Detailed Description
This is a Prospective, Controlled, Double Blinded, Single Center, Randomized, 3 Arm, Parallel Assignment, Phase 1b/2a Study to assess the safety, tolerability, and preliminary efficacy of B244 delivered as an intranasal spray in healthy volunteers and subjects with seasonal allergic rhinitis. This will be a 2-part study. In Part 1, safety and tolerability will be evaluated during 14 days of study treatment twice-a-day followed by 4 weeks of follow-up in healthy volunteers. In Part 2, preliminary efficacy will be evaluated in subjects with a history of seasonal allergic rhinitis outside of the local pollen season.
For Part 1 (safety and tolerability evaluation in healthy volunteers) we will enroll 24 subjects. Safety and tolerability will be assessed by reporting of AEs, physical examination and vital signs (blood pressure, heart rate, respiratory rate) during 14 days of treatment and up to 28 days of follow-up.
An internal safety committee meeting will review the 2 week Part 1 safety data and, if there are no safety concerns, the study will proceed to Part 2 to evaluate preliminary efficacy in subjects with a history of seasonal allergic rhinitis (SAR)
For Part 2 (preliminary efficacy evaluation in subjects with a history of SAR to ragweed pollen) will enroll 42 subjects. Safety and tolerability will be assessed in subjects with allergic rhinitis by reporting of AEs, physical examination and vital signs (blood pressure, heart rate, respiratory rate) during 14 days of treatment.
For Part 2, study will be paused for safety review using the same stopping criteria as in Part 1.
Rescue medications will not be allowed during the study.

Measure Description |
Time Frame |
---|---|---|
Change in Total Nasal Symptom Score (TNSS) After Prophylaxis Treatment
Time Frame: 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. |
