Contact details for argenx are set out in section 10

3. What data we collect and how we use it

3.1. Data collected for registration

You may download the app from Android or iOS app stores. When you install the app, you will be asked to register with us and provide us with information to enable us to assess your eligibility for participation in the Study.

Once you have completed this information, if you are eligible to participate in the Study, you will be able to create a username and password for the app. We will also assign you with a respondent ID, which we will use for administrative purposes. If you are not eligible to participate, we will let you know, and will remove your details from our systems within a reasonable period – see section 7

3.2. Data collected during the Study

You will be asked to enter personal information and data into the app as part of the Study.

As such, the data you enter into the app will be transferred into a database, de-identified and aggregated by Vitaccess before it is shared with authorized recipients. This means that your name and other personally identifiable information will be removed from the data before it is shared. Authorized recipients of the data include argenx, the Study Investigator, Veritas IRB (except Alberta and Newfoundland and Labrador), and other qualified parties using the data for research purposes. See section 4.

Vitaccess will have a key which allows us to re-identify you if needed, but this key will only be used in exceptional circumstances, for example if a clinician has identified a health risk for a particular patient arising from the Study.

The data collected during the Study will be used by argenx and authorized recipients to better understand current treatments, identify new topics for research, improve MG research design, and ultimately, improve patient care. argenx will use the data you provide for research purposes and may also publish aggregated data from this Study and present it at scientific meetings.

3.3. Sharing your information with other participants and viewing other participants’ data

The app may provide you with features that allow you to share some of your personal data with other participants. If you consent to display or share disease-related data with other study participants or users of the app, we ask that you regularly review and set your sharing options. If you view or receive information about other participants or users of the app, please respect the privacy of such individuals and the confidentiality and sensitivity of their data.

3.4. Other uses of the data you share

Your personal data is used for Study purposes but may also be used by us on behalf of argenx:

Vitaccess may, in limited circumstances, use your personal data for our own business purposes. These purposes include protection of our software and intellectual property (and other rights and responsibilities in relation to the app and our technology), administering our technology and our relationship with argenx, and maintaining appropriate records relating to the same.

3.5. Special categories of data: health data

The activities described previously involve collection and use of special categories of data (also known as “sensitive data”), including the following:

4. Sharing your data with other parties

In addition to argenx and Vitaccess, these additional parties will have access to your de-identified data as described below:

4.1. Scientific Advisory Board

The Scientific Advisory Board is an advisory body established to protect participants’ interests and provide advice on research-related requests to access data in the database. The Scientific Advisory Board will generally only access and use the data, which is de-identified and aggregated by Vitaccess, from the database. If the Scientific Advisory Board needs to contact you personally, it would obtain independent ethics approval to do so.

4.2. Veritas IRB and other accrediting agencies

Veritas IRB and Newfoundland and Labrador Health Research Ethics Board are the bodies which have approved the Study for the purposes of ethics requirements and may review the study activities to confirm it is being conducted appropriately. As part of this review, Veritas IRB may access the database. In general, Veritas IRB will only access and use de-identified and aggregated data.

You may contact Veritas via this contact form or Newfoundland and Labrador Health Research Ethics Board at:, if you would like to speak with someone unrelated to the Study, have questions, concerns, or complaints regarding the study, or have questions about your rights as a research participant. If you do so, Veritas IRB or Newfoundland and Labrador Health Research Ethics Board will use your personal data to assist you with your query.

4.3. Study Investigator

The Study Investigator is Dr Mark Larkin, the CEO of Vitaccess. His role is to ensure the Study is conducted appropriately and completed within the agreed period. The scope of data shared with the Study Investigator will be determined by argenx – please contact argenx for further information. The Study Investigator will generally only access and use de-identified data.

4.4. Users of the research portal, publications and presentations

Aggregated and de-identified information arising from the Study will be used to help researchers understand what treatments works for MG and what does not, which will improve the treatments that are offered to patients in the future. Access to the research portal by third-party researchers will be overseen by the Scientific Advisory Board.

These details may also be presented at conferences and published in peer-reviewed journals by argenx – please contact argenx for further information about this.

4.5. Your clinical team

We do not share your personal data with your physician or clinical team, though you may choose to share your personal data with them within the app.

4.6. Our technology service providers

Our technology service providers may handle your data. They act as sub-processors on behalf of argenx (but appointed by us), meaning that argenx remains primarily responsible for how they use your data, and we pass on our responsibilities as a processor to such providers within our agreements and arrangements with them. Our providers (as of the date of this notice) provide platforms on which we store your data, and assist us and argenx to analyse and pseudonymize your data.

4.7. Other parties

We may also share your data, where required, with legal authorities or regulatory bodies. For example, other accredited agencies investigating matters related to the appropriate conduct of this Study.

argenx is responsible for determining any additional disclosures of your personal data, outside the scope of Vitaccess's involvement. You should contact argenx directly for more information about this – see contact details in section 10.

5. Consents and legal basis for use of your data

We need your consent for the collection, use, and disclosure of your information. If you chose not to consent, which is your right, to your data being used for any specific activity (or withdraw any consent previously given) you may not be able to participate with that activity.

We will collect, use, and disclose your data as described in this Privacy Notice. We also may (on behalf of argenx or directly, where required) collect, use or disclose personal data as is necessary to comply with a legal obligation, such as where law enforcement authorities require us or argenx to do so, or to address rights of individuals under data protection laws.

6. International data transfers

As the Study is an international project, your data may be transferred to a different country to that in which you are based. This may include:

In all cases, where data is transferred to providers based outside the UK or the European Union, we will check that appropriate safeguards are in place to protect your data to a similar standard as under UK and Belgian law.

7. How long do we retain your information?

We will retain your personal data for as long as required for the purpose of the Study.

If you are discontinued or withdraw from the Study after we have collected information about you, no new study data about you will be collected by Vitaccess. However, all your data that have been collected to date will remain within the study database. If you prefer that your data be removed from the study database, Vitaccess can be contacted using the contact details in section 10. Note that your information may still included in aggregated and de-identified datasets which have already been collated and used for research purposes.

We may also continue to maintain records relating to you (such as your name, contact details, communications with you, and information about how you used the app):

8. Security of your data

You will be able to select a password to access your MyRealWorld MG account. We recommend you use a strong password of at least twelve characters, including one upper and one lower case letter, one special character and one number.

You are also advised to enable a password-protected screen lock from your device's Settings menu.

Your data entries within the app are encrypted before being sent to our systems and information within the study database is de-identified.

If you would like any further information about our information security measures, please contact us or argenx using the contact details at section 10.
