What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 54 participants in total. It began in 2024-11-24 with a primary completion date of 2026-12-22.

Brief Summary

A single dose dose study to assess the pharmacokinetics (PK) of oxycodone, when PF614 is administered alone and with nafamostat as an immediate-release (IR) solution and/or extended-release(ER) capsule prototypes.

Positive serum pregnancy test at screening or first admission. Those who are pregnant or lactating will be excluded. 18. Subjects who have received any IMP in a clinical research study within 5 half lives or within 30 days prior to first dose. However, in no event shall the time between last receipt of IMP and first dose be less than 30 days. 19. Subjects who have previously been administered IMP in this study. 20. Subjects who are taking, or have taken, any prescribed or over the counter drug or herbal remedies (other than up to 4 g per day acetaminophen, HRT or hormonal contraception) in the 14 days before study treatment administration (see Section 11.4).
