ASTRAZENECA BIOLOGICS DIVISION, MEDIMMUNE, SUBMITS
BIOLOGICS LICENSE APPLICATION TO FDA FOR MOTAVIZUMAB

AstraZeneca PLC announced today that its biologics division, MedImmune, had submitted a Biologics License Application (BLA) to the U.S. Food & Drug Administration (FDA) for motavizumab, an investigational monoclonal antibody (MAb) derived from recombinant DNA technology.

“We expect that this submission will lead to the first new medicine delivered by MedImmune since we acquired the company in June 2007 and one of three new filings that we plan to make this year. MedImmune has a well-established reputation in the prevention of RSV through its existing product, Synagis. Motavizumab offers the opportunity to build on this knowledge and improve treatment for a young and vulnerable patient population,” said David Brennan, Chief Executive Officer, AstraZeneca.

Item 3
 
ASTRAZENECA TO APPEAL JUDGMENT IN ALABAMA
MEDICAL PRICING CASE

AstraZeneca today announced it intends to seek reconsideration or reversal of a verdict in the Montgomery County Circuit Court awarding $40 million in compensatory damages and $175 million in punitive damages for alleged false and misleading reporting of prices for drugs reimbursed by the Alabama State Medicaid Agency in the US.

The company was among 73 pharmaceutical manufacturers named in a lawsuit filed in 2005 by the Alabama Attorney General, alleging that misleading and false reported prices had caused Alabama Medicaid to reimburse pharmacists too much money on prescriptions filed for Medicaid patients.

AstraZeneca maintains that this lawsuit is legally and factually unfounded. The case was based on the misleading premise that the Alabama State Medicaid Agency did not understand how drug prices are established and reported. AstraZeneca also believes serious errors occurred during the proceedings and that the verdict should not be upheld.

AstraZeneca believes it has fully complied with the law, government guidelines and contracts that govern Medicaid pricing. AstraZeneca currently provides medicines to Medicaid programmes at the lowest price offered to its best business clients, as federal law requires.

AstraZeneca and the State Medicaid programme share a common goal of helping people access the medicines they need. To help patients who have difficulty affording their medicines, AstraZeneca offers patient assistance programmes side by side with its medicines. In the last two years alone, Alabama patients have received more than $25.5 million in savings through the company’s prescription savings programmes.

AstraZeneca Provides Update On RECENTINTM Clinical Development
Programme
 
HORIZON Colorectal Cancer Programme Continues Into Phase III; BR24 Non-Small
Cell Lung Cancer Trial Will Not Progress

AstraZeneca today announced that its HORIZON III Phase II/III head-to-head study of RECENTINTM (cediranib, AZD2171) with chemotherapy versus bevacizumab (Avastin) with chemotherapy in patients with first line metastatic colorectal cancer (CRC) will be progressing directly into Phase III at 20mg.  Patients will also continue to be recruited at 20mg into the first line CRC HORIZON II study of RECENTIN with chemotherapy versus chemotherapy alone.

The HORIZON Independent Data Monitoring Committee (IDMC) conducted a planned end of Phase II (EOP II) review of efficacy and tolerability data from HORIZON I, HORIZON II and HORIZON III. Data from HORIZON I, in second line colorectal cancer, would not by itself have contributed to a positive EOP II decision. However, when combined with a review of data from HORIZON II and III by the IDMC, the IDMC confirmed the HORIZON programme in 1st line CRC could continue and HORIZON II and III had met pre-defined EOP II criteria.

AstraZeneca today also announced that the National Cancer Institute of Canada Clinical Trials Group (NCIC-CTG) has informed AstraZeneca that the BR24 Phase II/III study of RECENTIN at 30mg in first line non-small cell lung cancer (NSCLC) will not continue into Phase III following the planned end of Phase II efficacy and tolerability analysis by the study’s Data Safety Monitoring Committee.  Although evidence of clinical activity was seen, there appeared to be an imbalance in toxicity and therefore the study was considered not to have met the pre-defined criteria for automatic continuation into Phase III.

AstraZeneca is working in close collaboration with the NCIC-CTG to understand the BR24 data further.


 
In addition to colorectal and non-small cell lung cancer, the RECENTIN development programme includes trials in recurrent glioblastoma and a number of signal search studies in other tumours.

John Patterson, AstraZeneca’s Executive Director for Development, said: “Given there is such a high unmet patient need for more effective treatments in cancer, we are pleased that the HORIZON colorectal cancer programme has met its pre-defined criteria to continue recruitment into Phase III. Due to the Phase II/III trial design, HORIZON III is able to move directly into Phase III utilising all the Phase II data and this saves valuable time in assessing the potential benefit of RECENTIN in the first line metastatic colorectal cancer setting.

“AstraZeneca supports the NCIC-CTG’s BR24 recommendation and is working with them to understand the data more fully in NSCLC. As evidence of clinical activity was seen in BR24, AstraZenenca remains committed to investigating the potential of RECENTIN in lung cancer and reducing the incidence of serious adverse events.”

RECENTINTM is a trademark of the AstraZeneca group of companies.

Notes To Editors:

About the National Cancer Institute of Canada Clinical Trials Group
The National Cancer Institute of Canada Clinical Trials Group (NCIC-CTG), funded by the Canadian Cancer Society and based at Queen's University in Kingston, Ontario, Canada, develops, conducts and analyses national and international trials of cancer therapy, including trials for new cancer drugs, cancer prevention and supportive care to improve quality of life for people with cancer. Since its inception in 1971, the NCIC-CTG has enrolled more than 40,000 patients from Canada and around the world in over 300 clinical trials.

BR24 Background
NSCLC accounts for approximately 80 percent of all cases of lung cancer. Lung cancer is the most common cancer in the world with 1.3 million new cases diagnosed every year and nearly 1.2 million people dying as a result of the disease annually.
 


BR24 is a collaboration between AstraZeneca and the NCIC-CTG, based at Queen’s University in Kingston, Ontario. The study is a randomised, double-blind, placebo-controlled Phase II/III investigation of RECENTIN plus paclitaxel and carboplatin versus the chemotherapy arm alone. In the Phase II part of the study, patients were recruited from countries including: Argentina, Australia, Brazil, Canada, Romania and Singapore.

RECENTIN and Colorectal Cancer
Colorectal cancer is the third most commonly reported cancer worldwide, with around 945,000 new cases and 492,000 deaths annually.

The Horizon Study Programme is evaluating RECENTIN in patients with first line advanced colorectal cancer:

RECENTIN: a potent and selective VEGF signalling inhibitor

RECENTIN is a once-daily, orally available, highly potent and selective VEGF signalling inhibitor that inhibits all three VEGF receptors.
 


VEGF signalling is a key driver of angiogenesis – the formation of new blood vessels that tumours need to grow and spread.  RECENTIN inhibits this signal by binding to the intracellular domain of all three VEGF receptors, in particular VEGFR-2, the predominant receptor through which VEGF exerts its effects on angiogenesis, preventing the growth of new blood vessels. This effectively “starves” the tumour of the oxygen and nutrients it needs to grow.

Phase I data indicate that RECENTIN is generally well tolerated, with the most common adverse events being diarrhoea, fatigue, hoarseness, nausea, vomiting, headache, hypertension and hand foot syndrome.

Item 8


ASTRAZENECA PROVIDES AN UPDATE ON THE STATUS OF ITS
ARRANGEMENTS WITH MERCK & CO., INC.

AstraZeneca today announced that, under the provisions of the agreements relating to the restructuring of the AstraZeneca and Merck & Co. joint venture in the United States, AstraZeneca has been informed that Merck has elected not to exercise the First Option related to the relinquishment of Merck’s rights over the products not covered by the Partial Retirement (see paragraph below), other than Nexium™ and Prilosec™.  As a result of this decision, contingent payments will continue on the products Atacand™, Lexxel™, Plendil™ and Entocort™ until at least 2010, at which time AstraZeneca may exercise this option at the 2008 Appraised Value of approximately $650 million.  The Appraised Value also includes rights to certain products that are still in clinical development (AZD6140, AZD3355, AZD0328 and AZD2327).  AstraZeneca made contingent payments in respect of the products included in the First Option of $69 million in 2007.

Other aspects of the scheduled termination arrangements will proceed as previously disclosed:

 
·
The Partial Retirement of Merck’s limited partnership interest, under which Merck’s rights in respect of certain products will end.  The products covered by the Partial Retirement include Toprol-XL™, Pulmicort™, Rhinocort™ and Symbicort™.  AstraZeneca made contingent payments in respect of these products amounting to $182 million in 2007.  AstraZeneca will pay Merck approximately $4.27 billion in respect of the Partial Retirement.
     
 
·
A true-up of the Advance Payment, which was triggered at the time of the merger between Astra and Zeneca, under which Merck relinquished all rights, including contingent payment on future sales, to potential Astra products with no existing or pending US patents at the time of the merger, amounting to a payment by Merck to AstraZeneca of approximately $0.24 billion, inclusive of interest.
     
 
·
Settlement of the loan note receivable by AstraZeneca from Merck, in the amount of $1.4 billion inclusive of accrued interest.


 
The combined effects of these three items will be a net cash outflow from AstraZeneca to Merck of approximately $2.63 billion upon settlement during the first quarter 2008.

Under the provision of the agreements a Second Option exists whereby AstraZeneca has the option to repurchase Merck’s interests in Prilosec™ and Nexium™ in the US.  This option is exercisable by AstraZeneca in 2012 should AstraZeneca exercise the First Option in 2010.  Exercise of the second option by AstraZeneca at a later date is also provided for in 2017 or if combined sales of the two products fall below a minimum amount provided, in each case, that the First Option has been exercised.  The exercise price for the Second Option is the net present value of the future annual contingent payments on Prilosec™ and Nexium™ as determined by the average valuation of two appraisers (one selected by each party) at the time of exercise, which is subject to a potential true-up mechanism under certain conditions.  AstraZeneca made contingent payments in respect of US sales for Prilosec™ and Nexium™ amounting to $931 million in 2007.

Further details on the accounting treatment of these events from an AstraZeneca perspective will be provided in conjunction with the Q1 2008 earnings announcement on 24 April, 2008.

AstraZeneca Submits sNDA for SeroquelXR for the Treatment of Major Depressive Disorder

AstraZeneca today announced submission of a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for once-daily SEROQUEL XR (quetiapine fumarate) Extended-Release Tablets to seek approval for the treatment of major depressive disorder (MDD) as monotherapy, adjunct therapy, and maintenance therapy in adult patients.

MDD affects 15 million American adults - between 5 and 8 percent of the population each year - and today it is often treated with generic or branded antidepressants. Studies have shown that at least one-third of patients with MDD treated with antidepressants fail to achieve a satisfactory response.  The American Psychiatric Association Practice Guidelines recommend switching to another class when two medications from the same class have proven ineffective.  AstraZeneca has investigated the use of SEROQUEL XR, an atypical antipsychotic, in the treatment of MDD, aiming to develop another potential treatment option, including treatment for patients who have failed or had an inadequate response to another antidepressant therapy.

The MDD submission is based on seven Phase III, placebo-controlled studies that assessed the efficacy and safety of once-daily treatment with SEROQUEL XR in patients diagnosed with MDD. Studies 1, 2, 3, and 4 were acute monotherapy studies involving 2,116 patients; Studies 6 and 7 were acute adjunct therapy studies (with ongoing antidepressant therapy) involving 939 patients who had an inadequate response to an antidepressant therapy; and Study 5 was a longer-term (up to 78 weeks) monotherapy maintenance study involving 1,854 patients.  The acute studies included in this submission used the Montgomery-Åsberg Depression Rating Scale (MADRS) as the primary assessment of depression symptoms. In the longer term study (Study 5), the primary assessment was time to a depressed event using criteria including MADRS. Doses of 50 mg, 150 mg and 300 mg of SEROQUEL XR were studied in the MDD programme. Across the whole programme, patients entering treatment in these seven clinical studies were drawn from 27 countries – three-
 

 
quarters of the patients were in North America – a further 10 percent were in Western Europe, 6 percent in Eastern Europe and the remainder were in Asia, South America, South Africa and Australia.

SEROQUEL XR™ is approved in the US and 18 further countries for the treatment of schizophrenia in adult patients and for maintenance treatment of schizophrenia in adult patients.  It was launched in the US in 2007 and last month AstraZeneca announced the submission of two separate sNDAs to the FDA for SEROQUEL XR seeking approval for the treatment of manic episodes associated with bipolar disorder and the treatment of depressive episodes associated with bipolar disorder – these remain under review by the FDA. In addition to the submission for MDD, the clinical development programme and planned regulatory filings for Seroquel XR extend to generalised anxiety disorder (GAD).

Launched in 1997, SEROQUEL® (quetiapine fumarate) is approved in 88 countries for the treatment of schizophrenia, in 79 countries for the treatment of bipolar mania, and in 11 countries including the USA for the treatment of bipolar depression. Global sales of Seroquel for 2007 passed the $4 billion mark for the first time, up 15 per cent on the previous year.

About Major Depressive Disorder
Major depressive disorder is a serious medical illness affecting 15 million American adults, or approximately 5 to 8 percent of the adult population in a given year. Depression occurs twice as frequently in women as in men. Unlike normal emotional experiences of sadness, loss, or passing mood states, major depressive disorder is persistent and can significantly interfere with an individual’s thoughts, behaviour, mood, activity, and physical health. Among all medical illnesses, major depressive disorder is the leading cause of disability in the U.S. and many other developed countries.

Symptoms of major depressive disorder characteristically represent a significant change from how a person functioned before the illness. The symptoms of depression include: persistently sad or irritable mood; pronounced changes in sleep, appetite, and energy; difficulty thinking, concentrating, and remembering; physical slowing or agitation; lack of interest in or pleasure from activities that were once enjoyed; feelings of guilt, worthlessness, hopelessness, and emptiness; recurrent
 

 
thoughts of death or suicide; and persistent physical symptoms for two or more weeks that do not respond to treatment, such as headaches, digestive disorders, and chronic pain.  Symptomatically, a major depressive episode in MDD is similar to a depressive episode of bipolar disorder with the major distinguishing feature between the disorders being the absence of manic or hypomanic symptoms in MDD. It has been reported that 69 per cent of patients with bipolar disorder were misdiagnosed, with the most frequent misdiagnosis being MDD.
