The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

* Female participant must have a medically confirmed qualifying pregnancy (prospectively or retrospectively identified).

* Participant informed consent (written or e-consent per local regulations or ethics committee requirements) must be obtained prior to the participant's enrollment. If the participant is a minor, consent must be obtained from the parent or legal guardian, with assent from the minor (as locally appropriate).

* Willing to provide contact information for the participant.

* Willing to authorize HCP(s) to release maternal and infant medical information to the study, upon request, if applicable to current local regulations.

* Diagnosed with an indication for which Ultomiris is approved, based on HCP or medical records.

* Exposed to Ultomiris at any point during the defined exposure window based on HCP or medical record documentation. (If exact exposure dates are unknown, the reporter must be able to specify or estimate trimester or timing of exposure \[prior to conception as LMP+14 days, or during breastfeeding\].)

* Use of Ultomiris per local product information (i.e., United States Prescribing Information \[USPI\] or summary of product characteristics \[SmPC\])

Exclusion Criteria:

* Participants who are unable to provide consent or assent (as locally appropriate) (e.g., diagnosed with severe psychiatric conditions or severe intellectual disabilities) will be excluded from this study

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
