Updated March 03, 2015.
What Is Simponi?
Simponi (golimumab) is a TNF-alpha blocker. Simponi, alone or in combination with methotrexate, was approved by the FDA on April 24, 2009 for the treatment of moderate to severe rheumatoid arthritis, active psoriatic arthritis (alone or with methotrexate), and active ankylosing spondylitis.
How Is Simponi Administered?
Simponi is given by subcutaneous injection (under the skin) once monthly.
It is available in two dosage forms -- an autoinjector, known as the Simponi SmartJect, or as a pre-filled syringe.
What Is TNF-alpha?
TNF-alpha (tumor necrosis factor-alpha) is a cytokine, essentially, a molecular messenger between cells that plays a role in the inflammatory process. Excess TNF-alpha production by the body has been linked to several diseases and conditions, including rheumatoid arthritis (RA).
How Has Simponi (Golimumab) Performed in Clinical Trials?
In clinical trials, patients who received Simponi for either rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis showed improvement in signs and symptoms. The study results were based on more than 2,000 patients involved in five pivotal phase III trials.
