Notes on the FDA’s Draft Data Integrity and Compliance With CGMP Guidance for Industry

Having worked in the pharmaceutical industry where I’ve dealt with electronic systems, paper based systems, programmed my own access databases and Excel spreadsheet  and been on projects such as LIMS system validation, I figured I’d make notes on the FDA’s 2016 guidance for industry document regarding Data Integrity and Compliance With CGMP.  This draft is for currently open for comment and the guidance addresses data integrity in:

Notes on ISO 13408-2 (2003) – Aseptic processing of health care products – Part 2 : Filtration

I found the latest ISO online here.  As far as I can tell it is legit (in so far as allowing the ISO online for free) – it certainly is the current ISO.

A recent HR rep from a pharmaceutical company contacted me regarding an open role I Sydney.  After passing my details along to “senior management”, the response I got was “We have had some discussion with senior quality managers about your profile and unfortunately they feel your relevant experience in Sterile Micro going back 10 years is a little too long for us ideally”.

Such a response show a lack of foresight from the employer as they do not want the best candidate for the job.  Do they want someone who knows their stuff?  No.  Do they have a commitment to training and staff development?  No. Continue reading

Notes on International Standard ISO 13408-1: 2008

One of the main International Standards used as a reference document in a sterile pharmaceutical microbiology laboratory is ISO13408 – Aseptic Processing of Health Care Products .  Long ago, I reviewed the 1998 edition.  More recently, I acquired ISO 13208-1 (2008), so I compared my notes from the 1988 version with what is stated in the 2008 version.  The use of italics is my way of emphasising points.  Notes on changes are in blue.

INTRODUCTION

When I reviewed the 1998 edition, I did not note down any of the introduction.

  • Anything labelled as sterile needs to made under tight control as part of a Quality Management System
  • This part of the ISO focusses on the risks to the maintenance of sterility
  • All possible sources of contamination need to be controlled and a risk based approach is recommended
  • Appropriate validation of the aseptic process is needed and process simulation trials are an essential part of this

A great reference for ensuring you are audit ready are the FDA’s Guide to Inspections documents and Guidance for Industry documents.

The FDA Inspection guides are freely available from here.

For my own reference and review, I’ve saved some of the Guidance for Industry documents below.  However, you can get them all from this link.

Notes on International Standard ISO 13408-1: 1998(E)

One of the main International Standards used as a reference document in a sterile pharmaceutical microbiology laboratory is ISO13408 – Aseptic Processing of Health Care Products .  Long ago, I reviewed the 1998 edition.  The 2008 edition of the standard was last reviewed and confirmed in 2011 as current.  Part 1 details the general requirements.  The 2008 edition is edition 2 and is a techncial revision of the 1998 document.  The guts of the standard are not dissimilar to version 1.

My review of the 1998 edition follows.  When I get my hands on the 2008 edition, I’ll review that with reference to this review.

The use of italics is my way of emphasising points. Continue reading
