Environmental Exposure Unit Trial in Subjects With Ragweed-induced Allergic Rhinitis

The purpose of this trial is to see how well an experimental nasal spray, called INI-2004, works for those with allergy symptoms to ragweed. This nasal spray will compare how well 500mcg of INI-2004, given once per week for 4 weeks, works at reducing ragweed allergy symptoms in an Environmental Exposure Unit (EEU), compared to placebo.
