Primary | TNSS Area Under Curve (AUC) Post Nasal Allergen Challenge (NAC) Over the First Hour After the Challenge (0-1 Hour (hr): A Comparison between the Grazax® +Dupixent® and the Grazax® Placebo +Dupixent® Placebo Treatment Arms | NAC (TNSS Area-under-Curve [AUC 0-1hr]), comparing the TNSS AUC 0-1 hr between the referenced treatment arms: a clinical tolerance outcome measure.
The Total Nasal Symptom Score (TNSS) is a participant-reported composite symptom assessment of 4 symptoms (rhinorrhea, nasal congestion, nasal itching and sneezing), each scored on a scale from 0 to 3 where 0 = none, 3 = severe. TNSS total score is calculated as the sum of the response for all 4 individual nasal symptom scores and can range from a minimum score of 0 to a maximum score of 12: a higher score indicates more severe symptoms. |
0 to 1 hour of the NAC at Year 3, One Year After Completion of Treatment | |
Secondary | TNSS Area Under Curve (AUC) Post Nasal Allergen Challenge (NAC) Over the First Hour After the Challenge (0-1 Hour (hr): A Comparison between the Grazax® +Dupixent® and Grazax® + Dupixent® Placebo Treatment Arms | NAC (TNSS Area-under-Curve [AUC 0-1hr]), comparing the TNSS AUC 0-1 hr between the referenced treatment arms: a clinical tolerance outcome measure.

Secondary | Peak Nasal Inspiratory Flow (PNIF) (Delta PNIF Area Under the Curve [AUC] 0-1 hr): A Comparison Between Treatment Arms | The following analyses will performed as an assessment of clinical tolerance:
Comparison between Grazax® +Dupixent® and Grazax® Placebo +Dupixent® Placebo treatment arms, and Comparison between Grazax® +Dupixent® and the Grazax® + Dupixent® Placebo treatment arms PNIF is defined as the speed of inspiration of air in Liters per minute when breathing into the lungs through the nose. Lower scores indicate less ability to breathe air into the lungs due to more severe nasal symptoms. |

This assessment is a desensitization to grass pollen outcome measure. |

Secondary | Frequency, Severity, and Relatedness of Adverse Events (AEs) byTreatment Arm | The number, severity, and relatedness of local and systemic AEs and Serious AEs will be summarized by treatment arm. AEs will be classified by grade according to the National Cancer Institute's (NCI's) Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0, November 27, 2017).

Week 0 to Year 3 | |
Secondary | Weekly Seasonal Symptoms Score (Visual analogue scale [VAS] 0-10 cms): A Comparison Between the Grazax® +Dupixent® and Grazax® Placebo +Dupixent® Placebo Treatment Arms | A participant-reported (self-administered) seasonal symptoms outcome measure on a Likert scale (0 to 10 cms, 0=No Symptoms, 10=Worst possible symptoms), a quality of life measure reflecting the quality of life impact of rhinitis ("hay fever") symptoms experienced during the span of the "last week." | Year 3 | |
Secondary | Weekly Rhinitis Quality of Life Scores Using the Juniper Mini-Rhinoconjunctivitis Quality of Life Questionnaire: A Comparison Between the Grazax® +Dupixent® and Grazax® Placebo +Dupixent® Placebo Treatment Arms | The Juniper Mini-Rhinoconjunctivitis Quality of Life Questionnaire [MiniRQLQ], is a participant-reported (self-administered) questionnaire that consists of 14 questions grouped into 5 domains. Each question is scored on a scale of 0 (not troubled with symptoms) to 6 (extremely troubled with symptoms) and describes nose/eye symptoms experienced "during the last week." | Year 3 | |
Secondary | Global Rhinitis Evaluation Scores: A Comparison Between the Grazax® +Dupixent® and Grazax® Placebo +Dupixent® Placebo Treatment Arms | Participants are asked, as part of their Year 3 visit, to describe their allergic rhinitis ("hay fever"). This administered set of questions is comprised of 6 questions, focusing on nasal and eye symptoms [0=No symptoms, 3=Severe] and a single question regarding the change in current rhinitis/hay fever compared to the years prior to initiating study treatment (Much better:+3, Much worse: -3).
