A Multicenter, Open-Label, Long-Term Treatment Study of Intravenously Administered BIIB092 in Patients With Progressive Supranuclear Palsy Who Participated in Study CN002003

The purpose of this study is to evaluate the long-term safety and tolerability of multiple intravenous (IV) infusions of BIIB092 in participants with Progressive Supranuclear Palsy (PSP). The study will also assess the pharmacodynamic (PD) effects of BIIB092 on cerebrospinal fluid (CSF) N-terminal tau, pharmacokinetics (PK), and immunogenicity of BIIB092 in participants with PSP.

This study, previously posted by Bristol-Myers Squibb, has transitioned to Biogen under a licensing agreement.

         7. Any other sound medical, psychiatric, and/or social reason as determined by the investigator

         8. Known history of human immunodeficiency virus.

         9. Evidence of organ dysfunction or significant deterioration from prior values in CN002003 beyond what is consistent with the target population or that would place the patient at increased risk or risk of early study discontinuation.

         10. Inability to be venipunctured and/or tolerate venous access.

         11. History of allergy, hypersensitivity, or serious adverse reaction to monoclonal antibodies or related compounds or allergy to any of the components of the study drug
