Founded by Paul Janssen in Beerse, Belgium in 1953 and now operating as the pharmaceutical division of Johnson & Johnson, Janssen Global stands among the world's foremost research-driven pharmaceutical organisations. The business concentrates scientific and commercial resources on discovering, developing and delivering transformative medicines across oncology, immunology, infectious diseases and neuroscience, with a particularly strong record in haematological malignancies and autoimmune conditions.
Janssen's approved portfolio illustrates the breadth of its therapeutic reach. In oncology and haematology, Darzalex (daratumumab) has become a standard-of-care option across multiple myeloma lines, while Imbruvica (ibrutinib), developed in collaboration with AbbVie, is approved across several B-cell malignancies. Zytiga (abiraterone acetate) remains a recognised treatment in metastatic prostate cancer. In immunology, Stelara (ustekinumab) and Tremfya (guselkumab) address moderate-to-severe plaque psoriasis and other inflammatory conditions. The neuroscience portfolio includes Spravato (esketamine), a nasal-spray formulation approved for treatment-resistant depression in adults. HIV and tuberculosis medicine reflects a long-standing infectious disease commitment carried through products such as Edurant (rilpivirine) and contribution to combination regimens used globally.
Research and development hubs span Beerse, Spring House (Pennsylvania), La Jolla (California), Leiden in the Netherlands and Shanghai, supporting a pipeline that extends from early discovery through late-stage clinical programmes. Janssen works alongside academic medical centres, biotech partners and health systems to accelerate access. As a central component of Johnson & Johnson's pharmaceutical segment, operating under the J&J Innovative Medicine banner from 2023, the organisation benefits from the group's global manufacturing network, regulatory infrastructure and substantial annual R&D investment. Its pharmaceutical pipeline spans both small molecules and large biologics, with active programmes in areas such as solid tumours, multiple sclerosis and pulmonary arterial hypertension.
