About this study

Official title: Evaluation of Rituximab-based Regimen Compared to Conventional Therapeutic Strategy For Remission Induction In Patients With Newly-Diagnosed or Relapsing Eosinophilic Granulomatosis With Polyangiitis. Prospective, Randomized, Controlled, Double-blind Study

Phase III, comparative, multicenter, randomized, controlled, double-blind and superiority research, comparing rituximab-based regimen with conventional therapeutic strategy for the induction of remission in patients with eosinophilic granulomatosis with polyangiitis (EGPA).

Patients with newly diagnosed or relapsing EGPA will be randomized in a 1:1 ratio to receive:

  • Experimental therapeutic strategy based on the use of rituximab (experimental group)
  • Conventional therapeutic strategy based on Five-Factor Score (FFS)-assessed disease severity (comparative group)
Read the detailed description

Systemic vasculitides are inflammatory diseases of blood vessels, among which anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are often severe with life-threatening manifestations or complications. AAV include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA, formerly Churg-Strauss syndrome).

Cytotoxic drugs and glucocorticoids have been the standard of care for remission induction for nearly five decades. This regimen improved the outcome of severe AAV from death to a strong likelihood of disease control and temporary remission. However, a remission is not obtained in all patients with this combination of drugs, and most patients experience disease flares requiring repeated treatment with associated significant morbidity and mortality.

In 2 prospective controlled trials, rituximab, an anti-CD20 monoclonal antibody, was shown to be non inferior to cyclophosphamide to induce remission with an acceptable safety profile in patients with systemic GPA and MPA. However, patients with EGPA were not included in these trials and rituximab has not been evaluated prospectively to induce remission in this disease which pathogenesis is complex and not only restricted to ANCA responsibility.

In patients with EGPA, overall survival is good when treatment is stratified according to prognostic factors (Five Factor Score) but long-term outcome is not so good since relapses occur in more than 40% of patients, leading to high cumulative morbidity and damage. In small retrospective studies, rituximab seems promising as a remission-induction agent in patients with EGPA, independently from the ANCA status.

The trial detailed here is the first prospective trial evaluating rituximab as induction-remission treatment for EGPA.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Rituximab and Cyclophosphamide in people with Eosinophilic Granulomatosis With Polyangiitis (EGPA), run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 5 inclusion and 16 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 15 Jan 2026. 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 France. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The percentage of patients who obtained a BVAS=0 and prednisone dose ≤7.5 mg/day at day 180. (time frame: 180 days). 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 NCT02807103, which also lists 1 linked publication.

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 15 Jan 2026.
