Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Administered by subcutaneous injection once every 2 weeks.

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
Number of Participants With Treatment-emergent Adverse Events
Time Frame: From first dose of study drug to 24 weeks after last dose (up to 34 weeks).

An adverse event (AE) is defined as any untoward medical occurrence in a clinical trial subject, including worsening of a pre-existing medical condition and clinically significant changes in laboratory test results and physical exam findings. The event does not necessarily have a causal relationship with study treatment.

AEs were graded for severity according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4, where Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe or medically significant, Grade 4 = Life-threatening, and Grade 5 = Death.

A serious adverse event is defined as an AE that met at least 1 of the following serious criteria:

  • fatal;
  • life threatening;
  • required in patient hospitalization or prolongation of existing hospitalization;
  • resulted in persistent or significant disability/incapacity;
  • congenital anomaly/birth defect;
  • other medically important serious event. The investigator assessed whether each AE was related to study drug.
From first dose of study drug to 24 weeks after last dose (up to 34 weeks).

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.

YES

IPD Plan Description

De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request

IPD Sharing Time Frame

Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

IPD Sharing Access Criteria

Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
