 (submitted: September 22, 2017)
  • Mean evolution of MMP DAI activity score [ Time Frame: Month 24 ]
    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.
  • Mean evolution of MMP DAI activity score [ Time Frame: Month 6 ]
    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.

  • Number of flares / relapses [ Time Frame: Month 24 ]
    relapse / flare is defined as "the reappearance of at least 3 new lesions a month (blisters, erosions) that do not heal within one week, or the extension of established lesions in a patient who has achieved disease control." (Murrell D et al. 2015).

Brief Title  ICMJE Randomized Clinical Trial Comparing the Safety and Efficacy of Rituximab Versus Oral Cyclophosphamide in Severe Forms of Mucous Membrane Pemphigoid
Official Title  ICMJE Randomized Double Blind Double Dummy Control Trial Comparing the Safety and Efficacy of Rituximab Versus Oral Cyclophosphamide in Severe Forms of Mucous Membrane Pemphigoid
Brief Summary

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).

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.
