Further study details as provided by Regeneron Pharmaceuticals:

Primary Outcome Measures:
  • Difference in bronchial allergen challenge (BAC)-induced changes in inflammatory markers in individuals treated with REGN3500, dupilumab and the combination of REGN3500 plus dupilumab or placebo [ Time Frame: Screening (pre-treatment) to week 4 after treatment initiation ]

Secondary Outcome Measures:
  • Incidence of Treatment Emergent Adverse Events (TEAEs) [ Time Frame: Baseline to week 42 ]
  • Severity of TEAEs [ Time Frame: Baseline to week 42 ]
  • Serum concentration-time profile of REGN3500 [ Time Frame: Baseline to week 42 ]
    Assessed by maximum plasma concentration [Cmax]

  • Immunogenicity of REGN3500 and dupilumab combined [ Time Frame: Baseline to week 42 ]
    Assessed by measurement of anti-drug antibodies (ADAs)

Estimated Enrollment: 38
Anticipated Study Start Date: April 2017
Estimated Study Completion Date: August 2018
Estimated Primary Completion Date: August 2018 (Final data collection date for primary outcome measure)
