Published Studies Related to Guanfacine

Guanfacine extended-release: in attention deficit hyperactivity disorder. [2010.09.10]
Guanfacine, an alpha(2A)-adrenoceptor agonist, is available in the US as an extended-release (ER) tablet for the treatment of attention deficit hyperactivity disorder (ADHD) in children and adolescents (aged 6-17 years). In two large, randomized, double-blind, placebo-controlled trials of 8 and 9 weeks' duration, guanfacine ER (1-4 mg once daily) was effective in reducing the symptoms of ADHD (hyperactivity, impulsivity and inattention) in children and adolescents...

Effects of guanfacine extended release on oppositional symptoms in children aged 6-12 years with attention-deficit hyperactivity disorder and oppositional symptoms: a randomized, double-blind, placebo-controlled trial. [2010.09.01]
CONCLUSIONS: In this population of children aged 6-12 years with ADHD and the presence of oppositional symptoms, significant reductions in CPRS-R:L oppositional subscale and ADHD-RS-IV total scores were observed with guanfacine XR treatment compared with placebo. Treatment with guanfacine XR at optimized doses was associated with mostly mild or moderate TEAEs. The findings of this study support the efficacy of guanfacine XR in the treatment of children with ADHD and the presence of oppositional symptoms. Clinical Trial Registration Number: NCT00367835.

Guanfacine extended release in children and adolescents with attention-deficit/hyperactivity disorder: a placebo-controlled trial. [2009.02]
CONCLUSIONS:: Guanfacine extended-release was effective in reducing symptoms of ADHD. Adverse events were mild to moderate, did not interfere with improvements in attention, and rarely led to discontinuation.

Clinical Trials Related to Guanfacine

Guanfacine Adjunctive Treatment to Atypical Antipsychotics for Cognitive Dysfunction in Schizophrenia [Active, not recruiting]
Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.

Effect of Guanfacine Extended-Release on Attention Deficit Hyperactivity Disorder (ADHD)-Associated Insomnia [Recruiting]
This study seeks to determine, using special sleep tests (polysomnography and actigraphy) if

guanfacine extended release is able to improve nighttime sleep in children with ADHD -

associated insomnia while improving daytime ADHD symptoms. Male and female children with diagnosed or suspected ADHD with sleep problems (difficulty falling asleep, difficulty staying asleep, or less than expected hours of sleep) will be recruited. After obtaining informed consent and assent (when appropriate) and after discontinuation of excluded medications, children will have evaluations of his or her sleep and evaluations confirming the ADHD diagnosis. Children who successfully pass screening will be enrolled into the double-blind, placebo-controlled, randomized investigation with 50% of participants receiving guanfacine extended release and 50% of participants receiving matching placebo. Using a flexible-dose optimization design based on ADHD symptom improvement and medication tolerability, the dose will be adjusted between 1 to 4 mg over the course of four weeks. At the end of medication adjustment (week 4 or 5), ADHD questionnaires, sleep questionnaires, and sleep tests will be repeated and analyzed. The medication will be weaned over the course of the following 3-10 days.

Guanfacine Treatment for Prefrontal Cognitive Dysfunction in Elderly Subjects [Recruiting]
This proposal aims to determine whether low does of the alpha-2A-adrenoceptor agonist guanfacine can improve deficits in prefrontally-mediated cognitive functions in healthy elderly subjects.

Electrophysiological Effects of Guanfacine Extended Release in Attention Deficit Hyperactivity Disorder (ADHD) [Recruiting]
All subjects with the study will be children (age 6-12) with Attention Deficit Hyperactivity Disorder (ADHD). After baseline assessment confirms the presence of ADHD, children will have an Event related potential (ERP) (a type of electroencephalogram [EEG]) study. After the baseline EEG, children will be randomized to either placebo or GXR for a 4-week, parallel groups trial. During this trial, dosing will be flexibly adjusted according to patient response or presence of side effects. The dosage will range from 1-4 mg. At the end of the four week trial, a follow up ERP study will be obtained.

Guanfacine in Children With Tic Disorders [Recruiting]
The goal of this pilot study is to obtain preliminary information on the tolerability and efficacy of extended release guanfacine (trade name Intuniv) in children with Tourette Disorder (TD, also called Tourette syndrome).
