Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Rozibafusp Alfa

Placebo

Arm Description

Participants will receive rozibafusp alfa administered subcutaneously once every 2 weeks for up to 10 weeks (6 doses). Rozibafusp alfa doses will range from 70 to 420 mg. Escalation to a higher dose cohort will be contingent on a review indicating that the previous dose regimen has been found to demonstrate an acceptable safety and tolerability profile at a dose level review meeting (DLRM).

Participants will receive matching placebo to rozibafusp alfa administered subcutaneously once every 2 weeks for up to 10 weeks (6 doses).

Outcomes

Primary Outcome Measures

Number of Participants With Treatment-emergent Adverse Events
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.

Secondary Outcome Measures

Time to Maximum Observed Concentration (Tmax) of Rozibafusp Alfa
Maximum Observed Serum Concentration (Cmax) of Rozibafusp Alfa
Area Under the Concentration-time Curve From 0 to 14 Days Postdose (AUC0-tau) for Rozibafusp Alfa
Area Under the Concentration-time Curve From Time Zero to Infinity (AUC0-inf) for Rozibafusp Alfa
Terminal Half-life of Rozibafusp Alfa
Accumulation Ratio of AUCtau
Accumulation ratio is the ratio of AUCtau after the last dosing interval (week 10) divided by AUCtau after the first dosing interval (day 1).
Accumulation Ratio of Cmax
Accumulation ratio is the ratio of Cmax after the last dosing interval (week 10) divided by Cmax after the first dosing interval (day 1).

12. IPD Sharing Statement

Plan to Share IPD
Yes
IPD Sharing 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.
