Transforming tablet production

Continuous direct compression at the Medicines Manufacturing Innovation Centre

Summary

Ageing populations, rising healthcare costs, drug development costs, and the need to make manufacturing processes more sustainable are just some of the challenges facing the pharmaceutical industry today.

The Medicines Manufacturing Innovation Centre, a collaboration between CPI, University of Strathclyde, UKRI, Scottish Enterprise, AstraZeneca and GSK, has pioneered a new, faster, more efficient and sustainable tablet production process to ultimately benefit those most deserving – patients.

A Grand Challenge for Pharma

Medicines manufacturing has not changed significantly in over 40 years. At the same time, the rising cost of global healthcare systems means that the processes that deliver medicines to them need a new approach.

Current medicines manufacturing involves inefficient traditional large-batch methods that are resource and time-intensive. Meanwhile, new medicines are trending towards more complex, stratified products that need to be produced in lower volumes.

The challenge for the pharmaceutical industry is to achieve greater efficiency and flexibility. The solution lies in Continuous Direct Compression (CDC).

Continuous direct compression

Continuous direct compression (CDC) of oral solid dosage medicine is a novel manufacturing method that aims to eliminate some of the cost and complexity of old traditional batch processes. It enables drugs to be developed and scaled up using much lower quantities of expensive and complex ingredients, facilitating rapid production of formulations at a range of scales. 

Shorter production runs enable pharma companies to respond more effectively to differing patient needs while simultaneously reducing the development burden and costs.

The CDC physical line we have developed is also digitally twinned. This means that the manufacturing process is digitally simulated to test its performance and efficiency. Using real-world data, scientists can better understand and optimise the process design. 

This twofold benefit of working with smaller batches and of design optimisation allows the pharmaceutical industry to make better-informed formulation choices and produce tablets in an energy and resource-efficient way. 

Our CDC offer

At the Medicines Manufacturing Innovation Centre, we are now offering a service to advance your CDC process development activities through the utilisation of our digital twin and physical access to our continuous direct compression line. 

The line is fully modular and vendor agnostic, enabling flexibility to your tabletting needs. Through this — CPI can fully support your CDC journey. 

As a client you can benefit from various offer levels:

Benefits of CDC

60 – 70% reduction in facility size

30 – 50% reduction in manufacturing costs

69% reduction in energy consumption

Putting CDC into action

Uptake of CDC in the industry has been relatively slow, with just 12 products known to be commercially available as of 2024. At the Medicines Manufacturing Innovation Centre, we have brought together industry, academia, healthcare providers and regulators to make this important new technology commercially viable. 

The team created a world-class demonstrator in a good manufacturing practice (GMP) environment to prove CDC principles at commercial scale, helping the industry to transition to continuous and minibatch manufacturing. The digital twin program takes the transition support even further. 

Together, they drive efficiency in pharmaceutical product development, as well as allowing for tailoring of medicines for specific patient groups.

This will support the industry to shift from traditional large batch manufacturing approaches – which are based on forecast demand so require large amounts of inventory – to continuous and mini-blend manufacturing.

The digital CDC platform will deliver:

Sustainability

Reduced starting materials, less waste and energy, and a smaller footprint, which results in a lower environmental impact.

Commercial advantage

Reduced development and manufacturing times gets products to market faster.

Product improvements

Increase in yield and consistency.

Reduced running costs

Less material waste.

Real-time monitoring

Enables early detection and prediction.

Faster processing time

Reduced from weeks to days.

Faster modelling time

Reduced from hours to minutes.

Regulatory compliance

Consistent manufacture of product that can be verified using real-time data.

Collaborating with CPI

At the Medicines Manufacturing Innovation Centre, we employ a collaborative operational model, which enables partners to join through a combination of direct funding and benefit-in-kind contributions towards resources or technology. 

Alongside our founding partners AstraZeneca and GSK, we’re delighted to have welcomed several new partners to the collaboration, including Pfizer, Siemens, Gericke, Applied Materials and DFE Pharma, who together bring a wide range of expertise to the project:

We are actively seeking new partners to maximise the impact of this innovative platform for drug manufacture, over a series of new projects

- Advancement / comparison in PAT technologies as a driver towards PAT robustness for continuous manufacturing 

- Delivery of co-developed CDC product development and regulatory best practice document / white paper 

- Sustainable tablet manufacture using Advance Process Control (and self-optimisation) as a control strategy 

- Actively bridge the core gap in skills and knowledge to provide the capability to develop new assets on this technology and demystify continuous manufacturing
