• To describe a comprehensive testing strategy for contamination control.
• To ensure the safety and quality of final oncolytic virus products.

Main Methods:

• Review of current regulatory guidelines for biological product manufacturing.
• Development of a multi-stage testing strategy.
• Inclusion of testing protocols for cell lines, virus banks, harvests, and purified products.

Main Results:

• Identification of critical control points for contamination in oncolytic virus production.
• A structured testing approach is proposed to mitigate risks.
• Regulatory compliance is emphasized throughout the manufacturing process.

Conclusions:

• Implementing a robust testing strategy is vital for oncolytic virus safety.
• Adherence to regulatory guidance ensures product quality and patient safety.
• Continuous monitoring and testing are necessary for reliable oncolytic virus therapeutics.
