Study of PF614 Compared to OxyContin® in Healthy Volunteers (SAD)
July 25, 2018 updated by: Ensysce Biosciences
A Phase 1, Single-Center, Dose-Escalation Study to Determine the Safety and Pharmacokinetics of a Single Oral Dose of PF614 in Healthy Subjects Compared to OxyContin®
PF614 is an oxycodone prodrug that is designed for extended-release of oxycodone comparable to OxyContin.
This Single Ascending Dose (SAD) study is designed to assess the safety and pharmacokinetics (PK) of PF614 in comparison to standard doses of OxyContin.

Detailed Description
This will be a Phase 1 randomized, single-center, SAD study in 6 cohorts of 8 healthy male and/or female subjects each (Cohorts 1-6) plus 16 enrolled healthy male and/or female subjects (Cohort 7).
The study will evaluate the safety and PK of PF614 and the PK of oxycodone at doses sufficient to characterize the extent to which plasma oxycodone is produced and maintained following oral ingestion of PF614.
The PK of the prodrug fragments will also be evaluated.
There will be a parallel study arm in each cohort dosed that will use oral OxyContin® as an active comparator.
Subjects will receive PF614 (n=6) or OxyContin as comparator (n=2) orally in the fasted state.
In addition, all subjects starting with Cohort 1C will receive naltrexone at 14 hours pre-dose, 2 hours pre-dose and 10 hours post dose to block the effects of oxycodone.
The starting dose for administration of PF614 will be 15 mg.
The lowest available dose of OxyContin, 10 mg, will be used as the comparator in the first cohort.
PK assessments will be conducted after each cohort to compare the oxycodone area under curve (AUC) of PF614 and OxyContin to determine the most appropriate dose for the subsequent cohorts.
In Cohort 6 (fed subjects), all subjects (n=8) will receive the same PF614 and naltrexone doses as administered in Cohort 5 to evaluate the PK and safety of PF614 in fed vs. fasted state.
Subjects in Cohort 6 will receive a Food and Drug Administration-defined high-fat, high-calorie breakfast 30 minutes prior to study drug administration.
In Cohort 7, treatments will be administered in a cross-over study design across 2 periods.
All subjects (n=16 enrolled; estimated n=12 completers) will receive the same PF614 dose as administered in Cohort 1 (15 mg) with and without naltrexone to evaluate the potential effect of naltrexone on the plasma PK of PF614 and oxycodone.
Cohort 7, Period 1 subjects may return for their cross-over treatments in Period 2 after a minimum of 12 days after receiving their initial Cohort 7 doses.

- Use of prescription medications within 14 days of study drug administration, except for contraceptive medications used by female subjects; use of over-the-counter (OTC) medications within 7 days prior to study drug administration;
- Use of any opioid within 30 days prior to screening;
- Donation of blood within 60 days prior to screening;

- Acute illness (eg, gastrointestinal illness, infection such as influenza, upper respiratory tract infection, or known inflammatory process) within 7 days of dosing
- History of gastrointestinal disturbance requiring frequent use of antacid;
- History of clinically significant gastrointestinal disease and/or surgery which would result in the subject's inability to absorb or metabolize the study drug (eg, gastrectomy, gastric bypass, cholecystectomy);
