Trial 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. Read more about this study

About this study

Official title: Open Label Multicenter Induction of CII Tolerance in Patients With Rheumatoid Arthritis

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.

Read the detailed description

RA is an inflammatory disease that causes pain, swelling, stiffness, and loss of function in the joints. The study will evaluate the effects of using oral bovine CII on RA patients by assessing the levels of inflammation markers such as interferon gamma (IFN-gamma), interleukin-10 (IL-10), and transforming growth factor beta (TGF-beta). This study is a multicenter clinical trial to be conducted at the University of Tennessee, Memphis (the lead center) and the West Tennessee Medical Specialty Clinic (a collaborating site).

Patients enrolled will be allowed to continue a constant dose of disease-modifying anti-rheumatic drugs (DMARDs) and prednisone less than or equal to 7.5 mg/day. Patients will be randomly assigned to one of two groups. The low dose group will receive 30 mcg daily for 10 weeks, then 50 mcg daily for 10 weeks, followed by 70 mcg daily for 10 more weeks; the high dose group will receive 90 mcg daily for 10 weeks, then 100 mcg daily for 10 weeks, followed by 130 mcg daily for 10 more weeks. Blood will be collected at screening and at Weeks 10, 20, and 30. Blood will be analyzed for indicators of inflammation.

Note: this trial is no longer being conducted as an intervention trial. Accrual has been discontinued, although patients previously enrolled are still being followed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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%.

    Measured: Before and after each 10-week treatment

Secondary outcomes (1)
  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.

    Measured: Before and after each 10-week treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Oral bovine type II collagen in people with Rheumatoid Arthritis, run by University of Tennessee at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 May 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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%. (time frame: Before and after each 10-week treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000401, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2013.
