Biogen Inc. is an American multinational biotechnology company based in Cambridge, Massachusetts, United States specializing in the discovery, development, and delivery of the treatment of neurological diseases to patients worldwide. Biogen operates in Argentina, Brazil, Canada, China, France, Germany, Hungary, India, Italy, Japan, Mexico, Netherlands, Poland, Sweden, and Switzerland.[2]

## History

[edit]

Biogen was founded in 1978 in Geneva as Biotechnology Geneva by several prominent biologists, including Kenneth Murray from the University of Edinburgh, Phillip Allen Sharp from the Massachusetts Institute of Technology, Walter Gilbert from Harvard University (Gilbert served as CEO during the start-up phase of Biogen), Heinz Schaller from the University of Heidelberg, and Charles Weissmann from the University of Zurich (Weissmann contributed the first product interferon alpha).[3][4] Gilbert and Sharp were subsequently honored with Nobel Prizes: Gilbert was recognized in 1980 with the Nobel Prize in Chemistry for his understanding of DNA sequencing[5] and Sharp received the Nobel Prize in Physiology or Medicine in 1993 for his discovery of split genes.[6]

In 2003, Biogen merged with San Diego, California-based IDEC Pharmaceuticals (formed in 1985 by University of California-San Diego's physicians and immunologists Ivor Royston and Robert E. Sobol, San Diego bio entrepreneur Howard Birndorf, and Stanford University cancer researchers Ron Levy and Richard Miller) and adopted the name Biogen Idec.[7][8] After the merger, Biogen Idec became the 3rd largest Biotechnology company in the world.[9]

Following shifts in research core areas, the company has since shortened its name, reverting to simply Biogen.[10] Biogen stock is a component of several stock indices such as the S&P 500, S&P 1500, and NASDAQ-100 and the company is listed on the NASDAQ stock exchange under the ticker symbol, BIIB.[11]

In May 2006, the company announced it would acquire cancer specialist, Conforma Therapeutics for $250 million.[12] Later in the same month, the company announced its intention to acquire Fumapharm AG, consolidating ownership of Fumaderm and BG-12, an oral fumarate, which was being studied for the treatment of multiple sclerosis and psoriasis.[13]

In January 2007, the company announced it would acquire Syntonix Pharmaceuticals for up to $120 million, gaining Syntonix's lead product for hemophilia B as well as the technology for developing inhalable treatments.[14][15]

In 2008, two new brain infection cases from Tysabri users surfaced in Europe that raised international concern about Tysabri and its effects with the progressive multifocal leukoencephalopathy (PML) brain condition. Biogen is one of the drug's producers.[16]

In 2011, Biogen announced that its drug Fampyra received conditional marketing approval. Under the conditional approval, Biogen agrees to provide additional data on the long-term benefits and safety of Fampyra.[17]

On December 10, 2012, Biogen announced its global collaboration agreement with Isis Pharmaceuticals to develop and research antisense drugs to treat neurological and neuromuscular diseases.[18]

In February 2013, Bloomberg broke the news that Biogen was planning to pay Elan $3.25 billion for the full rights to Tysabri, used to treat multiple sclerosis.[19]

In 2013, Biogen was the first U.S.-based biotechnology company to appear on the Dow Jones Sustainability World Index.[20]

In January 2015, the company announced that it would acquire Convergence Pharmaceuticals for up to $675 million, with the acquisition aiming to accelerate the development of Convergence's pipeline, in particular CNV1014802 – a Phase II small molecule sodium channel blocking candidate.[21] In October 2015, the company announced that it would lay off 11% of its workforce, effective immediately.[22]

On May 3, 2016, Biogen announced to spin off its hemophilia business, known as Bioverativ. The hemophilia business would become an independent publicly traded company. Bioverativ offered two hemophilia drugs in 2016, Alprolix and Eloctate, and plans on developing its Hemophilia-focused goals.[23]

In 2016, Biogen released Spinraza (nusinersin), a treatment for Spinal Muscular Atrophy. The drug is among the most expensive treatments available, with a price of $750,000 for the first year of doses, and $375,000 for each subsequent year and likely for the rest of a patient's life.[24] While there still isn't a cure, Spinraza significantly improves the quality of life in infants and adults.

In 2017, Biogen announced that its drug Fampyra converted from conditional marketing authorization to standard marketing approval. EU multiple sclerosis (MS) patients use Fampyra to improve walking.[17]

In February 2020, Biogen and Sangamo Therapeutics announced a global licensing deal to develop compounds for neuromuscular and neurological diseases.[25]

In September 2020, Biogen Inc. made a $10 million deposit in OneUnited Bank to provide more capital to fund home loans and commercial development in Black communities.[26] In November, the company announced it would acquire a $650 million stake in Cambridge-based Sage Therapeutics and make an upfront payment of $875 million, in order to jointly develop a number of depression treatments.[27]

In July 2023, it was announced Biogen had acquired the Plano, Texas-headquartered biotech company, Reata Pharmaceuticals for nearly $6.5 billion.[28]

In May 2024, Biogen acquired Human Immunology Biosciences (HI-Bio) for $1.15 billion.[29]

### Aducanumab

[edit]

Main article: Aducanumab

In 2007, the company reached a licensing agreement with Neurimmune, a spin-off from the University of Zurich, for the Alzheimer's disease drug, Aducanumab, developed by this Swiss company. Later, Neurimmune sold its rights for license fees for $200 million to Biogen.[3]

In December 2014, Biogen announced that Aducanumab for Alzheimer's treatment was preparing to go through a late-stage trial of its experimental Alzheimer's disease treatment after the medication dramatically improved cognition and reduced brain plaque levels in early-stage study.[30]

In March 2015, Aducanumab became the first experimental Alzheimer's treatment to show significant results in regard to slowing down cognitive decline and reducing brain-destroying plaques.[31] In July 2015, Biogen initiated two late-stage studies called ENGAGE and EMERGE, which will assess Aducanumab in adults with early Alzheimer's disease.[32]

In 2016, Aducanumab decreased amoyloid-beta in the brains of people with early-stage Alzheimer's disease, according to a report published in Nature on August 31, 2016.[33] On March 21, 2019, Biogen announced that the Phase 3 clinical trials of Aducanumab were halted.[34] Biogen announced it would acquire Nightstar Therapeutics for $25.50 per share ($800 million in total). Nightstar focused on adeno-associated virus based gene-therapies for inherited retinal disorders.[35][36] With a setback in their drug research, Biogen's shares fell sharply that same month.[37] It ended the trial of Aducanumab, which it was making along with Eisai.[38] In October 2019, however, they announced that they would pursue FDA approval together with Eisai.[39]

On October 22, 2019, despite two Phase 3 clinical trials being previously halted for futility, Biogen announced its plan to submit for FDA's approval of Aducanumab.[40] In May 2020, Biogen wrapped up construction on a state-of-the-art facility in Solothurn, Switzerland, which will produce Aducanumab by late 2021, alongside its North Carolina manufacturing facility. The monoclonal antibody, co-developed with Eisai, attracted considerable interest from biotech investors when Warren Buffett's Berkshire Hathaway bought 648,447 Biogen shares at a combined value of $192.4 million.[41]

On July 8, 2020, Biogen and Eisai announced that both companies had together successfully submitted for Aducanumab's FDA regulatory and marketing approval.[42]

On June 7, 2021, the FDA gave accelerated approval to Aducanumab under the name Aduhelm,[43] which proved to be controversial.[44][45] The drug was priced at $56,000 US dollars per year, but it was not covered by many insurers as they awaited further proof that the drug was effective.[46] The US Government did not subsidise it outside clinical trials.[47] According to the FDA's website, the drug was proven to reduce amyloid-beta plaques in the brain, which was likely to benefit patients. The FDA has stated that if the post-approval trial did not indicate that Aduhelm works, the drug may be taken out of the market.[48]

Biogen abandoned the drug in January 2024, for financial reasons.[49]

### Bioverativ

[edit]

In May 2016, the company announced that it would spin off its hemophilia drug business (Eloctate and Alprolix) into a public company.[50] In August, the company announced that the spun off company would be called Bioverativ, in order to show heritage with Biogen.[51] The company would trade on the NASDAQ exchange under the ticker symbol BIVV[52][53] and would look to be spun off in early 2017.[54] Bioverativ was acquired by Sanofi in 2018 for about $11.6 billions[55][56][57] ($105 per share in cash).[58]

## Pipeline

[edit]

Biogen focused its R&D efforts on the discovery and development of treatments for patients with high unmet medical needs in the areas of neurology, hematology, and immunology.[citation needed]

Investigational MS medicines:

* Daclizumab High-Yield Process (DAC HYP): is being developed as a potential once-monthly subcutaneous injection in the treatment of relapsing-remitting multiple sclerosis (RRMS). DAC HYP is being developed in collaboration with Abbvie, Inc. In June 2014, the companies announced positive top-line results from the Phase III DECIDE clinical trial, where DAC HYP demonstrated superiority over interferon beta-1a in annualized relapse rate.[92]
* Anti-LINGO-1 (BIIB033) (Opicinumab): is the first candidate being investigated for its potential to remyelinate and repair neurons damaged by MS, currently in Phase 2 trials.[93]

Biogen has several candidates in Phase 1 and 2 clinical trials in neurodegenerative and immunological diseases including MS, neuropathic pain, spinal muscular atrophy and lupus nephritis:

* Phase 2a: anti-LINGO-1 molecule (Opicinumab) in acute optic neuritis
* Phase 2b: anti-TWEAK monoclonal antibody in lupus nephritis
* Phase 2a: STX-100 in patients with idiopathic pulmonary fibrosis
* Phase 2: Neublastin for neuropathic pain in 2013
* Phase 1/2: BIIB067 (ISIS-SOD1Rx) for amyotrophic lateral sclerosis, in collaboration with Ionis

Biogen also has several development agreements in place with Ionis Pharmaceuticals to collaborate to leverage antisense technology in advancing the treatment of neurological disorders.[94]

In February 2012, Biogen formalized a joint venture with Samsung, creating Samsung Bioepis. This joint venture brings Biogen's expertise and capabilities in protein engineering, cell line development, and recombinant biologics manufacturing to position the joint venture so Biogen can participate in the emerging market for biosimilars.[95]

In early 2014, Biogen entered into an agreement with Eisai, Inc., to jointly develop and commercialize two of their candidates for Alzheimer's disease, which have the potential to reduce Aβ plaques that form in the brains of patients, as well as to slow the formation of new plaques, potentially improving symptoms and suppressing disease progression.[94]

Biogen also has since 2015 an agreement with AGTC to develop gene therapy for several genetic diseases, including X-linked retinoschisis (XLRS) and X-linked Retinitis pigmentosa (XLRP) ophthalmologic diseases. To this aim, Biogen paid AGTC $124 million, including an equity investment of $30 million, and up to 1,1 billion in future milestones.[96]

In March 2019, Biogen halted Phase 3 trials of Alzheimer's disease drug Aducanumab after "an independent group's analysis show[ed] that the trials were unlikely to 'meet their primary endpoint.'"[97] However, in October 2019 they reversed their plans and said that they would be pursuing US FDA approval for Aducanumab. The reversal came after Biogen said a new analysis of a larger patient pool showed promising results.[39] In July 2020, Biogen completed submission of a Biologics license application (BLA) to the FDA for review, and requested accelerated review.[98] However, an advisory panel for the FDA voted against approval of this drug.[99] On June 7, 2021, the FDA granted approval of Aducanumab for the treatment of Alzheimer's disease. Aducanumab was approved using the accelerated approval pathway, and Biogen will be required to conduct a post-approval clinical trial to verify clinical benefit for continued approval.[100]

## Lawsuits

[edit]

In September 2022, Biogen agreed to pay $900 million to the U.S. federal government, states, and a whistleblower. Biogen had bribed doctors between 2009 and 2014 to increase prescriptions of Avonex, Tysabri, and Tecfidera (all for multiple sclerosis).[101]
