简要总结
To assess the superiority of rituximab compared to cyclophosphamide used in combination therapy with dapsone, to achieve CR or partial remission (PR) (corresponding in clinical practice to "almost Complete Remission") of disease activity at Month 12, in patients with severe forms of MMP

入选标准
- •Male or female patients aged ≥18 years old and ≤ 85 years old with a newly diagnosed or previously diagnosed severe MMP diagnosed according to the International MMP Consensus (Chan 2002) on the following criteria: Clinical features: Blisters or erosions predominantly affecting any or all mucous membranes (oral, nasal, pharyngeal, laryngeal, anal, genital, or esophageal,) with or without clinically observable scarring. Ocular involvement includes conjunctival inflammation, shortening of fornices, symblepharon, ankyloblepharon, entropion, trichiasis and corneal neovascularisation. Patients with skin involvement must not have more than 2 out of the 4 clinical criteria for bullous pemphigoid (BP) proposed by the French group (Vaillant L et al,1998; Joly P et al. 2004) Direct Immunofluorescence (DIF): Linear deposits of IgG, IgA and/or C3 on the BMZ by DIF of patient's skin or mucous membrane NB: Patients with pure ocular involvement can be included despite a negative DIF performed on the oral mucosa and despite the absence of suggestive histological picture if ophtalmologists consider the clinical ocular features are typical of MMP and that performing a biopsy on an inflammatory conjunctiva is risky. Histology: Sub epithelial blister with or without significant leukocyte infiltrate by standard histology of skin or mucosal lesions, when the skin or mucosal biopsy is possible and appropriate.
- •MMP is defined as "severe" in patients with: Sight-threatening ocular disease, and/or Potentially life-threatening laryngeal, tracheal or oesophageal stenosis, and/or Involvement of a mucosal site where there is a risk of scarring stenosis (larynx, trachea, esophagus, anus, foreskin, vagina…) and/or DocuSign Envelope ID: 50295166-4E99-49C6-987F-578D0A3FC8AE XML File Identifier: aaTJ0TmguGQxRA0B9cisw43tfaI= Page 15/39 More than one mucosal site involved and/or Mucosal involvement (including exclusive but severe oral involvement defined as an oral MMP DAI score > 10), and/or Skin or oral involvement, which have not achieved control of disease activity despite a one month treatment with dapsone at the maximum dose tolerated or by salazopyrine in patents intolerant to dapsone or having a contra indication to dapsone. or for patients with sightthreatening ocular disease, and/or potentially life-threatening laryngeal, tracheal or oesophageal stenosis, without previous treatment by dapsone
- •Patient having read and understood the information letter and signed the Informed Consent Form
- •Patient with updated vaccinations. It is recommended that a patient's vaccination record and the need for immunization prior to study entry be carefully investigated.
- •For women who are not postmenopausal (≥12 months of non− therapy-induced amenorrhoea) or surgically sterile (absence of ovaries and/or uterus) and who do not plan on having children anymore: agreement to remain abstinent or use two adequate methods of contraception, including at least one method with a failure rate of <1% per year, during the treatment period and for at least 12 months after the last dose of study treatment. Abstinence is acceptable only if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception. Barrier methods must always be supplemented with the use of a spermicide. For men: Surgical sterility or agreement to remain abstinent or use a condom during the treatment period and for at least 12 months after the last dose of study treatment and agreement to refrain from donating sperm during this same period. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
