Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Participants who have completed the treatment period and have not been prematurely discontinued from IP in the predecessor studies.
- Participants who received their last dose of IP in the predecessor studies within the previous 12 weeks and were not withdrawn from the predecessor study.
- FOCBP (female(s) of childbearing potential) must have a negative urine pregnancy test at Visit 1.
- Participants who are willing to continue using contraceptive methods as agreed to for the predecessor OBERON or TITANIA studies.
- Capable of giving signed informed consent.
Exclusion Criteria:
- Any clinically significant disorder or abnormal findings (clinical, laboratory, instrumental, etc) or major physical and/or cognitive impairment - which, in the opinion of the Investigator, may put the participant at risk because of his/her participation in the study or impact the interpretation of the study results, or otherwise make the participation of the participant inappropriate.
- Participant meeting criteria for IP discontinuation as judged by the Investigator or the Sponsor.
- Concurrent enrolment in other interventional clinical studies or treatment with another IP, with the exception of the OBERON and TITANIA predecessor studies.
Known history of:
- Severe allergic reaction to any monoclonal and polyclonal antibody.
- Allergy or reaction to any component of the IP formulation.
- Chronic use (or expected need for chronic use during the study) of immunosuppressive medications (including, but not limited to, systemic corticosteroids), marketed or investigational biologic, or another prohibited medication.
- Involvement in the planning and/or conduct of the study (applies to both staff employed by the Sponsor and/or staff at the study site).
- Participants who are not able to comply with the study requirements, procedures, and restrictions.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: Tozorakimab Dose 2
Injection subcutaneously Tozorakimab via pre-filled syringe.
|
Participants randomised to either dose regimen in the predecessor studies will be assigned to a single Tozorakimab dose regimen in the PROSPERO study.
|
|
Placebo Comparator: Placebo
Injection subcutaneously with equivalent volume to Tozorakimab via pre-filled syringe.
|
Participants previously randomised to placebo in one of the predecessor studies will be re-randomised in a 1:1 ratio to the active dose of Tozorakimab or placebo.
|
|
Experimental: Tozorakimab Dose 1
Injection subcutaneously Tozorakimab via pre-filled syringe.
|
Participants randomised to either dose regimen in the predecessor studies will be assigned to a single Tozorakimab dose regimen in the PROSPERO study.

|
Up to 104 weeks.
|
|
Time to all-cause death.
Time Frame: Up to 104 weeks.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal. All request will be evaluated as per the AZ disclosure commitment:
https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared.
IPD Sharing Time Frame
AstraZeneca will meet or exceed data availability as per the commitments made to the EFPIA Pharma Data Sharing Principles. For details of our timelines, please rerefer to our disclosure commitment at:
https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.
