AstraZeneca plc (AZ) is a Swedish-British[3][4][5] multinational pharmaceutical and biotechnology company with its headquarters at the Cambridge Biomedical Campus in Cambridge, UK.It has a portfolio of products for major diseases in areas including oncology, cardiovascular, gastrointestinal, infection, neuroscience, respiratory, and inflammation.
The company was founded in 1999 through the merger of the Swedish Astra AB and the British Zeneca Group[6][7] (itself formed by the demerger of the pharmaceutical operations of Imperial Chemical Industries in 1993).Zeneca shareholders received 53.5% of the shares, while Astra shareholders received the remaining 46.5%.[8] Its portfolio includes primary and speciality care, coverage for rare diseases, and a robust global presence across various regions.[9] Since the merger it has been among the world's largest pharmaceutical companies and has made numerous corporate acquisitions, including Cambridge Antibody Technology (in 2006), MedImmune (in 2007), Spirogen (in 2013) and Definiens (by MedImmune in 2014).It has its research and development concentrated in three strategic centres: Cambridge, UK; Gothenburg, Sweden;[10][11] and Gaithersburg, Maryland, US.
AstraZeneca traces its earliest corporate history to 1913, when Astra AB was formed by a large group of doctors and apothecaries in Södertälje. Throughout the twentieth century, it grew into the largest pharmaceutical company in Sweden. Its British counterpart, Zeneca PLC was formed in 1993 when ICI divested its pharmaceuticals businesses; Astra AB and Zeneca PLC merged six years later, with the chosen headquarters in the United Kingdom.[12]
AstraZeneca's primary listing is on the London Stock Exchange and is a constituent of the FTSE 100 Index; it also secondary listings on Nasdaq Stockholm and the New York Stock Exchange.AstraZeneca has one of the highest market capitalisations of pharmaceutical companies worldwide.[13]

The primary uses are treatment of gastroesophageal reflux disease, treatment and maintenance of erosive esophagitis, treatment of duodenal ulcers caused by Helicobacter pylori, prevention of gastric ulcers in those on chronic NSAID therapy, and treatment of gastrointestinal ulcers associated with Crohn's disease.
When it is manufactured the result is a mixture of two mirror-imaged molecules, R and S. Two years before the omeprazole patent expired, AstraZeneca patented S-omeprazole in pure form, pointing out that since some people metabolise R-omeprazole slowly, pure S-omeprazole treatment would give higher dose efficiency and less variation between individuals.[135] In March 2001, the company began to market Nexium, as it would a brand new drug.[136]
The (R)-enantiomer of omeprazole is metabolized exclusively by the enzyme CYP2C19, which is expressed in very low amounts by 3% of the population. Treated with a normal dose of the enantiomeric mixture, these persons will experience blood levels five-times higher than those with normal CYP2C19 production. In contrast, esomeprazole is metabolized by both CYP2C19 and CYP3A4, providing less-variable drug exposure.[137] While omeprazole is approved only at doses of up to 20 mg for the treatment of gastroesophageal reflux,[138] esomeprazole is approved for doses up to 40 mg.[139]
In 2007, Marcia Angell, former editor-in-chief of the New England Journal of Medicine and a lecturer in social medicine at the Harvard Medical School, said in Stern, a German-language weekly newsmagazine, that AstraZeneca's scientists had misrepresented their research on the drug's efficiency, saying: "Instead of using presumably comparable doses [of each drug], the company's scientists used Nexium in higher dosages. They compared 20 and 40 mg Nexium with 20 mg Prilosec. With the cards having been marked in that way, Nexium looked like an improvement – which however was only small and shown in only two of the three studies."[140]
Bildman fraud, sexual harassment and faithless servant clawback
On 4 February 1998, Astra USA sued Lars Bildman, its former president and chief executive officer, seeking US$15 million for defrauding the company.[141] The sum included US$2.3 million in company funds he allegedly used to fix up three of his homes, plus money the company paid as the result of the EEOC investigation.Astra's lawsuit alleged Bildman sexually harassed and intimidated employees, used company funds for yachts and sex workers, destroyed documents and records, and concocted: "tales of conspiracy involving ex-KGBagents and competitors. This was in a last-ditch effort to distract attention from the real wrongdoer, Bildman himself."Bildman had already pleaded guilty in US District Court for failing to report more than US$1 million in income on his tax returns.In addition, several female co-workers filed personal sexual-harassment lawsuits against Bildman.[142] In April 1998, Bildman was sentenced to 21 months in prison three months after he pled guilty to filing false Federal tax returns.[143][144]
In February 1998, AstraZenaca's U.S. affiliate Astra U.S.A. agreed to a $10 million settlement after an Equal Employment Opportunity Commission investigation which started in May 1996 found that sexual harassment against female employees.[145] 120 former female employees of Astra were interviewed during the inquiry, with about 80 of them being identified as able to file claims.[145] Astra U.S.A. also issued a statement of apology for the hostile work environment.[145]
In Astra USA v. Bildman, 914 N.E.2d 36 (Mass. 2009), applying New York's faithless servant doctrine, the court held that a company's employee who had engaged in financial misdeeds and sexual harassment must "forfeit all of his salary and bonuses for the period of disloyalty".[146] The court held that this was the case even if the employee "otherwise performed valuable services", and that the employee was not entitled to recover restitution for the value of those other services.[146][147] The decision attracted a good deal of attention by legal commentators.[148]
CAFÉ study
In 2004, University of Minnesota research participant Dan Markingson took his own life while enrolled in an industry-sponsored pharmaceutical trial comparing three FDA-approved atypical antipsychotics: Seroquel (quetiapine), Zyprexa (olanzapine), and Risperdal (risperidone).University of Minnesota Professor of Bioethics Carl Elliott noted that Markingson was enrolled in the study against the wishes of his mother, Mary Weiss, and that he was forced to choose between enrolling in the study or being involuntarily committed to a state mental institution.[149] A 2005 FDA investigation cleared the university. Nonetheless, controversy around the case has continued. A Mother Jones article[149] resulted in a group of university faculty members sending a public letter to the university Board of Regents urging an external investigation into Markingson's death.[150]
Transfer mispricing
In February 2010, AstraZeneca agreed to pay £505 million to settle a UK tax dispute related to transfer mispricing.[151][152]
Conflicting commitments to the UK and the EU over COVID-19 vaccines
In August 2020, AstraZeneca made an advance purchase agreement with the European Commission and the EU member states for the supply of COVID-19 vaccines:
However, the UK Secretary of State for Health and Social Care, Matt Hancock, declared in March 2021 that the United Kingdom had been given "exclusivity" and that the EU's treaty was "inferior".[154][155] After placing the order for AstraZeneca's vaccine, the European Commission mistakenly assumed that it had enough vaccines and initially ordered only 200 million doses from Pfizer–BioNTech when the manufacturers offered 500 million doses to the EU in November 2020.[156]
However, the contract that AstraZeneca reached with the UK was very similar to that it reached with the EU, and it also contained the phrase "best reasonable efforts"; the UK contract was signed on 28 August 2020, a day after the contract with the EU.[157] The key difference seems to be that AstraZeneca entered into a preliminary agreement with the U.K. back in May 2020 which arranged for "the development of a dedicated supply chain for the U.K."[158] The failure to produce the vaccine in the anticipated quantities contributed to the low vaccination rates of vulnerable populations of the European Union at the beginning of the outbreak of more virulent variants of SARS-CoV-2 in early 2021.[159]
"13.1. AstraZeneca represents, warrants and covenants to the Commission and the Participating Member States that: [...] (e) it is not under any obligation, contractual or otherwise, to any Person or third party in respect of the Initial Europe Doses or that conflicts with or is inconsistent in any material respect with the terms of this Agreement or would impede the complete fulfilment of its obligation under this Agreement;"[153]
Operations in China and investigation
AstraZeneca's reputation in China was tarnished when its Chinese subsidiary did not quickly donate to relief efforts after the 2008 Sichuan earthquake.[160] Typically, donations for disaster relief in China are made through funds established through the Chinese Ministry of Civil Affairs and its subordinate organization, the Red Cross Society of China.[160] AstraZeneca had a corporate rule prohibiting foreign subsidiaries from making donations to local governments, and the company construed this rule as prohibiting donations for Sichuan earthquake relief efforts.[160] AstraZeneca's Chinese subsidiary suffered a major backlash for its failure to donate.[160] Corporate approval was eventually given for the Chinese subsidiary to donate, but only after a long delay.[160]
During the early 2020s, AstraZeneca expanded its R&D pipeline within China, increasing its investment in the country; the firm also signed licensing agreements with nine separate biotech firms in China that have been collectively valued at $6.5 billion.[161][162]
In May 2023, AstraZeneca's China president, Leon Wang, stated that the company aims to be a "patriotic" company in China that "loves the Communist Party."[163] On 30 October 2024, AstraZeneca revealed that Wang was under investigation by Chinese authorities and had been detained.[164] The China business is now being run by Michael Lai, the general manager.[164]
In November 2024, it was announced that Chinese officials had widened their investigation under a national anti-corruption campaign targeting healthcare. Among the allegations, former AstraZeneca employees are accused of falsifying genetic tests to secure reimbursement for the company’s lung cancer drug, Tagrisso.[165] Several current and former company executives are also being investigated for potentially breaching data privacy laws and for the suspected illegal importation of certain cancer drugs – likely including Enhertu, Imfinzi and Imjudo – from Hong Kong.[165]
Operations in Russia
Following Russia's invasion of Ukraine in 2022, AstraZeneca faced criticism for maintaining its operations and continuing certain clinical trials in Russia, despite promising to halt new investments in the country.[166] While several international pharmaceutical companies announced suspensions of new clinical studies in Russia after the conflict began, AstraZeneca moved forward with a study for a new COVID-19 prevention drug, essential for its registration in Russia.[167]

It also began a Phase I/II trial collaboration with Pharmacyclics and Janssen Biotech investigating combination treatments.[43] Also in November, AstraZeneca agreed to sell its lipodystrophy treatment business to Aegerion Pharmaceuticals for more than US$325 million.[44] In December, the company received acceleratedFDA approval for Olaparib in the treatment of women with advanced ovarian cancer who have a BRCA genetic mutation.
A major criterion governing the drugs approval was, on average, its ability to shrink tumours in patients for 7.9 months.[45]
The second of two deals is an agreement to study a combination treatment of MEDI4736 and Innate Pharma's Phase II anti-NKG2A antibody IPH2201 for up to US$1.275 billion.
The company's MedImmune arm also launched collaborative clinical trials with Juno Therapeutics, investigating combination treatments for cancer;[51] these trials involved combinations of MEDI4736 and one of Juno Therapeutics' CD19 directed chimeric antigen receptor T-cell candidates.[52] In June, the company revealed a partnership with Eolas Therapeutics on the Eolas Orexin-1 Receptor Antagonist (EORA) program for smoking cessation and other treatments.[53] In July, AstraZeneca announced the sale of its rights to Entocort (budesonide) to Tillotts Pharma for $215 million.[54] In July, Genzyme announced it would acquire the rare cancer drug Caprelsa (vandetanib) from AstraZeneca for up to US$300 million.[55]
In August, the company announced it had acquired the global rights to develop and commercialise Heptares Therapeutics' drug candidate HTL-1071, which focuses on blocking the adenosine A2A receptor, in a deal worth up to US$510 million.[56] That same month, the company's MedImmune subsidiary acquired exclusive rights to Inovio Pharmaceuticals' INO-3112 immunotherapy under an agreement which could net more than US$727.5 million for Inovio.INO-3112 targets Human papillomavirus types 16 and 18.[57] In September, Valeant licensed Brodalumab from the company for up to US$445 million.[58][59] On 6 November, it was reported that AstraZeneca had acquired ZS Pharma for US$2.7 billion.[60] In December, the company announced its intention to acquire the respiratory portfolio of Takeda Pharmaceutical – namely Alvesco and Omnaris – for US$575 million[61] A day later, the company announced it had taken a 55% majority stake in Acerta for US$4 billion; the transaction included commercial rights to Acerta's irreversible oral Bruton's tyrosine kinase inhibitor, acalabrutinib (ACP-196), which under development at that time.[62] In 2015, AstraZenica was the eighth-largest drug company in the world based on sales revenue.[63]
In September 2020, AstraZeneca acquired the preclinical oral
In December 2024, the company announced the appointment of Rene Haas and Birgit Conix to its board as non-executive directors.[103] Both appointments will be effective from January 2025 and February 2025 respectively.[103]
A day later, the company announced it had taken a 55% majority stake in Acerta for US$4 billion; the transaction included commercial rights to Acerta's irreversible oral
