Quality Risk Management in Cleaning Validation Degradation Studies

The beta-lactam antibiotic family contains numerous compounds divided into at least five classes that share a common beta-lactam ring structure. As with other high potency active pharmaceutical ingredients (APIs), beta-lactam antibiotics can produce adverse reactions in patients and manufacturing operators. Due to the potential side effects of exposure to these compounds, an effective cleaning process is crucial to ensure there is no contamination in subsequent batches manufactured. Additionally, if the target residue can be broken down or degraded, the risk to subsequent batches is further reduced.
The primary variables considered during cleaning process development are Time, Action, Cleaning Chemistry, Concentration, and Temperature. Some manufacturing environments may have engineering or regulatory restrictions that limit one or more of these parameters. Previous studies have assessed degradation of beta-lactams at elevated temperature using formulated alkaline detergents. This presentation details a case study of an instance where limits on cleaning process temperature and available cleaning chemistries created complications in development of the cleaning process. Degradation profiles for several target antibiotic compounds processed in common equipment were characterized via HPLC. Existing methods were investigated and modified based on scouting study results; details of study design, controls, and results will be discussed to provide a wholistic view of the study.
Using a risk-based approach, the data collected was used to identify cleaning parameters that could not only provide effective and rapid cleaning of residues but would also effectively degrade the target molecules.
