Details and patient eligibility

About

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.

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
