ANZCTR - Registration

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Drugs - Sirukumab
Treatment: Drugs - Placebo to match sirukumab
Treatment: Drugs - Prednisone
Treatment: Drugs - Placebo to match prednisone

Experimental: Part A: Sirukumab, Dose 1+prednisone (6-month taper) - Subjects will receive blinded sirukumab 100 mg subcutaneously (SC) every 2 weeks (q2w) for 52 weeks plus a pre-specified maximum of 6-month oral prednisone taper regimen.

Experimental: Part A: Sirukumab, Dose 1+prednisone (3-month taper) - Subjects will receive blinded sirukumab 100 mg SC q2w for 52 weeks plus a pre-specified maximum of 3-month oral prednisone taper regimen.

Experimental: Part A: Sirukumab, Dose 2+prednisone (6-month taper) - Subjects will receive blinded sirukumab 50 mg SC every 4 weeks (q4w) for 52 weeks plus a pre-specified maximum of 6-month oral prednisone taper regimen.

Placebo comparator: Part A:Placebo to match sirutkumab+prednisone (6-month taper) - Subjects will receive blinded placebo to match sirutkumab q2w for 52 weeks plus a pre-specified maximum of 6-month oral prednisone taper regimen.

Placebo comparator: Part A:Placebo to match sirukumab+prednisone (12-month taper) - Subjects will receive blinded placebo to match sirutkumab q2w for 52 weeks plus a pre-specified maximum of 12-month oral prednisone taper regimen.

Experimental: Part B:Open-label sirukumab 100 mg SC (if applicable) - Subjects completing Part A will receive open label 100 mg SC q2w for a maximum of 52 weeks based on remission status and disease activity at the primary 52-week endpoint or prednisone tapering status of subject during Part A. Methotrexate will be provided to subjects, alone or in addition to sirukumab treatment during Part B, based on the discretion of the investigator.

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

Treatment: Drugs: 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.

Treatment: Drugs: Prednisone
Prednisone will be provided as tablets with dosage level up to-60 mg/day. The prednisone dose for all subjects will be determined by the Investigator and starting doses will be within 20-60 mg prednisone at Baseline (Randomization).

Summary

Brief summary

Sirukumab is a fully human anti-interleukin-6 (IL-6) immunoglobulin G1-kappa with a high affinity and specificity for binding to the human IL-6 molecule that may have therapeutic benefit in the treatment of giant cell arteritis (GCA) by interruption of 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 GCA. The study will be conducted in 2 distinct parts (Part A and Part B) and consists of the following phases: Screening phase, Part A: 52-week double-blind treatment phase, Part B: 104-week extension phase with the option to receive open-label sirukumab based on disease status and a 16-week follow-up phase if applicable.

Approximately 204 subjects with a diagnosis of GCA 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 will be eligible to enter Part B, the 104-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 with active GCA at the end of Part A or those with new onset of GCA flare during the first 52 weeks of Part B will be eligible to receive open-label sirukumab. Subjects will need to have follow-up safety evaluations for at least 16 weeks after receiving the last dose of study drug, applicable only for those who are withdrawn prematurely from the study or whose open-label sirukumab treatment in Part B completes after Week 88.
