Cost of start-up activities to implement a community-level opioid overdose reduction intervention in the HEALing Communities Study.

BACKGROUND: Communities That HEAL (CTH) is a novel, data-driven community-engaged intervention designed to reduce opioid overdose deaths by increasing community engagement, adoption of an integrated set of evidence-based practices, and delivering a communications campaign across healthcare, behavioral-health, criminal-legal, and other community-based settings. The implementation of such a complex initiative requires up-front investments of time and other expenditures (i.e., start-up costs). Despite the importance of these start-up costs in investment decisions to stakeholders, they are typically excluded from cost-effectiveness analyses. The objective of this study is to report a detailed analysis of CTH start-up costs pre-intervention implementation and to describe the relevance of these data for stakeholders to determine implementation feasibility. METHODS: This study is guided by the community perspective, reflecting the investments that a real-world community would need to incur to implement the CTH intervention. We adopted an activity-based costing approach, in which resources related to hiring, training, purchasing, and community dashboard creation were identified through macro- and micro-costing techniques from 34 communities with high rates of fatal opioid overdoses, across four states-Kentucky, Massachusetts, New York, and Ohio. Resources were identified and assigned a unit cost using administrative and semi-structured-interview data. All cost estimates were reported in 2019 dollars. RESULTS: State-level average and median start-up cost (representing 8-10 communities per state) were $268,657 and $175,683, respectively. Hiring and training represented 40%, equipment and infrastructure costs represented 24%, and dashboard creation represented 36% of the total average start-up cost. Comparatively, hiring and training represented 49%, purchasing costs represented 18%, and dashboard creation represented 34% of the total median start-up cost. CONCLUSION: We identified three distinct CTH hiring models that affected start-up costs: hospital-academic (Massachusetts), university-academic (Kentucky and Ohio), and community-leveraged (New York). Hiring, training, and purchasing start-up costs were lowest in New York due to existing local infrastructure. Community-based implementation similar to the New York model may have lower start-up costs due to leveraging of existing infrastructure, relationships, and support from local health departments.

IUPHAR Review: New strategies for medications to treat substance use disorders.

Substance use disorders (SUDs) and drug overdose are a public health emergency and safe and effective treatments are urgently needed. Developing new medications to treat them is expensive, time-consuming, and the probability of a compound progressing to clinical trials and obtaining FDA-approval is low. The small number of FDA-approved medications for SUDs reflects the low interest of pharmaceutical companies to invest in this area due to market forces, characteristics of the population (e.g., stigma, and socio-economic and legal disadvantages), and the high bar regulatory agencies set for new medication approval. In consequence, most research on medications is funded by government agencies, such as the National Institute on Drug Abuse (NIDA). Multiple scientific opportunities are emerging that can accelerate the discovery and development of new medications for SUDs. These include fast and efficient tools to screen new molecules, discover new medication targets, use of big data to explore large clinical data sets and artificial intelligence (AI) applications to make predictions, and precision medicine tools to individualize and optimize treatments. This review provides a general description of these new research strategies for the development of medications to treat SUDs with emphasis on the gaps and scientific opportunities. It includes a brief overview of the rising public health toll of SUDs; the justification, challenges, and opportunities to develop new medications; and a discussion of medications and treatment endpoints that are being evaluated with support from NIDA.

Evaluation of the New England Office Based Addiction Treatment ECHO: A Tool for Strengthening the Addiction Workforce.

INTRODUCTION: Reducing substance-related morbidity requires an educated and well-supported workforce. The New England Office Based Addiction Treatment Extension for Community Healthcare Outcomes (NE OBAT ECHO) began in 2019 to support community-based addiction care teams through virtual mentoring and case-based learning. We sought to characterize the program's impact on the knowledge and attitudes of NE OBAT ECHO participants. METHODS: We conducted an 18-month prospective evaluation of the NE OBAT ECHO. Participants registered for 1 of 2 successive ECHO clinics. Each 5-month clinic included ten 1.5-hour sessions involving brief didactic lectures and de-identified patient case presentations. Participants completed surveys at Month-0, -6, -12, and -18 to assess attitudes about working with patients who use drugs and evidence based practices (EBPs), stigma toward people who use drugs, and addiction treatment knowledge. We compared outcomes using 2 approaches: (i) between-groups, which involved comparing the first intervention group to the delayed intervention (comparison) group, and (ii) within-groups, which involved comparing outcomes at different time points for all participants. In the within-group approach, each participant acted as their own control. RESULTS: Seventy-six health professionals participated in the NE OBAT ECHO, representing various roles in addiction care teams. Approximately half (47% [36/76]) practiced primary care, internal, or family medicine. The first intervention group reported improved job satisfaction and openness toward EBPs compared to the delayed intervention group. Within-group analyses revealed that ECHO participation was associated with increased positive perceptions of role adequacy, support, legitimacy, and satisfaction 6 months following program completion. No changes were identified in willingness to adopt EBPs or treatment knowledge. Stigma toward people who use drugs was persistent in both groups across time points. CONCLUSIONS: NE OBAT ECHO may have improved participants' confidence and satisfaction providing addiction care. ECHO is likely an effective educational tool for expanding the capacity of the addiction workforce.

Economic benefits of substance use disorder treatment: A systematic literature review of economic evaluation studies from 2003 to 2021.

INTRODUCTION: The economic burden of substance use disorder (SUD) is significant, comprising costs of health care and social services, criminal justice resources, loss of productivity, and premature mortality. This study assembles and synthesizes two decades of evidence describing the benefits of SUD treatment across five main outcome domains; 1) health care utilization; 2) self-reported criminal activity by offense type; 3) criminal justice involvement collected from administrative records or self-reported; 4) productivity assessed through working hours or wages earned; and 5) social services (e.g., a day spent in transitional housing). METHODS: This review included studies if they reported the monetary value of the intervention outcomes, most commonly through a cost-benefit or cost-effectiveness framework. The search included studies from 2003 to the present day as of this writing (up to October 15, 2021). Summary cost estimates were adjusted using the US Consumer Price Index (CPI) to reflect the 12-month benefits per client in USD 2021. We followed the PRISMA methodology for study selection and assessed quality using the Checklist for Health Economic Evaluation Reporting Standards (CHEERS). RESULTS: The databases yielded 729 studies after removing duplicates, and we ultimately selected 12 for review. Studies varied widely regarding analytical approaches, time horizons, outcome domains, and other methodological factors. Among the ten studies that found positive economic benefits, reductions in criminal activity or criminal justice costs represented the largest or second largest component of these benefits (range $621 to $193,440 per client). CONCLUSIONS: Consistent with previous findings, a reduction in criminal activity costs is driven by the relatively high societal cost per criminal offense, notably for violent crimes, such as aggravated assault and rape/sexual assault. Accepting the economic rationale for increased investment in SUD interventions will require recognizing that more benefits accrue to individuals by avoiding being victims of a crime than to governments through budget offsets resulting from savings in non-SUD program expenses. Future studies should explore individually tailored interventions to optimize care management, which may yield unexpected economic benefits to services utilization, and criminal activity data to estimate economic benefits across a broad range of interventions.

Budget impact tool for the incorporation of medications for opioid use disorder into jail/prison facilities.

BACKGROUND: Given the personal and public consequences of untreated/undertreated OUD among persons involved in the justice system, an increasing number of jails and prisons are incorporating medication for opioid use disorder (MOUD) into their system. Estimating the costs of implementing and sustaining a particular MOUD program is vital to detention facilities, which typically face modest, fixed health care budgets. We developed a customizable budget impact tool to estimate the implementation and sustainment costs of numerous MOUD delivery models for detention facilities. METHODS: The aim is to describe the tool and present an application of a hypothetical MOUD model. The tool is populated with resources required to implement and sustain various MOUD models in detention facilities. We identified resources via micro-costing techniques alongside randomized clinical trials. The resource-costing method is used to assign values to resources. Resources/costs are categorized as (a) fixed, (b) time-dependent, and (c) variable. Implementation costs include (a), (b), and (c) over a specified timeframe. Sustainment costs include (b) and (c). The MOUD model example entails offering all three FDA-approved medications, with methadone and buprenorphine provided by vendors, and naltrexone by the jail/prison facility. RESULTS: Fixed resources/costs are incurred only once, including accreditation fees and trainings. Time-dependent resources/costs are recurring, but fixed over a given time-period; e.g., medication delivery and staff meetings. Variable resources/costs are those that are a direct function of the number of persons treated, such as the medication provided to each patient. Using nationally representative prices, we estimated fixed/sustainment costs to be $2919/patient, over 1 year. This article estimates annual sustainment costs to be $2885/patient. CONCLUSION: The tool will serve as a valuable asset to jail/prison leadership, policymakers, and other stakeholders interested in identifying/estimating the resources and costs associated with alternative MOUD delivery models, from the planning stages through sustainment.

Casiopeinas® third generation, with indomethacin: synthesis, characterization, DFT studies, antiproliferative activity, and nanoencapsulation.

Seven new Casiopeinas® were synthesized and properly characterized. These novel compounds have a general formula [Cu(N-N)(Indo)]NO3, where Indo is deprotonated indomethacin and N-N is either bipyridine or phenanthroline with some methyl-substituted derivatives, belonging to the third generation of Casiopeinas®. Spectroscopic characterization suggests a square-based pyramid geometry and voltammetry experiments indicate that the redox potential is strongly dependent on the N-N ligand. All the presented compounds show high cytotoxic efficiency, and most of them exhibit higher efficacy compared to the well-known cisplatin drug and acetylacetonate analogs of the first generation. Computational calculations show that antiproliferative behavior can be directly related to the volume of the molecules. Besides, a chitosan (CS)-polyacrylamide (PNIPAAm) nanogel was synthesized and characterized to examine the encapsulation and release properties of the [Cu(4,7-dimethyl-1,10-phenanthroline)(Indo)]NO3 compound. The results show good encapsulation performance in acidic conditions and a higher kinetic drug release in acidic media than at neutral pH. This result can be described by the Peppas-Sahlin model and indicates a release mechanism predominantly by Fick diffusion.

Health economic analyses of the justice community opioid innovation network (JCOIN).

The Justice Community Opioid Innovation Network (JCOIN) will generate real-world evidence to address the unique needs of people with opioid use disorder (OUD) in justice settings. Evidence regarding the economic value of OUD interventions in justice populations is limited. Moreover, the variation in economic study designs is a barrier to defining specific interventions as broadly cost-effective. The JCOIN Health Economics Analytic Team (HEAT) has worked closely with the Measures Committee to incorporate common economic measures and instruments across JCOIN studies, which will: a) ensure rigorous economic evaluations within each trial; b) enhance comparability of findings across studies; and c) allow for cross-study analyses of trials with similar designs/settings (e.g., pre-reentry MOUD), to assess questions beyond the scope of a single study, while controlling for and evaluating the effect of intervention-, organizational-, and population-level characteristics. We describe shared trial characteristics relevant to the economic evaluations, and discuss potential cross-study economic analyses.

The state of clinical outcome assessments for cannabis use disorder clinical trials: A review and research agenda.

There is considerable variability in the use of outcome measures in clinical trials for cannabis use disorder (CUD), and a lack of consensus regarding optimal outcomes may have hindered development and approval of new pharmacotherapies. The goal of this paper is to summarize an evaluation of assessment measures and clinical endpoints for CUD clinical trials, and propose a research agenda and priorities to improve CUD clinical outcome assessments. The primary recommendation is that sustained abstinence from cannabis should not be considered the primary outcome for all CUD clinical trials as it has multiple limitations. However, there are multiple challenges to the development of a reliable and valid indicator of cannabis reduction, including the lack of a standard unit of measure for the various forms of cannabis and products and the limitations of currently available biological and self-report assessments. Development of a core toolkit of assessments is needed to both allow flexibility for study design, while facilitating interpretation of outcomes across trials. Four primary agenda items for future research are identified to expedite development of improved clinical outcome assessments for this toolkit: (1) determine whether minimally invasive biologic assays could identify an acute level of cannabis use associated with psychomotor impairment or other cannabis-related harms; (2) create an indicator of quantity of cannabis use that is consistent across product types; (3) examine the presence of cannabis-specific functional outcomes; and (4) identify an optimal duration to assess changes in CUD diagnostic criteria.

Craving and opioid use disorder: A scoping review.

INTRODUCTION: The subjective experience of drug craving is a prominent and common clinical phenomenon for many individuals diagnosed with opioid use disorder (OUD), and could be a valuable clinical endpoint in medication development studies. The purpose of this scoping review is to provide an overview and critical analysis of opioid craving assessments located in the published literature examining OUD. METHOD: Studies were identified through a search of PubMed, Embase, and PsychInfo databases and included for review if opioid craving was the focus and participants were diagnosed with or in treatment for OUD. RESULTS: Fifteen opioid craving assessment instruments were identified across the 87 studies included for review. The most common were the Visual Analog Scale (VAS, 41 studies), Desires for Drug Questionnaire (DDQ, 12 studies), Heroin Craving Questionnaire (HCQ, 10 studies), and Obsessive-Compulsive Drug Use Scale (OCDUS, 10 studies). Craving assessments varied considerably in their format, content, time frame, and underlying subscales, and only 6 of 15 had been psychometrically evaluated. DISCUSSION: This review identified a variety of opioid craving assessments, but few had been evaluated for their psychometric properties making it difficult to ascertain whether craving is being assessed optimally in studies of OUD. Thus, the development of a reliable and valid opioid craving assessment would be worthwhile and could be guided by recently published Food and Drug Administration Clinical Outcome Assessment (COA) guidelines. Importantly, a COA focused on opioid craving could be a valuable addition to research studies designed to evaluate novel treatments for OUD.

A Survey of Payer Perspectives on Cannabis Use Disorder.

BACKGROUND: Cannabis use disorder (CUD) as described/defined in DSM 5, is characterized by impaired control of marijuana use and related personal, health, and legal consequences. CUD is a serious public health problem, affecting nearly 6 million individuals in the United States. There are no FDA approved medications to treat this disorder. The lack of available treatment options contributes to uncertainties by drug sponsors about formulary and reimbursement decision-making for CUD pharmacotherapies. OBJECTIVE: To addresses this gap by presenting the first findings on managed care payers' perceptions of CUD treatments and clinical trial end points. METHODS: An online survey was conducted with 50 payers from managed care organizations. The survey inquired about perceptions of unmet need in CUD treatment, relevant clinical trial end points, disease knowledge, and likelihood of review of new pharmacotherapies. RESULTS: The majority of payers (62%) reported that they were at least moderately familiar with CUD treatment end points. Most (80%) rated the unmet need for new pharmacotherapies for CUD as at least moderately important. Payers rated the most important end points for clinical trials as abstinence and decreased resource utilization. Most participants said an FDA approved CUD treatment would be formally reviewed by payers within 6 months (58%) or a year (36%). CONCLUSIONS: Based on these findings, payers see an unmet need for CUD treatment. Furthermore, FDA-approved pharmacotherapies for CUD will likely be reviewed quickly by payers, especially if data are provided on the likelihood of achieving abstinence and reduced resource utilization.

Biomedical ethics and clinical oversight in multisite observational neuroimaging studies with children and adolescents: The ABCD experience.

Observational neuroimaging studies with children and adolescents may identify neurological anomalies and other clinically relevant findings. Planning for the management of this information involves ethical considerations that may influence informed consent, confidentiality, and communication with participants about assessment results. Biomedical ethics principles include respect for autonomy, beneficence, non-maleficence, and justice. Each project presents unique challenges. The Adolescent Brain and Cognitive Development study (ABCD) collaborators have systematically developed recommendations with written guidelines for identifying and responding to potential risks that adhere to biomedical ethics principles. To illustrate, we will review the ABCD approach to three areas: (1) hazardous substance use; (2) neurological anomalies; and (3) imminent potential for self-harm or harm to others. Each ABCD site is responsible for implementing procedures consistent with these guidelines in accordance with their Institutional Review Board approved protocols, state regulations, and local resources. To assure that each site has related plans and resources in place, site emergency procedures manuals have been developed, documented and reviewed for adherence to ABCD guidelines. This article will describe the principles and process used to develop these ABCD bioethics and medical oversight guidelines, the concerns and options considered, and the resulting approaches advised to sites.

[Comparison of mortality by femur fracture versus hip fracture in elderly patients in a period of five years]. / Comparación de mortalidad por fractura de fémur frente a fractura de cadera en ancianos en un periodo de cinco años.

BACKGROUND: Fractures in the elderly population are an economic, social and medical challenge. Not much is known about fractures in this population, which makes difficult the selection of an appropriate treatment. Hip fractures (HF) increase the risk of death and morbidity. Patients with midshaft femur fracture (MFF) have less morbidity and risk of death. The objective was to compare HF and MFF's survival. METHODS: Observational analytic study. The Hospital General de México database was used to gather patients aged 65 to 94 years with HF and MFF from 2010 to 2014. Patients had an heterogeneous follow-up and their cognitive status was not considered; we had a total of 146 patients. Follow-up was made through phone call. RESULTS: Kaplan-Meier estimate was used to assess survival. We compared survival depending on type of fracture and found no statistically significant difference (p = 0.97). On sub-analysis, we compared type of fracture on male gender (p = 0.21) and female gender (p = 0.316) and found no statistically significant difference on survival. This differs from what has been reported. It was used t test to evaluate survival in months, according to male (39.61 ± 19.1) and female (36.58 ± 23.19) gender; this showed a significant difference in both groups (p = 0.037). CONCLUSIONS: In the presence of fractures, we must consider gender when estimating survival on patients with hip or midshaft femur fracture.

INTRODUCCIÓN: las fracturas en los ancianos son un desafío económico, social y médico, de las cuales se desconoce mucho, lo cual dificulta la selección de un tratamiento adecuado. Las fracturas de cadera (FC) incrementan el riesgo de muerte y morbilidad. Los pacientes con fractura de diáfisis femoral (FDF) tienen menos morbilidad y riesgo de muerte. El objetivo fue comparar las FC y la supervivencia de la FDF. Métodos: estudio observacional analítico. Se usó la base de datos del Hospital General de México para recolectar pacientes de 65 a 94 años de edad con FC y FDF del 2010 al 2014. Los pacientes tenían un seguimiento heterogéneo y no se consideraba el estado cognitivo; fueron un total de 146. El seguimiento se hizo por medio de llamada telefónica. RESULTADOS: se usó la estimación de Kaplan-Meier para calcular la supervivencia. Se comparó la supervivencia dependiendo del tipo de fractura y no se encontró diferencia estadísticamente significativa (p = 0.97). En el subanálisis, se comparó el tipo de fractura en el sexo masculino (p = 0.21) y el sexo femenino (p = 0.316) y no hubo diferencias estadísticamente significativas en la supervivencia. Esto difiere de los hallazgos de la literatura. Se utilizó la prueba t para evaluar la supervivencia en meses según el sexo masculino (39.61 ± 19.1) y femenino (36.58 ± 23.19), lo que demuestra una diferencia significativa en ambos grupos (p = 0.037). Conclusión: ante la presencia de fracturas, debemos considerar el género para estimar la supervivencia en pacientes con FC o FDF.7.

Measures That Identify Prescription Medication Misuse, Abuse, and Related Events in Clinical Trials: ACTTION Critique and Recommended Considerations.

Accurate assessment of inappropriate medication use events (ie, misuse, abuse, and related events) occurring in clinical trials is an important component in evaluating a medication's abuse potential. A meeting was convened to review all instruments measuring such events in clinical trials according to previously published standardized terminology and definitions. Only 2 approaches have been reported that are specifically designed to identify and classify misuse, abuse, and related events occurring in clinical trials, rather than to measure an individual's risk of using a medication inappropriately: the Self-Reported Misuse, Abuse, and Diversion (SR-MAD) instrument and the Misuse, Abuse, and Diversion Drug Event Reporting System (MADDERS). The conceptual basis, strengths, and limitations of these methods are discussed. To our knowledge, MADDERS is the only system available to comprehensively evaluate inappropriate medication use events prospectively to determine the underlying intent. MADDERS can also be applied retrospectively to completed trial data. SR-MAD can be used prospectively; additional development may be required to standardize its implementation and fully appraise the intent of inappropriate use events. Additional research is needed to further demonstrate the validity and utility of MADDERS as well as SR-MAD. PERSPECTIVE: Identifying a medication's abuse potential requires assessing inappropriate medication use events in clinical trials on the basis of a standardized event classification system. The strengths and limitations of the 2 published methods designed to evaluate inappropriate medication use events are reviewed, with recommended considerations for further development and current implementation.

Measures of outcome for stimulant trials: ACTTION recommendations and research agenda.

BACKGROUND: The development and approval of an efficacious pharmacotherapy for stimulant use disorders has been limited by the lack of a meaningful indicator of treatment success, other than sustained abstinence. METHODS: In March, 2015, a meeting sponsored by Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) was convened to discuss the current state of the evidence regarding meaningful outcome measures in clinical trials for stimulant use disorders. Attendees included members of academia, funding and regulatory agencies, pharmaceutical companies, and healthcare organizations. The goal was to establish a research agenda for the development of a meaningful outcome measure that may be used as an endpoint in clinical trials for stimulant use disorders. RESULTS AND CONCLUSIONS: Based on guidelines for the selection of clinical trial endpoints, the lessons learned from prior addiction clinical trials, and the process that led to identification of a meaningful indicator of treatment success for alcohol use disorders, several recommendations for future research were generated. These include a focus on the validation of patient reported outcome measures of functioning, the exploration of patterns of stimulant abstinence that may be associated with physical and/or psychosocial benefits, the role of urine testing for validating self-reported measures of stimulant abstinence, and the operational definitions for reduction-based measures in terms of frequency rather than quantity of stimulant use. These recommendations may be useful for secondary analyses of clinical trial data, and in the design of future clinical trials that may help establish a meaningful indicator of treatment success.

Optical and Electrical Properties of TTF-MPcs (M = Cu, Zn) Interfaces for Optoelectronic Applications.

Sandwich structures were fabricated by a vacuum deposition method using MPc (M = Cu, Zn), with a Tetrathiafulvalene (TTF) derivative, and Indium Tin Oxide (ITO) and aluminum electrodes. The structure and morphology of the deposited films were studied by IR spectroscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The absorption spectra of TTF derivative-MPc (M = Cu, Zn) thin films deposited at room temperature were recorded in the spectral range 200-1000 nm. The optical band gap of the thin films was determined from the (αhν)(1/2) vs. hν plot. The direct-current (DC) electrical properties of the glass/ITO/TTFderiv-MPc (M = Cu, Zn)/Al structures were also investigated. Changes in conductivity of the derivative-TTF-enriched Pc compounds suggest the formation of alternative paths for carrier conduction. At low voltages, forward current density obeys an ohmic I-V relationship; at higher voltages, conduction is mostly due to a space-charge-limited conduction (SCLC) mechanism.

Randomized Trial of Reduced-Nicotine Standards for Cigarettes.

BACKGROUND: The Food and Drug Administration can set standards that reduce the nicotine content of cigarettes. METHODS: We conducted a double-blind, parallel, randomized clinical trial between June 2013 and July 2014 at 10 sites. Eligibility criteria included an age of 18 years or older, smoking of five or more cigarettes per day, and no current interest in quitting smoking. Participants were randomly assigned to smoke for 6 weeks either their usual brand of cigarettes or one of six types of investigational cigarettes, provided free. The investigational cigarettes had nicotine content ranging from 15.8 mg per gram of tobacco (typical of commercial brands) to 0.4 mg per gram. The primary outcome was the number of cigarettes smoked per day during week 6. RESULTS: A total of 840 participants underwent randomization, and 780 completed the 6-week study. During week 6, the average number of cigarettes smoked per day was lower for participants randomly assigned to cigarettes containing 2.4, 1.3, or 0.4 mg of nicotine per gram of tobacco (16.5, 16.3, and 14.9 cigarettes, respectively) than for participants randomly assigned to their usual brand or to cigarettes containing 15.8 mg per gram (22.2 and 21.3 cigarettes, respectively; P<0.001). Participants assigned to cigarettes with 5.2 mg per gram smoked an average of 20.8 cigarettes per day, which did not differ significantly from the average number among those who smoked control cigarettes. Cigarettes with lower nicotine content, as compared with control cigarettes, reduced exposure to and dependence on nicotine, as well as craving during abstinence from smoking, without significantly increasing the expired carbon monoxide level or total puff volume, suggesting minimal compensation. Adverse events were generally mild and similar among groups. CONCLUSIONS: In this 6-week study, reduced-nicotine cigarettes versus standard-nicotine cigarettes reduced nicotine exposure and dependence and the number of cigarettes smoked.

Classification and definition of misuse, abuse, and related events in clinical trials: ACTTION systematic review and recommendations.

As the nontherapeutic use of prescription medications escalates, serious associated consequences have also increased. This makes it essential to estimate misuse, abuse, and related events (MAREs) in the development and postmarketing adverse event surveillance and monitoring of prescription drugs accurately. However, classifications and definitions to describe prescription drug MAREs differ depending on the purpose of the classification system, may apply to single events or ongoing patterns of inappropriate use, and are not standardized or systematically employed, thereby complicating the ability to assess MARE occurrence adequately. In a systematic review of existing prescription drug MARE terminology and definitions from consensus efforts, review articles, and major institutions and agencies, MARE terms were often defined inconsistently or idiosyncratically, or had definitions that overlapped with other MARE terms. The Analgesic, Anesthetic, and Addiction Clinical Trials, Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership convened an expert panel to develop mutually exclusive and exhaustive consensus classifications and definitions of MAREs occurring in clinical trials of analgesic medications to increase accuracy and consistency in characterizing their occurrence and prevalence in clinical trials. The proposed ACTTION classifications and definitions are designed as a first step in a system to adjudicate MAREs that occur in analgesic clinical trials and postmarketing adverse event surveillance and monitoring, which can be used in conjunction with other methods of assessing a treatment's abuse potential.

Advances in the development of biologics to treat drug addictions and overdose.

Drug addictions are complex disorders that require multiple approaches, including the use of pharmacotherapies. Currently, these therapies are based on "small" molecules or chemicals that penetrate the blood-brain barrier, reach the brain, and produce their effects on neurotransmitter systems. Unfortunately, they often do not have the desired efficacy or may cause undesirable side effects, especially at the central nervous system (CNS) level. A novel approach is the use of biologics to treat drug addictions. Biologics are usually complex and "large" molecules, which do not cross the blood-brain barrier and, thus, have no CNS effects. In principle, it appears that the efficacy of biologics to treat drug addiction is by preventing the access of the drug of abuse to the brain, preventing the activation of brain reward systems, and eventually producing the extinction of addiction. Biologic therapeutics includes immunotherapies, such as vaccines or antibodies, as well as enzymes. New products as well as new and more efficient methods of production, are offering vast opportunities to advance the discovery and development of biologics to treat addictions as well as drug overdose. These products include new vaccines with greater specificity and ability to produce antibodies, new methods and techniques to produce vaccines and antibodies, as well as new enzymes with high efficiency to metabolize cocaine. The purpose of the article is to provide a general overview of the development of biologics for the treatment of drug addictions and overdose.

Avances en el desarrollo de productos biológicos para el tratamiento de la adicción a las drogas y las sobredosis / Advances in the Development of Biologics to Treat Drug Addictions and Overdose

La adicción a las drogas es un trastorno complejo que requiere diversos abordajes, entre los que está el uso de tratamientos farmacológicos. Actualmente, estas terapias se basan en "pequeñas" moléculas o sustancias químicas que atraviesan la barrera hematoencefálica y actúan sobre los neurotransmisores. Desafortunadamente, con frecuencia no tienen la eficacia deseada o pueden causar efectos secundarios no deseados, que afectan especialmente el sistema nervioso central(SNC). Un enfoque novedoso es el uso de productos biológicos para el tratamiento de la adicción a las drogas. Los productos biológicos son generalmente moléculas complejas y "grandes", que no atraviesan la barrera hematoencefálica y por tanto, no tienen efectos sobre el SNC. En principio, parece que estos productos impiden el acceso de las drogas de abuso al cerebro, con lo cual se previene la activación de los sistemas de recompensa del cerebro y, en consecuencia, se produce la extinción de la adicción. Los tratamientos biológicos incluyen inmunoterapias, tales como las vacunas o los anticuerpos, así como también las enzimas. La aparición de nuevos productos, así como métodos de producción más modernos y eficientes, está posibilitando enormes oportunidades para avanzar en el descubrimiento y desarrollo de productos biológicos para el tratamiento de las adicciones, así como también de las sobredosis por drogas. Estos productos incluyen nuevas vacunas con mayor especificidad y capacidad de producir anticuerpos, nuevos métodos y técnicas para producir vacunas y anticuerpos, y nuevas enzimas butyrylcholinesterases con una alta eficiencia para metabolizar cocaína. El propósito de este artículo es proporcionar una visión general del desarrollo de productos biológicos para el tratamiento de adicción a las drogas y la sobredosis(AU)
