104 Clinical Trials for Various Conditions
The purpose of this study is to assess the abuse potential of gabapentin enacarbil in healthy adult, non-dependent, recreational drug users.
Direct antiviral therapy (standard of care) administered to chronic hepatitis C-infected patients, in two hepatology clinics, who had used intravenous drugs in the past 6 months of signing informed consent (IC). This cohort was compared to concurrently treated chronic hepatitis C patients who were not intravenous drug users, who signed IC in these same clinics. Follow-up expected two years after cure and relapse rates recorded. Primary end point was SVR rate and secondary end points included reinfection rates in follow-up period.
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.
Alcohol use is a significant problem among Latinxs and immigration-related stress increases risk for substance use. A theoretically-based cultural adaptation of motivational interviewing (CAMI) that specifically integrated discussion of immigration-related stressors (e.g., stigma, social isolation) resulted in significant reductions in alcohol-related harms for those Latinx heavy drinkers with high discrimination compared to standard MI, and reduced anxiety and depressive symptoms one year later compared to MI. Rigorous tests that examine theoretically-informed adaptation of efficacious addiction interventions are not common, yet are needed to advance implementation science. This Hybrid Type 1 Effectiveness-Implementation study will investigate the feasibility of implementing CAMI in a real-world clinical setting. The key questions are: Would CAMI have positive effects among individuals who use both drugs and alcohol? How do providers view this intervention? The investigators will collaborate with a primary care center that serves a mainly Latinx client population to train their Community Wellness Advocates (CWAs) to deliver CAMI to patients who are heavy drinkers. The investigators will conduct a concurrent investigation on the process of implementing CAMI in primary care - a two-arm randomized clinical effectiveness trial will enroll Latinx heavy drinkers (18 years or older) in primary care who use alcohol (and may use other drugs) - and follow them for 12 months after the intervention. Specific Aims are: (1) To examine the impact of CAMI plus a booster session (vs. assessment only) on outcomes: % heavy drinking days, frequency of alcohol-related consequences, depressive/anxiety symptoms, and number of illicit drug use days, using a Hybrid Type 1 Effectiveness-Implementation design and (2) To gather indicators of implementation outcome from multiple stakeholders using a mixed-methods approach. The investigators will follow Curran's framework to evaluate the process of implementation and Proctor's framework to measure implementation outcomes. This study, a first to examine the acceptability of culturally-adapted addiction treatments in primary care settings, will answer essential questions on implementing evidence-based care for Latinxs that can improve health disparities related to substance use. Long term goals are to translate the lessons from this Hybrid study to the broader community to focus on population health for all primary care patients.
The unmet need for effective addiction treatment within the criminal justice system "represents a significant opportunity to intervene with a high-risk population" according to NIDA's 2016-2020 strategic plan. The plan also encourages the development and evaluation of implementation strategies that address the needs of the criminal justice system. The proposed research will be conducted as part of Dr. Zielinski's Mentored Patient-Oriented Research Career Development Award (K23), which aims to: 1) advance knowledge on implementation of a gold-standard psychotherapy for trauma, Cognitive Processing Therapy (CPT), in the prison setting and 2) examine whether prison-delivered CPT reduces drug use, psychiatric symptoms, and recidivism compared to a control condition (a coping-focused therapy). These foci have been selected because severe trauma exposure, substance use, and justice-involvement overwhelmingly co-occur in prison populations. The three specific aims in this research are: 1) Use formative evaluation to identify factors that may influence implementation and uptake of CPT in prisons, 2) Adapt CPT for incarcerated drug users and develop a facilitation-based implementation guide to support its uptake, and 3) conduct a participant-randomized Hybrid II trial to assess effectiveness and implementation outcomes of CPT with incarcerated drug users. Participants will include people who have been incarcerated (pre- and post-release from incarceration) and prison stakeholders who will be purposively sampled based on their role in implementation of CPT and other programs. Anticipated enrollment across all three Aims is 244 adult men and women.
The consequences of prescription opioid abuse are serious and the number of deaths from unintended overdose have quadrupled over the last 15+ years. Opioid analgesics remain among the most commonly abused class of substances in the United States. Moreover, patients who take pain medications for legitimate reasons may develop an opioid use disorder (OUD), with as many as 1 in 4 patients becoming dependent on their pain medications. Because of changing access to prescription opioid analgesics due to an increasingly negative prescribing climate and changes in guidelines, patients often turn to heroin, with an estimated 1 in 15 pain patients trying heroin within 10 years. Pain is a symptom that can be severely debilitating and needs to be treated adequately to improve the quality of life. Clinicians, then, are in a proverbial "catch-22" situation whereby treating a patient's chronic pain also exposes them to medications with substantial abuse liability and overdose risk. In this proposal, a method aimed at reducing the abuse potential of prescription opioid medications, without altering their analgesic efficacy, is described. The study team hypothesize that this can be accomplished by administering a fixed-dose-combination of an opioid with an atypical antipsychotic drug, in the same pill or capsule.
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 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.
Many people living with HIV use illicit drugs, which leads to worsened health outcomes and increased transmission of HIV due to poor adherence to medication regimens. This research will develop an intervention targeting medication adherence that is tailored to the unique needs of HIV-infected drug users. This research will promote adherence and improve treatment outcomes among HIV-infected drug users thereby minimizing the development of drug resistant strains of HIV and reducing transmission.
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.
Approximately one half of all Americans living with Hepatitis C virus (HCV) are drug users, yet they are the least likely to receive HCV treatment. Drug users are presumed non-adherent and therefore denied potentially life-saving therapy. This assumption can only be confirmed or dispelled through prospective pharmacologic and adherence studies in this population. Such studies would be greatly enhanced by an objective, quantitative measure of adherence which does not currently exist in the HCV field. Through the work proposed in this application, sixty HIV/HCV co-infected drug users will be treated with direct acting antiviral agents (DAA) and randomized to receive directly observed DAA therapy (DOT) vs. no directly observed therapy (no-DOT). Patients randomized to no-DOT will have wirelessly observed therapy (WOT) which involves use of a portable medication dispenser that sends a signal to a server with the date and time when the dispenser is opened. In Aim 1, DAA concentrations will be compared in those randomized to DOT vs. no-DOT. DAA pharmacokinetics will also be defined accounting for clinical factors like degree of hepatic impairment and use of concomitant recreational and antiretroviral drugs. The goal is to quantify adherence in this population and the effect of variable adherence on drug concentrations. In Aim 2, DAA concentrations (plasma, cellular, hair) will be linked with adherence patterns identified using WOT and DOT. The goal is to identify a drug concentration biomarker that predicts adherence in this population. In Aim 3, the relationship between DAA adherence (as measured by WOT and DOT and drug concentrations) and rate of cure will be established. The goal is to define the degree of adherence needed for HCV cure.
Antiretroviral therapy (ART) increases life expectancy and quality of life for individuals infected with HIV, and can reduce the chance of HIV transmission, but a high degree of adherence to ART is required to achieve these benefits. Unfortunately, only 59% of patients in North America report ART adherence \>90%. Thus, ART adherence interventions are a critical part of the fight against HIV/AIDS. Injection drug use and crack cocaine use are major factors in the transmission of HIV, and are associated with non-adherence to ART. Several types of interventions, most notably directly administered antiretroviral therapy (direct observation of antiretroviral administration and patient supports) and contingency management (the provision of incentives contingent upon objective evidence of adherence) have been effective in promoting ART adherence in drug users. However, a core problem with all ART adherence interventions is that their effects do not last after the interventions are discontinued. The common finding of post-intervention dissipation of effects suggests that ART adherence interventions may need to be long-term or even permanent adjuncts to ART for drug users. The investigators intend to develop an intensive intervention that incorporates the most effective techniques for promoting ART adherence in drug users, and delivers them in a manner that allows for their large-scale implementation as long-term or even permanent adjuncts to ART. Thus, we will bundle a targeted group of effective component interventions into a smartphone application that is easy for patients to use, simple to manage, and maximally convenient for all stakeholders. Our ultimate goal is to produce an intervention that is highly effective and scalable. Toward that end, the SteadyRX intervention to be developed under this project will be largely automated and will (1) facilitate consultation with care providers (2) provide reminders when a dose is overdue, (3) provide electronic remote observation of medication-taking, and (4) reward ART adherence. In addition to developing this smartphone-based intervention, a pilot study will be conducted in 50 HIV+ adults with a history of problem drug use. In this study, participants will be randomly assigned to receive usual care, or usual care plus the SteadyRX intervention.
Investigators propose a randomized controlled trial of women taking category D or X medications seen in family medicine, internal medicine or in the Coumadin Clinic. Women in the intervention group will receive an electronic medical record referral for teratogen counseling and contraceptive counseling with a follow up contraceptive provision appointment. The contraceptive counseling will be adapted from The Contraceptive CHOICE Project script and promote the use of the long acting reversible contraception. The women in the control group will also receive an electronic medical record referral and receive the teratogen counseling but only be told that it is important to avoid becoming pregnant. An initial survey will assess contraceptive knowledge and utilization. In addition, there will be telephone survey at 3 months and 6 months to assess contraceptive utilization and continuation.
We propose a randomized controlled trial (RCT) of the Skin intervention, compared to an assessment-only condition (both groups receive rapid HIV testing, a review of testing results, and brief HIV prevention counseling) among 350 injection drug users recruited during an acute medical hospitalization at Boston Medical Center. In the general hospital setting, injection drug users who otherwise might not seek care are accessible and teachable, and the presence of a drug-related illness can set the stage for patients to be more receptive to interventions2. We hypothesize that the Skin intervention will produce better outcomes at 1-, 3-, 6-, 9-, and 12-month(s) post-intervention.
The purpose of this exploratory study is to examine factors associated with frequency and type of internet and mobile technology use among illegal drug users, specifically use of internet and text-messaging to obtain health care information and engage in health care utilization, specifically human immunodeficiency virus (HIV) prevention and treatment services. We will target high drug activity neighborhoods in New York City and enroll participants recruited through targeted street outreach. All participants (n=336) will undergo an audio computer-assisted self-interview (ACASI) that will assess sociodemographics, health care access and utilization, sex/drug use behavior, health status, and characteristics of general and health-related internet/mobile technology use including factors that promote or hinder use. Participants identified as using the internet ≥1/month (n=151) will return for a 4-week ACASI to report on use of the pilot website (which will largely display information currently available in the community in print/ pamphlet/ video form).
Injection drug users (IDUs) constitute 60% of the approximately 5 million people in the U.S. infected with hepatitis C virus (HCV). HCV treatment leading to sustained viral response (SVR) is associated with increased survival. However, IDUs have had poor access to HCV care and their success in HCV treatment has been limited. With direct-acting antiviral agents, HCV treatment delivered within large clinical trials leads to SVR or cure in over 70% of genotype-1 infected patients, compared to 45% with previous therapies. However, SVR rates are as low as 14% in real-world settings. The majority of patients who fail to achieve SVR will develop drug resistance, but the optimal adherence level to minimize resistance is unknown. If HCV treatment continues to be delivered within current models of care, most IDUs will not only fail treatment and develop resistance, but may transmit resistant viruses to others. We have previously developed a multidisciplinary model of HCV care which integrates on-site primary care, substance abuse treatment, psychiatric care, and HCV-related care within opiate agonist treatment clinics. To maximize treatment outcomes, we piloted two models of intensive HCV-related care: directly observed therapy (DOT), and concurrent group therapy (CGT). In our DOT model, pegylated interferon is administered once weekly, if applicable, and one daily dose of oral medication is administered at the methadone window. In our CGT model, patients initiate HCV treatment within a once weekly treatment group which provides powerful social support to mitigate fears of side effects, promote efficient education, and deliver weekly injections, if applicable. It is unknown whether either model is better or more cost-effective than standard on-site care. PREVAIL 1: In the proposed study, 150 IDUs with chronic HCV (genotype 1) will be recruited from methadone clinics and randomized to one of three models of care: DOT; concurrent group treatment; or standard on-site care. Our specific aims are: 1) To determine whether either of two intensive on-site HCV treatment models (DOT or concurrent group treatment) is more efficacious than standard on-site treatment for enhancing adherence and SVR, and decreasing drug resistance; (2) To determine the incidence and factors associated with the development of drug resistance in IDUs; (3) To perform cost and cost-effectiveness analyses of each model; (4) To examine the impact of HIV coinfection on adherence and virologic outcomes among HCV-infected IDUs. PREVAIL 2: In the proposed study, 60 IDUs with chronic HCV (genotypes 1 2, 3 and 4) will be recruited from opiate agonist treatment programs and started on HCV treatment. Subjects will be offered the choice of model of care (either standard on-site, DOT, or concurrent group treatment). Our specific aims are: (1) to determine rates of adherence and SVR in a cohort of opiate agonist treatment patients initiating treatment with sofosbuvir-based regimens and (2) to determine adherence rates over time in drug users (genotype 3 and genotype 1 / IFN-ineligible) initiating a 24 week IFN-free regimen. PREVAIL 3: In the proposed study, 60 IDUs with chronic HCV (genotype 1 and 4) will be recruited from opiate agonist treatment programs and started on HCV treatment. Subjects will be offered the choice of model of care (either standard on-site, DOT, or concurrent group treatment). Our specific aims are: (1) to determine rates of adherence and SVR in a cohort of opiate agonist treatment patients initiating treatment with oral DAA combination of sofosbuvir and simeprevir or fixed dose of sofosbuvir and ledipasvir and (2) to determine adherence rates over time in drug users.
The goal of this study is to learn how injection drug use may affect the immune system.
To conduct a randomized clinical trial (RCT) of a community-friendly behavioral intervention designed to reduce HIV risk behavior among injection drug users (IDUs) in drug treatment by comparing risk-behavior outcomes of four weekly intervention sessions with a time-and-attention-matched control condition.
This study will test whether 3H+ (Holistic Health for HIV) is comparable to the original HHRP+ (Holistic Health Recovery Program) in reducing HIV risk behaviors and improving ART (Antiretroviral Therapy) adherence in a randomized controlled comparative effectiveness trial among 256 HIV+ persons in drug treatment who report unsafe injection drug use practices or sexual risk behavior.
More Americans are arrested for drug offenses than for any other crime. In 2009, over 294,000 arrests were made for possession of cocaine or heroin. Incarceration does not address the root problems and is frequently followed by relapse and re-arrest after release. In the case of opiate-dependent adults arrested for possession of heroin, one potentially effective alternative is to divert offenders to methadone maintenance treatment (MMT) as an alternative to adjudication of their case. MMT is an effective treatment for heroin dependence, and appears very effective for criminal offenders. However, cocaine use is common in MMT patients, including those with recent criminal justice involvement, and MMT alone is ineffective in addressing cocaine use. Continued cocaine use carries a substantial health burden and necessarily entails continued criminal activity. Thus, treatment for diverted opiate-dependent offenders should be designed to address cocaine use as well as opiate use. A Stage 1 Behavior Therapy Development project is planned over 2 years to adapt, manualize and pilot test the Therapeutic Workplace intervention for adults charged with heroin possession and offered diversion to methadone maintenance treatment as an alternative to adjudication of their case. The Therapeutic Workplace is a novel, employment-based contingency management intervention that has been very effective in promoting cocaine abstinence in adults who use cocaine persistently during methadone treatment. In the Therapeutic Workplace, participants are hired in a model workplace and required to provide drug-free urine samples to work and to earn maximum pay. Once we develop and manualize the adapted version of the Therapeutic Workplace for adults arrested for heroin possession, a pilot test will be conducted. Individuals identified by the State Attorney's office as candidates for diversion will be assessed for study eligibility. Given the high rates of injection drug use and injection-related transmission of HIV in Baltimore, this study will be restricted to injection drug users to evaluate the potential utility of this intervention in reducing HIV risk. Eligible individuals will be offered methadone maintenance in lieu of prosecution and will be required to remain in methadone treatment for 90 days. All participants will receive standard MMT, independent of whether they decide to participate in the pilot study. After beginning MMT, participants will be invited to enroll in the pilot study and randomly assigned to two study groups. Participants assigned to the Usual Care Diversion group will receive the standard MMT. Participants assigned to the Therapeutic Workplace Enhanced Diversion group will receive the standard MMT and the Therapeutic Workplace intervention. The data from this pilot study will serve as the foundation for a full-scaled randomized controlled trial. Overall, the Therapeutic Workplace could serve as a novel and ideal intervention for many heroin dependent adults involved in the criminal justice system. The use of MMT in lieu of adjudication in combination with the Therapeutic Workplace could increase drug abstinence and employment and decrease HIV risk and criminal activity in this refractory high-risk population.
Primary Objective: This study will evaluate the most effective strategy in achieving HIV virologic suppression among HIV-infected substance users recruited from the hospital setting who are randomly assigned to one of three treatment conditions: 1) Patient Navigator (PN); 2) Patient Navigator + Contingency Management (PN+CM); and 3) Treatment as Usual (TAU). Primary Hypothesis: The rate of viral suppression (plasma HIV viral load of \<= 200 copies/mL) relative to non-suppression or all-cause mortality in the 3 study groups will differ from each other at the 12 month follow-up. Sub-hypothesis 1. The rate of virologic suppression (plasma HIV viral load of \<= 200 copies/mL) in the PN+CM group will be greater than that in the TAU group. Sub-hypothesis 2. The rate of virologic suppression in the PN+CM group will be greater than that in the PN group. Sub-hypothesis 3. The rate of virologic suppression in the PN group will be greater than that in the TAU group. Secondary Objectives: 1. To evaluate the effect of the experimental interventions on: HIV virological suppression and CD4 T-cell count changes at 6 months post-randomization; engagement in HIV primary care and visit attendance; and rate of hospitalizations. 2. To evaluate the effect of the experimental interventions on: drug use frequency and severity; and drug use treatment engagement and session attendance. 3. To assess selected mechanisms of action of the intervention (.i.e. mediators of intervention effect). 4. To assess potential characteristics associated with differential treatment effectiveness (i.e. moderators of intervention effect). 5. To evaluate the incremental cost and cost-effectiveness of the interventions.
The principal goal of this research project is to evaluate the natural history of HCV and liver disease and its treatment in HIV-infected persons who use drugs. Research procedures will focus on determining liver disease prevalence and severity within this population. This is an observational study without study specific interventions.
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.
HIV infected drug users have greater difficulty adhering to highly active antiretroviral therapy compared to non-drug users. As sustained adherence to highly active antiretroviral therapy is critical to reducing HIV related morbidity, mortality, and reducing the spread of HIV, innovative and potentially sustainable treatment strategies that can optimize the durability of adherence enhancing interventions among drug users is urgently needed. The goal of this study is to further develop and pilot test a smartphone based intervention called HEART (Helping Enhance Adherence to Retroviral therapy using Technology) to HAART, to enhance adherence to HAART among HIV infected drug users.
The goal of the proposed project is to determine the effectiveness of a brief motivational intervention among Emergency Department (ED) patients who use cocaine and/or heroin to prevent Sexually Transmitted Infections (STIs) and Human Immunodeficiency Virus (HIV) by comparing cumulative incidence and frequency of safe sex behavior between intervention and standard voluntary counseling, testing and referral to substance abuse treatment (control) groups over a one year follow-up period.
The investigators will develop and test the feasibility and promise of a combined HIV adherence assessment and intervention application for rural drug users using an available, familiar technology whose reach will grow exponentially: text messaging via mobile phones. By 2007, 84% of U.S. residents had mobile phones, with near 100% mobile phone penetration projected by 2013. While technology adoption is often slower in under-served communities, the trend is different with mobile phone technology. African-Americans are using more mobile phone minutes per capita and increasing their use at a higher rate compared with other ethnic groups. This technology has great potential to reduce health disparities. In this project, the investigators will develop and test the feasibility and promise of a text messaging application and system using Ecological Momentary Assessment methods to detect nonadherence and drug use and immediately intervene to improve HIV treatment adherence in drug users living with HIV/AIDS who reside outside major metropolitan areas. This R34 is a Stage 1b/2a project in the Stage Model of Behavioral Therapy Development that will develop novel interventions and methods, and generate preliminary estimates of effect sizes that will determine whether a larger clinical trial with extended follow-up and cost-effectiveness evaluation is warranted. The specific aims of this project are: 1. To identify assessment and intervention features relevant to the adherence barriers and drug use patterns of rural and non-urban HIV+ drug users using formative methods including: * structured interviews and focus groups to identify specific barriers to adherence and engagement in care and needs related to drug craving and drug use that should be addressed by the intervention * iterative usability testing of components and drafts of the intervention 2. To create a text messaging mobile phone application and system (Treatment Extension by Texting, Text) to assess and improve HIV treatment adherence and drug use in real time --Text will be built upon a piloted unidirectional personalized text phone application and system, STeM, and will include pre- and post-programming usability testing 3. To test the feasibility and promise of the assessment and intervention tool in a randomized pilot trial of rural HIV+ drug users with detectable viral load (VL) comparing Text to usual care * Feasibility: Identify recruitment rates, consent rates, participant flow, completion rates, and variance of key covariates and outcome variables * Promise: determine point estimates and the precision of effects for primary and secondary adherence outcomes including pharmacy refills and unannounced pill counts (medication adherence), missed visit percentage (treatment engagement), VL, and drug craving and drug use.
The purpose of the study is to compare, contrast, and characterize the range of user perceptions and potential acceptability of three (3) topical vaginal microbicide dosage forms.
Cigarette smoking is very common in current and former injection drug users and is known to cause chronic lung diseases. Quitting smoking is proven to improve the health of people addicted to cigarettes. . Little information exists regarding the perceptions and characteristics of drug users regarding quitting smoking. Additionally, most programs designed to help people quit smoking are not very successful. One reason these programs may not work well is because it is difficult to motivate people to quit smoking. New methods of motivating changes in behavior include small monetary payments for healthy behavior and reporting breathing tests with the concept of "lung age," which is the age of an average healthy person with similar breathing test results. For example, a health care provider can report results as "Although you are 50 years old, you have the lungs for a 70 year old". In this proposal, the investigators plan to first explore the beliefs and characteristics of current and former injection drug users and how they are related to quitting smoking. The investigators then plan to study whether the use of two new methods of motivation increases the chances that this group will stop smoking.
PRO 140 2102 is a phase 2b, national, multicenter, randomized, double-blind, placebo-controlled study in order to evaluate the safety and efficacy of PRO 140 (anti-CCR5 monoclonal antibody) administered subcutaneously as an adjunct to a new, optimized, oral antiretroviral regimen in HIV-infected injection drug users with viral rebound and documented poor adherence to the previous antiretroviral regimen.
