We continue to develop new treatments to control inflammation and autoimmune conditions, in the hopes of reducing the toll that they take on people’s lives.

Clinical trials are an important part of this effort. We invite you to explore our clinical trials in inflammation and immunology below.

Together, we can advance breakthroughs for all 

It is important to have medicines that can treat diseases and conditions in anyone, regardless of their background.

This starts with clinical trials. Many biological and environmental factors, such as genetics, race, ethnicity, age, sex, gender, and where you are born can impact how you may respond to a medicine. Even where and how you live, work and play can affect your health, your risk for disease, or your response to treatment.

When clinical trial participation reflects the diversity of our communities, the more we learn about potential medicines, including how they work for different people. Everyone needs to be represented.

About immunology and inflammation

In certain cases, the immune system mistakenly targets a part of the body that it believes is harmful. The mistaken immune response commonly results in inflammation and damage to healthy tissues. This is known as an autoimmune disease.

We continue to develop new treatments to control inflammation and autoimmune conditions, in the hopes of reducing the toll that they take on people’s lives.

Frequently asked questions

What are autoimmune diseases?

The immune system plays an important role in protecting your body from bacteria, viruses, and other things that could make you sick. The immune system is usually pretty good at defending the body from infections and other unwanted changes. However, in some people, the immune system mistakenly attacks healthy parts of the body. The mistaken attacks may be against specific cells, tissues, and organs, causing damage that can sometimes become life-threatening. This is known as an autoimmune disorder.

What is inflammation and why is it important?

Inflammation is the immune system’s response to a problem such as a germ or physical injury. Inflammation may be experienced as redness, swelling, or pain. Without inflammation, wounds would have trouble healing and infections could become worse.

However, if the inflammation is chronic (continuing for too long), it could begin damaging healthy cells, tissues, and organs. This can lead to serious conditions such as joint damage and cardiovascular diseases.

What happens in a clinical trial?

What happens in a clinical trial depends on the ‘protocol.’ A protocol is a detailed plan that explains the purpose of the clinical trial and how it will be run. If you consider joining a clinical trial, these details will be explained to you as part of the informed consent process. They include: 
 

  • the length of the clinical trial 
  • the study medicines, procedures, and tests in the clinical trial
  • the schedule of study activities 
  • information about who can participate 
  • how side effects will be tracked, managed, and reported 
  • the rules that must be followed 
     

A clinical trial may also have aspects such as randomization, placebo, or blinding.

Who can join a clinical trial?

We encourage everybody to consider joining clinical trials. There are many types of clinical trials that study different aspects of health in people with a variety of backgrounds and conditions. Each clinical trial has its own criteria for who may participate. These are called eligibility criteria.  
 
Eligibility criteria include things like your age, sex, overall health, type of condition, and your medical treatment history. As part of the steps to join a clinical trial, the study doctor will confirm whether you meet all eligibility criteria and are able to participate.

Participation in a clinical trial is always voluntary. The decision to join is personal, and it is yours.
