A RANDOMIZED, DOUBLE-BLIND TRIAL OF ABATACEPT (CTLA4-IG) FOR THE TREATMENT OF TAKAYASU?S ARTERITIS #MMPMID28133931
Arthritis Rheumatol 2017[Apr]; 69 (4): 846-53 PMID28133931show ga
Objective: To compare the efficacy of abatacept to placebo for the treatment of Takayasu?s arteritis (TAK). Methods: In this multicenter trial, patients with newly-diagnosed or relapsing TAK were treated with abatacept 10 mg/kg IV on days 1, 15, 29, week 8, together with prednisone. At week 12, patients in remission underwent a double-blinded randomization to continue monthly abatacept or switch to placebo. Patients in both study arms received a standardized prednisone taper, reaching 20 mg daily at week 12 with discontinuation of prednisone at week 28 and remained on their randomized assignment until meeting criteria for early termination or until 12 months after enrollment of the last patient. The primary endpoint was duration of remission (relapse-free survival). Results: Thirty-four eligible patients with TAK were enrolled and treated with prednisone and abatacept; 26 reached the week 12 randomization and underwent a blinded randomization to abatacept or placebo. The relapse-free survival at 12 months was 22% for those receiving abatacept and 40% for those receiving placebo (p= 0.853). Treatment with abatacept in patients with TAK enrolled in this study was not associated with a longer median duration of remission (abatacept 5.5 months, placebo 5.7 months). There was no difference in the frequency or severity of adverse events between treatment arms, including infection. Conclusions: In patients with TAK the addition of abatacept to a treatment regimen with prednisone did not reduce the risk of relapse.
