Mycophenolate Mofetil for Treatment of Relapses of Wegener's Disease or Microscopic Polyangiitis (MPA)

August 23, 2024 updated by: University Medical Center Groningen

Comparative Study of the Efficacy of Induction Therapy With Cyclophosphamide or Mycophenolate Mofetil for Non-life-threatening Relapses of PR3- or MPO-ANCA Associated Vasculitis

The purpose of this study is to determine the efficacy and safety of a new drug, mycophenolate mofetil, for the treatment of relapses of ANCA-associated vasculitis (Wegener's granulomatosis or microscopic polyangiitis). Therefore, we compare the standard therapy with cyclophosphamide to mycophenolate mofetil.

The investigators expect mycophenolate mofetil to be less toxic and almost equally effective as cyclophosphamide.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Treatment of ANCA-associated vasculitis consists of two phases: remission induction with highly effective, but also relatively toxic drugs, and, secondly, after remission is achieved, maintenance therapy with less toxic drugs. The standard induction therapy of a relapse of Wegener's granulomatosis or microscopic polyangiitis consists of the combination of cyclophosphamide and prednisolone. Although this induction therapy is very effective, it is very toxic as well.

Searching for an alternative for cyclophosphamide, we will test the efficacy and safety of a new combination therapy with mycophenolate mofetil and prednisolone. We will compare the effect and safety of the standard induction therapy with the new therapy. When relapses occur, patients will be randomized for either the standard therapy with cyclophosphamide or for mycophenolate mofetil.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
