10 Clinical Trials for Various Conditions
The purpose of this study is to determine the pharmacokinetics and pharmacodynamics of oral delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) and to evaluate detection of recently smoked THC in oral fluid.
The purpose of this study is to determine the pharmacokinetics and pharmacodynamics of inhaled cannabis with varying amounts of delta-9-tetrahydrocannabinol (THC), and cannabidiol (CBD) and to evaluate detection of recently smoked THC in oral fluid.
The purpose of this placebo-controlled study is to evaluate the safety, tolerability and pharmacokinetics of a single dosage of human butyrylcholinesterase (HuBChE) in healthy adults. HuBChE, which occurs naturally in human plasma, is being evaluated for prophylaxis and treatment in the event of exposure to chemical nerve agents (as employed during chemical warfare or as an act of terrorism). Volunteers will receive a single intramuscular infusion of either HuBChE or normal saline placebo. The volunteers will remain in the study for 90 (+/- 7) days. For the first 3 days following dose administration, they will remain at the clinical trial site as an inpatient and will be closely monitored for patient safety. Afterwards, they will return to the trial site (at pre-determined intervals) as an outpatient for a further 8 visits, where patient safety will be assessed.
The purpose of this placebo-controlled study is to evaluate the safety, tolerability and pharmacokinetics of a single dose regimen of human butyrylcholinesterase (HuBChE) in healthy adults at 3 ascending dosage levels administered IV. HuBChE, which occurs naturally in human plasma, is being evaluated for prophylaxis and treatment in the event of exposure to chemical nerve agents (as employed during chemical warfare or as an act of terrorism). Volunteers in each dosage cohort will be randomized to treatment with HuBChE active drug or normal saline placebo in a 3:1 ratio. The volunteers will remain in the study for 90 (+/- 7) days. For the first 3 days following dose administration, they will remain at the clinical trial site as inpatients and will be closely monitored for patient safety. Afterwards, they will return to the trial site (at pre-determined intervals) as outpatients for 8 further visits, where patient safety will be assessed.
Current standard of care prior to determination of brain death in subjects with suspected anoxic brain injury is to exclude complicating medical conditions that may confound clinical assessment (such as severe electrolyte, acid base, endocrine or circulatory disturbance), achieve normothermia and normal systolic blood pressure over 100 mmHg (with or without vasopressor use), exclude the presence of neuromuscular blocking agents (with the presence of a train of 4 twitches with maximal ulnar nerve stimulation) as well as to exclude the presence of CNS depressant drug effects. At the present time the latter is done by history, drug screen and allowing enough time for paralytic and sedative drugs to be metabolized and cleared from the body. Clearance is calculated by using 5 times the drug's half-life assuming normal hepatic and renal functions. Half-life can also be prolonged in subjects who have been treated with induced hypothermia. Literature search revealed articles with general guidelines and approaches to brain death, but none addressed pharmacological reversal of sedative drugs
This protocol has three purposes: (1) to evaluate subjects for inclusion or exclusion from other NIAAA protocols; (2) to provide a common set of descriptive information that will be available on all NIAAA research subjects; (3) to allow NIAAA medical and nursing staff to treat alcoholic patients for acute alcohol intoxication or alcohol withdrawal before requiring patients to consent to evaluation for participation in research studies. Information collected will include such items as psychiatric diagnoses, presence or absence of brain, liver or other organ damage, history of the amount of past alcohol consumption, other substance use and family history of alcoholism. This information will allow investigators to determine for which, if any, NIAAA research studies a subject is eligible. In order to avoid requiring intoxicated subjects to consent for procedures such as HIV testing, psychiatric interviews, and Magnetic Resonance Imaging (MRI) of the brain we will obtain consent from all alcoholic subjects in two phases, using two separate consent forms. The first consent form will express the subject's desire to be admitted to the NIAAA inpatient unit for the purpose of treatment for alcoholism and will authorize only medical evaluation and treatment for alcoholism and associated problems. After an alcoholic subject has been admitted to the inpatient unit and is judged to be no longer intoxicated or suffering from acute alcohol withdrawal he or she will be presented with the second consent which will describe the evaluation for participation in other NIAAA research studies. Non-alcoholic, healthy controls will sign only one consent form describing the data to be collected and evaluation for participation in other NIAAA research studies.
This study will assess the age-dependent effects of smoked and oral THC on abuse liability, intoxication, analgesia and impairment as a function of age.
This will be a retrospective study with data collected from the trauma registry. We plan to complete the data collection and analysis by 12/31/2020. Data on ride sharing will be obtained from the Uber and Lyft websites. Data pertaining to number of alcohol- and drug-related motor vehicle (and auto-ped) collisions will be obtained from the Texas Department of Transportation website, the National Highway Traffic Safety Administration, the Shared-Use Mobility Center (SUMC) and the Transformation of Public Transit, the Texas A\&M Transportation Institute, Texas Department of Public Safety, and the U.S. Department of Transportation website (or equivalent). Sexual assault data will be obtained as available the Sexual Assault Nurse Examiner (SANE) database as well as from Turning Point Rape Crisis Center and surrounding hospitals in the Dallas area as well as the Uber report for sexual assaults.
Subjects will participate in a 4-visit study protocol in which they will be asked to complete a set of computerized tasks and a 45-minute simulated drive in a driving simulator. Subjects will be administered marijuana of varying pre-determined concentrations of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) during 3 of the visits and alcohol during one of the visits. Throughout the duration of each visit, brain activity will be measured noninvasively using an electroencephalogram (EEG) headset. The purpose of this study is to: 1. Further understand the effects of acute cannabis intoxication on driving performance in a driving simulator 2. Develop and refine brain-based biomarkers of impairment due to acute cannabis intoxication
The aim of this study is to develop information about the acute and residual effects of a new product being targeted to young adults. Using a double placebo-controlled 2 X 2 factorial model study design, we will compare the acute and residual effects on driving impairment of caffeinated alcohol, non-caffeinated alcohol, caffeinated placebo, and non-caffeinated placebo. Under the alcohol conditions, participants will receive sufficient alcoholic beverage to attain a blood alcohol concentration (BAC) of .12 g%. Participants will be 144 undergraduate and graduate students, and recent college graduates.
