Study to Evaluate Oral BIIB061 Added to Interferon-beta1 (IFN-β1) or Glatiramer Acetate in Relapsing Multiple Sclerosis (RMS)

NCT ID: NCT04079088

Last Updated: 2023-06-01

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-06-30
• Study Completion Date: 2024-09-18

Brief Summary

The primary objectives of the study are to evaluate the safety of BIIB061 versus placebo in participants with Relapsing Multiple Sclerosis (RMS), and to evaluate the efficacy of BIIB061 to improve disability outcome versus placebo in participants with RMS.

The secondary objectives of the study are to evaluate the effects of BIIB061 versus placebo on brain magnetic resonance imaging (MRI) markers of remyelination and axon preservation in chronic Multiple Sclerosis lesions and to evaluate the effects of BIIB061 versus placebo on additional measures of improved disability outcome.

Detailed Description

BIIB061's unique mechanism of action may provide a pharmacological intervention to overcome the failure of remyelination in all forms of multiple sclerosis by blocking mechanisms that prevent differentiation of oligodendrocytes progenitors.

Eligibility Criteria

Inclusion Criteria

• Diagnosed with relapsing-remitting multiple sclerosis (RRMS) or secondary progressive multiple sclerosis (SPMS)
• Have a Baseline Expanded Disability Status Scale (EDSS) score of 2.0 to 6.0
• Have a MS disease duration of ≤20 years from first MS symptom(s)
• Must have at least one of the following occurring within 12 months prior to

Day 1/Baseline:

(a) ≥1 clinical relapse(s) or objective disability worsening (as per treating neurologist's judgment) (b) ≥1 Gadolinium (Gd)-enhancing T1 lesion(s) on brain or spinal cord Magnetic Resonance Imaging (MRI) (c) ≥1 new T2 lesion(s) on brain or spinal cord MRI (the reference scan used to detect new T2 lesion formation has to be ≤12 months prior to Day 1/Baseline)

• Must have been taking one of the following disease-modifying therapy (DMTs) at a stable dose for at least 12 weeks prior to Day 1/Baseline:

1. Interferon-beta1 (IFN-β1): Avonex, Plegridy, Betaferon/Betaseron, Extavia, or Rebif

2. Glatiramer acetate (Copaxone or Glatopa).

Exclusion Criteria

• A documented history of clinically significant persistent neutralizing antibody against IFN-β1 (applicable only for participants entering the study with IFN-β1 as a background DMT), in the opinion of the Investigator
• Contraindications to MRI, for example, presence of pacemakers or other implanted metal devices (excluding dental braces), an allergy to Gd, renal impairment, or claustrophobia that cannot be medically managed
• History or a positive test result at Screening for human immunodeficiency virus
• Current hepatitis C infection (defined as positive hepatitis C virus [HCV] antibody and detectable HCV Ribonucleic acid (RNA)). Participants with positive HCV antibody and undetectable HCV RNA are eligible to participate in the study (United States [US] Centers for Disease Control and Prevention)
• Current hepatitis B infection (defined as positive for hepatitis B surface antigen [HBsAg] or total hepatitis B core antibody [anti-HBc]). Participants with immunity to hepatitis B from previous natural infection (defined as negative HBsAg, positive anti-HBc, and positive hepatitis B surface antibody [anti-HBs]) or vaccination (defined as negative HBsAg, negative anti-HBc, and positive anti-HBs) are eligible to participate in the study
• History of systemic hypersensitivity reaction to BIIB061
• History of suicidal ideation or an episode of clinically severe depression (as determined by the Investigator) within 12 weeks of screening
• Clinically significant (as determined by the Investigator) 12-lead ECG or laboratory assessment abnormalities
• Any condition affecting study treatment absorption (e.g., gastrectomy)
• Treatment with statins (3-hydroxy-3-methyl-glutaryl coenzyme A reductase inhibitors) or proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors (e.g., alirocumab and evolocumab) within 8 weeks prior to Day 1/Baseline
• Inability or unwillingness to comply with study requirements
• Other unspecified reasons that, in the opinion of the Investigator or Biogen that make the participant unsuitable for enrollment.

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 55 Years
