Purpose
This is a study to evaluate the efficacy and safety of grass sublingual tablet (SCH697243) versus placebo in the treatment of grass pollen-induced allergic hayfever symptoms. Subjects will receive either the sublingual grass tablet or a placebo tablet during the study. It is expected that those subjects receiving the active sublingual grass tablet will have less hayfever symptoms and need less medications to treat hayfever symptoms during the grass pollen season.

Primary Outcome Measures:
- The combined rhinoconjunctivitis daily symptom score (DSS) and rhinoconjunctivitis daily medication score (DMS) during the grass pollen season (GPS) [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- The average rhinoconjunctivitis DSS during the GPS [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ] [ Designated as safety issue: No ]
- The combined DSS and rhinoconjunctivitis DMS averaged over the peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ] [ Designated as safety issue: No ]
- Rhinoconjunctivitis Quality of Life Questionnaire with Standardized Activities for participants ≥12 years of age (RQLQ12+) during peak GPS [ Time Frame: Peak GPS (expected average duration of 2 weeks) ] [ Designated as safety issue: No ]
- Average rhinoconjunctivitis DMS over entire GPS [ Time Frame: Entire GPS (expected average duration of 5 to 6 weeks) ] [ Designated as safety issue: No ]

Criteria
Inclusion Criteria:
- Must have a clinical history of significant allergic rhinoconjunctivitis to grass (with or without asthma)
- Must have a positive skin prick test response to Phleum pratense (Timothy grass)
- Must be positive for specific immunoglobulin E (IgE) against Phleum pratense (Timothy grass)
- Must have an forced expiratory volume in 1 second (FEV1) of at least 70% of predicted value at Screening
- Safety laboratory tests and vital signs conducted at the Screening Visit must be within normal limits or clinically acceptable to the investigator/sponsor
Exclusion Criteria:
- Has a clinical history of symptomatic seasonal allergic rhinitis and/or asthma due to another allergen during or potentially overlapping the GPS
- Has a clinical history of significant symptomatic perennial allergic rhinitis and/or asthma due to an allergen to which the participant is regularly exposed
- Has received an immunosuppressive treatment within 3 months prior to the Screening Visit
- Has a clinical history of severe asthma
- Has a history of anaphylaxis with cardiorespiratory symptoms
- Has a history of self-injectable epinephrine use
- Has a history of chronic urticaria and angioedema
- Has a clinical history of chronic sinusitis during the 2 years prior to the Screening Visit
- Has current severe atopic dermatitis
- Is breast-feeding, pregnant, or intending to become pregnant
- Had previous treatment by immunotherapy with any grass pollen allergen for more than 1 month within the 5 years prior to the Screening Visit
- Ongoing treatment with any specific immunotherapy at the time of the Screening Visit
- Has a known history of allergy, hypersensitivity or intolerance to the ingredients of the study drug (except for Phleum pratense), rescue medications, or self-injectable epinephrine
- Has any clinically significant condition or situation, other than the condition being studied that, in the opinion of the investigator, would interfere with the study evaluations or optimal participation in the study. Specific examples include but are not limited to hypertension being treated with beta blockers, coronary artery disease, arrhythmia, stroke, ocular conditions requiring topical beta blockers, any condition requiring the use of beta blockers
- Has used any investigational drugs within 30 days of the Screening Visit
- Is participating in any other clinical study
- Is a family member of the investigational study staff conducting this study
- Is unable to meet medication washout requirements
- Is unlikely to be able to complete the trial, for any reason, or likely to travel for extended periods of time during the GPS, which in the opinion of the investigator will compromise the data
- Has a clinically significant abnormal vital sign or laboratory value that would preclude participation in the study
