A Study to Evaluate the Pharmacokinetics, Safety and Immunogenicity of BIIB800 Subcutaneously (SC) Compared to Actemra® in Healthy Male Participants

Phase 1
Completed
Conditions
Healthy Volunteer
Interventions
Registration Number
NCT06262477
Lead Sponsor
Biogen
Brief Summary

The primary objective of the study is to show equivalence in pharmacokinetics (PK) of BIIB800 and Actemra following SC administration of a single dose to healthy male participants. The secondary objective of the study is to evaluate PK over time, clinical safety, pharmacodynamic (PD) profiles and immunogenicity of BIIB800 and Actemra.

  • History of angioedema.
  • A positive diagnostic tuberculosis test result within 35 days prior to Day -1, defined as a positive QuantiFERON® test result or 2 successive indeterminate QuantiFERON test results.
  • Any prior exposure to tocilizumab or to any other agent directly acting on IL-6 or on its receptors including investigational products (e.g., siltuximab, sarilumab etc.).
  • Administration of immunoglobulins for anti-tetanus and anti-rabies post-exposure prophylaxis within 3 weeks prior to administration of study drug.
  • Any live or attenuated immunization or vaccination given within 30 days prior to Day -1 or planned to be given during the study period.
