The objective of this study is to evaluate the efficacy and safety of lorcaserin in the treatment of cocaine use disorder.
The study will test the efficacy of a hour long, one-on-one, active listening counseling session (called Change the Cycle or CTC) aimed at reducing behaviors among active people who inject drugs (PWID) that research has found to facilitate uptake of injection drug use among non-injectors. The study will involve ~1,100 PWID who will be randomized to CTC or an equal attention control intervention on improving nutrition. Participants will be recruited in Los Angeles and San Francisco, California and followed up at 6 and 12 months to determine changes in direct and indirect facilitation of injection initiation among non-injectors.
There has been recent interest in the role of the 5-HT1B receptor as a possible modulating factor in cocaine dependence, certainly in preclinical models. The Yale Positron Emission Tomography (PET) Center has developed a novel 5-HT1B receptor antagonist radioligand, [11C]-P943, which has been validated in human studies. We hypothesize that the 5-HT1B receptor plays a key role in cocaine dependence. The long term goal of this project would be to study pharmacological manipulation of the 5-HT1B receptor as a potential molecular target for cocaine dependence.
This study looks to explore the feasibility, sensitivity, validity, and specificity of a Remote Wireless Sensor Network (RWSN) approach to the detection of cocaine use/intoxication in the inpatient human laboratory, as well as in the outpatient setting ("real world"). Lastly, we look to design an algorithm for reliably detecting cocaine use in real-world settings and inference techniques for understanding the relationship between cocaine use and user contexts.
We will develop a procedure for conditioning cue-cocaine associations in human drug users. Next, we will reactivate that learning and intervene pharmacologically to prevent the reconsolidation of cue-drug memories. We hypothesize that a combined behavioral and pharmacological approach will have significant potential for persistently inhibiting relapse.
Examine the interaction between stimulants, such as cocaine and methylphenidate, and impulsivity.
This is a double-blind placebo-controlled clinical trial (n = 200) of varenicline for the treatment of cocaine dependence that utilizes contingency management to promote treatment attendance.
Chronic cocaine administration leads to changes in brain function that persist long after the acute withdrawal phase. The acoustic startle response (ASR) is a well characterized reflexive response to a sudden acoustic stimulus. The ASR is mediated by a simple 3-synapse subcortical circuit; it is modulated in part by brain areas and neurotransmitters associated with cocaine administration. Our initial study and subsequent replication reveals a profound diminution of the ASR in cocaine-dependent subjects after a brief period of abstinence. Our preliminary findings indicate that first degree relatives of cocaine-dependent subjects also have reduced startle compared to healthy controls. The findings of low ASR in rats and humans during cocaine washout and low ASR in family members suggests there may be both a trait and state component of the startle reductions we have reported. The central objectives of this proposal are to dissect this finding with regard to its development and persistence in early and later phases of cocaine abstinence in humans; to ascertain whether startle reduction and its potential normalization during later abstinence is a predictor of clinical course in human subjects with cocaine dependence; and to examine whether startle reduction is, at least in part, a vulnerability trait for the development of cocaine dependence. This latter Aim will be carried out in humans by testing siblings of cocaine-dependent subjects. Cocaine dependence is an enormous public health problem. The significance of this work lies in the potential for the ASR reduction to serve as a reliable, easily repeatable biological measure of cocaine-induced brain changes that may enhance outcome prediction so that tailored treatments may be directed at those patients most vulnerable to relapse, given the restriction of resources for available for substance abuse treatment.
Although a great amount of research has been conducted to resolve cocaine dependence, an effective treatment has yet to be discovered. Topiramate is a drug that was found to be useful in treating alcohol dependence. The purpose of this study is to determine the effectiveness of topiramate in treating cocaine dependent individuals.
The study aims to evaluate the safety and efficacy of modafinil (200 mg/day) over 10 weeks plus a tailored cognitive behavioural therapy program in the treatment of cocaine dependence.
