Outcome Measures

Primary Outcomes (1)

  • Proportion of patients reached disease control

    Disease control was defined as the point at which new lesions or pruritic symptoms cease to form and existing lesions start to heal.

    within 4 weeks

Secondary Outcomes (9)

  • Complete remission rate

    within 64 weeks

  • Relapse rate

    within 64 weeks

  • Adverse events

    within 64 weeks

  • Changes in BPDAI scores

    from 0 to 64 weeks

  • Changes in itching NRS scores

    from 0 to 64 weeks

  • +4 more secondary outcomes

Interventions

Duplimab was administered according to the guidelines of the atopic dermatitis treatment regimen, which involved the first dose of 600 mg followed by 300 mg every two weeks. Because of comorbidities or the side effects of corticosteroid, some patients used dupilumab in the initial course of treatment, while others added dupilumab when the traditional drugs proved ineffective. The discontinuation was a joint decision between treating dermatologists and patients. Concomitant medicine was decided by clinicians, depending on the assessing of disease status and patients' choices, and reduced according to international guidelines.

Study Population

Adult bullous pemphigoid patients treated with dupilumab between January 1, 2021, and July 31, 2022, at six leading dermatology departments in the Chinese Collaborative Network for Autoimmune Bullous Diseases.

You may qualify if:

  • Adult bullous pemphigoid patients treated with dupilumab between January 1, 2021, and July 31, 2022, at six leading dermatology departments in the Chinese Collaborative Network for Autoimmune Bullous Diseases.
  • The diagnosis of BP requires clinical manifestations and immunological or pathological evidences.
  • Dupilumab treatment should continue for at least 4 weeks and possibly longer.

You may not qualify if:

  • Drug-induced BP, γ-1 pemphigoid
  • Patients with less than 4 weeks of follow-up
