Efficacy and Safety Study of Sirukumab in Subjects With Polymyalgia Rheumatica
A Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy and Safety of Sirukumab in Subjects With Polymyalgia Rheumatica
Sirukumab is a human anti-IL-6 monoclonal antibody that selectively binds to the cytokine with high affinity that may have therapeutic benefit in the treatment of polymyalgia rheumatica (PMR) by interrupting multiple pathogenic pathways. Sirukumab inhibits IL-6-mediated signal transducer and activator of transcription 3 (STAT3) phosphorylation, resulting in the inhibition of the biological effect of IL-6. This study will evaluate the efficacy and safety of sirukumab to characterize the benefit-to-risk profile of sirukumab in the treatment of active PMR. The study will be conducted in 2 parts (Part A and Part B) and consists of the following phases: Screening phase, Part A: 52-week double-blind treatment phase, Part B: 52-week extension phase with no study drug administration and a 16-week follow-up phase if applicable.
Approximately 150 subjects with a diagnosis of PMR and active disease within 6 weeks of baseline will be randomized into Part A, the 52-week double-blind treatment phase, to receive one of two doses of sirukumab or placebo, each in addition to a pre-specified prednisone taper. The efficacy and safety of sirukumab in sustaining remission will be assessed at Week 52. Subjects completing Part A of the study who are in clinical remission will be eligible to enter Part B, the 52-week extension phase, designed to investigate the long-term maintenance of remission and safety following cessation of sirukumab treatment and to assess long-term corticosteroid use. Subjects will need to have follow-up safety evaluations for at least 16 weeks after receiving the last dose of study drug, applicable for those who have withdrawn prematurely from the study or who have completed Part A but are not eligible for Part B.

Description
Inclusion Criteria:
- Age >=50 years
- Diagnosis of PMR based on the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2012 provisional PMR classification criteria, that is, at the time of PMR diagnosis, subjects should be aged 50 years or older, presenting with new-onset (<12 weeks of diagnosis) bilateral shoulder pain and abnormal acute-phase response, and are required to score 4 or more on the following criteria for the diagnosis of PMR: Morning stiffness duration >45 minutes (2 points) or Hip pain or limited range of motion (1 point) or Absence of rheumatic factor (RF) or anti-citrullinated protein antibody (ACPA) (2 points) or Absence of other joint involvement (1 point).
- Active PMR within 6 weeks of randomization where active disease is defined by an ESR >=30 millimeter (mm)/hour (hr) or CRP >=1 mg/dL within 6 weeks of randomization AND the presence of at least one of the following at screening (within 6 weeks of randomization): Unequivocal symptoms of PMR, defined as shoulder and/or hip girdle pain associated with inflammatory stiffness or Other features judged by the clinician investigator to be consistent with PMR or PMR flares (e.g. fever of unknown origin).
- Receiving oral prednisone 0-25 mg once daily (or equivalent) for PMR treatment at screening. Dosage of oral prednisone or equivalent, during the screening period can remain constant or be adjusted within the range of 0-25 mg prednisone equivalent based on investigator's discretion.

Exclusion Criteria:
- Features consistent with atypical PMR according to the investigator's clinical judgment. Investigators are encouraged to discuss with the medical monitor when there are questions regarding excluding subjects with atypical PMR.
