Public Release of Clinical Information: guidance document
Guidance documents are meant to provide assistance to industry and health care professionals on how to comply with governing statutes and regulations. Guidance documents also provide assistance to staff on how Health Canada mandates and objectives should be implemented in a manner that is fair, consistent and effective.
Guidance documents are administrative instruments. They do not have force of law and as such they allow for flexibility. Alternate approaches to the implementation of the principles, considerations and requirements described in this document may be acceptable provided they comply with relevant laws. Discussion with the relevant program area in advance is encouraged to determine whether an alternative approach meets applicable statutory or regulatory requirements.
As a corollary to the above, it is equally important to note that Health Canada reserves the right to request information or material, or define conditions not specifically described in this document. Health Canada is committed to ensuring that such requests are justifiable and that decisions are clearly documented.

1.1 Policy Objective
Health Canada's objective is to make anonymized clinical information in drug submissions and medical device applications publicly available for non-commercial purposes following the completion of Health Canada's regulatory review process, while adhering to Canada's Privacy Act.
Health Canada receives clinical information to evaluate the safety and efficacy of drugs and medical devices that are submitted for approval for sale in Canada. Providing public access to this clinical information can enable independent re-analyses of data, foster new research questions, and benefit Canadians by helping them to make informed decisions about their health.
This document is designed to help the public, industry, healthcare professionals and other stakeholders better understand the implementation of Health Canada's Public Release of Clinical Information (PRCI) initiative, including: the procedures to prepare information for release; the categories of information that continue to be subject to the definition of confidential business information (CBI) and that may be eligible for redaction; and protection of personal information.

1.3 International Alignment
Health Canada recognizes the importance of international alignment in clinical information sharing, particularly regarding the release of clinical information that is available in other jurisdictions. Its implementation of the public release of clinical information seeks to align with international best practices, where these conform with Canadian legal requirements and help to advance Canadian policy objectives. Collaboration with the clinical information publication programs of our regulatory partners will help to reduce administrative burden and promote consistency in the protection of personal information.
2. Scope and Application
2.1 General scope and application
This document applies to amendments to the Food and Drug Regulations and the Medical Devices Regulations, which came into force on February 28, 2019. These regulatory amendments specify the clinical information in drug submissions and medical device applications that cease to be confidential business information following a final regulatory decision and authorize Health Canada to publicly release this information. This guidance describes the scope of clinical information eligible for public release and the procedures to remove information that remains CBI and to protect personal information prior to public release.
The regulatory amendments apply to clinical information submitted to Health Canada in the past as well as in the future. Health Canada intends to publish on a proactive basis the information in drug submissions and medical device applications that receive a final regulatory decision following the coming into force of the regulations (new submissions). Proactive publication of this information will be phased in over four years, as described in section 3.3 of this guidance. Health Canada intends to make available on request the information in drug submissions and medical device applications that received a final regulatory decision prior to the coming into force of the regulations (past submissions).
This document does not apply to the CBI disclosure authority under section 21.1(3)(c) of the Food and Drugs Act, which permits the Minister to disclose CBI to certain persons for the purpose of protection or promotion of human health or the safety of the public. Information on this authority can be found in guidance document - Disclosure of Confidential Business Information under Paragraph 21.1(3)(c) of the Food and Drugs Act.
2.2 Clinical Information in Drug Submissions
Paragraph C.08.009.2 of the FDR describes the circumstances when clinical information within drug submissions ceases to be CBI. These are:
- the issuance of a notice of compliance (NOC),
- the issuance of a notice of non-compliance-withdrawal (NON-W), or
- the issuance of a notice of deficiency-withdrawal (NOD-W).
Paragraph C.08.009.3 of the FDR provides the Minister with the authority to disclose, without notification or consent, clinical information once it has ceased to be CBI under the above circumstances.
Clinical information for drugs is submitted under Division 8 of the FDR and is provided to Health Canada in the internationally-harmonized electronic Common Technical Document (eCTD) structure. Health Canada will release clinical information contained in eCTD modules 2.5 (Clinical Overviews), 2.7 (Clinical Summaries) and 5.3 (Clinical Study Reports). See Appendix A for greater detail. In addition, Health Canada will release clinical information in the following appendices to clinical study reports: 16.1.1 (Protocol and Protocol Amendments), 16.1.2 (Sample Case Report Forms) and 16.1.9 (Statistical Analysis Plan). See Appendix B for greater detail.
Clinical information may be found in the following drug submission types:
- New Drug Submissions (NDS)
- Supplemental New Drug Submissions (SNDS)
- Abbreviated New Drug Submissions (ANDS)
- Supplemental Abbreviated New Drug Submissions (SANDS)
- Extraordinary Use New Drug Submissions (EUNDS)
- Supplemental Extraordinary Use New Drug Submissions (SEUNDS)
Regardless of its location in a drug submission, chemistry, manufacturing, and other non-clinical information will remain subject to the FDA definition of confidential business information.
Health Canada intends to proactively publish clinical information in new drug submissions beginning in 2019. Proactive publication will be phased in by submission type, as described in section 3.3 of this guidance. Information in drug submissions not subject to proactive release is available on request.
2.3 Clinical Information in Medical Device Applications
Section 43.12 (1) of the MDR describes the circumstances when clinical information within medical device applications that is CBI ceases to be CBI. These are:
- the issuance of a medical device license,
- the issuance of a medical device license amendment, or
- the issuance of a refusal letter.
Section 43.13 of the MDR provides the Minister with the authority to disclose, without notification or consent, clinical information once it has ceased to be CBI under the above circumstances.
For Class III and IV medical devices, clinical information is currently received under section 32 (3), and (4) of the MDR. Class I and II medical devices are out of scope. Class I medical devices are exempt from device licensing. Clinical evidence for Class II medical devices is not required to be submitted upon application for a medical device licence, except in certain circumstances.
Clinical information may be found in the following medical device application types:
- Class III Medical Device Application
- Class III Medical Device Application Amendment
- Class IV Medical Device Application
- Class IV Medical Device Application Amendment
Regardless of its location in a medical device application, manufacturing and other non-clinical information will remain subject to the FDA definition of confidential business information.
Health Canada intends to proactively publish clinical information in new medical device applications beginning in 2021. Proactive publication will be phased in by application type, as described in section 3.3 of this guidance.
The table below summarizes how the regulations apply to drug submissions and medical device applications, and how Health Canada intends to implement public release of the clinical information they contain.
|Application of regulations||Implementation|
|Drug submissions||Medical device applications||Drug submissions||Medical device applications|
|New submissions/ applications||✔||✔||Begin proactive publication in 2019*||Begin proactive publication in 2021*|
|Past submissions/ applications||✔||✔||Available on request from March 20, 2019||Available on request from March 20, 2019|
* see phase-in schedule for proactive publication in section 3.3 of this guidance
3. General Guidance on Implementation
3.1 Consideration Regarding Interim Analyses
An interim analysis is defined in ICH guidance: E9: Statistical Principles of Clinical Trialsas any analysis intended to compare treatment arms for efficacy or safety, at any time prior to the formal completion of a trial.
Premature disclosure of clinical information prior to the finalization of a clinical trial risks jeopardizing the reliability of the trial data by affecting patient recruitment, biasing data collection and analysis or weakening confidence in the study conclusions. Disclosure of interim analyses will be balanced with the need to retain the scientific integrity of clinical studies.
The decision to disclose clinical information within interim analyses will be taken case-by-case based on the following considerations:
|Situation involving an interim analysis:||Clinical Study Status||Disclosure|
|An interim analysis that established clear superiority of the treatment for the condition(s) of use and that is used to stop the trial early||Clinical study is not ongoing||Interim analysis will be considered for release|
|An interim analysis of a clinical study that has been either completed or discontinued||Clinical study is not ongoing||Interim analysis will be considered for release|
|An interim analysis of an ongoing trial that, if released, may impact the integrity of the study results and possibly weaken confidence in the conclusions drawn||Clinical study is ongoing||Interim analysis will not be considered for release|
3.2 Individual Patient Records (Individual Patient Listings and Case Report Forms)
Clinical case report forms (e.g. ICH E3 16.3) are documents designed to record information on each trial subject as required by the clinical study protocol. Individual patient listings (e.g. ICH E3 16.2) include demographic data, individual efficacy response data, and listings of individual laboratory measurements by patient. As multiple records are provided for each trial participant, this information represents a large portion of a typical drug submission.
Because individual patient records include a large amount of structured and unstructured personal information, extensive modification is required to anonymize this information. Applying currently available methods for anonymization requires considerable resources and significantly reduces the research value of the information. Consequently, individual patient records will not be publicly released with other clinical information.
Researchers interested in obtaining individual patient records related to information for therapeutic products for the purpose of research or statistical analysis may do so under the Privacy Act in accordance with applicable provisions.
Adverse events and other significant participant-level results are reported in the main body of the clinical study report that is subject to release under this authority. Section 6 of this guidance sets out procedures for anonymizing personal information contained in clinical study reports prior to public release.
3.3 Implementation Schedule for the Proactive Disclosure of Clinical Information in Drug Submissions and Medical Device Applications
Health Canada plans to phase-in the proactive release of clinical information in drug submissions and medical device applications that receive a final regulatory decision following the coming into force of these regulations (new submissions). Proactive publication of this information is expected to be implemented on the following schedule:
|Stage||Proposed Phase-in||Scope of Application Types|
|1||Year 1||NDS-NAS + SNDS-c + Rx-switch|
|2||Year 2||All NDS + SNDS-c + Rx-switch|
|3||Year 3||All NDS, all SNDS & Class IV devices|
|4||Year 4||All NDS, SNDS, ANDS, SANDS + Class III & IV devices|
Implementation Stage 1
In the first stage of implementation of proactive public release, Health Canada aims to publish the clinical information within drug submissions for:
- new active substances (NDS-NAS), representing submissions for drugs that are not variations of previously approved medicinal ingredients in Canada, i.e. "innovative" drugs;
- supplemental new drug submissions containing confirmatory trials (SNDS-c) following the issuance of a notice of compliance with conditions as agreed to in the Letter of Undertaking; and
- submissions to switch an authorized medicinal ingredient to non-prescription status (Rx-switch for full switch and partial switch submissions).
Implementation Stage 2
In stage two, Health Canada intends on adding the proactive publication of clinical information within all new drug submissions (both NDS-NAS and those not categorized as new active substances).
Implementation Stage 3
In stage three, Health Canada intends on adding the proactive publication of clinical information within all supplemental new drug submissions (SNDS) (e.g. submissions for new indications to a marketed product), and in-scope clinical information within Class IV medical device applications.
It is anticipated that the timing of stage three will align with the adoption of the IMDRF-ToC application structure for medical device applications, to permit the efficient publication of Class III and IV clinical information.
Implementation Stage 4
In stage four, Health Canada intends on adding the proactive publication of clinical information from abbreviated new drug submissions (ANDS; i.e., generic drug), and from Class III medical device applications.
3.4 On-request Release of Clinical Information in Past Drug Submissions and Medical Device Applications
Clinical information from past drug submissions and medical device applications (which received a final regulatory decision prior to the coming into force of the regulations on March 20, 2019) may be requested through Health Canada's clinical information portal. Information in submissions and applications that received a final decision after that date but which was not yet subject to proactive publication is also available on request.
The information in the following submission and application types is available on request:
- New Drug Submissions (NDS)
- Supplemental New Drug Submissions (SNDS)
- Abbreviated New Drug Submissions (ANDS)
- Supplemental Abbreviated New Drug Submissions (SANDS)
- Extraordinary Use New Drug Submissions (EUNDS)
- Supplemental Extraordinary Use New Drug Submissions (SEUNDS)
- Class III Medical Device Application
- Class III Medical Device Application Amendment
- Class IV Medical Device Application
- Class IV Medical Device Application Amendment
A request for clinical information from past submissions should be submitted using the online request form on Health Canada's clinical information portal, as described in Section 4.3 of this guidance.
4. Procedures for Clinical Information in Drug Submissions and Medical Device Applications
The publication of clinical information under the Public Release of Clinical Information initiative proceeds through five distinct phases - initiation, submission, review, finalization, and publication.
Health Canada aims to upload a final redacted and anonymized clinical information package onto Health Canada's clinical information portal within 120 calendar days from initiation of the process. In the event that a request is received for clinical information that is not currently in an electronic format, additional time may be required for digitization of paper records.
4.1 PRCI Process Initiation Meeting
Prior to the initiation of the publication of clinical information, a sponsor may elect to attend a one-on-one process initiation meeting (PIM).
The purpose of the PIM is to allow a sponsor to consult with Health Canada on the clinical documents in scope of release under PRCI, and provide an opportunity to clarify Health Canada's requirements and process.
Sponsors new to this initiative are encouraged to request a PIM prior to starting the process. A PIM may be requested within the period of time 120 calendar days prior to the final regulatory decision, and up to 20 calendar days following the final regulatory decision.
Requests for a PIM should be submitted to email@example.com.
Requests should propose several dates and times within the eligible period of time for the PIM consultation. A request for a PIM should also be accompanied by the following information:
- An agenda or brief meeting outline;
- A list of questions, if any, to be addressed by the PRCI team during the meeting.
Health Canada will acknowledge the request and confirm the meeting date.
PIMs will be conducted via teleconference only.
4.2 Health Canada Initiation of the Publication of Clinical Information
Positive Regulatory Decisions
Publication of clinical information is initiated upon issuance of the qualifying regulatory decision on the drug submission or medical device application; initiation triggers an email notification to the manufacturer, though manufacturers may start to prepare clinical information for publication prior to receiving the Health Canada notification.
The notification email identifies the drug submission or medical device application, and lists the documents Health Canada will publicly release. Appendices A and B specify the sections of a drug submission eligible for release, based on the eCTD format. As medical device applications currently vary in structure, the sections eligible for public release will be determined by Health Canada on a case by case basis. Future guidance on medical device applications will be developed to align with transparency initiatives of other regulatory agencies and with a new internationally harmonized format that is currently under development (IMDRF ToC).
Health Canada requests that within 60 calendar days the manufacturer submit the de-identified documents with proposed redaction(s). A proposed redaction control sheet (in.CSV file format, see template in appendix E) and anonymization report (see template in appendix F) must also be submitted, as described below.
Negative Regulatory Decisions
In the event a drug submission is found to not comply with the FDR, Health Canada will initiate publication 31 calendar days after the date of the notice, unless a Letter of Intent for Reconsideration has been received from the manufacturer.
In the event the manufacturer submits a Letter of Intent for Reconsideration, Health Canada will initiate publication upon completion of the reconsideration process, as described in the guidance "Reconsideration of Final Decisions Issued for Human Drug Submissions". This is expected to require 70-140 calendar days, depending on whether the request is referred for internal or external review.
In the event a medical device application is found to not comply with the MDR and the manufacturer submits a Letter of Intent to Appeal, Health Canada will initiate publication upon issuance of a decision of the appeal process, in accordance with the guidance "Management of Applications for Medical Device Licences and Investigational Testing Authorizations".
In the case of a first-level appeal, should the manufacturer not submit the necessary information supporting the appeal, Health Canada will initiate publication 21 days after receipt of a manufacturer's Letter of Intent to Appeal to the Bureau Director. In the case of a second-level appeal, Health Canada will initiate publication upon notification to the manufacturer of the Directorate's decision on the appeal.
Manufacturers will be notified by email when Health Canada initiates publication of clinical information related to a negative decision. The notification will include the same information and procedures as in the case of positive decisions (see above).
4.3 How to Request Clinical Information from Past Drug Submissions and Medical Device Applications
Health Canada plans to publish clinical information from past drug submissions and medical device applications upon receipt of a request from the public and within the limits of its administrative capacity. Requests made for multiple submissions or applications will be processed in sequence and subject to prioritization.
Members of the public may request clinical information from past submissions and applications through Health Canada's clinical information portal with an electronic request form identifying the product name, the name of the manufacturer, the related indication, the information being requested (e.g. clinical study report, clinical overview, clinical summary), the reason for the request, and the requester's contact information.
Where possible, the requester should provide Health Canada with the submission/application control number. This additional information is available within Health Canada's Summary Basis of Decision and Regulatory Decision Summary documents associated with the drug submission or medical device application.
Health Canada will confirm receipt of requests by direct notification to individual requesters. It will also regularly update a list of requests on its web portal.
Prioritization of Requests
In the event requests for information exceed Health Canada's administrative capacity, Health Canada will process requests for clinical information in priority sequence. Health Canada's prioritization of requests will consider metrics that identify products and information with high health system impact. These considerations include prioritizing drugs and medical devices that are subject to ongoing queries by health system organizations, products that are abundantly used, and products that have been demonstrated to be of high public interest.
Where there are multiple requests for submissions from a single manufacturer they may be sequenced to avoid excessive requirements to review information prior to release. Health Canada will notify requesters when it initiates processing of their request, and will regularly update the web portal to indicate which requests are currently being processed.
4.4 Submission of Annotated Documents with Proposed CBI Redaction(s) and Anonymization
Health Canada has described limited and specific circumstances, prescribed in regulations, where information found within the clinical component of a drug submission or medical device application may have ongoing commercial value following the final regulatory decision. The specific categories of information in drug submissions that Health Canada will consider for redaction (with sufficient justification) are described in Section 5 of this guidance document.
Future guidance will specify these categories for medical device applications based on the IMDRF TOC standardized format, which is currently under development. In the interim, medical device manufacturers should refer to Section 5 for guidance in proposing redactions consistent with the exceptions specified in the Medical Device Regulations section 43.12(2).
The justification of certain redactions may require the manufacturer to draw on information within their internal corporate plans (e.g. future development of new indications based on secondary outcome data). Consequently, Health Canada requests that the manufacturer submit an annotated version of all clinical information in scope of publication with any and all proposed redactions highlighted. Any text the manufacturer proposes to redact must remain readable, and all proposed redactions should be accompanied by specific and detailed justification recorded using the "Proposed Redaction Control Sheet" in.CSV format. Please refer to Appendix E for the control sheet template.
The annotated documents in drug submissions and medical device applications must also be anonymized in accordance with the process outlined in Section 5 of this Guidance document. The process of data anonymization should be detailed in a separate Anonymization report (see Appendix F for the Anonymization Report Template).
Once the manufacturer has prepared the above documents, Health Canada requests that the documents be transmitted through the Common Electronic Submissions Gateway (CESG). Documents submitted via the CESG must follow the defined naming convention outlined in Appendix D.
Health Canada may return to the manufacturer on one additional occasion to seek additional justification. The final decision on what clinical information is publicly released rests with Health Canada.
Relying on Previously Redacted Information
With appropriate certification, the manufacturer may submit to Health Canada final redacted documents of a drug submission that were previously accepted by the European Medicines Agency (EMA). Upon receipt of a Health Canada notification to prepare annotated documents for public release, in the case that this clinical information was previously released by the European Medicines Agency policy on publication of clinical data for medicinal products for human use (EMA Policy 0070), the manufacturer can choose this alternative pathway.
Manufacturers must submit final redacted documents using the CESG, as above.
Health Canada requests that manufacturers submit their certification using the template certification form found in Appendix G. Submission of this form attests that the clinical information in scope of Health Canada's Public Release of Clinical Information is identical to the clinical information published under EMA Policy 0070.
In circumstances where only a component of the information requested for release by Health Canada was previously redacted for the EMA, manufacturers may resubmit the same information with certification, and only redact the outstanding components for Health Canada.
4.5 Health Canada Review of Annotated Documents
Health Canada will review the manufacturer's justifications for each proposed redaction within the annotated documents. All proposed redactions will be assessed against the exceptions permitted under the regulations (see Section 5). Following review, proposed redactions will be accepted or rejected prior to finalization of the clinical information for public release.
Proposed redactions may be rejected for the following reasons:
- When the manufacturer fails to adequately demonstrate that the information was not used to support the conditions of use or purpose for the drug or medical device, as set out in the submission or application;
- When the manufacturer fails to adequately justify that the proposed information describes a test, method, or assay that is used exclusively by the manufacturer;
- When the manufacturer fails to demonstrate that the proposed information is out of scope of the regulations;
- When the proposed redaction pertains to information already in the public domain.
Health Canada will inform the manufacturer of any proposed redactions that the Department rejects. Manufacturers will be given one additional opportunity to further justify a redaction following Health Canada's review.
As outlined in Section 6, Health Canada requests the manufacturer to anonymize the clinical information using a risk-based anonymization process. Health Canada's review will reject the transformation of any data that is not accompanied by adequate justification. Health Canada retains final decision on what information is publicly released.
4.6 Finalization of Documents
Following Health Canada's review, the manufacturer must submit a final version of the documents, according to Health Canada instructions:
- All accepted proposed redactions must be converted into non-readable text; redacted text should not be machine-readable or searchable. Redactions must be clearly visible (typically using an opaque box) and should be labeled to distinguish between CBI and personal information. Alternatively, EMA specifications on redacted text are permissible.
- All proposed data transformations for the purposes of anonymization should be finalized; a revised Anonymization report which excludes any personal information will be prepared to accompany the final anonymized clinical documents (see Section 5 for more information on the requirements for the Anonymization report).
- The final documents should be named in accordance with the naming conventions identified in Appendix D, and submitted to Health Canada via the CESG.
4.7 Publication of Final Documents
5. Requirements for the Redaction of Confidential Business Information
Two categories of clinical information will remain subject to the FDA definition of CBI. With valid justification by the manufacturer, Health Canada will protect the following from public release:
- Clinical information that was not used by the manufacturer in the drug submission or supplement, or medical device application to support the proposed conditions of use or the purpose for which the drug or medical device is recommended; or
- Clinical information that describes tests, methods or assays used exclusively by the manufacturer.
1) As per C.08.009.2(2)(a) of the FDR, clinical information submitted by the manufacturer but that did not support the proposed conditions of use for the drug, or the purpose for which the drug is recommended, does not cease to be confidential business information following Health Canada's final regulatory decision.
Similarly, as per section 43.12(2)(a) of the MDR, clinical information submitted by the manufacturer that did not support the features of the device that permit it to be used for the medical conditions, purpose and uses for which it is manufactured, sold or represented, does not cease to be confidential business information following Health Canada's regulatory decision.
As an example, a manufacturer may be using secondary or exploratory outcome measure data described in the clinical information to support future trials to gain approval for a new indication of use. Release of this information could provide a competitor with insight about the drug's future uses.
Clinical study reports, overviews, and summaries may contain data and discussion about secondary or exploratory end points that do not support the conditions of use or purpose of the product for which the submission or application seeks market authorization. In the rare instance where this information may form a component of an on-going development program for new claims, given adequate justification Health Canada will protect this information from public release.
2) As per C.08.009.2(2)(b) of the FDR and section 43.12(2)(b) of the MDR, clinical information in respect of tests, methods or assays that are used exclusively by the manufacturer do not cease to be CBI following Health Canada's final regulatory decision.
As an example, a manufacturer may develop novel modifications to a bioassay that is then used to collect clinical data. In certain instances, such modifications may rely on considerable effort and investment by the manufacturer and may be used for other ongoing studies or other routine use. Such modifications may be considered to be exclusively used by the manufacturer.
Clinical study reports, overviews, and summaries may include details, specifications, and validation information on assays and/or test methods developed exclusively by the submission sponsor or another third party and used exclusively by the submission sponsor. In the event that these methodological details have not been published in the public domain, and with adequate justification, Health Canada will protect this information from public release.
Regardless of its location in a drug submission, chemistry, manufacturing, and other non-clinical information will remain subject to the FDA definition of confidential business information.
6. Anonymization of Personal Information
6.1 Principles of Protecting Personal Information
The federal Privacy Act defines "personal information" as information about an identifiable individual that is recorded in any form; specific and non-exhaustive examples are then listed. Clinical information contains information that falls under this definition of personal information.
The Federal Court has adopted the "serious possibility" test to determine when information is about an identifiable individual (Gordon v. Canada (Health), 2008 FC 258). Clinical information must be adequately anonymized prior to public disclosure to avoid the serious possibility of identifying individual clinical trial patients; this requires the application of an objective, systematic, and documented process of anonymization.
In order to maximize the release of analytically-valuable information and to retain the most utility of the published clinical information, the anonymization of clinical information should be guided by the following principles:
- 1 - All transformation of data should be conducted for the sole purpose of preventing the disclosure of personal information;
- 2 - All data transformations should be accompanied by robust justification, and be applied to limited variables that risk re-identification, not to broad sections of clinical information; and
- 3 - Data transformation should favour methods that retain analytical value, e.g. generalization, randomization and offsetting, as opposed to redaction.
6.2 Anonymization Process
Many anonymization frameworks currently exist and are publicly available. Health Canada encourages a 3-step process adapted from the 2016 Information and Privacy Commissioner of Ontario De-identification Guidelines. The process of anonymization should broadly follow the following three steps:
- Step 1: Identify and classify the variables
- Step 2: Measure the re-identification risk
- Step 3: Anonymize the data
By adopting an anonymization process that follows these steps, the risk of disclosing personal information can be reliably reduced. An anonymization approach which includes objective risk measurement and appropriate reference population selection provides further benefits by maximizing data utility while inherently adjusting for variable sensitivities of certain study populations.
Step 1: Identify and Classify the Variables
Directly-identifying and indirectly-identifying variables must be classified prior to processing the clinical information for anonymization.
Directly-identifying variables are commonly described as information that meets the test of being:
- A - Replicable, in the sense that the variable is unlikely to frequently vary over time;
- B - Distinguishable, in the sense that individual patients may have distinct recognizable values; and
- C - Knowable, in the sense that someone knows the variable associated with a certain individual.
Directly-identifying variables can be either uniquely identifying (e.g. a patient's social insurance number), or not uniquely identifying (e.g. patient name). Some variables classified as directly-identifying may not be necessary for the purposes of understanding the clinical information (e.g. patient initials), while others may be necessary (e.g. subject identification numbers). The disclosure of directly-identifying variables presents a serious possibility of re-identifying an individual.
Indirectly-identifying variables are other identifying variables that fall within the definition of 'personal information' within Canada's Privacy Act. In order for an indirectly-identifying variable to require anonymization, its disclosure must present a serious possibility of re-identifying an individual when combined with other available information (e.g. demographic data). Indirectly-identifying variables may be necessary for the purpose of understanding the clinical information, and therefore their anonymization must be carefully justified, in line with the guiding anonymization principle number 2.
Step 2: Measure the Re-identification Risk
Once the variables have been classified, the data risk needs to be measured. This risk measurement provides justification for any data transformation that may follow. Variables which do not present a serious possibility of re-identifying an individual, alone or in combination with other information, are not considered personal information and should not be transformed.
The overall risk of re-identification associated with the disclosure of clinical information is the product of the risk inherent to the data and the risk associated with the context of the release. For the public release of clinical information (to the general public), the calculation of risk of re-identification needs to reflect this environment; in a public release environment, the context risk is unreducible, so the overall risk of re-identification is equivalent to the risk inherent to the data (as opposed to the release of information to a small and select group of individuals, which would constitute a lower context risk, and therefore a lower risk of re-identification).
Measurement of Re-identification Risk for Directly-identifying Variables
Directly-identifying variables possess a serious risk of identifying a trial participant, and should be assumed to carry a 100% risk of re-identification (risk=1.0); invariably these variables require anonymization in order to sufficiently reduce the risk of trial participant re-identification.
Measurement of Re-identification Risk for Indirectly-identifying Variables
The risk of re-identification for indirectly-identifying variables associated with a patient needs to be calculated on a patient level. One straightforward method of calculating the risk of re-identification for indirectly-identifying variables is to measure the cell size.
Cell size is defined as the number of patients with the same indirectly-identifying variable values. Adopting a risk threshold of risk=0.09 equates to a target cell size of 11 patients. Once indirectly-identifying variables in need of anonymization are identified, the data for the corresponding patients should be anonymized in order to achieve a cell size of 11.
Reference Population for Indirectly-identifying Variables
The selection of the appropriate reference population determines the total patient group size and the amount of anonymization (i.e. data transformation) that is necessary to reduce the risk of patient re-identification. The reference population can be informed from patients in the single trial in question (smallest population), all patients in similar trials by a specific study sponsor, all patients in similar trials (e.g.. by disease or therapeutic intervention category), or all patients in a geographic area (largest population).
When the appropriate reference population is one other than the single trial in question, an extrapolation of the trial population can be applied to achieve an estimate of the population size. In keeping with the first and second guiding principle, risk of re-identification should be informed not only by the number of individuals in a single study, but also by the number that reflects real-world risk.
Health Canada encourages adopting a 9% re-identification risk threshold (risk=0.09). This aligns with the risk threshold cited in the EMA Policy 0070 External Guidance and is in agreement with other public data disclosure risk thresholds. While a qualitative approach to risk measurement can be taken, a quantitative approach has the advantage of being based on empirical measurement and consequently is more precise, less subjective, and typically retains more data utility. In the event a qualitative approach to re-identification risk measurement is adopted, following anonymization the clinical information should no longer pose a serious possibility of identifying a person.
Step 3: Anonymize the Data
The methodology used to anonymize clinical information can have a detrimental effect on its utility. Data that is preserved retains the greatest utility. Consequently, it is advisable to not transform (anonymize) variables that do not contribute to the risk of re-identification, and to adopt methods that have the lowest impact on data utility.
Anonymization of Directly-identifying Variables
Directly-identifying variables may be anonymized through the process of redaction, pseudonymization, or randomization. Directly-identifying variables may be redacted if the removal of the variable will not be detrimental to the understanding of the clinical information. When a directly-identifying variable is critical to the understanding of the clinical information, other anonymization methods should be selected. For example, in the case of subject identification numbers, the use of pseudonymization ensures that the capacity to link clinical trial participant data throughout the study records is preserved.
Examples of directly-identifying variables that may be redacted include:
- job titles/positions
- fax numbers
- email addresses
- health plan beneficiary numbers
- batch/serial numbers
- telephone numbers
Anonymization of Indirectly-identifying Variables
Health Canada encourages the generalization of indirectly-identifying variables. These variables may include: city, state/province, zip/postal code, demographic data (race, gender, etc.), medical history, serious adverse events, dates, height, weight, and BMI.
In certain circumstances, following generalization, the variables should be re-synthesized to avoid the appearance of anonymization. The subsequent re-synthesis is expected to achieve further risk reduction due to inability to identify leaked identifiers.
Documenting the Anonymization Process and Governance
The process of anonymization should be thoroughly documented to provide the necessary audit trail. Health Canada requests that the manufacturers submit a completed Anonymization Report (template provided in Appendix F) with the submission of all anonymized clinical information.

Appendix C: Process Flow Chart
Appendix D: Document Naming Convention for Submissions Through the CESG
Anonymized clinical information with proposed redactions, the accompanying redaction control sheets, and anonymization reports should be submitted via the CESG using node extension titles that are the same as the parent submission.
The file format in which documents must be submitted is PDF format.
The file naming convention for all documents with proposed redactions should follow the original file naming convention used in the original submission with the addition of "-pr" as a suffix. It is assumed that the original file naming convention was chosen in accordance with Health Canada's guidance document: Preparation of Drug Regulatory Activities in the Electronic Common Technical Document Format.
"-pr" = proposed redaction
E.g. clinical-overview-pr.pdf, summary-clin-safety-pr.pdf, study-XXXXXX-pr.pdf
Once redactions are finalized, Health Canada will apply the "-red" suffix, to the final anonymized documents prior to publication.
"-red" = final redaction
E.g. clinical-overview-red.pdf, summary-clin-safety-red.pdf, study-XXXXXX-red.pdf
