About this study

Official title: An Open Pilot Study of Varenicline (Chantix) in Adult Smokers With Attention Deficit Hyperactivity Disorder (ADHD): Effects on ADHD and Cigarette Smoking

The purpose of this research study is to learn about the efficacy of a medication called varenicline (Chantix) in treating ADHD in adults and in reducing cigarette smoking in adults with ADHD. The investigators hypothesize that ADHD symptomatology in adults with ADHD will be improved with varenicline treatment. The investigators also hypothesize that varenicline treatment will result in significant reductions in cigarette smoking. Another objective of this study is to more fully evaluate the response and tolerability to varenicline in this group of cigarette smoking adults with ADHD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Varenicline (Chantix)Drug

    Also called Chantix(varenicline) is a smoking cessation medicine.

    Upon completion of screening procedures and meeting eligibility criteria, subjects will begin taking varenicline daily until Week 6 of the study. At Week 6 they will discontinue varenicline and return one week later for their final study visit to assess return of ADHD symptomatology. Subjects will start on 0.5 mg of varenicline per day for the first week of treatment. The dose will be increased to 0.5 mg twice a day at the end of week 1 visit, and then increased to 1 mg twice a day at the end of week 2 visit, to remain at this dose until the week 6 visit. At week 6, all subjects will be openly discontinued from varenicline, to return to the office the following week for re-assessment one week off the medication. If significant adverse effects (AE) occur, the daily dose may be reduced by 0.5 to 1 mg. At subsequent visits, a higher dose may be resumed if tolerated. Maximum dose will be 2 mg daily.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The DSM-IV Based Adult ADHD Investigator Symptom Rating Scale (AISRS)

    The AISRS is an 18-item questionnaire administered by the clinician assessing each of the individual DSM-IV symptoms of ADHD. Each symptom is rated on a scale of severity from 0 (none) to 3 (severe), and the 18 symptom questions are summed to calculate a total score. The minimum total score is a 0, while the maximum total score is a 54.

    Measured: Weekly for 7 weeks

  2. Time Line Follow Back of Cigarette Smoking

    The reduction in cigarette smoking, defined as the change from baseline on the amount of cigarettes per day smoked (cpd), using the time-line follow back method. This method involves asking subjects to retrospectively estimate their cigarette use 7 days to 2 years prior to the interview date.

    Measured: Weekly for 7 weeks

Secondary outcomes (5)
  1. Exhaled CO Levels

    At baseline and all weekly study visits,exhaled carbon monoxide (CO) levels were read.

    Measured: Weekly over 7 weeks

  2. Rates of Smoking Cessation

    Varenicline has efficacy in smoking sensation; therefore smoking cessation was measured at baseline and at all study visits.

    Measured: Weekly for 7 weeks

  3. ADHD Clinical Global Impressions Scale Improvement (CGI-I) and Severity (CGI-S)

    The Clinical Global Impression Scale of ADHD for Improvement and Severity assess overall severity and change in severity of ADHD. The CGI-I scale is rated from 1 to 7 (1=very much improved; 7=very much worse). The CGI-S is rated from 1 to 7 as well (1=not ill; 7=extremely ill).

    Measured: Weekly for 7 weeks

  4. Vital Signs

    Vital signs were collected at each study visit, including height, weight, blood pressure, and heart rate.

    Measured: Weekly for 7 weeks

  5. Spontaneous Reports of Adverse Effects

    Reports of adverse events were completed at baseline and weekly visits throughout the trial.

    Measured: Weekly for 7 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Varenicline (Chantix) in people with Attention Deficit/Hyperactivity Disorder and Smoking Cessation, run by Massachusetts General Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Sep 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The DSM-IV Based Adult ADHD Investigator Symptom Rating Scale (AISRS) (time frame: Weekly for 7 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2017.
