Shared Supplier Audits
By Helena Champion, Drug Quality Assurance | September 6, 2012
A new day for supply chain quality
Drug and device companies I work with are often resource- and time-constrained and, while we audit drug substance and drug product contract manufacturing organizations, we may give less attention to other materials such as excipients and chromatography resins, especially during early clinical development. However there are safety risks with some commodity excipients and materials, such as glycerin and gelatin capsules, to name some recent adulterated materials in the headlines and we don’t know what material may be adulterated next! It makes sense to use shared resources that are available from independent organizations to help qualify material suppliers and to monitor supply chain issues.
Most adulterated products come from supply chains unknown to the drug or device manufacturer. The European Directive 2011/62/EU (prevention of falsified medicinal products) requires drug manufacturers to verify compliance by manufacturers and distributors of active substances with GMP and GDP by means of onsite audits. The FDA has indicated that we should know the full supply chain for materials at risk and they are now reviewing supplier qualification more carefully during inspections.
Supplier qualification of any one material is multifaceted and difficult for a number of reasons:- Qualification of a supplier is specific to a single manufacturing location and for specific materials and manufacturing operations performed at that location.
- The actual site of manufacture of a chemical or component may be different from the site where it is packaged in small quantities for the customer
- Often a number of distributors and brokers are involved with the supply of a chemical or component
- Some suppliers to the pharmaceutical industry get their materials from brokers who may change material sources at any time to reduce costs. The FDA does not require brokers of excipients to register, and very few of them have ever been inspected. How can the supply chain be verified?
- It is usually not clear on the certificate of analysis where testing was performed.
It requires considerable quality expertise and resources to establish an effective supplier qualification program, to perform supplier audits and to discover and verify the full supply chain for materials.
How can we do our best to avoid adulterated and low quality materials? Risk assessment is useful to prioritize and decide which materials suppliers require more attention. We know we need to purchase materials from suppliers that deal with high-quality manufacturers, distributors and brokers who know and monitor the entire supply chain, to avoid risk of adulteration, but that is easier said than done. How do we find out the supply chain and whether our supplier really monitors the supply chain, other than by audit after extensive confidentiality negotiations?
It makes sense to share this effort with other companies using the same materials by using whatever shared independent industry resources are available, to ensure we are using well qualified suppliers for our materials.
Audit Sharing
Audit sharing is a resource that I have used and recommend. Third party audits are accepted by the EMA and FDA as long as they are relevant. “Relevant” means the audit and report must relate to a particular supplier facility and to materials made at that facility that are used by the drug or device manufacturer and the report needs to be recent. The IPEA audit report I bought on behalf of a client two years ago covered the essential topics, was well written and told the unvarnished truth, in that it noted that the manufacturer of the relevant excipients did not audit its suppliers. (Not good news.) I expect that other organizations that offer shared audits, such as Rx-360 and others, will also offer reliable audit reports.
The International Pharmaceutical Excipients Council (IPEC)has offered a number of shared audit reports over the past few years. IPEC-Americas has more than 70 members, mostly excipient and raw materials producers and finished drug product manufacturers. IPEA (International Pharmaceutical Excipients Auditing, Inc., a subsidiary of IPEC-Americas) has launched a program to provide IPEA Certification of Conformance with Excipient GMPs and six excipient GMP Conformance Certification Audit Reports are available for $750 each. Seven other recent Audit reports are available for $1,500 each. Some of these reports cover multiple excipients made at a particular facility. The IPEA audits evaluate compliance with the NSF 363/ ANSI American National Standard for Excipient GMP.
Rx-360 is an organization focused on pharmaceutical supply chain security that currently offers shared audit reports (19 at last count), each covering a particular supplier facility and named materials: raw materials, excipients, chromatography resins, APIs. They charge non-members $5,000 for a report and members pay $2,500. They report having a backlog of 378 audit requests, which should result in a large number of useful audit reports. Rx-360 was founded in 2009 by volunteers from the pharmaceutical and biotech industry and their suppliers, with members including 25 drug product manufacturers, 31 suppliers and various associations and auditors. Their web site (www.rx-360.org) is a useful resource for current supply chain issues.
EXCiPACT plans to offer independent third party certification and supply chain assessment of manufacturers, suppliers and distributors of pharmaceutical excipients worldwide. EXCiPACT was founded in 2012 by volunteers from IPEC-Europe, IPEC-Americas, European Fine Chemicals Group (EFCG) and others to provide independent third party certification of manufacturers, suppliers and distributors of pharmaceutical excipients. Certification will be to an ISO 9001 GMP Annex, similar to IPEA excipient GMP certification. IPEC-Europe has around 76 members, mostly excipient and drug manufacturers.
APIC is a European group that offers third party API audit reports. The name refers to the Active Pharmaceutical Ingredients Committee, Sector Group within CEFIC/European Chemical Industry Council. APIC has performed three third party GMP Audits in Germany recently and is likely to do many more in the near future, considering the European Directive to prevent falsified medicines requires onsite audits of API manufacturers and distributors.
