| CSMS (Combined Symptom and Medication Score) Averaged Over the Peak Grass Pollen Season (GPS) | The daily CSMS is calculated as the sum of the daily Symptom Score (dSS) and the daily Medication Score (dMS). The dSS component of the CSMS is calculated as the sum of 6 individual symptom (2 conjunctival and 4 nasal) scores, each with a range of 0 to 3 points and divided by 6, and therefore has a total range between 0 and 3. The dMS is a score assigned according to the step of relief medication used in a day (from 0: no relief medication to 3: oral corticosteroids with step and step 2 medications). The daily CSMS has a range between 0 and 6. The average CSMS over the peak GPS will be calculated as sum of the daily CSMS within the peak GPS divided by the number of days of the peak GPS where the CSMS has been collected. Higher values in the scale represent worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |

| Measures collected approximately over 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |
| Total Combined Score (TCS) Averaged Over the Peak GPS | The daily TCS was the sum of the dSS and dMS calculated from the data recorded in the eDiary. For the dSS 6 individual symptoms were assessed: conjunctival symptoms (2 items) and nasal symptoms (4 items). Each item was scored on a 4-point severity scale (0 = no symptoms, 3 = severe symptoms). The dSS was calculated as the sum of the scores for the 6 indicidual symptoms, ranging from 0 to 18. For the dMS was rated on a scale from 0 to 20, depending on the relief medication use. Higher scores in TCS are related to worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |
| TCS Averaged Over Entire (or Truncated) GPS | The daily TCS was the sum of the dSS and dMS calculated from the data recorded in the eDiary. For the dSS 6 individual symptoms were assessed: conjunctival symptoms (2 items) and nasal symptoms (4 items). Each item was scored on a 4-point severity scale (0 = no symptoms, 3 = severe symptoms). The dSS was calculated as the sum of the scores for the 6 indicidual symptoms, ranging from 0 to 18. The dMS was rated on a scale from 0 to 20, depending on the relief medication use: Score = 0, No relief medication used = 0 up to Score 20 = use of oral corticosteroids. Higher scores in TCS are related to worse outcomes. | Measures collected approximately over 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |
| Daily Symptom Score (dSS) of the CSMS Averaged Over the Peak and Entire (or Truncated) GPS | The dSS component of the CSMS was calculated as the sum of 6 individual symptom (2 conjunctival and 4 nasal) scores, each with a range of 0 to 3 points and divided by 6, and therefore has a total range between 0 and 3. Higher scores are related to worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection). |
| Daily Medication Score (dMS) of the CSMS Averaged Over the Peak and Entire (or Truncated) GPS | dMS of the CSMS consists on a score with a range from 0 to 3: Score 0 (no relief medication) to 3 (highest step relief medication) per day; based on at least 1 dose of the medication of the highest step taken that day. Higher scores are related to worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection). |
| dSS of the TCS Averaged Over the Peak GPS and Entire (or Truncated) GPS | The dSS of the TCS is calculated as the sum of the scores (0-No symptoms to 3-Severe symptoms) for the 6 individual symptoms (i.e. ranging from 0 to 18). Higher scores are related to worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection) |
| dMS of the TCS Averaged Over the Peak GPS and Entire (or Truncated) GPS | The dMS of the TCS was rated on a scale from 0 to 20 depending on the use of relief medication: Score = 0, No relief medication used = 0 up to Score 20 = use of oral corticosteroids. Higher values are related to worse outcomes. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection) |
| Correlation Between TSS During CPT, CSMS, TCS, dSS (for CSMS and TCS) and dMS (for CSMS and TCS) Over the Peak and Entire (or Truncated) GPS for Subjects With a Positive CPT at Baseline. | Variables evaluated for correlation:
The correlation between the above variables were explored using linear regression models. Outcomes are presented as Mean Squared Errors, representing the strength of the correlation, CI numbers not available. Low values represent stronger correlation between the two variables. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection) |
| Number of Well Days and Severe Days During the Peak and Entire (or Truncated) GPS. | A "well day" was defined based on CSMS as a day with:
The probability of a well day or a severe day was analyzed using data on a by-day level per subject using generalized estimating equation (GEE) or similar approaches as appropriate. Well days and severe days were assessed during the peak GPS and entire (or truncated) GPS. | Measures collected approximately over 2-5 weeks (peak GPS) or 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection) |
| Serum Ig Responses (Change in Total IgE and Grass-specific IgE From Baseline to Visit 12 and Visit 15) | Immunological measurements (total IgE and grass-specific IgE) and their changes between screening and post-treatment were analyzed descriptively. The change from baseline in immunoglobulin measurements was additionally analyzed using analysis of covariance (ANCOVA), including treatment groups and with baseline as covariate. | Baseline (Visit 2), Visit 12 (2 weeks before start of the GPS) and visit 15 (end of the GPS). The exact time frame depended on the GPS start and end dates for each region, and visit 15 was usually in the range between 24 and 32 weeks after screening |
| Change in Serum Ig Responses (Change in Grass-specific IgG4 From Baseline to Visit 12 and Visit 15) | Immunological measurements (grass-specific IgG4) and their changes between screening and post-treatment were analyzed descriptively. The change from baseline in immunoglobulin measurements was additionally analyzed using analysis of covariance (ANCOVA), including treatment groups and with baseline as covariate. | Baseline (Visit 2), Visit 12 (2 weeks before start of the GPS) and visit 15 (end of the GPS). The exact time frame depended on the GPS start and end dates for each region, and visit 15 was usually in the range between 24 and 32 weeks after screening |
| RQLQ(S) During the Peak GPS | Rhinoconjunctivitis quality of life was assessed using the Rhinoconjunctivitis Quality of Life Questionnaire with Standardised Activities (RQLQ[S]). The RQLQ(S) comprises 28 questions in 7 domains (activity limitation, sleep problems, nose symptoms, eye symptoms, non-nose/eye symptoms, practical problems, and emotional function). Each question is scored on a scale from 0 to 6. Score is calculated as a mean of the 28 responses, with a range from 0 to 6. Higher scores are related with worse outcomes. | Measures were collected approximately over 2-5 weeks (peak GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |
| Frequency, Severity and Relationship of AEs to Treatment | Number of subjects with at least one event of the specified AE type. The frequency, relationship and severity of AEs will be assessed within each treatment group. Note: TEAE (treatment emergent adverse events) are reported in the Adverse Event section. | Up to 1 year |

Only in subjects with past or current asthma, PEFR was performed at Visits 2 (baseline) to 11, prior to and approximately 30 to 60 minutes following study drug administration. At Visit 1 (screening), the PEFR should be ≥75% predicted for subjects to be eligible for the study. Note that the exact time frame for each visit depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. | At baseline (Visit [V]2) only for all subjects, and also at V3 (V2 +~1 week [wk]), V4 (V3+~1wk), V5 (V4+~4wk), V6 (V5+~3wk), V7 (V6+~1wk), V8 (V7+~1wk), V9 (V8+~1wk), V10 (V9+~1wk) and V11 (~3-7wk before GPS) for subjects with past or current asthma |

| Secondary | CSMS Averaged Over the Entire (or Truncated) GPS | The daily CSMS is calculated as the sum of the daily Symptom Score (dSS) and the daily Medication Score (dMS). The dSS component of the CSMS is calculated as the sum of 6 individual symptom (2 conjunctival and 4 nasal) scores, each with a range of 0 to 3 points and divided by 6, and therefore has a total range between 0 and 3. The dMS is a score assigned according to the step of relief medication used in a day (from 0: no relief medication to 3: oral corticosteroids with step and step 2 medications). The daily CSMS has a range between 0 and 6. The average CSMS over the entire (or truncated) GPS will be calculated as sum of the daily CSMS within the peak GPS divided by the number of days of the GPS where the CSMS has been collected. Higher values in the scale represent worse outcomes. | FAS | Posted | Least Squares Mean | Standard Error | score on a scale | Measures collected approximately over 10 weeks (entire/truncated GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |

|
|
| Secondary | Total Combined Score (TCS) Averaged Over the Peak GPS | The daily TCS was the sum of the dSS and dMS calculated from the data recorded in the eDiary. For the dSS 6 individual symptoms were assessed: conjunctival symptoms (2 items) and nasal symptoms (4 items). Each item was scored on a 4-point severity scale (0 = no symptoms, 3 = severe symptoms). The dSS was calculated as the sum of the scores for the 6 indicidual symptoms, ranging from 0 to 18. For the dMS was rated on a scale from 0 to 20, depending on the relief medication use. Higher scores in TCS are related to worse outcomes. | FAS | Posted | Least Squares Mean | Standard Error | score on a scale | Measures collected approximately over 2-5 weeks (peak GPS). The exact time frame depended on the GPS start and end dates for each region (depending on pollen detection), therefore, a specific week from baseline can not be estimated globally. |
