Official Title: Establishment of a FeNO Cutoff Value for Evaluating the Response to Budesonide-formoterol in Patients With Chronic Cough Suggestive of Cough Variant Asthma: a Multicenter Prospective Clinical Study
Brief Summary:
This is a multicenter, prospective, single-arm, interventional clinical study to predict the response to budesonide-formoterol treatment in patients with chronic dry or nocturnal cough by determining a cut off value of FeNO.In this study, the response to ICS/LABA treatment is defined as reduction in cough VAS score from baseline of ?30 mm after 8 weeks of ICS/LABA treatment.Subjects will be treated with Symbicort® 160/4.5 mcg, 1 puff, BID for 8 weeks with 4 study visits: Visit 1 (Day 0), Visit 2…
