- Patients who are on intranasal corticosteroids (INCS) spray unless they have received stable dose for at least 4 weeks prior to Visit 1.
- Patients who have undergone sinus intranasal surgery (including polypectomy) within 6 months prior to Visit 1.
- Patients who have taken:
- Biologic therapy/systemic immunosuppressant to treat inflammatory disease or autoimmune disease within 5 half-lives prior to Visit 1
