Clinical Trial Summary

The Division of Rheumatology at University of California San Francisco is conducting a research study on the treatment of ankylosing spondylitis (AS) with a new therapy currently used for people with other forms of arthritis. The drug, called Enbrel (or etanercept), is a protein that is given twice weekly by injection underneath the skin. It blocks the action of tumor necrosis factor-alpha (TNF-alpha), a substance that may be involved in AS, rheumatoid arthritis, and other inflammatory conditions. We will randomly assign patients to receive either the drug or a placebo (inactive treatment) for 4 months. The results we will monitor include morning stiffness, spinal mobility, activities of daily life, and safety of the drug.


Clinical Trial Description

In this Phase II clinical trial we will use tumor necrosis factor receptor p75 fusion protein (TNFR:Fc, or etanercept) to treat patients with ankylosing spondylitis (AS). TNFR:Fc is an antagonist of tumor necrosis factor (TNF), a cytokine that researchers have shown to play a possible role in disease pathogenesis of ankylosing spondylitis, rheumatoid arthritis, and vasculitis, as well as other inflammatory conditions.

TNFR:Fc consists of two molecules of the extracellular portion of the p75 receptor, each consisting of 235 amino acids. The two receptors are fused to the Fc portion of human IgG1, which consists of 232 amino acids. The gene fragments encoding the truncated TNFR and the Fc portion of human IgG1 are expressed in a Chinese hamster ovary cell line.

Recent observations from animal and human studies suggest that tumor necrosis factor-alpha (TNF-alpha) may play a role in disease activity in AS and other seronegative spondyloarthropathies. This study aims to test the efficacy of TNFR:Fc used in conjunction with standard medications in the treatment of AS. We will give patients either 25mg of TNFR:Fc or placebo subcutaneously twice a week for 4 months. Outcome measures will include measures of function, pain, morning stiffness, patient global assessment, and swollen joint count, as well as safety measures. ;
