Outcome Measures

Primary Outcomes (1)

  • Combined Symptom and Medication Score (CSMS) in Participants Who Receive a Single Dose of REGN5713-5714-5715 Versus Placebo

    The average CSMS will be calculated based on daily symptom score and daily medication score recorded over the duration of the birch pollen season (BPS). CSMS is calculated by adding the Daily Medication Score (DMS) and Total Symptom Score (TSS) together, with scores ranging between 0 (none) and 38 (severe).

    Until the end of Birch Pollen Season, up to Week 16

Secondary Outcomes (15)

  • Total Symptom Score (TSS), Averaged Over the Duration of the Birch Pollen Season, in Participants Who Receive a Single Dose of REGN5713-5714-5715 Versus Placebo

    Until the end of Birch Pollen Season, up to Week 16

  • Total Nasal Symptom Score (TNSS), Averaged Over the Duration of the Birch Pollen Season, in Participants Who Receive a Single Dose of REGN5713-5714-5715 Versus Placebo

    Until the end of Birch Pollen Season, up to Week 16

  • Total Ocular Symptom Score (TOSS), Averaged Over the Duration of the Birch Pollen Season, in Participants Who Receive a Single Dose of REGN5713-5714-5715 Versus Placebo

    Until the end of Birch Pollen Season, up to Week 16

  • Daily Medication Score (DMS), Averaged Over the Duration of the Birch Pollen Season, in Participants Who Receive a Single Dose of REGN5713-5714-5715 Versus Placebo

    Until the end of Birch Pollen Season, up to Week 16

  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs) Throughout the Study

    Up to Day 127

  • +10 more secondary outcomes

Eligibility Criteria

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

You may qualify if:

  • Documented or participant-reported history of birch pollen-triggered allergic rhinitis symptoms, with or without conjunctivitis, for at least 2 years
  • Positive Skin prick test (SPT) with birch pollen extract in the screening period, as defined in the protocol
  • Positive Allergen-specific IgE (sIgE) tests for birch pollen and Bet v 1 in the screening period, as defined in the protocol
  • Willing and able to comply with clinic visits and study-related procedures

You may not qualify if:

  • Participation in a prior REGN5713-5714-5715 clinical trial
  • Recurrent or chronic rhinitis or sinusitis not associated with birch pollen season, or due to daily contact with other allergens causing symptoms that are expected to coincide with birch pollen season, as assessed by the investigator
  • Participants who anticipate major changes in allergen exposure in their home or work environments that are expected to coincide with the study assessments as assessed by the investigator
  • Persistent chronic or recurring acute infection requiring treatment with antibiotics, antivirals, or antifungals, or any untreated respiratory infections (at the discretion of the investigator) within 4 weeks prior to screening visit. Participants may be re-evaluated for eligibility after symptoms resolve
  • Documentation of active SARS-CoV-2 infection, as defined in the protocol
  • A clinical history of asthma with 2 or more asthma exacerbations requiring hospitalizations or systemic corticosteroids in the previous year
  • History of birch allergy immunotherapy as defined in the protocol
  • Use of anti-IgE or other biological therapy in treatment of asthma or allergy within 6 months prior to screening

Data Sharing

IPD Sharing
Will share

All Individual Patient Data (IPD) that underlie publicly available results will be considered for sharing

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR, ANALYTIC CODE
Time Frame
Individual anonymized participant data will be considered for sharing once the indication has been approved by a regulatory body, if there is legal authority to share the data and there is not a reasonable likelihood of participant re-identification.
Access Criteria
Qualified researchers may request access to anonymized patient level data or aggregate study data when Regeneron has received marketing authorization from major health authorities (e.g., FDA, European Medicines Agency \[EMA\], Pharmaceuticals and Medical Devices Agency \[PMDA\], etc) for the product and indication, has the legal authority to share the data, and has made the study results publicly available (eg, scientific publication, scientific conference, clinical trial registry).
