INDIANAPOLIS, June 27 /PRNewswire-FirstCall/ -- Eli Lilly and Co (NYSE: LLY) and Boehringer Ingelheim today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMEA) has issued a positive opinion supporting the approval of Cymbalta(R) (duloxetine hydrochloride) for the treatment of Generalised Anxiety Disorder (GAD).
The positive opinion is based upon the results of five clinical studies -- four double-blind placebo-controlled studies and a relapse prevention study -- involving more than 2,000 non-depressed adults with GAD. In each of the four placebo-controlled studies safety and efficacy were assessed. Duloxetine significantly improved core anxiety symptoms (as measured by the Hamilton Anxiety Scale), compared with placebo (p less than or equal to 0.001, p=0.02, p=0.007, p less than or equal to 0.001 respectively) (1,2,3,4) and demonstrated improvement in role functioning, including ability to perform everyday activities in work, home and in social situations.(5,6) In addition, duloxetine significantly decreased the likelihood of relapse in those patients who initially responded to duloxetine and were maintained on treatment for six months compared with those switched to placebo.(7) The most common side effects in these studies included nausea, fatigue, dry mouth, drowsiness, constipation, insomnia, decreased appetite, hyperhidrosis, decreased libido, vomiting, ejaculation delay and erectile dysfunction.
Although global prevalence is not currently known, more than nine million Europeans (8,9) and six million people in Central and South America are estimated to suffer from GAD.(10) Difficult to detect, due to the fact that the condition presents with a variety of symptoms,(11) GAD is characterised by more than simple anxiety. The disorder is diagnosed when patients suffer from excessive anxiety and worry about a number of events and activities (such as performance at work or school) over a sustained period of at least six months.(12)
"If left untreated, symptoms of Generalised Anxiety Disorder may progress to prevent patients from working and operating in daily social situations," said Dr. Christer Allgulander of the Department of Clinical Neuroscience, Karolinska Institutet in Stockholm. "According to population and primary care surveys the majority of people suffering from anxiety, and their physicians, still have unmet needs. This positive opinion on duloxetine creates another effective pharmacotherapy option that will help patients feel better, and help physicians in their aim to improve functioning for those suffering from this debilitating condition."
Duloxetine, a member of a class of drugs commonly referred to as
serotonin and noradrenaline reuptake inhibitors,(13) is already approved to
treat major depressive disorder and diabetic peripheral neuropathic pain.
Duloxetine gained marketing authorisation for the treatment of GAD in
Mexico in 2006 and in the United States in 2007.
Notes to Editors:
About Generalised Anxiety Disorder
Approximately nine million Europeans (8,9) and six million people in Central and South America are estimated to suffer from GAD.(10) Quality of life is affected as symptoms of GAD can include exaggerated worry or chronic anxiety, irritability and poor concentration. Ability to work is often compromised with the manifestation of physical symptoms such as muscle tension, fatigue, sleep disturbance and nausea.(12) The illness tends to be chronic with periods of exacerbation and remission. Patients report that episodes of generalized anxiety disorder are often brought on, or worsened, by stressful life events.(14)
While duloxetine's mechanism of action in humans is not fully known, it is believed to affect both serotonin and norepinephrine/noradrenaline mediated nerve signalling in the brain and the spinal cord. Based on pre-clinical studies, duloxetine is a balanced and potent reuptake inhibitor of serotonin and norepinephrine/noradrenaline. Scientists believe its effect on pain perception is due to increasing the activity of serotonin and norepinephrine in the central nervous system.
Duloxetine is approved for the treatment of depression and diabetic peripheral neuropathic pain, in many countries and is approved in some countries for the treatment of stress urinary incontinence, Major Depressive Disorder and Generalized Anxiety Disorder. Duloxetine is approved only for adults 18 and over. There is a possibility of an increased risk of suicidal thoughts or behaviour in children and young adults treated with antidepressants. Patients should call their doctor right away if they experience worsening depression symptoms, unusual changes in behaviour or thoughts of suicide, especially at the beginning of treatment or after a change in dose.
Patients taking duloxetine may experience dizziness or fainting upon standing. The most common side effects of duloxetine include:
-- For depression: Nausea, dry mouth, headache, insomnia, diarrhea
-- For diabetic peripheral neuropathic pain: Nausea, somnolence (sleepiness), fatigue, headache, dizziness
-- For stress urinary incontinence: Nausea, dry mouth, fatigue
-- For Generalised Anxiety Disorder: Nausea, fatigue, dry mouth, drowsiness, constipation, insomnia, decreased appetite, hyperhidrosis, decreased libido, vomiting, ejaculation delay and erectile dysfunction.
(This is not a complete list of side effects.)
Duloxetine is contraindicated in patients who are allergic to it, who have liver disease resulting in hepatic impairment, who are taking a monoamine oxidase inhibitor (MAOI), fluvoxamine, ciprofloxacin or enoxacine or who have severe kidney disease. The initiation of treatment with duloxetine also is contraindicated in patients with uncontrolled hypertension that could expose them to a potential risk of hypertensive crisis.
