Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Treatment Emergent Adverse Events (TEAEs)
Time Frame: From Day 1 until the Final Study Visit (up to Month 49)
TEAEs were defined as an AE that occurs after a participant's initial treatment zilucoplan start for this study (RA101495-01.202) that was not present at the time of treatment start, or an AE that increases in severity after treatment start in this study, if the event was present at the time of treatment start.
From Day 1 until the Final Study Visit (up to Month 49)
Percentage of Participants With Serious TEAEs
Time Frame: From Day 1 until the Final Study Visit (up to Month 49)
Serious Adverse event (SAE) was defined as any untoward medical occurrence that:• results in death, • is life-threatening threatening (note that this refers to an event in which the participant was at risk of death at the time of the event; it does not refer to an event that hypothetically might have caused death if it were more severe), • requires hospitalization or prolongation of existing hospitalization, • results in persistent or significant disability/incapacity, and • results in a congenital anomaly/birth defect.
From Day 1 until the Final Study Visit (up to Month 49)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
