NCT04206553

Brief Summary

The main purpose of this study is to investigate whether dupilumab is effective and safe for the treatment of bullous pemphigoid. Dupilumab is a type of drug called a "monoclonal antibody". An antibody is a special kind of protein that the immune (defense) system normally makes to fight bacteria and viruses. Bullous pemphigoid is an autoimmune subepidermal blistering disease, predominately affecting the elderly (typical onset after age 60). The study is looking at several other research questions, including:

  • Side effects that may be experienced by people taking dupilumab
  • How dupilumab works in the body and affects the body
  • How dupilumab affects quality of life
  • How much dupilumab is present in the blood
  • To see if dupilumab works to wean the patient off oral corticosteroids

Outcome Measures

Primary Outcomes (1)

  • Percent of Participants Achieving Sustained Remission at Week 36

    Sustained remission at week 36, defined as: (1) Complete remission (absence of new lesions \& epithelialization of old lesions) \& off oral corticosteroids (OCS) no later than week 16 \& (2) Absence of disease relapse (appearance of ≥3 new lesions a month \[blisters, eczematous lesions, or urticarial plaques\] or at least 1 large eczematous lesion or urticarial plaque that does not heal within 1 week) after completion of OCS taper, no later than week 16, to week 36 \& (3) Absence of need for rescue therapy during 36 weeks (rescue therapy includes increase of OCS dose during the taper, re-initiation of OCS after completion of the OCS taper, or initiation of any BP-directed therapy). Participants with missing sustained remission data at week 36 due to discontinuation due to lack of efficacy, treatment-related AE, or death were considered non-responders \& those with missing data due to other reasons were handled using multiple imputation.

    At Week 36

Secondary Outcomes (47)

  • Total Cumulative Dose of Oral Corticosteroids (OCS) From Baseline to Week 36

    Week 36

  • Percent Change in Weekly Average of Daily Peak Pruritus Numerical Rating Scale (NRS) Score From Baseline to Week 36

    Baseline, Week 36

  • Percent of Participants With Improvement (Reduction) of Weekly Average of Daily Peak Pruritus NRS ≥4 From Baseline to Week 36

    Baseline, Week 36

  • Percent Change in Bullous Pemphigoid Disease Area Index (BPDAI) Activity Score From Baseline to Week 36

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must have characteristic clinical features of bullous pemphigoid (BP) (eg, urticarial or eczematous or erythematous plaques, bullae, pruritus) at the screening and baseline visits.
  • Study participants are required to have a confirmed diagnosis of BP based on histopathology, immunopathology, and serology at the baseline visit, as defined in the protocol.
  • Bullous Pemphigoid Disease Area Index (BPDAI) activity score ≥24 at baseline and screening visits.
  • Baseline peak pruritus NRS score for maximum itch intensity ≥4
  • Karnofsky performance status score ≥50% at the screening visit.

You may not qualify if:

  • Forms of pemphigoid other than classic BP (eg, Brunsting-Perry cicatricial pemphigoid, anti-p200 pemphigoid, epidermolysis bullosa acquisita, or BP with concomitant pemphigus vulgaris)
  • Patients who are receiving treatments known to cause or exacerbate BP (eg, angiotensin converting enzyme inhibitors, penicillamine, furosemide, phenacetin, dipeptidyl peptidase 4 inhibitor) who have not been on a stable dose of these medications for at least 4 weeks prior to the screening visit
  • Have ever received treatment with an IL-4 or IL-13 antagonist such as dupilumab, tralokinumab, or lebrikizumab.
  • Treatment with systemic corticosteroids within 7 days before the baseline visit
  • Treatment with topical corticosteroids of medium potency or higher, topical calcineurin inhibitor, or topical crisaborole within 7 days before the baseline visit
  • Treatment with non-steroidal immunosuppressive/immunomodulating drug(s) (eg, mycophenolate mofetil, azathioprine, or methotrexate) within 4 weeks before the baseline visit.
  • Treatment with BP-directed biologics as follows:
  • Any cell-depleting agents including but not limited to rituximab: within 12 months before the baseline visit, or until lymphocyte and CD 19+ lymphocyte count returns to normal, whichever is longer
  • Other biologics (such as IL-5 inhibitors benralizumab or mepolizumab): within 5 half-lives (if known) or 16 weeks prior to the baseline visit, whichever is longer
  • Intravenous immunoglobulin within 16 weeks prior to the baseline visit
