Navigating uncertainty in pharmaceutical manufacturing: The critical role of technology transfer

The pharmaceutical manufacturing landscape is in a period of transition. Some of the changes reflect advances in science and technology that will bring innovative therapies to patients more quickly. Others arise from geopolitical tensions, regulatory changes, and unpredictable market shifts that contribute to a climate of uncertainty that can impact production, development timelines, and market stability.

In this changing environment, technology transfer is a pivotal navigational strategy, as it enables pharmaceutical companies to adapt quickly to changes in demand, regulatory policies, or market dynamics. Efficient technology transfer helps maintain product quality, protect intellectual property, manage costs, and scale operations, thereby ensuring that companies can respond effectively to new opportunities or challenges, maintain competitive advantage, and ensure uninterrupted supply of medications to patients.

In this first part of a two-part blog series, we explore the critical role of technology transfer in ensuring seamless production and maintaining competitive advantage. The second part of our series explores how strategic partnerships can mitigate technology transfer challenges and enhance operational resilience.

Understanding technology transfer and its significance

Technology transfer is the systematic movement of scientific methods and manufacturing processes from development to production or between sites, ensuring product consistency, quality, and regulatory compliance. This process is critical for producing pharmaceuticals safely and cost-effectively across various locations and scales, maintaining project timelines, and facilitating the seamless scale-up of new drugs and therapies. It ensures that innovative treatments reach patients promptly. Necessary during transitions such as scaling from clinical to commercial volumes, optimizing capacity between sites, or changing between CDMO partners, technology transfer demands detailed planning, comprehensive documentation, and rigorous validation to meet original product specifications and quality attributes.

Enhancing supply chain resilience

Effective technology transfer also plays a vital role in enhancing supply chain resilience by ensuring the robust sourcing of raw materials and packaging components. It supports detailed vendor management, crucial for maintaining quality across global supply networks. In logistics, the transfer of manufacturing processes includes critical shipping protocols and optimized route planning to ensure that clinical trial materials and finished products are delivered under the right conditions, preserving their integrity and efficacy. These aspects are crucial for adapting to the fast-paced and often unpredictable pharmaceutical market, ensuring that operations remain agile and responsive to any shifts in demand or regulatory changes.

Tech transfer challenges: Considerations for OSDs, biologics, and advanced therapies

Oral solid dosage (OSD), biological, and cell and gene therapy products each present unique challenges in technology transfer. For small molecule OSDs, the primary challenges revolve around achieving consistent batch reproducibility and maintaining formulation stability, particularly when active pharmaceutical ingredients (APIs) are sensitive to environmental variables like humidity and temperature. Critical factors include the precise replication of process parameters that influence physical properties of the tablets or capsules, such as hardness and dissolution rate. Additionally, ensuring the uniformity of particle size distribution during milling or granulation is essential, as it directly affects the compaction and dissolution profile of the final product. In multipurpose facilities, stringent controls are required to prevent cross-contamination between products, necessitating thorough cleaning and validation processes.

With respect to biologics, the manufacture of these products involves complex biological processes that are sensitive to slight changes in process conditions. A key technical hurdle is the control of the bioreactor environment during scale-up, which can drastically affect the quality of the product. Scaling up cell culture processes while maintaining the integrity and functionality of proteins, which can be affected by changes in pH, temperature, or oxygen levels, requires meticulous control over bioreactor conditions, as well as rigorous optimization of media and feed strategies to ensure consistent quality and yield throughout the production scale.

The robustness of the purification steps must also be ensured to prevent the loss of yield and product purity. Additionally, biologics are susceptible to variations in post-translational modifications, which can impact the efficacy and safety of the final product. The purification process also needs to be finely tuned to ensure product purity and yield, which can be particularly challenging during scale-up.

The complexities of tech transfer extend into the domain of cell and gene therapies (CGTs), where the challenges are uniquely stringent due to the nature of the products involved. These therapies demand an exceptionally high degree of precision in process replication, with strict controls over environmental variables to maintain the viability and functionality of live biological materials. Equipment and facility differences necessitate careful calibration and compatibility checks, and maintaining high standards of quality control and training for new personnel are vital. The scale-up from research and development to commercial production must not only preserve the therapeutic qualities but also ensure the consistent quality and efficacy of larger production volumes.

Assessing the quality and potency of CGTs requires robust analytical methods. As processes are transferred to different manufacturing sites, these methods must be carefully adapted and validated to ensure they remain effective. Moreover, tech transfer for CGTs poses additional challenges due to their unique and complex manufacturing processes that often lack the standardization seen in more traditional biologics. Effective communication and detailed documentation are crucial for smooth coordination between teams, while managing the supply chain involves ensuring the availability and quality of materials and handling logistics efficiently. Protecting intellectual property and maintaining confidentiality throughout the process are essential. Effectively addressing these challenges is vital for safeguarding the integrity of CGTs as they reach patients.

Ensuring regulatory compliance

OSD, biological, and CGTs must adhere to rigorous regulatory standards set by authorities such as the FDA and EMA. This involves detailed documentation of every aspect of the manufacturing process, from raw material sourcing to final product testing, to demonstrate compliance with Good Manufacturing Practices (GMP). Maintaining regulatory compliance during the technology transfer process is essential for accelerating smooth market entry, safeguarding product quality and safety, and ensuring that the product remains consistent across different manufacturing sites, which is crucial for maintaining the trust of healthcare providers and patients. The key regulatory considerations include:

  • Documentation and data Integrity. Providing comprehensive and accurate documentation is essential for regulatory compliance. Regulators require detailed records of batch processing, quality control results, and validations to verify that the manufacturing process is controlled and consistent with approved standards.
  • Standardized procedures. Regulators mandate that products are manufactured under standardized conditions to guarantee consistent quality. Any deviations from these standardized procedures could lead to non-compliance, potentially resulting in product recalls or regulatory sanctions.
  • Skilled and trained staff. Properly trained staff are critical for maintaining compliance. They must be well-versed in regulatory standards and capable of implementing these standards in their daily operations. Particularly for CGTs, where regulatory guidance is continually evolving, partnering with experts who are abreast of the latest changes is crucial. These experts can provide invaluable insights into strategic compliance planning and operational adjustments required to navigate the shifting regulatory requirements.
  • Scale-up reliability. Scaling up manufacturing processes introduces increased risks of deviations, which can compromise product quality and safety. Regulatory compliance requires that the product, regardless of scale or manufacturing site, adheres to the same quality standards established for the originally approved product.
  • Validation and quality assurance. Extensive validation studies are required to prove that the process remains under control and produces a consistent product at different scales and locations. For OSD, this might include validation of the mixing and compression processes. For biologics, validation efforts focus on critical aspects like cell line authenticity, media preparation, and the efficiency of purification techniques. For CGTs, this might include additional considerations such as the validation of viral vector titration methods and cell viability assays.
