Brief Summary:

The primary objective of the study is to demonstrate that dupilumab is superior to placebo in achieving sustained remission off oral corticosteroids (OCS) in patients with bullous pemphigoid (BP).

The secondary objectives of the study are:

  • To evaluate the OCS-sparing effects of dupilumab in patients with BP
  • To evaluate the effect of dupilumab on itch in patients with BP
  • To evaluate the effects of dupilumab on health-related quality of life measures in patients with BP
  • To evaluate the effect of dupilumab in circulating BP180 and BP230 autoantibody titers
  • To assess the safety and tolerability of dupilumab administered to patients with BP
  • To characterize the trough concentrations of functional dupilumab over time following administration of dupilumab in patients with BP
  • To assess the immunogenicity of dupilumab in patients with BP over time

Primary Outcome Measures :
  1. Proportion of patients achieving sustained remission [ Time Frame: Week 36 ]

Secondary Outcome Measures :
  1. Total cumulative dose of OCS [ Time Frame: Baseline to week 36 ]
  2. Percent change in weekly average of daily peak pruritus numerical rating score (NRS) [ Time Frame: Baseline to week 36 ]
  3. Proportion of patients with improvement (reduction) of weekly average of daily peak pruritus NRS ≥4 [ Time Frame: Baseline to week 36 ]
  4. Percent change in BPDAI activity score [ Time Frame: Baseline to week 36 ]

Other Outcome Measures:

  2. Proportion of patients who do not achieve control of disease activity or who relapse after achieving control of disease activity [ Time Frame: Baseline to week 36 ]
    Note: control of disease activity is defined when new lesions cease to form and existing lesions begin to heal

  5. Change in percent body surface area (BSA) of BP involvement [ Time Frame: Baseline to week 36 ]
  6. Change in BP180 autoantibody (IgG) titers [ Time Frame: Baseline to week 36 ]
  7. Change in BP230 autoantibody (IgG) titers [ Time Frame: Baseline to week 36 ]
  8. Proportion of patients in complete remission and off OCS [ Time Frame: Week 16 ]
  9. Percent change in BPDAI activity score [ Time Frame: Baseline to week 16 ]
  10. Proportion of patients who achieve a reduction in BPDAI activity score of at least 50%, 75%, and 90% [ Time Frame: Baseline to week 16 ]
  11. Percent change in weekly average of daily peak pruritus NRS [ Time Frame: Baseline to week 16 ]
  12. Proportion of patients with improvement (reduction) of weekly average of daily peak pruritus NRS ≥4 [ Time Frame: Baseline to week 16 ]
  13. Incidence of treatment-emergent adverse events (TEAEs) [ Time Frame: Baseline to week 36 ]
  14. Incidence of treatment-emergent serious adverse events (SAEs) [ Time Frame: Baseline to week 36 ]
  15. Incidence of adverse events of special interest (AESIs) [ Time Frame: Baseline to week 36 ]
  16. Incidence of TEAEs [ Time Frame: Baseline to week 48 ]
  17. Incidence of treatment-emergent SAEs [ Time Frame: Baseline to week 48 ]
  18. Incidence of AESIs [ Time Frame: Baseline to week 48 ]
  19. Concentrations of functional dupilumab in serum [ Time Frame: Baseline to week 48 ]
  20. Incidence of treatment-emergent anti-drug antibody (ADA) responses and titer [ Time Frame: Baseline to week 48 ]

Criteria

Key Inclusion Criteria:

  • Patients must have 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 histological and serological confirmation of BP by the baseline visit.
  • 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.

Key Exclusion Criteria:

  • Forms of pemphigoid other than classic BP (eg, mucous membrane-dominant BP, Brunsting-Perry cicatrial 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 2 weeks before the baseline visit
  • Treatment with topical corticosteroids of medium potency or higher, topical calcineurin inhibitor, or topical crisaborole within 1 week 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: 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
