|---|---|---|---|
| Primary | Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0 | Baseline to Day 28 | Safety and tolerability endpoints will consist of all treatment-related adverse events reporting during the study duration for subjects only from Part 1 of the study. |
| Secondary | Change in Total Nasal Symptom Score (TNSS) After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Total Nasal Symptom Score (TNSS) is the sum of sub-scores for each of nasal congestion, sneezing, nasal itching, and rhinorrhea at each time point, using a four point scale (0-3; 0 = none; 1 = mild; 2 = moderate; 3 = severe), where 0 indicates no symptoms, a score of 1 for mild symptoms that are easily tolerated, 2 for awareness of symptoms which are bothersome but tolerable and 3 is reserved for severe symptoms that are hard to tolerate and interfere with daily activity. TNSS is calculated by adding the sub-score for each of the symptoms to a total out of 12. For TNSS and Area Under the Curve (AUC) analyses, an Analysis of Covariance with treatment and site as factors and Visit 3 (or Visit 2) value as a covariate was used to test for treatment effect at Visit 4. Observed AUC (0-2 Hours) was defined as TNSS from 0 to 120 minutes post Nasal Allergen Challenge (NAC). The Pre-NAC Adjusted AUC (0-2 Hours) was defined as the observed value minus the 0 minutes prior NAC value. |
| Secondary | Subjective Nasal Symptom Scores of Nasal Congestion After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | All measurements were taken 120 minutes Post-Nasal Allergen Challenge (Post-NAC) at Visit 4 and compared to Baseline Visit 3. Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. Nasal congestion was categorized as None, Mild, Moderate, or Severe. |
| Secondary | Subjective Nasal Symptom Scores of Rhinorrhea After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | All measurements were taken 120 minutes Post-Nasal Allergen Challenge (Post-NAC) at Visit 4 and compared to Baseline Visit 3. Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. Rhinorrhea was categorized as None, Mild, Moderate, or Severe. |
| Secondary | Subjective Nasal Symptom Scores of Nasal Itching After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | All measurements were taken 120 minutes Post-Nasal Allergen Challenge (Post-NAC) at Visit 4 and compared to Baseline Visit 3. Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. Nasal itching was categorized as None, Mild, Moderate, or Severe. |
| Secondary | Subjective Nasal Symptom Scores of Sneezing After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | All measurements were taken 120 minutes Post-Nasal Allergen Challenge (Post-NAC) at Visit 4 and compared to Baseline Visit 3. Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. Sneezing was categorized as None, Mild, Moderate, or Severe. |
| Secondary | Nasal Symptom-free Response Rate in Nasal Congestion Scores After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Nasal symptom free response rate was assessed 120 minutes Post-Nasal Allergen Challenge (Post-NAC) to be scored as Yes or No to nasal congestion at Visit 4 (yes indicates subject is free from nasal congestion symptom and no indicates subject still has nasal itching symptom). Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. |
| Secondary | Nasal Symptom-free Response Rate in Rhinorrhea Scores After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Nasal symptom free response rate was assessed 120 minutes Post-Nasal Allergen Challenge (Post-NAC) to be scored as Yes or No to rhinorrhea at Visit 4 (yes indicates subject is free from rhinorrhea symptom and no indicates subject still has nasal itching symptom). Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. |
| Secondary | Nasal Symptom-free Response Rate in Nasal Itching Scores After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Nasal symptom free response rate was assessed 120 minutes Post-Nasal Allergen Challenge (Post-NAC) to be scored as Yes or No to nasal itching at Visit 4 (yes indicates subject is free from nasal itching symptom and no indicates subject still has nasal itching symptom). Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. |
| Secondary | Nasal Symptom-free Response Rate in Sneezing Scores After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Nasal symptom free response rate was assessed 120 minutes Post-Nasal Allergen Challenge (Post-NAC) to be scored as Yes or No to sneezing at Visit 4 (yes indicates subject is free from sneezing symptom and no indicates subject still has nasal itching symptom). Visit 3 was considered Baseline. Visit 2 was considered an alternate Baseline. |
| Secondary | Nasal Symptom-free Response Rate in TNSS After Prophylaxis Treatment | Visit 3 (or alternative baseline at Visit 2) to Visit 4 (14 days prophylaxis treatment). Visit 2 was used as an alternate baseline to report baseline values prior to any nasal allergen challenge (NAC) to minimize any potential priming effects. | Number of subjects that had 25% and 50% reduction in Observed Area Under the Curve (AUC) (0-120 minutes)/Pre-NAC Adjusted AUC (0-120 minutes) at Visit 4 (Day 28) from Visit 2 Observed AUC (0-120 minutes)/Pre-NAC Adjusted AUC (0-120 minutes). For TNSS and Area Under the Curve (AUC) analyses, an Analysis of Covariance with treatment and site as factors and Visit 3 (or Visit 2) value as a covariate was used to test for treatment effect at Visit 4.
