Study of PF614 and Nafamostat for Oxycodone Pharmacokinetics

This study is looking at how your body handles PF614 (an oxycodone prodrug) when it's given alone and with Nafamostat Mesylate. Researchers want to understand how these drugs are absorbed, distributed, and eliminated from your body (pharmacokinetics). They are particularly interested in how Nafamostat affects the release of oxycodone from PF614. You can join if you are a healthy volunteer between 18 and 55 years old. The study aims to measure the maximum amount of the drug in your blood (Cmax) and how long it takes to reach that maximum (Tmax) at different time points over 72 hours. The current recruitment status is unclear.

Study design
This is a single-dose interventional study planning to enroll 54 healthy volunteers.
What's involved
You will receive single doses of PF614 capsules and/or Nafamostat Mesylate. Blood samples will be taken at various times over 72 hours to measure drug levels.
Compensation
Not stated in the trial record.
Follow-up
Your drug levels will be measured for up to 72 hours after receiving the study medication.
