Filter by:The primary objective of this study is to assess the efficacy and safety of TV-1380 [Recombinant human serum albumin (HSA) mutated butyrylcholinesterase (AlbuBChE)] in facilitating abstinence in cocaine-dependent subjects.
The purpose of this study is to evaluate if exercise added to usual treatment improves cocaine dependence treatment. The primary objective of this study is to investigate if exercise can facilitate cocaine craving reduction. The secondary aims are to evaluate if exercise can reduce negative mood states, improve quality of life and facilitate abstinence of cocaine.
The investigators' recently completed study has provided the first evidence that administration of the medication propranolol, following exposure to cocaine cues, can alter drug-associated memories and reduce craving and other drug cue-elicited responses in cocaine addicted persons. The investigators will attempt to augment this effect by a) doubling the number of propranolol-medicated cocaine cue exposure (CCE) retrieval sessions and b) increasing the dose of propranolol. It is expected that propranolol treated groups, relative to placebo treated groups, will evidence greater reduction of craving, cue reactivity and cocaine use during follow-up cocaine cue exposures. Also, these effects will be greater for those who receive 80mg of propranolol as opposed to 40mg.
Crack addiction has become a severe health problem in Brazil. Today, crack addiction is the primary cause for inpatient treatment for all illicit substances. When compared to cocaine, crack users develop much faster diagnoses for crack dependence, shows a more compulsive pattern of use, has higher probability of living or have lived in the streets, and of engaging in illegal activities. Consequently to this, mortality of crack addicts is 7 times higher than for the rest of the population. Despite all efforts being made for the development of effective pharmacological treatments for stimulant addiction (crack included), up to today, there is no robust evidence of efficacy of any pharmacological treatment. For that reason, the use of evidence based psychosocial interventions is so important for treating this population. Although today open treatment facilities in Brazil are more and more starting to use evidence-based interventions such as motivational interviewing, cognitive behavior therapy, relapse prevention and coping skills, such treatments present very modest results when treating crack addiction. The biggest difficulties encountered when treating this population are maintaining patients in treatment, reducing crack use and achieving continued abstinence. A psychosocial treatment based in behavioral principals' named Contingency Management (CM) is widely applied in the USA. Recent meta-analyses and review studies present robust evidence that, when applied alone or in adjunction with other psychosocial and pharmacological treatment, CM is the most effective treatment for what regards, treatment retention, reducing drug use and promoting continued abstinence. The purpose of this study is to evaluate if Contingence Management (CM) can be affective in the treatment of crack addiction in Brazil. To accomplish this, 60 individuals (male and female from 18 to 65 years of age) seeking open treatment for crack addiction will be randomized to 2 treatment conditions (Standard treatment (ST) or ST+CM. Both treatments will last 12 weeks with 3 and 6-month follow-up. In both groups patients will be encourage to leave urine samples 3 times week. Hypotheses: Patients receiving ST+CM will stay longer in treatment, have more negative tests for cocaine/crack, and achieve longer periods of cocaine/crack abstinence when compared to patients receiving ST alone.
The proposed protocol is a multi-site double-blind, placebo-controlled outpatient study of the safety and efficacy of Adderall-XR (MAS-ER) and topiramate in the treatment of cocaine dependence. 198 patients will be enrolled and 176 patients randomized in a 14-week trial. The proportion of participants achieving sustained cocaine abstinence for three consecutive weeks at the end of the study will be significantly greater for the combined pharmacotherapies group compared to the placebo group.
Cocaine dependence involves problematic neuroadaptations, such as heightened reactivity to cocaine cues, that may be responsive to pharmacological modulation of glutamatergic circuits. Despite promising preclinical findings with n-methyl-d-aspartate receptor (NMDAr) modulators, studies with human subjects have been unsuccessful to date. The purpose of this investigation is to examine the effects of the NMDAr antagonist ketamine, recently found to have potent therapeutic effects in humans, on cue-induced craving and impaired motivation for quitting cocaine in cocaine dependent participants, 24-hours post-infusion.
Modafinil has been reported to reduce cocaine use in a clinical sample of infrequent users (2 days/week), but the effects of modafinil on cocaine self-administration in the laboratory have not been studied. The present study investigated the effects of modafinil maintenance on cocaine self-administration by frequent users (4 days/week) under controlled laboratory conditions. During this 48-day double-blind, crossover design study, the effects of modafinil maintenance (0, 200, and 400mg/day) on response to smoked cocaine (0, 12, 25, and 50 mg) were examined in nontreatment seeking cocaine-dependent individuals (n = 8).
The purpose of this study is to examine the role of progesterone (a hormone found in both men and women) on stopping cocaine use. The study will examine whether the medication, in combination with behavior therapy will decrease cocaine use, cigarette smoking, withdrawal symptoms, impulsivity and stress.
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.
The primary objective of this study is to collect pilot data on the efficacy of D-serine, relative to placebo, as a cocaine dependence treatment. Secondary objectives include evaluating D-serine, relative to placebo, on: 1. safety in treating cocaine-dependent adults and 2. tolerability.
