Pharmacodynamics and Pharmacokinetics of Aspirin Inhalation Powder With Non-Enteric-Coated Chewable Aspirin
- Registration Number
- NCT04328883
- Lead Sponsor
- Inova Health Care Services
- Brief Summary
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.
