Brief Summary:
This study will evaluate the safety and effectiveness of baricitinib in the treatment of giant cell arteritis. All participants will be taking prednisone at the start of the study. The prednisone will be reduced according to a standardized tapering schedule while participants continue to take one tablet of baricitinib daily for 52 weeks.

Condition or disease Intervention/treatment Phase
Arteritis, Giant Cell Drug: Baricitinib Phase 2

Detailed Description:

Baricitinib, an orally administered, potent, selective and reversible inhibitor of JAK1 and JAK2 has shown preliminary safety and efficacy in chronic, immune-mediated inflammatory conditions such as rheumatoid arthritis and psoriasis. This small molecule is uniquely suited as a potential novel therapeutic agent in GCA because of its suppressive effect on both the Th17 (IL-6, IL-23) andTh1 (IL-12, IFN-γ) pathways.

This study will evaluate the safety and tolerability of baricitinib in a population of patients with relapsing GCA. The study is an open-label pilot study assessing the safety and tolerability of baricitinib (4 mg daily, oral, for 52 weeks) in addition to a standardized glucocorticoid taper. It is anticipated that adjunct baricitinib will be safe and well tolerated by patients with GCA and demonstrate preliminary efficacy as measured by reducing inflammatory markers, decreasing steroid requirements and increasing relapse-free survival.

      • Evidence of large-vessel vasculitis by angiography or cross-sectional imaging, including but not limited to magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography-computed tomography (PET-CT) or evidence of large-vessel or temporal artery vasculitis by ultrasound (US).
  2. Relapse with active GCA within 6 weeks of study entry where active disease is defined by an ESR ≥30 mm/hr or CRP ≥10 mg/L AND the presence of at least one of the following:

    • Unequivocal cranial symptoms of GCA (new onset or recurrent localized headache, scalp or temporal artery tenderness, otherwise unexplained mouth or jaw pain upon mastication [i.e., jaw claudication]).
    • Unequivocal symptoms of PMR, defined as shoulder and/or hip girdle pain associated with inflammatory stiffness.
    • Other feature(s) judged by the clinician investigator to be consistent with GCA or PMR flares (e.g. fever of unknown origin, weight loss, fatigue/malaise, etc.)
  3. Clinically stable at baseline visit (study drug initiation) such that the subject is able to safely participate in the standardized taper regimen in the opinion of the investigator.

Exclusion Criteria

  1. Presence of any other autoimmune disease (such as systemic lupus erythematosus, rheumatoid arthritis, inflammatory arthritis, other vasculitides, scleroderma, polymyositis, dermatomyositis, or other similar systemic connective tissue diseases).

Use of parenteral (IV or IM) antimicrobials (antibacterial, antifungals, antivirals, or antiparasitic agents) within 60 days of baseline or oral antimicrobials within 30 days of baseline visit for treatment of an active infection. This does not include the use of antibiotics for prophylaxis against pneumocystis pneumonia since this is considered standard of care for patients on prednisone ≥ 20 mg/day for longer than 3 consecutive months.
  14. Have had symptomatic herpes zoster infection within 12 weeks prior to screening.
  15. Have a history of disseminated/complicated herpes zoster [for example, multidermatomal involvement, ophthalmic zoster or Central Nervous System (CNS) involvement]

  17. Have known or documented diagnosis of human immunodeficiency virus (HIV).
  18. Have known or documented primary immunodeficiency.
  19. Have had household contact with a person with active tuberculosis (TB) and did not receive appropriate and documented prophylaxis for TB.
  20. Have had evidence of active TB or have previously had evidence of active TB and did not receive appropriate and documented treatment.
  21. Have evidence of latent TB as documented by a local lab positive QuantiFERON®-TB Gold test and a normal chest x-ray, unless a patient completes at least 4 weeks of appropriate treatment prior to study entry and agrees to complete the remainder of treatment while in the trial.

    1. If the QuantiFERON®-TB Gold test results are positive, the patient will be considered to have latent TB and will be excluded. If the test is indeterminate, the test may be repeated once within 2 weeks of the initial value. If the repeat test results are again not negative, the subject will be considered to have latent TB (for purposes of this study) and will be excluded.
    2. Exceptions include subjects with a history of active or latent TB who have documented evidence of appropriate treatment and with no history of re-exposure since their treatment was completed. (Such subjects would not be required to undergo the protocol specific TB testing, but would require a baseline chest x-ray).
  22. Have a positive test for Hepatitis B Virus (HBV) defined as:

    1. Positive for hepatitis B surface antigen (HBsAg), or
    2. Positive for anti-hepatitis B core antibody (HBcAb) If any of the Hepatitis B tests have an indeterminate result, confirmatory testing will be performed by an alternate method.
  23. Have Hepatitis C Virus (HCV) (positive for anti-hepatitis C antibody with confirmed presence of HCV).
  24. Have any of the following specific abnormalities on screening tests:
