Summary Judgment Granted for SEROQUEL® Patent Litigation

WILMINGTON, Del., July 1 /PRNewswire-FirstCall/ -- AstraZeneca today announced that the US District Court for the District of New Jersey has granted the company's Motion for Summary Judgment of No Inequitable Conduct. AstraZeneca had sued Teva Pharmaceutical Industries Ltd. and Sandoz, Inc. alleging infringement of AstraZeneca's patent as a result of Teva's and Sandoz's filings of Abbreviated New Drug Applications (ANDAs). The ANDAs sought approval to market generic versions of SEROQUEL(R) (quetiapine fumarate) tablets in the US before SEROQUEL's patent expires in 2011. Since the Court granted AstraZeneca's motion for Summary Judgment of No Inequitable Conduct in its entirety, trial is unnecessary.

"We are pleased with the Court's decision to uphold our valid intellectual property. SEROQUEL remains an important part of our company's portfolio benefiting patients and physicians throughout the world," said David Brennan, CEO of AstraZeneca.

AstraZeneca's Motion for Summary Judgment of No Inequitable Conduct sought judgment on all of the remaining liability issues in the case. Teva and Sandoz had already conceded infringement and the validity of AstraZeneca's patent. Thus, only the inequitable conduct contentions remained to be resolved. The Court had previously set a date for trial beginning on August 11, 2008.

Important Safety Information for SEROQUEL

SEROQUEL is indicated for the treatment of depressive episodes in bipolar disorder; acute manic episodes in bipolar I disorder, as either monotherapy or adjunct therapy to lithium or divalproex; for the maintenance treatment of bipolar I disorder as adjunct therapy to lithium or divalproex; and schizophrenia. Patients should be periodically reassessed to determine the need for continued treatment and the appropriate dose.

Elderly patients with dementia-related psychosis treated with atypical antipsychotic drugs are at an increased risk (1.6 to 1.7 times) of death, compared to placebo (4.5% vs 2.6%, respectively). SEROQUEL is not approved for the treatment of patients with dementia-related psychosis. (See Boxed Warning.)

Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies of major depressive disorder and other psychiatric disorders. Patients of all ages started on therapy should be observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. SEROQUEL is not approved for use in patients under the age of 18 years. (See Boxed Warning.)

Hyperglycemia, in some cases extreme and associated with ketoacidosis, hyperosmolar coma, or death, has been reported in patients treated with atypical antipsychotics, including SEROQUEL. The relationship of atypical use and glucose abnormalities is complicated by the possibility of increased risk of diabetes in the schizophrenic population and the increasing incidence of diabetes in the general population. However, epidemiological studies suggest an increased risk of treatment-emergent, hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics. Patients starting treatment with atypical antipsychotics who have or are at risk for diabetes should undergo fasting blood glucose testing at the beginning of and periodically during treatment. Patients who develop symptoms of hyperglycemia should also undergo fasting blood glucose testing.

A potentially fatal symptom complex, sometimes referred to as Neuroleptic Malignant Syndrome (NMS), has been reported in association with administration of antipsychotic drugs, including SEROQUEL. Rare cases of NMS have been reported with SEROQUEL. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. The management of NMS should include immediate discontinuation of antipsychotic drugs.

Leukopenia, neutropenia, and agranulocytosis (including fatal cases), have been reported temporally related to atypical antipsychotics, including SEROQUEL. Patients with a pre-existing low white blood cell (WBC) count or a history of drug induced leukopenia/neutropenia should have their complete blood count monitored frequently during the first few months of therapy. In these patients, SEROQUEL should be discontinued at the first sign of a decline in WBC absent other causative factors. Patients with neutropenia should be carefully monitored, and SEROQUEL should be discontinued in any patient if the absolute neutrophil count is < 1000/mm3.

Tardive dyskinesia (TD), a potentially irreversible syndrome of involuntary dyskinetic movements, may develop in patients treated with antipsychotic drugs. The risk of developing TD and the likelihood that it will become irreversible are believed to increase as the duration of treatment and total cumulative dose of antipsychotic drugs administered to the patient increase. TD may remit, partially or completely, if antipsychotic treatment is withdrawn. SEROQUEL should be prescribed in a manner that is most likely to minimize the occurrence of TD.
