NCT ID: NCT03603353 Completed - Smoking Cessation Clinical Trials

The ESTxENDS Trial- Substudy on the Effects of Using Electronic Nicotine Delivery Systems (ENDS) on Sleep Quality.

ESTxENDS
Start date: July 16, 2018
Phase: N/A
Study type: Interventional

--> This is a substudy of the main ESTxENDS trial (NCT03589989). Sleep quality outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. The majority of attempts to quit tobacco smoking do not end in success due to unpleasant withdrawal symptoms. One of such symptoms is disturbed sleep. Sleep disturbances are a problem for smokers who are trying to quit. Sleep disturbances results from difficulty falling asleep or frequent arousals after sleep onset, and have negative daytime consequences such as sleepiness and dysphoric mood. Studies indicate that awakenings during night affect the cardiovascular system by providing repetitive bursts of sympathetic nervous system activation, likely contributing to elevated levels of cardiovascular and cerebrovascular morbidity. ENDS with nicotine containing e-liquids may be effective in assisting with tobacco smoking cessation by reducing withdrawal-induced sleep disturbances. This study will therefore test the efficacy of ENDS for cigarette smoking cessation, the safety of ENDS on adverse events and the effect of ENDS on health-related outcomes and exposure to inhaled chemicals. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-month period. Sleep quality will be assessed using the Pittsburgh sleep quality index- questionnaire at baseline and at 6, 12 and 24 months' follow-up.

NCT ID: NCT03603340 Completed - Depression Clinical Trials

The ESTxENDS Trial- Substudy on the Effects of Using Electronic Nicotine Delivery Systems (ENDS) on Depression

ESTxENDS
Start date: July 16, 2018
Phase: N/A
Study type: Interventional

--> This is a substudy of the main ESTxENDS trial (NCT03589989). Depression outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Smoking and depression are strongly associated. Individuals with depression are twice as likely to be smokers than persons without a depression. Studies have shown that attempts to quit tobacco smoking are more likely to fail for individuals with depression than without. Depressive symptoms are common in prolonged nicotine withdrawal and individuals with depression are more nicotine dependent and more likely to suffer depressive symptoms during nicotine withdrawal compared to smokers in the general population. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. ENDS with nicotine containing e-liquids may be effective in assisting with tobacco smoking cessation without suffering depressive symptoms. This study will therefore test the efficacy of ENDS for cigarette smoking cessation, the safety of ENDS on adverse events and the effect of ENDS on health-related outcomes such as depression and exposure to inhaled chemicals. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-month period. Presence and severity of depression will be assessed using the 9-question depression scale from the patient health questionnaire (PHQ-9) at baseline and at 6, 12 and 24 months' follow-up.

NCT ID: NCT03597607 Completed - Quality of Life Clinical Trials

Evaluation of an Intensive Individualized Smoking Cessation Program Delivered by Pharmacists

Start date: September 18, 2018
Phase: N/A
Study type: Interventional

This study aims to look at the efficacy and impact of a pharmacist-led smoking cessation program. It will assess an intensive program and an abbreviated program, with the latter being evaluated for feasibility in community pharmacies. Participants will be in one of two groups: intensive or abbreviated. Smoking abstinence rates, self-efficacy and overall satisfaction will be compared. Additionally, a cost-effectiveness analysis will be executed to determine the feasibility of customized smoking cessation programs in community pharmacies across Newfoundland and Labrador.

NCT ID: NCT03589989 Completed - Smoking Cessation Clinical Trials

The ESTxENDS Trial- Electronic Nicotine Delivery Systems (ENDS/Vaporizer/E-cigarette) as an Aid for Smoking Cessation.

ESTxENDS
Start date: July 16, 2018
Phase: N/A
Study type: Interventional

Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. Only two rigorous randomized controlled trials (RCTs) on the efficacy of ENDS to help smokers quit have been published so far. They have promising, yet inconclusive results, as the number of included participants were small. The safety and potential adverse effects of ENDS are also largely unknown. While the aerosol the users inhale appears safe in laboratory conditions, the difference in exposure to chemicals (such as reduction in exposure to volatile organic compounds) and effects of chemicals on the body (adverse events, improved health-related outcomes and measures of oxidative stress) between smokers who quit (with or without ENDS) and those who use ENDS for a long time have not yet been assessed in an RCT. This study will therefore test the efficacy of ENDS for cigarette smoking cessation, the safety of ENDS on adverse events and the effect of ENDS on health-related outcomes and exposure to inhaled chemicals. The primary hypothesis of this trial is that providing cigarette smokers willing to quit smoking tobacco cigarettes with ENDS leads to a higher rate of smokers who quit cigarette smoking than only smoking cessation counseling with nicotine replacement therapy (NRT), which represents nowadays the standard of care. For this trial, cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. Participants in both groups will be allowed to additionally use nicotine replacement therapy. All participants will be followed over a 6-month period. Smoking cessation counseling will be provided in person at the first clinical visit and then over the phone at the target quit date and again at week 1, 2, 4 and 8 after the target quit date. After 6 months, participants will be asked to come to a final clinical visit.

NCT ID: NCT03586596 Completed - Smoking Cessation Clinical Trials

Mobile Cessation Support for Latino Smokers

Start date: September 1, 2018
Phase: N/A
Study type: Interventional

The primary aim of this study is to examine the efficacy of Decídetexto, an innovative mobile smoking cessation intervention that incorporates two elements: 1) a tablet-based e-Health platform that collects personal smoking-related information to support the development of an individualized quit plan and guides the ensuing text messaging program; and 2) a 12-week text messaging "skills-based counseling" (I.e, behavioral support) program that includes educational information, behavioral strategies, motivational messaging, and pharmacotherapy support driven by information obtained from both the tablet program and the user's text messages. The investigators will evaluate its efficacy relative to a standard care condition that provides high quality printed smoking cessation materials along with referral to telephone quit line counseling. Participants in both groups are given access to free pharmacotherapy via a toll-free study number. Experienced Promotores de Salud (Community Health Workers) will use community and clinic-based outreach to recruit Latino smokers into the study. Participants in both conditions will complete follow-up assessment at the end of treatment (Week 12) and Month 6 (primary outcome). Our hypothesis is that at month 6, smokers in Decídetexto will have significantly higher cotinine-verified 7-day point prevalence abstinence (no cigarettes in the past 7 days) than smokers in the control arm.

NCT ID: NCT03585231 Completed - Smoking Cessation Clinical Trials

Pilot Trial of the First Conversational Agent for Smoking Cessation (QuitBot)

QuitBot
Start date: September 17, 2018
Phase: N/A
Study type: Interventional

Conversational agents (CAs) are computer-powered digital coaches designed to form long-term social-emotional connections with users through conversations. We have developed a CA for cigarette smoking cessation. In a pilot randomized trial (N = 415), we will compare the experimental messaging program (n = 155) with the standard of care national government smoking cessation messaging program (n = 157), and then we will compare immediate (n=51) versus delayed (n=51) access to the the experimental messaging program, to assess 12-week usability, receptivity, and preliminary cessation results in adults in western Washington State and nationally across the US who want to quit smoking.

NCT ID: NCT03583203 Completed - COPD Clinical Trials

Tobacco Intensive Motivational and Estimate Risk

Start date: July 12, 2018
Phase: N/A
Study type: Interventional

Randomized, open label, prospective study with a 12-month follow-up period. The primary objective evaluates the effectiveness of an intensive anti-smoking programme that informs patients of their individual risk of lung damages and the possibilities of prevention. The main measurement will be having given up smoking in month 12, measurement of self-reported abstinence on the 7 previous days and confirmed by a CO-oximeter test< 10 ppm, between the intervention and control group. A total of 9 urban and rural mental health centres will participate in the study. The intervention group will undergo spirometry and presence and the degree of respiratory obstruction will be assessed. Participants will be given individual information to generate a motivational message about the possibilities of prevention and the information will be maintained for three months by sending text messages (SMS) to their mobile phones. The efficacy of the method and the pulmonary damage variables will be evaluated: smoking cessation at the end of follow-up will be confirmed by cooximetry, and the COPD diagnosis and the severity of the staging for disease will be assessed
