Privacy Notice for Clinical Trials – Non-EU Participants

Please note, this privacy notice has also been translated into the following languages:

Xenon Pharmaceuticals Inc., and its wholly owned subsidiaries (together referred to as “Xenon”) are committed to protecting the Personal Information we process for the purpose of conducting clinical trials. This Privacy Notice sets forth the privacy principles and procedures and the technical security measures we follow to keep Clinical Trial Data private and secure.

Xenon is subject to applicable privacy and data protection legislation where our clinical trials are conducted.

This privacy notice is for data subjects participating in trials outside of the European Union (EU), Switzerland and the UK. If you are participating in a clinical trial in the EU, Switzerland or in the UK, please refer to the Privacy Notice for data subjects in the EU: PRIVACY NOTICE FOR CLINICAL TRIALS – EU PARTICIPANTS.

Xenon and Clinical Trial Data

Xenon does not collect Clinical Trial Data directly from individuals during the course of our clinical trials (except in the context of monitoring the study to ensure quality standards are met). Instead, we receive Pseudonymized Data from the clinical sites via Contract Research Organizations (“CRO”) and service providers (“third parties”) that we engage to carry out the study.   

Investigators enrolling Clinical Trial Participants in the study will provide participants with information about the trial, how Personal Information will be managed and protected, and a link to this Privacy Notice at the time of enrollment.  

If you are participating in a clinical trial and would like more information about the specific trial in which you are enrolled, the Informed Consent Form that you completed for the trial or the Personal Information you have provided for the trial, please contact the physician or the hospital that enrolled you in the trial. Xenon will not be in a position to identify you personally from the trial data we hold, given we only collect Pseudonymized Data. 

Privacy Officer Information

Xenon has designated a Privacy Officer responsible for overseeing our privacy management program and compliance with privacy legislation.

Privacy Officer

This Privacy Notice applies to Personal Information that is received and processed by Xenon in any format, including electronic and paper for the purposes of conducting a clinical trial in North America. More information about the third party organizations we engage to conduct trials can be found below.


“Anonymous Data” is information which does not relate to an identified or identifiable natural person or personal data rendered anonymous in such a manner that the data subject is not or no longer identifiable. Privacy legislation does not concern the processing of Anonymous Data. 

“Clinical Trial Data” is the data collected and processed by Xenon for clinical trial purposes. It includes Pseudonymized Data received from third parties as well as new data generated by Xenon and third parties based on data collected for the clinical trial. These new data may not relate to an identified or identifiable natural person.  

“Clinical Trial Participant” means an individual participating in a clinical trial and providing Personal Information to clinical sites and other third parties Xenon has contracted with to conduct the study.  

“Personal Information” means any information about an identifiable individual and includes Personal Health Information. 

“Personal Health Information” means, with respect to an individual, whether living or dead: 

  1. Information concerning the physical or mental health of the individual; 
  1. Information concerning any health service provided to the individual; 
  1. Information concerning the donation by the individual of any body part or any bodily substance of the individual or information derived from the testing or examination of a body part or bodily substance of the individual; 
  1. Information that is collected in the course of providing health services to the individual; or  
  1. Information that is collected incidentally to the provision of health services to the individual. 

“Pseudonymized Data” means Personal Information and Personal Health Information that has been de-identified. This means it can no longer be attributed to a specific individual without the use of additional information. Personal Information will be considered pseudonymized provided that such additional information is kept separately and is subject to technical and organizational measures to ensure that the Personal Information is not attributed to an individual. Xenon will protect Pseudonymized Data with the same care and high standards as Personal Information. 

“Processing” means any operations or set of operations performed on Personal Information. It includes the collection, use and disclosure of Personal Information as defined in Canada’s Personal Information Protection and Electronic Documents Act (“PIPEDA”), or applicable data protection and data privacy laws in British Columbia, Alberta and Quebec. 

Collection of Personal Information

When individuals become Clinical Trial Participants, Personal Information will be collected and processed for the purpose of scientific research into the effects of medical treatment.  


Xenon processes Clinical Trial Data mainly based on your consent to collect and process your Personal Information. The hospital or physician enrolling you in the trial will obtain your consent prior to the collection of your data using an Informed Consent Form. Exceptionally another legal ground may be applicable for the collection and processing of your Personal Information, as reflected in the corresponding informed consent forms. 

Types of Information Processed

Xenon will collect and use the following data which will be pseudonymized using a unique subject identification number: 

  • Location data – country, investigative site 
  • Personal details – year of birth, age in years, sex 
  • Physical details – height, weight, Body Mass Index (BMI)
  • Psychological details – quality of life rating 
  • Health information
    • Childbearing status 
    • Physical health data 
    • Mental health data
    • Genetic data related to genetic research
  • Data revealing racial or ethnic origin 

Use and Disclosure

Xenon will use Pseudonymized Data for the purposes of conducting a clinical trial. We contract with a Contract Research Organization (CRO) to run a trial based on the protocols, or “instructions”, we have developed and with other vendors as applicable (e.g., laboratories etc.). The CRO selects Investigators and study sites, processes Clinical Trial Data based on the protocol, and monitors the trial activities. CROs, partners and service providers (“third parties”) engaged by Xenon for the purposes of conducting a clinical trial are required by law and contractual undertakings to: 

  • Keep your Personal Information confidential and secure; and  
  • To use and disclose it for purposes that a reasonable person would consider appropriate in the circumstances, in compliance with all applicable legislation.  

Categories of third parties that Xenon engages for clinical trials include: 

  • Wholly owned subsidiaries of Xenon  
  • Contract Research Organizations and other third-party vendors 
  • Statistical Research Analysts  
  • Clinical advisors 
  • Technical providers for hosting and software services 

The list of third parties that Xenon engages for a specific trial is available upon request.  

Location of Clinical Trial Data

Xenon Pharmaceuticals Inc. is located in Canada. Clinical Trial Data is processed in Canada, the United States and other international jurisdictions based on the appropriate legal mechanism (e.g., your consent).  


Xenon will retain Clinical Trial Data and will instruct third parties to retain Personal Information or Clinical Trial Data, depending on their role in the study, subject to applicable legislation.  

In Canada the retention period for clinical trial data is 25 years under Canadian Food and Drug Regulations.  

Individual Access and Accuracy

Where Clinical Trial Participants have a right to access, correct or update Personal Information, Xenon will provide support to exercise those rights. Xenon may not be able to comply with a direct request where Xenon is not in a position to identify you. This would occur where Xenon has received Pseudonymized Data or where Personal information has been destroyed, erased or made anonymous in accordance with our record retention obligations and practices. You can at any time reach out to your study doctor who will know how to help you. 

Your rights related to the trial, including the right to withdraw consent, as applicable, are described in the clinical trial Informed Consent Form.  

Please contact the physician or hospital that enrolled you in the clinical trial if you would like to exercise your rights related to your Personal Information collected for clinical trial purposes. 

Security Measures

We have taken appropriate technical and organizational security measures to protect Clinical Trial Data against unintentional or unlawful destruction, loss, alteration, unauthorized disclosure, unauthorized access, and any other unlawful or unauthorized forms of processing under applicable law.  

Such measures include in particular, ensuring confidentiality, integrity and availability of data by controlling physical access to the data, as well as the relevant access, input, disclosure, security of availability and its separation. In addition, we take into account the protection of Clinical Trial Data when developing or selecting the hardware, software and procedures in line with the principle of data protection through technology and privacy by design. 

Children Personal Information

Some of Xenon’s clinical trials involve participants that are children. Xenon will only process a child’s personal data with parental consent, or the consent of a legal representative, and in accordance with the laws where the clinical trial is being conducted.
