19 Clinical Trials for Various Conditions
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 purpose of this study is to assess the abuse potential of gabapentin enacarbil in healthy adult, non-dependent, recreational drug users.
The main aim is to evaluate the relative abuse potential of soticlestat in healthy adults who has used central nervous system (CNS) depressants for recreational nontherapeutic reasons.
This placebo- and active controlled study will investigate the abuse potential of ACT-541468 in healthy recreational drug users
This randomized, single-dose, placebo- and active-controlled, crossover study will evaluate the abuse liability potential of cenobamate in recreational drug users with sedative drug use experience. In the Qualification phase, subjects will receive a single dose of either alprazolam or placebo in a crossover design, with a wash-out period of at least 24 hours between treatments. Subjects who are clearly able to distinguish the positive control from placebo will be enrolled in the Treatment phase and will be randomized to single oral doses of cenobamate (2 dose levels), alprazolam (2 dose levels), and placebo in a double-blind, double-dummy, 5-way crossover design. Washout-periods between the 5 treatment periods in the Treatment phase will be at least 16 days.
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 randomized, placebo- and active-controlled, crossover study will evaluate the abuse liability potential of RO4917838 in recreational drug users. In a pre-study (Part 1), subjects will receive a single dose of either diazepam or placebo in an inpatient crossover design, with a wash-out period of at least 10 days between treatments. Subjects who are clearly able to distinguish the positive control from placebo will be enrolled in the main study (Part 2) and will be randomized to single oral doses of RO4917838 (3 dose levels), diazepam and placebo in a double-blind, double-dummy inpatient crossover design. Washout-periods between the 5 treatment periods in Part 2 will be at least 10 days.
The purpose of this project is to develop and evaluate an online mentoring and skill-building program for transgender and/or gender minority youth (TGMY) ages 14 to 18, the Teen Connection Project (TCP). The TCP includes seven 90-minute sessions facilitated by transgender and/or gender minority (TGM) adults (who are also mentors). TGMY will be paired with a TGM adult mentor, based on their shared interests. Mentors and mentees will participate together in each session along with other mentors and mentees. Mentors will direct activities and discussion to promote TGMY social-emotional skills. The TCP sessions will include one-on-one mentor-mentee break-out sessions.
This will be a randomized, double-blind, placebo- and active-controlled, 5-way crossover study to evaluate the abuse potential, safety and pharmacokinetics of orally administered PF614 relative to oxycodone IR (immediate-release) tablets and placebo.
The purpose of this study is to examine the abuse potential and pharmacokinetics of PF614 compared with a non-abuse deterrent, commercially available, immediate release (IR) oxycodone hydrochloride (HCl) formulation and placebo.
The purpose of this study is to measure the effects of MDMA on sleep, mood, thinking, and how your body retains water. The researchers are interested in the effects that occur a few hours after taking MDMA as well as effects occurring over the next two days. We will study these effects in a standardized, controlled setting at the Clinical and Translational Science Institute (CTSI) Clinical Research Center (CRC) located at San Francisco General Hospital. The primary hypotheses are: 1. MDMA will induce sleep disruption, as indicated by comprehensive polysomnography, wrist actigraphy, and self-report sleep measures 2. MDMA will alter sodium and water homeostasis by either increasing or blunting the suppression of arginine vasopressin levels and decreasing free water excretion. Effects will be exacerbated by water loading. Secondary hypotheses: 1. Acutely, MDMA will increase both positive and negative arousal, and to increase sociability but not autonomy. 2. Acutely, MDMA will increase risk-taking and willingness to donate money to others in an economic decision making task. 3. MDMA will decrease the stressful effects of talking about a negatively-valenced autobiographical but will increase recall for details for these episodes. 4. MDMA will increase oxidative stress markers and possible ameliorating factors (e.g., ADMA). 5. The short form of the serotonin transported promoter region will be associated with greater acute and discontinuation effects of MDMA.
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).
This will be a randomized, double-blind, double-dummy, placebo- and active-controlled, 6 treatment, 6-period crossover single-dose, Williams square design study in healthy male and/or female adult, non-drug-dependent recreational opioid users.
This is a Phase 4 clinical study in healthy non-drug dependent recreational opioid users to assess the abuse potential of Lyrica when taken alone or in combination with oxycodone.
The growing legalization of cannabis across the U.S. is associated with increases in cannabis use, and accordingly, an increase in the number of individuals with cannabis use problems, including cannabis use disorder (CUD). While there are several medications being investigated as treatment options for CUD, none have been FDA-approved, and there is limited efficacy of traditional behavioral therapy approaches for this population. Consequently, there is a pressing need for the development of new treatments, including approaches that specifically target the brain areas associated with problematic cannabis use behaviors. Elevated attention to drug cues is one of the primary causes of relapse in heavy cannabis users. Preliminary data suggests that transcranial magnetic stimulation (TMS), a non-invasive form of brain stimulation, may be a novel brain-based tool to decrease heightened attention to drug cues in people with CUD. Building on prior data, the primary goal of this study is to evaluate the feasibility and effectiveness of TMS as a tool to decrease attention to drug cues and reduce cannabis use. This study will evaluate whether 2 weeks of rTMS can be used to decrease attentional bias to cannabis cues and reduce cannabis use in heavy cannabis users. We will recruit sixty (60) non-treatment seeking, near-daily cannabis users to receive 10 daily sessions of either real or sham (aka placebo) rTMS over a 2-week period. Participants will live on a residential research unit for 3 weeks. During the residential stay, data on cannabis use (measured using standard human laboratory measures of choice to smoke cannabis) and relevant brain activity (measured using drug cue exposure fMRI tasks) will be collected before and after the course of 10 daily rTMS sessions. We will aim to show whether real rTMS treatment reduces brain response and attentional bias to cannabis cues and reduces cannabis use levels.
