NCT07444567

Brief Summary

The rationale of the roll-over study (ROSY) is to provide continuous access to study treatment for participants who have completed or exited a parent study and are deemed appropriate for continued benralizumab treatment, as judged by the Investigator, while monitoring long-term safety and tolerability of benralizumab.

Outcome Measures

Primary Outcomes (1)

  • Safety will be evaluated by monitoring and assessing SAEs and non-serious AEs reported throughout the study and until 8 weeks after the last dose of benralizumab

    To provide benralizumab to participants who continue to benefit at the end of the parent clinical study while monitoring long-term safety and tolerability of benralizumab

    From baseline until 8 weeks after the last dose of benralizumab

Study Arms (1)

Benralizumab arm

EXPERIMENTAL

Benralizumab will be administrated as an subcutaneous injection at a frequency in line with that received in the parent study.

Drug: Benralizumab

Interventions

Accessorized Pre-Filled Syringe (Solution for injection).

Also known as: Fasenra
Benralizumab arm

Eligibility Criteria

Age6 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • \. Provision of signed and dated written ICF.
  • \. Participants completing minimum required OLE period of a parent study and judged by the Investigator to benefit from continued treatment.
  • \. Participants without childbearing potential at enrolment must agree to start appropriate contraception if childbearing potential develops during the study and up to 12 weeks after the last dose of study treatment.
  • \. Participants who are unable to access commercially available benralizumab and clinically indicated for continuation.

You may not qualify if:

  • \. Ongoing, unresolved AE requiring interruption of treatment at the end of the prior parent study (ie, when the parent study is either completed or closed) that in the Investigator's opinion would prevent restarting benralizumab.
  • \. Participants who are planning to use live/live-attenuated vaccines.
  • \. Participants who are planning to use biologic therapies, including B-cell therapies with the exception for the treatment of co-morbidities where no alternative medicine is available.
  • \. Participants with any medical condition (such as cancer or viral infections \[hepatitis\]) or psychiatric condition that, in the opinion of the Investigator, could jeopardise or would compromise the participant's ability to participate in this study as determined by the Investigator based on protocol required assessments.
  • \. Concurrently enrolled in any clinical study (other than a parent study).
  • \. Participants who discontinued the parent study prior to completing the minimum OLE or treatment period.
  • \. Local access to commercially available benralizumab.
