About this study
Official title: Randomized Double Blind Double Dummy Control Trial Comparing the Safety and Efficacy of Rituximab Versus Oral Cyclophosphamide in Severe Forms of Mucous Membrane Pemphigoid
Mucous membrane pemphigoid (MMP) describes a group of chronic auto-immune bullous diseases (AIBD) of the basement membrane zone (BMZ), characterized by predominant or exclusive mucosal involvement, including oral, naso-pharyngeal, laryngo-tracheal, genital, oesophageal, anal and ocular mucous membranes. Circulating autoantibodies are directed against various antigens of the BMZ: BP180, laminin 332 and type 7 collagen. MMP is a rare disease with an incidence of 1.8 new cases/million inhabitants/year in France.
Scar formation which is secondary to initial inflammation, is a characteristic feature of MMP, leading to major disability (e.g blindness and oesophageal, anal, vaginal stenosis) and life-threatening situations (e.g. laryngeal stenosis leading to respiratory failure).
Read more
Dapsone is the first line treatment of mild/moderate forms of MMP. Dapsone is used both as initial treatment, and as maintenance therapy. However, severe forms of MMP can rapidly worsen leading to blindness, aphagia due to esophageal stenosis, respiratory failure due to tracheal or laryngeal stenosis, and urinary and sexual dysfunctions due to genital involvement. These patients are usually treated using immunosuppressive drugs. Indeed, corticosteroids (CS) are not recommended in MMP.
Cyclophosphamide was considered as the most effective immunosuppressant in severe forms of MMP, before the use of rituximab, an anti-CD20 monoclonal antibody (MAb).
Two series from our group have assessed the advantages and disadvantages of IV pulse and oral administration of cyclophosphamide in MMP. Oral administration seems more rapidly effective with 54% of complete remission (CR) after a median time of 24 weeks (16-52 weeks).
The results of 41 patients with severe types of MMP (including a French series of 20 patients) treated with rituximab have been published. Rate of CR after one and two cycles were 66% and 90%, respectively. Clinical improvement was rapid, since a decrease in disease activity was observed after 4 weeks of treatment in 64% of patients.
Our results and those of the literature suggest that rituximab might be more effective than cyclophosphamide, which has been considered as the gold standard of treatment in severe forms of disease, up to now.

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of patients achieving CR or Partial Remission (PR)
Complete remission: absence of any inflammatory lesion, blister or erosion, and, absence of new fibrosing lesions, and/or absence of worsening of established fibrosing lesions Partial remission: presence of transient new inflammatory lesions, blisters or erosions that heal within one week without treatment and, absence of new fibrosing lesions, and/or absence of worsening of established fibrosing lesions. (Murrell D et al. 2015)
Measured: Month 12
Secondary outcomes (6)
Mean evolution of MMP DAI activity score
MMP DAI score is a scoring system who include 2 sub scores: the MMP DAI activity score which assesses disease activity (mucous membrane and skin erosions and blisters), and the MMP DAI damage score, which assesses disease damage (mucous membrane and skin scaring and pigmentation). These 2 "activity" and "damage" sub scores enable distinction between active erosions and blisters from post inflammatory changes and scarring from resolving lesions.
Measured: Month 24
Mean evolution of MMP DAI activity score
MMP DAI score is a scoring system who include 2 sub scores: the MMP DAI activity score which assesses disease activity (mucous membrane and skin erosions and blisters), and the MMP DAI damage score, which assesses disease damage (mucous membrane and skin scaring and pigmentation). These 2 "activity" and "damage" sub scores enable distinction between active erosions and blisters from post inflammatory changes and scarring from resolving lesions.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Mucous membrane pemphigoid (MMP) describes a group of chronic auto-immune bullous diseases (AIBD) of the basement membrane zone (BMZ), characterized by predominant or exclusive mucosal involvement, including oral, naso-pharyngeal, laryngo-tracheal, genital, oesophageal, anal and ocular mucous membranes. Circulating autoantibodies are directed against various antigens of the BMZ: BP180, laminin 332 and type 7 collagen. MMP is a rare disease with an incidence of 1.8 new cases/million inhabitants/year in France.
Scar formation which is secondary to initial inflammation, is a characteristic feature of MMP, leading to major disability (e.g blindness and oesophageal, anal, vaginal stenosis) and life-threatening situations (e.g. laryngeal stenosis leading to respiratory failure).
Dapsone is the first line treatment of mild/moderate forms of MMP. Dapsone is used both as initial treatment, and as maintenance therapy. However, severe forms of MMP can rapidly worsen leading to blindness, aphagia due to esophageal stenosis, respiratory failure due to tracheal or laryngeal stenosis, and urinary and sexual dysfunctions due to genital involvement. These patients are usually treated using immunosuppressive drugs. Indeed, corticosteroids (CS) are not recommended in MMP.
Cyclophosphamide was considered as the most effective immunosuppressant in severe forms of MMP, before the use of rituximab, an anti-CD20 monoclonal antibody (MAb).
Two series from our group have assessed the advantages and disadvantages of IV pulse and oral administration of cyclophosphamide in MMP. Oral administration seems more rapidly effective with 54% of complete remission (CR) after a median time of 24 weeks (16-52 weeks).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Rituximab 1g IV and Cyclophosphamide 50Mg Oral Tablet in people with Severe Forms of Mucous Membrane Pemphigoid, run by University Hospital, Rouen at 27 sites 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 17 inclusion and 40 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: under way, not looking for participants, as of the sponsor's last update on 10 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 27 sites 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. 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?
This study is still under way. Results are not available in the source record yet.
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?
Proportion of patients achieving CR or Partial Remission (PR) (time frame: Month 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 10 Jun 2026.
