Transitioning to continuous manufacturing for commercial biologics production

Transitioning to continuous manufacturing for commercial-scale biologics production represents a significant – but highly beneficial – shift in biomanufacturing strategies. This approach not only promises reduced costs, enhanced efficiency, and productivity, but also ensures consistent product quality ¹.

As part of this three-part blog series, we’ve previously covered the current issues faced in biologics production, and how continuous manufacturing helps to address these. In this final blog of our series, we delve into the steps required to transition from traditional fed-batch processes to continuous manufacturing, focusing on feasibility, commercial process development, and process validation.

Assessing feasibility

The first step in transitioning to continuous manufacturing is a thorough 3-month feasibility assessment. This involves evaluating the existing fed-batch process and identifying potential challenges and opportunities for continuous operation. Just – Evotec Biologics leverages its extensive expertise in continuous manufacturing to conduct detailed feasibility studies, which include:

• Cell line assessments: We run ‘mock perfusion’ cultures in scale-down models with existing or new cell lines and assess growth, productivity, and product quality.
  
  
• Verification at 3L bioreactor scale: The most promising cultures from the cell line assessments are re-run at the 3L scale and the perfusate used to screen downstream platform conditions using high-throughput technologies.
  
  
• COGM modeling comparison: Our experts compare data from the fed-batch performance with those generated during the feasibility study. This allows for an evaluation of the COGM benefits of switching to our continuous manufacturing platform.

The COGM models used in our feasibility studies are based on Net Present Costs (NPC). NPC calculations estimate cash flows by calculating operational costs and discounting over time using a cost of capital parameter ². We use these models to compare the COGM for continuous manufacturing with existing fed-batch processes, across different post-launch demand situations. Continuous manufacturing in J.POD^® facilities typically show lower operational costs, irrespective of production rates, due to our flexible facility design ².

Commercial process development

Once feasibility is established, the next step is to develop a robust, scaled-up commercial process. This involves:

1. Establishing a full 25-day end-to-end continuous manufacturing process: Establishing a continuous manufacturing process and evaluating robustness over a 25-day process, to ensure the biologic’s product quality attributes (PQAs) are maintained for the duration of the run.
   
   
2. A 1000-L engineering run: At our innovative cGMP facility , a commercial-scale run is conducted to demonstrate process efficacy
   
   
3. Clinical manufacturing runs: Supply subsequent clinical trials. Material is taken from these runs to generate and qualify the reference standard and perform stability studies on the drug substance (DS), ensuring regulatory compliance and future commercial success

 

During this development stage, we ensure the process is robust and can be seamlessly scaled up to meet commercial production demands. Our J.POD^®  facilities are designed to be highly adaptable, and enable a flexible process that can quickly adjust to changing market demands. Working together with our partners, we refine the continuous manufacturing process to maximize yield, productivity, and product quality.

Process validation

The final step in the transition is process validation. We perform process characterization, process validation and other Biologics License Application (BLA)-enabling studies. These include facility risk assessments, DS freeze/thaw studies, as well as shipping validation assessments.

These studies are critical for regulatory compliance and ensure consistent product quality ³. Ensuring the process meets all regulatory requirements, Just – Evotec Biologics has extensive experience in navigating regulatory landscapes, facilitating a smoother approval process.

Step into the new era of biologics manufacturing

Transitioning to continuous manufacturing is a transformative step for commercial biologics production. It offers significant benefits, including cost reduction, enhanced efficiency, and improved product quality. The additional advantage of our short feasibility studies is that they allow for the potential benefits of transitioning to be evaluated prior to committing to a full transition, substantially reducing risks.

In the dynamic world of biopharmaceuticals, cost efficiency is a critical factor, especially for start-up companies navigating the complex landscape of drug development. Continuous biomanufacturing is an innovative approach that has garnered significant attention for its potential to significantly reduce the cost of commercial biologics. Less often discussed, however, is the potential for continuous biomanufacturing platforms for first-in-human (FIH) clinical trials. This method not only streamlines the production process but also offers substantial savings during the manufacture of material intended for early phase antibody development, making it an attractive option for emerging biotech firms.

 

What is Continuous Biomanufacturing?

Continuous biomanufacturing is a process where the production of biopharmaceuticals occurs in a seamless, ongoing manner, as opposed to traditional batch manufacturing, which involves discrete, separate production cycles. This continuous approach leverages advanced technologies and automation to maintain a steady flow of production, ensuring consistent quality and efficiency.

 

Cost Efficiency in Early-Stage Clinical Trials

One of the most compelling advantages of continuous biomanufacturing is its ability to produce large quantities of biopharmaceuticals in a single run. This is particularly beneficial for early phase clinical trials, where the initial supply can often be enough to cover subsequent Phase 2a and Phase 2b clinical studies. Here’s why emerging biopharmaceutical companies benefit:

1. Elimination of Additional Batches: Traditional batch manufacturing often requires multiple production runs to meet the demands of Phase I and II clinical trials. Each additional batch incurs significant costs, including raw materials, labor, and quality control. Continuous biomanufacturing, however, can produce a large enough supply in one go, eliminating the need for these extra batches.
   
   
2. Consistent Quality: Continuous processes are designed to maintain a high level of consistency and offer more levers to tightly control critical quality attributes than fed-batch processes. Supplying multiple clinical trials from the same lot of material ensures a perfect level of consistency which is crucial for regulatory approval and patient safety, further streamlining the development process.
   
   
3. Time Savings: By producing all necessary material in one continuous run, companies can significantly reduce the overall time required to manufacture the material they need for clinical trials. They avoid the challenge of finding available slots in their CDMO’s production schedule. This accelerates the overall timeline for clinical trials, allowing for faster progression through the development pipeline.

 

Financial Impact for Start-Ups

For start-up companies, the financial implications of continuous biomanufacturing are profound. The cost savings from eliminating additional batches can amount to millions of dollars. These funds can then be redirected towards other critical areas of drug development, such as:

1. Research and Development: Investing in expanding the pipeline of new candidate biopharmaceuticals. 
   
   
2. Clinical Trials: Initiating additional clinical studies for other disease indications. 
   
   
3. Extending the funding runway: Providing the company with the longest possible time before it needs to raise additional funding.

From Batches to Brilliance: The Benefits of Continuous for Commercial Manufacturing

As we covered in the first blog of this series,  biotherapeutics sponsor companies face numerous challenges in process development and manufacturing. This largely comes down to the overwhelming reliance on fed-batch processes in the biologics industry, which bring lengthy production timelines, process risks, and supply chain vulnerabilities. These issues contribute to the high cost structure of biologics and limit the accessibility of these vital therapies worldwide.

Continuous manufacturing is a rapidly emerging alternative production process to fed-batch processing. Biological products are produced in an uninterrupted flow, resulting in a steady and consistent output of product. This approach addresses many of the challenges with fed-batch systems, including: 

• Reduced process costs and lower cost of goods manufactured (COGM)
• Scalability and adaptability to fluctuating demands
• Fewer process and scalability risks

Read on as we explore these benefits of continuous manufacturing for commercial manufacturing, describing how they can address the high cost structure associated with biologics, and help to meet the rising global demand for these life-saving therapies. 

 

Cost reduction

Continuous manufacturing can reduce the COGM by up to 75% compared to traditional fed-batch processes (1), while also achieving 10-fold higher productivity (Figure 1). 

Figure 1: Productivity of a fed-batch process compared with a continuous approach. 

 

This is partly achieved through workflow automation, which minimizes labor costs while improving production efficiency (Figure 2). Additionally, compared with fed-batch units that require large facilities to store product intermediates, continuous operations are highly intensified and have a much smaller facility footprint, further reducing operational costs. Continuous operations also enable manufacturers to optimize resource use and reduce waste, leading to additional cost savings. 

Figure 2: Unit operations and labor resources needed to run a continuous process compared to traditional fed-batch process

 

Scalability and adaptability

A continuous approach allows for a much more agile process, driven by greater scalability and adaptability. For instance, J.POD^® biomanufacturing facilities from Just – Evotec Biologics support throughput from less than 10 kg to over 2,000 kg per year of protein-based biologics including mAbs and biosimilars. Production can be rapidly scaled up by increasing bioreactor numbers and extending run times with intensified continuous manufacturing technology. This enables manufacturers to adjust production levels quickly in response to market demand. 

Figure 3: How Just – Evotec Biologics’ platform steady-state intensified continuous manufacturing process can be scaled

 

Reduced risk

Continuous manufacturing reduces risks by ensuring consistent product quality. A DoE approach can be used to fine tune product quality attributes (PQAs) during development and advanced monitoring in production can maintain process consistency. This consistency is crucial for reducing regulatory risks and ensuring the efficacy and safety of biologics. 

This innovative manufacturing approach also enhances supply chain and financial security. With a smaller facility footprint and reduced operational costs, the financial risk for sponsor companies is substantially reduced. The modular design of facilities like J.POD allows for rapid deployment and scaling, mitigating geopolitical disruptions and financial risks associated with traditional fed-batch processes.

The Biologics Bottleneck: How Conventional Manufacturing Technologies Limit Access

Over the past two decades, biotherapeutics, particularly monoclonal antibodies (mAbs), have transformed the therapeutic landscape for a range of prevalent health conditions, from autoimmune diseases to cancers. It’s also been estimated that some 7,000 rare disease indications could be addressed with biotherapeutics ⁽¹⁾. However, while biologics have shown remarkable efficacy in clinical settings, access to these therapies remains a significant challenge globally.

Most biologics developers rely on fed-batch systems for bioproduction. However, this approach brings several key challenges that create risks and inefficiencies in the production pipeline, including:

• High manufacturing costs
• Difficulty in adapting to demand
• Expensive and risk-prone commercial development process

In this blog, we’ll explore these major factors influencing the supply and access of commercial biologics, before highlighting how adopting a continuous manufacturing approach can address these challenges.

Challenges in biotherapeutics supply and access

High manufacturing costs

Fed-batch manufacturing involves discrete unit operations where production occurs in separate, sequential steps. Each step must be completed before the next one begins. This means large volumes of intermediates must be stored, which requires a substantial facility footprint.

Running these large-scale facilities is expensive and contributes to the high costs of manufacturing. Additionally, fed-batch processes often require significant manual input, needing large teams of operators for their execution, increasing costs further. As a result, fed-batch facilities run at a higher operational cost compared with continuous bioprocessing units.

Difficulty in adapting to demand

It’s challenging for biologics developers to accurately predict the take-up and global demand for a biologic, especially during early production phases. If demand is too low, it can lead to sponsors paying out for idle manufacturing capacity. Should demand be higher than forecasted, sponsors run the risk of underproduction, causing shortages and patients going without medicines.

Further adding to this problem, fed-batch processes rely on large-scale stainless-steel units for commercial supply that are expensive and time-consuming to build. This creates inflexibility, bringing difficulties in adapting fed-batch units to fluctuating demands. This scenario was experienced by the developers of rheumatoid arthritis therapy Enbrel^®. During times of increased demand, such as when new indications were approved or patient populations grew, inability to rapidly scale up production of their fed-batch process caused serious supply constraints ⁽²⁾. 

Expensive and risk-prone commercial development process

Fed-batch biomanufacturing processes face significant risk when it comes to scaling up production, especially for sponsors moving from clinical trials to commercialization. This can limit the ability of manufacturers to meet global demand.

Fed-batch processes must be scaled up by a factor of 5 to 20-fold in order to meet commercial demand, because of the inefficiency of the process.

Scaling up in this way creates the following risks:

• The large-scale process might not replicate the smaller-scale process performance
• Product quality attributes (PQAs) might change at increased scale
• A limited number of large-scale facilities exist worldwide, causing major supply issues during increased production demands

A better approach to biologics manufacturing

Biologics provide life-saving treatments, but access and supply have been limited due to their high cost structure, inflexible production processes, and unpredictable demand. Continuous manufacturing addresses these challenges by offering a more agile, cost-effective, and stable production process.

This approach involves raw materials being continuously fed into the bioprocessing system, while products are continuously yielded. By automating workflows and maintaining a steady state of operation, companies can improve scalability, adaptability, productivity, and consistency. Companies that have started their clinical journey with a fed-batch process should consider converting to a continuous manufacturing platform before commercialization to take advantage of these benefits.

Very Large-Scale (VLS) production facilities have traditionally been used for the commercial supply of biopharmaceuticals. Some commentators  argue that there is no need to break with this orthodoxy. Yet many sponsor companies and CDMOs are making a concerted effort to establish continuous drug substance manufacturing. In this blog article we examine six reasons that might explain this phenomenon.

 

Why are so many innovator companies and contract manufacturing organizations making a concerted effort to establish continuous drug substance bioprocesses? 

Historically the biopharmaceutical industry has relied on Very Large-Scale (VLS) production facilities for commercial supply. Yet there are increasingly frequent calls for innovation in antibody manufacturing¹ backed by industry consortia like NIIMBL² and the BioPhorum Operations Group³. Let’s explore some of the reasons why:

 

1. Productivity: Continuous manufacturing allows significantly higher productivity than fed-batch manufacturing in VLS facilities. The current state of the art for cell line development in fed-batch processes is 8+ g/L compared with equivalent titers of 30+ g/L in perfusion bioreactors⁴. This allows antibody production in smaller, more efficient and agile facilities that deliver extremely low Cost of Goods Manufactured (COGM) while avoiding upfront scale-up costs and risk⁴.

 

2. Production Capacity: Continuous manufacturing facilities, such as Just - Evotec Biologics J.POD^® facilities, can deliver 2,000+ kg of drug substance each year and are ideal for many biotherapeutics including monoclonals, bispecific antibodies and Fc-fusion proteins. VLS facilities are designed to accommodate a small number of high-volume products.

 

3. Agility: Demand for biologics fluctuate throughout their lifecycle and is notoriously difficult to predict. This is especially true during both the product introduction phase and at the end of the lifecycle as sales are eroded by competing products. 

Commercial demand for Enbrel^®, for example, was so great when it was launched that patients’ access was restricted until the supply chain recovered⁶. In contrast, Biogen started investing $2 billion in VLS manufacturing at Solothurn, Switzerland in 2015⁷ to manufacture Aduhelm^®. The product was initially approved in June 2021 only for the company to announce it would halt sales due to a realignment of its Alzheimer’s disease franchise in January 2024⁸ leaving the company to find a new use for their facility.

Continuous biomanufacturing facilities comprising of intensified single-use platforms with production-on-demand cleanrooms are extremely agile and can be built in under two years thanks to parallel construction techniques and reduced need for WFI, SIP and CIP utilities. This contrasts with stainless steel VLS facilities which take over 4 years to bring online⁹. They require significant amounts of capital engineering leading to high depreciation costs that must be ultimately borne by the facility occupants.

 

4. Supply Chain Security with Distributed Manufacturing: Global drug shortages have put the spotlight on supply chain security in the pharmaceutical industry. These have become vulnerable for several reasons including an over-reliance on small numbers of centralized facilities in a limited number of geographical regions¹⁰.

Global networks of distributed manufacturing facilities mitigate these risks and ensure the needs of local patient populations are met despite a range of scenarios that can evolve during epidemics and pandemics. This avoids an excessive reliance on non-governmental organizations corralling manufacturers to produce specific medicines or demanding elusive new business model solutions that may or may not expand access. With the aim of increasing medicine supply chain security for their population, policymakers such as the French government have chosen to invest in industrial sovereignty in the healthcare sector. The need for this was emphasised by the health crisis caused by the COVID-19 pandemic¹¹.

 

5. Process Portability: VLS production processes suffer from having low process portability. Transferring between these facilities is neither fast, inexpensive or assured of success. The cost of transferring processes into a new VLS facility runs into tens of millions of dollars. Consider the bill for new consumables alone or the cost of packing chromatography columns with diameters exceeding 1.4 m with Protein A resins. Very few VLS facilities are identical despite what commentators would like us to believe.

In practice, these fixed pipe facilities must be re-engineered for each new unique product that is transferred into the asset. The sponsor must pay these CAPEX costs but also the cost of pilot and engineering runs required to mitigate scale-up risks. 

Just – Evotec Biologics provide true process portability by offering partners access to its technology platform under a licensing agreement so that sponsor companies can bring their products and processes in-house and fully under their control.

 

6. Sustainability: Pharmaceutical and large biotechnology companies are increasingly cognizant of their environmental impact and are setting ambitious sustainability goals. Intensifying antibody production through adopting continuous manufacturing will allow these firms to manufacture their antibody products with fewer of the earth’s resources¹². In contrast, VLS facilities require large amounts of carbon-intensive concrete during their construction phase. During operations they need significant amounts of energy to generate super-heated steam for SIP systems and highly purified water-for-injection needed for flushing cleaning solutions from stainless steel tanks.

With high attrition rates of mAbs in early phase clinical trials, it is becoming increasingly challenging for biopharmaceutical companies to rapidly deliver high quality therapeutic mAbs using conventional antibody screening and fed-batch bioprocessing methods. This is why new Quality by Design (QbD) approaches such as using in silico AI and ML platforms to discover and optimize mAb sequences, high-throughput screening, and continuous intensified manufacturing processes such as those used at Just- Evotec Biologics are critical for enabling a paradigm shift in reducing attrition rates.

As detailed in this article, optimizing mAb design, using automated, miniaturized screening, and minimizing time in culture can deliver high-quality mAbs for FIH trials in rapid response times of around 12 months. In the future using this approach could expand access to life changing treatments, as well as support a rapid response to global health emergencies.

OncoResponse is a biotech company that specializes in immuno-oncology, the science of using the body’s own immune system to fight cancer. The company uses insights from patients who have exceptional responses to cancer treatments to create new therapies. OncoResponse works closely with MD Anderson Cancer Center at the University of Texas, one of the world’s leading cancer research institutes, to use a unique technology that finds and develops new antibodies that target the immune cells in the tumors.

The company’s most advanced therapy, OR502, is an antibody that blocks a protein called LILRB2 that suppresses the immune system. OR502 restores the immune system’s ability to attack the cancer cells and is currently being tested in clinical trials.

OncoResponse partnered with Just-Evotec Biologics on OR502 to develop a manufacturing process that would supply their Phase 1 clinical trials.

The partnership was kicked-off by OncoResponse providing several variants of the OR502 antibody. Just-Evotec Biologics used its Abacus™ predictive computational tool from its J.MD™ Molecular Design toolbox to evaluate the manufacturability and stability of the different variants allowing OncoResponse to select a lead candidate with optimal manufacturability properties.

Just-Evotec Biologics then developed a cell line with its J.CHOTM High Expression System to produce OR502 in its continuous biomanufacturing platform. This system utilizes CHO-K1 host cells, transposon-based expression vectors and proprietary cell culture media. The company’s scientists further developed the process and successfully scaled it up in their J.PLANT™ Seattle GMP manufacturing facility at the 500-L bioreactor scale. This allowed operational teams to manufacture material for the first-in-human trial and provide the necessary CMC data for OncoResponse’s Investigational New Drug submission to the FDA. The CMC development from ordering DNA for transfection through to the shipment of drug substance to the fill finish site took just 11 months.

In November 2023, OncoResponse announced the first person to receive OR502 has been dosed in a Phase 1/2 trial. The trial aims to test the safety, tolerability, and initial anti-cancer effects of OR502 alone and in combination with anti-PD-1 in people with advanced solid tumors. OR502 clinical studies are being conducted with support from the Cancer Prevention Research Institute of Texas (CPRIT) DP230076.

“Our launch of this trial in cancer patients shows our ongoing dedication to developing treatments that can enhance the outcomes for people with cancer,” said Clifford Stocks, CEO of OncoResponse.
