Natalizumab Subcutaneous Immunogenicity and Safety Study

Phase 2
Terminated
Conditions
Relapsing Multiple Sclerosis
Interventions
Registration Number
NCT02142192
Lead Sponsor
Biogen
Brief Summary

The primary objective of this study is to evaluate the immunogenicity of natalizumab (BG00002) 300 mg subcutaneous (SC) administered to participants with relapsing multiple sclerosis (RMS). The secondary objectives of the study are to evaluate the safety of natalizumab SC injections and to evaluate the efficacy of natalizumab SC injections on relapses and on new magnetic resonance imaging (MRI) lesions.

Primary Outcome Measures
NameTimeMethod
Proportion of participants with persistent anti-natalizumab antibodies48 weeks

Persistent anti-natalizumab antibodies are defined as 2 positive anti-natalizumab test results separated by at least 6 weeks, with at least 1 positive test result occurring at or after the Week 24 Visit.

Secondary Outcome Measures
NameTimeMethod
Proportion of participants with transient anti-natalizumab antibodies48 weeks
Proportion of participants with post-injection adverse events (AEs)48 weeks

Including hypersensitivity reactions, anaphylactic reactions and other AEs occurring within 1 hour after SC natalizumab dosing.

Proportion of participants with clinical relapse48 weeks

This may include new or enlarging T2 lesion(s), as determined by magnetic resonance imaging (MRI). Clinical relapse is 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 neurologist.

Proportion of participants with gadolinium (Gd) enhancing lesion(s) as assessed by MRI.48 weeks
Proportion of Participants that experience Adverse Events and Serious Adverse Eventsup to 56 weeks
