Olumiant® (baricitinib): Safety in Patients with Comorbid Demyelinating Disorders

Analysis of the safety of BARI in patients with moderate to severe RA and comorbid demyelinating disorders have not been conducted.


Exclusion Criteria Related to Demyelinating Disorders in the Baricitinib Clinical Trials

Demyelinating disorders, as defined by the Standardized MedDRA Demyelination Query (SMQ) 20000154 narrow preferred terms, were not specific exclusion criteria in the 4 phase 3 BARI clinical trials, RA-BEAM, RA-BEACON, RA-BUILD, and RA-BEGIN. However, patients were excluded if they had a history or presence of a serious or unstable illness that, in the opinion of the investigator, could

  • constitute a risk when taking an investigational product, or
  • interfere with the interpretation of data.1

See Standardized MedDRA Demyelination Query (SMQ) 20000154 Narrow Preferred Terms for a listing of the narrow preferred terms used to define demyelinating disorders.
