Fewer Patients on Treatment Experienced a New Episode INDIANAPOLIS,
Dec. 10 /PRNewswire-FirstCall/ -- New data suggest that Cymbalta
(duloxetine HCl) 60 mg to 120 mg once daily delayed the onset of a
new episode of depression in patients who had previously responded
to the medication and who had recurrent depressive disorder,
defined in the study as those patients who experienced at least
three depressive episodes in the previous five years, compared with
placebo (p < .001). Results from the 52- week maintenance phase
of the longest controlled duloxetine study completed to date were
presented at a meeting of a major scientific society today.
Additionally, patients who were treated with duloxetine were less
likely (p < .001) to experience a new episode of depression than
those who received placebo (recurrence rates were 14.4 percent vs.
33.1 percent, respectively). Previous research has shown that up to
85 percent of patients with depression will experience depressive
recurrences.(i) The number of episodes,(ii) their duration(iii) and
the presence of lingering depressive symptoms increase the risk of
recurrence, or future episodes of depression.(iv) In the
placebo-controlled maintenance phase of the study that followed
initial open-label acute and continuation treatment phases, the
most common adverse events (those occurring in at least 5 percent
of patients in any treatment group) were headache, insomnia,
dizziness, fatigue, back pain, common cold and flu. Additional
Study Findings -- Time to worsening of depressive symptoms was
significantly longer (p = .006) in the duloxetine-treated group
compared with the placebo- treated group. This was defined as a 50
percent increase from baseline on the 17-item Hamilton Rating Scale
for Depression (HAMD17) total score and a Clinical Global
Impressions of Severity (CGI-S) score of 3 or more at anytime
during the maintenance phase. -- Patients taking duloxetine
experienced less worsening in symptom severity during the 52-week
maintenance phase as measured by efficacy measures including the
HAMD17 total score and subscales, the CGI-S and the Patient's
Global Impression of Improvement (PGI-I) scales, compared with
those taking placebo (p-values < .01). -- Patients taking
duloxetine experienced a similar worsening in somatic symptom
severity during the 52-week maintenance phase as measured by Visual
Analog Scales (VAS) for pain and the Symptom Questionnaire- Somatic
Subscale (SQ-SS), compared with those taking placebo (p-values >
.05). -- The proportion of duloxetine-treated patients who
discontinued the study due to adverse events during the acute,
continuation and maintenance phases was 6.6 percent, 6.1 percent
and 4.1 percent, respectively. The following were the most common
treatment-emergent adverse events: - Acute phase: nausea, headache,
dry mouth and excessive sweating -- In addition, there was one
person who did not complete the acute phase due to a completed
suicide, which was determined by study investigators not to be
attributed to treatment. - Continuation phase: headache, common
cold and excessive sweating - Maintenance phase: headache, back
pain and common cold Methods The 52-week maintenance phase was
preceded by up to 34-weeks of open-label treatment with duloxetine
60-120 mg once daily. Of the 514 patients initially entered into
the study, 288 patients met response criteria at the end of up to
34 weeks treatment and were entered into the 52-week, double-blind,
maintenance phase of the study. During the maintenance phase,
patients were randomly assigned to receive either duloxetine at the
dose to which they had previously responded, or placebo. The
primary endpoint of the study was time to recurrence of a major
depressive episode during 52 weeks of maintenance treatment, as
assessed by any of the following recurrence criteria: a CGI-S score
greater than or equal to 4 and meeting DSM-IV criteria for major
depressive disorder; three consecutive visits meeting re-emergence
criteria or 10 total re-emergence visits; or study discontinuation
due to lack of efficacy. Secondary measures included the HAMD17
total score and subscales, CGI-S and PGI-I scales, SQ-SS and VAS
for pain. Safety and tolerability were assessed via analysis of
treatment-emergent adverse events, vital signs, weight, ASEX for
sexual functioning and laboratory measures. The primary study
manuscript has already been submitted for review with a view to
publication in a peer-reviewed medical journal. About Duloxetine
Duloxetine is approved in the United States for the acute and
maintenance treatment of major depressive disorder, the acute
treatment of generalized anxiety disorder, and the management of
diabetic peripheral neuropathic pain and fibromyalgia in adults
aged 18 years and older. Duloxetine is not approved for use in
pediatric patients. Important Safety Information Duloxetine is
approved to treat major depressive disorder and generalized anxiety
disorder, and to manage diabetic peripheral neuropathic pain and
fibromyalgia. Antidepressants can increase suicidal thoughts and
behaviors in children, adolescents, and young adults. Patients
should call their doctor right away if they experience new or
worsening depression symptoms, unusual changes in behavior, or
thoughts of suicide. Be especially observant within the first few
months of treatment or after a change in dose. Duloxetine is
approved only for adults 18 and over. Duloxetine is not for
everyone. Patients should not take duloxetine if they have recently
taken a type of antidepressant called a monoamine oxidase inhibitor
(MAOI), are taking Mellaril(R) (thioridazine), or have uncontrolled
glaucoma. Patients should speak with their doctor about any medical
conditions they may have including kidney problems, glaucoma, or
diabetes. Patients should talk to their doctor if they have
itching, right upper belly pain, dark urine, yellow skin or eyes,
or unexplained flu-like symptoms, which may be signs of liver
problems. Severe liver problems, sometimes fatal, have been
reported. They should also talk to their doctor about alcohol
consumption. Patients should tell their doctor about all their
medicines, including those for migraine, to avoid a potentially
life-threatening condition. Taking duloxetine with NSAID pain
relievers, aspirin, or blood thinners may increase bleeding risk.
Patients should consult with their doctor before stopping
duloxetine or changing the dose and if they are pregnant or
nursing. Patients taking duloxetine may experience dizziness or
fainting upon standing. The most common side effects of duloxetine
include nausea, dry mouth, sleepiness, and constipation. This is
not a complete list of side effects. For full Patient Information,
