History

Perspective


Amgen was established in Thousand Oaks in 1980, as Applied Molecular Genetics.[5][6] Amgen was backed by a small group of venture capitalists, and its early focus was on recombinant DNA technology and recombinant human insulin.[7]
Its initial scientific advisory board consisted of Norman Davidson, Leroy Hood, Arnold Berk, John Carbon, Robert Schimke, Arno Motulsky, Marvin H. Caruthers, and Dave Gibson.[8] In October 1980, Amgen named George Rathmann its first president and chief executive officer.[7]
On June 17, 1983, Amgen went public, selling two million common shares and raising nearly $40 million.[9][10][11] That same year, after more than two years of work, an Amgen research team led by Fu-Kuen Lin had a breakthrough in finding and cloning the erythropoietin gene, a protein created in the kidney that stimulates red blood cell production. Lin's team created what would become Epogen (epoetin alfa).[12][13]
In June 1984, Amgen and Kirin formed a joint venture giving Kirin the rights to Epogen in Japan.[14][15] A year later, Amgen researcher Larry Souza and his team cloned granulocyte colony-stimulating factor (G-CSF), leading to the development of Neupogen (filgrastim).[13][16][17]
In October 1988, Gordon Binder was named CEO, succeeding George Rathmann.[18] The following year, in 1989, Amgen received approval for the first recombinant human erythropoetin product, Epogen (epoetin alfa).[19]
In February 1991, Amgen received FDA approval for Neupogen for the prevention of infections in patients whose immune systems are suppressed due to cancer chemotherapy.[20]
Amgen opened a new manufacturing facility in Puerto Rico, in March 1993, which later became the company's flagship manufacturing site.[21][22]
In 1994, Amgen became the fifth company to receive the U.S. Department of Commerce's National Medal of Technology and Innovation, in recognition of its work developing medicines to improve quality of life for kidney and cancer patients.[23] Also around this time, Amgen researcher Steve Elliott and his team added more sugar molecules to erythropoietin, causing it to remain in the body longer. This led to the development of Aranesp (darbepoetin alfa).[24]
2000-2014
Binder was succeeded as CEO by Kevin W. Sharer in 2000.[25] Robert A. Bradway became Amgen's president and chief executive officer in May 2012, following Sharer's retirement.[26]
In June 2010, Amgen received FDA approval for Prolia, a protein drug for the treatment of post-menopausal osteoporosis.[27] In clinical trials, Prolia reduced the rate of vertebral fractures by 61% and the risk of hip fractures by 40%.[28] In November 2010 the FDA approved Xgeva for the prevention of complications of bone metastases in patients with solid tumors.[29] The clinical trials primarily enrolled patients with breast or prostate cancer.
In March 2011, Amgen acquired a manufacturing facility near Dublin, Ireland, in March.[30]
Amgen also opened an affiliate in China in 2013.[31][32]
In November 2014, the company halted all trials of rilotumumab in advanced gastric cancer patients after one of the trials found more deaths in those who took the compound with chemotherapy, than those without.[33] Also in November 2014, the company, in conjunction with AstraZeneca, reported positive results for brodalumab in a Phase III trial comparing the compound with ustekinumab and a placebo in treating psoriasis.[34] In the same month, construction was completed on Amgen's next-generation biomanufacturing facility in Singapore.[35] Blincyto (blinatumomab) was approved by the FDA in December of that year.[36][37]
2015-2020
The company announced in March 2015 that it would license its Phase II candidate drug AMG 714 to Celimmune, which will develop the anti-IL-15 monoclonal antibody for treatment against diet nonresponsive celiac disease and refractory celiac disease.[38] In August of that year, Repatha (evolocumab) was approved by the FDA in August.[39]
In September 2016, the company announced it would purchase the rights to Boehringer Ingelheims Phase I bispecific T-cell engager compound (BI 836909, now AMG 420) for use in the treatment of multiple myeloma.[40] Also in September, the FDA approved Amjevita (adalimumab-atto).[41] The FDA approved Parsabiv in February 2017[42] and Mvasi (bevacizumab-awwb) in September.[43]
Amgen began constructing a next-generation biomanufacturing plant at its West Greenwich, Rhode Island, campus in July 2018.[44]
In January 2019, Evenity (romosozumab) received approval in Japan,[45][46] followed by FDA approval in April.[47] In June, Kanjinti (trastuzumab-anns) was approved by the FDA.[48] In November, Amgen awarded a $2 million grant to the CDC Foundation to launch the latter's EmPOWERED Health Program, promoting patient engagement in decision making for their cancer treatment.[49] In December, the FDA approved Avsola (infliximab-axxq).[50]
In September 2019, FDA granted fast track designation to sotorasib for the treatment of metastatic non-small-cell lung carcinoma (NSCLC) with the KRAS G12C mutation.[51]
In April 2020, Amgen established Amgen K.K. as the company's wholly-owned affiliate in Japan.[52][53] The company announced in July that the United States Court of Appeals for the Federal Circuit had upheld the validity of two Amgen patents that described and claimed Enbrel and methods for making it. The appellate court affirmed an August 2019 decision by the United States District Court for the District of New Jersey and rejected Sandoz's attempt to invalidate the patents on Enbrel.[54] Amgen joined the Dow Jones Industrial Average on August 24, 2020.[55]
In August 2020, Amgen, Takeda Pharmaceutical Company, and AbbVie, as part of a COVID-19 research and development (R&D) alliance, announced the first patients enrolled in the I-SPY COVID clinical trial. The trial evaluated the efficacy of Otezla and two other medicines in severely ill, hospitalized COVID-19 patients who required high-flow oxygen.[56]
In September 2020, Amgen and Eli Lilly and Company announced a global manufacturing collaboration for COVID-19 antibody therapies.[57] Later that month, the FDA approved Riabni (rituximab-arrx), a biosimilar to Rituxan.[58]
In October 2020, Amgen announced positive topline Phase 2 results from the CodeBreaK 100 clinical study, evaluating sotorasib in 126 patients with KRAS G12C-mutant advanced NSCLC who had failed three or fewer prior lines of anti-cancer therapies (including immunotherapy and/or chemotherapy).[59] Amgen, the Global Coalition for Adaptive Research, and Eisai Co., Ltd. also announced enrollment of the first patient in a study testing multiple interventions for the treatment of patients hospitalized with COVID-19.[60]
In November 2020, Amgen, Takeda, and UCB, as part of the COVID R&D alliance, announced the first patient enrolled in another trial evaluating Otezla and two other drugs as treatments for COVID-19.[61] Amgen also announced that it would terminate its collaboration with Cytokinetics and transition the development and commercialization rights for omecamtiv mecarbil and AMG 594.[62] Amgen and AstraZeneca announced positive topline results from a Phase 3 trial in which the investigational medicine tezepelumab demonstrated a statistically significant reduction in exacerbations in patients with severe asthma.[63]
In December 2020, the FDA granted breakthrough therapy designation to sotorasib for advanced or metastatic non-small cell lung cancer patients with KRAS G12C mutation.[64]
The company announced it would acquire Five Prime Therapeutics and its lead candidate, bemarituzumab, for $1.9 billion in March 2021.[65][66][67] In the same month, Amgen acquired Rodeo Therapeutics for $720 million.[68][69]
In May 2021, sotorasib received accelerated approval from FDA for treatment of adult patients with NSCLC whose tumors have a KRAS G12C mutation and who have received at least one prior systemic therapy; this was the first approved targeted therapy for tumors with any KRAS mutation.[70] Similar approvals for sotorasib in NSCLC followed in January 2022 in Europe[71] and Japan.[72] The FDA approved Amgen's Lumakras in May for treatment of patients with KRAS-G12C-mutated non-small cell lung cancer.[73]

Amgen announced a research collaboration in January 2022 with Generate Biomedicines across multiple modalities and several therapeutic areas for up to $1.9 billion.[80][81] The company also launched a multi-target collaboration with Arrakis Therapeutics to identify novel targeted RNA degrader therapeutics.[82][83] The next month, Amgen entered a multi-year collaboration with Plexium to discover novel targeted protein degradation therapies.[84][85] Also in February, Amgen issued its first green bond to fund various environmentally friendly initiatives across the company.[86][87] The company broke ground on a new manufacturing facility in Holly Springs, North Carolina, in March.[88][89] In August, the company agreed to acquire ChemoCentryx for $3.7 billion in an all-cash deal.[90] ChemoCentryx is the maker of Tavneos—a drug treatment for rare diseases called anti-neutrophil cytoplasmic autoantibody-associated vasculitis—which was approved last year.[91]
In September 2022, data from a late-stage study showed the company's cancer pill Lumakras (sotorasib) beating out chemotherapy. This was the first approved drug in the set of treatments that target KRAS, among the most common generic mutations found in cancers. The drug was approved in 2021 with a list price of $17,900 per month.[92]
In October 2023, Amgen acquired Horizon Therapeutics, specializing in drugs for rare diseases, for $27.8 billion.[93][94]
