While in some instances we may collect personal data about children with the consent of a parent or guardian, such as clinical activities or for patient support programs, we do not otherwise knowingly solicit data from, or market to, children. If a parent or guardian becomes aware that his or her child has provided us with personal data, he or she should contact us as described in Section A of this Notice (“How to Contact Us”). We will take reasonable steps to delete such data from our database within a reasonable time.


This Notice does not address, and Axcella is not responsible for the terms of use, information or privacy practices of any other websites or online services not owned or operated by Axcella, including any such sites or services to which our Axcella website links.  The inclusion of a link on the Axcella website does not imply our endorsement of the linked site or service.


Axcella may update this Notice from time to time.  Please check this Notice periodically for changes.  If we make any changes, the updated Notice will be posted with a revised effective date.  We encourage you to periodically review this page for the latest information on our privacy practices.


European Union Regulation 2016/679 of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (the “General Data Protection Regulation” or “GDPR”) requires Axcella as the data controller to provide additional and different information about its data processing practices to data subjects in the European Economic Area (“EEA”). If you are a data subject within the EEA, this Supplemental European Privacy Notice applies to you in addition to the provisions above.


We will only use your personal data when the law allows us to so. Most commonly, we will use your personal data in the following circumstances:

  • We need to perform the contract we are about to enter into or have entered into with you.

  • It is necessary for our legitimate interests (or those of a third party) and your interests and fundamental rights do not override those interests.

  • We need to comply with a legal or regulatory obligation.

  • It is necessary for scientific research purposes.

    We may also use your personal data in the following situations, which are likely to be rare:

  • We need to protect your vital interests (or someone else’s).

  • It is needed in the public interest or for official purposes.

We may also rely on consent as a legal basis for processing your personal data in certain circumstances, like sending direct marketing communications to you via email or text message. You have the right to withdraw consent to marketing at any time by contacting us.

We have set out below, in a table format, a description of many of the ways we plan to use your personal data, and which of the legal bases we rely on to do so. We have also identified what our legitimate interests are where appropriate.

Note that we may process your personal data for more than one lawful ground depending on the specific purpose for which we are using your data. Please contact us if you need additional details about the specific legal ground we are relying on to process your personal data.



We undertake clinical studies within the EEA and we will use information from subjects’ medical records and other health data in order to strive to improve healthcare. If a person is determined to be eligible for a clinical study and decides to participate, important information (contained in what is known as an informed consent form) is reviewed with each patient by a study professional at the study site. Each patient must read and sign this informed consent form, which describes possible health risks and possible benefits of participating in the study, as well as what personal data will be collected in the study and who is able to use or disclose any personal information, before enrolling. Anyone can decline to participate in a study at any time.

As a pharmaceutical organisation we have a legitimate interest in using information relating to your health for research studies when you agree to take part in a research study. Our exception to the general principle not to process special categories of data is that processing is necessary for scientific research purposes. This means that we will use your health data that we collect during a research study when we act as the data controller for such studies in the ways needed to conduct and analyse the research study. Your rights to access, change or move your information are limited, as we need to manage your information in specific ways in order for the research to be reliable and accurate. If you withdraw from the study, we will keep the information about you that we have already obtained. To safeguard your rights, we will use the minimum personal data necessary to achieve our purpose(s).


We will only use your personal data for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose.

If we need to use your personal data for an unrelated purpose, we will notify you and we will explain the new legal basis.

Please note that we may process your personal data without your knowledge or consent, in compliance with the above rules, where this is required or permitted by law.


We are based outside the European Economic Area, so the processing of your personal data may involve a transfer of data outside the EEA. Information on how to contact the appropriate Axcella resource for privacy inquiries related to international data transfers can be found in Section A of this Notice (“How to Contact Us”).

Whenever we transfer your personal data out of the EEA, we ensure a similar degree of protection is afforded to it by ensuring at least one of the following safeguards is implemented:

  • We will only transfer your personal data to countries that have been deemed to provide an adequate level of protection for personal data by the European Commission.

  • Where we use certain service providers, we may use specific contracts approved by the European Commission which give personal data the same protection it has in Europe.

  • Regarding transfers to the US, we are required to incorporate the model clauses in agreements for transfer provided by the European Commission in order to provide similar protection to personal data shared within Europe.


We will only retain your personal data for as long as necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, accounting, or reporting requirements.

To determine the appropriate retention period for personal data, we consider the amount, nature, and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means, and the applicable legal requirements.

In some circumstances we may anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes in which case we may use this information indefinitely without further notice to you.


Under certain circumstances, visitors from within the EEA have the following data protection rights in accordance with applicable law:

  • access to your personal data.

  • correction of your personal data.

  • erasure of your personal data.

  • object to processing of your personal data.

  • restrict of processing your personal data.

  • transfer of your personal data.

  • withdraw consent to any consent that you have previously given.

If you wish to exercise any of the rights set out above, please contact us using the information contained in Section A. You can also contact the Supervisory Authority in the country of your residence within the EU at this link for advice or to make a complaint. Please be aware that your rights in relation to clinical research data may be limited.

You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee or refuse to comply with your request if it is clearly unfounded, repetitive or excessive.

We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.

We try to respond to all legitimate requests within one month. Occasionally it may take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.
