The report introduces the concept of commensurate monitoring. If you have an RABS with gloves that are only changed quarterly, your APS must be long enough to cover the worst-case glove integrity degradation over time. Don't treat the new PDA TR1 as a reading assignment for the validation team. Treat it as a risk assessment workbook .

The new guidance insists that media fills (APS) are not just a regulatory hurdle to cross every six months. They are a living dataset. The report now asks: Are you trending your APS data over time? Are you using statistical process control (SPC) to detect drift before a failure occurs? pda tr1

Here is what you need to know to stay audit-ready. The most significant change in the 2022 revision is the explicit move toward Continuous Process Verification (CPV) . The old TR1 allowed for a bracketing approach where you validated a few worst-case scenarios and called it a day. The report introduces the concept of commensurate monitoring

If you use nitrogen backfill, the report suggests evaluating the sterility of that gas path in your worst-case load configuration. This is a common regulatory citation that TR1 2022 tries to fix. The report is explicit: EM data does not replace APS. Conversely, if you have great EM but fail an APS, the APS overrules the EM. Treat it as a risk assessment workbook

But here is the catch: If your current aseptic processing strategy is still based on the 2007 version, you are already behind.
