Brief Summary
Rheumatoid arthritis (RA) is an autoimmune disease characterized by swelling and inflammation of the joints. In RA, the immune system attacks a person's own cells inside joints, eventually leading to joint damage and disability. This study will determine if oral bovine type II collagen (bovine CII) will lead to decreased joint inflammation in RA patients.

Outcome Measures
Primary Outcomes (1)
Repeated measures analysis of variance with contrasts to determine if the change in the PBMC-IFN gamma-alpha 1(II)/PBS stimulation index is significantly at the 0.05 level and/or greater than or equal to 30%.
Before and after each 10-week treatment
Secondary Outcomes (1)
A Pearson correlation coefficient will be calculated for the change in the PBMC-INF gamma-alpha1(II)/PBS stimulation index and the change in the reactivity to RA CII epitope alpha 1 (II) CB11 for each dose.
Before and after each 10-week treatment
Study Arms (2)
1
EXPERIMENTALThe low dose group will receive CII 30 mcg daily for 10 weeks, then 50 mcg daily for 10 weeks, followed by 70 mcg daily for 10 more weeks.
2
EXPERIMENTALThe high dose group will receive CII 90 mcg daily for 10 weeks, then 100 mcg daily for 10 weeks, followed by 130 mcg daily for 10 more weeks.
Interventions
Drug can be interrupted or stopped for suspected adverse events.
Eligibility Criteria
You may qualify if:
- Clinically stable RA and unlikely to require adjustment of doses of DMARDs, NSAIDs, prednisone, or anti-TNFα therapies for the treatment phase of the study
- Meets American College of Rheumatology (ACR) 1988 revised criteria for RA
- Onset of disease at age 16 or older
- Onset of disease at least 3 months prior to enrollment
- PBMC - IFNγ - α1(II)/PBS stimulation index greater than or equal to 1.5 in 6 months prior to baseline visit
- Agree to discontinue herbal remedies described in this protocol
- Agree to use acceptable forms of contraception
You may not qualify if:
- Participation in another clinical research study involving the evaluation of another investigational drug within 90 days prior to study entry
- Currently taking greater than 7.5 mg prednisone daily
- Intra-articular corticosteroid injections within 30 days prior to study entry
- Concurrent serious medical condition which, in the opinion of the investigator, makes the patient inappropriate for the study
- Pregnancy
- Beef allergy
- Use of fish oil within 4 weeks of study entry
- Previous use of auranofin or cyclophosphamide (all other DMARDs are allowed)
- Previous autologous or heterologous stem cell transplantation
- Active malignancy or past treatment consisting of antineoplastic drugs or total lymphoid irradiation
- Intolerance to citrus juices or colorless carbonated beverages
