Status Completed

Clinical Trial Summary

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.

Clinical Trial 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. ;
