A Study of the Safety and Efficacy of Golimumab in Subjects With Rheumatoid Arthritis That Are Methotrexate-Naive

2014-08-27 03:47:11 | BioPortfolio

Summary

The purpose of this study is to evaluate the efficacy and safety of golimumab, alone or in combination with methotrexate, as compared to methotrexate alone in rheumatoid arthritis subjects who have not been previously treated with methotrexate.

Description

Golimumab is a fully human protein (antibody) which binds to tumor necrosis factor (TNFα). TNFα is increased in patients with rheumatoid arthritis (RA), and plays a major role in causing the joint pain, swelling, and damage from RA. Other marketed drugs that target TNFα (anti-TNFα drugs) have been shown to be effective in reducing the symptoms, signs, and joint damage of RA, but have limitations with respect to safety and ease of use. This is a randomized, double-blind, placebo-controlled trial of the efficacy and safety of a new anti-TNFα drug, golimumab, at 2 doses, injected under the skin every 4 weeks, alone or in combination with methotrexate, compared with methotrexate alone, in subjects with active RA who have not been previously treated with methotrexate. The study hypothesis is that golimumab, alone or in combination with methotrexate, will be more effective in treatment of RA than methotrexate alone, as measured by the American College of Rheumatology (ACR) response criteria and change from baseline in van der Heijde Modified Sharp (vdH-S) score, without causing unacceptable significant adverse effects. The ACR response criteria were designed to determine the percentage of subjects who have achieved a certain level of improvement in their signs and symptoms of rheumatoid arthritis. The vdH-S score is a measurement of the amount of joint damage in a subject as seen by x-ray. Other secondary measures of effectiveness include the Health Assessment Questionnaire (HAQ), which is a series of questions that measure a subject's impairment in physical function caused by RA.

Golimumab 50 mg or 100 mg, or placebo injections under the skin every 4 weeks until Week52. Methotrexate (MTX) or placebo capsules will be given in addition. At Week52, subjects on MTX alone with joint pain or swelling get golimumab 50mg, and all subjects receive golimumab for about 4 more years.

Medical and Biotech [MESH] Definitions

Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

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.

An antineoplastic antimetabolite with immunosuppressant properties. It is an inhibitor of TETRAHYDROFOLATE DEHYDROGENASE and prevents the formation of tetrahydrofolate, necessary for synthesis of thymidylate, an essential component of DNA.
