Challenge
Adapting and validating a complex autoclave load for use in a second autoclave
To support business continuity at a pharmaceutical facility in Barcelona, QbD Group worked closely with engineering and production teams to adapt and validate a complex autoclave load for integration into a second unit.
The project involved optimizing load configurations, identifying process improvement opportunities, and ensuring the reliable transfer of sterilization parameters between autoclaves.
The validation had to cover a wide range of variables—different excipients, concentrations, solution volumes, and bottle quantities—to guarantee robustness, regulatory compliance, and reproducibility across diverse manufacturing conditions.
Approach
A multidisciplinary initiative to ensure successful autoclave load validation
QbD Group pinpointed key parameters affecting heat penetration and lethality in solution, using both historical data and physicochemical characteristics to guide the process.
Targeted Performance Qualification (PQ) assays were developed, and cross-functional coordination was implemented to align activities with strict project timelines.
In addition, QbD Group led data analysis and managed deviations, ensuring that the final technical report met scientific standards and was delivered on time.
Result
Measurable impact and long-term benefits
By leveraging QbD Group’s expertise, the client significantly improved the efficiency of their sterilization process. Our collaboration delivered the following results:
-
The autoclave load is now fully validated, with clear improvements over the original configuration.
-
The updated load accommodates higher validated solution concentrations and volumes, includes an additional excipient in the scope, and allows for a greater number of bottles per cycle—all without compromising sterilization performance.
-
These enhancements boost both process flexibility and overall manufacturing efficiency, supporting long-term operational resilience.
