Challenges Implementing AI

While the benefits of integrating AI in the pharmaceutical sector are substantial, several challenges necessitate careful consideration. The accessibility and quality of existing data may pose a hurdle, as AI systems heavily rely on FAIR datasets (Findable, Accessible, Interoperable, Reusable) for training and decision-making.⁶ Ensuring the availability of high-quality, relevant data is imperative for the successful implementation of AI in pharmaceutical manufacturing.

Additionally, there is a need for flexibility in incorporating new technology into organizational structures. This may pose a problem for legacy organizations in navigating existing frameworks, protocols, internal cultures, and other factors to seamlessly integrate AI technologies. Here, a strategic approach to change management and quality-by-design (QbD) is required to foster an environment that embraces the transformative potential of AI, ensuring a harmonious integration that maximizes the benefits while mitigating potential challenges.

Trends Shaping the Future of AI in Pharmaceutical Manufacturing

With projections of the AI in Manufacturing market indicating an explosive surge to $16.3 Billion by 2027 (with a remarkable annual growth rate of 47.9%)⁷, it is clear that AI is becoming increasingly pervasive in manufacturing. Let's examine several significant trends being leveraged in the field of pharmaceutical manufacturing.

1. Digital Twins in Pharmaceutical Manufacturing

Digital twin technology, in the context of pharmaceuticals, manifests as a virtual mirror of an entire production process or system. For bioprocessing, a digital twin transcends conventional modeling by encompassing the entire process from raw materials to a final product. This virtual representation spans the entire lifecycle of the manufacturing process, continuously updated in real-time through a sophisticated combination of simulation, machine learning, and plant data. The synergy of these elements positions digital twin technology as a powerhouse, driving unparalleled precision, quality, and efficiency in pharmaceutical production.

In the pharmaceutical industry, digital twin technology is harnessed to elevate and streamline existing production processes in real-time. By integrating real-time data and leveraging advanced analytical tools, pharmaceutical manufacturers can gain insights into every facet of the production cycle. This includes optimizing operational parameters, identifying potential bottlenecks, and enhancing overall process efficiency.⁸ 

However, implementing digital twins in an industrial, regulated environment can be challenging. From connecting to a variety of data lakes and cleaning data to ensure usability by both humans and machines, all the way to visualization, modeling, and exporting of key model outputs to various stakeholders. For this reason, the successful implementation of digital twins relies on subject matter expertise across multiple teams working synchronously to meet stringent engineering, regulatory, and cybersecurity requirements.⁹

2. Expectations for establishing product comparability after changes to manufacturing conditions introduced by the AI model, especially for biological products”

The demand for AI explainability has led to the emergence of alternative modeling approaches, incorporating fundamentally explainable components driven by the laws of physics or chemistry, such as hybrid modeling. These approaches serve as a strong complement to traditional data-driven modeling. The outputs of these hybrid models are directly connected to explicit engineering and scientific knowledge and allow stakeholders to “look under the hood” into the model decisions, making model-driven decisions easier to understand and interpret.

By adopting a proactive stance toward compliance, pharmaceutical companies can leverage the transformative power of AI while adhering to the stringent standards that govern the industry, fostering trust and reliability in their operations.
