Additionally, we provide personal information to third parties including our vendors, partners and service providers (e.g., cloud service providers) who perform services on our behalf. These providers have limited access to your personal information only to the extent necessary to perform these support tasks on our behalf and subject to the same confidentiality and security safeguards as those applied by Centessa.

In certain situations, we may be required to disclose personal information in response to lawful requests by public authorities, including to meet national security or law enforcement requirements.

We are responsible and remain liable for the processing of personal information we receive, including where this involves an International Transfer of personal information as described further below.

8.     Transfer of Personal Information Outside the EEA

Where you are located within the European Economic Area (“EEA”), the personal information that we collect from you may be transferred to, and stored at, a destination outside the EEA for the purposes described above. Due to the global nature of our activities, your personal information may be disclosed to members of our group outside the EEA, including in particular in the USA. It may also be processed by staff operating outside the EEA who work for us, or for one of our suppliers who act on our behalf.

Where we transfer such personal information, we will ensure appropriate legal safeguards, such as the European Commission approved standard contractual clauses, and any additional safeguards where required, are in place to protect the privacy and integrity of such personal information.

If you would like more information concerning such safeguards, please contact us via

9.     Information Security

We have put in place appropriate security measures to prevent your personal information from being accidentally lost, used or accessed in an unauthorised way, altered or disclosed. In addition, we limit access to your personal information to those employees, agents, contractors and other third parties who have a business need-to-know. Where applicable, they will only process your personal information on our instructions, and they are subject to a duty of confidentiality.

10.  Your Rights in Connection with Personal Information

You have a number of rights afforded to you under information protection laws that relate to the personal information processed by us, as follows:

  • request access to your personal information (commonly known as a “information subject access request”). This enables you to receive a copy of the personal information we hold about you and to check that we are lawfully processing it.
  • request correction of the personal information that we hold about you. This enables you to have any incomplete or inaccurate information we hold about you corrected.
  • request erasure of your personal information. This enables you to – in certain circumstances – ask us to delete or remove personal information. You may also have the right to ask us to delete or remove your personal information where you have exercised your right to object to processing (see below).  There may be instances where we cannot delete your information due to the nature of publication or where we have a legal obligation to retain.  If this is the case, we will respond to keep you informed.
  • object to processing of your personal information where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which makes you want to object to processing on this ground. Please be advised that there may be restrictions to this right, but we will keep you informed if this is the case.
  • request the restriction of processing of your personal information. This enables you to ask us to suspend the processing of personal information about you, for example if you want us to establish its accuracy or the reason for processing it. Again, in certain circumstances, it may not be possible to restrict processing where that information has been published publicly.  If this is the case, we will respond to keep you informed.
  • request the transfer of your personal information to another party. This is rarely applicable in a clinical trial or research setting due to the legal basis for processing.

If you would like to exercise or discuss the rights as explained above please contact us via

11.  Complaints

We will always endeavour to respond and resolve any concerns or complaints that you may have, however, if you are not satisfied with the way that your personal information has been processed, or how we have responded to your queries or requests, you have the right to contact the UK Information Commissioners Office via or any other EU member state Supervisory Authority.

Individuals and information protection supervisory authorities in the EU may also contact our information protection representatives according to Article 27 GDPR:

SerpinPC is a subcutaneously administered novel inhibitor of APC being developed as a potential treatment for hemophilia, regardless of severity or inhibitor status, and may also prevent bleeding associated with other bleeding disorders. Centessa is advancing the registrational program for SerpinPC in hemophilia B, which includes a set of clinical studies with multiple components. PRESent-5, initiated in late 2022, is an observational feeder study to collect prospective observational data for minimum defined periods before switching to dosing subjects in the interventional studies. The interventional studies include PRESent-2 (moderately severe to severe hemophilia B without inhibitors, and severe hemophilia A with and without inhibitors) and PRESent-3 (hemophilia B with inhibitors). Additional information on the trials can be accessed at  (NCT05605678NCT05789524NCT05789537). SerpinPC is an investigational agent that has not been approved by the FDA or any other regulatory authority.
