In pharmaceutical contract manufacturing, the work of analytical scientists is covered by a quality agreement, which is prepared by personnel in the quality control or quality assurance department and focuses on the laboratory analyses provided. But what exactly are quality agreements, why do we need them, who should be involved in writing them, and what should they contain? Here, we answer those questions.
What are quality agreements, why do we need them, who should be involved with writing them, and what should they contain?
In May, the Food and Drug Administration (FDA) published new draft guidance for industry entitled "Contract Manufacturing Arrangements for Drugs: Quality Agreements" (1). I just love the way the title rolls off the tongue, don't you? You may wonder what this has to do with spectroscopy or indeed an analytical laboratory, which is a fair question. The answer comes on page one of the document where it defines the term "manufacturing" to include processing, packing, holding, labeling, testing, and operations of the "Quality Unit." Ah, has the light bulb been turned on yet? Testing and operations of the quality unit — could these terms mean that a laboratory is involved? Yes, indeed.
Paddling across to the other side of the Atlantic Ocean, the European Union (EU) issued a new version of Chapter 7 of the good manufacturing practices (GMP) regulations that became effective on January 31, 2013 (2). The document was updated because of the need for revised guidance on the outsourcing of GMP regulated activities in light of the International Conference on Harmonization (ICH) Q10 on pharmaceutical quality systems (3). The chapter title has been changed from "Contract Manufacture and Analysis" to "Outsourced Activities" to give a wider scope to the regulation, especially given the globalization of the pharmaceutical industry these days. You may also remember from an earlier "Focus on Quality" column (4) dealing with EU GMP Annex 11 on computerized systems (5) that agreements were needed with suppliers, consultants, and contractors for services. These agreements needed the scope of the service to be clearly stated and that the responsibilities of all parties be defined. At the end of clause 3.1 it was also stated that IT departments are analogous (5) — oh dear!
Also, ICH Q7, which is the application of GMP to active pharmaceutical ingredients (APIs), has section 16 entitled "Contract Manufacturing (Including Laboratories)." This document was issued as "Guidance for Industry" by the FDA (6) and is Part 2 of EU GMP (7). Section 16 states that "There should be a written and approved contract or formal agreement between a company and its contractors that defines in detail the GMP responsibilities, including the quality measures, of each party." As noted in the title of the chapter, the scope includes any contract laboratories, which means that there needs to be a contract or formal agreement for services performed for the API manufacturer or any third-party laboratory performing analyses on their behalf.
Therefore, what we discuss in this gripping installment of "Focus on Quality" is quality agreements, why they are important for laboratories, and what they should contain for contract analysis. The principles covered here should also be applicable to laboratories accredited to International Organization for Standardization (ISO) 17025 and also to third-party providers of services to regulated and quality laboratories.
According to the FDA, a quality agreement is a comprehensive written agreement that defines and establishes the obligations and responsibilities of the quality units of each of the parties involved in the contract manufacturing of drugs subject to GMP (1). The FDA makes the point that a quality agreement is not a business agreement covering the commercial terms and conditions of a contract, but is prepared by quality personnel and focuses only on the quality of the laboratory service being provided.
Note that a quality agreement does not absolve the contractor (typically a pharmaceutical company) from the responsibility and accountability of the work carried out. A contract laboratory should be viewed as an extension of the company's own facilities.
Put at its simplest, the purpose of a quality agreement is to manage the expectations of the two parties involved from the perspective of the quality of the work and the compliance with applicable regulations. Under the FDA there is no explicit regulation in 21 CFR 211 (8), but it is a regulatory expectation as discussed in the guidance (1).
In contrast, in Europe the requirement is not guidance but the law that defines what parties have to do when outsourcing activities as (2):
Any activity covered by the GMP Guide that is outsourced should be appropriately defined, agreed and controlled in order to avoid misunderstandings which could result in a product or operation of unsatisfactory quality. There must be a written Contract between the Contract Giver and the Contract Acceptor which clearly establishes the duties of each party. The Quality Management System of the Contract Giver must clearly state the way that the Qualified Person certifying each batch of product for release exercises his full responsibility.
Typically, there will just be two parties to a quality agreement; these are defined as the contract giver (that is, the pharmaceutical company or sponsor) and the contract acceptor (contract laboratory) according to EU GMP (2). Alternatively, the FDA refers to "The Owner" and the "Contracted Facility" (1). Regardless of the names used, there are typically two parties involved in making a quality agreement unless, of course, you happen to be the Marx Brothers (the party of the first part, the party of the second part … the party of the 10th part, and so forth) (9).
If the contact acceptor is going to subcontract part of their work to a third party, then this must be included in the agreement — with the option of veto by the sponsor and the right of audit by the owner or the contracted facility.
Figure 1 shows condensed requirements of EU GMP Chapter 7 regarding the contract giver or owner and the contract acceptor or contracted facility to carry out the work. Responsibilities of the owner are outlined on the left-hand side of the figure and those of the contracted facility are outlined on the right-hand side of the diagram. The content of the contract or quality agreement is presented in the lower portion of the figure. These points will be discussed as we go through the remainder of this column.
Figure 1: Summary of EU GMP Chapter 7 requirements for outsourced activities.
According to the FDA (1), a quality agreement has the following sections as a minimum:
Although quality agreements can cover the whole range of pharmaceutical development and manufacturing, for the purposes of this column we will focus on the laboratory. In this discussion, the term laboratory will apply to a laboratory undertaking regulated analysis either during the research and development (R&D) or manufacturing phases of a drug product's life, including instances where the whole manufacturing and testing is outsourced to a contract manufacturing organization (CMO), the whole analysis is outsourced to a contract research organization (CRO) or testing laboratory, or just specialized assays are outsourced by a company. In fact, there are specific laboratory requirements that are discussed in the FDA guidance (1).
The scope of a quality agreement can cover one or more of the following compliance activities:
All activities under the scope of the quality agreement must be conducted to the applicable GMP regulations.
Now, I want to go into more detail about some selected sections of a quality agreement. I would like to emphasize that this is my selection and for a full picture readers should refer to the source guidance (1) or regulation (2).
Procedures and Specifications
In the majority of instances the owner or contract giver will supply their own analytical procedures and specifications for the contract laboratory to use. These will be specified in the quality agreement. Part of the quality agreement should also define who has the responsibility for updating any documents. If the owner updates any document within the scope of the agreement, then they have a duty to pass on the latest version and even offer training to the contract facility. To ensure consistency, the owner could require the contract laboratory to follow the owner's procedure for out-of-specification results.
The responsibilities of the two groups signing the agreement will depend on the amount of work devolved to the contract laboratory and the degree of autonomy that will be allowed. For example, if a laboratory is used for carrying out one or two specialized tests rather than complete release testing, then the majority of the work will remain with the owner's quality unit. The latter will handle the release process and the majority of work. In contrast, when the whole package of work is devolved to a CMO, then the responsibilities will be greatly enlarged for the contract laboratory and communication of results, especially exceptions, will be of greater importance.
In any case, the communication process between the laboratory and the owner needs to be defined for routine, escalation, and emergency cases. How should the communication be achieved? The choices could be phone, fax, scanned documents, e-mail, on-line access to laboratory systems, or all of the above. However, it is no good having the communication processes defined as they will be operated by people, therefore analysts, quality assurance (QA) staff, and their deputies involved on both sides have to be nominated and understand their roles and responsibilities.
Communication also needs to define what happens in case of disputes that can be raised from either party. The agreement should document the mechanism for resolving disputes and, in the last resort, which country's legal system will be the beneficiary of the financial largesse of both organizations as they fight it out in the courts. Unsurprisingly, I'm in the camp with the great spectroscopist "Dick the Butcher" who said "The first thing we do, let's kill all the lawyers" (11).
Records of Complete Data
Just in case you missed it above, the contract laboratory must generate complete data as required by GMP for all work it undertakes. This will include both paper and electronic records that I discussed in an earlier "Focus on Quality" column (10). The FDA guidance makes it clear that the quality agreement must document how the requirement for "immediate retrieval" will be met by either the owner or the contract laboratory (1). Both types of records must be protected and managed over the record retention period.
The agreement needs to specify which controlled and documented changes can be made by the contract laboratories with only the notification to the owner and those that need to be discussed, reviewed, and approved by the owner before they can be implemented. Of course, some changes, especially to validated methods or computerized systems, may require some or complete revalidation to occur, which in turn will create documentation of the activities.
To reduce the possbility of any misunderstanding, a glossary that defines key words and abbreviations is an essential component of a quality agreement.
In the quality agreement guidance (1), the FDA makes the point that contract laboratories are subject to GMP regulations and discusses two specific scenarios. These are presented in overview here, please see the guidance for the full discussion.
Scenario 1: Responsibility for Data Integrity in Laboratory Records and Test Results
Here, the owner needs to audit the contract laboratory on a regular basis to assure themselves that the work carried out on their behalf is accurate, complete data are generated, and that the integrity of the records is maintained over the record retention period. This helps ensure that there will be no nasty surprises for the owner when the FDA drops in for a cozy fireside chat.
Scenario 2: Responsibilities for Method Validation Under Actual Conditions of Use
Here, a contract laboratory produces results that are often out of specification (OOS) and has inadequate laboratory investigations. The root cause of the problem is that the method has not been validated under actual conditions of use as required by 21 CFR 194(a)(2): The suitability of all testing methods used shall be verified under actual conditions of use (8).
As that great analytical chemist Ronald Reagan said, "trust but verify" (this is the English translation of a Russian proverb). Auditing is used before a quality agreement and confirms that the laboratory can undertake the work with a suitable quality system. Afterwards, when the analysis is on-going, auditing confirms that the work is being carried out to the required standards. Both the FDA and the EU require the owner or contract giver to audit facilities they entrust work to.
There are three types of audit that can be used:
Audits are a key mechanism to provide the confidence that the contact laboratory is performing to the requirements of the quality agreement or contract. If noncompliances are found, they can be resolved before any regulatory inspection.
There will be a number of people within the quality function of both organizations involved in the negotiation and operation of a quality agreement. Typically, some of the roles involved could be
One of the ways that each role is carried out is to define them in the agreement, which can be wordy. An alternative is to use a RACI (pronounced "racy") matrix, which stands for responsible, accountable, consulted, and informed. This approach defines the activities involved in the agreement and for each role assigns the appropriate activity. For example, the release of the batch would be the responsibility of the sponsor's quality unit in the United States or the qualified person in Europe.
A simple RACI matrix for the transfer of an analytical procedure between laboratories is shown in Table I. The table is constructed with the tasks involved in the activity down the left hand column and the individuals involved from the two organizations in the remaining five columns. The RACI responsibilities are shared among the various people involved.

For those that are interested in gaining further information about quality agreements there are a number of resources available:
The FDA acknowledges in the conclusions to the draft guidance (1) that written quality agreements are not explicitly required under GMP regulations. However, this does not relieve either party of their responsibilities under GMP, but a quality agreement can help both parties in the overall process of contract analysis — defining, establishing, and documenting the roles and responsibilities of all parties involved in the process. In contrast, under EU GMP quality agreements are a legal and regulatory requirement.
