Tocilizumab Dose-tapering & Interruption in Patients With Giant Cell

Status Recruiting

Clinical Trial Summary

Interleukin-6 (IL-6), a pro-inflammatory cytokine, has been found to have a crucial role in the pathogenesis of Giant cel arteritis (GCA). Based on this rationale, several recent studies demonstrated the efficacy of tocilizumab (TCZ), an anti-IL-6 targeted monoclonal antibody, for the treatment of patients with refractory GCA. Confirming previous reports,in a recent retrospective study the investigators successfully treated 10 patient with refractory GCA with TCZ. All patients achieved a complete disease remission evaluated by clinical, laboratory, and positron emission tomography (PET). In a considerable number of GCA patients treated with corticosteroids (CS) the therapy may be interrupted with no disease flares. No data are available on the management of patients achieving the remission with TCZ.

Clinical Trial Description

Study design. Open-label, prospective, pilot study on patients with giant cell arteritis (GCA) resistant to corticosteroids (CS) .

Setting. Rheumatology department, Hospital of Prato, Prato, Italy. Treatment. All refractory GCA patients with or without involvement of aorta and its thoracic branches treated with intravenous TCZ at the dose of 8 mg/Kg/monthly or subcutaneous TCZ at the dose of 162 mg/weekly who achieved a stable remission over a 6-month period should receive reduced TCZ doses with the following schedules: intravenous TCZ tapering to 2 mg/Kg/monthly with drug withdrawal at month 4, and subcutaneous TCZ monthly reduction through the lengthening of injection intervals every 2, 3 , and 4 weeks, and with drug interruption at month 4.

Primary end-point. To investigate the maintenance of clinical remission after TCZ interruption over a 6-month follow-up period.

Secondary end-points. To assess the maintenance of clinical remission during the treatment, to evaluate the role of acute-phase reactants and PET in predicting the relapse and remission, and to assess the occurrence of adverse event (AEs). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
