Janssen Pharmaceuticals is a pharmaceutical company headquartered in Beerse, Belgium, and wholly-owned by Johnson & Johnson. It was founded in 1953 by Paul Janssen.

In 1961, Janssen Pharmaceuticals was purchased by New Jersey-based American corporation Johnson & Johnson, and became part of Johnson & Johnson Pharmaceutical Research and Development (J&J PRD), now renamed to Janssen Research and Development (JRD), which conducts research and development activities related to a wide range of human medical disorders, including mental illness, neurological disorders, anaesthesia and analgesia, gastrointestinal disorders, fungal infection, HIV/AIDS, allergies and cancer. Janssen and Ortho-McNeil Pharmaceutical have been placed in the Ortho-McNeil-Janssen group within Johnson & Johnson Company.



Janssen (Leiden, 2021)

The early roots of what would become Janssen Pharmaceuticals date back to 1933. In 1933, Constant Janssen, the father of Paul Janssen, acquired the right to distribute the pharmaceutical products of Richter, a Hungarian pharmaceutical company, for Belgium, the Netherlands and Belgian Congo. On 23 October 1934, he founded the N.V. Produkten Richter in Turnhout. In 1937, Constant Janssen acquired an old factory building in the Statiestraat 78 in Turnhout for his growing company, which he expanded during World War II into a four-story building. Still a student, Paul Janssen assisted in the development of paracetamol (USP: acetaminophen, often referred to generically under the trademark Tylenol) under the name Perdolan, which would later become well-known. After the war, the name for the company products was changed to Eupharma, although the company name Richter would remain until 1956.[3]

Paul Janssen founded his own research laboratory in 1953 on the third floor of the building in the Statiestraat, still within the Richter-Eurpharma company of his father. In 1955, he and his team developed their first drug, Neomeritine (ambucetamide), an antispasmodic found to be particularly effective for the relief of menstrual pain. On 5 April 1956, the name of the company was changed to NV Laboratoria Pharmaceutica C. Janssen (named after Constant Janssen). On 27 April 1957, the company opened a new research facility in Beerse, but the move to Beerse would not be completed until 1971–1972. On 2 May 1958, the research department in Beerse became a separate legal entity, the N.V. Research Laboratorium C. Janssen.

On 24 October 1961, the company was acquired by the American corporation Johnson & Johnson. The negotiations with Johnson & Johnson were led by Frans Van den Bergh, head of the board of directors. On 10 February 1964, the name was changed to Janssen Pharmaceutica N.V. and the seat of the company in Turnhout was also transferred to Beerse. The company was led by Paul Janssen, Bob Stouthuysen and Frans Van Den Bergh. When, in 1971-1972 the pharmaceutical production also moved to Beerse, the move from Turnhout was completed. Between 1990 and 2004, Janssen expanded worldwide, and the company grew in size to about 28,000 employees worldwide.

From the beginning, Janssen emphasized as its core activity research for the development of new drugs. The research department which was established in Beerse in 1957, developed into a large research campus. In 1987, the Janssen Research Foundation (JRF) was founded which performs research into new drugs at Beerse and in other laboratories around the globe. Janssen became the Flemish company with the largest budget for research and development. Beside the headquarters in Beerse with its research departments, pharmaceutical production and the administrative departments, Janssen Pharmaceutica in Belgium still has offices in Berchem (Janssen-Cilag), a chemical factory in Geel, and Janssen Biotech in Olen.

The Chemical Production plant in Geel makes the active ingredients for the company's medicines. In 1975, the first plant of a new chemical factory Plant I was established in Geel, Plant II was opened in 1977, Plant III' in 1984, and Plant IV in 1995. In 1999 the remaining chemical production in Beerse was transferred to Geel. About 80% of its active components are manufactured here. The site in Geel also manufactures about two-thirds of the worldwide chemical production of the pharmaceutical sector of Johnson & Johnson. In 1995, the Center for Molecular Design (CMD) was founded by Paul Janssen and Paul Lewi.

In 1999, clinical research and non-clinical development become a global organization within Johnson & Johnson. In 2001, part of the research activities was transferred to the United States with the reorganization of research activities in the Johnson & Johnson Pharmaceutical Research Development (JJPRD) organization. The research activities of the Janssen Research Foundation (JRF) and the R.W. Johnson Pharmaceutical Research Institute (PRI) (United States) were merged into the new global research organization. A new building for pharmaceutical development was completed in Beerse in 2001. In 2002, a new logistics and informatics centre was opened at a new site, Beerse 2. In 2003 two new research buildings were constructed, the Discovery Research Center (DRC), and the Drug Safety Evaluation Center (DSEC). On 27 October 2004, the Paul Janssen Research Center, for discovery research, was inaugurated.

In 2011, Johnson & Johnson subsidiary Centocor became Janssen Biotech, part of Janssen Pharmaceuticals.[1]

Also in 2011, Johnson & Johnson acquired Crucell, and assigned it to Janssen. The acquisition of Crucell provided Janssen with a disease prevention arm. By 2014, Crucell was renamed as Janssen Vaccines.[4][2]

In March 2015, Janssen licensed tipifarnib (a farnesyl transferase inhibitor) to Kura Oncology who will assume sole responsibility for developing and commercialising the anti-cancer drug.[5] Later in the same month the company announced that Galapagos Pharma had regained the rights to the anti-inflammatory drug candidate GLPG1690 as well as two other compounds including GLPG1205 (a first-in-class inhibitor of GPR84).[6]

In May 2016, the company launched a collaboration MacroGenics and their preclinical cancer treatment, MGD015. The deal could net MacroGenics more than $740 million.[7]

In September 2017 it was announced that Janssen teamed up with the Biomedical Advanced Research and Development Authority (BARDA), a unit of the U.S. Department of Health and Human Services, to create pandemic flu vaccines. BARDA is giving Janssen $43 million in the first year and $273 million over five years for the contract. One of the projects in the contract is the development of a universal flu vaccine. The intent of the vaccine would be to protect people against all or most flu strains.[8]

On 5 March 2019, the Food and Drug Administration approved Janssen's Spravato (esketamine nasal spray) for treatment-resistant major depressive disorder. This marked the first approval of a new type of antidepressant in decades.[9]

In 2021, Janssen was named as a defendant in a trial against several opioid manufacturers filed by New York Attorney General Letitia Jame.[10] The company was later removed from the case after Johnson & Johnson agreed to a pay a $230 million settlement to New York State.[11]

COVID-19 vaccine development[edit]

On 27 March 2020, the U.S. Biomedical Advanced Research and Development Authority (BARDA) allocated $456 million for J&J (Janssen) to develop a vaccine against the novel coronavirus.[12][13]

In China[edit]


Janssen Pharmaceuticals was the first Western pharmaceutical company to set up a pharmaceutical factory in the People's Republic of China.[14]

In 1976, Paul Janssen met Ma Haide (born George Shafik Hatem), a Lebanese-American doctor who had started working in China in 1933. After three days of meetings, the two agreed to bring a modernized pharmaceutical business to China. When Deng Xiaoping opened China to the West in 1978, Janssen sent Paul Appermont and Joos Horsten to set up the project.[14]

In 1983, Janssen signed a cooperation contract to modernize production in an old chemical factory in the city of Hanzhong, in Shaanxi province. This factory would soon produce the active compound of some Janssen products, such as mebendazole. In 1985, now operating as Xian-Janssen Pharmaceuticals, a new large factory was opened in the city of Xi'an, also in Shaanxi province.[14]

Risperdal deception[edit]

In 2004, the United States Department of Justice began investigating sales practices surrounding the antipsychotic drug risperidone (Risperdal). In 2010, the agency joined a whistleblower suit alleging that despite being warned by the U.S. Food and Drug Administration not to promote Risperdal as effective and safe for elderly patients, in whom it was known to be associated with early death, Johnson & Johnson and Janssen Pharmaceuticals paid pharmacists at Omnicare, the largest supplier of pharmaceuticals to nursing homes, tens of millions of dollars in bribes and kickbacks to promote the drug to physicians for this unapproved use.[24][25]

The lawsuit resulted in a 2012 provisional settlement totaling $2.3 billion,[26] with Omnicare having already settled for around $100 million.[26] Four states were awarded damages: Louisiana ($258 million in 2010), South Carolina ($327 million in 2011), Texas ($158 million in 2012), and Arkansas ($1.2 billion in 2012).[27]

Former head of sales and president of Janssen Alex Gorsky, who according to the Department of Justice "was actively involved" in the fraud, became CEO of Johnson & Johnson in 2012.[28]
