About this study

Official title: Rituximab (Anti-CD20) for the Treatment of Hepatitis C Associated Cryoglobulinemic Vasculitis

The purpose of this study is to assess the efficacy of Rituximab (anti-CD20) in the treatment of patients with hepatitis C associated cryoglobulinemic vasculitis (HCV-CV) who have failed or are intolerant to interferon-alpha/ribavirin therapy. Up to 75 patients may be screened to enroll 34 adult patients with active HCV-CV in this randomized, non-blinded phase I/II trial. Patients will be randomized to receive either Rituximab 375 mg/M(2) on days 1, 8, 15 and 22 beginning at the time of enrollment or standard therapy. Patients in both groups will be maintained on stable doses of any immunosuppressive therapies that they were receiving at the time of enrollment. Response to Rituximab will be assessed by clinical and laboratory parameters.

Although the cause of cryoglobulinemic vasculitis is not known, a critical component is the presence of cryoglobulins-abnormal proteins that white blood cells called B lymphocytes produce in response to the chronic hepatitis C infection. Rituximab decreases the number of B cells. The Food and Drug Administration approved Rituximab in 1997 for the treatment of B-cell non-Hodgkin's lymphoma.

Patients between 18 and 75 years of age with hepatitis C and signs and symptoms of cryoglobulinemic vasculitis may be eligible for this study. They must have failed, or been unable to tolerate, treatment with IFN-a and ribavirin. Candidates will be screened with a history and physical examination, electrocardiogram (ECG), blood and urine tests, 24-hour urine collection and chest X-ray, if clinically indicated.

Participants will be randomly assigned to receive Rituximab upon entering the study or 6 months after entering the study. Those whose treatment is delayed 6 months will be followed once a month at NIH for disease evaluation and blood tests during that time.

Patients will be given Rituximab intravenously (through a vein) once a week for 4 weeks. For the first dose, patients will be admitted to the hospital for at least 24 hours after the infusion for monitoring. Subsequent infusions will be given on an inpatient or outpatient basis, depending on how the infusion is tolerated. The day before each infusion they will have a history and physical examination, blood work, and other tests, such as X-rays, as clinically indicated.

After the four infusions, patients will be followed for drug side effects and response to treatment. They will have blood tests every week for 4 weeks and will then return to NIH for 1 day every month for 12 months for a physical examination, blood tests, and X-rays, if medically indicated. Visits may be more frequent, if necessary, and patients may be asked to stay longer than a day if test findings requ...

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Rituximab in people with Hepatitis C and Vasculitis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site 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 11 inclusion and 12 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 16 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Yes. Results are posted in the registry (first posted 3 Apr 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percent of Patients in Remission (time frame: month 6). 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 NCT00029107, which also lists 4 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 16 Apr 2012.
