Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
AZD1446 compared to placebo, improves ADHD core symptoms in adult non-users and users of nicotine products after 2 weeks of treatment as measured by the Conners' Adult ADHD Rating Scale-Investigator Rated (CAARS-INV) Total ADHD Symptoms score (18 item)
Time Frame: The CAARS-INV will be administered once at each of the following visits: Visit 1; Visit 2; Visits 3,4,5; Visit 7; Visits 8, 9, 10; Visit 12; and Visits 13, 14 and 15
The CAARS-INV will be administered once at each of the following visits: Visit 1; Visit 2; Visits 3,4,5; Visit 7; Visits 8, 9, 10; Visit 12; and Visits 13, 14 and 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To evaluate the effect of AZD1446 treatment compared to placebo on ADHD symptoms as derived from the 30 item Conners' Adult ADHD Rating Scale-Investigator Rated (CAARS-INV) scoring
Time Frame: Visit 1; Visit 2; Visits 3,4,5; Visit 7; Visits 8, 9, 10; Visit 12; and Visits 13, 14 and 15

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
