once-daily doses (50, 200, and 400 µg) of S0597 intranasal spray compared with placebo in participants with SAR who were exposed to ragweed pollen challenges in an environmental exposure unit (EEU). Study Design: This was a phase 2, randomized, double-blind, placebo-controlled, single-center, 4-arm,
parallel study conducted in the EEU at Kingston General Hospital, Kingston, Ontario, Canada, between October 2 and December 17, 2014. Adults with documented SAR during ragweed pollen season were exposed to controlled levels of ragweed pollen in the EEU. The study was given ethical clearance by the Queen's University Health Sciences and Affiliated Teaching Hospitals Research Ethics Board. The ClinicalTrials.gov identifier is NCT01940146.
Inclusion criteria: Adult participants (18–65 y) were required to have a minimum 2-year history of SAR
due to ragweed pollen, a positive skin prick test to short ragweed (defined as a wheal ≥3 mm larger than the negative control) within 12 months prior to enrollment, a total nasal symptom score (TNSS) of at least 6 at least once during a 1- to 3-hour screening/priming challenge in the EEU and within the first 2 hours of the Figure 3.

Participants attended a 3-hour baseline pollen challenge on day 1. Allergen challenge was performed again on days 7 and 14. At the day 1 visit, the site dispensed study medication for the 13 days of treatment along with rescue medication and participants were instructed to record study medication administration time, any missed doses, and any use of rescue medication in a take-home diary. Participants were randomized to This randomized, double-blind, parallel-group, single-center study assessed the dose-related efficacy and safety of 3 doses of either S0597 at doses of 50, 200, or 400 µg/day, or placebo as a nasal spray to be administered once daily in S0597, a novel INS, in participants with SAR who were challenged with ragweed pollen in an EEU. the evening on days 1 to 13.

The consistent response, with statistically significant improvements in all of the nasal symptoms compared with placebo on days severity of each component symptom was scored from 0 to 3 and the total scores were calculated by adding the scores for each symptom (Table 1).
