Application of novel Raman spectroscopy device and advanced data analytics to optimise viral vector production and design

There are two methods to optimise viral vector production, the first is to improve the micro-environment within the bioreactor and the second is to improve the design of the viral vector constructs. Both of these approaches have the potential to improve viral vector titres, product quality and enable easier scale-up. The first part of this project will focus on optimising the control of the bioreactor micro-environment as this is of paramount importance to ensure product heterogeneity remains within a predefined specification defined by commercial good manufacturing practice (GMP) operations. However, continuous online monitoring is available only for a small number of process parameters (i.e pH, temperature and DO2) in viral vector manufacturing.

Currently, the control of these bioreactor processes implements rudimentary and suboptimal control strategies that rely heavily on off-line data analytics and infrequent operator decisions. Machine learning techniques combined with advanced Process Analytical Technologies (PATs) such as Raman spectroscopy can enable real time predictions of key CPPs and CQAs. These real-time predictions can be combined with advanced feedback controllers that can be used to optimise process performance such as maximising viral titres and minimising manufacturing impurities such as empty capsids. Once the control algorithms have been developed, the second part of the project will be to modify the gene sequence of the cap or rep gens and evaluate how the design of these will improve clinical manufacturing processes within a well-defined and controlled bioreactor system.

The 2016 UK Roadmap Bio-design for the Bio-economy highlighted the substantial impact that synthetic biology can bring to the UK and global economies by developing: frontier science and technology; establishing a healthy innovation pipeline; a highly skilled workforce and an environment in which innovative science and businesses can thrive. Synthetic biology promises to transform the UK Bio-economy landscape, bringing bio-sustainable and affordable manufacturing routes to all industrial sectors and will ensure society can tackle many contemporary global Grand Challenges including: Sustainable Manufacturing, Environmental Sustainability Energy, Global Healthcare, and Urban Development. Whilst synthetic biology is burgeoning in the UK, we now need to build on the investments made and take a further lead in training next generation scientists to ensure sustained growth of a capable workforce to underpin the science base development and growth in an advanced UK bio-economy.
This training provided by this CDT will give students from diverse backgrounds a unique synthesis of computational, biomolecular and cellular engineering skills, a peer-to-peer and industrial network, and unique entrepreneurial insight. In so doing, it will address key EPSRC priority areas and Bioeconomy strategic priorities including: Next-generation therapeutics; Engineered biomaterials; Renewable alternatives for fuels, chemicals and other small molecules; Reliable, predictable, and scalable bioprocesses; Sustainable future; Lifelong health & wellbeing.
Advances created by our BioDesign Engineering approach will address major societal challenges by delivering new routes for chemical/pharma/materials manufacture through to sustainable energy, whilst providing clean growth and reductions in energy use, greenhouse gas emissions and carbon footprints. Increased industry awareness of bio-options with better civic understanding will drive end-user demand to create market pull for products. The CDT benefits from unrivalled existing academic-industry frameworks at the host institutions, which will provide direct links to industrial partners and a direct pathway to early economic and industrial impact.

This CDT will develop 80-100 next-generation scientists and technologists (via the funded cohort and wider integration of aligned students at the three institutions) as adept scientists and engineers, instilled with technical leadership, who as broadly trained individuals will fill key skills gaps and could be expected to impact internationally through leadership roles in the medium term. Importantly the CDT addresses key skill-gaps identified with industry, which are urgently required to create and support high value jobs that will enable the UK to compete in global markets. Commercialisation and entrepreneurship training will equip the next generation of visionaries and leaders needed to accelerate and support the creation of new innovative companies to exploit these new technologies and opportunities.

The UK government identified Synthetic Biology as one of the "Eight Great Technologies" that could be a key enabler to economic and societal development. This CDT will be at the forefront of research that will accelerate the clean growth agenda and the development of a resilient circular bioeconomy, and will align with key EPSRC prosperity outcomes including a productive, healthy and resilient nation. To foster wider societal impact, the CDT will expect all students to contribute to public outreach and engagement activities including: open days, schools visits, and science festival events: students will participate in an outreach programme, with special focus on widening participation.

This CDT will contribute to the development of industrial strategy through the Synthetic Biology Leadership Council (SBLC), Industrial Biotechnology Leadership Forum (IBLF), and wider Networks in Industrial Biotechnology and Bioenergy and Professional Institutes.
