Our focus - immunology

We understand how distressing and debilitating immune-mediated inflammatory diseases (IMIDs) can be, which is why we strive to provide treatments that give you or your loved ones relief from the daily discomfort and stress that these conditions can pose. Rest assured, we are committed to building on our breakthroughs that have already changed the lives of millions of people around the world.

Our commitment to patients

Janssen is committed to help ease the challenges that people living with immune-mediated inflammatory diseases have to endure for the rest of their lives.

Our goal is to improve the diagnosis of immune-mediated inflammatory diseases, improve patients’ access to the best possible treatments and continue to provide new and better medicines.

We never underestimate the human impact of immune-mediated inflammatory diseases

People living with immune-mediated inflammatory diseases can be affected for the rest of their lives, yet the impact of these conditions is dramatically underestimated. As some of these diseases are not readily recognised, people can suffer silently before eventually receiving treatment.

Immune-mediated inflammatory diseases are the result of a relentless, internal, immunological ‘storm’, which can cause pain and discomfort that many people live with every day[1], [2], [3]. People may further experience stigma, isolation, decreased productivity and psychological issues[2], [4], [5], [6], [7]. And it’s not just them, their families and loved ones can be affected too[4] .

Our mission is clear: we won’t rest until we achieve a world free from immune-mediated inflammatory diseases.

Immunology facts

  • Nearly 1 in 10 people in Europe are living with an immune-mediated inflammatory disease.[8]
  • Living with an immune-mediated inflammatory disease has a similar impact on psychological and physical functioning to cancer, heart disease and hypertension.[9],[10]
  • They are debilitating and chronic diseases. Pain, fatigue and inability to perform everyday tasks are the most apparent symptoms.[11],[12], [13], [14], [15], [16], [17]
  • Many people also suffer from severe additional conditions as a result, such as depression.[13],[14], [18],[19]

Janssen’s pioneering breakthroughs change lives

We’ve always been innovative in our science, finding new and more effective ways to transform the course of immune-mediated inflammatory diseases and calm the inner battle waging within patients’ bodies.

Since the advent of targeted biologic therapy over 35 years ago, we developed the first licensed monoclonal antibody to act directly on the immune system, providing patients with an unprecedented level of efficacy and symptomatic relief.[20]

Our breakthroughs have changed the lives of millions of people around the world living with some of the most common immune-mediated inflammatory diseases.

We will continue our search for newer and better medicines

We’ve continued to advance our knowledge of the inflammatory process. We’ll carry on working on better therapies to try to stop and even cure immune-mediated inflammatory diseases, where the impact on patients is high and/or where there remains a need for better treatments.

Working together to achieve a world where immune-mediated inflammatory diseases are a thing of the past

Our commitment to immune-mediated inflammatory diseases goes beyond our medicines. We support patients through collaborations with patient advocacy organisations.[22]

We invest heavily in continuous medical education of doctors and care providers, uniting different therapeutic areas to share expertise and best practices.

We also bring together the brightest minds, including doctors, nurses, patients and patient groups, scientists and policy makers to turn scientific discoveries into treatment breakthroughs, and to ensure that people can benefit from the best treatments when they need them.

We are for the PEACE Within

The PEACE Within represents our commitment to supporting people living with immune-mediated inflammatory diseases. Every member of our Janssen team is striving to bring the PEACE Within to people living with immune-mediated inflammatory diseases.

Through our unceasing research, we continue to improve our understanding of the immune system, and to discover and develop better treatments.

Even though we have made great progress in the last decade for the treatment of immune-mediated inflammatory diseases, our work aims to raise the bar to make periods of disease remission more durable and allow patients with these debilitating diseases to lead normal lives.
