Outcome Measures

Primary Outcomes (1)

  • Participant Total Combined Symptom (TCS) Score Over the Entire Grass Pollen Season (GPS)

    The TCS is the sum of the rhinoconjunctivitis daily symptom score (DSS) and rhinoconjunctivitis daily medication score (DMS) averaged over the entire GPS. The TCS ranged from 0-54, with increasing score indicating a higher level of symptom severity. The DSS is composed of 6 rhinoconjunctivitis symptoms with scores from 0-18, with increasing score indicating increased severity. The DMS is composed of a sum of the scores associated with rescue medication use per day. The range for the DMS was 0-36, with a lower score indicating less use of rescue medication.

    Start of the GPS to End of the GPS

Secondary Outcomes (3)

  • Participant Average Rhinoconjunctivitis Daily Symptom Score (DSS) Over the Entire GPS

    Start of the GPS to End of the GPS

  • Participant Average Rhinoconjunctivitis Daily Medication Score (DMS) Over the Entire GPS

    Start of the GPS to End of the GPS

  • Participant Average Weekly Rhinoconjunctivitis Quality-of-Life Questionnaire With Standardized Activities (RQLQ(S)) Total Score Over the Entire GPS

You may qualify if:

  • Participants must be 18 to 65 years of age, of either sex, and of any race.
  • Participants must have a clinical history of significant allergic rhinoconjunctivitis to grass (with or without asthma) diagnosed by a physician and have received treatment for their disease during the previous GPS.
  • Participants must have a positive skin prick test response (average wheal diameter \>=5 mm larger than the saline control after 15 to 20 minutes) to Phleum pratense at the Screening Visit.
  • Participants must be positive for specific IgE against Phleum pratense (\>=IgE Class 2) at the Screening Visit.
  • Participants must have an FEV1 \>=70% of predicted value at the Screening Visit.
  • Participants' safety laboratory tests, vital signs and ECG conducted at the Screening Visit must be within normal limits or clinically acceptable to the investigator/sponsor.
  • Participant must be willing to give written informed consent and be able to adhere to dose and visit schedules.
  • Female participants of childbearing potential must be using a medically acceptable and adequate form of birth control. These include:
