The purpose of this study is to assess the abuse potential of gabapentin enacarbil in healthy adult, non-dependent, recreational drug users.
The goal of this study is to compare the abuse potential of low-dose equianalgesic buccal buprenorphine to a commonly used full mu opioid receptor (MOR) agonist in a highly controlled experimental setting. This is a translational study in which healthy participants are phenotyped for psychosocial and Opioid-Use-Disorder-risk-related metrics. In a within-subjects crossover design, 60 participants will receive a standard postoperative oral oxycodone dose (10 mg), placebo, and 3 different doses of buccal buprenorphine across 5 separate sessions. Quantitative Sensory Testing (QST) will be used to evaluate alterations in pain responsiveness relative to placebo across buprenorphine doses and oxycodone, and will compare abuse potential (indexed by the standard FDA drug liking metric) following equianalgesic doses of the two drugs.

Significant public health concerns have arisen from the intravenous misuse of oxymorphone, a potent mu-opioid pain medication. However, little is known about its abuse potential relative to other mu-opioid analgesics. The present study is designed to examine the abuse liability of intravenous oxymorphone compared to other mu opioid agonists (oxycodone, and hydromorphone) among physically dependent opioid abusers.
The purpose of this study is to assess the abuse potential of study drug lasmiditan. Lasmiditan will be compared to a marketed benzodiazepine, alprazolam (positive control), as well as to placebo (dummy substance that looks like lasmiditan or alprazolam without any active drug) to determine the potential for drug abuse. The dosages will be in tablet form and will be taken orally (by mouth). This study will last about 55 days, including screening. Screening will occur within 28 days prior to qualification phase.
The primary objective of this study is to evaluate the abuse potential of intranasal esketamine (112 milligram and 84 mg) compared to racemic intravenous ketamine (0.5 mg/kg) in nondependent, recreational polydrug users of perception-altering drugs.
This study is to evaluate the abuse potential of single-doses of istradefylline compared to placebo and phentermine in recreational stimulant users. Subjects will participate in an outpatient medical Screening visit, a 5-day Qualification (Drug Discrimination) Phase, a 6-period Treatment Phase, and an outpatient safety Follow-Up visit. Study will be approximately 25 weeks total. Within 28 days of the Screening visit, eligible subjects will be admitted to the CRU (Day -1) for the Qualification Phase. During the Qualification Phase, subjects will receive single oral doses of phentermine 60 mg and matching placebo in a randomized, double blind, crossover manner, with each drug administration separated by approximately 48 hours (Day 1 and Day 3), to ensure that they can discriminate and show positive subjective effects of the active controls. Following evaluation of eligibility, subjects may be discharged (those who fail Qualification criteria) or remain in the CRU (those who pass criteria and are eligible) and then proceed directly to the Treatment Phase. The washout interval between last drug administration in the Qualification Phase and first drug administration in the Treatment Phase will be at least 96 hours (4 days). Following confirmation of eligibility from the Qualification Phase, subjects will be randomized to one of 6 treatment sequences according to a 6x6 Williams square. Subjects will receive single oral doses of each of the 6 treatments in a randomized, double-blind, crossover manner, Istradefylline 40 mg, Istradefylline 80 mg, Istradefylline 160 mg, Phentermine 45 mg, Phentermine 90 mg, Placebo. Each drug administration will be separated by at least 21 days. Serial pharmacodynamic evaluations will be conducted up to 24 hours after each study drug administration to confirm exposure to istradefylline.
This single-center study will be a single-dose, randomized, double-blind, placebo- and active-controlled crossover study with a single inpatient treatment visit. The abuse potential of single oral doses of EB-1020 IR (400 mg, 800 mg) will be compared with that of placebo and d-amphetamine (20 mg, 40 mg; active control) in healthy recreational stimulant users. Subjects will participate in a medical Screening visit (Visit 1), one 4-day inpatient Qualification Phase (Visit 2), one 11-day inpatient Treatment Phase (Visit 3), and a safety Follow-up visit (Visit 4).

The primary objective of this study is to compare the relative abuse potential of two different doses of orally administered Acurox Tablets to orally administered immediate-release (IR) oxycodone HCl tablets in non-dependent recreational opioid users.
This research is being done to evaluate if NRP104 is a safe drug. The other purpose is to learn if NRP104 produces a high and any other effects like amphetamine and other stimulant drugs that are abused. This information will give some indication if NRP104 can be abused. NRP104 is an investigational drug. This means that it has not been approved by the U.S. Food and Drug Administration (FDA). Healthy people, between the ages of 18 and 55 with histories of substance abuse that include stimulant drugs, may join. Amphetamines are drugs that are used most often to treat attention deficit hyperactivity disorder (ADHD) in children, to treat narcolepsy (excessive sleepiness) and for weight loss.
Buprenorphine is a medication used to treat opioid addiction, but individuals who use this drug are at risk of abusing it. A buprenorphine and naloxone combination may reduce the likelihood of buprenorphine addiction. This study will evaluate the potential for abuse of buprenorphine and a buprenorphine and naloxone combination in non-dependent opioid users.
