Our Focus

Our Four Disease Areas of Focus

At Janssen we engineer solutions with our patients in mind. That means delivering more than just medicine. We search for treatments and solutions that address some of the most complex medical needs of our time.

We start by identifying patients' needs and then set about developing strategies to meet them. We know answers don’t always lie within our own four walls. So we establish strategic relationships and collaborations with leading researchers to rise up to the challenges.

We use our world-class research and development expertise to find treatments that may transform patients' lives. 

No matter where medical breakthroughs occur, our goal remains the same. To deliver value to patients that goes beyond delivering a treatment. Our focus is on four key diseases that have significant unmet need:

Oncology research

Through groundbreaking research and innovative partnerships, we aim to transform cancer into a preventable, chronic or curable disease. Our goal is to deliver diagnostic and therapeutic options that prolong and improve patients' lives. We are focused on key cancer types, including blood cancers, prostate cancer and lung cancers.  Learn more

Studies in neuroscience

With a longstanding, continued commitment to neuroscience, our vision is to reduce the burden, disability and devastation caused by serious neuropsychiatric diseases and pain conditions and restore hope for patients. Our three key areas are neurology (which includes Alzheimer's disease); psychiatry focused on mood disorders (such as bipolar disease and major depressive disorder) and schizophrenia; and pain with a particular interest in chronic pain states and neuropathic pain. Learn more
