About this study

Official title: A Randomised Trial of Prednisone and Tamoxifen in Patients With Idiopathic Retroperitoneal Fibrosis

Idiopathic retroperitoneal fibrosis (IRF) is a rare disease characterised by the presence of a retroperitoneal periaortic fibro-inflammatory tissue which may entrap the ureters and cause renal failure. The treatment of IRF is not well established. Corticosteroids are frequently used, but the anti-estrogen agent tamoxifen has also been reported to be effective in a number of reports. However, no randomised trials have been published so far. The aim of the present study is to compare the efficacy of prednisone and tamoxifen in the treatment of IRF.

Read the detailed description

Idiopathic retroperitoneal fibrosis (IRF) is a rare condition hallmarked by the presence of a retroperitoneal mass consisting of chronic inflammatory infiltrate and abundant fibrous tissue. IRF usually presents as a systemic inflammatory disease, with constitutional symptoms (e.g. fatigue, weight loss) and high acute-phase reactants; in addition, IRF patients often complain of abdominal or lumbar pain and, if ureteral involvement is present, they may also show oliguria and symptoms related to uremia.

Ureteral obstructive disease is usually managed by placement of ureteral indwelling stents, nephrostomy tubes or, in the more severe cases, surgical ureterolysis. These approaches are usually followed by medical treatment.

The medical treatment of IRF is largely empirical: corticosteroids are routinely used, but a number of reports have shown that tamoxifen may also be effective. However, no prospective controlled trials have been conducted in patients with this condition. In this study, we compare the efficacy of prednisone and tamoxifen in IRF patients.

Patients who received a diagnosis of IRF will be enrolled, while patients with secondary forms of retroperitoneal fibrosis (e.g. drugs, infections, radiotherapy) will be excluded. When present, ureteral obstruction will be managed by ureteral stents/nephrostomy/ureterolysis. All patients will then receive oral prednisone (1 mg/kg/day) for one month, at the end of which they will be randomized to receive either tamoxifen (0.5 mg/kg/day at fixed dose for 8 months) or prednisone (0.5 mg/kg/day for the first month, 0.25 mg/kg/day for the second and third months, and then tapered off during the ensuing 5 months). A CT/MRI study will be performed before the start of treatment, four months after randomization and at the end of treatment. All patients will be followed up for at least 18 months after the end of treatment.

Disease remission will be defined on the basis of clinical symptoms related to IRF (e.g. pain, constitutional symptoms), levels of acute-phase reactants (erythrocyte sedimentation rate, C-reactive protein), and ureteral obstruction (as assessed by sonography or CT/MRI scan).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tamoxifen and Prednisone in people with Retroperitoneal Fibrosis, run by University of Parma at 1 site in Italy.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 27 Feb 2007. 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 Italy. 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?

Results are not available in the source record.

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?

Difference in recurrence rate at the end of 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 NCT00440349, which also lists 6 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 27 Feb 2007.
