The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

ALK-Abelló A/S
  Purpose
This is a study to evaluate the efficacy and safety of grass sublingual tablet (SCH 697243) versus placebo in the treatment of grass pollen-induced allergic hayfever symptoms. Participants will receive either the sublingual grass tablet or a placebo tablet during the study. It is expected that those participants receiving the active sublingual grass tablet will have less hayfever symptoms and need less medications to treat hayfever symptoms during the grass pollen season.

Condition Intervention Phase
Rhinitis Allergic Conjunctivitis Biological: Grass (Phleum pratense) pollen allergen extract Biological: Placebo for SCH 697243 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicenter, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group Study Evaluating the Efficacy and Safety of Grass (Phleum Pratense) Sublingual Tablet (SCH 697243) in Subjects Between 5 and 65 Years of Age, With a History of Grass Pollen-Induced Rhinoconjunctivitis, With or Without Asthma (Protocol No. P08067)

Primary Outcome Measures:
  • Average Total Combined Rhinoconjunctivitis Daily Symptom Score (DSS) and Rhinoconjunctivitis Daily Medication Score (DMS) Over the Entire Grass Pollen Season (GPS) [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ]

    The total combined score was the sum of the rhinoconjunctivitis DSS and rhinoconjunctivitis DMS for the entire GPS (total score range: 0 to 54), with a lower score representing less rhinoconjunctivitis symptoms and use of medications.

    For rhinoconjunctivitis DSS, participants assessed a total of 6 rhinoconjunctivitis symptoms (runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, and watery eyes) each on a scale of 0 to 3 (0=no symptoms, 1=mild symptoms, 2=moderate symptoms, 3=severe symptoms; score range: 0 to 18), with a lower score representing less rhinoconjunctivitis symptoms.

    For rhinoconjunctivitis DMS, participants reported their use of specific rescue medications with specific scores assigned to each medication (score range: 0 to 36), with a lower score representing less use of medications for rhinoconjunctivitis.



Secondary Outcome Measures:
  • Average Rhinoconjunctivitis DSS Over the Entire GPS [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ]
    For rhinoconjunctivitis DSS, participants assessed a total of 6 rhinoconjunctivitis symptoms (runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, and watery eyes) each on a scale of 0 to 3 (0=no symptoms, 1=mild symptoms, 2=moderate symptoms, 3=severe symptoms; score range: 0 to 18), with a lower score representing less rhinoconjunctivitis symptoms.

  • Average Total Combined Rhinoconjunctivitis DSS and Rhinoconjunctivitis DMS Over the Peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ]

    The total combined score was the sum of the rhinoconjunctivitis DSS and rhinoconjunctivitis DMS for the entire GPS (total score range: 0 to 54), with a lower score representing less rhinoconjunctivitis symptoms and use of medications.

    For rhinoconjunctivitis DSS, participants assessed a total of 6 rhinoconjunctivitis symptoms (runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, and watery eyes) each on a scale of 0 to 3 (0=no symptoms, 1=mild symptoms, 2=moderate symptoms, 3=severe symptoms; score range: 0 to 18), with a lower score representing less rhinoconjunctivitis symptoms.

    For rhinoconjunctivitis DMS, participants reported their use of specific rescue medications with specific scores assigned to each medication (score range: 0 to 36), with a lower score representing less use of medications for rhinoconjunctivitis.


  • Average Rhinoconjunctivitis Quality of Life Questionnaire With Standardized Activities for Participants ≥12 Years of Age (RQLQ12+) Over the Peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ]
    The RQLQ12+ consists of 7 domains: Activities, Sleep, Non-Nose/Eye Symptoms, Practical Problems, Nasal Symptoms, Eye Symptoms, Emotional. Participants reflect on their experience over the previous 7 days and assess 28 items on a scale of 0 to 6 (0=Not troubled, 6=Extremely troubled; score range: 0-6 [mean of all domain scores]), with a higher score indicating more significant impairment due to seasonal allergic rhinoconjunctivitis.

  • Average Rhinoconjunctivitis DMS Over the Entire GPS [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ]
    For rhinoconjunctivitis DMS, participants reported their use of specific rescue medications with specific scores assigned to each medication (score range: 0 to 36), with a lower score representing less use of medications for rhinoconjunctivitis.

  • Average Rhinoconjunctivitis DSS Over the Peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ]
    For rhinoconjunctivitis DSS, participants assessed a total of 6 rhinoconjunctivitis symptoms (runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, and watery eyes) each on a scale of 0 to 3 (0=no symptoms, 1=mild symptoms, 2=moderate symptoms, 3=severe symptoms; score range: 0 to 18), with a lower score representing less rhinoconjunctivitis symptoms.

  • Average Rhinoconjunctivitis DMS Over the Peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ]
    For rhinoconjunctivitis DMS, participants reported their use of specific rescue medications with specific scores assigned to each medication (score range: 0 to 36), with a lower score representing less use of medications for rhinoconjunctivitis.

  • Average Paediatric Standardised Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) Overall Score Over the Peak GPS (Participants 6 to <12 Years of Age) [ Time Frame: Peak GPS (expected average duration of 2 weeks) ]
    For PRQLQ, participants assessed a total of 19 items within 5 domains: Nose Symptoms, Eye Symptoms, Practical Problems, Activity Limitation and Other Symptoms, each on a scale of 0 to 6 (0=Not troubled, 6=Extremely troubled; score range: 0 to 6 [mean of all domain scores]), with a higher score indicating more significant impairment due to seasonal allergic rhinoconjunctivitis.
