Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be a randomized, double-blind, placebo-and active-controlled, 3-way crossover study to evaluate the abuse potential and pharmacokinetics of intranasally administered PF614, relative to crushed oxycodone HCl IR tablets and placebo in non-dependent recreational opioid users. The study will consist of 4 phases: Screening, Qualification, Treatment, and Follow-up.

CROSSOVER

This will be a 3 way crossover study to evaluate the abuse potential of PF614.

Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors

Double blind treatment and randomization will be used to reduce potential bias during data collection and evaluation of clinical endpoints. A placebo control will be used to establish the frequency and magnitude of changes in clinical endpoints that may occur in the absence of active treatment, as well as to minimize subject and investigator bias.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Males or females, aged 18 to 55 years, inclusive, in good general health.
2. Body mass index (BMI) within the range of 18.0 to 33.0 kg/m2, inclusive, and a minimum weight of 50.0 kg.
3. Current opioid users who have used opioids for recreational (non-therapeutic) purposes (i.e., for psychoactive effects) at least 10 times in the past year and at least once in the 12 weeks before Screening.
4. Must have experience with intranasal opioids for the purpose of recreational (non-therapeutic) use on at least 3 occasions in the year prior to Screening.
5. Must not be physically dependent on opioids, as demonstrated by successful completion of the Naloxone Challenge Test.
6. Must meet Drug Discrimination Test eligibility criteria (Section 8.3).
7. Female subjects must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at randomization. Post-menopausal women (i.e., no menstrual period for at least one year) must have a follicle-stimulation hormone (FSH) level \>30 milli-international unit (mIU)/mL at Screening.
8. Female subjects must use a medically acceptable method of birth control (oral or transdermal contraceptives, condom, spermicidal foam, intrauterine device (IUD), progestin implant or injection, heterosexual abstinence, vaginal ring or sterilization of partner) from the time of Screening through 2 weeks after the last study treatment.
9. Male subjects must agree to use medically acceptable methods of contraception (diaphragm/sponge/condom with spermicide, vasectomy), and/or their female sexual partners of childbearing potential must be using and willing to continue to use medically acceptable contraception (i.e., hormonal oral contraceptive pills, patches, or vaginal rings, contraceptive implant or injection intrauterine contraceptive system \[with or without hormone\]) from Screening and for at least 90 days after the last study drug administration.
10. Able to speak, read and understand English sufficiently to allow completion of all study assessments.
11. Subjects must be able to provide meaningful written informed consent.
12. Subjects must be willing and able to follow study instructions and be likely to complete all study requirements.

Exclusion Criteria

2. History or presence of clinically significant abnormality as assessed by physical examination, medical history, electrocardiograms (ECGs), vital signs or laboratory values, which, in the opinion of the investigator, would jeopardize the safety of the subject or the validity of the study results. Retesting may be permitted at the discretion of the investigator.
3. History or presence of acute respiratory depression, chronic pulmonary disease, cor pulmonale, delirium tremens, central nervous system (CNS) depression, or increased cerebrospinal or intracranial pressure.

9. Female subjects who are currently pregnant (have a positive pregnancy test) or lactating or who are planning to become pregnant within 30 days of last study drug administration.
10. Positive for hepatitis B surface antigen (HBsAg), hepatitis C, human immunodeficiency virus (HIV) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
11. Evidence of clinically significant hepatic or renal impairment, including alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>1.5 × the upper limit of normal (ULN). Retesting may be permitted at the discretion of the investigator.

16. Falls under any other condition, that, in the investigator's opinion, (i) puts the subject at increased risk, (ii) could confound the study results, (iii) may interfere significantly with the subject's participation in the study, or (iv) has the potential to limit the subject's ability to complete the study.
