Pharmacodynamics and Pharmacokinetics of Aspirin Inhalation Powder With Non-Enteric-Coated Chewable Aspirin

Completed · Phase 1

Conditions studied: Platelet Aggregation Inhibitors

In brief

ASA inhalation powder is an inhaled nonsteroidal anti-inflammatory drug-device combination that has been developed to reduce the risk of vascular mortality in patients with suspected acute myocardial infarction (MI), an FDA approved indication for oral formulations of aspirin. The primary goal of study OTP-P0-926 is to collect pharmacokinetic (PK)and pharmacodynamics (PD) pilot data to determine onset and extent of aspirin response after administration of varying doses of inhaled ASA (50-100mg) and 162 mg Non-Enteric-Coated Chewable ASA. PD will be assessed using standard methods to measure platelet inhibition by aspirin including platelet aggregation, serum thromboxane,and urinary thromboxane. Furthermore, the pharmacokinetics (PK) of ASA will be determined and compared to PD measurements. Results of this pilot study will guide dosing in a subsequent larger Phase II study.

• Presence of braces, partials or dentures.
• Clinically significant abnormal laboratory parameters.
• Antiplatelet agents (ASA, NSAID's, P2Y12 inhibitors, etc.) within 10 days of dosing visit.
• HIV, hepatitis B or C infection.
• Presence of clinically significant cardiovascular, pulmonary, hepatic, renal, endocrinological, hematological, immunologic, metabolic, neurological, or gastrointestinal disease.
• Clinically significant physical examination.
• History of hypersensitivity or allergy to aspirin.
