Exclusion Criteria

1.Nasal symptoms: SNOT-22 score <20 as assessed at screening. 2.Prior polyp surgery: Subjects who have undergone any nasal surgery (excluding polypectomy performed as an outpatient procedure) within 4 months before screening or have had =4 sinonasal surgeries in the past. 3.Comorbidities: Presence of a known pre-existing clinically important condition including: active tuberculosis, pulmonary fibrosis, bronchopulmonary aspergillosis, eosinophilic granulomatous polyangiitis (Churg-Strauss syndrome), Young's syndrome, Kartagener's syndrome or dyskinetic ciliary syndromes, and cystic fibrosis.Clinically significant endocrine, autoimmune, metabolic, neurological, renal (calculated creatinine clearance <60 mL/min), gastrointestinal, hepatic, cardiovascular, hematological, or any other system abnormalities that are uncontrolled with standard treatment. 4.Malignancy: A current malignancy or previous history of cancer in remission for less than 5 years prior to screening (subjects will not be excluded if they had localized carcinoma of the skin that was resected for cure). 5.Liver Disease: Known pre-existing liver disorders (ie, non-alcoholic fatty liver disease (NALFD) or Gilbert's syndrome),or unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices or persistent jaundice), cirrhosis, or known biliary abnormalities. 6.Prior anti-inflammatory treatment: Subjects who have required a burst of systemic corticosteroids (eg, oral, intravenous, intramuscular corticosteroids) within the 1 month before screening or are scheduled to receive systemic corticosteroids during the study period for another condition, or who have required intranasal corticosteroid drops within 1 month prior to screening.
7.Intolerant to mometasone furoate nasal spray. 8.Specific conditions/concomitant diseases: Subjects with conditions such as: antrochoanal polyps, nasal septal deviation that would occlude at least one nostril; acute sinusitis, invasive fungal rhinosinusitis, neutrophilic polyposis, nasal infection or upper respiratory infection at screening or in the 2 weeks before screening. Subjects requiring chronic systemic antibiotic treatment for rhinosinusitis. 9.Ongoing rhinitis medicamentosa. 10.ECG Assessment: Subjects with QTcF =450 msec for males or QTcF =470 msec for females on the Screening visit ECG. However, if QTcF is above this prespecified limit and there are no other clinically significant ECG abnormalities in the opinion of the Investigator, the assessment can be repeated in triplicate. The triplicate QTcF values should be averaged by the Investigator to determine eligibility of the subject to enter the Run-in period. However, if any of the triplicate ECGs show a clinically significant abnormality in the opinion of the Investigator, the subject should be excluded, regardless of the average QTcF of the triplicates. 11.Alcohol/Marijuana/Illicit Drugs/Substance Abuse: A known or suspected history of alcohol misuse, marijuana, illicit drugs, or substance abuse within 12 months prior to Screening visit. 12.Smoking history: Asthma or COPD patients that are current smokers (any substance), or former smokers with a smoking history of =10 pack-years [(number of cigarettes per day/20) × number of years smoked]. A former smoker is defined as a subject who quit smoking at least 6 months prior to Screening visit. This includes electronic cigarettes and vaping. 13.Immunodeficiency: A
