Efficacy and Safety of Daclizumab in Participants With RRMS Switching From Natalizumab (SUSTAIN)

September 25, 2019 updated by: Biogen

A Phase 3b, 12-month, Open-label, Multicenter Study to Evaluate the Efficacy and Safety of BIIB019, Daclizumab, in Subjects With Relapsing-Remitting Multiple Sclerosis (RRMS) Switching From Natalizumab (SUSTAIN)

The primary objective of the study is to evaluate the effects of treatment with daclizumab on the proportion of participants relapse-free at 6 months in Relapsing-Remitting Multiple Sclerosis (RRMS) participants, who switched from treatment with natalizumab to daclizumab due to safety concerns. The secondary objectives of this study in this study population are to evaluate the effects of daclizumab on the following: 1) Multiple Sclerosis (MS) relapse activity including the annualized relapse rate (ARR) and the proportion of participants experiencing relapses requiring hospitalization and/or steroid treatment; 2) MS-related outcomes measured using magnetic resonance imaging (MRI); 3) Safety and tolerability in participants previously treated with natalizumab.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

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 Relapse-free at Month 6
Time Frame: Month 6
Relapses were defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Examining Neurologist. The Kaplan-Meier estimate of the percentage of participants relapse-free at Month 6 is reported.
Month 6

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.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Relapse-free at Month 12
Time Frame: Month 12
Relapses were defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Examining Neurologist.
Month 12
Percentage of Participants Experiencing Relapse Requiring Hospitalization and/or Steroid Treatment at Month 12
Time Frame: Month 12
Relapses were defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Examining Neurologist.
Month 12
Annualized Relapse Rate (ARR) at Month 12
Time Frame: Month 12
Relapses were defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Examining Neurologist. The ARR was calculated by tabulating the total number of relapses experienced in the group divided by the number of days up to the end of Month 12, and the ratio then multiplied by 365.
Month 12
Number of Participants With New Gadolinium-Enhanced (Gd+) and T1 Hypointense Lesions at Months 6 and 12
Time Frame: Months 6 and 12
New Gadolinium-Enhanced (Gd+) and T1 Hypointense Lesions were assessed using magnetic resonance imaging (MRI).
Months 6 and 12
Number of Participants With New and Newly Enlarged T2 Hypointense Lesions at Months 6 and 12
Time Frame: Months 6 and 12
New and newly enlarged T2 Hypointense Lesions were measured by MRI.
Months 6 and 12
Permanent Discontinuation Rate of Daclizumab at Month 12
Time Frame: Month 12
Permanent Discontinuation Rate was calculated as the ratio of number of participants who had permanently discontinued daclizumab prior to Month 12 over the total number of participants who received at least 1 dose of daclizumab in the study.
Month 12
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: First dose of study drug to within 30 days of last dose (up to 11 months)
An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death or in the view of the Investigator, places the participant at immediate risk of death or requires inpatient hospitalization or prolongation of existing hospitalization or results in persistent or significant disability or results in a birth defect.
First dose of study drug to within 30 days of last dose (up to 11 months)
Number of Participants With Clinically Relevant Shifts in Laboratory Assessments
Time Frame: First dose of study drug to within 30 days of last dose (up to 11 months)
Clinical Laboratory assessments were tests of Chemistry and Hematology. The investigator determined if any of the laboratory results were clinically relevant shifts from Baseline.
First dose of study drug to within 30 days of last dose (up to 11 months)
