regulatory updates, with commentary from our Expert Contributors.

CELL THERAPY:

Organova has been busy for some time now developing 3D bio-printed tissues for use in screening drug candidates. The thesis being that Pharma can save dollars by adopting screens that provide greater ‘predictiveness’. It’s a tough business model. Cellular Dynamics International, now owned by FujiFilm, burnt through a great deal of money in its day trying to persuade Pharma to screen compounds with its cell lines. Organovo upped the ante, though, with its printing platform, creating 3D, multi-cellular aggregates, or ‘organoids’, which more closely resemble real tissue. The company announced a collaboration with Merck in 2015, giving Merck access to its human liver tissue platform for drug development. Now, Organovo has plans to transcend tools into the realm of therapeutics, and will bring its bio-printed tissue into the clinic, initially for liver disease. Ambitious? Absolutely, but it’s a small step towards realizing the big vision of artificial organ replacement.

GENE THERAPY:

This month illustrates the mixed fortunes of companies working in cell and gene therapy. Whilst Spark Therapeutics continues to roll out positive clinical data in the rare eye disease Leber’s congenital amaurosis-2, and Agilis Biotherapeutics announced authorization of a Phase IIb trial in the rare CNS disease aromatic-l-amino acid decarbolylase deficiency, there is less good news from Adverum, which announced a 1-year delay to its alpha-1-antitrypsin deficiency program due to manufacturing issues. Adverum uses a baculovirus-based AAV production system; whilst these systems are scalable, they can present problems with low yields and baculovirus stability. R&D in gene therapy is as healthy as ever, but manufacturing can often prove to be the Achilles heel for the field.

The Cell & Gene Therapy Manufacturing Pathway: Part 3

The quality attributes of advanced therapy medicinal products (ATMPs) that correlate with safety and efficacy in patients are determined not only by manufacturing process inputs such as starting and raw materials, but also by how the manufacturing process itself is designed and controlled. To ensure regulatory compliance, the manufacturing process should therefore be developed based on thorough characterization of the ATMP during all stages of process and analytical development; this ensures that the critical quality attributes that correlate with safety and efficacy are identified and that their specifications can be met during routine manufacturing. In the European Union, the regulatory approval of ATMPs for use in patients requires that data demonstrating their quality, safety and efficacy are submitted in dossiers to regulatory agencies for review. Indeed, such dossiers have a specific format that, in the case of quality data in particular, is informative for the manufacturing process development strategy. This manuscript describes how dossier requirements can be implemented into the design of industrialized ATMP manufacturing processes and fulfilled to enable effective regulatory submissions.

Automation and single-use systems in cell & gene therapy manufacture: Realizing the potential

The need for automation in cell and gene therapy manufacturing processes is primarily driven by the regulatory requirements for reproducibility, clinical need for consistent, efficacious therapies and commercial constraints of developing scalable, cost-effective processes. Automation has already played a pivotal role in healthcare manufacture, including that of successful vaccine production, however the role of automation continues to evolve and technologies and platforms are now emerging which succeed in expediting efforts in process development, facilitating high-throughput approaches, thereby effectively reducing the cost of development and time to market. Moreover, early integration of automation facilitates process transitions at later stages of clinical development and commercialisation. There is however genuine concern regarding the capital costs of developing an automated solution; a clear strategic decision needs to be made as to what point in the development pathway automation is introduced, and to what extent. Factored into this decision, also, is the nature of any solution, for example a turn-key automated system or a bespoke platform. Ultimately the extent and nature of any approach will depend on our level of process and product understanding; as this improves, we are likely to see a significant shift toward the adoption of automated solutions.

Automation and single-use systems in cell & gene therapy manufacture: Realizing the potential

Decentralized, or redistributed manufacture, is likely to be the manufacturing approach of choice for some cell- and gene-based therapies, in particular, personalized therapies. Such an approach will ultimately depend on the business model and will take into account the regulatory and supply chain factors. Advances in technology and integration of automated production platforms have demonstrated the potential for decentralized manufacturing, however there is a need to extend the scope of automation across the entire process including the cell isolation, distribution, tracking, administration, quality management systems and development of automated analytical techniques to facilitate real-time release. For decentralized manufacture to be successfully integrated for cell and gene therapy production, lessons from other accepted healthcare-associated models of manufacture can provide useful insights and perspectives to make informed decisions. Such models share similar characteristics to decentralized manufacture in that they are patient-specific and have a limited time-frame for administration. These existing approaches, which have successfully incorporated aspects of automation, can provide a blueprint for success and may expedite the decentralization of patient-specific cell and gene therapy manufacture.

The Cell & Gene Therapy Manufacturing Pathway: Part 3

PRODUCT & PROCESS UNDERSTANDING

[line]

With many cell therapy companies struggling to meet the manufacturing demands of large-scale commercial production, the industry is slowly moving towards implementation of “Quality-by-Design” principles to gain an understanding of the impact of critical process parameters on critical quality attributes of the product. However, this framework needs an upfront investment in time and resources (ideally during the discovery phase) and process and product development, which is not always an option. Ultra scale-down technologies, allow high-throughput experimentation with minimal material, providing an attractive option for cost-effective screening during the discovery phase. Given adequate characterization with respect to large-scale operations, these tools hold the potential to enable process development and application of “Quality-by-Design” principles to various cell manufacturing steps, especially those concerning downstream processing. This article discusses some of the key challenges faced in cell therapy manufacturing, and how ultra scale-down devices may be implemented as tools to address these.
