An Analysis Of MHRA's Annual GMP Inspection Deficiencies Report

By Barbara Unger, Unger Consulting Inc.

The U.K.’s Medicines and Healthcare products Regulatory Agency (MHRA) has taken a different approach in the publication of the GMP deficiencies for drug product issued during inspections in 2018 and published in October 2019. In 2015 and 2016, the MHRA provided approximately 100 slide decks with tables, figures, and text from deficiencies against the requirements in the chapters and annexes. No data were published for 2017. The MHRA published a 6,200+ line Excel spreadsheet of its 2018 GMP inspection data so that individuals can parse and present the data according to their needs.

This two-part article is data dense and includes many tables and figures. Part 1 begins with a high-level overview of the 2018 data, including additional trends from the two most recent MHRA reports, from 2015 and 2016. It then goes on to identify and evaluate the critical and major deficiencies from 2018, identifying the chapters and annexes associated with critical and major deficiencies. For critical deficiencies citing Chapter 1 and Annex 1, the specific paragraphs and requirements with which they are associated are identified.

Part 2 presents the 10 most frequently cited paragraphs for the 10 chapters and annexes with the most frequently cited deficiencies identified in Part 1.

Background

I found the “Notes and Guidance” segment of the MHRA spreadsheet a bit confusing. In light of this, here’s how I’ve parsed the data. Each row in the spreadsheet is treated as a unique deficiency, regardless of whether it is a “deficiency” or a “sub-point” as identified in the Notes and Guidance section of the MHRA publication. I cannot discern which is which in the spreadsheet, so I treat them all equally. The summary data from 2015 and 2016 are taken directly from the MHRA 2016 report. Data were not posted for 2017. Any mistakes in this analysis and reporting of the 2018 data are mine, not the MHRA’s.

Overall Data

The MHRA conducted 285 GMP inspections, both domestic and outside of the U.K., in 2018. Inspections outside the U.K. were conducted in Bangladesh, China, India, Japan, Singapore, South Korea, and the United States. Country-specific data, other than that provided for the U.K. and “overseas,” was not provided in the 2015 and 2016 MHRA reports. The 285 inspections from 2018 reflect a decrease from the number of inspections conducted in both 2015 and 2016.

Table 1 identifies the number of drug product inspections, by country, performed by the MHRA in 2018. As in past years, almost all MHRa inspections were conducted in the U.K. The percentage of inspections conducted in the U.K. in 2018 increased slightly from 2015 and 2016 and the percentage of overseas inspection decreased slightly in 2018 to 20 percent of the total.

In 2018, the largest number of inspections conducted outside the U.K. were performed in India, with a total of 43. The remaining 14 inspections outside the U.K. were conducted in six countries, with China and the U.S. each the subject of five inspections, and the other countries with one each.

Table 2 shows the trend, including all classification of deficiencies from 2015, 2016, and 2018 identified in the top 10 chapters and annexes. Data from 2015 and 2016 are taken directly from the 2016 report published by the MHRA. Quality Systems leads the list in all three years. Notable changes in 2018 from the two previous years include:

  • Outsourced Activities (Chapter 7) appears within the top 10 in 2018, though it did not appear in either of the two other years.
  • Personnel (Chapter 2) is no longer among the top 10 in 2018.
  • Computerised Systems (Annex 11) remains within the top 10 in 2018, although it fell from fifth place in 2015, to seventh in 2016, and to 10th place in 2018.
  • Complaints and Recalls (Chapter 8) also diminished in rank over the time period, from second in 2015, to fourth in 2016, and eighth in 2018.

Figure 1 and Figure 2 present the total number of deficiencies according to the GMP chapter or GMP annex cited, respectively. These figures include all deficiency classifications — critical, major, and other. Annex 15, Qualification and Validation, and Annex 1, Sterility Assurance, take first and second place among the most frequently cited annexes, with approximately 600 and 450 deficiencies, respectively. This is followed by Annex 11, Computerized Systems, and Annex 16, Certification by a Qualified Person and Batch Release. All other annexes are associated with double-digit or fewer deficiencies.

Chapter 1, Quality Management, with approximately 1,500 citations, has more than twice the number of deficiency citations as the nearest chapter. Chapter 4, Documentation, with almost 760 deficiencies, is closely followed by Chapter 5, Production, with just over 650, and Chapter 3, Premises and Equipment, at just under 570 citations. Chapters 2, 6, 7, and 8 each had between 200 and 400 deficiencies and, of the two remaining two chapters, one had fewer than 50 citations and the other had just one citation.

Figure 3 shows the top 10 categories when values from annexes and chapters are combined; the same information is provided in Table 2 with the number of associated deficiencies. Again, this includes all categories of deficiencies. The top 10 citations in each of these categories will be identified in Part 2.

Critical And Major Deficiencies

Table 3 provides a tabulation of all 2018 deficiencies by their classification. Critical deficiencies clearly constitute the smallest category; additional detail on these will be provided later. Major deficiencies constitute almost 40 percent of the total, and other deficiencies constitute the majority of the deficiencies at almost 60 percent of the total.

The majority of critical and major deficiencies among the 6,200-plus deficiencies cluster in a few chapters and annexes. Figure 4 shows the number of critical deficiencies and the chapters or annexes that are referenced. Among the critical deficiencies, 37 percent are associated with Chapter 1, Quality Systems, and 22 percent are associated with Annex 1, Sterility Assurance. Annexes 1 and 11 are the only other annexes that include citations for critical deficiencies; the remainder cite GMP chapters.

Tables 4 and 5 provide the specifics on the citations for Chapter 1 and Annex 1, respectively. The tables include the identifying paragraph, the number of times the deficiency was cited, and a short version of the text in the GMP guide.

Figure 5 shows 12 annexes and chapters associated with major deficiencies and the number of times they were cited. In addition to these 12 chapters and annexes, major deficiencies were identified in Chapter 9 (11), Annex 2 (4), Annex 8 (8), Annex 3 (3), Annex 13 (3), and one each in Annex 6 and Annex 19. More GMP chapters and annexes were cited in major deficiencies than were cited in critical deficiencies. Among the major deficiencies, 33 percent are associated with Chapter 1, 11 percent are associated with Annex 15, 11 percent are associated with Annex 1, and 10 percent are associated with Chapter 5. Shortcomings in Quality Systems clearly lead the list of both critical and major deficiencies, demonstrating the agency’s focus on the importance of a sound quality system to GMP compliance.

Conclusions

  • In 2018 the MHRA conducted fewer inspections than in 2015 and 2016. The percentage of inspections conducted in the U.K. increased slightly and those outside the U.K. decreased slightly over that period. It will be useful to monitor whether the MRA with the FDA results in a decrease in the number of inspections of sites that they may both inspect. Because the MHRA only conducted five inspections in the U.S., it will be difficult to determine if the MRA with the FDA results in a decrease of inspection in the U.S.
  • Chapter 7, Outsourced Activities, was new among the top 10 in 2018 but was not in the top 10 in either 2015 or 2016, and Chapter 2, Personnel, was no longer in the top 10 in 2018.
  • In no surprise that Quality Systems, Chapter 1, continues to be first among the areas cited in inspection deficiencies, regardless of classification, with more than double the number of deficiencies of the next area, Chapter 4. Chapter 1 is first among all deficiencies regardless of classification, first in number among the critical deficiencies, and first in number among the major deficiencies.
  • Critical deficiencies constitute only 2 percent of the total identified in 2018 and these are associated primarily with Chapter 1 and Annex 1. Approximately 37 percent of critical deficiencies cite requirements in Chapter 1 and approximately 22 percent cite requirements in Annex 1.
  • Among the major deficiencies that constitute approximately 40 percent of the total deficiencies, Chapter 1 again leads the group with almost 800 deficiencies. The next three include Annex 15 with approximately 270, Annex 1 with approximately 260, and Chapter 5 with approximately 250. Clearly, Quality Systems is again the substantial leader, as it is for critical deficiencies. Chapter 7, Chapter 8, and Annex 16 were among the top 10 in major deficiencies yet not among the top 10 for critical deficiencies.
  • Computerised Systems, Annex 11, remains in the top 10, reinforcing the importance of this area to data integrity and the regulator’s focus on the control and management of electronic data.

Hopefully, the MHRA will publish similar data in 2019 to which we can compare these data. It would be useful for the MHRA to publish the actual text of deficiencies from the various areas in future years as it did in the past. But in the absence of that, publication of these data is valuable and appreciated by the industry.
