A Randomized Double-Blind, Placebo Controlled Trial of Abatacept (CTLA4-Ig) in Giant Cell Arteritis (ABAGART)

Sponsor

University of Pennsylvania

Enrollment

78 participants

Start Date

Mar 29, 2021

Study Type

INTERVENTIONAL

Conditions

Giant Cell Arteritis

Summary

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.

Interventions

DRUGAbatacept

Participants randomized to abatacept will receive abatacept 125 mg administered by subcutaneous injection once a week. Participants randomized to either the abatacept or the placebo arm who experience a non-severe disease relapse, non-severe disease worsening, or who have not achieved remission by month 3 will have the option of entering an open-label trial period whereby they would receive open-label abatacept for up to 12 months.

DRUGPlacebo

Participants randomized to placebo will receive a sterile placebo solution administered by subcutaneous injection once a week. Participants randomized to either the abatacept or the placebo arm who experience a non-severe disease relapse, non-severe disease worsening, or who have not achieved remission by month 3 will have the option of entering an open-label trial period whereby they would receive open-label abatacept for up to 12 months.
