European Commission approvals FLUENZ for prevention of seasonal influenza in children

On February 1, 2011 the Company announced that the European Commission (EC) has granted marketing authorization to FLUENZ Influenza Vaccine (Live Attenuated, Nasal), a nasally administered live attenuated influenza vaccine, for prevention of seasonal influenza for children 24 months to less than 18 years of age. This decision follows the positive opinion from the Committee for Medicinal Products for Human Use (CHMP) on October 22, 2010 and is applicable to the 27 Member States and the 3 European Economic Area countries of the European Union.

It is expected that the FLUENZ vaccine will be initially available in select European markets for the 2012-13 influenza season. The EC decision and CHMP positive opinion were reached after a review of data from 73 global clinical studies and US post-marketing studies of more than 141,000 subjects conducted in 38 countries. Study objectives included clinical safety and tolerability, clinical efficacy and effectiveness, and immunogenicity.

US FDA assigns new PDUFA date for BRILINTA

On February 4, 2011 the Company announced that the US Food and Drug Administration (FDA) has acknowledged receipt of the Company’s reply to the Complete Response Letter (CRL) for the ticagrelor New Drug Application (NDA). Accordingly, the agency has accepted AstraZeneca’s resubmission of the ticagrelor NDA, categorized it as a Class 2 resubmission to the CRL, and set a new Prescription Drug User Fee Act (PDUFA) date of July 20, 2011.

The FDA issued the CRL on December 16, 2010. On January 21, 2011, AstraZeneca announced it had submitted the requested supplementary analyses as part of its CRL response. AstraZeneca remains confident in the NDA submission for ticagrelor and will continue working with the FDA to progress towards completing the review of the NDA for ticagrelor.

AstraZeneca halts Phase III trial of ZIBOTENTAN in non-metastatic castrate resistant prostate cancer

On February 7, 2011 the Company announced that the phase III ENTHUSE Study 15, studying zibotentan monotherapy in patients with non-metastatic castrate resistant prostate cancer (CRPC), will be stopped following the results of an early efficacy review by the Independent Data Monitoring Committee. The decision was made after this review indicated that zibotentan monotherapy was unlikely to meet its primary efficacy endpoints (progression free survival and overall survival) and therefore unlikely to benefit patients with non-metastatic CRPC.

AstraZeneca felt it was prudent to take an early view on the progress of Study 15 following the announcement in September 2010 that ENTHUSE Study 14, evaluating zibotentan monotherapy, did not show a significant improvement in the primary endpoint of overall survival in patients with metastatic CRPC.

Study 15 is part of the Phase III clinical trial program, ENTHUSE, which was developed to evaluate the efficacy and safety of zibotentan in extending survival in men with CRPC. The discontinuation of Study 15 concludes the zibotentan monotherapy program in CRPC. The full data from Study 15 will be published in due course. ENTHUSE Study 33 is a trial using zibotentan in combination with standard chemotherapy in a more advanced metastatic CRPC setting. This trial will continue and full results are expected in the second half of 2011.

AstraZeneca and Targacept initiate Phase IIB clinical trial of TC-5214 as “switch” monotherapy treatment for MDD

On February 7, 2011 the Company and Targacept, Inc. announced the enrolment of the first patient in the Phase IIb clinical trial of TC-5214, a nicotinic channel blocker, as a “switch” monotherapy treatment for patients with major depressive disorder (MDD) who do not respond adequately to initial antidepressant therapy. This study is in addition to the companies’ Phase III RENAISSANCE program for TC-5214 as an adjunctive treatment for MDD. The RENAISSANCE program is designed to support an NDA filing in the US planned for the second half of 2012 and a Marketing Authorization Application (MAA) filing in Europe planned for 2015. AstraZeneca and Targacept are co-developing TC-5214.

In the Phase IIb study, patients with MDD who do not respond adequately, based on predefined criteria, to initial open label treatment with one of six commonly used SSRI or SNRI antidepressants will be switched to receive either one of two fixed doses of TC-5214, the active control duloxetine or placebo. Dosing in this double blind phase of the study is twice daily for eight weeks. The primary outcome measure for the study is change from double-blind baseline at the end of the dosing period for TC-5214 on the Montgomery-Åsberg Depression Rating Scale as compared to placebo. The study is projected to enrol approximately 350 patients into the double blind phase from approximately 75 centers worldwide.

ONGLYZA US label update provides further evidence regarding use in renally impaired adults with Type 2 diabetes

On February 23, 2011 the Company and Bristol-Myers Squibb Company announced that the FDA has approved the inclusion of data from two clinical studies in an update to the ONGLYZA (saxagliptin) US Prescribing Information for adult type 2 diabetes patients.

The renal study investigated the safety and efficacy of ONGLYZA in patients with moderate to severe renal impairment or end-stage renal disease (ESRD). The 12-week data showed that ONGLYZA 2.5 mg once daily significantly improved glycosylated hemoglobin (HbA1c) from baseline compared to placebo when added to patients’ current diabetes treatment. In patients with ESRD, ONGLYZA and placebo showed numerically comparable reductions in HbA1c. This finding is inconclusive because the trial was not adequately powered to show efficacy within specific subgroups of renal impairment. The incidence of adverse events was similar between ONGLYZA and placebo.

The data from a separate 52-week study comparing ONGLYZA to titrated glipizide in patients with inadequate glyceamic control on metformin therapy plus diet and exercise showed that ONGLYZA plus metformin provided similar HbA1c reductions from baseline. This conclusion may be limited to patients with baseline HbA1c comparable to those in the trial. ONGLYZA plus metformin also resulted in significantly less confirmed hypoglycaemia, as well as weight loss compared to weight gain versus titrated glipizide plus metformin.

ONGLYZA is indicated as an adjunct to diet and exercise to improve blood sugar (glyceamic) control in adults with type 2 diabetes mellitus in multiple clinical settings. ONGLYZA should not be used for the treatment of type 1 diabetes or for the treatment of diabetic ketoacidosis (dangerously high levels of ketones in the blood or urine).

If used with an insulin secretagogue such as a sulfonylurea, a lower dose of the insulin secretagogue may be required to reduce the risk of hypoglycaemia. There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with ONGLYZA or any other antidiabetic drug.

ONGLYZA becomes first DPP4 inhibitor available for use in Europe in Type 2 Diabetes patients with moderate or severe renal impairment

On March 4, 2011 the Company and Bristol-Myers Squibb Company announced that the European Commission has approved a label update for ONGLYZA® (saxagliptin) in the treatment of adults with type 2 diabetes who have moderate or severe renal impairment. The approved dosage for the patient group is a new once-daily 2.5 mg dose.

ONGLYZA will be the first dipeptidyl peptidase-4 (DPP-4) inhibitor in Europe available for type 2 diabetes patients with moderate or severe renal impairment. ONGLYZA is indicated in adult patients with type 2 diabetes mellitus to improve glycaemic control in combination with metformin, sulphonylurea, or thiazolidinedione, when each treatment alone, with diet and exercise, does not provide adequate glycaemic control.

This label update was granted on the basis of clinical data submitted to the European Medicines Agency from a 12-week, multi-centre, randomized, double-blind, placebo-controlled study to evaluate the treatment effect of ONGLYZA 2.5 mg once daily compared with placebo in 170 patients with Type 2 diabetes and renal impairment (creatinine clearance [CrCl] <50 mL/min). In this study, 98.2% of the patients were treated with other antihyperglycaemic medication. The results of the study, which are described in the Summary of Product Characteristics (SmPc), demonstrated that ONGLYZA 2.5 mg was safe and effective, compared with placebo, in adults with type 2 diabetes who have moderate or severe renal impairment.

AstraZeneca to discontinue production of PULMICORT ® pMDI

On March 7, 2011 the Company announced that it will discontinue the production of PULMICORT® (budesonide) 100 and 200 µg/dose HFA pMDI (pressurized metered dose inhaler) due to complex manufacturing issues related to technical aspects of the device, which prevents the ongoing manufacture of the product. This issue is not related to the active ingredient, budesonide, or any other AstraZeneca product.

The manufacturing decision took effect immediately; however, patients can continue using the PULMICORT pMDI 100 and 200 µg strength until their current supply is finished.

PULMICORT pMDI is manufactured using product-specific processes and components, the combination of which is not used with any other AstraZeneca respiratory products; therefore, this is a unique issue to PULMICORT pMDI.

AstraZeneca is working closely with the appropriate regulatory authorities and healthcare professionals (HCPs), and is informing manufacturers of similar asthma medications, where appropriate, to ensure all patients continue to receive the appropriate alternative treatment.

Other AstraZeneca respiratory products, including PULMICORT® Turbuhaler®, PULMICORT® Respules® and PULMICORT® Flexhaler® are not affected because they use different devices or device components. Other AstraZeneca pMDI products such as SYMBICORT® budesonide/formoterol fumarate dihydrate) pMDI and VANNAIR© (budesonide/formoterol) are also not affected.

FDA accepts NDA for Dapagliflozin for treatment of Type 2 diabetes

On March 8, 2011 the Company and Bristol-Myers Squibb Company announced that the FDA has accepted for review an NDA for dapagliflozin, an investigational compound for the treatment of adults with type 2 diabetes mellitus. An MAA for dapagliflozin has also been validated by the European Medicines Agency (EMA). The NDA and MAA submissions for dapagliflozin were filed in December 2010. The PDUFA goal date for the FDA is October 28, 2011.

The US and European submissions included data of up to two years in duration from a global development program involving approximately 6,000 individuals in 40 clinical studies. In accordance with FDA guidelines, the US application also includes data assessing the cardiovascular safety of dapagliflozin in adults with type 2 diabetes.

AstraZeneca initiates phase III clinical program evaluating NKTR-118 for treatment of opioid-induced constipation

On March 15, 2011 the Company announced enrolment of the first patient in the Phase III clinical program for NKTR-118, an oral peripherally-acting opioid antagonist being investigated for the treatment of opioid-induced constipation. The Phase III clinical program is designed to investigate the safety and efficacy of NKTR-118 as a medicine to relieve opioid induced constipation, a common side effect of prescription opioids when used for chronic pain management. NKTR-118 is part of the exclusive worldwide license agreement announced on September 21, 2009 between AstraZeneca and Nektar Therapeutics.

The Phase III clinical program will consist of two 12-week, randomized, placebo-controlled efficacy studies (with approximately 630 randomized patients each) and an open-label, randomized, long-term safety study with a “usual care” comparator arm. The 12-week efficacy studies will compare response rate among placebo and two different doses of NKTR-118 with primary endpoint at 4 weeks. There is a three month safety extension following one of the two 12-week studies.

The long-term safety study will include patients from the 12-week treatment in the efficacy studies, as well as new patients not previously enrolled. All patients will be randomly assigned to open-label treatment of either NKTR-118 or physician’s choice (usual care) of laxative regimen. Safety assessments will also be collected throughout the trials.

The first regulatory filings based on the program are planned for 2013.

FDA approves orphan drug vandetanib

On April 7, 2011 the Company announced that the FDA has approved the orphan drug vandetanib for the treatment of medullary thyroid cancer that cannot be removed by surgery or that has spread to other parts of the body. Vandetanib is a kinase inhibitor indicated for the treatment of symptomatic or progressive medullary thyroid cancer in patients with unresectable (non-operable) locally advanced or metastatic disease.

As previously disclosed, in December 2010, AstraZeneca received a second Notice of Allegation from Teva Canada Limited (Teva) in respect of Canadian Atacand substance patent no. 2,040,955 (the ‘955 patent) and formulation patent no. 2,083,305 (the ‘305 patent) listed on the Canadian Patent Register for Atacand. Teva has confirmed it will await the expiry of the ‘955 patent. AstraZeneca did not commence an application in response.

In March 2011, AstraZeneca received a Notice of Allegation from Apotex Inc. (Apotex) in respect of the ‘955 and ‘305 patents listed on the Canadian Patent Register for Atacand. Apotex has confirmed it will await the expiry of the ‘955 patent. AstraZeneca did not commence an application in response.

Patent litigation – Brazil

As previously disclosed, in October 2010, AstraZeneca filed an infringement action with a request for an interlocutory injunction against Sandoz do Brasil Industria Farmaceutica Ltda (Sandoz) in the Central Court of São Paolo. The Court denied the request for an interlocutory injunction. AstraZeneca appealed the decision and in February 2011, the Court of Appeal upheld the lower court’s decision to deny the request for an interlocutory injunction. The main infringement action continues.

Patent litigation – EU

As previously disclosed, in Portugal, a request was filed with the Lisbon Administrative Court of First Instance in December 2009 seeking a preliminary injunction to suspend the marketing authorizations for generic candesartan cilexetil granted to Sandoz Farmacêutica Limitada (Sandoz). The Court denied the preliminary injunction. The decision was appealed and the Court of Appeal ordered the Court of First Instance to hold a hearing. After a hearing in February 2011 the Lisbon Administrative Court of First Instance granted the request for a preliminary injunction and ordered the suspension of the marketing authorizations granted to Sandoz until October 24, 2012, i.e. the date of expiry of the supplementary protection certificate. This decision can be appealed.

Atacand Plus (candesartan cilexetil/hydrochlorothiazide)

Patent litigation – Canada

As previously disclosed, in April 2010, AstraZeneca received a Notice of Allegation from Pharmascience Inc. (PMS) in respect of the Atacand Plus formulation patent no. 2,083,305 (the ‘305 patent) listed on the Canadian Patent

Register for Atacand Plus. AstraZeneca commenced a proceeding in response in June 2010. In February 2011, AstraZeneca discontinued its application.

As previously disclosed, in December 2010, AstraZeneca received a Notice of Allegation from PMS in respect of the Atacand Plus combination patent no. 2,125,251 (the ‘251 patent). AstraZeneca commenced an application in response in February 2011.

In January 2011, AstraZeneca received two Notices of Allegation from Teva Canada Limited (Teva) in respect of the ‘251 and the ‘305 patents. Teva has agreed to await the expiry of the ‘955 patent. AstraZeneca commenced applications in response in March 2011.

Crestor (rosuvastatin calcium)

Patent litigation – US

US Patent No. RE37,314 (the ‘314 patent)

As previously disclosed, in June 2010, the US District Court for the District of Delaware found the ‘314 patent valid and enforceable and infringed by the eight generic defendants. The defendants appealed the decision to the Court of Appeals for the Federal Circuit. AstraZeneca and Shionogi Seiyaku Kabushiki Kaisha filed a comprehensive responsive brief in March 2011. The defendants filed reply briefs and briefing is now complete. A date for oral argument has not been set.

505(b)(2) New Drug Application for rosuvastatin zinc tablets (the ‘314 patent) and US Patent Nos. 6,858,618 (the ‘618 patent) and 7,030,152 (the ‘152 patent)

As previously disclosed, in October 2010, AstraZeneca and Shionogi Seiyaku Kabushiki Kaisha commenced a patent infringement action in the US District Court for the District of Delaware against Watson Laboratories, Inc. (Watson) for infringement of the ‘314 patent. In March 2011, the Court entered an order based on a stipulation which precludes Watson from re-litigating the invalidity and unenforceability issues currently pending before the Federal Circuit in the Crestor appeal involving the ‘314 patent. The Court has set a case-schedule for discovery and other litigation events, including a trial date in May 2012. On April 19, 2011, in this case, AstraZeneca moved to amend the complaint to add The Brighams & Women’s Hospital as a co-plaintiff and add claims of infringement of the ‘618 and ‘152 method patents.

Abbreviated New Drug Applications for rosuvastatin calcium tablets (the ‘618 and ‘152 patents)

In 2010, AstraZeneca and The Brighams & Women’s Hospital, AstraZeneca’s licensor of the ‘152 patent (together the Plaintiffs), filed ten patent infringement actions involving Crestor in the US District Court for the District of Delaware, based on the ‘152 patent and the ‘618 patent. As previously disclosed in December 2010, the Court dismissed nine of the infringement actions for lack of subject-matter jurisdiction. In January 2011, the Plaintiffs appealed the dismissals to the Federal Circuit. The Plaintiffs also asked the District Court to stay the remaining action against Sandoz Inc. pending the outcome of the appeals. In March 2011, the Plaintiffs filed an opening brief in the Federal Circuit.

Management’s Annual Report on Internal Control over Financial Reporting

As required by US regulations, management is responsible for establishing and maintaining adequate internal control over financial reporting for the company, and is required to identify the framework used to evaluate the effectiveness of the Company’s internal control over financial reporting and to assess the effectiveness of such internal control. In this regard, management has made the same assessment and reached the same conclusion as that set forth in the section entitled “Financial Statements—Director’s Responsibilities for, and Report on, Internal Control over Financial Reporting” on page 136 of the Company’s “Annual Report and Form 20-F Information 2010” included as exhibit 15.1 to this Form 20-F dated April 28, 2011, which is incorporated herein by reference.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

AstraZeneca PLC:

We have audited AstraZeneca PLC’s (“AstraZeneca”) internal control over financial reporting as of 31 December 2010, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). AstraZeneca’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, AstraZeneca maintained, in all material respects, effective internal control over financial reporting as of 31 December 2010, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the PCAOB, the consolidated statements of financial position of AstraZeneca and subsidiaries as of 31 December 2010, 2009 and 2008, and the related consolidated statements of comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended 31 December 2010, and our report dated 27 January 2011 expressed an unqualified opinion on those consolidated financial statements.

ITEM 16G. CORPORATE GOVERNANCE

AstraZeneca PLC is a public limited company incorporated in England and Wales, listed on the London Stock Exchange and is subject to the authority of the Financial Services Authority in the UK. As a result, it follows the UK Corporate Governance Code (the “UK Code”), which came into effect for the Company as of January 1, 2011 (formerly, the UK Combined Code on Corporate Governance), in respect of its corporate governance practices. The Company has ADRs listed on the NYSE and, under the NYSE Corporate Governance Standards (the “NYSE Standards”) applicable to listed companies, as a foreign private issuer, the Company is permitted to follow the corporate governance practice of its home country in lieu of certain provisions of the NYSE Standards.

A summary of the significant ways in which the Company’s corporate governance practices differ from those followed by US domestic companies under the NYSE Standards is set forth below.

NYSE Standards		AstraZeneca Corporate Governance Practice

1. Under the NYSE Standards, the audit committee is to be directly responsible for the appointment, compensation, retention and oversight of a listed company’s external auditor, unless there is a conflicting requirement under the home country laws of the company.		Under the UK Code, a company’s external auditors are appointed by its shareholders. As a result, the Company’s audit committee is responsible for making recommendations to the Board of Directors, for the Board of Directors to propose to the Company’s shareholders in general meeting, in relation to the appointment, re-appointment and removal of the external auditors, and

NYSE Standards		AstraZeneca Corporate Governance Practice

		for approving the remuneration and terms of engagement of the external auditor.
2. NYSE Standards, the nominating/corporate governance committee and compensation committee are to be composed entirely of independent directors.		Under the UK Code, a majority of the members of a company’s nomination committee, and all of the members of its remuneration committee, should be independent non-executive directors. The Company’s Nomination and Governance Committee and Remuneration Committee each includes four members, including the chairman of the Company’s Board of Directors, with the remainder all being considered by the Company’s Board of Directors to be independent in accordance with the principles and criteria of the UK Code. The Company’s chairman was considered to be independent upon his appointment as chairman (under the UK Code, the test of independence is not appropriate in relation to the chairman thereafter).

3. Under the NYSE Standards, the compensation committee is to make recommendations to the listed company’s Board of Directors with respect to non-CEO executive officer compensation and certain other compensation plans which are subject to Board approval.		In compliance with the UK Code, the Company’s Remuneration Committee determines the Company’s global remuneration frameworks and principles, approves individual salary decisions and related matters for members of the Company’s Board of Directors, Senior Executive Team (“SET”) and the Company Secretary, and reviews annual bonus payments for all executives reporting directly to SET members. While the Remuneration Committee does not make initial recommendations to the Board of Directors in this respect, it does report to the Board of Directors on these matters.


4. Under the NYSE Standards, shareholders are entitled to vote on all equity compensation plans and material revisions thereto, with certain limited exemptions.		Under the listing rules of the UK Listing Authority (the “UKLA Rules”), with which the Company complies, shareholder approval is required to be obtained by the Company for the adoption of equity compensation plans which are either long-term incentive schemes in which directors of the Company can participate or schemes which may involve the issue of new shares. Under the UKLA Rules, these plans may not be changed to the benefit of the plan participants unless shareholder approval is obtained (with certain minor exceptions, for example, to benefit the administration of the plan or to take account of tax benefits). The UKLA Rules in respect of shareholder approval regarding equity compensation plans, or any material revision thereto, may differ from the NYSE Standards.

5. Under the NYSE Standards, each listed company Chief Executive Officer must certify to the NYSE each year that he or she is not aware of any violation by the listed company of any NYSE corporate governance listing standards.		As the Company is a foreign private issuer, the Company’s Chief Executive Officer is not required to make this certification. He is, however, required to promptly notify the NYSE in writing after any executive officer of the Company become aware of any non-compliance with any NYSE corporate governance rules applicable to the Company.
