  • In order to qualify to continue to treatment phase, at the end of priming phase (which is 3 hours), Total Symptom Score (TSS) has to be ≥ 7, with nasal congestion score alone ≥ 2 and change in peak nasal inspiratory flow (PNIF) has to be ≥ 15% from pre-prime baseline;
  • Subject is willing to stop use of current decongestant and allergy medications at the start of the washout period prior to priming and during the trial
  • At the discretion of the investigators, subjects may be considered with self-reported mild intermittent asthma (Using <=2 doses of SABA (short-acting beta agonists) per week) or exercise-induced asthma
  • Subject is free of any clinically significant disease that required a physician´s care and/or would interfere with trial evaluations, procedures or participation
  • Subject is able to repeatedly and reliably perform PNIF measurements and must achieve PNIF value of >=60L/min at screening
  • Subject must be capable of reading English and willing to participate in all aspects of the study
