Filter by:The goal of this observational clinical study is to is to learn more about how commercial kratom products affect healthy adults who consume them regularly. The main questions it aims to answer are: 1. What are the acute physiological, subjective, and cognitive effects of kratom following participant self-administration of a single oral dose of the participants usual kratom product at the participants typical dose? 2. What are the physiological, subjective, and cognitive effects associated with kratom product discontinuation among adults who use regularly? 3. What are the pharmacokinetics of kratom products consumed by adults who use regularly? On the first study day: Under direct observation, participants will self-administer a single oral dose of the participants own commercial kratom product that that is regularly taken and will consume it at the participants self-selected typical dose/serving. Following this, serial blood draws and urine collection will occur along with administration of validated questionnaires, tests, and continual monitoring. After this first study day, participants will no longer be permitted to use any of the participants kratom product during the study. On study nights/days 2-3: participants will reside a clinical research unit and be observed and evaluated for kratom withdrawal syndrome.
The goal of this project is to rigorously evaluate the nature of e-cigarette withdrawal in exclusive e-cigarette users during a monitored abstinence period and the role of nicotine in the expression of this withdrawal syndrome.
A randomized, open-label, controlled, ascending dose cohort, PK, and safety study assessing standard of care (i.e., non-pharmacologic measures and morphine when indicated) with or without lofexidine for the treatment of opioid withdrawal symptoms in neonates due to intrauterine exposure to opioids, described as neonatal opioid withdrawal syndrome (NOWS) or neonatal abstinence syndrome (NAS). This study has been designed to assess the pharmacokinetics (PK) and safety of the lofexidine in neonates experiencing NOWS. The effectiveness of lofexidine on the severity of NOWS will also be evaluated. Results from this study will be used to support dosing recommendations in neonates and to inform further studies in the pediatric patient population.
A placebo-controlled trial in which male and female outpatients with an opioid use disorder who express interest in extended-release injectable naltrexone (XR-NTX) are randomized 1:1 to lofexidine/pregabalin or lofexidine/pregabalin placebo for withdrawal management and offered XR-NTX if after completing withdrawal.
This clinical trial will help us learn more about how to best care for babies with Neonatal Opioid Withdrawal Syndrome, also called NOWS. Babies with NOWS often have tremors, a hard time sleeping, excessive crying, and trouble feeding. Some babies that have NOWS need medicine. Doctors have two ways of providing medicine that are widely used today: 1. Scheduled opioid taper approach. The baby gets medicine at regular times. As symptoms get better, the amount of medicine the baby gets decreases until the baby no longer needs medicine. This is called a medicine taper. 2. Symptom-based approach. The baby will only get medicine when they show signs of NOWS, instead of at regular times. If the baby is showing no signs of NOWS, no medicine will be given. We are doing the OPTimize NOW study to figure out the best way to give medicine to babies with NOWS.
Infants with neonatal abstinence syndrome (NAS) experience prolonged hospital stays and poor neurodevelopmental outcomes, in-part because of the lack of accurate, individualized, biologic assessments available to manage this increasingly common medical condition. The proposed study will define the molecular mechanisms that regulate the response to opioid withdrawal in the developing brain by focusing on three candidate microRNAs (let-7a, miR-146a, miR-192) that have been shown to respond to opioid exposure in animal models and adults, and are impacted in both my preliminary study of infants with NAS, and my human neural progenitor cell (NPC) design of opioid withdrawal. By determining the mechanism through which microRNAs impact NPC differentiation in opioid withdrawal, and determining whether exosomal salivary microRNA levels predict treatment dose and neurodevelopmental outcomes in infants with NAS, this study will enhance our knowledge of NAS-related biology and identify potential biomarkers that could improve medical care for this important medical condition.
Kratom is used for stimulant, analgesic, anxiolytic, and sedative effects. There is inadequate knowledge about Kratom addiction. Kratom withdrawal may be treated like opioid withdrawal. Prospective observational crossover study of consenting adults who are undergoing Kratom withdrawal management. On alternate weeks, each patient receives treatment using Buprenorphine 5cmg/hr patch; or Clonidine tablet 0.1mg 4hourly; or combined Clonidine tablet 0.1mg 4hourly + Buprenorphine 5cmg/hr patch. Each patient will undergo treatment for 12 weeks. Patients will use Subjective Opiate Withdrawal Scale (SOWS) to collect data on daily basis. SOWS is a patient-administered tool that is used to record the severity and presence of opiate withdrawal. The physician will also use Clinical Opiate Withdrawal Scale (COWS) to collect data on weekly basis. COWS is a clinician-administered tool that is used to record the signs of opiate withdrawal. A change in the COWS and SOWS scores by 6-points is considered significant.
This study is being done to answer the question: what is the effect of Vagal Nerve Stimulation (VNS) dosing on opioid withdrawal responses in individuals with a history of Opioid Use Disorders (OUDs)? Eligible participants will be in the study for one week in an inpatient research hospital stay, have an MRI scan, and have a follow-up call 1-3 months after their inpatient stay. Participants will complete several psychiatric questionnaires/interviews, physiological monitoring with several devices, brain imaging, and VNS testing.
A major challenge to seeking treatment for opioid use disorder (OUD) is the withdrawal symptoms associated with cessation of opioid use. The signs and symptoms of opioid withdrawal include irritability, anxiety, muscular and abdominal pains, chills, nausea, diarrhea, yawning, runny eyes and nose, sweating, sneezing, weakness, and insomnia. The current gold standard of treatment involves a gradual reduction of the opioid drug dosage (tapering). However, as all opioids have potential for abuse and require careful dosing due to side effects (e.g., respiratory depression), a non-opioid medication to facilitate withdrawal severity would be of great value. Commonly used non-opioid medications like lofexidine have concerning side effects including sedation and low blood pressure. BioXcel Therapeutics has developed BXCL501 (dexmedetomidine: sublingual film) to reduce symptoms associated with opioid withdrawal. Dexmedetomidine is currently used as an intravenous anesthetic for its anxiety-reducing, sedative, and analgesic properties. The current study will seek to compare the safety and efficacy of BXCL501 relative to lofexidine and placebo in subjects with OUD who are physically dependent on opioids. Throughout a 7-day inpatient withdrawal period (using a methadone taper) opioid-dependent participants will receive sublingual BXCL501, placebo, or lofexidine. In comparison to lofexidine, dexmedetomidine is expected to have a superior safety profile with limited adverse effects on blood pressure and heart rhythm. Three sites will participate in this study: NYSPI, Clinilabs, Inc., and Yale University.
The investigators propose a rigorous, Phase II, three-group, placebo-controlled double-blind randomized controlled trial (RCT) to evaluate the efficacy of buspirone for both withdrawal and craving among individuals with opioid use disorder (OUD) undergoing a standardized stepwise taper. During this 10 to 12-day residential study, participants with OUD will be enrolled, stabilized on a short-acting opioid, undergo an opioid stepwise taper, and complete a post-taper observation period where participants will have the opportunity to initiate long-term buprenorphine or extended-release naltrexone.
