89 Clinical Trials for Various Conditions
1. The major aims are to assess: (1) the relationship of basal and alcohol-induced neurosteroid and GABA levels to the degree of acute alcohol intoxication in healthy male and female volunteers; and (2) the effect of acute pregnenolone administration on the degree of acute alcohol intoxication in these same volunteers. Specific hypotheses are: * Baseline serum levels of pregnenolone, pregnenolone sulfate (PS), dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEA-S) will be inversely correlated with the magnitude of acute behavioral responses to alcohol (sedation, anxiolysis, amnesia, psychomotor impairment and intoxication). That is, higher baseline levels of these neurosteroids will be associated with lessened behavioral responses to alcohol. * Baseline serum levels of allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), androstanediol, androsterone and GABA will be directly correlated with the magnitude of acute behavioral responses to alcohol. That is, higher baseline levels of these substances will be associated with heightened behavioral responses to alcohol. * Acute alcohol ingestion, compared to placebo ingestion, will increase serum levels of allopregnanolone and THDOC and plasma levels of GABA and will decrease plasma levels of PS. (Effects on levels of other neurosteroids are not specifically predicted based on animal data but will be examined in an exploratory manner.) * Acute alcohol-induced increases in serum levels of allopregnanolone and THDOC and in plasma levels of GABA will be directly correlated with the magnitude of acute behavioral responses to alcohol. Acute alcohol-induced decreases in serum levels of PS will be directly correlated with the magnitude of acute behavioral responses to alcohol. Correlations between alcohol-induced changes in other neurosteroids and changes in behavior are not specifically predicted but will be examined in an exploratory manner. * Pregnenolone, compared to placebo, pre-treatment will antagonize the acute effects of alcohol on the behavioral measures.
This will be a (2 visit) double-blind, randomized, placebo crossover design clinical study to assess the potential benefits of FSD-F2R6-A-CP versus a placebo by assessing its impact on side effect profiles as well as cognitive abilities, motor abilities, and breath alcohol concentration following ingestion of alcohol followed by the dietary supplement or placebo. This study will enroll healthy men and women.
This is a randomized, parallel-group study designed to explore the differences between cannabis intoxication, alcohol intoxication and co-intoxication involving both alcohol and cannabis, utilizing electroencephalography (EEG) as well as more traditional intoxication measures such as breath alcohol concentration and balance metrics. If eligible for the study, participants will be randomized to complete one study session in our mobile laboratory, during which they will use either alcohol, cannabis (which will be self-administered, ad libitum) or both alcohol and cannabis.
Alcohol intoxication is responsible for a large proportion of violent crime/assault and personal injury in our society. While a number of variables have been associated with alcohol-related aggression, high trait aggression and impaired executive function have been identified as key factors. Both Alcohol Use Disorder (AUD) and Impulsive Aggression behavior (AGG) are related to impaired social-emotional information processing (SEIP) whereby social threat cues, especially ones that are ambiguous in nature, lead to hostile attribution and negative emotional response to the "other" and, then, aggression against the "other". Thus, understanding the underlying neuroscience of SEIP under the influence of alcohol will be critical to identifying targets for intervention to reduce alcohol-related aggressive behavior. In addition to potential pharmacologic and cognitive-behavioral based interventions, such interventions may also involve the rehabilitation of aberrant neuronal circuits underlying social cognitive function through neuroplasticity-based remediation exercises. This study is designed to see how brain activation of cortico-limbic circuits involving social-emotional information processing, analyzed by fMRI Imaging, are impacted by alcohol administration in those with and without aggressive disorders and with and without alcohol use disorder.
The main objectives of this study were to test if 2 different doses of Cannabidiol (compared to placebo) alter 1) breath alcohol concentration, 2) craving and subjective responses to alcohol or 3) cognitive performance following a standard dose of alcohol.
This is a Phase 2 single-blind, randomized, multicenter study to compare the efficacy and safety of a single dose of TNX-1300 to placebo with usual care in patients with acute cocaine intoxication within the emergency department setting.
This observational study is being conducted to determine plasma concentrations of tetrahydrocannabinol (THC) and its metabolites, 11-OH-THC and THC-COOH, in plasma of subjects who visit the emergency department due to acute cannabinoid intoxication.
The goal of this experimental study is to examine the effect of alcohol, gender, and bystander attitudes on bystander barriers and sexual violence intervention among young adult men and women (age 21-20). The main questions it aims to answer are: * Does alcohol intoxication and gender influence bystander barriers and sexual violence intervention? * Does alcohol intoxication have a greater impact on bystander barriers and sexual violence intervention among men, compared to women? * Does alcohol intoxication have a greater impact on bystander barriers and sexual violence intervention among those with higher, compared to lower, prosocial bystander attitudes? Participants will be randomly assigned to one of two beverage conditions (alcohol or control beverage) and those assigned to alcohol will complete the study on either the ascending or descending alcohol limb. Participants will project themselves into a heat-of-the moment, risky sexual violence scenario that will assess bystander barriers and behavioral intentions. Researchers will compare those assigned to the alcohol and control beverage condition and men/women to see if this impacts bystander barriers and sexual violence intervention.
This study aims to test the efficacy of experiential-based training to increase DUI offenders' perceptions or risk associated with alcohol use.
An Open-Label, Randomized Pilot Study Comparing the Safety of a Single Dose of TNX-1300 to Usual Care (UC) Alone for the Treatment of Signs and Symptoms of Acute Cocaine Intoxication in Male Emergency Department (ED) Subjects
This study is a prospective, controlled study in healthy volunteers all of whom are residents, medical students, faculty physicians, or emergency department nursing and ancillary staff.
The purpose of this study is to determine the accuracy of an impairment algorithm based on eye tracking while watching a short film clip, in comparison to a clinical reference standard of impairment.
Background: People who binge drink are more likely to have risky sexual encounters, and alcohol changes brain activity associated with reward decisions related to those behaviors. Researchers want to better understand how alcohol s effects on risky sexual behavior that might lead people to contract sexually transmitted diseases (STDs) like HIV, the virus that causes AIDS. Objective: To study how alcohol impacts decisions about engaging in risky sex. Eligibility: Healthy adults ages 21-65 without alcohol use disorder Design: Participants will have 2 study visits, 1 month apart. They will arrive and depart via taxi. They will consume alcohol at 1 visit, chosen at random. At visit 1, participants will answer questions about HIV knowledge, HIV risk behaviors, and sexual interests. They will view pictures of clothed people and pick those they might have sex with. They will think about the person s risk of having an STD and whether they would use a condom during sex. At both visits, participants will sit in a bar-like room and have 2 drinks that may contain alcohol. Then they will have magnetic resonance imaging (MRI) brain scans. For this, they will lie on a table that slides in and out of a metal tube. The scanner makes loud noises; they will get earplugs. They will complete tasks that include looking at pictures and making choices about money. At the beginning of both visits the participants will be screened with urine drug test and pregnancy test. Duiring each visit the participants breath alcohol will be measured, and they will discuss whether they feel intoxicated. Participants will get snacks and stay at the clinic for up to 6 hours after the MRIs.
This study aims to develop a phone app to assess gait differences at different levels of alcohol intoxication.
This study will test the hypothesis that a BAC (blood alcohol content) of 0.1% will not significantly alter the anti-hypoglycemic effect of mico-dose glucagon in individuals with type 1 diabetes.
The primary goal of the study is to assess the residual effects of heavy drinking on academic performance. The investigators will also explore whether these effects differ by family history of alcohol abuse and hangover symptoms, as well as compare males and females with respect to these effects. The primary hypothesis is that intoxication (0.10 g% blood alcohol concentration \[BAC\]) with an alcoholic beverage impairs next-day academic performance, as measured by scores on quizzes, standardized academic achievement tests, and standardized neurobehavioral assessments. The secondary hypothesis is that family-history-positive individuals will show a greater performance decrement the day after heavy drinking than family-history-negative individuals.
This study will assess effects of tetrahydrocannabinol (THC) and THC + alcohol in marijuana users on prefrontal brain activity, using functional near-infrared spectroscopy (fNIRS) during resting state and during memory task performance. Participants will complete fNIRS testing 120 minutes following THC or identical placebo (Phase 2A), or THC/ethanol, THC/placebo ethanol, placebo THC/ethanol, and placebo THC/placebo ethanol (Phase 2B), and oxygenated hemoglobin (HbO) concentration will be measured.
This study will test the reliability of a procedure for self-administering ethanol (alcohol) intravenously (through a vein), using a computer-assisted method. People ordinarily self-administer alcohol through drinking alcoholic beverages, but blood alcohol levels resulting from drinking vary greatly among individuals. For research on alcohol dependence and treatment, a tool for achieving precise blood levels is needed. In addition to testing this method of alcohol administration, the study will examine self-administration behavior and resulting breath alcohol concentration, the effects of alcohol on the participants, and differences between men and women in alcohol self-administration. Healthy normal volunteers between 21 and 45 years of age may be eligible for this study. Participants are assigned to one of two study groups. Group 1 undergoes three 7-hour study sessions and group 2 participates in two sessions, each of which includes the following procedures: * Breathalyzer and urine tests for alcohol and illicit drug use. * Urine pregnancy test for women. * Light lunch. * Questionnaire about health and recent drinking. Alcohol infusion: Subjects are seated in a comfortable chair and instructed on how to use a computer to give themselves a short infusion of alcohol through a catheter (plastic tube) that has been inserted into a vein in their the arm. Sensors are placed on their chest to monitor heart beat and their neck to record skin blood flow. At the start of the session, subjects complete questionnaires about any drug effects and urges to drink they may be feeling. They are trained on how to use the computer to administer alcohol and are then allowed to self-administer alcohol through the catheter any time they like, as long as their peak breath alcohol level does not exceed 0.1 g% (a level that would result from ingestion of 4 to 6 drinks in most people). If that point is reached, the computer automatically inactivates self-administration until the level is lowered again. Breathalyzer readings are taken every 15 to 30 minutes. Subjects may read, watch television or videos or listen to music during the sessions. Recovery: At the end of the 2.5 hours of self-administration, the catheter is removed and subjects can eat, read, watch television and relax in the clinic until their breath alcohol level falls below 0.02 g%, usually after 2.5 to 3 hours, when they can go home by taxi or with a pre-arranged designated driver.
Intimate Partner Sexual Violence (IPSV) is a significant and understudied public health problem among sexual minority (SM) and heterosexual couples, yet little is known about factors that contribute to IPSV perpetration. This proposal aims to determine the acute effect of alcohol and sexual communication on IPSV. In this study, 240 couples (50% SM) who drink alcohol will be recruited from the Metro-Denver area. Upon arrival to the laboratory, a trained research assistant will check the participant's ID, verify that they adhered to the pre-session guidelines, administer a breath test to ensure a breath alcohol content (BrAC) of 0.00 and conduct a field sobriety test. They will also obtain informed consent for each member of the couple separately. Female participants will take a pregnancy test to ensure a negative result. All participants will complete measures to reverify eligibility criteria and be weighed to determine their correct alcohol dose. Partners will separately complete a baseline survey measuring demographic factors, alcohol use, sexual communication, and daily experiences. After completing the survey, participants will be assigned a beverage condition (alcohol or no-alcohol control) and couples will be randomly assigned to a sexual communication condition (direct verbal or indirect verbal). Participants will be seated in a room separate from their partner, where they will drink an alcoholic or no-alcohol control beverage. Upon reaching a breath alcohol content (BrAC) of .08, or immediately after drinking in the No-Alcohol control condition, participants will complete a laboratory assessment of sexual violence. The main hypotheses are: (1) one's alcohol use will increase IPSV toward partners who are also drinking, (2) one's alcohol use will increase IPSV among partners who use indirect, relative to direct, sexual communication, and (3) actor alcohol use will increase IPSV toward partners who are also drinking and use indirect, relative to direct, sexual communication.
The purpose of the study is to evaluate the safety, efficacy, and pharmacokinetics of four single, increasing doses of CS-1103, given by intravenous (IV) infusion in otherwise healthy, non-treatment seeking participants with methamphetamine use disorder in the presence of a clinically relevant dose of methamphetamine HCl (30 mg IV).
The goal of this clinical trial is to examine how alcohol affects young adults' attention in both laboratory and real-world settings through phone-based cognitive tasks. The main questions this trial is designed to answer are: * How well do the phone-based cognitive tasks capture alcohol's effects on attention? * Does the effect of alcohol on attention contribute to risk-taking? Participants will complete cognitive tasks to assess attention before and after consuming a standard amount of alcohol in the laboratory, and during surveys completed through a phone app for eight weekends.
This human laboratory study will use cognitive, behavioral, and subjective measures to characterize impairment associated with co-use of alcohol and vaporized cannabis. Participants (n=32) will complete 7 double-blind, double-dummy outpatient sessions in randomized order. In each session, participants will self-administer placebo (0 mg THC) or active vaporized cannabis (5 or 25 mg THC, via a handheld vaporizer called the Mighty Medic) and a placebo drink (BAC 0.0%) or alcohol drink calculated to produce a breath alcohol concentration (BAC) of 0.05%. Participants will also complete a positive control session in which the participant administers placebo cannabis and alcohol at a target BAC of 0.08% (the legal threshold for driving impairment in most U.S. states).
The new recreational marijuana markets are contributing to polysubstance-impaired driving and other harms, especially when marijuana is used in combination with alcohol, by selling marijuana to obviously-intoxicated customers. In this study, the effectiveness of an intervention to reduce the risk of marijuana sales to obviously-intoxicated customers will be tested in the state-licensed recreational marijuana market in Oregon, one of the first states to ban such sales. The intervention will combine efforts by state regulators to increase deterrence of the state law prohibiting marijuana sales to obviously-intoxicated customers with training of store personnel to recognize signs of intoxication and refuse sales. It will also include testing the rate at which visibly intoxicated customers are refused alcohol at nearby establishments that sell alcohol either on-site or off-site
A Double-Blind Trial to Assess the Interaction Between ADX-629 and Ethanol While Exploring the Safety, Tolerability, and Activity of ADX-629 in Subjects With Elevated Ethanol Levels
This study will evaluate the individual and interactive effects of oral cannabis and alcohol on subjective and behavioral measures of impairment.
Sexual violence (SV) is a significant public health problem particularly among 18-24 year old populations. A major risk factor for SV is alcohol use, which via its negative impact on cognitive abilities and decision-making acts as a barrier to intervening in situations at-risk for a SV. This study has two main goals: (1) to determine the effects of proximal alcohol use on young (age 21 to 25) men's prosocial bystander behavior in situations considered at-risk for SV, and (2) to determine the efficacy of an evidence-based, web-based program called RealConsent, which has been augmented to include alcohol-specific content within the context of bystander SV ("RealConsent2.0"), on men's prosocial bystander behavior. The primary study endpoint is prosocial bystander behavior and will be assessed via two modes: (1) a virtual reality (VR) environment ("B-SAVE") and (2) a validated self-report measure of bystander behavior that has been modified to include assessment of proximal alcohol use and presence of alcohol within the context.
The hypothesis of this multisite Phase 2a study is that IXT-m200 will be well-tolerated in patients with acute mild to moderate METH toxicity. A randomized, open label design will be used in which one dose of IXT-m200 will be compared to treatment-as-usual (TAU). Approximately 40 participants will be enrolled in 4 cohorts. A dose escalation approach will be used so that progressively higher IXT-m200 doses will be evaluated in each cohort. In conjunction with safety monitoring, this design assures the opportunity to observe early safety findings before any participants are exposed to the next higher dose. The randomization ratio for IXT-m200 versus TAU is defined as 4:1 for each cohort so that the number of participants receiving TAU equals the number receiving each dose of IXT-m200 at the end of the study. Agitation scales and vital signs will be recorded to track effect of the antibody treatment versus TAU over time on agitation associated with METH use. While in the emergency department (ED), detailed and pertinent medical and psychiatric histories, and physical exam will be obtained, along with laboratory assessments and ECGs. In the ED, participants will give blood samples for analysis of METH and IXT-m200 concentrations and followed for development of adverse events. Participants will be evaluated at 2 days and 4 weeks after discharge from the ED for adverse events and drug use history. Cohort escalation reviews will be performed by the Sponsor, Medical Monitor, and Data and Safety Monitoring Board (DSMB) between cohorts and the next group will not start until after completion of this review.
Volunteers will receive a weight-based opioid (remifentanil) infusion for 10 minutes. In the first run, serial pupillary measurements (pupillary unrest, pupil diameter) will be taken at baseline, and at 2.5-minute intervals during the infusion and a 25-minute recovery period afterwards. After a washout period, the experiment will be repeated in each subject (second run). The two runs differ only by presence versus absence of verbal interaction.
Given the public health and social relevance of sexual aggression and the gap in the extant literature regarding state anger, emotion regulation, alcohol, and sexual aggression, the present study will contribute to our understanding of emotion regulation's role in sexual aggression perpetration. The proposed 2-year research plan will examine the effects of alcohol intoxication, state anger, and emotion regulation on men's sexual aggression intentions. This study will recruit non-monogamous, men (individuals who identify their gender as male and whose biological sex is male) who have sex with women, ages 21-35. While more research on female perpetrators is needed, the proposed study will exclusively recruit males for the following reasons: 1) the scientific literature indicating the majority of sexually aggressive acts are perpetrated by men; and 2) the current sexual aggression analog has not been piloted with female participants and would require preliminary experiments to determine its appropriateness. The study will utilize a 2x2 design in which participants are randomized to beverage condition \[alcohol (target BAC= .08gm%) or control (no alcohol control)\] and an emotion induction (anger induction or control). The outcomes will be assessed using a sexual aggression analog which participants will complete on the descending limb of alcohol intoxication and indicate the likelihood that they would engage in various sexually aggressive acts. The study also includes self-report measurements of state anger and emotion regulation to explore emotion regulation as a moderator in the associations among alcohol intoxication, state anger, and sexual aggression intentions.
The purpose of this study is to determine if an eye tracking impairment sensor can detect cannabis-induced impairment after using cannabis.The overall objective is to correlate measures collected from the eye tracking sensor with measures related to cannabis impairment (e.g., plasma THC levels, self-reported cannabis subjective effects, cognitive effects).
