Major Depressive DisorderOpioid-use DisorderThis trial is a randomized, double blind, controlled pilot study that will compare bilateral theta burst stimulation (TBS) and sham treatment for patients with opioid use disorder (OUD) and Major Depressive Disorder (MDD) experiencing suicidality.
Evaluating the Safety of Acute Baclofen in Methadone-maintained Individuals With Opiate Dependence....
Addiction OpiateOpiate addiction is a major health challenge. The mainstay of treatment is opiate substitution therapy (OST), typically methadone, but many desire to be opiate-free. Abstinence in older opiate addicts with increasingly complex health needs may also be advantageous. Detoxification generally involves tapering of OST with adjunct medication to treat emerging symptoms, but these are often ineffective or inappropriate for longer-term prescribing. New treatments are therefore needed. The investigators propose that baclofen has the desired properties to facilitate OST detoxification. It is licensed for spasticity, is currently used to treat alcoholism and there is promising pre-clinical and clinical evidence of potential efficacy in opiate dependence. Common symptoms of withdrawal are likely to be improved by baclofen. Whilst the investigators clinical experience and other studies suggest baclofen can be taken safely with methadone, they could potentially interact causing adverse effects such as respiratory depression. Also, the possibility of abuse liability remains unexplored and is an important consideration in this indication. The investigators will therefore determine the safe dose combinations of baclofen and methadone and to assess if baclofen is 'liked'. Patients engaged in treatment for opiate dependence from community addiction services and receiving stable doses of OST with methadone will be invited to undergo screening at the Imperial Clinical Research Facility (ICRF) at Hammersmith hospital, or at their local addiction clinic. Up to 64 eligible patients will attend the ICRF for an experimental visit. Acute baclofen or placebo will be orally administered (randomised, single-blind, 3:1 ratio respectively) with the dose determined by a Bayesian adaptive trial algorithm. Measures will comprise respiratory, sedation, self-report and cardiovascular monitoring, and blood sampling for 5 hours post-dose. The study duration will be ~2-3 weeks from pre-screening phone call to the post visit follow up phone call.
Integrated Outpatient Treatment of Opioid Use Disorder and Severe Injection Related Infections
Drug UseOpioid-use DisorderThis study will assess the efficacy of an integrated outpatient treatment model for persons with opioid use disorder and injection related infections. The investigators hypothesize that outpatient antibiotic treatment coupled with comprehensive treatment for opioid use disorder will demonstrate a safe and effective way to manage patients. Results could improve the current protocols for the treatment of individuals with opioid use disorder and severe infections.
Cannabidiol in Opioid Use Disorder and Chronic Pain
Chronic PainThis is a double-blind, randomized, placebo-controlled cross-over human laboratory study with a duration of approximately 3 weeks, during which participants will come to the testing site for a total of five times: one initial screening session, and four experimental sessions where study medication, Cannabidiol (CBD) will be administered, separated by at least 72 hours to limit carryover effects.
Efficacy of Buprenorphine and XR-Naltrexone Combination for Relapse Prevention in Opioid Use Disorder...
Opioid-use DisorderThis study will evaluate the effectiveness of a new pharmacological approach to increase efficacy of treatment with extended release naltrexone (XR-naltrexone) for individuals with opioid use disorder by combining it with buprenorphine-naloxone. This is a two arm, double-blind, placebo-controlled study to examine whether addition of buprenorphine-naloxone will improve treatment retention, reduce opioid craving, and improve mood over 24 weeks of treatment with extended release naltrexone (XR-naltrexone) administered every four weeks for a total of 6 injections.
Smartphones for Opiate Addiction Recovery
Opioid-use DisorderTreatments for opioid addiction exist, but effectiveness is compromised when subjects use illicit opiates during treatment. Reuse rates during treatment can be high, and reducing illicit opiate use during treatment has thus recently become a major NIDA policy goal. The 5-minute battery indicates the numerical probability that a patient will reuse illicit opiates within the next 7-10 days.
Adjunctive Transcranial Stimulation to Reduce Impulsivity in Opiate Use Disorder
Opioid-use DisorderTobacco Use DisorderThe goal of this study is to examine the effect of four sessions of theta burst stimulation (TBS) versus sham TMS on attentional bias for smoking and opioid cues versus neutral stimuli in a population of patients with tobacco use disorder (TUD) with comorbid opioid use disorder (OUD) that is stable and on treatment with buprenorphine. The investigators will also examine the effect of TBS on craving for cigarettes as well as opioids. Participants will perform a stress induction procedure that mirrors an optimum combination of cues that trigger tonic craving in their environment while exposed to stress. All four sessions of TBS/sham TMS will be performed on the same day, with each session lasting for approximately 10 minutes and separated by 50 minute intervals.
An Adaptive Walking Intervention to Manage Chronic Pain in Veterans With Opioid Use Disorder Engaged...
Opioid Use DisorderChronic PainSevere chronic pain and opioid use disorder (OUD) occur at significantly higher rates in Veterans compared to the general population. Chronic pain often persists despite engagement in opioid agonist treatment (OAT), the first line treatment for OUD. Recent VA guidelines strongly recommend non-pharmacologic treatment for chronic pain, but individuals with OUD are frequently excluded from pain treatment studies. There is a need for evidence-based pain treatments that compliment OAT for Veterans with chronic pain and OUD. In this study, the investigators will determine feasibility and acceptability for a behaviorally focused pain treatment that includes pain education and a pedometer assisted adaptive walking program for Veterans receiving OAT for OUD. Potential treatment outcomes will be repeatedly assessed using a mobile device, and study-provided pedometers. By offering pain treatment within OAT clinical care, the investigators hope to decrease stigma and increase access for Veterans with chronic pain and OUD.
EA for Protracted Withdrawal of OUD
Opioid-Related DisordersOpioid use disorder (OUD) the most harmful of all the illicit drugs is a serious substance-related disorder resulting from abuse or misuse of opioids. Huge number of patients are addictive to opioid and evidences show that patients with OUD have high rates of infectious diseases.The "World Drug Report 2020" has declared that 58 million people used opioids in 2018 and some 35.6 million people suffered from drug use disorders globally. More than 11 million people inject drugs, while 1.4 million PWID are living with HIV, 5.5 million with hepatitis C and 1.2 million are living with both hepatitis C and HIV. The long-term physical and mental symptoms of some opioid drug users after detoxification treatment are called protracted opioid withdrawal syndrome (POAS). POAS is one of the important causes of relapse. Methadone maintenance treatment is the most widespread and extensively researched treatment for heroin addiction and has been shown to reduce the frequency of opioid use, the mortality, and the transmission of human immunodeficiency virus and viral hepatitis. But higher daily methadone dose and increasing duration of treatment conduce the addiction in methadone. Other medication therapy like naltrexone treatment is also associated with high rates of noncompliance and opioid relapse. Meanwhile, relapse to heroin use following cessation of agonist maintenance treatment is common. The problems associated with use of opioid agonists have made it necessary to develop non-opioid therapies to ameliorate the symptoms of acute and protracted opioid withdrawal. Acupuncture based on traditional Chinese medicine (TCM) theory is becoming a popular complementary and alternative treatment worldwide. Study showed that acupuncture reduced the depression symptoms and cravings of patients under methadone maintenance treatment. Another study by Le et al. (2016) showed that electric acupuncture has been associated with a reduction in depressive symptoms through the adjustment of HPA axis function and increasing the hippocampus activity. And also some research show the efficiency of acupuncture in treating mice with OUD. Investigators conduct a pragmatic randomized controlled trials(pRCT) to observe the effect of acupuncture in a larger sample. It combines the advantages of randomization and real-world data, and the results can provide the best real-world evidence for the assessment of intervention effects or comparative effects.
Enhancing Exercise and Psychotherapy to Treat Pain and Addiction in Adults With an Opioid Use Disorder...
Opioid Use DisorderPainThis work will involve conducting a randomized trial that will evaluate preliminary efficacy of "assisted" rate cycling, voluntary rate cycling and psychotherapy for pain individually and in combination as adjunctive treatments on cravings (primary outcome) in adults with an opioid use disorder. The investigators will also evaluate the effects of "assisted" rate cycling, voluntary rate cycling and I-STOP on secondary outcomes including depression, anxiety and sleep.
