Optimising Cleaning Validation for Complex Product Lines
Pharmaceutical company with complex, multi-stage product lines
Unstable results in the cleaning validation of complex products led to inefficiencies and rising operating costs.
The challenge
The situation
The existing cleaning validation methods produced unstable results for complex product lines. This led to inefficiencies and rising operating costs, and the processes were not robust enough to ensure continuous compliance. A comprehensive redesign of the methods was needed.
Our approach
What we delivered
Method re-engineering of cleaning validation for the complex product lines
Evaluation and selection of method optimisation over alternative approaches
Coordination of implementation and revalidation activities across the affected lines
The outcome
Results & impact
EUR 180,000 cost reduction
Lower operating costs through the optimised method instead of costly alternatives.
Implemented within one year
Redesign and revalidation of the methods completed within one year.
No compliance deviations
Transfer into routine operation without open compliance points.
In summary
The manufacturer has a stabilised, more robust cleaning validation for its complex product lines, implemented within one year and with tangible cost relief.
