BeiGene is a global biotechnology company that specializes in the development of drugs for cancer treatment. Founded in 2010 by Xiaodong Wang and chief executive officer John V. Oyler, the company has offices in Asia, North America, Australia and Europe. BeiGene has developed several pharmaceuticals, including tislelizumab, a checkpoint inhibitor, and zanubrutinib, a Bruton's tyrosine kinase inhibitor.

History
BeiGene was founded in late 2010 by Xiaodong Wang, a Chinese-American scientist, and John V. Oyler, an American entrepreneur who serves as the company's chief executive officer and chairman. Wang and Oyler envisioned a biopharmaceutical company focusing on cancer treatment, with research and development both taking place in China.

The founders provided part of the initial seed money and also received early backing from the American pharmaceutical company Merck & Co. BeiGene established offices at the Zhongguancun Life Science Park near the, where Wang serves as director.

On February 2, 2016, BeiGene had its first initial public offering (IPO) of 6.6 million shares priced at $24 on the Nasdaq Stock Market under the ticker symbol BGNE. The company raised $182 million. The IPO, managed by Goldman Sachs and Morgan Stanley, was backed by Hillhouse BGN Holdings and Baker Brothers, which together planned to purchase half the shares offered. In a March 2018 follow-on offering, BeiGene raised another $758 million. In August 2018, the company had another IPO when it offered a secondary listing of its shares on the Hong Kong Stock Exchange, raising $903 million in the process.

, the company was constructing a $700 million investment site for biologics manufacturing and research and development. Located in Hopewell, New Jersey, it is scheduled to open in 2024.

Research and development
In addition to clinical research, BeiGene's early business model involved obtaining the rights to experimental medicines shelved by other pharmaceutical companies and taking them through early clinical trials at Chinese medical schools and hospitals. Successful formulas would either be sold to or co-developed with larger drugmakers who could fund the late-stage trials.

From 2019 to 2022, BeiGene's internal research team of preclinical scientists grew from 200 to more than 800 people. In 2022, BeiGene became the only pharmaceutical company in China to have invested more than 10 billion yuan ($145 billion) in research and development. , the company had approximately 50 clinical candidates or products in development or in the commercialization process.

Tislelizumab
One of BeiGene's internally developed medicines is tislelizumab (BGB-A317), a PD-1 antibody or PD-L1 inhibitor that prevents cancer tumors from evading the immune system. Tislelizumab is being developed as a monotherapy and for use in combination with other therapies for several types of cancer. In December 2019, it was approved by National Medical Products Administration in China for the treatment of Hodgkin lymphoma. In April 2020, tislelizumab was also approved in China to treat urothelial carcinoma. In September 2021, the U.S. Food and Drug Administration (FDA) accepted a biologics license application for tislelizumab to treat unresectable, recurrent locally advanced or metastatic esophageal squamous cell carcinoma that has previously been treated with systemic therapy.

Zanubrutinib
BeiGene also developed zanubrutinib, a Bruton's tyrosine kinase inhibitor for the treatment of cancer, from a formula its scientists created in Beijing in 2012. In November 2019, zanubrutinib became the first cancer drug developed in China to gain FDA approval; it received accelerated approval for the treatment of mantle cell lymphoma (MCL), a rare and aggressive form of non-Hodgkin lymphoma. In June 2020, the drug was also approved in China for the treatment of MCL, chronic lymphocytic leukemia (CLL), and small lymphocytic lymphoma (SLL); it was then approved for the treatment of CLL and SLL by the European Commission in November 2022 and by the FDA in January 2023. BeiGene is also testing zanubrutinib as a treatment for COVID-19. In September 2021, the FDA approved zanubrutinib to treat adults with Waldenström's macroglobulinemia, a rare non-Hodgkin lymphoma, and separately granted an accelerated approval for use of the drug in the treatment of relapsed or refractory marginal zone B-cell lymphoma in patients who have been treated with an anti-CD20 regimen.

Amgen
In 2019, Amgen Inc. acquired 20.5% of BeiGene in a deal valued at $2.7 billion, and gained a seat on BeiGene's board of directors. In turn, BeiGene acquired the rights to commercialize three Amgen pharmaceuticals, Xgeva, Kyprolis, and Blincyto, as well as 20 others in development, investing $1.25 billion toward their research. Amgen invested another $421 million in BeiGene in July 2020.

Celgene
In July 2017, BeiGene entered into a partnership with Celgene to continue the development and commercialization of the cancer drug BGB-A317, also known as tislelizumab. BeiGene also acquired Celgene's operations in China as well as the rights to commercialize Abraxane, Revlimid and Vidaza, Celgene's approved drugs in China. As part of the deal, Celgene made a $150 million equity investment in BeiGene and acquired the rights for the sale of tislelizumab overseas for $263 million, with another $980 million plus royalties contingent on future sales. The deal stipulated that, if Celgene began work on a competitor drug, BeiGene could buy back the rights to tislelizumab. In January 2019, Celgene was acquired by Bristol-Myers Squibb, which is developing a similar cancer immunotherapy drug, Opdivo, allowing BeiGene to regain its overseas rights to tislelizumab. Celgene returned the rights to the drug in June 2019 along with a payment of $150 million to conclude the deal.

Novartis
In January 2021, BeiGene announced a collaboration and license agreement with Novartis to develop and commercialize tislelizumab in Canada, member countries of the European Union, Switzerland, Iceland, Japan, Liechtenstein, Mexico, Norway, Russia, United Kingdom, and the U.S. The two companies announced late-stage trial results in April 2023 indicating that tislelizumab in conjunction with chemotherapy helped prolong survival for patients with types of gastric cancer, both with or without PD-L1 expression in their tumors.

Asieris Pharmaceuticals
In May 2021, BeiGene and Asieris Pharmaceuticals worked together to assess the efficacy and quality of Asieris's MetAP2 inhibitor and BeiGene's PD-L1 inhibitor for bladder cancer patients.

Max Foundation
The non-profit BeiGene Foundation partnered with the health equity non-profit Max Foundation to make Brukinsa available for free to patients in 29 countries over the following three years.

DualityBio
In July 2023, BeiGene acquired an exclusive license from DualityBio for an investigational antibody-drug conjugate for the treatment of certain solid tumors. DualityBio will continue research for the drug and support future Investigational New Drug applications.
