Q&A: Good clinical practice (GCP)
(GMP guidelines, §4.18: Before any packaging operation begins, there should be recorded checks that the equipment and work station are clear of previous products, documents or materials not required for the planned packaging operations, and that equipment is clean and suitable for use).
The packaging should be performed in such a way as to limit the risk of possible mix-up between the test and reference product. To this effect:
- the test and the reference product should be packaged during separate operations and should not be available simultaneously in the packaging area;
- during these operations not only should the test and reference products be kept separate, but also all material used for the packaging of each product (containers, labels) and the batch record documents. Material used for different products should not be available in the packaging area simultaneously;
- reconciliation should be performed for the quantities of IMP units, containers and labels introduced in the working area, used during the packaging and remaining after these operations, before the area is cleared and before the packaged IMPs are released;
- the working area should be cleared of all IMP, packaging material and documents between the packaging operations of the test and of the reference product (line clearance). If packaging is performed for several trials successively line clearance should be ensured between each product and each trial;
- once the packaging has been completed for all products to be packaged for a given trial and the products have been released, the packaged test and reference products can be taken simultaneously into the packaging area for further operations (e.g. sorting the containers per subject number);
- critical steps should be controlled in-process by appropriately qualified and trained staff.
In the case of liquid formulations the volume packaged should be measured with appropriate precision and accuracy. If a reconstitution of the product is needed the instructions provided with the product should be followed. If a specified volume of fluid is to be used for the reconstitution this volume should be measured with appropriate precision and accuracy.
At least the following elements should be checked in-process by the operator and independently by a second person:
- line clearance before and after packaging;
- information on the labels, labelling of the containers, compliance with the randomisation code;
- identity of the product introduced in the working area (name, batch number, formulation), consistency with the identity mentioned on the labels, compliance with the protocol, consistency between the physical appearance of the product and the description of the product in the batch release certificate provided by the sponsor;
- for each container, number of IMP units introduced into the container, compliance with the protocol requirements;
- in the case of a liquid formulation: adequate reconstitution of the product if needed, volume dispensed/packaged into each container;
- reconciliation of IMP units, containers, labels.
A standard operating procedure (SOP) should describe the packaging operations step by step, including the controls to be performed at each step and the responsibilities of each person involved.
These operations should only be performed by authorised personnel, qualified by training and education.
Access to IMPs should be limited to authorised personnel, both before and after packaging. Storage conditions should conform to the provisions of the protocol (temperature, humidity, protection from light if and as appropriate).
All operations performed, including the controls, should be documented in detail step by step at the time each action is taken. The persons performing each task should be clearly identified (operators and controllers). All precautions taken to avoid mix-ups should be documented in the batch records. Batch records should include at least the following information:
- line clearance before the start of the packaging operations, and between the packaging of different products;
- date and time the packaging operation is started and completed, for each product;
- identity of the product packaged, including the batch number, expiry date and a physical description of the product;
- type of container used for packaging, including the closing/stopping material;
- numbers of the subjects for whom the product is prepared, or precise reference to the randomisation list followed (reference number, seed used to generate the list). In such a case a copy of the randomisation list, which should be dated and signed when edited, should be attached to the batch record;
- number of IMP units dispensed per container;
- if the IMP was provided to the CRO packaged under blister strip, whether the IMP was removed from the blister or whether the blister was cut and the IMP dispensed while still in a piece of blister strip;
- in the case of a liquid formulation, how the product was reconstituted if applicable, material used to measure the volume dispensed/packaged into each container; and expiry date of the finished product if applicable.
- number of IMP units, containers and labels introduced in the working area, used and remaining (reconciliation);
- mention of any special problem or unusual events, and signed authorisation for any deviation from the instructions;
- release of the packaged products after all checks and controls are completed (authorisation to use the products for the trial after all necessary verifications have been performed and the necessary documentation has been completed).
Copies of the labels, showing they have been checked against the randomisation list and approved, should be appended to the batch records.
All controls performed, and the identity of the person(s) performing each control, should be documented with the signature of the individual in charge.
As the test and reference product are to be packaged separately the use of separate batch records per product is strongly encouraged. If IMP are to be packaged/dispensed during separate operations for each trial period, separate batch records should be kept for each period.
Labelling shall be such as to ensure protection of the subject and traceability, to enable identification of the product and trial, and to facilitate proper use of IMP.
Labelling of the containers should conform with the local regulatory requirements.
The labelling on each container should comprise at least the following information:
- trial reference code;
- trial subject identification number;
- batch and/or code number to identify the contents and packaging operation;
- period number;
- pharmaceutical dosage form, route of administration, quantity of dosage units per container;
- the identity of the product;
- period of use (use-by date, expiry date or retest date as applicable), in month/year format and in a manner that avoids any ambiguity;
- storage conditions.
The use the words "dispensation" or "dispensing" to refer to the provision of a prepared dose of an identified medication to the subject is not recommended in order to avoid possible misunderstandings and confusion. This operation is more properly defined as administration. Administration includes directly introducing the medication into or onto the individual's body.
The process for IMP administration to the subjects should be described in an SOP.
The documentation generated at the time of IMP administration to the subjects should indicate unequivocally the identity of the product administered to each subject, except in the case of a blinded trial. Several possibilities exist to document this administration adequately:
- use of a tear-off label, to be stuck on the case report form (CRF) at the time of IMP administration. This ensures confidence that each subject indeed received the IMP that was packaged for him. An appropriate documentation of the packaging operations is of the utmost importance;
- documentation of the identity of the IMP directly in the CRF at the time of IMP administration. If this information is read directly from the label on the IMP container an appropriate documentation of the packaging operations is of the utmost importance. If there is a physical difference between the test and the reference product (e.g. difference in pharmaceutical formulation, colour, shape, markings) it is recommended to record this physical characteristic in the CRF at the time of administration. The subject might be asked to sign a statement with a description of the IMP he is given, in a language understandable to him. If the documentation on the packaging is insufficient this physical characteristic should be used to check the identity of the product administered against the randomisation list. This check should be documented at the time of administration.
The number of IMP units administered to each subject should be documented at the time of administration.
Compliance with the requirements of the protocol regarding the conditions of administration should be documented: volume of water taken with the IMP, administration in the fed or fasted state, posture etc.
Adherence to the protocol is a fundamental part of the conduct of a clinical study. Any significant change to the protocol should be submitted as an amendment to the competent regulatory authority and ethics committee. Significant changes to the protocol include any change in inclusion and exclusion criteria, addition or deletion of tests, dosing, duration of treatment etc (see the definition of a substantial amendment in the 'detailed guidance for the request for authorisation of a clinical trial on a medicinal product for human use to the competent authorities, notification of substantial amendments and declaration of the end of the trial' published by the European Commission in chapter I, volume 10 of the rules governing medicinal products in the European Community). Deviations from the inclusion/exclusion criteria of the protocol might erode the scientific and ethical value of the protocol and its authorisation and might have an impact on the processes put in place for the care and safety of the study subjects.
Sponsors and investigators should not use systems of prospectively approving protocol deviations, in order to effectively widen the scope of a protocol. Protocol design should be appropriate to the populations required and if the protocol design is defective, the protocol should be amended.
GCP does permit deviations from the protocol when necessary to eliminate immediate hazards to the subjects but this should not normally arise in the context of inclusion/exclusion criteria, since the subject is not yet fully included in the trial at that point in the process GCP inspectors have observed a number of sponsors implementing systems where the investigator can contact the sponsor, usually the Medical Monitor, and request a prospective approval to deviate from the inclusion and/or exclusion criteria. The use of such systematic waiver systems in clinical trials is not considered to be appropriate and studies using such a system might be regarded as non-compliant with GCP.
Niche subcontractors are used increasingly for carrying out specific tasks of the sponsor, such as monitoring, data management, Interactive voice response systems (IVRS), management of electronic patient diaries or CRFs etc. In addition there are contractors who undertake tasks that are partly or wholly related to the responsibilities of the investigator, even though the contractor may have their main contract with, and be paid by, the sponsor (such tasks may include specialised testing, source data retention (especially in the context of e-CRF or e-patient diary) or patient recruitment or follow-up contacts).
This fragmented distribution of tasks could put additional strain on the maintenance of quality assurance and compliance and obscure the clear responsibility and reporting lines for these tasks.
Great care is therefore needed in ensuring that the distribution of tasks is clearly documented and agreed, that each party has the control and access to data and information that their legal responsibilities require and that the ethics committees and regulatory authorities approving trials have been properly informed of these activities as part of the clinical trial application process.
The legal framework:
The responsibility for the conduct of clinical trials is assigned, by Directive 2001/20/EC1, and by the note for guidance on GCP (CPMP/ICH/135/952), to two entities – the sponsor and the investigator.
The roles of the sponsor, investigator, contract research organisation (CRO) and, monitor, are further defined and described in Directive 2005/28/EC3 and in the glossary and chapters 4 and 5 of the note for guidance on GCP (CPMP/ICH/135/95).
A number of the tasks involve access to, review, collection and/or analysis of data, much of it personal data, and in specific cases contact with study subjects or potential study subjects. Data protection legislation needs to be followed, in addition to the clinical trial legislation and guidance. Directive 95/46/EC4 sets out requirements for the protection of individuals with regard to the processing of personal data and on the free movement of such data. The specific requirements foreseen by local legislation, setting out the provisions for personal data protection, ethical review and informed consent, should be followed.
Contracts and agreements
All the clinical trial related tasks are ultimately the responsibility of either the sponsor or the investigator. Great care should be taken that the relative distribution of tasks to the different parties is well defined, making clear the ultimate responsibilities in the context of each clinical trial. This should be carefully documented, in the protocol, procedures, contracts or agreements and other documents.
The specifics of each particular clinical trial need to be taken into account when planning the trials, during their conduct and monitoring and by audits or inspections.
This is particularly important where entering into novel arrangements that may arise, for instance in the case of site management organisations (SMOs) or other organisations conducting tasks that relate to the responsibilities of the investigator but where the organisation has its contract and funding with the sponsor. These tasks can often involve contact with the study subjects.
The sponsor/CRO should determine the extent of monitoring of each party, within the context of GCP, under particular circumstances. This should be justifiable, and ensure GCP compliance, in the context of the clinical site organisation and the nature of the product and protocol being studied.
Contact with patients
Where direct contact with study subjects or their carers/guardians is involved, the privacy and confidentiality of those involved and of any information maintained or collected needs to be respected in compliance with the GCP and clinical trial requirements and with the personal data protection legislation. Such contacts need to be considered in advance by the ethics committees concerned and be given a positive opinion, either as part of the study specific opinion from the ethics committee or a more general opinion in the context of subject screening procedures, which are not study specific.
Personal details such as identity or contact information should not be communicated outside of the parties who have received the ethics committee approval and should not be used or communicated for purposes other than those agreed by the ethics committee and consented to by the study subjects, and where applicable, their carers or others who may be contacted and whose details might be retained.

Source data is defined in International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) GCP (1.51) as all information in original records and certified copies of original records of clinical findings, observations, or other activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Source data should be accurate, legible, contemporaneous, original, attributable, complete and consistent.
Source data is documented in source documents which may be both electronic and on paper. The following list gives examples of source documents where source data may be located:
- medical records
- laboratory reports
- subject diaries
- nurses' notes
- dispensing logs
- electrocardiogram (ECG) print-outs
- case report forms (CRF)
- X-ray images
- radiological reports, etc.
Purpose of identifying source data location
Verification of source data is a considerable part of the work of monitors, auditors and inspectors.
During GCP inspections, it is frequently seen that data are recorded in multiple locations at a site.
It is therefore essential to the possibility of reconstructing the clinical trial that it is clear, where the original record is documented. The identification list of where source data is documented is primarily intended as a tool for monitors, auditors and inspectors in their work of verifying that the trial is performed in keeping with the ICH GCP guidelines, current legislation and guidelines as well as the trial protocol.
Requirements for source data
According to ICH GCP (6.4.9), the protocol should identify any data to be recorded directly into the CRFs that are considered to be source data.
According to the recently published reflection paper on expectations for electronic source data and data transcribed to electronic data collection tools in clinical trials, a detailed diagram and description of the transmission of electronic data should be provided in the protocol. The source data and their respective capture methods should be clearly defined prior to subject recruitment (i.e. in the protocol or in a trial specific source data agreement). The sponsor should describe which data will be transferred, the origin and destination of the data, the parties with access to the transferred data, the timing of the transfer and any actions that may be triggered by real-time review of those data.
It is the expectation of the GCP Inspectors' Working Group that investigators are aware about the location of the source data and consistent in recording them. The intended location should be clearly defined prior to subject recruitment. One way of achieving this is to generate a source data location list. This list should be prepared by the site and should be signed and dated by the principal investigator or by a person whom the principal investigator has assigned this task. The list should be filed in the investigator's trial master file.
As the location of source data could vary from one investigator site to another, it could be appropriate to make the list site specific.
The list of source data must be sufficiently detailed
In order to facilitate location of data, the list of source data should be sufficiently detailed. It is often not enough to write 'medical record', as the medical record is often a collective name covering different document types and locations. This may make it necessary to write: 'patient record – dispensing and administration chart', 'medical record – continuation', 'medical record – nurses notes', etc.
It is frequently seen during GCP inspections that the CRF is designed to only include an overall statement regarding a subject's eligibility in the trial. The text in the CRF could for instance say: 'Did the subject satisfy all study entry criteria?'. The statement is typically intended to be answered with 'yes' or 'no'.
The expectation of the GCP Inspectors' Working Group is that adherence to all individual inclusion and exclusion criteria are documented in the source data. Adherence to the criteria of the protocol can originate from different sources like blood samples, physical examination, medical history, information from the subject etc. When designing the protocol and the related CRF, the sponsor should carefully consider where each source data originate from, with reference to a specific visit. This is important since some data originate from screening visits, others from the randomisation visit and some data could be historical.
It should be agreed with the investigator of a site how adherence to the individual criteria is documented.
It is the expectation that a qualified physician who is an investigator or a sub-investigator for the trial has assessed each individual eligibility criteria and has taken the final decision to include the subject in the trial (ICH GCP 4.3.1). This decision should be documented prior to the subject receiving the first dose of the IMP.
GCP inspections have revealed a substantial amount of cases where the overall eligibility statement in the CRF confirms subject eligibility but where source data shows that the subject did not fulfil all eligibility criteria. In addition, it has often not been documented that an investigator/sub-investigator has reviewed all criteria prior to inclusion. It therefore seems that a system with an overall statement in the CRF regarding a subject's eligibility in itself does not ensure the safety of the subjects, the quality of the data and sponsor oversight.
In addition, see related Q&A regarding how and where source data should be defined.
The requirement for investigators to keep a copy of the CRF has been in existence for 20 years. (See for example ICH GCP 8.3.14). It is the expectation of the EU GCP IWG that the copy held by the investigator is a contemporaneous and independent copy of the CRF, i.e. that it is not held or has been held by the sponsor. This requirement is valid irrespective of the media used; however, the introduction of electronic CRFs in clinical trials presents an additional challenge in achieving this requirement - especially if data are being submitted directly via a web based application. This issue has been identified by EU GCP inspectors and discussed in the reflection paper EMA/INS/GCP/454280/2010 (see section 6.2 Specific Requirements Topic 3: control).
Recent inspections have revealed a need to clarify this point.
The 12 requirements in the reflection paper originate from the CDISC standard and are therefore quoted directly in the reflection paper. However, although the CDISC requirements specifically relate to source data, the requirements is considered by the EU inspectors to be also applicable to transcribed data - as stated in the reflection paper section 6.2. Therefore, the requirement of a contemporaneous and independent copy of the CRF is valid irrespective of whether the CRF contains source data or only transcribed data. The EU GCP inspectors do not consider the requirement above to be met if data are captured in an electronic system and the data are stored on a central server under the sole control of the sponsor. This is because the investigator does not hold a contemporaneous and independent copy of the data.
The EU GCP inspectors do not have a preference for any specific solution e.g. a third party vendor, printed data prior to transferring to the database or saving a contemporaneous copy at the investigator's local computer hard drive; the essential point is that choosing an electronic solution should not jeopardise the credibility of data and should not result in lower quality as compared to a paper CRF. It is the responsibility of the sponsor and the investigator to institute a process by which a contemporaneous and independent copy of the CRF is available at the investigator site.
Can the sponsor require that the investigator contacts sponsor staff before unblinding?
According to international guidelines, the treating physician (investigator) is responsible for the medical care of the individual trial subject (Declaration of Helsinki 3§ and ICH GCP 4.3). The coding system in blinded trials should include a mechanism that permits rapid unblinding (ICH GCP 5.13.4). If the blinding is prematurely broken, it is the responsibility of the investigator to promptly document and explain any unblinding to the sponsor (ICH GCP 4.7).
The medical care of the trial subjects includes medical decisions such as whether to start or stop treatment or institute alternative treatment if required. In emergency situations the treating physician, often an investigator, may need to break the treatment code immediately, or as quickly as possible if he/she finds it is in the best interest of the trial subject. Consequently, in order to do so, the investigator must have unrestricted and immediate access to break the treatment code.
Some sponsors have recently introduced a code breaking system that requires the investigator to contact a sponsor representative and only after discussion with the representative, the investigator receives information that unblinds the treatment. Some sponsors have even added a requirement that the investigator submits a written form after the phone call before receiving the information that unblinds the treatment.
It is the opinion of the EMA GCP Inspectors Working Group (GCP IWG) and the Clinical Trial Facilitation Group (CTFG) that the responsibility to break the treatment code in emergency situations resides solely with the investigator. Consequently the sponsor can't require or insist on being involved in the decision to unblind, stall or delay in any way the unblinding of trial subject treatment in emergency situations. The groups also strongly recommend that any sponsor who has introduced or is applying such a system should immediately revise it in order to be compliant with international guidelines.
Breaking the treatment code is usually conducted via code envelopes or electronic systems such as telephone or web based systems such as IVRS and IWRS. When using these kinds of systems the investigator must have direct access in order to break the blind without the interference of the sponsor in any way. In support of electronic systems, a backup system enabling unblinding of treatment must be provided. The CTFG and the GCP IWG acknowledge that such backup systems are operated by the sponsor in a manual way and that the investigator or other treating physician can contact the sponsor staff to unblind the treatment. Still, the sponsor is not entitled to stall or reject unblinding.
Code breaking instructions should be specified clearly in the clinical trial protocol.
In connection with centralised applications, the Committee for Medicinal Products for Human Use (CHMP) often requests a good clinical practice (GCP) inspection of one or more sites to be performed. Prior to such GCP inspections, the European Medicines Agency (EMA) sends an announcement letter to the applicant in which – among others – a list of documents to be provided to the inspection team is presented. The data are used by inspectors for review in order to select patients and data to inspect. Among the requested documents are the individual patient data listings for the patients recruited at the sites to be inspected. Based on past experience, this request for data listings poses a significant number of problems and subsequently costs a lot of time for companies and inspectors, quite often resulting in listings of suboptimal quality.
The aim of this Q&A is to standardise and clarify the format of the data listings to be provided.
It is important to emphasise that the following guidance is the expected standard for most inspections; however, for some trials different, specific requests may be warranted. Consequently, no data should be provided until contact has been established with the reporting inspector and the requirements for data listings have been discussed.
In general, the following is expected:
- All data for the selected sites (and if requested for all sites in the trial) should be provided to the inspectors. That includes all case report form (CRF) data and in addition data which are not necessarily part of the CRF such as data provided to the sponsor by vendors (laboratory data, data from central evaluation of electrocardiograms (ECGs), imaging etc.), data from electronic patient-reported outcomes (ePROs) etc.
- Data should be provided as Excel spreadsheet line listings following the proposed formats and naming detailed below.
- All listings must have raw CRF data and any data derived or imputed from it that forms part of the data analysis.
- Both the CRF data set and the data set used for analysis, for instance as Excel exports from statistical analysis system (SAS), should be provided. They should be provided as exported to Excel document. Any process from raw data to analysed data should be explained if not explained in the statistical analysis plan.
- Paper copies should not be provided unless specifically requested by the inspection team.
- There should be a statement from the sponsor to confirm that the data provided is exactly the same as that submitted in the clinical study reports (CSRs) in the application (this will be checked at the inspection).
Specification of formats and names:
- Naming of all files and Excel spreadsheets should be meaningful and self evident. Columns/name of variable in Excel worksheets could be called adverse event (AE), concomitant medications (CM), vital signs (VS) preferably in accordance with clinical data interchange standards consortium (CDISC) terms. Alternatively a 'translation' document should be provided to explain abbreviations.
- Data should be presented formatted, for example category values 1 and 2 as “yes” and “no” etc. If this isn't done then the format assignment to the data code must be provided.
- The data listings in Excel should ideally be consistent with the layout in the Clinical Study Report CSR, such that cross referencing the data is straight forward.
- Data types and field types should be appropriate for the specific data, for instance numerical data should always be numeric type and not character type, formats can be applied to the numeric data (e.g. dates). This is to allow the inspectors to do their own calculations.
- A copy in PDF format of the CSR listings per patient, for just the particular investigator site to be inspected should generally also be provided. The inspection team may also request to have paper copies brought to the investigator site for source data verification (SDV) purposes. The electronic data should not be an image, such that it is not possible to search, for example by date. There should be a statement from the sponsor to confirm that the data provided as copies in PDF format is exactly the same as that submitted in the CSR(s) in the application (this will be checked at the inspection).
- The data provided in PDF format and Excel worksheets should be set up for printing (e.g. print areas defined and suitable page arrangements set).
Report format of the patient data listings
Unless otherwise agreed with the inspection team, the data should be collected in the groups defined below – each to be presented in a different Excel spreadsheet. The columns ”study site ID”, ”subject ID” and ”treatment group” and where applicable “visit ID” and/or ”visit Date” should be in all spreadsheets. Some data listings may – depending on the trial - belong to different groups, for instance ”vital signs/physical exam” usually belongs in the safety data group; however, in a hypertension trial it is likely to be an efficacy parameter. If in doubt, please ask the lead inspector:
- Study populations & conduct data – recruitment dates, analysis populations, protocol/GCP non-compliance (deviations/violations), withdrawals/completed and reasons for withdrawing/not completing/not being randomised and outcome.
- Subjects' data – demographic/covariate data (birth date, age, gender, ethnicity, race), medical history (general and related to trial objectives, e.g. tumour details, disease history/measurements), eligibility (inclusion/exclusion), consent date(s).
- Treatment data – stratification group, randomisation, treatment given (including kit number and batch number), dosing dates, dose, dose adjustments, data concerned with compliance with treatment, non-medicinal co-treatments as part of trial protocol (e.g. radiotherapy).
- Specific efficacy – raw data, repeated assessments related to efficacy, imputed values presented such that their determination from raw data can be seen (changes in parameters compared to baseline, categorisation of data to form new endpoint, clarity on last observation carried forward (LOCF) when used).
- Safety data – adverse event (AE)/ serious adverse event (SAE) – data from CRF log and also from SAE forms, repeated assessments related to safety, side effects captured in CRF (not AEs) with severity grading etc. Both data entered by site and coded data should be listed.
- Laboratory type data – sample/scan/measurement date/time (nominal and actual from CRF)/settings and other necessary details , report data time, result (from laboratories), investigator review.
- Concomitant medication data - both data entered by site and coded data should be listed.
- Subject questionnaire data (if not part of efficacy) (e.g. quality of life (QoL)).
Sponsors contract out an increasing number of tasks in clinical trials. One area where sponsors typically lack internal knowledge or resources is development of electronic systems in clinical trials, such as systems used for randomization and IMP distribution management/accountability (Interactive Response Technology (IRT)) and/or clinical trial data capture (eCRF and ePRO systems).
During inspections of commercial as well as academic trials, an increasing amount of deviations from good clinical practice (GCP) standards have been identified by the inspectors in view of sub-standard contractual arrangements and related procedures. This Q&A focuses on some areas where deviations are being given with an increased frequency and/or other deviations that inspectors wish to highlight to stakeholders.
Special consideration should be given on training and quality systems. Experience suggests that vendors accepting tasks on electronic systems are frequently knowledgeable on IT systems and sometimes on data protection legislation, but not necessarily on GCP requirements, quality systems, etc. This Q&A should be read together with Q&A #2, which contains more general considerations on how contracting should be addressed. The examples of deviations are described as bullet points under the following headings: status of contracts, distribution of delegated tasks, standards to be followed, audits and inspections, serious breaches, compliance with the protocol, output, and exemptions.
Status of contracts
The following contract-related issues have been identified by inspectors in the context of clinical trial inspections:
- Missing contracts or only draft contracts in place.
- Contracts that were not in place at the time when the delegated tasks were initiated.
- Contracts that were not maintained/updated.
- Contracts that were expired and had not been renewed as appropriate.
Distribution of tasks
Due diligence should be exercised from the sponsor in order to ensure that the distribution of tasks is clearly documented and agreed by the vendor, and that each party has the control and access to the data and information that their legal responsibilities require.
Inspectors have observed a lack of clarity with regard to:
- which tasks were defined in the contract (tasks are sometimes partially described or not described at all);
- which party is responsible for carrying out certain task regarding generating, maintaining and archiving the relevant sections of Trial Master File (emails, meeting minutes, system documentation like trial specific validation documents including documentation for user acceptance testing, specific codings, SOPs, etc.). Inspectors have seen incomplete documentation provided to the sponsor or documents that have been lost due to a lack of clarity concerning the duty of document retention;
- details concerning the retention and sponsor access to non-trial specific documentation; for example, software/system validation documents, vendor SOPs, training records, issues log/resolutions in Helpdesk/IT Ticket system, etc;
- investigator's control of their data and ownership of the data;
- location of data storage and control of this, for example use of Cloud;
- addressing potential system “down-time” and the preparation of contingency plans.
- The possibility of sub-contracting by the vendor is not always defined, including how the sponsor maintains oversight of contracted activities.
- The clinical trial applications are frequently incomplete regarding information on contracting out e-data capture and/or randomisation.
Standards to be followed
The following issues have been observed by inspectors regarding certain standards to be adhered to by the vendor.
- It is unclear/not mentioned to which standard the vendor will conduct its delegated sponsors' tasks, e.g. current legislation, ICH GCP, etc.
- Some vendors are more focused on data protection legislation than GCP, which is reflected in standard contracts.
Where the vendor fails to formally agree to comply with the applicable national and EU legislation related to the conduct of clinical trials, as well as with GCP requirements, the sponsor should consider whether the use of the vendor is appropriate for the clinical trial.
Audits and inspections
It is sometimes not stated that the sponsor should have access to conduct audits at the vendor site and that the vendor site could be subject to inspections (national and international authorities) and shall accept these.
Reporting of “serious breaches” of GCP/Trial Protocol is already a legal requirement in certain Member States. Once the Clinical Trial Regulation (EU) No 536/2014 will apply, this requirement will become applicable in all Member States, and the EU portal is currently being set up to handle future notification of serious breaches in accordance with the new Regulation.
It is frequently not specified in the contract that the vendor should report potential serious breaches to the sponsor (for assessment and onward reporting) and reporting timescales for such reports are missing.
Compliance with the protocol
The protocol is part of specification for IRT/eCRF build and therefore should be consistent with the National Competent Authority (NCA) and Research Ethics Committee (REC) approved protocol. Some contracts reviewed had inconsistencies between the protocol and the wording of the contract. Examples have also been seen where contracts referred to the version of the protocol when the contract was signed, however there was no contractual requirement to cover the vendor obtaining any subsequent changes. There is a risk that the vendor could implement changes to the eSystem based on protocol amendments sent by the sponsor that have not been approved by the CA and REC. The contract or the vendor procedures should address how this would be prevented.
In terms of output generated from the clinical trial, the following observations have been made by inspectors:
- Information is often missing about agreed output during and after the trial. Output which in some cases has not been provided to the sponsor includes: metadata, specific types of queries, audit trails on CRF data, history and status of changes to users and their access rights, description of format for delivery of the complete database to sponsors, delivery to investigators, TMF delivery, etc. On several occasions it has been seen during inspections that pdf flat files (e.g. the audit trails) have been delivered, which did not facilitate the production of a dataset, which could be needed in an inspection.
- Arrangements about decommissioning of the database are not always clear, including the possibility to restore the database to its full functionality for instance for inspection purposes. This has resulted in a difference in how the system can be inspected if it occurred during the live phase of the trial compared to when the trial ended (for example, obtain access to the audit trial and exports of it as datasets).
- Arrangements to ensure the independent investigator copy of the data and to revoke investigator access to data were frequently not described.
It is important to be aware of any exemptions in the contract regarding specific functionalities of the data collection system.
For example, contracts stating, that a data collection system cannot be used in the handling of e.g. serious adverse events, although the same system was actually used for exactly that purpose (i.e. autogenerating emails to safety departments etc.) have also been noted by the inspectors.
This Q&A should be read in conjunction with the 'Reflection paper on expectations for electronic source data and data transcribed to electronic data collection tools in clinical trials'- EMA/INS/GCP/454280/2010 and any further updates of this guidance, and it aims at addressing the situation where a sponsor is using a system (as intended) from a vendor, including the built-in possibilities for configuration.
The system in question may be a system validated by the supplier, but installed at the sponsor, or a system provided as software-as-a-service (SaaS or cloud solution).
Different requirements will apply in cases where the sponsor is changing/adding functionalities to the system.
Today, in clinical trial settings, the use of electronic systems e.g. for data collection, data management, safety data collection and evaluation, treatment allocation and trial management has proved to be more the standard than the exception. A considerable number of electronic Case Report Forms and applications for e.g. collecting Patient Related Outcome or Clinical Outcome Assessment are provided by, or purchased from, vendors and customized to varying degrees. GCP inspectors receive an increasing amount of questions from the sponsors, and deviations are given during GCP inspections, regarding the level of validation/qualification needed to be performed by a sponsor when using a system that has already been (or is supposed to have been) validated by the supplier.
According to ICH E6 (R2), 5.2.1., the ultimate responsibility for the quality and integrity of the trial data always resides with the sponsor, and according to ICH E6 R2 5.5.3.a, the sponsor should ensure and document that the electronic data processing system(s) conforms to the sponsors established requirements for completeness, accuracy, reliability, and consistent intended performance (i.e. validation).
According to ICH E6 (R2), 1.65., Validation of Computerized Systems is a process of establishing and documenting that the specified requirements of a computerized system can be consistently fulfilled from design until decommissioning of the system or transition to a new system.
Further, it is specified, that the approach to validation should be based on a risk assessment that takes into consideration the intended use of the system and the potential of the system to affect human subject protection and reliability of trial results. This risk-based approach should be applied when reading the text below. The risk assessment should be justified by the sponsor and documented.
The sponsor is ultimately responsible for the validation of the clinical trial processes which is supported by electronic systems. The sponsor may rely on qualification documentation provided by the vendor if the qualification activities performed by the vendor have been assessed as adequate, but may also have to perform additional qualification/validation activities based on a documented risk assessment.
The conditions for a sponsor to use the vendor's qualification documentation include, but are not limited to, the following:
- the sponsor has a thorough knowledge about the vendor's quality system and qualification activities, which will usually be obtained through an in-depth assessment/audit;
- an assessment/audit has been performed by qualified staff, with sufficient time spent on the activities and with cooperation from the vendor;
- an assessment/audit has gone sufficiently deep into the activities and that a suitable number of examples for relevant activities have been looked at (and documented);
- the assessment/audit report has documented the vendor's qualification documentation to be satisfactory or that shortcomings can be mitigated by the sponsor – e.g. that the sponsor is performing part of the qualification;
- the sponsor, or where applicable the CRO performing these activities for the sponsor, has a detailed knowledge about the qualification documentation and can navigate in it and explain the activities as if they had performed the activities themselves;
- when required during an inspection, the qualification documentation is made available to the inspectors in a timely manner irrespective of whether it is provided by the sponsor, CRO or the vendor.
- both the sponsor and the vendor establish full configuration management for qualification and production environments and that the sponsor can fully account for any differences between the vendor's validation environment and the sponsor's production environment and subsequently, justify any differences that are considered insignificant. If not, the qualification effort potentially does not justify the use of the system.
- the sponsor has performed an Installation Qualification/Performance Qualification where the system depends on trained users.
Sponsors and vendors should be aware that if the electronic systems are used for generating/handling relevant clinical trial data or maintain control and oversight of clinical trial processes, during GCP inspections documentation regarding the qualification process and any other relevant documentation on the e-system maintained at the sponsor level, as well as on the vendor level, could be inspected.
Documentation regarding the validation of processes and qualification of systems is considered essential by inspectors and it is likely to be requested during inspections. This is irrespective of whether or not the sponsor has contracted out activities related to electronic systems and whether the sponsor choses to consider as an audit the above mentioned assessment of vendor systems/processes/documentation . GCP inspectors do not consider the documentation/report of these activities as an audit report that falls under ICH E6 5.19.3 (d).
The question is often raised on whether it is acceptable to carry out some clinical trial procedures, for example, to dispense and/or administer the IMP (e.g. i.v. infusions) or perform blood samplings to the subjects, at their home reducing the burden of travelling to the clinical trial site.
The GCP-IWG is of the opinion that the ICH-GCP guideline and applicable EU laws do not prohibit such practice, but it should be clear who has the responsibility for all aspects of subject protection and data reliability and robustness and the procedures in place should ensure that the rights, safety, dignity and well-being of subjects are being protected and the data generated are credible and accurate. In addition, national legislation regulations (see also below) should be taken into account for aspect such as dispensing and/or administering of IMP or blood sampling. For example, the direct shipment of IMPs to the patient’s home is not allowed by national legislation in some of the EU Member States and where it is allowed, still considerations should be made in relation to the patient confidentiality and the process followed should be checked against national requirements before any shipments are made.
The GCP-IWG considers that performing any practice at the subjects’ facilities and not at the clinical trial site should be avoided as much as possible and applied only if in compliance with national legislation and when duly justified. Hence, the GCP-IWG agreed on the following points:
- The clinical condition of the patient and/or the disease treated should clearly justify that certain activities are conducted at subjects’ home with the scope of minimizing the discomfort for the patient (i.e. in case the subject/patient is obliged to stay in the bed, motor difficulties, procedures that could be hard for the subject to be performed by themselves or by their caregiver).
- The subjects should not be exposed to higher risks than those foreseen for the same procedure applied in a health care establishment. Therefore, a documented risk assessment is expected before the implementation of the procedure and the lack of availability of equipment and facilities (i.e. Emergency Department or Intensive Care Unit) should be carefully considered.
- The procedure should be clearly described in the clinical trial protocol and related informed consent form and approved by the Competent Authority and Ethics Committee.
- A contract/written agreement should be in place between the Institution/Hospital/Investigator and the single individual(s) or the organization which will provide the service/personnel (see Q&A about third parties contract).
- The personnel appointed for the procedure should be educated and qualified for the activities according to applicable national law and specifically trained.
- The personnel appointed for the procedure should be identified and their tasks should be documented on the contract/delegation log; the Principal Investigator remains ultimately responsible for the conduct of the trial.
- Tasks related to medical decisions (i.e. protocol specified medical procedures, AE/SAE assessment, changes in medication, etc.) should remain the responsibility of a qualified physician.
- Effective lines of communication between the Principal Investigator and the personnel who manage the patients at home should be established in advance and described in the clinical trial protocol (or related specific document) to guarantee that the PI is constantly kept informed; in this context there should be specific consideration in relation to the protection of patient safety.
- The activities conducted at subjects’ homes should be adequately documented; source documentation should be part of the investigators source documents and could be retained at the subjects’ home just for the time required by the procedure, providing that any source documentation will be transferred to the site according to trial management procedures.
The sponsor of a clinical trial may, in particular cases, consider necessary to provide the investigational site with personnel to be involved directly in the conduct of the clinical trial. This is usually done by the Sponsor in order to provide additional resource to the trial site or personnel with particular experience or skill to conduct specific procedures of the trial. This personnel may consist of single individuals or of people belonging to a contracted company/organization. In both cases this personnel (“contracted personnel”) is only employed for the purpose of the clinical trial under the responsibility of the investigational site/Principal Investigator/Institution.
Particular consideration should be made when the “contracted personnel” is involved not only in administrative procedures but also in procedures that require direct and practical management of trial subjects which are tasks under the exclusive responsibility of the Principal Investigator.
The GCP-IWG recognises that a clarification about this practice is required to avoid misinterpretation of the requirements and non-compliance and in order to guarantee clear separation of roles and responsibilities between investigator and Sponsor and ensure their independence, in accordance with ICH-GCP principles.
In the recent revision of ICH-GCP (R2) the following points were added regarding this practice:
4.2.5 The investigator is responsible for supervising any individual or party to whom the investigator delegates trial-related duties and functions conducted at the trial site.
4.2.6 If the investigator/institution retains the services of any individual or party to perform trial-related duties and functions, the investigator/institution should ensure this individual or party is qualified to perform those trial-related duties and functions and should implement procedures to ensure the integrity of the trial-related duties and functions performed and any data generated.
Although the Sponsor can contract directly some activities belonging to the Institution/Hospital e.g centralized analysis, archiving or central reading of images, the Sponsor cannot delegate tasks related to the medical care of the subjects that are specific of the Investigator (e.g. IMP dispensing/administration, AE/SAE evaluation), because the Investigator is responsible for all the trial medical activities. For this type of tasks, even if the Sponsor may need to be involved in the process of selection of the organization providing services and/or personnel (e.g. because the Institution and the clinical investigator site do not have resources for third parties selection), the contractual arrangements should not be made directly between the organization and the Sponsor.
A contract/written agreement should be in place between the Institution/Hospital/Investigator and the single individual(s) or the organization which will provide the service/personnel. The contract between the Sponsor and the Institution/Hospital/Investigator should mention the involvement of this external organization or personnel. The contract should specify that the investigator is responsible for the oversight of the personnel of the external organisation.
The involvement of external parties should be submitted to and approved by the Ethics Committee before the start of the activities of “contracted personnel”, as required by local regulations.
In particular on contracting an individual or party to perform trial-related duties and functions the following points should be fulfilled:
- Considerations should be made about the protection of subject confidentiality and the Informed Consent Form should reflect this point.
- The personnel appointed for the procedure should be identified and its tasks should be documented on the contract/delegation log.
- In general, relationship and communications between Principal Investigator and organization or personnel should be independent from the Sponsor and should not go through the Sponsor in order to guarantee the independence of clinical trial conduct.
Expectations of European Union (EU) competent authorities on the use of electronic trial master files
e-TMFs can be acceptable to regulatory authorities if they meet the requirements for TMFs that are described in Directive 2005/28/EC and the related guidance in volume 10 of the rules governing medicinal products in the European Union. For the purposes of GCP inspection (and audit), the following attributes apply:
- The e-TMF should allow review in an efficient manner, analagous to that possible with paper TMFs. Such a review should not take longer to access than for a paper TMF. (Efficient, straightforward navigation and opening of documents permitting searching and browsing (analogous to leafing through a paper file).
- Inspectors/auditors should have direct access to the e-TMF and the documents held in the e-TMF (the live system, not a copy) to allow direct searching.
- Documents held on an e-TMF should be evidently authentic, complete and legible copies of the original documents.
- The e-TMF system should have validated methods for preventing any changes being made to the TMF documents, this includes the process of transferring from original media to the electronic medium.
- The process for transferring original TMF documents to e-TMF (or other media) should be robust and have been validated to prevent failure of transfer the entire content of the original TMF without loss ( i.e. there should be a demonstrable 1:1 mapping between the content of the original TMF and the e-TMF ).
Documents on e-TMF should remain complete and legible in all aspects giving information about the way the document was prepared. This holds especially for contracts and forms completed by hand. Transfer to e-TMF should not (be used to) conceal any physical change to the document such as physical cut & paste to remove or add items, use of correction fluid etc.
It is helpful if the e-TMF has:
- A folder structure to allow easy identification of TMF sections.
- A folder/file naming convention that readily identifies what each file/document is, so inspectors/auditors do not have to open numerous documents to locate those they need.
- The ability to open more than one document at a time to allow comparison (so size of screens or double screens important).
- The ability to provide access to the same type of document across all studies/sponsors/product etc (i.e. if inspector needs to review documents for all/some selected studies/sites).
For the future, it would help if e-TMFs were available through secure internet links. This would help to avoid some unnecessary travel when accessing the TMF. This approach has advantages over supplying e-TMFs by e-mail, DVD etc., in that only one version of the e-TMF needs to exist, which can be continually updated for ongoing trials.
- Assisting the development of virtual inspections.
- Improving the efficiency of the inspection process (and lowering the carbon footprint of trial management, inspection and audit).
A variety of records is generated and maintained relating to the healthcare of clinical trial subjects (whether study subjects or healthy subjects). Some of these are general and relate to the general healthcare of the study subject before, during and after the trial. Others are specific to the trial. A clinical trial as a scientific undertaking requires careful record-keeping to ensure that data are collected and reported in an accurate and complete manner. In addition regulations and guidelines have established processes including investigator review, monitoring, auditing and inspection, in order to check and control the accuracy and completeness of the data. GCP, ethical requirements and medical standards require that each study subject is cared for and this duty to the individual is put above the more general scientific needs.
There are national, professional, local, or institutional requirements either in law, various forms of guidance, rules, or established practice which define many requirements for the maintenance of records in the course of normal study subject care. Any requirements that may arise as a consequence of the conduct of clinical trials can only be an addition and not a substitute for these, since the conduct of a clinical trial should never diminish the standard of care.
Many of those involved in clinical research ask questions about what should be documented, when, where, by whom and for what reason.
The purpose of this document is to set out some of the main elements of this study subject record-keeping in the clinical trial context, in order to assist those involved in clinical research to understand why such records are kept and looked for, and in order to help in planning record-keeping in specific contexts.
Taking into account the various issues outlined it is very unlikely that a CRF would ever suffice as the complete and only record of a study subject relevant to their participation in a clinical trial.
Reference documents: Note for guidance on GCP (CPMP/ICH/135/95)

What should appear in the original medical record?
- The medical record is a key element of study subject care. It ensures that an ongoing record of information relating to the study subject, visit records, test records, medical history, diagnoses, treatments etc. are available to the treating physician and his or her colleagues or peers who may intervene in the care of the study subject or take over that care. As such it has a role before, during and after the clinical trial per se.
- Any information that would routinely be expected to appear in a medical record should continue to appear there during the study to ensure the care of the study subject is maintained.
- The fact that the study subject is in a clinical trial, its identity and any specific information over and above the routine that impact on the study subject care should also appear, or be clearly referenced and readily available to the care giver.
- The medical record may also be the first place in which trial related data is recorded and as such becomes by definition the source document for that data.
- It may also be the main point of information on medical history for the purposes of the study, even if that information was originally recorded elsewhere.
- The medical record should provide sufficient baseline information to permit the investigator to enrol the study subject in the trial with due recognition of the needs of medical care and in compliance with the protocol.
- The medical record is also the common point of confirmation of study subject identity and demographics.
What purposes does the medical record serve in the context of the clinical study?
- Study subject care
- Source document
- Corroborating/supporting document – the medical record is generally a document with some legal status, open to degrees of peer review, and completed in many cases by several people. As such it serves as an important supporting document to corroborate data reported to the sponsor in the CRF.
- For example identity and patient existence, demographics, medical history, diagnosis, participation in the clinical trial, IMP and concomitant medication, intercurrent illness and adverse events. In addition, various protocol related measurements may appear here or in related documents (laboratory reports, ECGs, X-rays and reports etc).
- Where the protocol has described that certain data may be recorded solely in the CRF – this in general is taken to mean multiple repeat measurements, rating scales, study subject diaries.
What purpose do source documents serve?
- Prompt and accurate recording of study data.
- A source from which the CRF can be completed.
- Quality control and other verification and corroboration (monitoring, audit, inspection) of study data and study conduct/protocol/GCP compliance.
What characteristics should source data documents have?
Source documents should be:
- Available and accessible
An increased trend of clinical trial sponsors routinely requesting copies of medical records from investigator sites has been noted during GCP inspections. There may be different reasons for this, such as endpoint committee evaluation, safety committee evaluation or even remote monitoring of e.g. eligibility criteria. The medical records could be hospital notes, scans, laboratory reports etc.
There are many aspects to take into consideration when clinical trials documents containing sensitive data of patients are sent to a sponsor, or a third party working on behalf of the sponsor, and failures have been noted during inspections.
Some examples are:
- Medical records have not been redacted properly, and thus reveal to the sponsor the identity of the subject.
- Medical records sent to sponsor contained a considerable amount of data that was not to be collected as part of the clinical trial including sensitive information about the patient's family members or patient's life situation.
- Medical records have been sent via communication channels which do not guarantee an adequate level of security.
Without prejudice to the possible violation of the rules concerning the processing of personal data, it should be considered that failure to implement adequate technical and organizational measures for the protection of data could result in undermining the dignity of clinical trial subjects. It is therefore important to remind investigators and sponsors of their obligations concerning the protection of personal data in connection with the activities of clinical trials.
"The rights, safety and well-being of the trial subjects are the most important considerations and should prevail over interests of science and society", as stated in ICH GCP article 2.3. The guideline further states in article 2.11 that "The confidentiality of records that could identify subjects should be protected, respecting the privacy and confidentiality rules in accordance with applicable regulatory requirement(s)."
The WMA Declaration of Helsinki (64th WMA General Assembly, Fortaleza, Brazil, October 2013) is also very clear on this subject in article 24: "Every precaution must be taken to protect the privacy of research subjects and the confidentiality of their personal information."
There are also provisions in the EU data protection legislation that need to be adhered to when performing clinical trials. The current Directive 95/46/EC represents the reference text, at European level, on the protection of personal data. It sets up a regulatory framework which seeks to strike a balance between a high level of protection for the privacy of individuals and the free movement of personal data within the European Union (EU).
The Regulation (EU) 2016/679 (the General Data Protection Regulation - GDPR) on the protection of natural persons with regard to processing of personal data and free movement of such data, repealing Directive 95/46/EC, maintains the basic principles of the Directive and aims at increasing consistency in the application of data protection rules in the EU. The GDPR entered into force on 24 May 2016 and will apply from 25 May 2018.
In this context "coding", is the process of assigning to a name or other direct identifier a unique code. The process of assigning a subject identification code meets the definition of pseudonymisation described in Article 4(5) of the GDPR: "Article 4(5) GDPR - pseudonymisation' means the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organisational measures to ensure that the personal data are not attributed to an identified or identifiable natural person."
Recital 26 of the GDPR also clarifies that the personal data which have undergone pseudonymisation are information on an identifiable natural person and as such, they are considered personal data and hence fall under the scope of the GDPR as opposed to anonymous information, as described in the same recital: "Namely information which does not relate to an identified or identifiable natural person or to personal data rendered anonymous in such a manner that the data subject is not or no longer identifiable" which falls outside the scope of the GDPR."
Thus, as long as there is a link between the subject identification code and the subjects' identity at the clinic level, such data should be regarded as "pseudonymised" and thus should be handled as personal data.
The legal status of clinical trial subject data as personal data, whether coded or not, needs to be taken into account by investigators and sponsors, or a third party working on behalf of the sponsor, at all times and in particular when the data are transferred to other parties. This refers to e.g. CRF data as well as redacted copies of medical records. Below are some important factors to take into consideration:
- The handling of and access to medical records are subject to national regulations in the respective Member States. These regulations may include rules on how medical records can be viewed by monitors for source data verification on site (e.g. within the clinical environment).
In addition they may also refer to the extent and under which circumstances records can be provided to sponsors, or third parties working on their behalf, outside the clinical environment. These national regulations need to be followed by the clinics when sharing medical records with a sponsor, or a third party working on behalf of the sponsor, within the scope of clinical trials.
- There should be procedures in place at the investigator site to redact copies of medical records in an appropriate way, in order to protect patients' identity, before transferring them outside the clinical environment to a sponsor, or a third party working on behalf of the sponsor.
- Adequate security measures by the data controller, which are relevant to the process, including pseudonymisation and redaction, should be applied when transferring personal data (redacted copies of medical records, SAE forms, CRFs, etc.) from investigator sites to a sponsor, or a third party working on behalf of the sponsor. The sponsors need to take appropriate security measures and provide organizational and technical measures that fulfil the requirements of the data protection regulation.
- Due to the sensitive type of information recorded in medical records, the extent to which sponsors request these data should be ethically and scientifically justified, and limited to specific critical information. Any planned collection of redacted copies of medical records by the sponsor should be described in the protocol, or related documents, and should be explicit in the patient information. Extensive centralised collection of copies of medical records should not be used as substitute for source data verification involving medical records at the investigator site.
Overall, it is expected that during and after the conduct of clinical trials patients' integrity, involving handling of personal data, is respected, and that regulations governing both clinical trials and data protection are fulfilled.
