Our Clinical Trials   

A clinical trial is a type of research study designed to determine if an investigational medicine is safe, how it works in the body and if it works to treat a specific disease. Please visit to learn more about our ongoing clinical trials evaluating our investigational medicines and to access information on past clinical trials. 

This dedicated clinical trial website serves as a resource for patients, medical professionals, researchers and others interested in learning about past and ongoing clinical trials. It provides information about our policies and values as we carry out clinical research and our commitment to integrity and transparency. By providing access to clinical trial protocol information and summary results, we seek to provide clinical research transparency to spur scientific innovation, improve medical care and build public trust.
