3. NOTIFICATION OF AMENDMENTS AND RELATED MEASURES
3.1. Legal basis and scope
105. Article 10(a) of Directive 2001/20/EC reads as follows:
‘After the commencement of the clinical trial, the sponsor may make amendments to the protocol. If those amendments are substantial and are likely to have an impact on the safety of the trial subjects or to change the interpretation of the scientific documents in support of the conduct of the trial, or if they are otherwise significant, the sponsor shall notify the competent authorities of the Member State or Member States concerned of the reasons for, and content of, these amendments and shall inform the ethics committee or committees concerned in accordance with Articles 6 (Ethics Committee) and 9 (Commencement of clinical trial).’
106. In view of the identical legal consequences of an amendment that is ‘substantial and likely to have an impact on the safety of the trial subjects or to change the interpretation of the scientific documents in support of the conduct of the trial’ and an amendment that is ‘otherwise significant’, the term ‘substantial amendment’ used in this guidance refers to both types of amendments.
107. Notification/submission of information (1) is only obli- gatory if the amendment is a substantial amendment. Directive 2001/20/EC does not require notification, nor immediate submission of information of non-substantial amendments. Neither national competent authorities of the Member State concerned, nor its Ethics Committee can oblige the sponsor to submit non-substantial amendments. In this regard, the rules for non-substantial amendments (cf. Section 3.6) apply.
3.2. The notion of ‘amendment’
108. The following changes do not count as an ‘amendment’ as
referred to in Article 10(a) of Directive 2001/20/EC:
— a change to the documentation submitted to the national competent authority during the ongoing assessment of the request for authorisation by the national competent authority (for these aspects see Section 2.1.4.2), and
— a change to the documentation submitted to the Ethics Committee during the ongoing assessment of the request for authorisation by the Ethics Committee.
109. Article 10(a) of Directive 2001/20/EC refers only to amendments to the approved protocol. This is to be understood as encompassing all documentation submitted in the context of the approved protocol.
110. The annual safety report (ASR) in accordance with Article 17(2) of Directive 2001/20/EC is not per se an amendment and thus does not have to be notified as a substantial amendment to the national competent authority of the Member State concerned. However, the sponsor has to verify whether the data presented in the ASR requires a change to the documentation submitted with the request for authorisation of a clinical trial. If this amendment is substantial, the rules for notification of substantial amendments apply to these changes.
111. A change of the contact person or in the contact details of the contact person (e.g. a change of e-mail or postal address) is not considered as an amendment, if the sponsor and legal representative remain identical. However, the sponsor should ensure that the national competent authority of the Member State concerned is aware of this change as soon as possible, in order to allow the national competent authority to exercise its supervisory function.
3.3. The notion of ‘substantial’
112. Amendments to the trial are regarded as ‘substantial’ where they are likely to have a significant impact on: the safety or physical or mental integrity of the clinical trial participants, or the scientific value of the trial.
113. In all cases, an amendment is only to be regarded as ‘substantial’ when one or both of the above criteria are met.
114. It is up to the sponsor to assess whether an amendment is to be regarded as ‘substantial’. This assessment is to be made on a case-by-case basis in view of the above criteria. While the responsibility for this assessment lies with the sponsor, in cases where the sponsor consults the national competent authority advice should be given without delay and free of charge.
115. In applying these criteria, however, care has to betaken to avoid over-reporting. In particular, not every change to the clinical trial application form is by default to be considered as a ‘substantial’ amendment.
116. The annual update of the IB in accordance with Article 8 of Directive 2005/28/EC is not per se a substantial amendment. However, the sponsor has to verify whether the update relates to changes which are to be considered as substantial. In that case, the rules for notification of substantial amendments apply to the change.
117. The sponsor should assess also whether the combination of substantial amendments lead to changes of the clinical trial to an extent that it has to be considered as a completely new clinical trial, which would then be subject to a new authorisation procedure.
3.4. Examples
118. In view of these criteria the following examples should serve as guidance for the case-by-case decision of the sponsor. These examples relate only to the aspects assessed by the national competent authority of the Member State concerned. For aspects considered by the Ethics Committee, reference is made to the Commission guidance based on Article 8 of Directive 2001/20/EC.
119. With regard to the protocol, the following is a non- exhaustive list of amendments that are typically ‘substantial’: (a) change of main objective of the clinical trial; (b) change of primary or secondary endpoint which is likely to have a significant impact on the safety or scientific value of the clinical trial; (c) use of a new measurement for the primary endpoint; (d) new toxicological or pharmacological data or new interpretation of toxicological or pharmacological data which is likely to impact on the risk/benefit assessment; (e) a change in the definition of the end of the trial, even if the trial has in practice already ended; (f) addition of a trial arm or placebo group; (g) change of inclusion or exclusion criteria, such as changes to age range, if these changes are likely to have a significant impact on the safety or scientific value of the clinical trial; (h) reducing the number of monitoring visits; (i) change of a diagnostic or medical monitoring procedure which is likely to have a significant impact on the safety or scientific value of the clinical trial; (j) withdrawal of an independent data monitoring board; (k) change of IMPs; (l) change of dosing of IMPs; (m) change of mode of administration of IMPs; (n) a change of study design which is likely to have a significant impact on primary or major secondary statistical analysis or the risk/benefit assessment.
IMPs is short for Investigational Medicinal Products
120. With regard to the protocol, the following is a non- exhaustive list of amendments that are typically not ‘substantial’: (a) changes to the identification of the trial (e.g. change of title, etc.); (b) the addition/deletion of exploratory/tertiary endpoints; (c) a minor increase in the duration of the trial (< 10 % of the overall time of the trial); (d) an increase in duration of > 10 % of the overall time of the trial, provided that: the exposure to treatment with the IMP is not extended; the definition of the end of the trial is unchanged, and monitoring arrangements are unchanged; (e) a change in the number of clinical trial participants per trial site, if the total number of participants in the Member State concerned is identical or the increase/ decrease is insignificant in view of the absolute number of participants; (f) a change in the number of clinical trial participants in the Member State concerned, if the total number of participants is identical or the increase/decrease is insignificant in view of the absolute number of participants; (g) a change in the documentation used by the research team for recording study data (e.g. case report form or data collection form); (h) additional safety monitoring which is not part of an urgent safety measure but is taken on a precautionary basis; (i) minor clarifications to the protocol; (j) correction of typographical errors.
3.4.2. Amendments as regards the IMPD
121. With regard to changes in the IMPD, guidance is contained in Chapter 8 of the Guideline on the requirements to the chemical and pharmaceutical quality documentation concerning investigational medicinal products in clinical trials (1).
3.4.3. Amendments as regards the IB
122. With regard to the IB, the following is a non-exhaustive list of amendments that are typically ‘substantial’: (a) new toxicological or pharmacological data or new interpretation of toxicological or pharmacological data of relevance for the investigator; (b) changes to the reference safety information for the annual safety report.
3.4.4. Amendments as regards other initial documents supporting the request for authorisation of the clinical trial
123. With regard to other initial documents, the following is a non-exhaustive list of amendments that are typically ‘substantial’: (a) a change of sponsor or the sponsor’s legal representative; (b) the revocation or suspension of the IMP’s marketing authorisation.
124. With regard to other initial documents, the following is a list of amendments that are typically not ‘substantial’: (a) any change of persons other than the sponsor or his legal representative, for example applicant, clinical research associates (CRAs) who monitor the clinical trial for the investigator, and clinical research organ- isations (CROs) (note that the responsibility vis-à-vis the national competent authority for the clinical trial is always with the sponsor or his legal representative); (b) any change in the contact details of persons referred to in the documentation (see, however, Section 3.2 as regards contact details of the contact person); (c) changes to the internal organisation of the sponsor or of the persons to whom certain tasks have been delegated; (d) changes in the logistical arrangements for storing/ transporting samples; (e) change of technical equipment; (f) addition or deletion per se of another Member State or third country concerned.
3.5. Who should be notified?
125. Substantial amendments may relate to information relevant for assessment by the national competent authority, the Ethics Committee, or both.
126. For substantial amendments to information that is assessed only by the national competent authority of the Member State concerned, the sponsor should only notify the amendment to the national competent authority.
127. For substantial amendments to information that is assessed, according to Directive 2001/20/EC, only by the Ethics Committee of the Member State concerned, the sponsor should only notify the amendment to the Ethics Committee. This is in particular of relevance for the information relating to:
— the clinical trial site (Article 6(3)(f) of Directive 2001/20/EC),
— the written information to be given to the clinical trial participant in order to obtain informed consent (Article 6(3)(g) of Directive 2001/20/EC), and2001/20/EC).
128. These aspects are addressed in the separate Commission guidance based on Article 8 of Directive 2001/20/EC.
129. In the case of substantial amendments that affect information assessed by both the national competent authority and the Ethics Committee of the Member State concerned, the sponsor should submit the notifications in parallel.
130. There is no need to notify ‘for information only’ substantial amendments to one body (national competent authority or Ethics Committee), if this information is assessed by the respective other body.
131. In practice, it is necessary that the national competent authority and the Ethics Committee in the Member State concerned communicate with each other in order to ensure the exchange of expertise or information. This may be in particular relevant, for example, for:
— assessing scientific information requiring specific expertise,
— ensuring effective inspections of clinical trials sites, and
— updating relevant information in EudraCT.
3.6. Non-substantial amendments
132. The sponsor does not have to notify non-substantial amendments to the national competent authority or the Ethics Committee. However, non-substantial amendments should be recorded and contained in the documentation when it is subsequently submitted, for example in the subsequent notification of a substantial amendment. This is of particular relevance for the Clinical Trial Application Form: This form should be updated in its entirety at the occasion of a substantial amendment. Documentation of non-substantial amendments should also be available on request for inspection at the trial site or the sponsor premises as appropriate.
3.7. Format and content of notification
133. The notification of a substantial amendment should include the following:
(a) a signed cover letter, including:
— in its subject line the EudraCT number and the sponsor protocol number (if available) with the title of the trial and the sponsor’s amendment code number allowing unique identification of the substantial amendment. Care should be takento use the code number consistently;
— identification of the applicant;
— identification of the amendment (sponsor’s substantial amendment code number and date). One amendment could refer to several changes in the protocol or scientific supporting documents;
— a highlighted indication of any special issues related to the amendment and indication where the relevant information or text is in the original application dossier;
— identification of any information not contained in the Amendment Notification Form that might impact on the risk to trial participants;
— where applicable, a list of all affected clinical trials with EudraCT numbers and respective amendment code numbers (see above);
(b) the Amendment Notification Form, as amended, which is published in Volume 10 of EudraLex
The Rules Governing Medicinal Products in the European Union. Only this Amendment Notification Form should be used;
(c) a description of the amendment:
— an extract from the amended documents showing previous and new wording in track changes, as well as the extract only showing the new wording;
— notwithstanding the previous point, if the changes are so widespread or far-reaching that they justify an entire new version of the document, a new version of the entire document. In this case, an additional table should list the amendments to the documents. In this list, identical changes can be grouped.
The new version should be identified with the date and an updated version number.
(d) supporting information including, where applicable:
— summaries of data,
— an updated overall risk/benefit assessment,
— possible consequences for subjects already included in the trial,
— possible consequences for the evaluation of the results;
(e) if a substantial amendment involves changes to entries on the clinical trial application form, a revised copy of the XML file incorporating amended data. If the form is not submitted via a telematics system, the fields affected by the substantial amendment should be highlighted in the revised form (3).
134. Where a substantial amendment affects more than one clinical trial of the same sponsor and the same IMP, the sponsor may make a single notification to the national competent authority/Ethics Committee of the Member State concerned. The cover letter and the notification should contain a list of all clinical trials affected with their EudraCT numbers and respective amendment code numbers. If the substantial amendment involves changes to several clinical trial application forms, all forms should be updated (see Section 3.7).
3.8. Time for response, implementation
135. Article 10(a), second and third subparagraph, of Directive 2001/20/EC reads as follows:
‘On the basis of the details referred to in Article 6(3) and in accordance with Article 7, the Ethics Committee shall give an opinion within a maximum of 35 days of the date of receipt of the proposed amendment in good and due form. If this opinion is unfavourable, the sponsor may not implement the amendment to the protocol.
If the opinion of the Ethics Committee is favourable and the competent authorities of the Member States have raised no grounds for non-acceptance of the … substantial amendments, the sponsor shall proceed to conduct the clinical trial following the amended protocol. Should this not be the case, the sponsor shall either take account of the grounds for non-acceptance and adapt the proposed amendment to the protocol accordingly or withdraw the proposed amendment.’
136. Accordingly, the Ethics Committee has to give within 35 calendar days an opinion on a valid submission of a proposed substantial amendment. If a submission is not considered as valid by the Ethics Committee, the Ethics Committee should inform the applicant of this within the first 10 calendar days of this 35-day period. The reasons should be given.
137. With regard to the national competent authority, no deadline is set in Directive 2001/20/EC., and in view of the approval time for requests for authorisation, the national competent authority are invited to respond within 35 calendar days of receipt of the valid notification of an amendment. Validation of the submission is included in this period. If a submission is not valid (for example, the dossier does not contain the documentation required according to this guidance), the national competent authority are invited to inform the applicant of this within the first 10 calendar days of this 35-day period. The reasons should be given. This response time may be extended if such extension is justified in view of the nature of the substantial amendment, for example if the national competent authority has to consult an expert group or committee. In such cases, the national competent authority should notify the sponsor of the duration of the extension and its reasons. If the national competent authority states that it raises no grounds for non-acceptance, the sponsor can implement the changes, even if fewer than 35 days have elapsed since the filing of the substantial amendment.
138. For amendments submitted to either the Ethics Committee alone or to the national competent authority alone, the sponsor may implement the amendment when the Ethics Committee opinion is favourable or the competent national authority has raised no grounds for non- acceptance.
139. Up until then, the trial can continue on the basis of the original documentation, unless the rules for urgent safety measures apply.
140. Applicants should be aware that these procedures are intended to ensure rapid and efficient processing of substantial amendments. Against this background, unsatis- factory documentation is likely to lead to non-acceptance of the substantial amendment. Non-acceptance does not prejudice the applicant’s right to resubmission.
141. Upon approval, it is the sponsor’s responsibility to ensure communication of the changes to the investigators.
3.9. Notification of urgent safety measures
142. Article 10(b) of Directive 2001/20/EC reads as follows:
‘Without prejudice to point (a), in the light of the circum- stances, notably the occurrence of any new event relating to the conduct of the trial or the development of the investigational medicinal product where the new event is likely to affect the safety of the subjects, the sponsor and the investigator shall take appropriate urgent safety measures to protect the subjects against any immediate hazard. The sponsor shall forthwith inform the competent authorities of those new events and the measures taken and shall ensure that the Ethics Committee is notified at the same time.’
143. Examples of urgent safety measures are if, for reasons of safety of the clinical trial participants, a trial is temporarily halted (see Section 3.10) or additional monitoring measures are set up.
144. Urgent safety measures may be taken without prior notifi- cation to the national competent authority. However, the sponsor must inform ex post the national competent authority and the Ethics Committee of the Member State concerned of the new events, the measures taken and the plan for further action as soon as possible. Where the initial contact is by telephone, this should be followed up, for reasons of traceability, by fax or e-mail. It should be followed by a written report.
145. The ex post notification of urgent safety measures is independent of the obligation to:
— notify substantial amendments (see above),
— notify early termination of the trial within 15 days in accordance with Article 10(c) of Directive 2001/20/EC (see below, Section 4.2.2), and
— notify adverse events and serious adverse reactions in accordance with Articles 16 and 17 of Directive 2001/20/EC.
3.10. Temporary halt of a trial
146. A temporary halt of a trial is a stoppage of the trial which is not envisaged in the approved protocol and where there is an intention to resume it.
147. A temporary halt can be:
— a substantial amendment, or
— part of an urgent safety measure as referred to in Article 10(b) of Directive 2001/20/EC. In this case, the notification of the temporary halt of a trial should be made immediately and, at the latest, in accordance with the deadline set out in Article 10(c), second sentence, of Directive 2001/20/EC, within 15 days from when the trial is temporarily halted.
148. The reasons and scope, e.g. stopping recruitment or inter- rupting treatment of subjects already included, should be clearly explained in the notification (in case of substantial amendment, see Section 3.7) or in the ex post information (in case of urgent safety measures, see Section 3.9).
149. The restart of the trial should be treated as a substantial amendment providing evidence that it is safe to restart the trial.
150. If the sponsor decides not to recommence a temporarily halted trial he should notify the national competent authority of the Member States concerned within 15 days of his decision in accordance with Article 10(c), second sentence, of Directive 2001/20/EC (see Section 4.2).
3.11. Suspension/prohibition of a clinical trial by the national competent authority in case of doubts about safety or scientific validity
151. Article 12(1) of Directive 2001/20/EC reads as follows:
‘Where a Member State has objective grounds for considering that the conditions in the request for
authorisation referred to in Article 9(2) are no longer met or has information raising doubts about the safety or scientific validity of the clinical trial, it may suspend or prohibit the clinical trial and shall notify the sponsor thereof.
Before the Member State reaches its decision it shall, except where there is imminent risk, ask the sponsor and/or the investigator for their opinion, to be delivered within one week.
In this case, the competent authority concerned shall forthwith inform the other competent authorities, the Ethics Committee concerned, the Agency and the Commission of its decision to suspend or prohibit the trial and of the reasons for the decision.’
152. If the trial is terminated following a suspension, the rules on end of trial notification apply (see below, Section 4.2).
3.12. Non-compliance with the applicable rules on clinical trials
153. Article 12(2) of Directive 2001/20/EC reads as follows:
‘Where a competent authority has objective grounds for considering that the sponsor or the investigator or any other person involved in the conduct of the trial no longer meets the obligations laid down, it shall forthwith inform him thereof, indicating the course of action which he must take to remedy this state of affairs. The competent authority concerned shall forthwith inform the Ethics Committee, the other competent authorities and the Commission of this course of action.’
154. The ‘course of action’ of the national competent authority should have a timetable for its implementation and a date when the sponsor should report back to the national competent authority on the progress and completion of its implementation.
155. The sponsor should ensure that the ‘course of action’ set by the national competent authority is immediately imple- mented and report to the national competent authority of the Member State concerned on the progress in and completion of its implementation in accordance with the timetable set.
156. The national competent authority must inform the other national competent authorities, the Ethics Committee of the Member State concerned and the Commission of the ‘course of action’.
