The purpose of this phase 2 study is to assess the safety and efficacy of oral ifetroban for
the treatment of aspirin-exacerbated respiratory disease (AERD). AERD is a disease that
involves asthma, recurring nasal polyps, and respiratory reactions to aspirin and other
nonsteroidal anti-inflammatory drugs.

- Stable asthma (post-bronchodilator FEV1 of ≥ 60%, no glucocorticoid burst for at least two weeks prior to starting treatment, no hospitalizations or emergency room visits for asthma at least three months prior to starting treatment and not on a dose >1000 µg fluticasone or equivalent daily).
- ≥ 18 years of age
- Exhibit symptomatic AERD within two weeks of starting treatment by demonstrating a score of at least 20 on the Sino-nasal Outcome Test (SNOT) - 22.
Exclusion Criteria:
- Current smoking, defined as daily tobacco smoking in the last six months and at least one instance of tobacco smoking in the last three months.

- Use of oral or systemic steroids (e.g. prednisone or equivalent) > 20 mg daily in the last four weeks before starting treatment.
- Daily use of long-acting antihistamines, 5-lipoxygenase inhibitors (e.g. zileuton) and leukotriene receptor antagonists (e.g. montelukast) in the last two weeks before starting treatment.
- Less than 12 months of allergy shots (maintenance dose of allergy shots are allowed if treatment duration exceeds 12 months).
- Any use of nonsteroidal anti-inflammatory drugs (NSAIDs) or any drug that inhibits the cyclooxygenase enzyme in the last two weeks before starting treatment.
- History of bleeding diathesis or use of anticoagulant or antiplatelet drugs in the last two weeks before starting treatment.
- Any immunosuppressive treatment including but not limited to methotrexate, cyclosporine, mycophenolate, tacrolimus, gold, penicillamine, sulfasalazine, hydroxychloroquine, azathioprine, cyclophosphamide, and immunotherapy in the last two weeks before starting treatment (maintenance dose of allergy shots are allowed if treatment duration exceeds 12 months).
- Endoscopic sinus surgery / polypectomy within the past three months
- Previously treated in a clinical trial with ifetroban within the past three months.
- Previously treated with other investigational drugs within eight weeks or five half-lives, whichever is longer, before screening
- Conditions/concomitant disease which make them unevaluable for the efficacy endpoints
This is a randomized, placebo-controlled, double-blind phase 2 trial evaluating approximately 76 subjects with symptomatic AERD on the safety and efficacy of 8 weeks of oral ifetroban treatment. Eligible AERD subjects will be randomized to receive 8 weeks of either oral ifetroban daily or matching placebo followed by a 2-week post-treatment period.
