Study information

Scientific title


Study hypothesis

Can predictors of reponse to anti-Tumour Necrosis Factor (TNF) therapy be identified by immunohistochemical analysis of synovial tissue obtained before initiation of treatment?

Ethics approval

Approval received from the Medical ethical committee of the Academic Medical Center/University of Amsterdam on the 14th February 2001 (ref: MEC 01/003).

Study design

Multicentre phase IV prospective study

Primary study design


Secondary study design


Trial setting

Not specified

Trial type


Patient information sheet


Rheumatoid arthritis


Infliximab therapy (3 mg/kg intravenous [i.v.]) at week zero, two, six, 14 and every eight weeks.

Clinical efficacy assessments are performed at baseline and subsequently every four weeks up to week 24. Serum samples are drawn on these visits. At baseline synovial biopsies are obtained from a maximally inflamed joint.

Intervention type



Phase IV

Drug names


Primary outcome measures

1. Primary immunohistological outcome: TNF-alpha expression in synovial tissue as shown by immunohistochemistry and quantified by digital image analysis
2. Primary clinical outcome: clinical response at week 16 assessed using the DAS 28

Secondary outcome measures

Secondary immunohistological outcome: analysis of the synovial cell infiltrate, and cytokines other than TNFalpha.

Participant inclusion criteria

1. Men/women suffering from rheumatoid arthritis, based on the American Rheumatism Association (ARA) 1987 criteria, who failed at least one Disease Modifying Anti-Rheumatic Drug (DMARD) including methotrexate, will be included in the study
2. Patients in ARA functional classes I, II, and III may be included
3. In addition the patients must fulfill the following criteria at baseline:
a. Disease Activity Score (DAS 28) more than 3.2
b. patients global evaluation of his/her rheumatoid condition assessed as fair, poor or very poor and
investigators global evaluation of patients rheumatoid condition assessed as fair, poor or very poor
c. more than 18 years of age and less than or equal to 85 years
d. use concurrent methotrexate treatment (5 - 30 mg/week; stable since at least 28 days before initiation) during the study. Subjects may be taking nonsteroidal anti-inflammatory drugs, provided the dose and frequency have been stable for at least 28 days. Subjects may be receiving prednisone therapy of less than or equal to 10 mg/day provided that the dosage has been stable for at least two months prior to entry
