GDPR Data Protection Notice

Trevi Therapeutics (the “Company,” “we,” or “us”) is committed to protecting personal data it collects and processes. This Notice applies in the context of Company’s personal data processing activities as a data controller only to the extent the activities are subject to data protection requirements in the European Union, European Economic Area (EEA), Switzerland or the United Kingdom (collectively, “EU”). We want to be sure you understand our privacy practices when we are engaged in processing personal data affecting individuals in the EU. This Notice explains the types of personal data we collect, why we collect it, how we use and share it, and the rights of data subjects. If there is any conflict between this Notice and our U.S. Website Privacy Notice, this Notice will apply instead of the U.S. Website Privacy Notice with respect to our processing activities based in the EU.

If we collect your personal data in connection with your participation in or operation of one of our clinical trials in the EU, we will provide you with a separate information notice (which may be a part of a consent form) at the time we collect your personal data for those purposes. The notice will describe how your personal data is processed and the responsibilities of the respective controllers in the context of the clinical trial.

We may revise this Notice from time to time. If we decide to change this Notice, we will post the revised Notice on our website (“Website”). If changes materially affect your rights under this Notice, we may provide a more prominent notice on the Website. In certain cases, we may also provide email notification of the revised Notice and either seek your consent or give you the right to opt out of our use of your personal data in accordance with the revised Notice, if required. However, because we may make changes at any time, we suggest that you periodically consult this Notice. Please note that our data protection practices will be based on the Notice in effect at the time the personal data is processed.

Personal data will be transferred to the U.S. based on SCCs taking into account the circumstances surrounding the transfer and an assessment of supplementary measures that demonstrate that the U.S. law does not impinge on the promise of adequate data protection set forth in the SCCs.
