14. Allergy, hypersensitivity, or contraindication to corticosteroids, steroids, or to any excipients in OPN-375

15. Exposure to any glucocorticoid treatment with potential for systemic effects (e.g., oral, parenteral, intra-articular, or epidural steroids, high dose topical steroids) within 1 month before Visit 1 (Day 1/Baseline); except as noted in inclusion criteria for subjects with comorbid asthma or COPD
