Baricitinib in Relapsing Giant Cell Arteritis

Overview

  • Study type

    Interventional
  • Study phase

    II
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

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.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

  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).

  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).
