Hello good people of the world! Another short post today, this one on the revision to EudraLex Volume 4 (GMPs) dated 13 August 2014. The revision is here. A short revision, the changes include updates to Chapter 3 (Premises and Equipment) and Chapter 5 (Production) around prevention of cross-contamination and qualification of suppliers.
Of note is the increased guidance around the use of quality risk management principles.
The revision will come into affect in March 2015.
What do you think of these changes? How will you adjust your quality program, if at all?

Hello, good people of the world! Recovery studies are studies to support surface swab processes. They typically involve “spiking” a “coupon” made from a particular material with a known amount of the contaminate you’re interested in, and then systematically quantifying the amount recovered via the swab process.
You’ll need to perform recovery studies for all product-contact materials you have in your manufacturing process. These typically include 316L stainless steel, PTFE, glass, etc.
Hello, good people of the world! If you know me, then you know I’m into “metrics” – ways to evaluate the health of a system or process quantitatively. We know finding and correctly interpreting the “right” metrics is not trivial, and looking at the “wrong” metrics can do more harm then good.
