Efficacy and Safety Study of Sirukumab in Subjects With Polymyalgia Rheumatica

NCT02899026 · Status: WITHDRAWN · Phase: PHASE3 · Type: INTERVENTIONAL

Summary

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safety evaluations for at least 16 weeks after receiving the last dose of study drug, applicable for those who have withdrawn prematurely from the study or who have completed Part A but are not eligible for Part B.

Interventions

DRUG

Sirukumab

Sirukumab will be provided as 1 millilitre (mL) Pre-filled Syringe (PFS), containing 100 mg/mL or 50 mg/mL of sirukumab, fitted with a spring-powered, disposable autoinjector device for single use SC administration of liquid biologic drug

DRUG

Placebo to match sirukumab

Placebo to match sirukumab will be provided as 1.0 mL PFS fitted with a spring-powered, disposable autoinjector device for single use SC administration of liquid biologic drug

DRUG

Prednisone /Prednisone placebo

Prednisone will be provided as tablets with dosage level up to 20 mg/day. All subjects will receive 20 mg prednisone at Baseline (Randomization) and follow predefined taper regimen (6 weeks or 52 weeks) based on treatment assignment. Placebo to match prednisone will be provided as tablets
