News for 'DDSS' - (Labopharm Receives FDA Approval For OLEPTRO(TM))
LAVAL, QC and PRINCETON, NJ, Feb. 3, 2010 (Canada NewsWire via COMTEX) -- -
Second U.S. FDA Product Approval in Just Over a Year For Labopharm's
CONTRAMID(R) Controlled Release Technology -
Labopharm Inc. (TSX: DDS; NASDAQ: DDSS) today announced the U.S. Food and Drug
Administration (FDA) has approved OLEPTRO(TM) (trazodone hydrochloride) Extended
Release Tablets, a novel once-daily formulation of the antidepressant trazodone,
for the treatment of major depressive disorder (MDD) in adults. OLEPTRO(TM)
utilizes CONTRAMID(R), Labopharm's clinically validated technology that controls
the release of active substances within oral medications.
"OLEPTRO(TM) represents Labopharm's second CONTRAMID(R) technology-based product
to receive FDA approval in just over a year," said James R. Howard-Tripp,
President and Chief Executive Officer, Labopharm Inc. "We are excited about the
opportunity for OLEPTRO(TM) and are preparing the product for launch into the
$11 billion-plus U.S. antidepressant market. We are working towards finalizing a
commercialization path for OLEPTRO(TM) that will maximize the value of our
product in this market."
MDD is a common mental illness often characterized by a combination of social
and somatic symptoms. It affects more than 14 million adults in the U.S. and is
the leading cause of disability globally. OLEPTRO(TM) will offer physicians
another therapeutic alternative for their MDD patients.
"There's a large body of evidence demonstrating the efficacy of trazodone in the
treatment of MDD," said Dr. Stephen Stahl, Adjunct Professor of Psychiatry,
University of California, San Diego School of Medicine. "Labopharm has developed
a novel formulation of trazodone that effectively treats depression and provides
a tolerable adverse event profile."
Labopharm is actively exploring several alternatives for the U.S.
commercialization of OLEPTRO(TM). Such alternatives range from out-licensing the
product to a distribution partner while retaining the right to some degree of
co-promotion, through to a full co-promotion arrangement under which Labopharm
would share the sales function with a partner. The Company currently expects to
finalize the commercialization plan for OLEPTRO(TM) in the near term.
Labopharm expects OLEPTRO(TM) to be available for prescription in the U.S. later
this year, with specific timing for its launch to be determined within the
context of the final commercialization plan. The Company believes it is well
advanced in its preparations for the U.S. launch of OLEPTRO(TM). The Company has
completed market research with physicians and third-party payors, developed a
positioning and marketing campaign for OLEPTRO(TM), and finalized product
manufacturing and packaging arrangements.
About the OLEPTRO(TM) Pivotal Study
An eight-week randomized, double-blind, two-arm, multi-centre study in patients
with unipolar major depressive disorder demonstrated OLEPTRO(TM)'s efficacy as a
treatment for depression. The primary efficacy endpoint of the study was to
compare the change in the Hamilton Rating Scale for Depression (HAMD-17) total
score from baseline to the end of the study in the OLEPTRO(TM) group versus the
placebo group. The results of this study, which are published in the May 2009
issue of Psychiatry, include the following:
<<
- Statistical significance was achieved for the primary endpoint
(p value of 0.012).
- The overall discontinuation rate in the study was 25 percent with
21 percent in the placebo group and 30 percent in the OLEPTRO(TM)
group.
- In the OLEPTRO(TM) group, four percent of patients discontinued
treatment due to somnolence or sedation.
>>
"Our research in the clinical study leading up to FDA approval showed that
OLEPTRO(TM) was well-tolerated and demonstrated a significantly greater
improvement in the HAMD-17 primary efficacy end point over placebo," said Dr.
David Sheehan, University Health Professor and Director of the Depression and
Anxiety Disorders Research Institute, University of South Florida College of
Medicine. "When given at the recommended daily dose range, OLEPTRO(TM) was an
appropriate monotherapy for patients with MDD."
Labopharm will conduct a post-approval pediatric study. The FDA has asked
Labopharm to provide data from a long-term maintenance study and an additional
in-vitro alcohol dissolution study.
About Major Depressive Disorder
Approximately two times more prevalent in women than men, MDD often co-exists
with other illnesses. Research shows that only approximately 65 percent of
individuals with MDD are diagnosed and, of those patients, 90 percent are
treated with medication.
Treating MDD with antidepressant medications is challenging for physicians
because patient response to antidepressant drug therapy varies significantly.
Research has shown that as many as 28 percent of patients being treated with
antidepressants stop taking their medication within the first four weeks of
treatment and as many as 44 percent stop within the first 12 weeks. Reasons for
discontinuing antidepressant treatment can include suboptimal efficacy, the
exacerbation of symptoms such as sleep disturbance, agitation, and sexual
dysfunction, and adverse events such as weight gain.
The FDA's decision represents the first regulatory approval for Labopharm's
novel, once-daily formulation of trazodone. The formulation is currently under
regulatory review in Canada.

Black Box Warning
Warning: Suicidality and Antidepressant Drugs
See full prescribing information for complete boxed warning
Increased risk of suicidal thinking and behavior in children, adolescents
and young adults taking antidepressants for major depressive disorder
(MDD) and other psychiatric disorders. OLEPTRO(TM) is not approved for
use in pediatric patients.
Warning and Precautions
- Patients with major depressive disorder (MDD), both adult and
pediatric, may experience worsening of their depression and/or the
emergence of suicidal ideation and behaviour, or unusual change in
behaviour, whether or not they are taking antidepressant medications.
Patients should be monitored for clinical worsening and suicidality
and for the appearance of any of the following symptoms: anxiety,
agitation, panic attacks, insomnia, irritability, hostility,
aggressiveness, impulsivity, akathisia, hypomania, and mania.
Families and caregivers should be alerted about the need to monitor
patients.
- The development of a potentially life-threatening serotonin syndrome,
or neuroleptic malignant syndrome (NMS)-like reactions has been
reported with antidepressants, and may occur with OLEPTRO(TM),
particularly with concomitant use of other serotoninergic drugs.
Treatment with OLEPTRO(TM) and any concomitant serotonergic or
antidopaminergic agents, including antipsychotics, should be
discontinued immediately and supportive treatment should be
initiated.
- A major depressive episode may be the initial presentation of bipolar
disorder. Prior to initiating treatment, patients should be
adequately screened to determine if they are at risk for bipolar
disorder and monitored for mania/hypomania. OLEPTRO(TM) is not
approved for use in treating bipolar depression.
- Experience with administration of immediate-release trazodone
products indicates that there may be an increased risk for QT
interval prolongation. QT prolongation may lead to Torsades de
pointes and even death especially in susceptible individuals, such as
those with hypokalemia, hypomagnesemia, or a genetic predisposition
to prolonged QT/QTc.
- Patients with pre-existing cardiac disease may be at more risk for
arrythmias. Concomitant administration of drugs that prolong the QT
interval or that are inhibitors of CYP3A4 may increase the risk of
cardiac arrhythmia in these patients.
- Orthostatic hypotension and syncope have been reported in patients
receiving trazodone hydrochloride.
- Drugs that interfere with serotonin reuptake, including trazodone
hydrochloride may increase the risk of bleeding events. Concomitant
use with NSAIDs, aspirin, or other drugs that affect coagulation may
compound this risk.
- Serious, sometimes fatal, reactions have been reported when
serotonergic drugs are used in combination with monoamine oxidase
inhibitor(s). Therefore, OLEPTRO(TM) should not be used concomitantly
or within 14 days of monoamine oxidase inhibitors.
- Rarely, cases of priapism can occur in men receiving trazodone.
OLEPTRO(TM) should be used with caution in men who have predisposing
conditions.
- There is a risk of hyponatremia when taking antidepressants. Elderly
patients may be at greater risk, as well as patients taking diuretics
or who are volume-depleted.
- OLEPTRO(TM) has the potential to impair judgment, thinking, and motor
skills. Advise patients to use caution before driving and when
operating machinery.
- Discontinuation symptoms may occur with abrupt discontinuation, and
may include anxiety, agitation and sleep disturbance. Upon
discontinuation, taper OLEPTRO(TM) and monitor for symptoms.

Adverse Reactions
The most common adverse reactions (incidence greater than or equal to five
percent and twice that of placebo) are: somnolence/sedation, dizziness,
constipation, blurred vision.
These are not all the possible adverse events of OLEPTRO(TM).
