Monday December 13, 2:00 am ETBASINGSTOKE, England and PHILADELPHIA, Pennsylvania, December 13
/PRNewswire-FirstCall/ -- Shire Pharmaceuticals Group plc (LSE: SHP, NASDAQ:
SHPGY, TSX: SHQ) announces that the US Food & Drug Administration (FDA) has
approved EQUETRO(TM) (extended-release carbamazepine capsules), previously
known as SPD417, for the treatment of patients with Bipolar Disorder, ten
months after submission.ADVERTISEMENT
Bipolar Disorder is one of the six leading mental disorders worldwide, according to the World Health Organization.[i] Each year, it is estimated that more than 2 million American adults[ii], [iii], about 1 percent of the population age 18 and older,[iv] are afflicted with Bipolar Disorder, also known as manic depression. Of the 750,000 currently diagnosed, about 650,000 are treated. The bipolar market in the United States is currently valued at about US$1.9bn and is expected to grow to $2.4bn by 2007(++).Bipolar Disorder is characterized by episodes of mania and depression, with periods of normal mood in between. The disorder can have devastating effects on an individual's life, although proper diagnosis and earlier treatment can usually alter the course of the illness.
EQUETRO significantly reduces the manic symptoms in Bipolar patients. Additionally, in clinical trials, patients treated with the product demonstrated no clinically significant weight gain or increase in blood glucose levels, thereby creating an effective tolerability profile(+). The unique three-bead extended release delivery system of Equetro provides for convenient administration as well. Available in 100, 200 and 300mg dosage strengths, it is the only carbamazepine formulation proven effective for patients with Bipolar Disorder.
EQUETRO has a formulation patent that runs until 2011 and will have three years market exclusivity under the US Hatch-Waxman Act. It will be available for prescribing in the US in the first quarter of 2005.
Matthew Emmens, Chief Executive of Shire commented:
"Bipolar Disorder is a debilitating condition that affects the patient and their family members. EQUETRO(TM) brings a new choice of treatment that can make a real difference to the lives of those who suffer from this distressing and serious illness.
"This is the sixth(+++) regulatory approval that Shire has received in 2004. It demonstrates the quality of our late stage pipeline and the competence of our R&D team. Approval of EQUETRO enables Shire to bring its established expertise in CNS to this large and increasingly recognized market."
Richard H. Weisler, M.D., primary investigator of two EQUETRO clinical trials comments:
"The approval of the extended-release carbamazepine capsule, EQUETRO(TM), with an improved tolerability profile allows for a more rapid dosage titration that should provide physicians with a powerful new treatment option. EQUETRO demonstrates significant reduction of manic symptoms in both manic and mixed patients as early as the first week of treatment. EQUETRO showed improvement in treating depressive symptoms in mixed patients who suffer both significant depression and mania at the same time. Having a new drug treatment option that is effective for bipolar disorder without causing significant weight gain or blood sugar changes is a very important addition to our armamentarium."
Dr. Weisler is an adjunct professor of psychiatry at University of North Carolina at Chapel Hill School of Medicine and an adjunct assistant professor of psychiatry and behavioral sciences at Duke University Medical Center.
Notes to Editors:
EQUETRO(TM) is indicated for the treatment of acute manic and mixed episodes associated with Bipolar I Disorder.
(+)An analysis of pooled data from two identically designed, three-week, double-blind, placebo-controlled phase III trials of EQUETRO monotherapy in patients initially requiring hospitalisation. The trial involved 443 patients aged 18 to 76 with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of bipolar disorder (current episode manic or mixed) who were randomised to double-blind treatment with either EQUETRO or placebo.The pooled analysis revealed that by the end of the trials, EQUETRO patients, both manic and mixed, experienced significant reductions in Young Mania Rating Scale total scores as well as significant improvements in Clinical Global Impression-Severity and Clinical Global Impression-Improvement scores. Also, EQUETRO-treated mixed patients experienced total score improvements on the Hamilton Depression Rating Scale. Investigators measured the safety and tolerability of EQUETRO by measuring participants' weight, blood glucose, cholesterol and interval between heartbeats, as well as adverse event monitoring. Dr. Weisler reported the pooled data analysis Nov. 18, 2004 at the 17th annual U.S. Psychiatric and Mental Health Congress in San Diego, California.
