FDA Modifies cGMP Guide – New Text Published

 
On 4 December 2007 the US Food & Drug Administration (FDA) has published changes to the cGMP Guide. We already reported about the planned measures in our News from 25 October 2007. They were also presented by Fred Blumenschein from the authority on the occasion of the 2nd European GMP Conference end of June in Heidelberg, Germany, which was organised by the ECA and the European QP Association.

With the announcement of the new text the FDA also withdrew the "proposed rule" from 1996. This proposed rule contained major modifications of the cGMP Guide. However, a FDA working group found out, that the planned changes are not compliant with the authority's new risk based approach for the 21st Century any more.

On the one hand the FDA intends to substantiate certain requirements with the changes. On the other hand it wants to accomplish an incremental approach to modernisation of cGMP. The modified guide is then supposed to comply with the FDA initiative for the 21st Century.

For instance, one change affects the area "Aseptic Processing". With this regard the FDA has published the Guidance for Industry "Sterile Drug Products Produced by Aseptic Processing" in September 2004. This document was developed following an analysis of the GMP Harmonisation Analysis Working Group. One part of the analysis was a comparison with the EC GMP Guide. Now the FDA has implemented the necessary concretion in the cGMP Guide and has matched it more to the September 2004 Guidance. The new text is not surprising, because it mainly contains requirements that have been interpretations of the authority for several years. However, now the FDA also established the legal scope.

The changes listed below become effective on 17 April 2008. Comments can be provided until 19 February 2008. If there are no essential comments that will prevent the authority from implementing the new content, the FDA will issue an announcement in the Federal Register on 18 March 2008 which will confirm the mentioned due date.

§ 211.103 Calculation of yield.
Actual yields and percentages of theoretical yield shall be determined at the conclusion of each appropriate phase of manufacturing, processing, packaging, or holding of the drug product. Such calculations shall either be performed by one person and independently verified by a second person, or, if the yield is calculated by automated equipment under § 211.68, be independently verified by one person.

■ 13. Section 211.110 is amended by revising paragraph (a) introductory text and by adding paragraph (a)(6) to read as follows:
§ 211.110 Sampling and testing of in-process materials and drug products.

§ 211.182 Equipment cleaning and use log.
A written record of major equipment cleaning, maintenance (except routine maintenance such as lubrication and adjustments), and use shall be included in individual equipment logs that show the date, time, product, and lot number of each batch processed. If equipment is dedicated to manufacture of one product, then individual equipment logs are not required, provided that lots or batches of such product follow in numerical order and are manufactured in numerical sequence. In cases where dedicated equipment is employed, the records of cleaning, maintenance, and use shall be part of the batch record. The persons performing and double-checking the cleaning and maintenance (or, if the cleaning and maintenance is performed using automated equipment under § 211.68, only the person verifying the cleaning and maintenance done by the automated equipment) shall date and sign or initial the log indicating that the work was performed. Entries in the log shall be in chronological order.
