Clazakizumab 25 mg
Clazakizumab 25 mg: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Clazakizumab 25 mg arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of 25 mg clazakizumab will be given no later than day 3.
Clazakizumab 12.5 mg
Clazakizumab 12.5 mg: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Clazakizumab 12.5 mg arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of 12.5 mg clazakizumab will be given no later than day 3.
Placebo
Placebo: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Placebo arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of placebo will be given no later than day 3.

Measure
Clazakizumab 25 mg
n=78 participants at risk
Clazakizumab 25 mg: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Clazakizumab 25 mg arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of 25 mg clazakizumab will be given no later than day 3.
Clazakizumab 12.5 mg
n=26 participants at risk
Clazakizumab 12.5 mg: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Clazakizumab 12.5 mg arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of 12.5 mg clazakizumab will be given no later than day 3.
Placebo
n=74 participants at risk
Placebo: The first dose will be administered as soon as possible after the patient is enrolled and randomized into the Placebo arm. The route of administration will be intravenous. Each dose will be administered as an infusion that is run over 30 minutes. Serum CRP will be evaluated at baseline and on days 1 and 2 following clazakizumab administration. If the CRP does not decrease by 50% within 36-48 hours after the first dose, a second dose of placebo will be given no later than day 3.
