• Intervention / Treatment: Drug: Placebo; Drug: BIRB 796 BS, low dose; Drug: BIRB 796 BS, high dose

• Study Type: Interventional
• Enrollment (Actual): 170
• Phase: Phase 2

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 75 years (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Male or female from 18 to 75 years of age
• Diagnosis of rheumatoid arthritis (RA) established according to ACR criteria and date of diagnosis > 6 months
• Patient belonging to functional class I, II, or III
• Failure of at least one DMARD due to lack of efficacy or tolerability

• 2 out of the 3 following RA activity criteria: If this criterion is not met at visit 1, the whole set of RA activity criteria can be repeated at visit 2 (Repeated screening)

  • documentation of ≥ 9 swollen joints in a 66 joint count
  • documentation of ≥ 9 tender joints in a 68 joint count
  • C-reactive protein (CRP) ≥ 1.5 mg/dl or erythrocyte sedimentation rate (ESR) ≥ 28 mm/hr (or equivalent of ≥ 24mm/hr according to Panchenkov method)
• Written informed consent in accordance with Good Clinical Practice (GCP) and local legislation given prior to any study procedures, including washout of prohibited medications
• Only for centres participating in the pharmacokinetic (PK) substudy: Written informed consent in accordance with GCP and local legislation for participation in the PK substudy. Refusal to participate in the PK substudy is not an exclusion criterion for participation in the trial

Exclusion Criteria:

• Inflammatory rheumatic disease other than RA
• Treatment failure to a tumor necrosis factor (TNF)-blocking agent. Treatment failure is defined as not achieving at least an ACR 20 response (e.g. in a clinical trial) or - in clinical practice - having the TNF-blocking agent discontinued due to ineffectiveness
• History of vasculitis (characterised by e.g. nail bed hemorrhages or infarcts, vasculitic purpura, ulcers or gangrene, multisensory neuropathy, vasculitic retinopathy or scleritis of eyes). Isolated rheumatoid nodules of the skin are not a criterion for exclusion
• Serologic evidence of active hepatitis B and/or C
• Known HIV-infection
• History of prior tuberculosis infection or suspicion of active infection at screening based on results of chest x-ray not older than 6 months
• History of cardiovascular, renal, neurologic, psychiatric, liver, gastrointestinal, immunologic or endocrine dysfunction if they are clinically significant. A clinically significant disease is defined as one which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study
• Recent history of heart failure (i.e. three years or less) or myocardial infarction (i.e. one year or less) or patients with any cardiac arrhythmia requiring drug therapy
• History of malignant disease in the last 5 years or suspicion of active malignant disease except successfully treated squamous or basal cell carcinoma of the skin
• Screening ECG results outside of the reference range of clinical relevance including, but not limited to QTcB > 480 msec, PR interval > 240 msec, QRS interval > 110 msec according to central ECG evaluation

• Clinically significant abnormal baseline hematology, blood chemistry or urinalysis if the abnormality defines a disease listed as an exclusion criterion or any of the following specific laboratory abnormalities: If this criterion is not met at visit 1, the laboratory assessments can be selectively repeated at visit 2 (Repeated screening)

  • alanine aminotransferase (ALT), aspartate aminotransferase (AST), or total bilirubin greater than upper limit of normal (ULN)
  • alkaline phosphatase, creatinine or white blood cell count greater than 1.5 x ULN
• History of drug or alcohol abuse within the past two years or active drug or alcohol abuse, present alcohol intake more than three drinks per day
• Female of childbearing potential (not 6 months post- menopausal or surgically sterilized) not using an approved form of birth control (hormonal contraceptives, oral or injectable/implantable, intra-uterine device (IUD))
• Inability to comply with the protocol
• Previous enrolment in this trial or previous exposure to BIRB 796 BS in another trial
• Hypersensitivity to trial drug

To be assessed at visit 3 (Baseline):

• Pregnancy (to be excluded by serum and urine beta human chorion-gonadotropin (βHCG)-test in women of childbearing potential) or breast feeding
• Active vasculitis
• Active infection or serious infectious diseases resulting in hospitalisation or requiring systemic anti-infective therapy within the last 4 weeks
• DMARD treatment within the last 4 weeks

• Last dose given within the specified time period for one of the following compounds or drugs:

  • Infliximab (Remicade®): 3 months
  • Adalimumab (D2E7): 3 months
  • Leflunomide: 3 months. If cholestyramine has been given for 10 days : 4 weeks
  • Investigational agent: 5- fold of the respective plasma half life or 4 weeks, whichever is longer
• Treatment with systemic corticosteroids in a dose higher than 10 mg/day prednisone equivalent
• Change in treatment with nonsteroidal antiinflammatory drugs (NSAIDs) or systemic corticosteroids within the last 4 weeks
• Synovectomy, joint surgery, radio-/chemo synoviorthesis, adrenocorticotropic hormone (ACTH) or any steroid injections (intraarticular, intravenous or intramuscular) within the last 4 weeks
• Participation in another clinical trial within the last 4 weeks
