About this study

This randomized, double-blind, placebo-controlled trial will seek to determine the efficacy of abatacept in GCA. To examine this objective, 62 eligible patients who have newly diagnosed or relapsing GCA within 8 weeks prior to screening will be randomized at a 1:1 ratio to receive subcutaneous abatacept 125mg/week or placebo. Patients who achieve remission will remain on their blinded assignment for 12 months at which time abatacept/placebo will be stopped. Patients who do not achieve remission by Month 3, who experience a relapse within the first 12 months will have the option of receiving open-label abatacept for a maximum of 12 months.
