Safety and Efficacy of Extracorporeal Photoimmune Therapy With UVADEX for the Treatment of Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a systemic autoimmune inflammatory disorder that can cause substantial pain and joint tenderness, significant joint damage, and serious disability. The treatment goals are minimization of the signs and symptoms of the disease, and the reduction of irreversible joint damage.
As the understanding of the pathophysiological mechanisms underlying RA is elucidated, the opportunity to target specific inflammatory processes with new therapies has improved. Rheumatoid arthritis is a T cell-mediated autoimmune disease and there are various therapies, including newer experimental therapies, which target either the activation of T cells or the neutralization of their effector mechanisms. These newer therapies have shown benefit in human and animal models of RA. Extracorporeal photoimmune therapy (ECP) has been shown to be safe and effective in the palliative treatment of the skin manifestations of cutaneous T cell lymphoma. Experimental studies have also demonstrated activity of ECP treatment in several T cell mediated diseases including graft versus-host disease, rejection after organ transplantation, and selected autoimmune diseases.
This study will evaluate a cell-based therapy (ECP) in patients who have an inadequate response to disease-modifying antirheumatic drugs (DMARDs) and biological agents to determine if ECP treatment can reduce the signs and symptoms of RA in this refractory patient population.

Medical and Biotech [MESH] Definitions
A process in which peripheral blood is exposed in an extracorporeal flow system to photoactivated 8-methoxypsoralen (METHOXSALEN) and ultraviolet light - a procedure known as PUVA THERAPY. Photopheresis is at present a standard therapy for advanced cutaneous T-cell lymphoma; it shows promise in the treatment of autoimmune diseases.
Rheumatoid arthritis of children occurring in three major subtypes defined by the symptoms present during the first six months following onset: systemic-onset (Still's Disease, Juvenile-Onset), polyarticular-onset, and pauciarticular-onset. Adult-onset cases of Still's disease (STILL'S DISEASE, ADULT-ONSET) are also known. Only one subtype of juvenile rheumatoid arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.
A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis.
Systemic-onset rheumatoid arthritis in adults. It differs from classical rheumatoid arthritis in that it is more often marked by acute febrile onset, and generalized lymphadenopathy and hepatosplenomegaly are more prominent.
Antibodies found in adult RHEUMATOID ARTHRITIS patients that are directed against GAMMA-CHAIN IMMUNOGLOBULINS.
