• For Part 2, subjects with a well-documented history of seasonal allergic rhinitis (specifically ragweed pollen) with documentation of sensitivity by positive skin testing and/or IgE testing to the relevant allergens 12 months prior to enrollment that correlate with clinical history.
• For Part 2, a ragweed positive skin prick test with a wheal diameter at least 5 mm larger than the negative control and/or a ragweed specific IgE greater or equal to 0.7 kU/L.
• For Part 2, subjects with confounding allergies, or sensitization to cat epithelia, dog epithelia, Dermatophagoides farinae, or Dermatophagoides pteronyssinus or prevalent and relevant seasonal allergens as per the skin prick test may be included if sensitization is not clinically relevant (ie. subject is non-symptomatic and/or can avoid the allergen during the study) at the discretion of the Investigator.
• For Part 2, subjects with a baseline TNSS ≤ 3/12 at Visit 3 and a minimum qualifying TNSS score of a change of 6/12 from their baseline score after NAC #1 on at least 2 diary cards.
• For Part 2, subjects' average post diluents nasal congestion score must be < 1 at admission for each study visit.

You may not qualify if…

• Female of childbearing potential not using adequate contraceptive measures.

• Systemic corticosteroid or other immunosuppressive medications use in the previous three months or during the protocol.*

• Subjects with any significant clinical abnormalities which may interfere with study participation.
• Prior use of AO+ Mist.
• Subjects with immunodeficiencies, nasal lesions, nasal polyps, or sinus infections.
• Use of an investigational drug within 30 days before screening Visit 1. * Exclusionary criterion due to 1) medication use as marker of persistent comorbid allergic or inflammatory condition that may increase subject risk with study participation, 2) potential of medication to interfere with study outcome measures or results.
