Abnormal blood pressure [as determined by the investigator] 3. Symptomatic herpes zoster within 3 months prior to screening 4. Evidence of active or latent tuberculosis (TB) as documented by medical history and examination, chest x-rays (posterior anterior and lateral), and TB testing: either a positive tuberculin skin test (TST; defined as a skin induration <5 mm at 48 to 72 hours, regardless of Bacillus Calmette-Guerin (BCG) or other vaccination history) or a positive (not indeterminate) QuantiFERON®-TB Gold test NOTE: The choice to perform a TST or a QuantiFERON-TB Gold test will be made by the investigator according to local licensing and standard of care. The QuantiFERON-TB Gold test can only be used in countries where it is licensed, and the use of this test is dependent on previous treatment(s). This test may not be suitable if previous treatment(s) produced significant immunosuppression. 5. Significant allergies to humanized monoclonal antibodies 6. Clinically significant multiple or severe drug allergies, intolerance to topical corticosteroids, or severe post-treatment hypersensitivity reactions (including, but not limited to, erythema multiforme major, linear immunoglobulin A (IgA) dermatosis, toxic epidermal necrolysis, and exfoliative dermatitis) 7.

Evidence or history of significant active bleeding or coagulation disorder or use of non-steroidal anti-inflammatory drugs or other drugs that affect coagulation or platelet function within 14 days prior to lumbar catheter insertion 12. Allergy to lidocaine (Xylocaine®) or its derivatives 13. Medical or surgical conditions for which lumbar puncture is contraindicated <Start of common text> 14. ALT and bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%) 15. Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones) 16. [QTc >450 msec for male participants] [or >470 msec for female participants] NOTES: The QTc is the QT interval corrected for heart rate according to Bazett’s formula (QTcB), Fridericia’s formula (QTcF), and/or another method. It is either machine-read or manually over-read. The specific formula that will be used to determine eligibility and discontinuation for an individual participant should be determined prior to initiation of the study. In other words, several different formulas cannot be used to calculate the QTc for an individual participant and then the lowest QTc value used to include or discontinue the participant. <End of common text> PRIOR/CONCOMITANT THERAPY 17.

Liver imaging (ultrasound, magnetic resonance, or computerized tomography) and/or liver biopsy to evaluate liver disease; complete liver imaging and/or liver biopsy CRFs 1. Serum bilirubin fractionation should be performed if testing is available. If serum bilirubin fractionation is not immediately available, discontinue study treatment if ALT 3xULN and bilirubin 2xULN. Additionally, if serum bilirubin fractionation testing is unavailable, record the absence/presence of detectable urinary bilirubin on dipstick which is indicative of direct bilirubin elevations suggesting liver injury. 2. All events of ALT 3xULN and bilirubin 2xULN (>35% direct bilirubin) or ALT 3xULN and INR >1.5 may indicate severe liver injury (possible ‘Hy’s Law’) and must be reported as an SAE (excluding studies of hepatic impairment or cirrhosis). The INR measurement is not required and the stated threshold value will not apply to participants receiving anticoagulants. 3. Hepatitis A IgM antibody; hepatitis B surface antigen and hepatitis B Core Antibody (HBcAb); hepatitis C RNA; cytomegalovirus IgM antibody; Epstein-Barr viral capsid antigen IgM antibody (or if unavailable, heterophile antibody or monospot testing); and hepatitis E IgM antibody. 4. PK sample may not be required for participants known to be receiving placebo or non-comparator treatments. Record the date/time of the PK blood sample draw and the date/time of the last dose of study treatment prior to the blood sample draw on the CRF. If the date or time of the last dose is unclear, provide the participant’s best approximation. If the date/time of the last dose cannot be approximated OR a PK sample cannot be collected in the time period indicated above, do not obtain a PK sample.
